What makes a person a scientist？Does he have ways or tools of learning that are different from those of others？The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter(木匠).You will probably agree，too，that knowing how to investigate(调查)，how to discover information，is important to everyone. The scientist，however，goes one step further；he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.?
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different，any changes the scientist observes in a demonstration(实证)must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein，who developed the Theory of Relativity，arrived at this theory through mathematics. The accuracy(正确性)of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(计算)that may test his investigations.
小题1:What makes a scientist according to the passage？

A．The tools he uses.	B．His ways of learning.
C．The way he uses his tools.	D．The various tools he uses.

小题2:“...knowing how to investigate，how to discover information，is important to everyone.” The writer says this to show_______.

A．the importance of information

B．the difference between scientists and ordinary people

C．the importance of thinking

D．the difference between carpenters and ordinary people

小题3: A sound（合理的） scientific theory should be one that_______.

A．works under one set of conditions at one time and also works under the same conditions at other times

B．doesn’t allow any change even under different conditions

C．leave no room for improvement.

D．can be used for many purposes

小题4:What is the main idea of the passage？

A．Scientists are different from ordinary people.

B．The Theory of Relativity?.

C．Exactness is the core(核心)of science.

D．Exactness and way of using tools are the keys to making of a scientist.

小题1:C
小题2:C
小题3:A
小题4:D

试题分析：是什么品质成就了一名科学家呢？是他学习的方式还是学习的工具使他与众不同呢？答案是否定的。科学家之所以能成为科学家，不是因为他们使用的工具不同，而是因为他们使用工具的方式不同；此外作为一名科学家，他们提供的理论必须是精确严密的。
小题1:C细节理解题。由文章第一段It isn’t the tools a scientist uses but how he uses these tools which make him a scientist.可知一个人之所以能成为科学家不在于他所使用的工具，而在于他如何使用这些工具。故正确答案为C。
小题2:C推理判断题。根据句中的how可知如何去调查，如何去发现都需要运用人的思维能力，这些都是人们努力思考的结果，由此推断作者说这些话的目的是想说明思考的重要性，故C为正确选项。
小题3:A细节理解题。根据文章第二段What works under one set of conditions at one time must work under the same conditions at other times.可知科学理论指的是可以在一系列条件下面行得通的东西，必须在别的时候也可以在同样的条件下行得通，所以答案选A。
小题4:D主旨大意题。文章开头以设问方式提出中心What makes a person a scientist？然后在两段中分别介绍科学家所应该具有的品质，即如何使用工具和知识的严谨精确，由此可知D为正确选项。

Siri. The intelligent assistant that helps you get things done. All you have to do is ask.

Now you can use your voice to use your iPhone 4S. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.
Dual-core A5 chip: the most powerful iPhone ever.

Two cores in the A5 chip provide up to two times more power and up to seven times faster graphics. And you’ll feel the effects. iPhone 4S is quick and responsive, which makes all the difference when you’re launching apps, surfing the web, gaming, an doing just about everything.

It should be very clear that we live in a most spectacular（壮观的）time. It’s a time when information is of primary importance. It’s a time when new information technologies are fundamentally transforming the world in every aspect. Among the changes, which have come upon modern society, the ones in education are probably the most obvious and influential. New information technologies are accelerating changes in education, at the same time presenting revolutionary tools with the potential to make education more efficient and more effective than ever.
The application of new information technologies has remarkably promoted the process of education. Online learning is probably the best case in point. As is often the case with “technology”, online learning may appear to be horrible; it can sound like alphabet soup sometimes. Now let’s see whether you can understand all this. You can participate in CBT at a CLC via the convenience of IDL. What does it all mean? Let me translate: GBT—Computer-Based Training; CLC—Computer Learning Center; IDL—Interactive Distance Learning. Sound complicated? Not really. Online learning is much less complicated than it seems. Students can learn at any time, anywhere, at any speed. They can make their own learning schedules and follow their own paths to suit their lifestyles. In my university, every semester there’re several online courses available, which need no class meetings or paper materials. The only thing I have to do is just to get online regularly as I wish, and download necessary learning materials. Then everything I need to know about the course is only a click away.
But online learning is not perfect; it’s like the microwave oven: it does some things better, but it is not a complete replacement for the traditional model. The traditional classroom model for education and learning is hard to leave behind. Because humans are social creatures, there’re times when we need to see each other face-to-face for interactive learning. A social and personal connection often builds effective teams, solves problems, and inspires confidence. So one possible solution is to combine online learning with the old traditional classroom learning , which not only makes the learning process faster and cheaper, but also highlights the interactions between teachers and students.
The bottom line: the Internet is the most important educational tool in the information age and online learning will become a main part of every individual’s learning experience in the future. That’s exactly how we will move knowledge from the ones who have it to the ones who need it faster and cheaper, and that’s how we’re going to survive in the information age.
小题1:The most suitable title for the passage should be “___________.”

