Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors.
Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them.
1. What makes us human?
Just looking at your DNA won't tell you - human DNA is 99 percent identical to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on – have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity (能力) for co-operation and our trading skills are what make us unique.
2. Why do we dream?
Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream.
Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain.
3. Could we someday live forever?
Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes（糖尿病） and cancer, are diseases of aging, treating aging itself could be the key to extending our lives.
Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism (新陈代谢), which are all leading to the invention of drugs that can slow down the aging process.
If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.
小题1:The main point of the passage is ______.

A．to inform people of the knowledge about the universe and nature

B．to introduce major breakthroughs that have been made in science

C．to present some questions we can't yet answer

D．to explain what were once mysteries to our ancestors

小题2:Chimpanzees and bananas are mentioned as examples to prove that ______.

A．human beings are actually not different from other animals

B．animals have completely different DNA from that of plants

C．both animals and plants share the same amount of DNA

D．DNA alone is not good enough to make humans different

小题3:The underlined word "identical" is closest in meaning to ______.

A．mysterious

B．unique

C．advanced

D．same

小题4:Which of the following statements is TRUE according to the passage?

A．What were mysteries to our ancestors are considered to be common sense now.

B．Now we know much more about dreams than our ancestors did in the past.

C．With the invention of new drugs people can possibly live even longer.

D．If all the diseases can be treated people can theoretically live forever.

Black Box
You never see them, but they're with you every time you fly. They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫画) book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潜水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft's final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They're also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
小题1:What can we leam about the black box from the passage?

A．It helps an airplane function normally.

B．Its ability to avoid disasters is amazing.

C．It is necessary equipment on an airplane.

D．The idea for its design comes from a comic book.

小题2:From the black box on the Yemeni airliner we can get information about _____.

A．the scene of the crash and the damage

B．data for analyzing the cause of the crash

C．the total number of passengers on board

D．homing signals sent by the pilot before the crash

小题3:The Federal Aviation Authority required the black boxes be painted orange or yellow to

A．make them easily identified

B．meet the international standards

C．caution people to handle them with care

D．distinguish them from the color of the plane

小题4:What do we know about the black boxes from Air France Flight 447?

A．They have stopped sending homing signals.

B．They were destroyed somewhere near Brazil.

C．There is an urgent need for them to be restructured.

D．There is still a good chance of their being recovered.

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(伤害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch（伸展）to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.
Many snakes eat birds’ eggs or frogs（青蛙）. Others eat pests（害虫）, mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts.
小题1: Which of the following groups of food is usually had by a snake?

A．Mice, crops, birds’ eggs.

B．Pests, frogs, some animals, plants.

C．Birds’ eggs, frogs, all animals, other snakes.

D．Mice, frogs, pests, some animals, other snakes.

