Section B

There are three kinds of goals: short-term, medium-range and long-term goals. Short-range goals are those that usually deal with current activities, which we can apply on a daily basis. Such goals can be achieved in a week or less or two weeks, or possible months. It should be remembered that just as a building is no stronger than its foundation, out long-term goals cannot amount to very munch without the achievement of solid short-term goals. Upon completing our short-term goals, we should date the occasion and then add new short-term goals that will build on those that have been completed.

The intermediate goals are based on the foundation of the short-range goals. They might deal with just one term of school or the entire school year, or they could even extend for several years. Any time you move a step at a time, you should never allow yourself to become discouraged or overwhelmed. As you complete each step, you will enforce the belief in your ability to grow to succeed. And as your list of completion dates grow, your motivation and desire will increase.

Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not

a static thing. We should never allow a long-term goal to limit us or our course of action.

1. Our long-term goals mean a lot______.

A. if we complete our short-range goals

B. if we cannot reach solid short-term goals

C. if we write down the dates

D. if we put forward some plans

2. New short-term goals are built upon______.

A. two years

B. long-term goals

C. current activities

D. the goals that have been completed

3. When we complete each step of our goals, ______.

A. we will win final success

B. we are overwhelmed

C. we should build up confidence of success

D. we should strong desire for setting new goals

4. Once our goals are drawn up,_______.

A. we should stick to them until we complete them

B. we may change our goals as we have new ideas and opportunities

C. we had better wait for the exciting news of success

D. we have made great decision

5. It is implied but not stated in the passage that ______.

Section C

01. Array ____

____

P

arent

s are

often upset when their children praise the homes of their friends and regard it as a slur on their own cooking, or

cleaning, or furniture, and often are foolish enough to let the adolescents see that they are annoyed. They may

even accuse them of disloyalty, or make some spiteful remark about the friends’ parents. Such a loss of dignity

and descent into childish behavior on the part of the adults deeply shocks the adolescents, and makes them resolve

that in future they will not talk to their parents about the places or people they visit. Before very long the parents

will be complaining that the child is so secretive and never tells them anything, but they seldom realize that they

have brought this on themselves.

02. ________

Disillusionment with the parents, however good and adequate they may be both as parents and as individuals,

is to some degree inevitable. Most children have such a high ideal of their parents, unless the parents themselves

have been unsatisfactory, that it can hardly hope to stand up to a realistic evaluation. Parents would be greatly

surprised and deeply touched if they realized how much belief their children usually have in their character and

infallibility, and how much this faith means to a child. If parents were prepared for this adolescent reaction, and

realized that it was a sign that the child was growing up and developing valuable powers of observation and

independent judgment, they would not be so hurt, and therefore would not drive the child into opposition by

resenting and resisting it.

03. ________

The adolescent, with his passion for sincerity, always respects a parent who admits that he is wrong, or ignorant, or even that he has been unfair or unjust. What the child cannot forgive is the parents’ refusal to admit these charges if the child knows them to be true.

04. ________

Victorian parents believed that they kept their dignity by retreating behind an unreasoning authoritarian

attitude; in fact they did nothing of the kind, but children were then too cowed to let them know how they really felt.

Today we tend to go to the other extreme, but on the whole this is a healthier attitude both for the child and the

parent. It is always wiser and safer to face up to reality, however painful it may be at the moment.

Section D

Education is not an end, but a means to an end. In other words, we do not educate children only for the

purpose of educating them .Our purpose is to fit them for life.

In some modern countries it has for some time been fashionable(时兴的)to think that by free education for

all--whether rich or poor , clever or stupid --one can solve all the problems of society and build a perfect nation.

But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees ,they refuse to do what they think "low "work and , in fact ,work with hands is thought to be dirty and shameful in such countries .But we have only to think a moment to understand that the work of a completely uneducated , farmer is far more important than that of a professor, we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns...