A．Education in the information age

B．Advantages and disadvantages of online learning

C．Online learning vs classroom learning

D．How to survive in the information age

小题2:In Paragraph 3 the microwave oven is mentioned as an example to indicate that_________.

A．online learning needs improving

B．online learning doesn’t suit everyone

C．online learning will exist alongside the traditional model

D．online learning is more advanced than the traditional model

小题3:Which of the following descriptions about online learning is NOT true according to the passage?

A．It is more efficient and effective.

B．It is convenient to both teachers and students.

C．It stresses interactions between teachers and students.

D．It is a cheaper way of learning.

小题4:It can be inferred from the passage that________.

A．not all the people are in favor of online learning

B．it is not easy to combine online learning with classroom learning

C．in the future all the courses will be available online

D．in a sense our survival in the world depends on online learning

About 35 percent of British adults sleep with teddy bears. Many more share a bed with a partner or spouse. Others still co - sleep, alongside children in a family bed.
But lying with your iPad? A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location. The living room took a close second place, at 63 percent, reports AdAge. com, and only 45 percent of respondents said they use their tablets on the go.
But bringing devices into the bedroom is a bad idea, if quality rest is your goal. One of the most important factors of sleepiness is darkness, which signals to the brain that it’s time to start speeding up production of the sleep - inducing hormone melatonin. But as the New York Times points out, in our modern world, we are exposed to light long after the sun sets. While any type of light can disturb your sleep, the blue wavelength light given off by cell phones, laptops, tablets and other gadgets is particularly troublesome. Research shows that this blue light causes alertness so decisively that it can actually be used to fight tiredness.
According to the National Sleep Foundation, 95 percent of Americans use some device, whether it’s a TV, laptop, cell phone or other products, within an hour of killing time. “Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep,” said Charles Czeisler, Ph. D. , M. D. , chief of the division of sleep medicine at Brigham and Women’s Hospital in Boston.
Instead, experts recommend turning off all devices an hour before bedtime and finding another method for relaxation, like reading a book, taking a warm bath or performing a series of calming yoga poses. It’s also a good idea to exercise and lay off the caffeine several hours before bedtime.
小题1: According to a recent survey, most tablet owners use their iPad ________.

A．in the living room	B．in the bedroom
C．in the office	D．on the move

小题2: What can we know from this passage?

A．The light from cell phones is harmful

B．Modern people have trouble falling asleep

C．Darkness can create a good sleeping environment

D．Blue light can prevent sleepiness decreasing

小题3:If we often play with a laptop just before sleep, we’ll be more likely to ________.

A．dream of it

B．stay awake

C．feel sleepy

D．become tired

Five Ways to Rock the Rest of the Semester
With exams around the corner, how can you possibly pack in one more English word, let alone the causes of the Cold War? Don’t worry. Here is our handy guide to help you
Power Down
So you stayed up too late last night reading Mockingjay for the fifth time. Oops! When you’re that fired, your schoolwork suffers. Instead of studying inefficiently while you are sleepy, allow yourself a 15-minute afterschool power nap. Studies show that even a few minutes of shut-eye can improve memory and concentration.
Take Notes
Not quite grasping that super complicated concept in your chemistry class? You may need to change the way you take notes. Instead of recording every word your teacher says, try using visual hints like pictures, symbols and word bubbles. You can even switch computer fonts or pen color for the important stuff.
Dream On
Your bed’s not just for zzz’s. Experts say it may be good to study in bed, too. Why? We’re able to absorb more right before bed because we’re less distracted and the new information stays in our minds as we sleep. So, slide into bed with a textbook or notes, read for 15 minutes, and then turn off the lights for some sweet and smart dreams.
Brain Food
You’re in the middle of a biology exam when your mind goes blank. You knew this stuff cold at home, but now you can’t tell a ribosome from a chloroplast. What’s going on? Your brain’s in need of some refueling. Have some snacks like apple slices or cheese before class, and have plenty of water, too. If your teacher doesn’t mind, pop in a piece of gum during an exam. Some scientists think the chewing increases the flow of oxygen to the brain.
Smart Move
Ugh! You’re taking an English test and you cannot remember the past participle of “understand”. What to do? Skip it. Test taking is all about timing, so don’t waste it on tricky questions. Move ahead and answer everything you know before returning to the ones you don’t. Chances are, once you get back to the toughies, you’ll recall the answer or at the very least, you’ll have a little more time to come up with one that works.
小题1:When taking notes, we can do all these except ______.

