1. as if 引导的表语从句
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在。
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)

注意：be动词只能用were
(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.

在“主语+系动词+表语＋(for sb.) to do”结构中,表语常用的形容词有easy, hard, difficult, safe,interesting, heavy, light, pleasant, good, nice, comfortable ，dangerous, impossible 等。
此句型可转换成“It+be+adj. ＋(for sb.)+to do”结构。
① The book is very interesting to read (read).=It is very interesting to read the book.
②当不定式中的动词为不及物动词时，要在其后加上适当的介词。
The chair looks rather hard, but in fact, it is very comfortable to sit on.

3. 分数的表达及用法
Two thirds of the people who lived there were dead or injured.三分之二的
居民非死印伤。（本句是一个复合句,句中who lived there是定语从句,修饰先行
词the people在从句中做主语。）
(1)分数表达：①分子用基数词 在前，分母用序数词 在后；（母序子基） ②当分子大于1时，分母用复数形式。
如: 二分之一 三分之二
四分之一
