Save the Animals
Animals are natural resources(资源) that people have wasted all through our history.
Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance (平衡) of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid(禁止) the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
小题1:Animals are important to us mainly because __________.
A.they give us a source of food

小题3:Why do people kill animals?
A.They kill animals for something they need.
B.They kill animals to raise some money.
C.Animals destroy their natural resources.
D.Animals create many problems.

Everyone knows about straight-A students. We see them frequently in TV situation comedies and in movies like Revenge(报复)of the Nerds. They get high grades, all right, but only by becoming dull laborers, their noses always stuck in a book. They are not good at social communication and look clumsy while doing sports.
How, then, do we account for Domenica Roman or Paul Melendres?
Roman is on the tennis team at Fairmont Senior High School. She also sings in the choral group, serves on the student council and is a member of the mathematics society. For two years she has maintained A’s in every subject. Melendres, a freshman at the University of New Mexico, was student-body president at Valley High School in Albuquerque. He played soccer and basketball well, exhibited at the science fair, and meanwhile worked as a reporter on a local television station. Being a speech giver at the graduation ceremony, he achieved straight A’s in his regular classes, plus bonus points for A’s in two college-level courses.
How do super-achievers like Roman and Melendres do it? Brains aren’t the only answer. “Top grades don’t always go to the brightest students, ” declares Herbert Walberg, a professor of education at the University of Illinois at Chicago, who has conducted major studies on super-achieving students. “Knowing how to make the most of your innate(天生的)abilities counts for more. Much more.”
In fact, Walberg says, students with high IQ sometimes don’t do as well as classmates with lower IQ. For them, learning comes too easily and they never find out how to get down.
Hard work isn’t the whole story, either. “It’s not how long you sit there with the books open, ” said one of the many-A students we interviewed. “It’s what you do while you’re sitting.” Indeed, some of these students actually put in fewer hours of homework time than their lower-scoring classmates.
The kids at the top of the class get there by mastering a few basic techniques that others can readily learn.
小题1:The underlined word “nerds” can probably be________ .
A.dull bookworms lacking sports and social skills
B.successful top students popular with their peers
C.students with certain learning difficulties
D.born leaders crazy about social activities
小题2:What can we conclude from the first paragraph?
A.Most TV programs and films are about straight-A students.
B.People have unfavorable impression on straight-A students.
C.Everyone knows about straight-A students from TV or films.
D.Straight-A students are well admired by people in the society.
小题3:Some students become super-achievers mainly because_________ .
A.they are born cleverer than others
B.they work longer hours at study
C.they make full use of their abilities
D.they know the shortcut to success
小题4:What will be talked about after the last paragraph?
A.The interviews with more students.
B.The role IQ plays in learning well.
C.The techniques to be better learners.
D.The achievements top students make.
小题5:What can we infer from the passage?
A.IQ is more important than hard work in study.
B.The brightest students can never get low grades.
C.Top students certainly achieve all-around developments.
D.Students with average IQ can become super-achievers.

Imagine that the genome (基因组) is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear(细胞核) that fits easily upon the head of a pin.
The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time.
While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules (分子).
The genome is a very clever book, because in the right condition it can both photocopy itself and read itself.
小题1:How do human genomes read according to the passage?___________
A.Only from left to right.
B.Only from right to left.
C.From both directions at the same time.
D.From one direction at a time.
小题2:We can learn from the passage that the human genome ________.
A.is as long as the River Danube
B.can be easily placed on the head of a pin
C.is coded with an alphabet of four letters
D.is smart enough to read and take photos of itself
小题3:It can be concluded that the passage is mainly written for ______.
A.specialists in the field
B.general readers
C.natural scientists
D.readers with professional knowledge
小题4:The real purpose of the author’s comparison of the genome to a book is _____.
A.to focus on the differences between the two
B.to lay emphasis on the similarities between the two
C.to simplify the concept of the human genome
D.to give an exact description of the human genome

For some people, the prospect of starting college, especially going away to school, is scary. It’s probably the first time that you’ll be totally responsible for your own schedule. What if you intend to go to college but just don’t feel ready to start yet-for whatever reason-and you don’t want to take on a full-time job after graduation? You might want to take a year off to pause and regroup. This practice is common in some countries, like the United Kingdom, where it’s called a “gapyear”.
Taking time off doesn’t mean you should ignore the idea of applying to college. In fact, you may want to consider making your college plans before you become involved in other things, especially if you’ll be travelling. Apply to schools and make your choice, then ask for a deferred admission. Rachel took a year off and worked in New York City between college and medical school. She says that she had to be extremely well organized about planning for medical school so she didn’t miss any of her deadlines. “Not only did I have to apply to schools and make plans to take my MCAT exams, I also had to make all my living arrangements and other plans for my year off!”
Even if you decide not to apply to college, it can be a great idea to take a year to do something you may not have an opportunity to do again. Lots of volunteer organizations would welcome your time and energy and would provide you with a wonderful learning experience. If you take a year off you will learn some great life skills-like living on a tight budget! If you take a year off you’ll pay your way while you are traveling or doing volunteer work.
小题1:What’s the best title of the passage?
A.Taking Time Off

