九年级英语七-八单元重难点解析及同步练习

　　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.
