Climate change, pollution, overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze, India’s Ganges and African’s Nile, WWF said on Tuesday. At the global launch of its report “World’s Top 10 Rivers at Risk”, the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic life.
“If these rivers die, millions will lose their livelihoods, biodiversity will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security,” said Rayi Singh, secretarygeneral of WWF-India. The report launched ahead of “World Water Day” today, also cited the Rio Grande in the United States, the Mekong and Indus in Asia, Europe’s Danube, La Plata in South America and Australia’s Murray-Darling as in need of greater protection.
Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up. Dams have destroyed habitats and cut rivers off from their flood plains while climate change could affect the seasonal water flows that feed them, the report said. Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found… The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes of sediment from land conversion.
Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa’s arid Nile basin. Tributaries flowing into the Ganges are drying up because of irrigation, WWF said.

There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serous problems. Even though we have good intentions, we may be producing too much, too fast.
Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world’s population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. They believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.

A. our natural surroundings are in danger of being destroyed by industry
B. the fixed supply of natural resources marks a point beyond which economic growth cannot continue
C. the world population is ever increasing
D. more efforts should be made to improve the quality of our material life
61. Those who want more economic growth believe that continued economic growth ________.
A. is essential to the well-being of society as a whole
B. can provide the solution to many of our social problems today

There’s a box of chocolates in the fridge. It’s been there for more than a week since I was given it as a present. I do love chocolates, but they make me fat if I eat too many! Can I control myself? If I eat one, will I have to eat all of them?
My son Harry is obsessed with playing Wii(/wi:/, 任天堂的一款游戏机) games. Sometimes, it’s difficult to get him to concentrate on his homework because he wants to play some more.
Last week I had to wake up a student in my class. I asked him why he was so tried and he said he had stayed up late to play his favourite Internet game, Farmville. He said he just couldn’t stop playing it! Now his academic work is suffering because he can’t control his urge to play games.
What my son, my student, and I myself need is simply self-control.
In the late 1960’s, American psychologist Walter Mischel launched an experiment about self-control. He left a group of four-year-olds in a room and told them that if they could wait 20 minutes, they could have two marshmallows, a kind of sweet. If they couldn’t wait, he would only give them one.
In videos of the experiment, you can see children squirming, kicking, hiding their eyes—desperately trying to control themselves. Some did wait patiently, while others couldn’t wait a single minute.
Years later, the self-controlled children turned out to get higher SAT scores and got into better colleges. The children who couldn’t wait were more likely to become bullies.
So, the chocolates are still in the fridge. My son Harry is doing his homework with a promise that he can play on the Wii later, and my student says he will try harder to control himself. We all have our own temptations. But if we can control them, we will achieve more.

A. all the children got two marshmallows
B. all the children waited patiently
C. self-control can help children succeed later
D. the children who lack self-control get higher SAT scores
58. Which of the following statement is true?
A. The writer is addicted to Wii.
B. The writer’s son is addicted to Farmville.
C. The writer’s student is addicted to chocolates.
D. The writer’s student is addicted to Farmville.

It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don’t understand them. They often think that their parents are out of touch with modern ways, that they are too serious and too strict with their children, and they seldom give their children a free hand.
It is true that parents often find it difficult to win their children’s trust and they tend to forget how they themselves felt when young. For example, young people like to act on the spot without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Older people worry more easily. Most of them plan things ahead, at least in the back of their minds, and do not like their plans to be upset by something unexpected. When you want your parents to let you do something, you will have better success if you ask before you really start doing it.
Young people often make their parents angry with their choice in clothes, in entertainment and in music．But they do not mean to cause any trouble: it is just that they feel cut off from the older people’s world, into which they have not yet been accepted．That’s why young people want to make a new culture of their own, and if their parents do not like their music or entertainment or clothes or their way of speech, this will make the young people extremely happy.
Sometimes you are so proud of yourself that you do not want your parents to say, “ Yes” to what you do. All you want is to be felt alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents’ control. If you plan to control your life, you’d better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility, they will certainly give you the right to do what you want to do.

The United Nations says forty million people or so around the world went hungry in 2008, mainly because of higher food prices. Early estimates from the UN Food and Agriculture Organization (FAO) show that 963 million people did not get enough to eat.
World food prices have dropped since early 2008. Prices of major crops have decreased by more than half from their height earlier last year. But they remain high compared to earlier years.
But FAO official Hafez Ghanem says lower prices have failed to end the food crisis (危机) in many poor countries. “For millions in developing countries,” he says, “getting enough food every day to live an active and healthy life is a distant dream.”
The FAO says food shortage is a threat to people's health. Today, two-thirds of the world's undernourished people live in just a few countries. These are India, the Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan, Ethiopia and so on.
A report on food insecurity warns that the current economic crisis could send even more people into hunger and poverty.
In sub-Saharan Africa, the percentage of the people who continually go hungry fell from 34% in 1997 to 30% in 2008. But the FAO says Ghana is the only country that has reached two sets of hunger reduction targets. These were set by the 1996 World Food Summit and the Millennium Development Goals. The main reason is the growth in agricultural production in Ghana.
The FAO says some countries in Southeast Asia like Thailand and Vietnam have made progress in hunger reduction goals. But South Asia and Central Asia haven't, and North Korea is still in hot water.
68. What FAO official Hafez Ghanem says implies（暗示）__________
A. it's easy but takes long to provide people with enough food
B. enough food can make people more active and healthier

69. Ghana has reached the targets of hunger reduction mainly because of ________.
A. the still high food prices
B. the donation of developed countries
C. the two targets of hunger reduction
D. the growth in agricultural production
70. The underlined word "undernourished" in Para. 4 probably means ________.
A. hungry and unhappy B. unhealthy for lack of food
C. not fat because of povertyD. undeveloped and poor
71. What is the best title of this passage?
