　　Saving the Earth Passage 1

　　阅读理解一

　　Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA)obviously proves the theory that the burning 900degree Fahrenheit surface temperature of Venus is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet's atmosphere, warms is surface, and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus's atmosphere from top to bottom so that NASA's scientists are able to prove the exact amount of sunlight received at various places in the planet's atmosphere and on its surface. Measurements of atmosphere, temperature, and radiative heating foresee Venus's surface temperature very exactly. The planet is closer to the Sun than it is to the Earth, and it has a thin atmosphere like the Earth's but Venus atmosphere is made up of more than ninety percent carbon dioxide, compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide, Venus's atmosphere receives much more heat radiation than the Earth's does. Thus the Venus studies are believed to be important to the understanding of possible bad effects on Earth's agriculture and sea levels that could result from the longterm use of fuels, which add carbon dioxide to the atmosphere.

　　Passage 2阅读理解二

　　Every animal is a living radiator——heat formed in its cells and given off through its skin.Warmblooded animals keep a normal temperature by continuously replacing lost surface heat;smaller animals,which have more skin for every ounce of body weight,must produce heat faster than bigger ones.Because smaller animals burn fuels faster,scientists say they live faster.

　　The speed at which an animal lives is determined by measuring the rate at which it uses oxygen.A chicken,for example,uses onehalf cubic centimeters of oxygen every hour for each gram it weighs.The tiny shrewmouse uses four cubic centimeters of oxygen every hour for each gram it weighs.Because it uses oxygen eight times as fast,it is said that the shrewmouse is living eight times as fast as the chicken.The smallest of the warmblooded animals,the humming bird,lives a hundred times as fast as an elephant.

　　There is a limit to how small a warmblooded animal can be.A mammal or bird that weigh only two and half grams would starve to death.It would burn up its food too rapidly and would not be able to eat fast enough to supply more fuel.

　　()3The amount of oxygen an animal uses depends on .

　　A、the heat the body produces

　　B、the food it eats

　　C、its size and shape

　　D、the length of time it lives

　　()4According to the passage,which of the following is possibly right?

　　A、There is no limit as to how large a warmblooded animal can be.

　　My husband hasn't stopped laughing about a funny thing that happened to me.It's funny now but it wasn't at the time.

　　Last Friday,after doing all the family shopping in town,I wanted a rest before catching the train, so I bought newspaper and some chocolate and wentsintosthe station coffeeshop, the cheap selfservice place with long tables to sit at.I put my heavy bag down on the floor,put the newspaper and chocolate on the table to keep a place,and went to get a cup of coffee.

　　When I came back with the coffee,there was someone in the next seat.It was one of those wildlooking youngsters,with dark glasses and worn clothes,and hair coloured bright red at the front.Not so unusual these days.What did surprise me was that he'd started to eat my chocolate!

　　Naturally,I was annoyed.However,to avoid troubleand really I was rather uneasy about him. I just looked down at the front page of the newspaper,tasted my coffee and took a bit of chocolate.The boy looked at me closely.Then he took a second piece of my chocolate.I could hardly believe it.Still I didn't start an argument.When he took a third piece,I felt more angry than uneasy.I thought,“Well,I shall have the last piece.”and I got it.

　　The boy gave me a strange look,then stood up.As he left he shouted out,“This woman's crazy!”Everybody stared.That was embarrassing enough,but it was worse when I finished my coffee and got ready to leave.My face turned red——as red as his hair——when I realized I'd made a mistake.It wasn't my chocolate that I'd been taking.There was mine,unopened,just under my newspaper.

　　参考答案

　　Passage 1

　　1、D本文谈到了宇宙探测器对金星探测的一些情况，从而了解到金星也存在着温室效应，故选D。

　　2、B文章第二句已说明金星大气层吸收了热辐射。

　　3、A从“The planet is claser... but venus atmasphere is made up of more than..., Compare to... of the Earth”可以看出，金星大气层中二氧化碳的含量要比地球大气层中的二氧化碳含量高许多。

　　4、D温室效应的后果是地球的气温发生变化。

　　5、B通过对金星的确定，人们可以从中获得一些有用的信息来预报地球上农业生产可能会出现的问题。

　　Passage 2

　　1、C从文章第一段第一句可以找出答案。

　　2、C文章第一段后两句话告诉我们，越是小动物释放热量越快。上文已说明动物是通过皮肤排放热量的。

　　3、A阅读文章第二自然段，可确定正确答案为A。

　　4、B根据文章意思来判断B项正确。因为我们都知道：“蜂鸟是飞禽界的直升飞机。”

　　Passage 3

　　1、Dgo abroad意为“出国”，而be abroad是“在国外”的意思。本句是一个常用句型。

　　2、Bat school意为“在学校上学”；in a factory意为“在工厂”；in the countryside意为“在农村”。平时应注意介词的习惯用法。

　　3、Cbe(get)used to doing sth.意为“习惯做某事”。

　　4、C前面提到了作者16岁时到美国去观光，在学校上学时曾学过法语，因此，在美国他习惯讲法语，然而美国人又不懂法语。

　　5、Clook forward to doing sth.是固定短语，意为“盼望做某事，渴望做某事”。have a holiday是固定搭配，意为“度假”。

　　6、A本文作者到美国后，他发现在学校学过的法语在与美国朋友交流时有困难，因此，他渴望渡过一个没有产生语言交流麻烦的假期。

　　7、AHow wrong...是感叹句。感叹部分是形容词，副词、动词时，感叹词用how,如感叹部分是名词时，感叹部分用What。

　　感叹句型：What

　　How+感叹部分名词

　　副词/形容词+主语+谓语!

　　8、Apublic telephone意为“公用电话”；the public debt意为“国债”；a public school意为“公立学校”。

　　9、Dgive sb、a rihg/call; telephone/phone/call sb、意为“给某人打电话”。

　　10、C一个友好的老人看到我有点迷茫，就问我是否需要帮助。

　　11、DThat's nice.这句话表示他愿意提供帮助，其他不合题意。

　　12、Aget (be)married to sb.意为“与某人结婚”。由于ring是多义词，所以老人产生了误解。作者想找公用电话给女朋友打电话，而那位老人误认为他要送给女朋友戒指准备结婚。此句用进行时表示将来的动作。

　　13、A英语指人年龄大小用old或young,根据上下文来看作者显然很年青，故选young。

　　14、Bjust这里相当于only,意为“仅仅，只是”，起到加强语气的作用。

　　15、BWhere引导宾语从句。

　　16、D助动词do (does，did)+动词原形，在句子中用来加重语气。例：Do come tomorrow!明天一定来!

　　17、Ddifficulies在这里是可数名词，作“困难的事情”。此句表示Danny刚开始遇到了很多困难。

　　18、C此空需要及物动词，故排除speak,而write和read不符合题意。

　　19、B你不久就会习惯于美国人说的所有有趣的话。

　　20、Almost of the time是固定补语意为“大多数时候”。Passage 4

　　1、T阅读文章第二段后可知：本文作者上星期五进城去购物，她一定忙碌了一天。
