D
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
PAI researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera (霍乱), which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now import sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning. The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day.

H5N1 avian influenza, commonly known as bird flu (流感), has killed at least 15 people across Asia and was proved in China on January 27. No human cases have been found in the mainland, but 13 of the country’s 31 provinces have reported the disease in poultry.
The Chinese government has taken measures to prevent and control the disease. Poultry within 3 km of infected (受感染的) farms is to be killed and those within 5 km vaccinated (接种疫苗). At the same time, there will be continuous monitoring and daily reports on the disease across the country, and increased production of bird flu vaccines.
Among the 11 Asian countries and regions having bird flu in animals, only Vietnam and Thailand have reported human cases. The people infected were reported to have caught the disease from poultry.
While the World Health Organization ( WHO) says there is “no proof (证据) of human-to-human infection (传染)” of bird flu, the big fear is that the disease could combine with a human flu virus (病毒) to produce a deadly new disease that will kill millions of people across the world. Many Asian farmers live closely with their animals and sell live chickens in the market. This greatly increases the chance of humans being infected with bird flu.
A spokesman of the WHO said that Asian countries having bird flu should introduce a more healthy way of raising and selling chickens. The people there have to completely change their way of life and manners towards animals. Here are some safety measures for people to stay healthy;
* Keep fit through usual exercise;
* Avoid infected poultry and infected people;
* Avoid eating uncooked or under-done poultry and eggs;
* Make sure there is always fresh air in your home;
* Cover your mouth and nose when coughing or sneezing;
* Wash your hands as often as possible.
What does the underlined word “poultry” mean?

A.Wild birds.
B.Wild animals.
C.Home-raised birds.
D.Home-raised animals.

From the passage, we learn that __________.

A.infected poultry within 3 km was killed in China
B.the first bird flu case was proved in China on Jan. 27
C.human infected cases were found in 11 Asian countries
D.over two thirds of China have been affected by the bird flu

What do people fear most?

A.Poultry will infect many people.
B.There will be human-to-human infection.
C.The disease can spread quickly among people.
D.A new disease combining bird flu and a human flu will break out.

Blogs (博客) are the place where young people go to show their hearts, to express their anger, sorrow or disappointment, and even to gossip (说别人的闲话).
Many people enjoy the freedom in blogging. Some, however, find that putting one’s life online can have a price. The blogs of some students in America were stopped by the government for some time because they posted threatening words to their teachers on their blogs.
A recent study finds that nearly a fifth of teens who surf the Internet have their own blogs. And 38 % of teens say they read other people’s blogs. By comparison, about a tenth of adults have their own blogs and a quarter say they read other people’s online magazines.
With the development of the Internet, more and more people will be attracted by blogging.
In another study, 79% of teens agree that people at their age aren’t careful enough when giving out information about themselves online. Besides, careless blogging can also influence blog readers. When you are angry or unhappy, your blog is the first place you turn to. The words you post then may not be rational which you may regret later. To minimize (使减到最小) the negative influence, change the safety setting and make such posts “personal” so that only you can read them.
As long as you are careful with what you post, blogging is a great means of staying in touch with friends and displaying one’s creative works.
Blogs are the place where people __________.

A.go online to have a chat
B.go online to enjoy freedom
C.exchange their views online
D.go online to express themselves freely

The fact that some American students’ blogs were stopped is used to show that __________.

He was 11 years old and often went fishing. On the day before bass (鲈鱼) season opened, he and his father were fishing early in the evening.
When his pole doubled over, he knew something huge was on the other end. His father watched with admiration as the boy skillfully worked the fish. Finally, he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.
Lighting a match, the father looked at his watch. It was 10 pm — two hours before the season opened. He looked at the fish, then at the boy, saying, “You’ll have to put it back, Son.”
Looking around, he saw no other fisherman or boats. Even so, the boy could tell from his father’s voice that the decision couldn’t be changed. He threw the huge bass into the water. The boy thought that he would never again see such a big fish.
That was 34 years ago. Today the boy is a successful architect (建筑师) in New York. He often takes his son to fish at the same place.
And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish… again and again… every time he has an ethical (道德的) decision to make. As his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult.
Seeing the boy skillfully pulling a big fish out of the water, the father felt __________.

A.admiring B.nervous
C.worried D.shocked

On seeing that the big fish was a bass, __________.

A.they discussed how to deal with the fish
B.the boy threw the bass back into the water gladly
C.the father made a decision that the fish must be set free
D.they were worried that other fisherman might know what they had done

From the passage, we can learn that __________.

A.the father was an architect
B.the son never forgets the lesson
C.the father used to catch a big bass
D.the father made his son feel regretful all his life

The passage mainly wants to tell us that __________.

A.an ethical decision is not difficult to make
B.it is hard to tell right from wrong sometimes
C.fishing helps you to make right ethical decisions
D.it’s easier to make an ethical decision than to carry it out
