九年级英语七-八单元重难点解析及同步练习(上)

一、疑点难点破解
1.For your next vacation，why not consider visiting Paris？下次度假，你何不考虑去巴黎呢？

疑点：1)Why not do…是why don’t you do…的省略形式，常用来表达建议或邀请。

如：Why not go to the Summer Palace for our vacation？为什么不去颐和园度假呢？

难点：英语中表示建议的方式还有许多，学习中要仔细区分。

如：Would you like to go hiking with us at weekend？

Shall we have a walk after supper？

Let’s go shopping.

How about/ What about playing basketball instead？

疑点：2)consider doing sth.考虑做某事

如：I first considered calling him，then I gave up.开始我考虑给他打电话，后来放弃了。

难点：consider 的后面可以跟多种结构，都用来表示“考虑、细想”之意。如:consider sb./sth.+宾语补足语；consider sb. to be +宾语补足语；consider+从句

如：I considered him my best friend./Tom considered this answer wrong.

I considered her to be a clever girl./ I considered that she was a clever girl.

2. I’d like to trek through the jungle，because I like exciting vacations.我要到丛林里去长途旅行，因为我喜欢刺激的度假方式。

疑点：trek through意思为“从…中穿过、在…中长途跋涉”

如：During the Long March，all the soldiers trekked through the jungles and grass，at last they succeeded in getting to the destination.

难点：through和across都有“穿过、通过”的意思across表示某一动作是在某一物体的表面进行；through表示动作发生在立体空间，四面八方都有东西。

如：I swam across the river.They walked through the forest.

3.And quite a few said they dream of going to the moon one day.许多人说他们梦想有一天会登上月球。

疑点：few意为“几乎没有几个”，表示否定；a few表示“有些、几个”，表示肯定；quite a few=many表示“许多”。

如：I have eaten quite a few apples today.=I have eaten many apples today.

难点：quite a little=much表示“许多”，修饰不可数名词。

如：Fat persons often eat quite a little meat.

4.We need to come up with a plan.我们需要做出个计划。

疑点：句中的need是实义动词，表示“需要”，后接动词不定式。need后面也可跟V-ing，表示“某事需要被别人做”。

如：I need to go there as quickly as possible.我需要尽快去那儿一趟。

My bike needs mending .我的自行车需要修理了。

难点：在否定句和疑问句中，need还可以用作情态动词，后接动词原形。

如：I needn’t tell him the bad news.=I don’t need to tell him the bad news.

5. Not only do I feel good about helping other people，but I get to spend time doing what I love to do.不仅我觉得帮助别人是好的，而且我还将时间花在做我喜欢做的事情上。

疑点：not only…but also意为“不但…而且…”，是一组并列连词，连接两个相同的句子成分或两个句子。连接两个句子时，当not only位于句首时，第一个分句要到装。

如：Not only do I know his name，but also I know his father’s name.

难点：如果not only…but also…连接两个主语时，谓语动词要与邻近的一个保持一致。

如：Not only his parents but also he speaks Japanese well.

二、重点讲解
1.provide sb. with sth.;provide sth. for sb.向某人提供某物，供给

如：My parents provide me with food and drink.

This firm provided a big house for the old man.

Provide还可以构成如下短语：provide for sb.供给某人生活所需；provide for sth. 为某事可能发生做准备；provide against sth.防备发生某市、预防某事

2.a number of 与the number of的区别

a number of 相当于some，a few; a great/large number of相当于many，quite a few; the number of指的是“…的数量”。

如：The number of the students in our school is 5，000. A number of them are going to study in the university.

3. According to the survey，the most popular choice of job is computer programming.

according to表示1)根据所说、所示；2)随…而作变更

如：According to Tom，the English teacher is really a good teacher.根据Tom的说法，英语老师是一位真正的好老师。

According to the amount of work we do，we will be paid.

我们的报酬随工作量而定。

4. For sure，you have helped make it possible for me to have “Lucky”，…

for sure相当于without doubt无疑

如：I think he lived in Shijiazhuang，but I can’t say for sure.

