Passage One

The computer is a useful machine. It is the most important invention in many years. The oldest kind

of computer is the abacus(算盘), used in China centuries ago, but the first large, modern computer was

built in 1946. A computer then could do maths problems quite fast.

Today computers are used in many ways and can do many kinds of work. In a few years the

computer may touch the life of everyone, even people in faraway villages.

In the last few years, there have been great changes in computers. They are getting smaller and

smaller, and computing faster and faster, Many scientists agree that computers can now do many things,

but they cannot do everything. Who knows what the computers of tomorrow will be like? Will

computers bring good things or bad things to people? The scientists of today will have to decide how to

use the computers of tomorrow.

1. The computer is a _______ machine.

A. helpful B. strange C. large D. dangerous

2. The first large, modern computer was built about _______ years ago.

A. a few B. forty C. sixty D. eighty

3. The computers of today are _______ than before.

A. bigger B. fewer C. smaller D. taller

4. Computers can do _______.

A. everything B. anything C. nothing D. lots of things

5. The scientists of today _______ how to use the computers of tomorrow.

A. may decide B. must decide C. can make D. needn’t make

Passage Two

Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred

years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved

the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another

with warm water. He put both in the same low temperature. The warm water froze first. The lack of

covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the

warm water was left to be frozen. And so the warm water froze faster than the cold water even though it

had a greater temperature drop to make.

1. Hundreds of years ago, Sir Francis Bacon found _______.

A. the temperature of warm water drops faster than that of cold water

B. warm water is heavier than cold water

C. warm water has the same temperature as cold water

D. warm water is not as useful as cold water

2. What Sir Francis Bacon said was right, but people didn't believe him until _______.

A. late in the 20th century B. early in the 20th century

C. three years ago D. late in the 19th century

3. Leave a pail with warm water and another pail with cold water in the same low temperature, you’ll

find that _______.

A. cold water freezes first

B. warm water turns into ice before cold water

C. warm water and cold water freeze at the same time

D. much of cold water is changed into air. CCNU JULIE

第2页 共12页 4. Why does warm water freeze first in the same freezing weather?

A. Because some of the warm water turns to vapor, the amount(数量) becomes less than that of

cold water.

B. Because warm water is lighter than cold water.

C. Because the temperature of warm water is lower than that of cold water.

D. Because cold water freezes with more difficulty than warm water.

Passage Three

If you do not use your arm or your legs for some time, they become weak; when you start using

them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to

know that memory works in the same way. When someone says that he has a good memory, he really

means that he keeps his memory in practice by using it. When someone else says that his memory is

poor, he really means that he does not give it enough chance to become strong. If a friend says that his

arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor

memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his

own fault. Have you ever found that some people can’t read or write but usually they have better

memories? This is because they cannot read or write and they have to remember things; they cannot

write down in a little notebook. They have to remember days, names, songs and stories; so their memory

is the whole time being exercised. So if you want to have a good memory, learn from the people:

Practice remembering.

1. The main reason for one is poor memory is that _______.

一、

Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find

out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until

the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.

