It seems hard to watch someone yawn（打哈欠） and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force.
Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don’t develop this deeply rooted behavior until around age four, the study found. Kids with autism (自閉癥) are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect.
"Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did.
"The fact that autistic kids don’t do it might mean they’re really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others’," she added. "Autistic people never seem to understand that."
Like infectious （有感染力的）laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group.
小題1:What does the new study suggest, according to the first two paragraphs?
A．Yawning is a form of communication.
B．It is easy to stop yawning when you see others yawn.
C．Children follow others in yawning just after they are born.
D．Yawning has some mysterious force which is related to God.
小題2:According to Molly Helt, _________.
A．humans differ from animals because they communicate with others
B．yawning is a kind of emotional connection among humans
C．emotions are infectious, but yawning is not
D．yawning helps clear ears on planes
小題3:Which of the following is NOT true about yawning?
A．It is natural to yawn back if people around you yawn.
B．Some kids are too young to yawn after others.
C．Yawning can be used to test children’s development.
D．Kids with autism yawn easily when others yawn.
小題4:The author implies in the last paragraph that ________.
A．yawning is different from infectious laughter and crying in theory
B．it is bad manners to yawn on some social occasions
C．the more you yawn, the happier you will be
D．yawning can make people feel relaxed

小題1:A
小題2:B
小題3:D
小題4:D

Don’t you just love ice skating every winter？I am sure，that since winter is approaching，your skates are set to come out，just waiting to be used.Impress your friends with your new trick on how to ice­skate backwards with the help of these tips.Skating backwards on ice is a bit difficult but once you master the basic，there’s nothing like it.Follow the steps given below and you will be able to skate backwards in no time.
Stand Straight
The first thing that you need to do is，stand straight.If you feel that you are falling backwards，then just put your chin(下巴) up and slightly bend your knees.Don’t worry；this happens to all.
Confidence Is What You Need
The most important step while learning how to skate backwards，is having enough confidence in yourself and in what you are doing.How can you achieve this？By practice.Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort.But before you do that，make sure that the place where you are practicing is free from any kind of debris(碎片) because otherwise，you could land up in the hospital due to some accident.While going backwards，just get used to the feeling of moving backwards.One of the important ice skating tips and techniques is that if you feel that you are losing your balance，then scissor(做剪式運動) your skates.Keep practicing this till you are confident about it.
Maintain Speed
Confident now？Great！Now the next step is to maintain your speed.While rolling in a straight line with one skate，with the other try sculling(劃槳)，that is，keep pushing yourself backwards with an outwards stroke(滑動)．Now bring the skate which you were using to scull，and then again，repeat the same process.Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling.Now，try the same thing using the other foot.Again keep doing this till you are confident enough.
Increase Your Speed Now
Once you are confident that you can scull with either foot，the next thing that you have to do is increase your speed.Try some of your own tricks now.Scull with either foot or with both at the same time.
Scull and Be Aware
While you keep one foot straight，keep sculling with the other.You can do that simultaneously with both feet.Concentrate on what you are doing but don’t get so involved，that you don’t see where you are going.If you are not watching your back，you might just bang against something or someone.
小題1:According to the text confidence comes from ______.
A．high speedB．strict coaches
C．constant exerciseD．good techniques
小題2:Which is the right order of ice­skating backwards?
a．Increasing your speed.
b．Being able to scull with one foot.
c．Being about to stand straight.
d．Trying some different tricks.
A．c→a→d→bB．c→b→d→a
C．a(chǎn)→c→b→dD．c→b→a→d
小題3:In order to keep balance when skating backwards you should ________.
A．skate in a scissor gesture
B．use both your feet to scull
C．skate forward first and then backward
D．put most of your weight on the skate with which you are sculling
小題4:The purpose of the text is ________.
A．to compare different ways of ice­skating backwards
B．to introduce the culture of ice­skating backwards
C．to explain advantages of ice­skating backwards
D．to offer some advice on ice­skating backwards