我想他是住在石家庄，但是我不敢肯定。
三、语法展示
(一)关系副词引导的定语从句

1、关系副词在从句中分别表示时间、地点或原因。关系副词when在从句中充当时间状语，where 充当地点状语，why充当原因状语。即where在从句中作地点状语，其先行词是表示“地点”的词。本单元主要学习where的用法

2、where在定语从句中的作用。where在定语从句中做地点状语，它的先行词必须是表示地点的名词。如：

1). I like places where the weather is always warm.=I like places in which the weather is always warm.

2). Have you been to the small village where you were born？=Have you ever been to the small village in which you were born？

(二)短语动词

在英语学习中，较难掌握的是动词，而动词中，最难掌握的莫过于短语动词了.然而，在各类英语考试中，总有几道与短语动词相关的试题，每每令应试者束手无策。

1、短语动词的构成：英语中的动词，按其构成，可分为单词动词(single-word verb)和短语动词(phrasal verb).短语动词指由两个或两个以上单词构成的动词.这种动词主要有三种组合形式：

1).动词 + 介词 I agree with(与......看法一致)，take after(长得像…)，hear from(受到某人的来信)，pay for(赔偿)，stand for(代表、表示)

2).动词+副词 cheer up (使振奋、使高兴)，set up(建立、创立)，put up(举起、张贴)，give away(捐赠、分发)，give out(发放、消耗尽)，work out(算出)

3).动词+副词+介词 go in for (喜欢)，put up with (忍受)，come up with(想起)，catch up with (赶上、跟上)，look down upon(看不起)，run out of (耗尽、永光)。

在“动词+副词+介词”的组合中，短语动词只能看作是一个动词，绝对不能拆开。另外，还需要注意的是，以上三类短语动词都是一些固定搭配，这些短语动词与某些非固定搭配是有区别的，试比较： (1)The lights went out. (2)He put on his coat and went out.

例(1)中的went out(熄灭)是由“动词+副词”构成的短语动词。例(2)中的went out(出去)不是短语动词，went 是动词，out是副词，作状语。

4).动词+名词+介词catch sight of(看见) draw one’s attention to(吸引……注意) make fun of(取笑) make use of(利用) take care of(照顾) take part in(参加) lose sight of(看不见) make friends with(与……交友 )take(catch，get) hold of(抓住) take notice of(注意到)

2.及物与不及物短语动词。由动词和副词构成的短语动词有的起及物动词的作用，有的起不及物动词的作用。短语动词是及物的还是不及物的主要取决于短语动词的意思。因为，一个短语动词可能具有两个或几个不同的意思，用作某个或某几个意思时可能是及物的，用作别的意思时又可能是不及物的。

如：He took off his coat when he entered the house and put it on again when he went out. (take off 是及物短语动词)

At airports people can watch the planes taking off and landing. (take off是不及物短语动词)

3.物短语动词宾语的位置。

1).名词宾语通常位于这种短语动词之末。

如：I am looking for my glasses.

2).个别短语动词，其名词宾语必须放在动词和副词之间，不能放在短语动词之后。

如：I am going to see the guests off at the airport this afternoon.

3).对有些短语动词来说，名词宾语既可放在整个短语动词后面，也可放在动词和介词或副词之间。

如： We’ll have to put off the party. 或者We’ll have to put the party off.

4).代词宾语有时位于短语动词的词尾。

如：I am looking into it.

5).代词宾语更常紧跟在动词之后，代词宾语的这个位置常见于下列介词或副词之前：away，down，in，off，out，up.

4.及物短语动词后接动词宾语的问题。

1).及物短语动词后接动词宾语时，要用该动词的动名词形式。

如：He insisted on buying this car.

2).有些短语动词后面可接不定式。

如：Most of the members called on the mayor to resign.

3).有的短语动词既可接动名词又可接不定式，但意思差别很大，go on doing 和go on to do就是典型的例子。
