二、阅读理解qb3★济宁成人高考报名0537-2229526

Passage 1qb3★济宁成人高考报名0537-2229526

I don't think there is anything wrong with your blood. The key to your problem is that long nap(打盹,小睡)after dinner.If you didn't sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn't nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day. You should get out of the habit of sleeping during the evening. Right after your evening meal, engage in some sort of physical activity - a sport such as bowling, perhaps. Or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good nights rest without taking a pill. If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up and watch television or do some jobs around your house until you feel sleepy. If you fall asleep and then wake up a few hours later, get up but do not take a sleeping pill. Read a while or listen to the radio, and make yourself a few hours' sleep that night, you will feel better in the morning than you usually feel after taking a pill. The next night you will be ready to sleep at an earlier hour. The most important thing is to avoid taking that nap right after dinner and avoid taking pills.qb3★济宁成人高考报名0537-2229526

Passage 2qb3★济宁成人高考报名0537-2229526

Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date? Many people are afraid to assert(表现)themselves. Dr.Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it's because their self-respect is low. Our whole set up(体制)is designed to make people distrust themselves, says Alberti. There's always' superior' around–a parent, a teacher, a boss-who' knows better'. There superiors often gain when they chip(削弱)away at your self-image. But Alberti and other scientists are doing something to help people assert themselves. They offer assertiveness training courses–AT for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more active without hurting other people. In one way, learning to speak out is to overcome fear. A group taking an At course will help the timid person to lose his fear. But At uses an even stronger motive-the need to share. The timid person speaks out in the group because he wants to tell how the feels.  Whether or not you speak up for yourself depends on your self-image. If someone you face is more important than you, you may feel less of a person. You start to doubt your own good sense. You go by the other person's demand. But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.qb3★济宁成人高考报名0537-2229526

Apositive  Bnegative  Chostile  Dappreciativeqb3★济宁成人高考报名0537-2229526

三、句子翻译qb3★济宁成人高考报名0537-2229526

1. Evaporation of the solution after electrolysis yields crystal of sodium hydroxide. Chlorine is prepared commercially in the same process.qb3★济宁成人高考报名0537-2229526

2. Major uses of sodium hydroxide include the preparation of soaps and other detergents, paper making, purification of aluminum ore, and petroleum refining.qb3★济宁成人高考报名0537-2229526

3. This lime-soda process, however, is no longer competitive with the electrolytic method. In the electrolytic method, a direct current is passed through an aqueous solution of sodium chloride.qb3★济宁成人高考报名0537-2229526

4. Sodium hydroxide is available as white crystals or as pellets. It must be stored in tightly stoppered containers; otherwise, the solid becomes wet with moisture absorbed from the atmosphere. qb3★济宁成人高考报名0537-2229526

5. The unreactivity of nitrogen seemed an insurmountable obstacle. But, in 1909, Fritz Haber (1863-1934) discovered that with the right combination of catalyst, temperature, and pressure, he could convert nitrogen with hydrogen to ammonia in good yields.qb3★济宁成人高考报名0537-2229526

6. Sulfuric acid has many uses, most involve its acid properties. The fertilizer industry uses enormous quantities of sulfuric acid to produce a soluble calcium dihydrogen phosphate, Ca(H2PO4)2, from insoluble phosphate rock, which is essentially Ca3(PO4)2.qb3★济宁成人高考报名0537-2229526

7. They found that an electrical discharge, or arc, made with graphite electrodes in helium atmosphere generated carbon soot with unusual properties. Part of that soot dissolved in ordinary organic solvents such as benzene and toluene; normal soot does not dissolve in these solvents.qb3★济宁成人高考报名0537-2229526

8. A compound is a pure substance that contains more than one element. Water is a compound of hydrogen and oxygen. The compounds methane, acetylene, and naphthalene all contain the elements carbon and hydrogen, in different proportions.qb3★济宁成人高考报名0537-2229526

9. Nitric acid, HNO3, was known to early chemists as aquafortis, which is Latin for “strong water”.  The name presumably comes from the fact that nitric acid reacts with most metals, including copper and silver which are not attacked by other acids.qb3★济宁成人高考报名0537-2229526

10. The present industrial method of preparing nitric acid was discovered in 1902 by German chemist Wilhelm Ostwald, who received the Nobel Prize in chemistry in 1909 for his work in catalysis.qb3★济宁成人高考报名0537-2229526

11. Ammonium nitrate is used as a nitrogen fertilizer and in the manufacture of explosive mixtures. (For example, a fuel oil-ammonium nitrate mixture is used as a mining explosive.)qb3★济宁成人高考报名0537-2229526

12. The food industry uses hydrochloric acid to make corn syrup from cornstarch and to make gelatin from bones.   These reactions involve the breaking down of large molecules to smaller ones by the action of the acid.qb3★济宁成人高考报名0537-2229526

13. Iron metal also reacts with hydrochloric acid but more slowly, so that the rust can be removed from steel without significant loss of iron. Iron, like most metals, reacts with hydrochloric acid in a displacement reaction.qb3★济宁成人高考报名0537-2229526

14. Sulfuric acid has many uses, most involve its acid properties. The fertilizer industry uses enormous quantities of sulfuric acid to produce a soluble calcium dihydrogen phosphate, Ca(H2PO4)2, from insoluble phosphate rock, which is essentially Ca3(PO4)2.qb3★济宁成人高考报名0537-2229526

15. They found that an electrical discharge, or arc, made with graphite electrodes in helium atmosphere generated carbon soot with unusual properties. Part of that soot dissolved in ordinary organic solvents such as benzene and toluene; normal soot does not dissolve in these solvents.qb3★济宁成人高考报名0537-2229526

16. A compound is a pure substance that contains more than one element. Water is a compound of hydrogen and oxygen. The compounds methane, acetylene, and naphthalene all contain the elements carbon and hydrogen, in different proportions.qb3★济宁成人高考报名0537-2229526

17. They could be familiar plastics like polyethylene or the more esoteric plastics used in unbreakable windows and nonflammable clothing. Other materials, including metal alloys, semiconductors, and superconductors, are inorganic in nature.qb3★济宁成人高考报名0537-2229526

18. Today, ultrapure silicon has become the basis for the multibillion-dollar semiconductor industry. Lead, on the other hand, is an element moving in the other direction.qb3★济宁成人高考报名0537-2229526

19. When you shake iron filings with powdered sulfur, a mixture is formed; the two elements are chemically unchanged.qb3★济宁成人高考报名0537-2229526

20. Sulfuric acid has many uses, most involve its acid properties. The fertilizer industry uses enormous quantities of sulfuric acid to produce a soluble calcium dihydrogen phosphate, Ca(H2PO4)2, from insoluble phosphate rock, which is essentially Ca3(PO4)2.qb3★济宁成人高考报名0537-2229526
