3.句式点击：

⑴At first my new surroundings were difficult to tolerate.

开始的时候，新的环境让人难以忍受。

本句型为“主语+be +adj.+ to do”不定式用于形容词后作状语，其逻辑宾语为句子主语，但不定式要用主动形式表示被动含义。若其中的动词为不及物动词，则应在其后加相应的介词。如：

These programs are usually easy to receive.

这些节目通常容易接收到。

The box is heavy to carry.

这个箱子搬起来很重。

注意：该句型的主语可以是人，也可以是物。用于此句型的形容词有easy, hard, comfortable, difficult, heavy等。

⑵However , I lost sight of Wang Ping when we reached what looked like a large market

because of too many carriages flying by in all directions.

然而，当我们到达一个看上去是大市场的地方时，由于气垫车朝四面八方飞奔，我看不见王平了。

①what looked like a large market 是一个由what 引导的宾语从句，what在句中做主语

。在这句话中what=a place that

②in all directions 向四面八方

⑶Then Wang Ping flashed a switch on a computer screen, and a table and some chairs rose

from under the floor as if by magic.

然而王平在电脑荧屏上的开关闪了一下，于是一张桌子和几把椅子就像变魔术似的从地板下面升了起来。

①from under the floor 从地板下面

②as if by magic 像变魔术那样

as if = as though “似乎，好像”引导方式状语从句

⑷Hit by a lack of fresh air, my head ached.

由于缺乏新鲜空气，我感到头痛。

过去分词hit 在句中做状语，表示与主句中动作伴随发生的情况，相当于一个状语从句。

hit by---= Because I was hit by----

课文中类似的句子还有

___________________________________________________________________________ ______________

___________________________________________________________________________ _____________

⑸Inside was an exhibition of the most up-to –date inventions of the 31st century.

里面陈列着31世纪的最新发明。

这是一个完全倒装句，句子的真正主语是an exhibition.

表示方位的副词或介词短语，如here, there , up, down, in, away, off, out, 等置于句首时，常引起完全倒装。

eg. Out rushed the children. 孩子们冲出去了。

In front of the house stands a tall tree. 在房子的前面有一棵大树。

三．语法分析：

过去分词作定语和状语

1. 过去分词作定语

过去分词作定语时，和所修饰的中心名词之间存在被动关系，可以转化成一个定语从
