Do you to write with your left hand? If you do, you are one of the millions of “lefties” in the world. Why do some people use left hand more often than others? To understand left-handedness, it is necessary to look at the . The brain is divided into two hemispheres（半球）. The left hemisphere is the center of language and logical thinking. This is where they do their math problems and memorize words. However, the hemisphere controls how they understand ideas and they respond（作出反应） to the five senses—sight, hearing, , taste, and touch. The left hemisphere controls the right side of the body, the right hemisphere controls the left side. Both sides of the body receive the information from the brain because they are connected(联系). In right-handed people, the left hemisphere is stronger. In left-handed people, the right hemisphere is .
Lefties prefer not only the left hand but also the left . They would rather use the left foot to kick a ball because their whole body is “left-handed”.
From Newtown Albert Einstein, Wen Jiabao to Obama, Choplin to Zhao Benshan, many people are left-handed. Are you left-handed even though you are forced to write with your right hand? Don’t worry if you are, you are in good company.A. enjoy B. prefer C. want

A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds, they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is chemical.
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighboring plants. These chemical warnings can spread information about one plant’s disease or infestation(虫害), so other plants can protect themselves. But how plants receive and act on many of the information exactly is still mysterious.
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest(害虫). To start out, they grew plants in two separate plastic spaces connected by a tube(管子). One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed(暴露) to the pest. The results showed that plants near sick neighbors before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic come from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbors.
It is not a simple story, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
The underlined “traced” in the fourth paragraph probably means _________ here.
| A．reported | B．followed |
| C．doubted | D．developed |

Cycling—means riding a bike, is now popular among children from across the UK. Children like to go to school or go traveling for a short journey. It can help money in petrol(汽油) cost.
With petrol price rising(上涨), families in the UK are trying to ways to make the cost less in petrol. So the parents encourage(鼓励) their to ride bikes to school. They say a child keep cycling to school all the year round, a family can save about ￡300 in petrol cost.
Also, cycling to school is good for children’s . It can make them become healthier and their studies at school. “ cycling to school every day, we become fitter, smarter and better learners，”a student called Tommy said confidently.
“It’s great to see more people cycling, and I smile when I see a child on a bike. Many kids want to cycle, we should make it easy and safe for them to get around by bike and keep healthy，”another student, Mark said.

What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.
Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products（产品）. Dell, Hewlett-Packard and other companies now also take back some old computers.
In some countries, laws（法规）are being passed, too. Computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.
The computers then go to schools, charities（慈善团体）and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too.What do many people do with old computers?
| A．They repair them. | B．They sell them. |
| C．They send them to others. | D．They stop using them. |

| A．Help the computer companies to collect them. |
| B．Repair and send them to those who need them. |

IQ（intelligence quotient智商）is a score that shows a person’s level of intelligence.
People used to believe that some people are born with a high IQ and some aren’t.
32 , a study by scientist at University College London has challenged（挑战）this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant（不变的）score.
The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.
Scientists found big changes in the IQ scores between 2008 and 2004. Some 33 and some fell 34 as many as 21 points.
To test whether these scores were meaningful, the scientists compared them with results from brain scans（扫描）. They found that the IQ changes matched changes in the structure（结构）of the subjects’ brains. “A change in 20 points is a huge 35 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a 36 person. The team has not found a clear cause for these changes. However, they say it is 37 that education plays a role in changing IQ.
“Here we have shown that children’s 38 is likely to be still developing, ” says Price. “We have to be careful not to write off 39 performers at an early stage. In fact, their IQ may improve in a few more years. ”
