　二、阅读下面文字，完成7?10题。(共16分。每小题4分)

　阅读下面的文字，完成下面试题

　树木都是比较长寿的，自然界中常有许多百年以上的大树，甚至也有上千年的古树。一般比较准确地确定古树的年龄，多用?数年轮?的办法。

　什么是年轮呢?就是木本植物茎干横断面上的同心轮纹，在树木茎干的韧皮部内侧有一圈细胞生长特别活跃，分裂也极快，能够形成新的木材和韧皮组织，被称为形成层。可以说树干的增粗全靠它的力量，这些细胞的生长情况在不同的生长季节中有明显的差异。春天到夏天的天气是最适于树木生长的，因此形成层的细胞分裂较快，生长迅速。所产生的细胞体积大，细胞壁薄，纤维较少，输送水分的导管数目多，称为春材或早材;到了秋天，由于形成层的细胞的活动逐渐减弱，产生的细胞当然也不会很大，而且细胞壁厚，纤维较多，导管数目较少，叫做秋材或晚材;当年的早材与晚材逐渐过渡，组成一轮，而晚材与次年的早材之间，界限分明，出现轮纹，根据树干基部的年轮，可以推测树木的年轮。

　但是也有一些植物，如柑橘，年轮就不符合这种规律，我们叫它?假年轮?，因为它们每一年能够有节奏地生长三次，形成三轮。此外，在热带地区的树木，由于气候季节性的变化不明显，形成层所产生的细胞也就没有什么差异了，年轮往往不明显。

　古树年轮的研究，对近年开展的古气候讨论以及空气污染情况的研究都大有助益，首先树木的生长与气象的关系最为密切，从年轮宽，生长量大，推出那一时期风调雨顺，气温适宜;反之，年轮窄，则雨水稀少或干旱无雨，或气温过高或过低。美国科学工作者通过研究450株?世界爷?的年轮，发现它所记录的近百年气候变化，竞与现有文字记录相吻合;我国兰州大学在祁连山区采集900岁以上的圆柏树，发现其年轮宽窄变化与我国近1000年的气候变化相一致。此外，采用科学手段，可以从年轮里观察出空气污染的程度，美国有人对二氧化碳及氧化物散落较多的军工厂附近的43株美国五针松及50棵鹅掌楸进行年轮分析，发现这些树木的历年生长量与该厂排放的污染物质的多少有密切关系，污染物多，树木生长量就少。

　第7题单选 下列对树木年轮的解释，最准确的一项是(　　)

　A.树木年轮就是木本植物茎干横断面上的同心轮纹。

　B.树木年轮是木本植物的主干由于季节变化生长快慢不同，在木质部的断面显出的环形纹理。

　C.在树木茎干的韧皮部内侧有一圈细胞生长特别活跃，分裂也极快，能够形成新的木材和韧皮组织，它们就是树木年轮。

　D.当年的早材与晚材逐渐过渡，组成一轮，而晚材与次年的早材之间，界限分明，出现轮纹。

　参考答案：B

　第8题单选 下列对?根据树干基部的年轮，可以推测树木的年轮?这句话的理解错误的一项是(　　)

　A.树木都是比较长寿的，自然界中常有许多百年以上甚至上千年的古树。

　B.树木茎干的韧皮部内侧的细胞在不同的季节生长情况有明显的差异。

　C.当年的早材与晚材逐渐过渡，组成一轮，而晚材与次年的早材之间，界限分明，出现轮纹。

　D.除个别植物外，大多数植物符合这种一年增长一轮的规律。

　参考答案：A

　第9题单选 下列对古树年轮研究的益处，表述不正确的是(　　)

　A.树木的生长与气象的关系最为密切，研究古树年轮可以帮助我们了解古时的气候变化。

　B.树木的生长与它附近污染物质的多少有密切关系，研究古树年轮可以帮助我们了解古时的污染程度。

　C.研究古树年轮可以帮助今人印证对过去气候变化的记录。

　D.研究古树年轮可以帮助我们预测将来的气候变化和污染情况。

　参考答案：D

　第10题单选 根据原文提供的信息，以下推断正确的一项是(　　)

　A.要想准确计算古树的年龄，一定要用?数年轮?的办法。

　B.有些植物中的?假年轮?现象，会对准确判断树木的年龄产生一些干扰。

　C.美国的?世界爷?和我国的圆柏树，它们的年轮足以证明古气候变化和空气污染 情况。

　D.从对古树年轮的研究中，可以推出美国过去有许多军工厂。

　参考答案：B

　In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The ―spider story‖ is often told. Robert Bruce, leader of the Scots in the 13th century, was hiding in a cave from the English. He watched a spider spinning a web(蜘蛛织网). The spider tried to reach across a rough place in the rock. He tried six times without success. On the seventh time he made it and went on to spin his web. Bruce is said to have taken heart and to have gone on to defeat the English? Edison, the inventor of the light bulb, made hundreds of models that failed before he found the right way to make one.

　So what? First, always think about your failure. What caused it? Were conditions right? Were you in top from yourself? What can you change so things will go right next time?

　Second, is the goal(目标)you're trying to reach the right one? Try to do some thinking about what your real goals may be. Think about his question, ?If I do succeed in this, where will it get me?This may help you prevent failure in things you shouldn't be doing anyway.

