重要知识点讲解

Section A_Grammar Focus_Section B_综合

Section A

一、介词by的用法

By working with friends.通过和朋友合作。 [点拨]

\"by\"是介词,意为“通过,靠”;

此处表示方法、手段,后接名词或代词; 接动词时,须用动名词形式。

可用来回答how引导的特殊疑问句。 by作为介词的意义有很多; 1)在...旁边,靠近

There is a power station by the river. 河边有一个电厂。 2)沿着,经由

to enter by the door 由门进去 3)由于

by mistake 由于差错;错误地

4)被,由

some articles written by Lu Xun 一些由鲁迅写的文章 5)表示相(乘)除(以计算面积)

a room 5m by 4m 一个长五米宽四米的房间 6)逐一;连续

one by one 一个接一个

二、too...to结构

It's too hard to understand the spoken English.口语太难了,不能理解。 [点拨]

“too + 形容词/副词+to+动词原形”意为“太...而不能...”;该句型用于肯定句,但表示否定的意义。

too…to…前面有never,not,only,but等词时,或出现too …not to do的双重否定时,否定词与不定式中的否定意义结合起来构成了肯定意义。 如:It’s never too old to learn.活到老,学到老。

三、so...that结构

1.The teacher spoke so quickly that I did not understand her most of the time.老师说得如此快,以致于大多数时间我不能理解她说的。 [点拨]

\"so+形容词/副词+ that+句子\"是固定句式,意为“如此...以致于...”。 若so位于实义动词后,so后面就用副词。

Grammar Focus

一、询问对方如何做某事的句型

-How do you learn English?你是怎么学习英语的? -I learn by studying with a group.我通过和一个组学习。 [点拨]

\"How do you+动词原形+sth?\"英语询问对方如何做某事。 该问句的回答:I+动词原形+by+名词短语/动词的现在分词短语.

二、询问对方是否通过某种方式来做某事的句型

-Do you learn English by reading aloud?你是通过大声朗读来学英语的吗? -Yes,I do.It helps my pronunciation.是的。提高我的发音。 [点拨]

\"Do you+do sth+by+动词的现在分词短语?\"用于询问对方是否通过某种方式来做某事。该句是一个一般疑问句。因此回答遵循一般疑问句的回答即可。

三、询问对方该如何做某事的句型
