    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.

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

          B. they pollute and waste existing water

          C. they have few lakes and rivers

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

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

          A. 发展       B. 使用       C. 浪费       D. 匮乏

(    ) 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?

         A. By saving water, we may not need to find more water sources.

         B. People in southern and central California are rich.

         C. Northern California will not have enough water in the future.

         D. Washing clothes and washing dishes make up 40 % of a family's water usage.

Good beginner tarantulas include the ‘Pink Zebra Beauty’ and the ‘Brazilian Black and White’ because they are not as dangerous as some of the other ones.

How do I look after a tarantula? You can keep tarantulas in 10 gallon, glass boxes. They need a water bowl in the box and you should feed them once a week.
