二、重点句型
1. Justin did in fact return home on Friday night at about 11p.m.
do 放在谓语动词前表示强调，“的确，一定”．
［注意］人称，事态的变化体现在do上，后面动词用原形．
He did tell us all that had happened.
Do be careful.
2. They saw Justin walking towards his home. 感官动词＋ sb. + doing（片断）
I heard him put on his favourite CD. 感官动词＋ sb. + do（全过程）
I heard him singing an English song.我听见他在唱一首英文歌曲．
I heard him sing an English song.我听见他了唱一首英文歌曲．
I saw him cleaning the blackboard.我看见他在擦黑板．
I saw him clean the black board.我看见他擦了黑板．
3. (1) There were many windows.
③ ② ①
here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell. Here is your letter.
(2) Standing inside were lots of white-skinned, strange- looking creature with large black eyes.
③ ② ①
为了保持句子平衡，避免头重脚轻，表语或宾语提到句首，进行完全倒装。
Behind him walked the team wearing black and white suits.
③ ② ①
[注意] 全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。
Here he comes. Away they went.
4. it is possible that the man-like creature is an unknown animal.
It is possible to do /that…很可能…
It 在句中是形式主语，后面的to do不定式或that从句是真正主语。
It is possible for him to make rapid progress.
It is possible that I will win the prize.
She is possible to be in London this year.
5. Yeti is said to be heavily built and hairy.
(1) Sb/sth is said to do sth…据说某人或某物做某事
He is said to be the brightest man in the world.
=people say he is the brightest man in the world.
常使用的句型还有sb/sth is hoped/ thought/ believed/ known…to do
We are hoped to make progress everyday.
(2)It is said that…据说…
其中It 是形式主语,that引导的从句是真正的主语.
It is said that he is the brightest man in the world.
It is hoped that we can make progress everyday.
6. He became convinced that they exist while (he was) studying the footprints.
while引导从句时,如主、从句的主语一致,且从句谓语又含有be,则从句主语和be可省略
While (she was) listening to the radio, she fell asleep. 她在听收音机时睡着了。
While (he was) in London, he studied music and painting. 在伦敦时,他学习音乐和绘画。
while I was reading a book, someone called me outside.
三、语法：现在完成时&现在完成进行时
1. 现在完成时：have/has + done
△……………………………………△
过去 现在
1)现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。
[注意]常与现在完成时连用的几个副词：already，just，ever，yet，never等。
★ already，just多用于肯定句;
★ ever，yet，never多用于疑问句和否定句。如：
2)表示过去已经开始，一直持续到现在的动作或状态。
使用的时间状语通常由for或since 引导，但二者后接的词有所不同：
★ for+一个时间段，指某个动作到现在为止已持续了多长时间，如for three years, for half an hour等.
★ since+具体时间，表示动作或状态从何时开始，如since 1980，也可以接“since three years ago, since two months ago等。 ”,
[注意]瞬间动词不能直接和for 或since 连用，但我们可以找一个相应的延续性动词或动词短语来替换这些非延续性动词，如:
come →be, go out→ be out, leave →be away,
begin / start →be on, stop→ be over，
open →be open, close →be closed,
join →be a member of,
die →be dead,
get to know →know,
get married →be married
become a teacher →be a teacher,
catch a cold →have a cold,
fall asleep →be asleep, fall ill→ be ill
3)have been to/have gone to /have been in 三者区别：
have (has) been to意为“曾经去过某地”，表示现在已经不在那里了;可与just, ever, never等连用。
have (has) gone to意为“到某地去了”，表示到了某地或正在去某地的途中，说话时该人不在现场。
4）用于现在完成时的其它时间状语：
除了我们讲过的already, yet, still，just, ever, never, since短语和 for短语外，还有许多时间状语常用于现在完成时，我们要留心将它们和一般过去时的时间状语区分开来：
★lately, recently是完成时的时间状语；
just now 是过去时的时间状语。如：
Have you heard from your family lately/recently?
Did you see Joan just now?
★in the past few years 意思是“过去几年来”，常用于完成时中；
in the past意思是“在过去”，常用于过去时中。 如：
Great changes have taken place in my hometown in the past few years.
Where did you work in the past?
★ever since then与from then on / after that 都有“打那以后”之意，
但前者常用于完成时，而后两者常用于过去时。如：
She‘s lived here ever since then.
I didn't hear of Jim from then on/after that.
★before 通常用于完成时；
...ago通常用于过去时。如：
I have never been to Japan before.
She went to Japan two years ago.
★ so far“到目前为止”， these days“这些天来”也是现在完成时常见的时间状语。如：
So far, no man has travelled farther than the moon.
What have you done these days?
5）用于现在完成时的典型句型：
★句型It is the first （second, third...) time that...的that从句中，谓语动词须用现在完成时，表示到说话时为止动作发生过几次。如：
It is the first time that I have been here.
★句型It is the best/most interesting … that...的that从句中，谓语动词须用现在完成时,表示说话为止这是最好/有趣…的人或物.
You are the brightest student that I have ever taught.
2. 现在完成进行时：have/has + been + doing
△……………………………………△………
过去 现在
1）表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去。
2）现在完成进行时可以表示不间断动作，而现在完成时表示间断动作的重复。
3）how many or how much(次数)对现在完成时提问; 而how long可以对现在完成进行时提问。
4）有些时间状语不能用于现在完成进行时,如:never,yet,already,ever.
