Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger ,but we also affect our water supply in less obvious ways .
You may wonder how paving(铺砌) a road can lead to less useable fresh water . A major part of the water we use every day is groundwater . Groundwater does not come from lakes or rivers .It came from underground . The more roads and parking lots we pave ,the less water can flow into the ground to become groundwater .
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall ,but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference ,too. In the United States ,a family of four can use 1.5tons of water a day ! This shows how much we depend on water to live ,but there’s a lot we can do to lower the number .
You can take steps to save water in your home .To start with ,use the same glass for your drinking water all day .Wash it only once a day .Run your dishwasher (洗碗机)only when it is full 。Help your parents fix any leaks in your home . You can even help to keep our water supply clean by recycling batteries instead of throwing them away ..Which of the following is most likely to lead to less groundwater ?
| A．paving parking lots . | B．Throwing batteries away . |
| C．Using river water | D．Throwing rubbish into lakes . |
What can be inferred from the text ?
| A．All water shortages are due to human behavior . |
| B．There is much we can do to reduce family size . |
| C．It takes a lot of effort to meet our water needs . |

The last paragraph is intended to .
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
The text is mainly about .

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 wi
th 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 ma
y not be rational which you may regret later. To minimize (使减到最小) the negative influence, change the safe
ty 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.

He was 1
1 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 nigh
t 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.

Bamboo (竹子) is one of nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 meters in 
24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo.
