It is present in the body in a very small amount, but it makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work. Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force, noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate(硫酸鋅) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate. The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein(蛋白質(zhì)) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters. 1One of the functions of zinc is that it can _.Amake people's bones strongerBhelp people recover fasterCbe good for people's memoryDchange people's sleep for the better2How can the amount of zinc in the body found?Aby examining blood and hair.Bby checking tears and sweat.Cby taking people's temperatures.Dby testing people's blood pressure.3To get enough zinc, people should eat foods that contain _.Aa lot of fibre   Bhigh fatCmuch protein  Dmany vitamins4Which of the following statements is true?APeople need a large amount of zinc to be healthy.BZinc must be used in the course of medical operation.CZinc allows important chemical actions to take place in cells.DScientists added only zinc to the foods that the laboratory animals ate.參考答案1B 2A 3 C 4CPassage 2（2019中考教育類選練）Here is a story: A man sees a butterfly(蝴蝶). The butterfly tries to get out of its chrysalis(蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesnt struggle(掙扎；奮斗) to leave the chrysalis, it cant fly! The struggle develops the energy in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.       When people are young, meeting and overcoming challenges will make them strong and ready to face life. When we look at successful people, we see that the most successful of them are people who have had to struggle. One famous businessman, who now owns many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His fathers death forced him to mature fast. He had to bring up a family of nine people. He took up the challenges and overcame them. Today his brothers and sisters are leading successful lives.       Sometimes challenges do not appear to us because we keep away from them. So some parents and teachers actively encourage young people to face challenges. They might organize some activities for young people which provide them with challenges, like rock-climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of tomorrow. For countries to continue to become successful, it is important that the young people learn to meet challenges and overcome them.1.

Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a clay. Scientists say that none of the differences is really important. It doesnt matter whether foods are eaten raw or cooked. It doesnt matter if a person eats dinner at 4 oclock in the afternoon or at eleven oclock at night. The important thing is what you eat every day.      Paragraph 3：There are two problems，then，in feeding the large number of people in the earth.

But about 97%of that is sea water or salt water. Man can only drink and use the other 3%of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.    Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.    How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain（酸雨）, is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough dean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water i used only once and then sere out into a sewer system（下水道）. From there it returns to the sea or goes underground.    But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.1. The world is thirsty for water because_. Awe don't have enough fresh water Ba lot of water goes into sewer systems Conly 70% of the earth's surface is water Dsea water is widely used rather than fresh water2. The underlined word "face" means"_". Aturn the face down                      Bturn the face up Cturn the face to                            Dturn the face back3. From this passage, we know acid rain_. Ais only bad for living things Bis not bad for buildings and factories Ccan be produced in factories Dis bad for people, animals, plants and buildings4. One difficult way we can solve the problem is to _. Ause the water with salt in it                           Bremove the salt from sea water Cget water from underground                         Dreuse the water in cities5. What is the best title for this passage?AFresh water and sea water                           BA thirsty countryCThe importance of water                            DThe world's water problem參考答案ACDBDPassage 5（2019中考選練）What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage. Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts. From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving by windows with the least chance of serious injury. The second floor window is usually not very high from the ground. An average(平均高度的) person, hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked(滲) into the room.On a second or third floor, the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement(水泥) might end in injury. Bushes and grass can help to break a fall. (    )1. It is important to _.