Blind imitation (模仿)is self-destruction. To those who do not recognize their unique worth. Imitation appears attractive: to those who know their strength. Imitation is unacceptable.
In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes (菜譜) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.
In daily life, imitation can hurt us if we subconsciously (下意識地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.
In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.
Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.
Syudy your role models, accept the gifts they have given, and leave behind what does not server. Then you can say,” I stand on the shoulders of my ancestors” tragedies and tory, and know that they are cheering on.
小題1: Imitation proves useful when you        .
A．know you are unique
B．lose the balance of life
C．begin to learn something new
D．get tired of routine practice
小題2:  To avoid the bad result of imitation, we should________.
A．forget daily fear and pain
B．choose the right example
C．a(chǎn)sk others for decisions
D．stay away from stars
小題3:.Acording to the author. The world moves on because of those who are          .
A．desperate to intruence others with their knowledge
B．ready to turn their original ideas into reality
C．eager to discover what their ancestors did
D．willing to accept others’ ideas
小題4: The trouble a creator faces is          .
A．the lack of strong motivation
B．the absence of practical ideas
C．how to search for more materials
D．how to use imagination creatively
小題5: What is the author’s purpose in writing this passage?
A．To highlight the importance of creatively.
B．To criticize the characters of role models.
C．To compare imitation with creation.
D．To explain the meaning of success.

With the crazy smog going on in China, businessmen are now ready to grope for your wallet. “Smog economy” is stimulating a shopping spree on certain products against the terrible weather. Now let’s see what we have on the list to help us through the crisis.
1. Masks
Well, I would say you had better stay indoors to save your lives. PM 2.5 just surged up to 750 in Beijing recently. 3M just sold 220,000 masks of a kind. No.1 best-selling products!
2. Air purifiers
This kind of products is rarely seen in Chinese households in the past. They have become a necessity now. I do like these little gadgets, but they are just too expensive.
3. Oxygen inhalers
I didn’t realize oxygen inhalers also get a cut in the smog economy. As a matter of fact, your oxygen uptake has nothing to with relieving (減輕) the impact of smog. It might even lead to oxygen poisoning when you inhale too much oxygen. So don’t get greedy.
4. Salt lamps
Compared to oxygen inhalers, salt lamps are even worse. Some stores are selling the products at several hundred yuan, saying that they can release negative ions(離子), reduce radiation levels and purify the air. The lamps mainly contain sodium chloride. The boiling point of sodium is about 800 degrees centigrade and that of candle is 500. So how on earth can negative ions be released at only 500 degrees?
5. Plants that absorb smog
Yeah, right. Plants Vs Smog. It is scientifically justified (證明) that some plants do absorb pollutants from the air. Money plants and calla lilies are among the best-sellers in the market. Even if they don’t work, it’s good to have some plants in the house anyway.
小題1:According to the passage, smog _______.
A．give some economic chances to businessmen
B．is very bad to economy
C．makes some crisis come out
D．have nothing to do with the economy
小題2:What is the meaning of the underlined word?
A．Giving up shopping.B．Feeling down in shopping.
C．Having a lot to buy.D．Buying something enthusiastically.
小題3:Salt lamps are useless, because_______.
A．it may cause poisoning
B．it actually can’t release the negative ions
C．it reduces radiation level and makes the air dirty
D．the prize is very high
小題4:How many ways does the author think are useful?
A．2.B．3.C．4.D．5.

Today’s youth seem content to take the easy route and enjoy the ride of life. When tough situations arise, they often get annoyed and complain. How you live your teen years will have a profound influence on the rest of your life.
You must learn to use your time wisely. You may not see it now, but developing leadership characteristics at a young age is very important. As we get older, it becomes harder to overcome bad habits and replace them with good ones. Possessing leadership    qualities is essential, both in this life and in the world to come. There are certain qualities that one needs to develop in order to become a leader: justice, judgment, dependability, initiative, decisiveness, tact, integrity, enthusiasm, poise, unselfishness, courage, knowledge and loyalty. You may recognize these as good qualities to have, without realizing how they apply to leadership. The more these qualities are part of your nature, the more productive and enjoyable your life will be. All of these are qualities that one must possess to one degree or another.
Contrary to popular opinion, leadership is something   that is learned. No one is born a leader. We are all capable of exhibiting the   leadership qualities mentioned above — some just choose not to. Of course, not  veryone can be the “top dog”, let alone all the time. However, everyone does have the capacity to lead in some way — but action is required! Understand that learning is a fact of life—learning to ride a bike, learning to drive, learning to type, learning mathematics, etc. All of these activities require action. While we are born with many different abilities, if we do not use and develop them, those abilities will never come to fruition. Youth is an excellent time to start developing leadership characteristics. Take the time to study each one in detail. Put them into practice as you interact with other people. Determine which areas you are weak in, striving to always improve. Observe the leaders, and how     they handle situations and  carry themselves. Also, study the lives of great leaders. The results will serve you in this life — and beyond!
小題1:The purpose of the second paragraph is to show that    .
A．one must overcome bad habits at first
B．a(chǎn)ll leaders have the mentioned leadership characteristics
C．the earlier and the more you develop leadership characteristics, the better it is
D．one must know how to apply the mentioned leadership characteristics first
小題2:Not everyone can be a leader because______.
A．they are lazyB．they don’t learn
C．they don’t have the qualities mentionedD．they don’t develop their abilities
小題3:What does the underlined sentence mean?
A．Everyone can be a leader all the time.
B．Everyone can not be a leader all the time.
C．Nobody can be a top leader all the time.
D．Nobody can not be a leader all the time.
小題4:What is the best title for this passage?
A．Learn to be a leader.B．Everyone can be a leader.
C．Leadership characteristics.D．Leadership is something that is learned.