小题2:We should not kill a snake because

A．it is poisonous

B．it can do something useful for man

C．it will strike you in return

D．we are not experts

小题3:Snakes may do some valuable work by

A．eating pests, mice and some harmful animals

B．doing harm to other animals

C．eating birds’ eggs and frogs

D．both A and C

小题4:In writing this passage the writer mainly wants us to

A．have a better impression(印象) about snakes

B．like snakes

C．kill snakes with the help of experts

D．regard snakes as one of man’s best friends

This site , all-birds. com, is about bird watching. Enjoy your browsing. There is much to learn and see.
Bird Watching Equipment
Some items that might make bird watching more enjoyable are binoculars （双目望远镜） , a camera, some kind of system for keeping notes, and maybe a back pack． Birders often keep lists of the birds they see along with notes about the habits． There is some great bird log software that will let you keep records on your computer． For more details on choosing binoculars see our Binocular -Optics page．
Clothes
If you are walking through a wooded area just wear clothes you would wear on any hike or field trip． You are best off wearing clothes with dull colors that mix into the background． Greens, browns, and grays are good． Avoid fabrics that rustle（沙沙响）easily． Depending on the birds you are watching you may want to get rain gear, rubber boots and warm clothing． For birds such as owls that you might look for in the evening a strong flashlight is also handy．
Choosing a Bird Field Guide
Take a good field guide to identify birds． Look for clear color pictures that make it easy to recognize one bird from another． Next to each picture should be detailed descriptions of each bird's anatomy, habits, and what it eats． The guide should have information about what habitat each species uses． Many guides have maps showing the range of different birds along with their migration patterns．
Where and When to see Birds
Learning the habitats of birds in your area will increase the number of birds you see, and make your birding more enjoyable． If you know that Meadow larks are likely to be in open grassy areas, and dippers are forage along stream beds, you may be looking for them if you are in those types of habitats． Edge areas where different types of habitats meet will likely have more species in them． You are more likely to see specific birds at certain times of the day． For example songbirds are easier to see two to three hours after dawn, or just before sunset． This is when songbirds are most actively feeding． Many small birds will be silent or even hidden during the rest of the day． After sunup is the best time to see eagles and hawks． Visibility is best for hunting at this time, and they can soar on the thermal currents from the warmed air． Birds like owls are more likely to be seen in the evening． Many shorebirds and waders rest at high tide and feed when the water rises or falls．
Photographing Birds
Patience in Bird Photography
Most birds are afraid of people, and all species have their own comfort zone． With a little time you can learn the comfort zone of the birds you are photographing． Once they know that you are not a threat you may be able to get closer．
Type or Style
Your reason for photographing birds may determine your style and the kind of equipment you use． If you are just recording the kinds of birds you see you don't need to get as close, and you can use less expensive equipment, then you need for high quality prints.
Photographing Birds in Flight
Photographing birds in flight can be fun． Many digital cameras have a tracking function． With these you focus on the bird, and then as you track it the lens will keep focus．
Use Your Yard
Choose an open area where the birds will get direct sunlight, showing off their magnificent colors．
Try using props
Birds will often land on a stick or post near a seed feeder before going to the feeder． The background was just an out of focus fence but you can use anything you want for a background, and then wait for a bird to perch.
小题1:The main purpose of the passage is to _____.

A．attract more people to photograph birds

B．help birders learn how to identify and understand birds

C．call on people to set some comfort zones for birds

D．inform birders of the results of a scientific research on birds

小题2:Clothes in ______ are highly recommended when you are going bird watching．

A．red

B．yellow

C．brown

D．blue

小题3:________ are likely to be seen at 7 in the morning．

A．Owls

When my brother and I were young, my mom would take us on Transportation Days.
It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the train, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home—our first car ride of the day.
The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.
Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just lightrail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.
On Transportation Days, we might stop for lunch on Chestrut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river?
I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me.
小题1: According to the writer, what was the greatest benefit of her Transportation Days?

A．Building confidence in herself.

B．Reducing her use of private cars.

C．Developing her sense of direction.

D．Giving her knowledge about vehicles.

小题2: The underlined word “paralyzed”(in Para.5) is closest in meaning to “________”．

A．displayed

B．justified

C．ignored

D．ruined

小题3: Which means of transportation does the writer probably disapprove of?

A．Airplane.

B．Subway.

C．Train.

D．Car.

While learning the science lessons, I used to get a doubt--why ear, nose, tongue and eyes should be called as special senses? The basic reason is that these are the channels through which we maintain contact with the surroundings. Though apparently it may feel like these are individual sensory organs, they do show some connectivity. Interestingly, our hearing is less sharp after we eat a heavy food. Isn’t it good for a sound nap after a stomach-full meal? That does not mean we go deaf after a meal, but the hearing pitch（强度）does change after a heavy meal.
We usually give credit of the taste to our tongue, but do you know that unless saliva（唾液）dissolves something, our tongue cannot recognize the taste of the food eaten. Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds（味蕾）present on the tongue. Try to dry off your tongue and mouth with a tissue paper and then taste something.
Women are much better smellers than men. They are born with this characteristic ability and can correctly recognize the exact fragrance of the sample. We all can store almost 50,000 different smells, which are strongly tied to the memories.
Pupils（瞳孔）do not respond to light alone, but to the slightest bit of noise around too. Thus surgeons, watchmakers and those professionals who have to perform a much delicate job do prefer to have a sound-free environment. Even a small noise can enlarge their pupils, change the focus and make their vision less clear.
Each and every one of us has a particular or individualistic or characteristic smell, which is unique to us, except the twins. This smell is very subtle yet can be sensed even by a newborn. It may be due to this smell that the newborn recognizes the presence of his parents around.
小题1:What may happen after you have had a rich lunch?

