生物 第九周周清1
生物第九周周清一、单项选择题：1、相同条件下，小麦植株哪一部位的细胞最难以产生新的基因( A )A．叶肉B．根尖分生区C．茎尖D．花药2、下面是有关果蝇的培养记录，通过本实验说明( D )A.B．果蝇的突变率与培养地点所处的海拔高度有关C．果蝇在25 ℃时突变率最高D．果蝇的突变率与培养温度有关3、某二倍体植物染色体上的基因B2是由其等位基因B1突变而来的，如不考虑染色体变异，下列叙述错误的是A．该突变可能是碱基对替换或碱基对插入造成的B．基因B1和B2编码的蛋白质可以相同，也可以不同C．基因B1和B2指导蛋白质合成时使用同一套遗传密码D．基因B1和B2可同时存在于同一个体细胞中或同一个配子中4、在诱导离体菊花茎段形成幼苗的过程中，下列生命活动不会同时发生的是：A.细胞的增殖与分化B.光能的吸收与转化C.ATP 的合成与分解D.基因的突变与重组5、下列有关生物变异的说法，正确的是( C )A．基因重组可以产生多对等位基因B．发生在生物体内的突变和重组都能遗传给后代C．基因重组所产生的新基因型不一定会表现为新的表现型D．基因重组会改变基因中的遗传信息6、5－溴尿嘧啶(Bu)是胸腺嘧啶(T)的结构类似物。
在含有Bu的培养基中培养大肠杆菌，得到少数突变体大肠杆菌，突变型大肠杆菌中的碱基数目不变，但(A＋T)/(C＋G)的碱基比例略小于原大肠杆菌，这表明Bu诱发突变的机制是( C )A．阻止碱基正常配对B．断裂DNA链中糖与磷酸基C．诱发DNA链发生碱基种类替换D．诱发DNA链发生碱基序列变化解析：5－溴尿嘧啶(Bu)是胸腺嘧啶(T)的结构类似物，DNA复制时，少数Bu代替T作为原料，导致(A＋T)/(C＋G)的碱基比例略小于原大肠杆菌，所以碱基种类发生了替换。
7、在细胞分裂过程中出现了甲、乙两种变异，甲图中英文字母表示染色体片段。
下列有关叙述正确的是( C )①甲图中发生了染色体结构变异，增加了生物变异的多样性②乙图中出现的这种变异属于染色体变异③甲、乙两图中的变化只会出现在有丝分裂过程中④甲、乙两图中的变异类型都可以用显微镜观察检验A．①②③B．②③④C．①②④D．①③④解析：由甲图染色体上的基因排序变化可知，染色体发生了结构变异，该变异既可以发生在减数分裂过程中，也可以发生在有丝分裂过程中。

高一英语周周清训练(1)
高一英语周周清1一、完形填空Unfortunately man has killed wild animals, polluted rivers and cut down forests through the ages. But lately people are beginning to realize that their own lives depend on the way they treat “nature” and all living things in it.Man has 1 ways of showing his love to nature. He says he loves it, although he often 2 its beauty. While walking through the woods, how many times have we picked flowers? Then later, as the 3 wither(枯萎), we throw them away. That’s one of the reasons 4 many kinds of plants and flowers have become rare. Or, have you 5 wondered where all the thousands of New Year trees come from and 6 happens to them, once the 7 are over?Man destroys natu re by polluting the air. That’s probably the greatest danger8 our lives. The smoke from factories and 9 from cars and trucks do not only harm the surrounding vegetation(植被). It 10 our earth, too.Man pollutes rivers, seas and oceans. Just think of the 11 fish that die by thousands because of polluted waters.Biologists have 12 that all kinds of wildlife are 13 in the areas where they live. Even the wolf, which we 14 dangerous and “bad”, plays an important role in nature. Here is an interesting example: There is a large 15 in one of the Great Lake between Canada and the US. Early in this century many wild deer invaded(涌入) the island. Nobody knows how they 16 there.The deer multiplied(繁殖) until there were as many as 4,000 on the island. They destroyed 17 of the vegetation on it. Finally, as they couldn’t find enough 18 , they began to starve and die. Then came the wolf. 19 knows how wolves got to the island, but they 20 . The wolves killed those deer that were easiest to catch—the sick, the weak and the old. So, only the strong and the healthy animals were left. The island became green once again and there was enough food for the deer that were left.1、A、lovely B、strange C、many D、much2、A、harms B、breaks C、injures D、destroys3、A、stems B、branches C、roots D、flowers4、A、what B、how C、why D、when5、A、still B、even C、ever D、quite6、A、which B、that C、what D、how7、A、years B、meetings C、parties D、holidays8、A、to B、of C、about D、for9、A、waters B、smells C、gases D、whistles10、A、affects B、efforts C、effects D、causes11、A、poor B、weak C、strong D、ill12、A、studied B、developed C、invented D、discovered13、A、want B、need C、necessary D、helped14、A、consider B、think it C、regard D、think as15、A、field B、land C、mountain D、island16、A、left B、got C、reached to D、arrived in17、A、a whole B、most C、more D、more much18、A、plants B、rice C、vegetation D、food19、A、Nobody B、Anybody C、Somebody D、Everybody20、A、got B、went C、arrive D、did二．阅读理解：AA man once said how useless it was to put advertisements in the newspaper. “Last week”, he said, “my umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising, but didn’t get it back.”“How did you write your advertisement?” asked one of the listeners, a merchant.“Here it is”, said the man, taking out of his pocket a slip out from a newspaper. The other man took it and read, “Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings on leaving it at No.10 Broad Street.”“Now” said the merchant, “I often advertise, and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again, and if it fails, I will buy you a new one.”The merchant then took a slip of paper out of his pocket and wrote. “ if the man who was seen to take an umbrella from the City Church last Sunday evening doesn’t wish to get into trouble, h e will return the umbrella to No.10 Broad Street. He is well known.”This appeared in the paper, and on the following morning, the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown, and his own was among them. Many of them had notes fastened to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter.21、What is an advertisement?A、A news itemB、A public announcement in the press, on TV, etc.C、One way to voice one’s view.D、Public opinions.22、The man once thought advertising was_________.A、of little useB、of some useC、practicalD、valuable23、Why did the merchant say “I often advertise, and find that it pays me well.”