It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
　　The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
　　And so we could go on adding more examples until in despair(絕望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
小題1:The first paragraph tells us that _____.
A．a(chǎn)ll living things in nature depend on each other
B．everything in nature can’t exist without the help of man
C．man has known the importance of the balance of nature for a long time
D．no living thing can live naturally
小題2:In the second paragraph the examples given are used to prove that _____.
A．a(chǎn)ll forms of life belong to a system in which all the parts can be changed for one another
B．it is only during the last few years that man has generally known the balance of nature
C．there are some living things which can exist by themselves without change
D．we can’t change one form of life without destroying the balance of nature
小題3:The last paragraph suggests that in order to get his immediate benefits(利益) _____.
A．man is always anxious to control his activities within limits
B．man is always too eager in planning for distant future
C．man often fails to think about their future results of his action
D．man often feels that he will have to give up in despair
小題4:Which of the following is true according to the passage?
A．Cutting down woods does little harm to human beings.
B．Man has to pay much more attention to the future results of his present action.
C．Oxygen comes from forests.
D．The passage tells us to try our best to get as much as possible immediately.

Everyone is at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction (網(wǎng)上拍賣).
Buying for beginners: Sign up on www. ebay. co. uk. Most items（e.g. tables, computers, and books）ready for auction will come with a picture and a short description; others may be marked with “ Buy It Now ” and have a fixed price. You can buy these right away.
If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids（出價）for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish you get an email telling you whether you have won the item.
How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card (信用卡).
Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
The big things in life: It’s easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men. Check the ways of delivery before you bid.
小題1:What is the passage mainly about?
A．How to make payment online.
B．Ways of using delivery online.
C．Advantages of an online-auction system.
D．How to use an online-auction system.
小題2:After bidding for an item, a buyer __________.
A．will get what he wants in ten days
B．should make payment immediately
C．has chances to make higher bids
D．may check its picture and description
小題3:The easiest way of making payment mentioned in the passage is __________.
A．through an online payment system
B．through a local banking system
C．by sending the money to the seller
D．by paying the deliveryman directly

With the Tesla Roadster and other plug­in (插入式) electric vehicles hitting the road，demand is growing for accessible refueling points to recharge them. Carbon Day Automotive, a Chicago­based company，has now demonstrated a solar­powered recharging point, known as the Solar Plug­In Station，which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.
The Solar Plug­In Station has gone on show in Chicago as part of the city’s bid to host the 2016 Olympic Games. According to Carbon Day Automotive，the Solar Plug­In Station on show in Chicago is part of the vital infrastructure(基礎(chǔ)設(shè)施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.
These solar­powered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollution­free solar cell, the CO2 emissions are reduced to zero.
“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations，marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar Plug­In Station consists of giant solar panels (電池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack，ready for everyday refueling.
“Without these stations it would be like driving around in a traditional car without the availability of gas stations，” says Scott Emalfarb，CEO at Carbon Day.“The day of true plug­in electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate them.”
小題1:The Solar Plug­In Station is used as part of the bid to host the Olympics mainly because ________.

It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept (概念) of “how much”.
Previous research had suggested that very young babies can tell when the number of objects (物體) in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected.
Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors (傳感器). The babies watched a series of images on a computer screen. They showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn’t change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies’ brains responded with a specific pattern of electrical signals, which would be recorded by sensors.
By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies’ brains are doing more than just reacting to a change in what they’re seeing – they actually seem to be able to tell number changes from other types of changes.
Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting (減), multiplying, and dividing, their brains seem to be preparing for a time when they finally will.
小題1:Why were hats with sensors used in the study?
A．To record the images on the computer screen.
B．To remind babies of the changes of numbers.
C．To record the electrical activity of each baby’s brain.
D．To help babies concentrate on the computer screen.
小題2:What does the underlined word “They” in the third paragraph refer to?
A．Babies involved in the study.
B．Sensors worn by the babies.
C．Numbers marked on the objects.
D．Images shown on the computer screen.
小題3:Which part of the brain is responsible for responding to the changes of numbers?
A．The top.
B．The left side.
C．The lower and the right side.
D．The upper and the left side.
小題4:The last paragraph mainly implies that           .
A．babies are in fact cleverer than they are thought
B．it is impossible to understand human brain completely
C．numbers play the most important part in people’s lives
D．the ability of babies remain a mystery to scientists
小題5:The purpose of the study is to prove that          .
A．math skills should be developed as early as possible
B．numbers are easier for babies to judge than images
C．babies really do have some sense of numbers
D．babies can react differently to what they see

Scientists at Harvard University and Bates College find female chimpanzees (黑猩猩) appear to treat sticks as dolls, carrying them around until they have children of their own. Young males engage in such behavior much less frequently.
The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the journal Current Biology, provides the first evidence of a wild non­human species playing with dolls, as well as the first known sex difference in a wild animal’s choice of playthings.
The two researchers say their work adds to a growing body of evidence that human children are probably born with their own ideas of how they want to behave, rather than simply mirroring other girls who play with dolls and boys who play with trucks. Doll play among humans could have its origins in object—carrying by earlier apes (猿類), they say, suggesting that toy selection is probably not due entirely to socialization.
“In humans, there are obvious sex differences in children’s toy play, and these are remarkably similar across cultures,” says Kahlenberg. “While socialization by elders and peers has been the primary explanation, our work suggests that biology may also have an important role to play in activity preferences.”
In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg and Wrangham counted more than 100 examples of stick­carrying. Some young chimpanzees carried sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. “We have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated them rather like dolls, we wanted to know if in general this behavior tended to represent something like playing with dolls,” says Wrangham, a Professor at Harvard. “If the doll hypothesis (假設(shè)) was right, we thought that females should carry sticks more than males do, and that the chimpanzees should stop carrying sticks when they had their first child. We have now watched enough young chimpanzees to prove both points.”
小題1:What does a female chimpanzee do with sticks?
A．She gives them to her child to play with.
B．She treats them as dolls.
C．She makes useful tools from them.
D．She treats them as weapons.
小題2: What causes the different toy selection of chimpanzees, according to the passage?
A．Sex difference.B．Socialization.
C．Environment. D．Cultural difference.
小題3:We can infer from the fourth paragraph that ________.
A．socialization has nothing to do with human’s choice of playthings
B．sex difference is the only factor in human’s choice of playthings
C．the biology factor may also influence toy choice
D．people choose different toys in different cultures
小題4:It can be concluded from the passage that ________.
A．both humans and chimpanzees choose their playthings due to sex difference
B．different factors cause humans and chimpanzees to choose different playthings
C．only female chimpanzees have playthings
D．chimpanzees usually choose playthings for their children