A.asking for a year’s leave to rest at home
B.taking a year off to pause and regroup

A.it’s not easy to take a year off
B.it’s interesting to take a “gap year”
C.what taking time off is like

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live- in the middle of a modern city, or a faraway village the chances that you will be disturbed by jet planes , transistor radios, oil-powered engines, etc, are almost everywhere. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums (耳鼓). The noise level in some disco is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration , what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example ) may even help people to concentrate.

All Eskimos live most of their lives close to sea or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes, or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen (地衣) grow on the rocks, and where there is enough soil, grass, flowers, and even small bushes manage to live. No trees can grow on Eskimo land, so geographers sometimes call it the Arctic plains. There are some animals in Eskimo land, such as rabbits, which eat the plants. Other animals, like the white fox and the gray wolf, eat the rabbits. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce.
The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker.
Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes.
小题1:Which of the following statements is NOT true?
A.Eskimos do not usually eat wolves.
B.Eskimos like to chase one another.
C.Eskimos depend heavily on water.
D.Eskimos are meat-eaters.
小题2:What’s the meaning of the underlined words “pitch-black” in Paragraph 4?
A.Dark with a little light.
B.A little dark.
C.Not dark at all.
D.Extremely dark.
小题3:From the passage, we can infer all of the following EXCEPT that_______.
A.Eskimos are more likely to eat wolves in summer
B.Eskimo women are responsible for housework
C.meat is the main source of food for the Eskimo
D.hunting is an important part of Eskimo life

Today, traditional opinions about men still exist. A man has to be strong, brave, sports loving and manly. Anything less would not be considered manly. Sports such as football, basketball and boxing all tend (往往是) to be men’s sports. However, the dance of ballet is considered feminine because it requires nice movements. This tradition is shown in the movie, Billy Elliot.
Billy Elliot is a movie that protests against this traditional view of men. Billy Elliot is an eleven-year-old boy that has a natural talent for ballet dancing, but his father will not allow it. Billy’s father wants him to take up boxing and become stronger, but Billy goes against his father’s wishes and takes up ballet dancing. This difference of opinion makes Billy sad. What’s more, his friends also laugh at him.
After saving enough money, his father sends Billy to a weekly boxing course; however, Billy doesn’t enjoy boxing because he always loses in matches and is often hurt. His ballet teacher, Mrs. Wilkinson thinks that men or women should not be judged by the activities they like to do, so she tells Billy’s father that although he wants his son to make a good living, he should let his son do what he loves to do because he has a talent for it. When his father finally realizes the truth, Billy is surprised. In the end, with the help of his father, brother and all the people around him, Billy goes to the Royal Ballet Academy in London and becomes a very successful ballet dancer.
小题1:The underlined word “feminine” in the first paragraph most probably means ______
A.of menB.of childrenC.of womenD.of students
小题2:Why is Billy laughed at by other children?
A.He always loses in boxing matches.B.He isn’t strong.
C.He looks like a girl.D.He loves ballet.

A.His teacher encourages him to take up ballet dancing.
B.He does well in ballet dancing and boxing.
C.He does what his father wants him to do.
D.He has never taken up any men’s sports.
小题4:From Billy’s story, we can see that _______.
A.children should accept their parents’ opinions
B.we should try to fight against traditional opinions
C.men and women play different sports
D.parents should let their children do what they are interested in

Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
  1. Water
  A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
  2. Food
  It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
  3. Torch(手电筒) and spare batteries (电池)
  Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
  4. Clothes
  If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
小题1:Why should people prepare themselves for an earthquake?
A.Because earthquakes can be known before they happen.
B.Because earthquakes take place without warning.
C.Because earthquakes usually take place in the neighborhood.
D.Because it’s people’s daily work to prepare the earthquakes.
小题2:You should prepare all of the following except ______.
A.powdered milkB.fresh vegetablesC.dried fruitsD.canned juices
小题3:According to the article we know that ______.
A.we need to prepare some supplies only at home

C.after earthquakes you’d better use torch first but not matches
D.clothes are used to protect your head
小题4:If you live in a cold place, you should prepare _______.
