Now scientists believe that global warming affects hibernating animals, causing them to wake up earlier. While this may seem a little concern, it is in fact a serious environmental problem. The shortened hibernation period could actually lead to significant decreases in the population of several species.

Some of the first evidence of the problem came from Colorado, where researchers at the Rocky Mountain Biological Lab have been observing marmot (旱獭) hibernation behavior since the 1970s. In the early days of their studies, marmots generally hibernated several weeks into the month of May. Nowadays, however, temperatures in the area have risen by 2.5 degrees Fahrenheit, and the marmots wake up about a month earlier.

At least the marmots are still hibernating. Several other animals have not been hibernating at all recently. Brown bears in the Spanish Cantabrian Mountains did not hibernate last year. Chipmunks (花鼠) in the US and some snakes in Australia also skipped the hibernation period. The bears seem to have survived without losing many individuals. The chipmunks and snakes, however, were not so lucky. Many of the animals died of starvation during the winter.

The problem with animals waking up early, or skipping hibernation altogether, lies with the creatures' metabolism (新陈代谢). When the animals hibernate, their metabolism drops significantly. The animals' heart rate slows, and they require very little energy to live. When the animals awake in the spring, their metabolism returns to normal.

But while their metabolism may be as active as it was before hibernation, food sources aren't as available as they were before. A marmot may wake up when temperatures get warmer, thinking it's spring, but plants will not have got the amount of sun they need to grow. So until the plants grow, the marmots have no reliable food source.

Many scientists believe the problem will continue to get worse. For many biologists, that's a scary prospect. Terry Root, an animal expert at Stanford University, said, “I do think what we will be facing is the extinction of many species.”

1.What is the viewpoint of the writer?

A. Global warming will continue to get worse as time goes on.

B. Waking up early in spring may lead to the extinction of some animals.

C. Shortened hibernation will definitely decrease the population of animals.

D. Animals which do not hibernate die of starvation.

2.The writer sets the example of the marmot in order to .

A. indicate that global warming influences animals' hibernation

B. explain that the weather gets warmer and warmer now

C. show that the weather in the United States is quite different

D. say some animals do not hibernate now due to warm weather

3.Judging from recent observation, which of the following animals suffered the LEAST from shortened hibernation?

A. Brown bears.

B. Marmots.

C. Some snakes in Australia.

D. Chipmunks in the US.

4.Why can't marmots find enough food when they wake up?

A. Because there are too many marmots in the wild now.

B. Because more and more animal species skip hibernation now.

C. Because winter days end much earlier than before.

D. Because plants haven't received enough sunlight for spring growth.

By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends’ new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?

Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.

Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

Also, what you carelessly post on the Net can come back to trouble you. Revealing( 泄露) personal information on social sites can make users vulnerable(易受伤害的)to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

A. benefit users in various ways

B. offer professionals good chances

C. guide users to make right choices users to make right choices

D. help students finish their homework

2.Faced with problems caused by social media, some companies ________.

A. take legal action against the attackers

B. avoid posting embarrassing information

C. refuse to hire potential addicted employees

D. forbid the use of social networks during work time

3.The main purpose of this passage is to _________.

A. remind people to wisely use social media

B. share experiences in using social media

C. provide some advice on social problems

D. raise public awareness of social problems

________ parents say and do has a life-long effect on their children.

A That B Which C What D As

Every year in America, high-school students who want to go on to college take a national examination called the Scholastic Aptitude Test, or SAT in a shortened way. Their score is an important factor in determining which colleges will admit them. The Scholastic Aptitude Test measures one’s mathematical ability and use of the English language. Traditionally, the English part involved grammatical questions and paragraphs that test reading comprehension.

But the SAT folks have added a single question, to be answered in an essay, handwritten on the spot. That’s an interesting way to test writing ability, but content aside. Have you ever seen young people’s handwriting lately? Or anyone’s for that matter, in this age of computer keyboards? Students write numbers and sign their names on bank checks. They scribble class notes in what can generously be described as the written word.