A．Your eyes become weak and can not see well.

B．You may feel energetic and fresh.

C．Your hearing pitch may be decreased.

D．Your tongue may lose the function of taste.

小题2:. What does the author mean by the underlined sentence in paragraph 2?

A．Our tongues can’t be dried while eating something.

B．If your tongue is dried without any saliva on it, it will not work.

C．A tissue paper is the only thing that can be used to dry our tongues.

D．If your tongue is dried with a tissue paper, it may work as well as before.

小题3:What makes each person different from anyone else except twins according to the passage?

A．The number of sensory organs.

B．The functions of sensory organs.

C．The particular smell of a person.

D．The style of one’s behavior.

小题4:Which of the following may be the best title of this passage?

A．The Sensitivity of Sensory Organs

B．The Functions and Connections of Sensory Organs

C．A Newborn’s Sensory Organs

D．Different Senses Between Men and Woman

About seven years ago, whenever I notice someone looked nice, I started telling them they looked nice. Shortly afterwards, I came up with an observation: If you tell five people during the day that they look nice, at the end of the day, six people feel great. Here are some fruitful experiences I have with this.
One day, I was riding with a friend when we rolled to a stop at the traffic light. As we waited for the light to turn green, a man walked across the crosswalk. He looked very together, so I called out, “Hey, you look sharp today!” Pointing towards a building, he said, “Thanks, but I was sharper there.” His comment puzzled me. But before I could ask about it, the light turned green, and we drove on. I asked my friend what he meant. My friend informed me that we were at the corner of a radio station and the man was the voice on the radio. Then I understood. But no matter who he was the biggest thing for me was that he was smiling when he accepted my compliment (赞扬).
Later that day, there was a woman standing on the corner where we were turning, and I yelled (大喊) the compliment again, “You look nice!” She was just taking a sip of a bottle of water and started to laugh. I felt good to get a laugh.
Another day, while seated in a restaurant, there was a lady sitting near me. I really did not care for her skirt, but she did look nice in it, so I told her, “You look nice today.” She looked at me and rolled her eyes a little. Well, her friend sitting next to her told her, “He just gave you a compliment. Say thank you.” I don’t remember whether she said “thank you” or not, but what I did notice was that her friend was smiling at my “You look nice today” compliment.
小题1:The underlined word “sharp” in Paragraph 2 probably means_________.

A．attractive	B．sudden
C．strict	D．mild

小题2:Which of the following statements is NOT true according to the passage?

A．The first man the author praised accepted his compliment.

B．The first man the author praised worked at a radio station.

C．The woman standing on the corner didn’t like the compliment

D．The friend of the lady in the restaurant felt happy about the compliment.

小题3:What would be the best title of the passage?

A．Fruitful Experiences

B．Help Others, Help Yourself

C．Learn to compliment.

D．“You Look Nice Today”

Can we give a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot.
1. Protect wildlife habitat.
Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the only habitats that are left untouched by habitat destruction.
2. Reduce the threat of invasive (入侵的) species.
The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (资源) and habitat. They can even prey on native species directly, forcing native species towards extinction.
3. Place decals (贴花纸) on windows.
It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.
4. Slow down when driving.
Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障碍) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.
小题1: What would be the best title for this passage?

A．How animals go to extinction

B．The importance of protecting wildlife

C．What to do to help save wildlife

D．How to protect wildlife habitat

小题2:By writing the underlined sentence, the writer means that _____.

A．more parks and reserves should be built

B．we should have more habitats free of destruction

C．there is a need for improvement in parks and re-serves

D．parks and reserves are good examples of protecting wildlife

小题3:People are advised to put decals on windows to _____.

A．decorate the houses and beautify the environment

B．protect the windows from birds hitting

C．attract more birds to make homes nearby

D．avoid birds hitting the windows by mistake

小题4:The underlined phrase “prey on” in the passage means _____.

A．drive away

B．live with

C．kill for food

D．fight with
