               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 (來源) of water need to be found. But by saving water, existing (現(xiàn)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
              
                     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. 發(fā)展        B. 使用       C. 浪費(fèi)       D. 匱乏
              
          (     ) 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.

          During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you're tired. Sleep gives your body a chance to rest.
          But your brain (大腦)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(記憶). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
          You also grow while you sleep. The thing called "human growth hormone (荷爾蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
          Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陳代謝) slows down. You are still using some energy, but much less than when you are awake and active.
          Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body's way of saying, "I need sleep！" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.
          【小題1】What does "human growth hormone" do while people sleep?
          A．It helps people rest well.B．It helps repair the body.
          C．It helps answer problems.D．It helps slow the body down.
          【小題2】According to the passage, which of the following tells you need sleep?
          A．You use up a lot of energy.B．You enjoy daily activities.
          C．Your body temperature falls.D．You don't want to get up.
          【小題3】What does the underlined word "conserve" mean?
          A．provideB．moveC．saveD．spend
          【小題4】What is this passage mainly about?
          A．Sleep is very important.B．The brain needs enough sleep.
          C．Good ways to sleep well.D．People use energy when sleeping

          On April 20th,2013, a big and powerful earthquake attacked Ya’an, Sichuan Province. A great many buildings and houses collapsed, a lot of people were killed and even more people lost their homes in the earthquake .

          It’s a long-awaited day for China. The navy now has
its first aircraft carrier(航空母艦), Liaoning.
          


          It’s a unique experience to get to know the life in
the carrier. The carrier is just like a small city on the sea. It has all the
functions for daily life. There are 4 words to sum up its characters: big,
small, much and high. The carrier Liaoning is such a huge one that the total
length of the whole corridor（過道）could reach over 20
kilometers. But the living space for the sailors（水手）is
quite small. That’s because the carrier is designed for researching purposes,
rather than comfortable living. Over 1,000 sailors, both men and women, are
living onboard. They are arranged among over 3,000 tiny rooms below the deck.
For visitors, it’s so easy to get lost. So the first thing the new sailors have
to learn is their way around. The number of female sailors is much less than
that of the males, taking about 5 percent of the total. But they play a key
role in carrying out some special missions.
          


          Also, you will be surprised by the high level of
education of today’s sailors. The captain said that over 90 percent of the
sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s.
The whole team is young but vigorous（朝氣蓬勃的）. The
complex work on the carrier requires high management abilities for the
commanders onboard(在船上). 
          


          1.Why do we visitors get lost easily inside the
carrier?
          


          A．Because they
don’t have a map.
          


          B．Because the
living space is quite small.
          


          C．Because there
are too many corridors for rooms.
          


          D．Because the
corridor inside the carrier is too long.
          


          2.What does the word “high” in Line 6 refer to（指代）？
          


          A．The aircraft
carrier is high since it is just like a small city.
          


          B．Most of the
soldiers received good education.
          


          C．The expense（花費(fèi)）to run a carrier is high.
          


          D．The
high-level of their training.
          


          3.Which of the following is NOT TRUE according to the
passage?
          


          A．Liaoning is
our country’s first aircraft carrier.
          


          B．Most of the
sailors on the carrier are college graduates.
          


          C．There are far
fewer women sailors than men sailors on the carrier.
          


          D．It is
comfortable for the sailors to live in the carrier.
