初三英语重点难点解析

初三英语重点难点解析

REPORT”进行练习。

一、提出建议并能作出恰当的回答

在第二册第６单元已经学到过用“shall”，“Let’s”和“why not”来提出建议，并作简略回答。

如：

①-Shall we go at ten?

-Good idea!

②-Let's go at ten?

-OK!

③-Why not go at ten?-All right.

这一单元里，主要学习有关“had better”的用法。“had better＋动词原形”表示“最好做某事”，用来向别人提出建议，其形式可以缩写为“d better”。如：

①You'd better do your homework now.

②We'd better go to school.

“had better”的否定形式为“had better not…”如：You'd better not watch TVnow.

二、学习过去进行时的各种句式

在前一单元里，已经学习了过去进行时的构成和用法，这一单元着重学习它的否定句式、一般疑问句式及在从句中的用法。

１．过去进行时的否定式在助动词“be（was或were）”后面加上“not”即可。如：

I was not washing clothes last night.

２．过去进行时的一般疑问句式为：助动词“was或were”在句首。

如：

—Was Tom writing a letter at seven yesterday?

—Yes,he was.(No,he wasn't.)

３．在含“when”和“while”（当……时)引导的时间状语从句的复合句中，常有过去进行时，表示一个动作在过去某一时刻或一段时间内正在进行或发生。这一过去进行时的动作可以出现在主句，也可以出现在从句中，但要注意的是，用该时态的动词常常是一个持续性动词。如：

①Someone knocked at the door when I was cook-ing

② While we were talking，my mother came in.

③ The twins were sweeping the floor when their mother returned.

另外，含“when”的复合句中，主句用过去进行时，从句用一般过去时的情况下，常包含有“意外”之概念，如前例③。

三、重点、难点词组和句子的分析

1. You look tired today. (

2.17)（你看上去很累。）

该句中的“look”意为“看起来”，是系动词，而在这种系动词后面常用形容词作表语如look young/hap y/old/…等，另外，“look”也可用作实义动词，并且有许多相关词组，如：look at …（看…）look like… （看起来像……），look the same（看起来很相像），look for…（寻找……），look after…（照料/照看……）等等。当然，不能再用形容词来作表语或修饰它，如果要修饰，只能用副词。如：

Please look after your watch carefull.

2． A woman saw it happen when she was walking past．(L17)

表示感觉的动词如“see，hear，watch”等以及一些其它动词如“make，let”等，后接不定式作其宾语补足语时，该不定式前不带“to”。如：

①I’m tired．Let me have a short rest．

②Do you often hear Tom sing this song?

③I saw him go out．(我看到他出去了。)

另外,“see，hear，watch”等还可后接现在分词作其宾语补足语。如：

I heard someone laughing. (我听到有人在笑。)

3．The children were leaving school on Tues-day when they saw a truck． (2．18)

该句中有二点需要注意：

①“were leaving”是过去进行时的形式表示过去将来的动作，即“正要离开……”。在英语中，个别动词如：“leave，go, come，start”等，它们的进行时形式可以表示一个最近按计划或安排要进行的动作。如：

Are you going home next week?

②“leave school表示“(学生)离校；毕业”；中间不加冠词。又如；go to school／come to school( 上学)。类似的表达法如： in

hospita1(住院)，leave hospital／come out of hospita1(出院)。注意比较下句中冠词的区别；

His mother often goes to ____the school to seeher son at

______ school.

4.He did not see the bag until it was too late: (L18)

“not…until…” 是“直到……才……”如:

①. She won.'t go away until you promise, to help her.

②. I didn't go home until I finished cleaning the classroom.

5. It's really nice of you. (L18)

该句相当于“It's very kind of you.”（你真好。）

6. He told her about the accident. (L18) “tell sb. about/of sth.”意为：“告诉某有关某事或跟某人讲述某事”。如：

Please tell me about your family.

另外, “tell sb. sth./tell sth. to sb.” “告诉某人某事”，“tell sb. todo sth. ”：“叫某人做某事”。如：

① I told him my name.

② My grandfarther often told us stories when we were children.

③ She told the happy news to everyone.