246刍议高中英语阅读理解类题目的答题技巧 简阳中学 韩小英 【摘要】阅读理解类题目在英语试卷中所占的比重越来越大，分值越来越高。因此，学生必须重视英语阅读理解类题目，在平时的学习中积累阅读理解类题目的答题技巧。本文就高中英语阅读理解类题目的答题技巧做出讨论。 【关键词】高中英语仔细审题 通读全文 细节理解 词汇量 高中英语作为高考的重要学科之一，往往占有很大的分值比重，是学生战胜高考的一场关键性的战役。学生要充分重视高中英语这门学科，尤其要重视分值最高的阅读理解类题目，要从平时的学习中总结出一套适合自己的答题技巧。 高中英语试卷中的阅读理解类题目往往所牵扯的知识点有很多，而且很复杂，学生在做这类题目时往往会觉得比较吃力。其实这类题目的难度虽然大，但是也不是不可攻破的，只要学生寻找到解答此类题目的规律，就可以轻松应对英语阅读理解题目了。 一、仔细审题，从题目入手，通读全文，获取有用信息 阅读理解类题目的篇幅往往很长，而且单词数量多，因此，大部分学生反映，自己在做阅读理解的时候时间不够用，总觉得读了很长的文章最后只需要做五个选择题，这种做法很浪费时间。其实这个时候，老师可以教给学生一条不同于常规的做题方法，就是先读选择题题目，再读文章，带着问题通读全文能有效的节省时间。 高中英语试卷的题量较大，而答题的时间又不够充裕，很多学生都会在考试之后抱怨说自己又没有答完试卷，而没有答完的部分往往集中在题目难度较大，篇幅较长的阅读理解类题目上。大部分学生通常采取先读文章再答题的解题方法，这种方法确实有利于学生更加充分地理解文章，但是针对有时间限制的英语考试来说，这种方法可能就显得有些笨拙和守旧了。学生在通读一篇文章的基础上审题，在审题的过程中思考文章的内容，然后带着题目再次返回文章进行答案的寻找，这样的做法不知不觉地浪费了第一遍读文章的时间，这对于答题慢的学生来说是很不利的。 学生不妨换一条思路来解题，尝试运用先读题后读文章的方法进行阅读理解类题目的解答。例如，我们在阅读理解类题目中往往会遇到一些询问事件发生地点的题目，这时，学生可以先读题目，寻找出题目中所强调的具体事件，然后带着能表达关键性事件的关键词回到原文中，这样就可以轻松地从原文中获取到答案了。 因此，学生在碰到时间不够用的情况时，可以采取先仔细审题，然后获取题目中的关键词和关键句，带着这些关键词和关键句返回到原文中，通读全文获取答案。这种解答阅读理解题目的方法更加高效，耗时更少，效率更高。 二、瞪大眼睛，不放过任何能够表达细节类的关键词 高中英语试卷中的阅读理解类题目最常见的一种题型就是细节理解题，细节理解类题目所包含的题型又有很多种，例如推断作者观点、预测文章情节的走向、判断选项中与原文意思不相符的一项等等。这些题目的解答其实并不困难，只要求学生保持认真仔细的阅读态度，找到阅读理解类题目中的关键词，就可以轻松解决这类题目。 最常见的是推断作者观点或者立场的题目，这种题目的解题关键往往在于推断作者在文章的字里行间中透露出的语气。就需要学生在读文章的时候利用自己的火眼金睛，仔细寻找能够表达作者态度的关键词，寻找一些能够表达作者看法的标志性形容词。例如，作者在表达对文章中心事物的赞成时，往往会运用positive这一类褒义的积极性词汇，但是在表达对文章中心事物的反对时，则会运用一些消极的词汇，表达贬义的词汇。同时，学生在做推断作者观点类题目的时候，还要着重注意文章中的一些转折性词汇。例如，文章中可能在语句中体现however这样的转折性词汇，一旦发现这些词汇，学生就要提高警惕，判断是不是作者的观点要发生改变了。 学生在做判断细节的题目时，一定要注意文章中的关键词到底是哪些。在对判断选项中不符合原文意思的题目时，学生更应该瞪大眼睛，将选项中的语句与原文中的语句进行对比，找出不同的部分，判断两句话不同的部分是否具有相同的含义。这类题目的选项往往会设置很多错误的词汇，只是在原句的基础上修改一到两个词汇，这些词汇很有可能与原文想表达的意义相违背。 有些阅读理解类题目的判断主旨大意题也可能会与细节扯上关系，有些阅读理解类题目是具有某个寓意的故事，这个时候，学生需要在阅读文章中所描写的故事的同时，找到作者在文章中体现出来的关键词，反复出现的词汇往往就是这篇文章的关键词，往往能够表达出作者的写作意向和文章的主旨大意。 细节理解类题目的解题关键就是要找准题目中所涉及的关键词，找到关键词之后，学生就可以联系上下文，对全文的理解做出相应的判断。根据经验，老师可以为学生总结出一系列的表达立场的关键词，强调学生一定要留意文章中的表达转折的词汇。 三、多读英语的文章，提高阅读能力的同时扩充词汇量 英语阅读理解类题目与语文的阅读理解题相似，都是考察学生的阅读能力和对文章的理解能力。因此，学生在学习高中英语的过程中，也需要经常读一些英语的文章或杂志，养成良好的阅读习惯，提高自己的阅读能力。高中英语老师可以在课堂教学之余，带领学生读一些美文美句，让学生能够从这些美文美句中体会到英语的独特魅力，让学生能够在英语阅读的过程中养成良好的英语阅读习惯，进而提高学生对英语文章的理解能力。 阅读英语文章除了能够提高学生的阅读能力和理解能力外，同时还能够扩充学生的词汇量。学生在阅读英语文章的过程中，往往会遇到某些不认识的陌生词汇，这时，学生就需要查字典查出这些单词的意思，久而久之，学生在阅读过程中积累的单词就会越来越多，这对学生解答阅读理解类题目是非常有用的。 阅读理解类题目中经常会见到单词释义类的题目，就是在给出文章中的某个陌生词汇让学生进行词汇意义的判断。这类题目学生可以联系上下文，进行细节理解的推断得出答案，但是如果给出的陌生词汇学生恰好认识，这样的话就可以大大减少学生解题的时间，提高学生做题的速度和效率。 也有的学生反映，在阅读理解类题目中关于作者立场判断的题目中，给出的四个选项单词往往都比较复杂，不一定每次都能全部认出。这时，老师需要帮助学生总结出能够表达观点和立场的一些词汇，帮助学生记忆这些单词，扩大学生的词汇量。 综上所述，高中英语的阅读理解类题目其实并不困难，学生只需要掌握一定的解题方法和思路，就可以轻松应对了。

【典例探究】

（2010·山东卷·D）

Batteries can power anything from small sensors to large systems. While scientists are finding

ways to make them smaller but even more powerful, problems can arise when these batteries are

much larger and heavier than the devices themselves. University of Missouri(MU) researchers are

developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with high energy density(密度)”，said Jae

Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, presently

the size and thickness of a penny, intended to power various micro/nanoelectromechanreal

【导读】本文讲述了机器人苍蝇的研发，面临的困难以及前景。

A team of engineers at Harvard University has been inspired by Nature to create the first robotic

fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to

do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to

stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a

bunch of individual components(元件), ”said Robert Wood, the Harvard engineering professor

who has been working on the robotic fly project for over a decade. A few years ago, his team got

the go-ahead to start piecing together the components. “The added difficulty with a project like

this is that actually none of those components are off the shelf and so we have to develop them