In fact, when we say that all of us must be educated to fit us for life , it means that we must be educated in such a way that , firstly each of us can do whatever work suited to his brains and ability and , secondly that we can realize that all jobs are necessary to society , and that is very bad to be ashamed of one's work . Only such a type of education can be considered valuable to society.

1. What is the purpose of education in the passage?

2. According to the passage, what is the wrong attitude of some people with university degrees?

3. The writer wants to prove that our society needs ___________________________ jobs.

4. The passage tells us about the ________________________________________ of education

Bicycles are a convenient means of transportation. People can go wherever they like by bike on a short trip. It is easy to go to work or school by bike because most of the Chinese live not far away from where they work or study. Riding bicycles is also good exercise, which can help build people's bodies.

What's more, riding bicycles can save energy. China has a population of more than 1,300 million. As bicycles are not expensive, almost every family has one. Now each family in China has at least a bike instead of a car. Thus a great deal of energy is saved and serious air pollution is reduced. That's why bicycles are so popular in China

(二)、“as” as, when, while都有“当……的时候”,可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词,常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问,连接并列分句。When表示“就在……的时候”, while意反而,可是,表示转折。

高考状语从句讲解

As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长,我们用力量换来了机敏,以速度换来了严谨,以热情换来了理智。 注:1)when还可作并列连词,其意义为“那时,这时”,相当于and at this/that time。常用于下列句式: sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作,而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时,when,while 与as可互换使用。如: When/While/As I was walking down the street,I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句:主句的谓语是延续性动词,主从句均为肯定式,意为“某动作一直持续到某时间点才停止”

中考状语从句讲解及练习

状语从句 状语从句用来修饰主句中的动词,副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句,地点状语从句,条件状语从句,原因状语从句,结果状语从句,比较状语从句,目的状语从句,让步状语从句。 1. 时间状语从句 (1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如:It was raining hard(rain hard 下大雨)when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along(沿着走)the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里,通常不用将来时态,用现在时态表示将来的动作或状态。例如: I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是“一直到……时”,谓语动词只能用延续性动词。如果主句用否定式,其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如: The young man read till the light went out(熄灭). Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off(从下来)until the bus stops. 【Till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。Until 是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。固定组合里from morning till night,till/until是不能替换的,】2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如: What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. (2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。例如: I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如:Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如: He didn’t come to school because he was ill. As it is raining, we shall not (不得;不应该)go the zoo. Since you can’t answer the question, I’ll ask someone else. (2)because表示直接原因,语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题,只能用because。As和since语气较弱,一般用来表示明显的原因。由as 和since引导的原因状语从居多放在句首。例如: ------Why aren’t going there?

状语从句讲解及练习

状语从句 在复合句中担任状语成分的从句称为状语从句,修饰主句的谓语动词,形容词或副词,状语 说白了就是修饰动作的词或句,也可以理解成修饰谓语的词或句。通常由副词、介词短语、 动词不定式、分词和从句等担当。例如: 1. Naturally, our grandparents were pleased to get our phone call. (副词 ) 2. We worked hard, from sunrise to sunset. (介词状短语 ) 3. To help my disabled aunt, I spend an hour working in her house every day. (不定式 ) 4. Seen from a distance, the farmhouse looked deserted. (过去分词 ) 5. I know how to light a camp fire because I had done it before .(原因状语从句) 状语的位置比较灵活,可以位于句首、句末或句中。enough 用作状语修饰形容词和副词时 必须后置。 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多,但由于状语从句与汉语结构和用法 相似,所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点。现分别列举如下: 1.时间状语从句 常用引导词: when, as, while, as soon as, while, before, after, since , till, until 特殊引导词: the minute, the moment, the second, every time, the day , the instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点: when 从句的主语与主句主语相同,谓语动词是be 动词时,从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”,还可表示为“一面``` 一面”,“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生,从句一般用进行时, 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点: while 有对比的含义,解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1.until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词;在否定句中主句常用短暂性动词。
