Language points
1. in common: for or by all of a group

6. Over time my memory has developed
so much that, ... I never forget anything
I have been told.
[考点] so ... that ... 引导结果状语从句。
[考例1] The weather was ______ cold
that I didn’t like to leave my room.
(2008 全国卷I)
A. really
B. such
C. too
D. so
7. And my memory became so large that
even I couldn’t believe it!
句型：so… that…
如此……以致于……
与 too…to… 句型的相互转换
And my memory became too large for me
to believe it.
eg He is so old that he can’t carry the box.
He is too old to carry the box.
此结构中的that从句表示结果。
The stone is so heavy that no one can lift it.
比较: so that 既可以表结果,也可以表目的。
so...that...结构的so+形容词/副词位于句
首时,句子用倒装结构。
So hard does he work that he seldom goes
home.
8. But I was always so lonely standing there
by myself, until in early 1960s they gave me
a family connected by a network.
[点拨] until表示“直到……时”，在肯定句
中，指从开始到结束的整段时间，谓语动词
一般是延续性的。在否定句中构成not ...
until，意为“直到……才”，指到某一点动
作才开始，谓语动词一般是非延续性的。其
强调句是it is (was) not until ... that ...。当
not until位于句首时，句子要进行倒装。
如：
The experts explored the island until the
end of last year.
直到去年年底，专家们一直都在勘查这个
小岛。
We didn’t solve the problem until Mr.
Smith helped us.
直到史密斯先生帮助我们，我们才解决了
那个问题。
It was not until last year that my hope
became a reality.
Not until noon did it stop raining.
9. I have also been put into robots and
used to make mobile phones as well as
help with medical operations.
1) help (sb) with sth 协助(某人)做某事
e.g. A man is helping the police with their
enquiries.
有一男子在协助警方进行调查。
2) as well as 也，还，而且
e.g. He grows flowers as well as vegetables.
She is a talented musician as well as
being a photographer.
3) 这个句子是现在完成时被动语态，其机
构是 (have/has +been + 过去分词）
e.g. The radio has been repaired when
we phoned the shop.
[考例1] Professor James will give us a
lecture on the Western culture, but when
and where ______ yet. (浙江2007)
A. hasn’t been decided
B. haven’t decided
C. isn’t being decided
D. aren’t decided
[点拨] 本题考查动词的时态、语态及主谓
一致。由yet可知要用完成时态，又因时间
与地点是被决定的，故应用被动语态。此
外，“在什么时候和什么地点（做报告）”
是指同一件事，故用单数形式。
[考例2] When you get the paper back,
pay special attention to what _______.
(四川2007)
A. have marked
B. have been marked
C. had marked
D. had been marked
[点拨] 因mark 这一动作发生在get之前，
且试卷是被批注，因此应用现在完成时
的被动语态。
10. anyhow 无论如何
Anyhow, you can try.
无论如何你可以试试。
I don’t care what you say; I’m going
to do it anyhow.
比较: somehow 意为“以某种方式;
不知 怎么地”