Yet today’s kids are asked to write, thoughtfully and clearly, for several minutes on this SAT Test. Good luck to the text scorers who must work out difficultly the scrawl（潦草的笔迹）of young people who’ve been typing on computers since the age of three! Teachers insist that good handwriting can not only help one’s score on the SAT, but also, later on in life, impress potential employers. And don’t forget, we all have to use handwriting from time to time, as computers go down when the power goes out.

Then how to improve the handwriting? Well, with a few simple steps you can improve your handwriting.[来Position the pen. You should hold the pen between the forefinger and the thumb. You should then rest it near the first knuckle（指节）of the middle finger. The rest of your fingers should be curled（卷曲）under your hand and your hand should remain relaxed.

Evaluate your writing. What do you like and what don’t you like about the way you write? Make changes to your letters till you like how they look.

Take your time. Make sure that, while you are writing, you take your time. Speed can definitely make your writing terrible. If it is worth writing well, then take your time.

Practice. Practice it a lot; it’s not enough to do it once and hope for the best. It has to be something you work at to make great improvements.

1.At present, the SAT tests students on ______.

A．math, English, reading and writing

B．math, grammar, reading and handwriting

C．math, foreign language and writing

D．math, foreign language and handwriting

2.The underlined word “scribble” in Paragraph 2 probably means ______.

A．writing quickly and roughly

B．typing simply and correctly

C．painting clearly and neatly

D．describing properly and well

3.According to the text, good handwriting can ______.

A．help students pass the test

B．make a student more popular

C．show students’ ability

D．assist students in getting a job

4.Which of the following should you avoid when improving your handwriting?

A．Practicing writing a lot.

B．Writing as fast as you can.

C．Relaxing your hand when holding the pen.

D．Changing your letters till you like how they look.

5.The author mainly wants to tell us that ______.

A．writing seems to be very important in the SAT

B．those who will go to college have to take the SAT

C．students should practice handwriting more often

D．kids don’t know how to write in the computer age

Even if you are saying and doing the right things at your job and in your personal life, you could be making a bad impression on everyone with what you don’t say. That’s because much of our reactions to others are based on body language. If your body language is communicating a negative message, that’s the message you could be sending, regardless of what actual words come out of your mouth.

What are negative messages sent via body language? Things like having arms folded across your chest can show hostility(敌意). Lack of eye contact can indicate shiftiness(奸诈). An unsmiling face could communicate a variety of things, like anger, disappointment, or sadness, depending upon what other facial expressions are included.

Want to know what body language communicates? Watch a TV show or a movie with the sound off, and see how much you can figure out of the plot, or at least you can get a sense of what is going on.

However, many of the clues that indicate negativity could also be the result of nervousness or other issues. For example, somebody who doesn’t make eye contact could simply be nervous. The same goes with a not-so-warm hand-shake. Or, someone folding his arms could simply be more comfortable with the arms that way, not realizing what the arms’ position sends. Someone who doesn’t smile could be self-conscious about her teeth. At any rate, the person who sends off bad body language may not even realize that they’re doing it.

Unfortunately, some people who do recognize what body language communicates are scam(骗局) artists. They may have the firmest handshake, the shiniest smile, and make the greatest eye contact to convince others of their sincerity, because they know how much this nonverbal communications plays a part in communicating sincerity. Yet people fall for it, because their body language seems sincere.

But what if you’re in the opposite situation? If you’re not sure what your body language is communicating, ask a trusted friend for help. You can also concentrate on standing up straight and sitting up straight, if posture(姿势) is a problem. Practicing in front of a mirror can help you get rid of bad habits. Remember to smile and nod if needed. And try to learn how to relax. Before you know it, you will be sending more positive messages with your body language.

1.A serious face could indicate a lot of different information________.

A. especially anger and disappointment

B. together with the arms folded across

C. together with other facial expressions

D. depending on others’ facial expressions

2.The underlined expression “ fall for it ” ( paragraph 5) probably means _______.

A. be taken in B. be fully used

C. be used to it D. like it soon

3.A not-so-warm handshake may represent_______.

A. fear B. excitement

C. confidence D. nervousness

4.Which would be the best title for this passage?

A. Facial Expressions and Messages

B. Be Careful of False Body Language

C. Is Your Body Language Hurting You?

D. What Can Body Language Communicate?
