Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the
process of aging could be slowed down.With a team of colleagues at Tokyo National University,
he set about measuring brain volumes of a thousand people of different ages and jobs.
Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."wThe team of doctors wanted to find out ______.
| A.why certain people age sooner than others | B.how to make people live much longer |
| C.the size of certain people's brains | D.the people with more intelligence |
On what are their research findings based?
| A.A survey of farmers in northern Japan. |
| B.Tests performed on a thousand old people. |
| C.The study of brain volumes of different people. |
| D.The latest development of computer technology. |
Matsuzawa thinks that _______.
| A.our brains grow as we grow older |
| B.the front section of the brain does not shrink |
| C.sixty-year-old people have better brains than thirty-year-olds |
| D.the contraction of brains is connected with brain exercise |
According to the passage, which people seem to age slower than others?
| A.Farmers. | B.Lawyers. | C.Government workers. | D.Shop assistants.w |

In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn’t want to copy the USA’s example. We’re planting more and more trees. We’ve built the " Great Green Wall" of trees across northern part of our country.The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed.

Looking back on China’s road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years.
After China’s first satellite into the Earth’s orbit in 1970 came four flights of unmanned Shenzhou missions(飞行) from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China’s second human spaceflight, was launched, with a crew of two astronauts. What’s more, the landmark(里程碑)spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration.
Meanwhile, China’s moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world’s first man-made satellite, China’s first circumlunar(绕月的)satellite Chang’e 1 took off on Oct.24, 2007, which became the third landmark in China’s space achievements after the above-mentioned manned flights. Chang’e 1 was expected to fulfill four scientific goals, one of which was to expore mineral elements on the moon, especially those not existent on Earth. It’s said that the lunar regolith(月壤) is abundant in helium-3, a clean fuel that may support the Earth’s energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the launching of Chang’e 2, China’s 2nd unmanned lunar probe(勘探),marking another step forward in moon exp
loration. This time the aim is to test the key techniques of Chang’e 3 and Chang’e 4, as a preparation for a soft lunar landing in the future.

The UK has a wellrespected higher education system and some of the top universities and research i
nstitutions in the world. But to those who are new to it all, sometimes it can be confusing.
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.
However, having just left the comfort of home and all your friends behind, the prospect(前景) of meeting lots of strangers in big halls can be nervewracking(令人头痛的). Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here are some top advice from past students on how to survive Freshers’ Week:
●Learn rules. Make sure you know British social manners. Have a few wine glasses and snacks handy for your housemates and friends.
●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
●Be sociable. The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves their room.
●Bring a doorstop. Keep your door op
en when you’re in and that sends positive messages to your neighbors that you’re friendly.
