Much less than one percent of the earth's water can be used by humans. Areas that need a lot of water often have to bring it in from far away. For example, southern and central California get most of their water from northern California. The Middle East and Mexico are among the places where large areas are short of water. Much of the shortage (短缺) in such places is caused by poor use of water, such as pollution and waste.

    Most places have enough water for drinking, farming and industries. However, as cities grow larger and industries expand, more and more water is needed. This may mean that more sources (来源) of water need to be found. But by saving water, existing (现有的) water can be used longer. This allows towns, cities and industries to grow without the need to find more water sources.

    What are some ways that ordinary people can save water?

A survey shows that washing clothes, taking showers and using toilets make up about 80 percent of a family's water usage. So using showerheads, toilets, and taps that use less water can help save a lot of water in the home. 

(    ) 53. One of the possible reasons why Middle East and Mexico are short of water is               that ________.

          A. many industries in these places use a lot of water

          B. they pollute and waste existing water

          D. they don’t have enough money to buy water

(    ) 54. What's the meaning of the underlined word "expand"?

(    ) 55. According to the survey, which probably use the least water in families?

         A. Taking showers.             B. Using toilets.

         C. Washing dishes.             D. Washing clothes.

(    ) 56. Which of the following can we learn from the passage?

Tourism(旅游业)wasn’t as important as it is today. In the past, only people with a good deal of money could travel on holidays to other countries. More people travel today than in the past because there is a growing middle class in many parts of the world. That is to say, people now have more money for travelling. Special airplane fares for tourists make travel less expensive and more attractive(吸引人的)than ever before.
Different people have different reasons for travelling. But most people enjoy seeing countries that are different from their own. They also like to meet new people and enjoy new food.
Tourism has many changes in a country and in people’s lives. People build new hotels and restaurants and train local men and women as guides to show visitors interesting places.
【小题1】What makes travel more attractive than before?

Michelle, a famous lady, has found that more than 25% students are too fat in her country. It is a very serious prom. So she starts a health program to deal with it. The health program is to reduce(减少) the amount （数量）of fat students today and in the future.

The program will get families, schools, newspapers, magazines and TVs to join together and deal with the students’ obesity so that students will be at a healthier weight. The program includes: Food stores should sell healthier foods. Schools should serve healthier meals with less fat and should also offer gym classes.

The lady is trying to fight the students’ obesity all over the country because it can cause illnesses and higher health cost. She wants the students to eat right, exercise more and control (控制) their weight. She also wants the students to understand it is important to have less sweet food, and drink water, milk and fresh juices, but not to choose cokes. At the same time she has also set a good example by planting a vegetable garden. She hopes that the garden will encourage more people to plant one too.
