四、句式点击
1．What problems do you think people in the future will have overcome?
此句为复杂疑问句，其句式结构为：疑问词+do you think+其余部分(其余部分为陈述语序),do you think 为插入语。

能用于此句型的动词有：think，believe，suppose，imagine，suggest，expect等。

e.g: Who do you think is the tallest in your class? 你认为在你们班谁最高?
[注意]
1)如果此句型的动词后面的从句里有否定意义，往往要把否定前置。

如：
I don't think it’s right to do so．我想这样做是不对的。

2)该句型变反意疑问句，主句主语是第一人称时，反问部分与从句一致，否则与主句一致。

①I think that he has been to Beijing, ?
②He thinks that their team are sure to win the game, ?
2. I got lost when we reached the place that looked like a large market because of the people flying by in all direction.
该句含有一个that引导的从句，that在从句中作，flying by in all direction是现在分词短语作, 修饰。

3. ...some chairs rose from under the floor as if by magic ……一些椅子就像变魔术一样从地板下面升
了起来。

注意：from后面有时可接介词短语或where从句。

from under the floor 从地板下面
拓展：from behind the door 从门后面
from under the table 从桌子底下
His head soon appeared out of the window, he saw nothing but trees.（2010·山西大同检测）
A. Where
B. which
C. there
D. from where
4. However, I lost sight of Wang Ping when we reached what looked like a large market because of too wany carriages flying by in all directions. 然而，当我们到达一个看上去像是大市场的地方时，由于太多的客车朝四面八方飞奔，我看不见王平了。

what looked like... 是，做reached 的宾语。

what 在宾语从句中做，表示地点。

这时，同学们要注意，别把what 误用做where，因为where是连接副词，在从句中做地点状语，而what 是连接代词，在从句中做主语、宾语、表语或定语。

what 引导名词性从句时，常含有事情、状况、言语、时间和地点的意味。

如：
①What surprised me most was his way of speaking.
最让我吃惊的是他的说话方式。

(what 表事情)
②She is no longer what she used to be.
她不再是以前的样子了。

(what 表状况)
③We were all confused by what he said.
我们都被他说的话弄迷糊了。

(what 表言语)
④He had driven for what seemed three hours.
他开车开了似乎三个小时了。

(what 表时间)
⑤They finally reached what was called “a lonely island”．
他们终于来到了一个叫“孤岛”的地方。

(what 表地点)

remind sb. of sth.=remind sb．about... 提醒某人某事；remind sb. to do sth. 提醒某人做某事

六、语法天地（过去分词用作状语和定语）
（一）过去分词作状语
过去分词作状语可表时间, 原因, 让步, 结果, 方式, 条件等，过去分词作状语要符合两个条件：（1）主语一致，即分词的逻辑主语必须是主句的主语。

（2）分词和主句的主语之间是被动关系。

过去分词作时间状语
1. When it is heated, ice will be changed into water.
→When heated, ice will be changed into water.
2. When it is seen under a microscope, a fresh snowflake has a delicate six-pointed.
→Seen under a microscope, a fresh snowflake has a delicate six-pointed shape.
过去分词作原因状语
1. Since/ As she was given advice by the famous detective, the young lady was no longer afraid.
→Given advice by the famous detective, the young lady was no longer afraid.
2. Because it was done in a hurry, his homework was full of mistakes.
→Done in a hurry, his homewor k was full of mistakes.
过去分词作条件或者假设状语
1. If we are compared with you, we still have a long way to go.
→Compared with you, we still have a long way to go.
作方式或伴随情况状语
1.The hunter left his house, followed by his dog.
→The hunter left his house, and he was followed by his dog.
2. She sat by the window, lost in thought.
→She sat by the window, and she was lost in thought.
小结：综合以上可以看出，过去分词作状语和状语从句之间是可以相互转化的，方法是: 把状语从句中的连词，主语和系动词be去掉，直接以过去分词开头就变成过去分词作状语了。

练习：用过去分词作状语来改写句子。

①As I was worried about the journey, I was unsettled for the first few days.
→ _______________________ , I was unsettled for the first few days.
②If he is given time, he’ll make a first-class tennis player.
→ _________ , he’ll make a first-class tennis player.
③As I was confused by the new surroundings, I was hit by the lack of fresh air.
→______________________________, I was hit by the lack of fresh air.
④When he was questioned by the police about the fire, he became tense.
→ , he became tense.