?A、He knew how to advertise.B、He had more money for advertising.C、He found it easy to advertise.D、He had a friend in the newspaper where he advertised.24、Did the merchant know who had taken the umbrella?A、SureB、Not very sureC、Not at allD、probably.25、This is a story about____________.A、a useless advertisementB、how to make an effective advertisementC、how the man lost and found his umbrellaD、what the merchant did for the umbrella owner.BYou are seeing a film in which two men are having a fight. They hit one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead!Of cour se he isn’t really dead. With any luck he isn’t even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars or even catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks.They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall onto hard ground but onto empty cardboard boxes covered with a mattress. Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar!But although their work depends on tricks of this sort, it also requires a high degree of skill and training. Often a stuntman’s s uccess depends on careful timing. For example, when he is “ blown up” in a battle scene, he has to jump out of the way of the explosion just at the right moment.Naturally stuntmen are well paid for their work, but they lead dangerous lives. They sometimes get seriously injured, and even killed. A Norwegian stuntman, for example, skied over the edge of a cliff a thousand feet high. His parachute (降落伞) failed to open and he was killed.In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women to perform some dangerous actions. For nowadays there are stunt girls , too.26. What can be inferred from the author’s example of the Norwegian stuntman?A. Sometimes an accident can happen to a stuntman.B. The percentage of serious accidents is high.C. Parachutes must be of good quality.D. The cliff was too high.27. Stuntmen are those who __________________.A. often dress up as actors.B. like to lead dangerous lives.C. often perform seemingly dangerous actions. D .often fight each other for their lives.28. Stuntmen earn their living by ___________________.A. playing their dirty tricks.B. selling their special skills.C. jumping out of high windows.D. jumping from fast moving trains.29. When a stuntman falls from a high building, _____________________.A. he needs little protection.B. he will be covered with a mattress.C. his life is in danger.D. his safety is generally all right.30. Which of the following is the main factor of a successful performance?A. StrengthB. ExactnessC. SpeedD. CarefulnessCRecently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with ( 处理，对付)these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “ diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风) are examples of such diseases.Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco ( 烟草), probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors ( 祖先). We eat more sugar. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.31. According to the passage, people in industrialized nations would be much healthier if theyate____________________.A. more food than humans living 10,000 years ago did.B. as much food as humans living 10,000 years ago didC. more kinds of food eaten by people living over 10,000 years ago.D. more of the same kind of food eaten by people over 10,000 years ago.32. New kinds of sicknesses have been found because ___________________.A. the human body has changed compared with humans who first appeared on the earth.B. the way we live has changed a little.C. our body can’t deal with the changes in life style.D. the way we live today is proper for the human body.33. What is the main cause that people suffer from a lot of new sicknesses?A. Ancient people did a great deal of physical exercise.B. People today have a lot of alcohol.C. People today have more tobacco.D. Food today is quite different from that of ancient times.34. Which of the following belongs to the dairy products?A. MilkB. CornC. PorkD. Flour35. According to some scientists , Stone-age people were much healthier than people todaybecause they ate a lot of _____________.A. milk and other dairy products.B. wild animals, fresh wild vegetables and fruits.姓名：____________C. salt and sugarD. grain foods三、单词填空：1.