Eyeglasses correct many different types of sight problems, including nearsightedness, farsightedness or astigmatism (散光). Trying to understand those different numbers on an eyeglass prescription (驗光單) requires understanding the measurements optometrists (驗光師) use when fitting you for corrective lenses (鏡片).

Diopters (屈光度)
The numbers on your prescription are given in diopters, whose short form is "D". It is used to measure the focusing power, or amount of correction.
O.S. and O.D.
Optometrists use the Latin short form O.S. and O.D. to distinguish between your eyes. O.S. refers to your left eye, while O.D. refers to the right eye.
Generally, your prescription will show a number for O.S. and O.D. (given in diopters). The farther this number is on a number line from zero, the more correction your eyeglasses should provide. A plus sign means the eye is farsighted, while a minus sign means the eye is nearsighted.
Spherical Value
This plus or minus number for each eye is called the spherical value, or the degree of nearsightedness or farsightedness you have. Its short form is "S."
Cylinder
If you have an astigmatism, the optometrist will also measure its degree. The higher the number (given in diopters) marked as the cylinder of astigmatism, (its short form is "C"), the more astigmatism there is in that eye.
Axis
An astigmatism is also measured in terms of its axis, which is a number between 0 and 180. The axis of the astigmatism does not relate to the amount of cylinder, just the location of the irregularity of the astigmatism on that particular eye.
小題1:According to the first paragraph, various sight problems ______.
A．should be understood by the patients
B．can be avoided by wearing corrective lenses
C．should be tested by different optometrists
D．can be corrected by wearing eyeglasses
小題2:If you need a pair of corrective lenses, the optometrist will first value the numbers of ______.
A．DioptersB．Spherical ValueC．CylinderD．Axis
小題3:From the prescription above we can learn that Li Hua ______.
A．is farsightedB．is nearsighted
C．has no astigmatismD．is normal in sight
小題4:The text is probably taken from ______.
A．a(chǎn)n education reportB．a(chǎn) school bulletin
C．a(chǎn) local newspaperD．a(chǎn)n encyclopedia (百科全書)

“I’m a little worried about my future．”said Dustin Hoffman in The Graduate．He should be so lucky．All he had to worry about was whether to have an affair with Mrs. Robinson．In the sixties，that was the total sum of post-graduation anxiety．
Hoffman’s modem peers are not so fortunate．The Mrs. Robinsons aren’t sitting around at home any more．They are out in the workplace，doing the high-powered jobs the graduates want，but cannot get．For those fresh out of university，desperate for work but unable to get it，there is a big imbalance between supply and demand．And there is no narrowing of the gap in sight．
Parents feel as badly let down as the young people themselves．Middle-class families see their graduate offspring on the dole (救濟金) queue and wonder why they bothered paying school fees．Working-class families feel an even keener sense of disappointment．For many such families，getting a child into university was the fulfillment of a lifelong dream．It was proof that they were living in a dynamic，economically successful country．That dream does not seem so rosy now．Graduate unemployment is not，ultimately，a political problem．Job-creation for graduates is very low down in the government’s schedule．If David Cameron’s Conservatives (保守黨) had a brilliant idea for guaranteeing every graduate a well-paid job，they would have presented it by now．It is a social problem，though a more deep-seated social problem than people perhaps realize．
小題1:The author begins with the lines from The Graduate in order to __________ ．
A．support the fact that more women are working now
B．show that few graduates started working right after graduation
C．demonstrate that there were much fewer graduates than now
