To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn’t a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater.
“Planting tress is one way, but it isn’t that simple. It doesn’t solve the basic issue of water resources,” says Wu Bo, a professor. “We need to calculate how much water the trees will absorb, or else it could have a negative effect.”
Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields(产量) using flood irrigation and earns a good income for his family.
Other farmers haven’t stuck it out(坚持到底): about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return.
Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight.
“With enough water, this problem can be solved,” Lu says. “We can plant trees and grass, and they will grow bigger. That will stop the desert.”
Experts say that farmers could switch to drip irrigation (滴灌)to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to “Save Water, Protect the Environment”.The negative effect of planting trees in deserts is that __________.
A.it can make groundwater become less |
B.it can prevent the sand moving freely |
C.it can stop crops growing well |
D.it can get the soil to become poor |
Why did Mr. Lu NOT accept the idea of relocation?
A.Because the plan of relocation will cost him much money. |
B.Because his family had trouble moving away. |
C.Because he was reluctant to give up his land. |
D.Because he would rather stay than fight against the deserts. |
What can we infer from the passage?
A.The deserts drive more and more people to leave their homes for their lives. |
B.People have no means to fight against the land becoming desert. |
C.Water is the biggest barrier for people to stop the desert. |
D.Planting trees cannot solve the problem of desertification of farmland. |
What advice is given by experts to save water?
A.To plant more trees. |
B.To build greenhouses. |
C.To change crops. |
D.To use drip irrigation. |

Students throughout the world spend their money in different ways. A detailed study on student spending indicated that young people's spending habits have changed greatly over the past few years. The study also says that the change is about the same around the world, however. Here are some examples of popular student spending habits---both healthy and also unhealthy---around the world today.
Students these days have too much brand awareness, so their spending on clothes is now quite high. On average, students buy one or two complete sets of new clothes each month, and this makes their total spending higher.
Student spending shows quite an up-and-down pattern as they get older. Students spend a lot more money in high school than before their high school years because when they enter high school, their exposure (接触到) to branded goods increases. As the students get close to graduation, their expenses start to go down. This is the time when they have to become more responsible about money and start to understand its importance.
Students also spend a lot more on entertainment than their parents did when they were young, because of the easy access to entertainment these days. Shopping is considered to be quite entertaining because of all the different forms of amusement presented by shopping malls. These attract students to buy things.
Student spending on food hasn't increased much, but there has been a marked increase in the use of alcohol. There are several more places in which students can drink now. The culture of having parties has also grown a lot among students too, and students usually end up spending a lot on alcohol in such places.
This is not such a bad situation, actually. The study indicates that although student spending has shot through the roof, at the same time, they are financially much stronger today than they were in the past. This is compensation (补偿,回报), and probably it is just another branch of the life that we are living in this speedily advancing world.
1. What is the passage mainly about?
A. Unhealthy student spending habits. B. Why student spending is changing.
C. How a student should spend money. D. A study on student spending.
2. Why do students spend less money just before graduation?
A. They see fewer products.
B. They are more conscious of the value of money.
C. They have no time to entertain themselves or go shopping.
D. Their spending on clothing goes down.
3. What can we learn from the passage?
A. Student spending habits are becoming worse and worse.
B. Today's students spend more money on entertainment than on clothing.
C. Today's students are better at earning money than their parents.
D. Student spending on food has increased the least.
4. Which of the following best shows the structure of the passage?
①Paragraph 1; ②="Paragraph" 2; ③="Paragraph" 3; ④="Paragraph" 4;
⑤="Paragraph" 5; ⑥="Paragraph" 6;
This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics(数据) on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors(肿瘤), is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is just to be prepared.

A.To argue that high school students are easily persuaded.
B.To prove what is necessary to us might be dangerous.
C.To show the danger of reporting only part of the information.
D.To warn us of the harmful substance around us.

D.We should learn to think critically and look at problems from all sides.
People tend to think of computers as isolated machines, working away all by themselves. Some personal computers do without an outside link, like someone's secret cabin in the woods. But just as most of homes are tied to a community by streets, bus routes and electric lines, computers that exchange intelligence are part of a community local, national and even global network joined by telephone connections.
The computer network is a creation of the electric age, but it is based on old-fashioned trust. It cannot work without trust. A rogue (流氓) loose in a computer system called hacker is worse than a thief entering your house. He could go through anyone's electronic mail or add to, change or get rid of anything in the information stored in the computer's memory. He could even take control of the entire system by inserting his own instructions in the software that runs it. He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there.
Hacking, our electronic-age term for computer break-in is more and more in the news, intelligent kids vandalizing(破坏)university records, even pranking (恶作剧) about in supposedly safeguarded systems. To those who understand how computer networks are increasingly regulating life in the late 20th century, these are not laughing matters. A potential for disaster is building: A dissatisfied former insurance-company employee wipes out information from some files; A student sends out a "virus", a secret and destructive command, over a national network. The virus copies itself at lightning speed, jamming the entire network thousands of academic, commercial and government computer systems. Such disastrous cases have already occurred. Now exists the possibility of terrorism by computer. Destroying a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic. Yet neither business nor government has done enough to strengthen its defenses against attack. For one thing, such defenses are expensive; for another, they may interrupt communication, the main reason for using computers in the first place.
1. People usually regard computers as __________.
A. part of a network B. means of exchanging intelligence
C. personal machines disconnected from outside
D. a small cabin at the end of a street .
2. The writer mentions “ a thief ”in the second paragraph most probably to .
A. show that a hacker is more dangerous than a thief
B. tell people that thieves like to steal computers nowadays
C. demand that a computer network should be set up against thieves
D. look into the case where hackers and thieves are the same people
3. According to the passage , a hacker may do all the damages below EXCEPT .
A. attacking people’s e-mails . B. destroying computer systems .
C. creating many electronic-age terms .
D. entering into computer systems without being discovered
4. By saying “ Now exists the possibility of terrorism by computer ”(the underlined ) the writer means that _______.
A. some employees may erase information from some files
B. students who send out a “ virus ”may do disastrous damages to thousands of computers
C. some people may spread fear in public by destroying computer systems
D. some terrorists are trying to contact each other using electronic mails
Section One
The city is an accumulation of human civilization. Just as the American social philosopher (哲学家) Lewis Mumford put it, it is a special system which, fine and compact, has been designed to preserve the fruits of human civilization. Many Western languages have developed their versions of the term “civilization” from the same Latin (拉丁语的) word “civitas”(meaning “city” ), and it is by no means a coincidence. The city has played a significant role in the perfection of order in human society.
Section Two
The emblem, showing the image of three people ― you, me, him/her holding hands together, symbolizes the big family of mankind. Inspired by the shape of the Chinese character “世” (meaning the world), the design conveys the organizers' wish to host an Expo which is of global scale and which showcases the various urban cultures of the world.
Section Three
Created from the inspiration of Chinese character “人”, the design roots deeply in Chinese culture. It tells the world the eternal core (永恒的核心) and theme of Shanghai World Expo will be always human. The mascot “Haibao” will become the messenger for the theme of World Expo 2010 Shanghai China “Better City, Better Life”.
The basic structure of the Chinese character “人” in which each stroke supports each other also shows the concept that the beautiful life should depends on mutual-help. If the human are willing to support one another, the harmony among human, nature, and society will be available. Such an urban life will be nice.
Haibao’s confident smile is expressing his sincere greeting from China ― “World Expo 2010 Shanghai China welcomes you!”
