Important sentences
重点知识归纳 第三部分：课文重要句式
1 What 引导的名词性从句，用陈述语气
Do you know what these disasters are （教材P48，宾语从句)
What impressed me most was his bravery. （主语从句）
What ≈ 名词+定语从句连接词
如 What impressed= Something that impressed me
2. It seemed as if the world were coming to an end. （教材P50， 虚拟语气)
as if =as though “好像”，在seem后引导表语从句。
(1) 如果as if/though所引导的从句表示的情况是真实的或是极有可能发生的情况时，句子用陈述语气。
eg. It looks as/though you are ill today. （陈述语气）
(2) 当说话人所陈述的是不真实的或极少可能发生或存在的情况时，从句用虚拟语气，从句的谓语动词用法如下：
与现在事实相反：一般过去时did/were
eg. He treats his students as if they were his own sons and daughters.
as if 引导的表语从句
教材 P50 It seemed as if the world were coming to an end! 仿佛世界末日即将来临！
as if 意为“仿佛，好像”，相当于 as though。as if 可置于look, seem, feel 等连系动词后引导表语从 句，也可以引导方式状语从句。
（1）as if 引导的从句常用虚拟语气，表示从句所述的情况不是真实的或极少有可能发生或存再。具体用法如下:
She talks as if she knew all about it.
Tom kept working as if nothing had happened.
(2)as if引导的从句所述的情况为客观事实或极有可能发生，则用陈述语气。
It looks as if we will be late. 我们似乎要迟到了。
(3)as if引导的从句有时可用省略形式，其结构为:as if+名词/不定式/分词/介词短语等。
He acts as if (he were) a fool. 他做事像个傻瓜。
Mike looked as if (he was) in search of something. 迈克看起来好像在寻找什么东西似的。
练习: 1)He talks as if he ________(know) everything in the world.
2)The clouds are gathering. It looks as if it _______(be) going to rain.
knew
as if+从句 一般过去时(与现在事实不符)
过去完成时(与过去事实不符)
would/ could/ might+动词原形(与将来事实不符)
is
3 “百分数/分数+of+名词或代词”做主语，谓语的单复数由of 后面的名词决定。
eg. Over 70 percent of the surface of the earth is covered with water.
40 percent of the workers are married women; the rest are single.
4 I was having breakfast with my three children when water started filling my home.(教材P54)
我正和三个孩子一起吃早餐，突然家里开始充满了水。
sb. was/were doing….when… 某人正在做……这时……
sb. was/were about to do… when… 某人将要做……这时……
be doing sth. when...正在做某事,这时……
when用作并列连词常用于下列句型中:
①sb. sth. when...
某人刚做完某事,这时(突然)……
②sb.
/ sth. when...
某人正要做某事,这时(突然)……
③sb. sth. when...
某人正在做某事,这时(突然)……
had(just) done
was/were on the point of doing
was/were about to do
was/were doing
5. 不定式用主动形式表示被动意义
教材P50 Water, food, and electricity were hard to get. 没有水和食物，电也停了。
句式分析:主语(water, food, and electricity)是不定式(to get)的逻辑宾语,因此不定式后不能出现宾语。
（1）如果不定式中的动词为不及物动词，则其后要接相应的介词。
This kind of paper is not hard enough to write on.
（2常用的形容词有：easy, difficult, hard, interesting, pleasant,
comfortable, impossible, safe, fit, dangerous等
The book is difficult to understand. 这本书很难理解。
（3）变式： It+ be+ adj.+不定式（含宾语）
The man is easy to get along with. It is easy to get along with the man.
练习：The question is difficult for such a little boy _________(answer).
to answer
Thank you !

Important sentences
重点知识归纳 第三部分：课文重要句式
1 What 引导的名词性从句，用陈述语气
Do you know what these disasters are （教材P48，宾语从句)
What impressed me most was his bravery. （主语从句）
What ≈ 名词+定语从句连接词
如 What impressed= Something that impressed me
2. It seemed as if the world were coming to an end. （教材P50， 虚拟语气)
as if =as though “好像”，在seem后引导表语从句。
(1) 如果as if/though所引导的从句表示的情况是真实的或是极有可能发生的情况时，句子用陈述语气。
eg. It looks as/though you are ill today. （陈述语气）
(2) 当说话人所陈述的是不真实的或极少可能发生或存在的情况时，从句用虚拟语气，从句的谓语动词用法如下：
与现在事实相反：一般过去时did/were
eg. He treats his students as if they were his own sons and daughters.
as if 引导的表语从句
教材 P50 It seemed as if the world were coming to an end! 仿佛世界末日即将来临！
as if 意为“仿佛，好像”，相当于 as though。as if 可置于look, seem, feel 等连系动词后引导表语从 句，也可以引导方式状语从句。
（1）as if 引导的从句常用虚拟语气，表示从句所述的情况不是真实的或极少有可能发生或存再。具体用法如下:
She talks as if she knew all about it.
Tom kept working as if nothing had happened.
(2)as if引导的从句所述的情况为客观事实或极有可能发生，则用陈述语气。
It looks as if we will be late. 我们似乎要迟到了。
(3)as if引导的从句有时可用省略形式，其结构为:as if+名词/不定式/分词/介词短语等。
He acts as if (he were) a fool. 他做事像个傻瓜。
Mike looked as if (he was) in search of something. 迈克看起来好像在寻找什么东西似的。
练习: 1)He talks as if he ________(know) everything in the world.
2)The clouds are gathering. It looks as if it _______(be) going to rain.
knew
as if+从句 一般过去时(与现在事实不符)
过去完成时(与过去事实不符)
would/ could/ might+动词原形(与将来事实不符)
is
3 “百分数/分数+of+名词或代词”做主语，谓语的单复数由of 后面的名词决定。
eg. Over 70 percent of the surface of the earth is covered with water.
40 percent of the workers are married women; the rest are single.
4 I was having breakfast with my three children when water started filling my home.(教材P54)
我正和三个孩子一起吃早餐，突然家里开始充满了水。
sb. was/were doing….when… 某人正在做……这时……

②sb.
/ sth. when...

③sb. sth. when...
某人正在做某事,这时(突然)……
had(just) done
was/were on the point of doing
was/were about to do
was/were doing
5. 不定式用主动形式表示被动意义
教材P50 Water, food, and electricity were hard to get. 没有水和食物，电也停了。
句式分析:主语(water, food, and electricity)是不定式(to get)的逻辑宾语,因此不定式后不能出现宾语。
（1）如果不定式中的动词为不及物动词，则其后要接相应的介词。
This kind of paper is not hard enough to write on.
（2常用的形容词有：easy, difficult, hard, interesting, pleasant,
comfortable, impossible, safe, fit, dangerous等
The book is difficult to understand. 这本书很难理解。
（3）变式： It+ be+ adj.+不定式（含宾语）
The man is easy to get along with. It is easy to get along with the man.
练习：The question is difficult for such a little boy _________(answer).