A．draw pictures

B．change the typeface

C．switch on the computer

D．colour the key points

小题2:According to the passage, _____.

A．it’s good to study under the covers for some time every day

B．you cannot skip the difficult questions and go on to the rest

C．you can have some snacks and drink enough water to refresh yourself in exams

D．when taking notes, you should record whatever the teacher says

小题3:What does the underlined phrase “knew this stuff cold” mean?

A．had no clue about it

B．were a cold fish

C．knew it was cold

D．were familiar with

小题4:You have been working on your essay for two hours and your eyes feel tired, you’d better

A．Power down

C．eat brain food

D．make a smart move

All too often, a choice that seems sustainable(可持续的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(环境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
小题1:What might directly cause the loss of the forest according to the text?

A．The growing demand for energy to make ethanol

B．The increasing carbon dioxide in the air

C．The greater need for farmland

D．The big change in weather.

小题2:The underlined word “it” in the second paragraph refers to “ ”

A．the energy benefit	B．the forest loss
C．climate change	D．burning ethanol

小题3:The author thinks that replacing gas with corn ethanol is .

A．impractical

B．acceptable

C．admirable

D．useless

小题4:What does the author mainly discuss in the text?

A．Technology	B．Sustainability
C．Ethanol energy	D．Environmental protection

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war.
But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化学制剂）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？
小题1:People will live under the ground because _________．

A．it’s neither hot nor cold there

B．they’ll be afraid of the war

C．there’ll be less space on the ground

D．they’ll make their life comfortable

小题2:Some countries try to build some places under the ground so that people will be able to live there _____．

A study shows that nearly ninety percent of teens report that they have tried alcohol. That’s an increase of 23 percent in just four years!
Each year, 1.1 billion cans of beer are drunk by students aged 15-19 years old. Beer is the most common alcoholic drink among teens—81 percent of the drinkers had tried it. Beer is followed by wine with 63 percent, hard liquor(烈酒) with 53 percent and wine coolers with 35 percent.
When the young people are asked why they drank, the most common answer is that drinking is “something to do”. If a teen’s parents drink alcohol, the teenager is more likely to start drinking at an early age. Also, tens see all of their friends drinking alcohol so they think it is the must-to-do thing. Peer pressure is probably the hardest thing teens have to deal with. What’s more, teens often drink alcohol because it makes them feel older and cooler.
Researchers asked 56,000 students about their drinking habits and grades, to see how drinking might affect their grades in school. The results seem to be clear. Students who got a C level or lower tend to use three times as much alcohol as those who got B’s or A’s.
Alcohol use can be deadly. About 8,100 young people are killed per year in alcohol-related accidents. Eight young people die per day as a result of a drunk-driving accident. Between 50 and 65 percent of all teen suicides (自杀) occur after the young people drink.
So you see, drinking the alcohol doesn’t always end up with a good time. The next time you try to push someone to drink or someone tries to push you to drink, please remember this. One drink can set the habit for life. Why not throw it away?
小题1:The reasons for teens’ drinking alcohol are mentioned EXCEPT that _______________.

A．they think it is cool to drink alcohol

B．their parents set a bad example to them

C．alcohol can make them happier

D．peer pressure plays an important role

小题2:What can we learn from paragraph 4?

A．Drinking alcohol makes students stupid.

B．Good students never try alcohol.

C．Drinking habits have something to do with IQ.

D．Students with poor grades tend to use more alcohol.

小题3:The passage was written mainly to ______________________.

A．show the bad effect of drinking alcohol

B．show how many teenagers drink alcohol

C．tell teenagers not to try alcohol

D．tell the reasons why teenagers drink alcohol.

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever.