　The third thing to bear in mind about failure is that it's a part of life. Learn to ―live with yourself‖ even though you may have failed. Remember, ―You can't win them all.‖

　A.succeeded B.failed C.gave D.got

　3.The lesson the spider taught Robert Bruce seems ______ .

　A.productive　B.straight forward C.sorrowful D.deep

　4.The author tells you to do all things except ______ .

　A.The think about the cause of your failure

　B.to check out whether your goals are right for you

　C.to consider failure as a part or life

　D.to bear in mind that you will never fail in your life

　5.Which of the following is NOT true?

　A.Bruce and Edison were successful examples. B.Failure may be regarded as a way toward success.

　C.Edison learned a lot from the lesson the spider taught Robert Bruce.

　In sport the sexes(性别)are separate. Women and men do not run or swim in the same races. Women are less strong than men. That at least is what people say. Women are called the weaker sex, or, if men want to please them, the fair sex. But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men .

Conditions are very different now and sport is much more serious. It is so serious that some women athletes are given hormone (荷尔蒙)injections(注射). At the Olympics a doctor has to check whether the women athletes are really women or not. It seems sad that sport has such problems.

　People bury treasure to stop other people from taking it. They choose a quiet place, dig a deep hole and bury the treasure in it. Then they make a map of where the treasure is or write down other clues(线索)that will help them or someone else to find it again.

　In Britain a few years ago; a writer wrote about some treasure that he had buried. He put clues in the story to help readers find it. Thousands of people hunted for the treasure. They dug holes all over Britain, hoping to find it.

　One of the most popular adventure stories ever written is Robert Louis Stephenson's ?Treasured Island?, an exciting story about a young boy, Jim Hawkins, who is captured by pirates and later finds some buried treasure.

　Then there is the true story about a man who had to travel overseas for a year. He did not trust banks, so he buried his life savings in a park. Then he went away. On his return, he went straight to the park. But the park was no longer there. In its place there was a huge building.

　And then there was the man who buried his savings, all in bank notes, in a waterproof(防水的) bag. When he dug it up years later, there was nothing left. Worms and insects had eaten the bag and everything in it.

　And of course, these are stories about people who bury things and either forget where they have buried them or lose the map.

　Although it is true that people sometimes lose their money because a bank fails, banks are still the safest place to keep our savings and treasures.

　1.People who bury treasure usually

　A.do not trust banks

　B.have a little money .

　C.want to live in a quiet place.

　history

　If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember But if we had kept a book and had written in it an account of what we did each day，we should be able to give an answer to the question.

　It is the same in history Many things have been forgotten because we do not have any written account of them Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war.Sometimes there was never any written record at all because the people of that time and place did not know how to Write.For example，we know a good deal about the people who lived in China 4，000 years ago, because they could write and leave written records for those who lived after them.But we know almost nothing about the people who lived even 200 years ago in central Africa. because they had not learned to write. Sometimes.of course，even if the people cannot write，they may know something of the past.They have heard about it from older people，and often songs and dances and stories have been made about the most important happenings，and these have been sung and acted and told for many generations For most people are proud to tell what their fathers did in the past.This we may call ?remembered history?.Some of it has now been written down. It is not so exact or so valuable to us as written history is，because words are much more easily changed when used again and again in speech than when copied in writing.But where there are no written records，such spoken stories are often very helpful.

　41. Which of the following ideas is not suggested in the passage?

　A.?Remembered history?，compared with written history，is less reliable

　B.Written records of the past play the most important role in our learning of the human history.

　C.A written account of our daily activities helps US to be able to answer many questions.

　D.Where there are no written records.there is no history.

　42.We know very little about the central Africa 200 years ago because

　A.there was nothing worth being written down at that time

　B .the people there ignored the importance of keeping a record

　C.the written records were perhaps destroyed by a fire

　D.the people there did not know how to write

　43.?Remembered history?refers to

　A.history based on a person?s imagination

　B .stories of important happenings passed down from mouth to mouth

　C .songs and dances about the most important events

　D .both B and C

　44.?Remembered history?is regarded as valuable only when

　A. it is written down

　B .no written account is available

　C.it proves to be time

　D.people are interested in it

　45 .The passage suggests that we could have learned much more about our past than we do now if the ancient people had

　A.kept a written record of every past event

　B. not burnt their written records in wars

　C.told exact stories of the most important happenings

　D.made more songs and dances

　答案：DDDBA

　land produces

　Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society Less than a tenth of the people are engaged in agriculture and forestry(林业)，and most of the rest live in or around towns，small and large.Here the traditional picture is changing：every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more.Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs、of more than a million people each?a larger proportion than in Germany or England，let alone France.The statistics(统计)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day.As the rush to live out of town continues.rural areas within reach of towns are gradually filled with houses，so that it is hard to say at what moment a piece of country becomes a suburb But more and more the typical American lives in a metropolitan rather than a small town environment.

　A.About 25 million.

　C.Of urban areas.

　D.Of rural areas.

　39.According to the passage，what can we learn about small towns in the United States?

　A Most small towns become gradually crowded

　B.Small towns are still similar to each other.

　C.As the traditional picture is changing，towns are different.

　D .Small towns are turning into large cities

　40.Why is it hard to say when a piece of country becomes a suburb?

　B.Because the rush takes place too quickly

　C.Because the process is gradual.

　D.Because more and more Americans live in metropolitan

　答案：CCABC

　president
