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.

小題1:A
小題2:D
小題3:B
小題4:B

Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虛擬水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.   
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products
小題1:What is the best title for the passage?
A．Crops and Virtual WaterB．Import and Export of Water
C．Benefits of Virtual WaterD．Water’s worldwide travels
小題2:The first paragraph is intended to talk about__________.
A．how water flows
B．what virtual water is
C．where virtual water exists
D．why water is imported and exported
小題3:The example of a sugary soft drink in Paragraph 3 is given to show_________.
A．how drinks are madeB．how virtual water is used
C．how virtual water is exportedD．how drinks are shipped
小題4:In which countries does most part of virtual water come from outside?
A．lsrael and AmericaB．America and the Netherlands
C．China and the United KingdomD．Kuwait and the Netherlands
小題5:The passage is most probably a_________.
A．science news reportB．book review
C．newspaper advertisement D．science fiction story

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

The interview has been going on for about 20 minutes and everything seems to be going well．Then, suddenly, the interviewer asks an unexpected question, “Which is more important, law or love?”
Job applicants in the West increasingly find themselves asked strange questions like this．And the signs are that this is beginning to happen in China．
Employers want people who are skilled, enthusiastic and devoted．So these are the qualities that any reasonably intelligent job applicant will try to show no matter what his or her actual feelings are．In response, employers are increasingly using the questions which try and show the applicant’s true personality．
The question in the first paragraph comes from a test called the Kiersey Temperament Sorter．It is an attempt to discover how people solve problems, rather than what they know．This is often called aptitude (天資) test．
According to Mark Baldwin of Alliance, many job applicants in China are finding this type of questions difficult．“When a Chinese fills out an aptitude test, he or she will think there is a right answer but they may fail because they try to guess what the examiner wants to see．”
This is sometimes called the prisoner’s dilemma(窘境)．Applicants are trying to act cleverly in their own interest, but they fail because they don’t understand what the interviewer is looking for．Remember that in an aptitude test, the correct answer is the honest answer．
小題1:What is the purpose of the passage?
A．To give a piece of advice to job interviewees．
B．To tell you how to deal with job interviews．
C．To advise you how to find a good job．
D．To describe an aptitude test．
小題2:According to the writer, in an aptitude test, Chinese job applicants should ________.
A．not tell the truth
B．offer a complete answer
C．learn to tell what they really think
D．find out what the examiner wants to know
小題3:From the passage we know that ________．
A．job applicants are always trying to show their actual feelings
B．a(chǎn)pplicants should not act as cleverly as possible
C．more Chinese applicants fail to find a job
D．a(chǎn)ptitude test is becoming world-wide popular

You may think that sailing is a difficult sport, but it is really not hard to learn it．You do not need to be strong．But you need to be quick．And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat．The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind．This means the wind and the boat are going in the same direction．Then you must always keep the sail outside the boat．It should be at a 90° angle (角度) to the boat．Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat．In this case, you must keep the sail half way outside the boat．It should be at a 45° angle to the boat．It needs to be out far enough to catch the wind, but it shouldn't flap (擺動(dòng))．It shouldn't look like a flag on a flagpole．If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible．If you try, the sail will flap and the boat will stop．You may want to go in that direction．It is possible, but you can't go in a straight line．You must go first in one direction and then in another．This is called tacking．When you are tacking, you must always keep the sail inside the boat.
小題1:What should you consider first while sailing?
A．Sailors' strength. B．Wave levels.
C．Size of sails. D．Wind directions.
小題2:What does the word “It” underlined in Paragraph 4 refer to?
A．The boat. B．The sail.
C．The wind. D．The angle.
小題3:What do you have to do when sailing against the wind?
A．Move in a straight line. B．Allow the sail to flap.
C．Lower the sail. D．Tack the boat.
小題4:Where can you probably find the text?
A．In a popular magazine. B．In a tourist guidebook.
C．In a physics textbook. D．In an official report.
