It 做形式主语和形式宾语的句型.pdf

常见的It 句型（包括it 做形式主语和形式宾语） 1.It is/was + 被强调部分 + that/who ... 该句型是强调句型。被强调部分可以是主语，宾 语，表语或状语。强调的主语如果是人，that 可以由 who 换用。如果把这种句型结构 划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 一般陈述句：Tom bought a book in this bookshop yesterday. It is Tom who/that bought a book in this bookshop yesterday. 强调主语 It is a book that Tom bought in this bookshop yesterday. 强调宾语 It is in this bookshop that Tom bought a book yesterday. 强调地点状语 It is yesterday that Tom bought a book in this bookshop. 强调时间状语 2. It is not until + 被强调部分 + that ... 该句型也是强调句型。主要用于强凋时间状语， 译成汉语 “直到……才……”，可以说是 not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. 强调句 = Not until she took off her dark glasses did I realize she was a famous film star. 倒装句 = I didnt realize she was a famous film star until she took off her dark glasses. 一般句式 3. It is+形容词（clear /obvious/true/possible/certain …）+ that 从句 该句型中it 是形式 主语，真正的主语是 that 引导的主语从句，常译为 “清楚（显然，真的，肯定……）” 是主语从句最常见的一种结构。 It is very clear that hes round and tall like a tree. = That hes round and tall like a tree is very clear. 4. It is+形容词（important /necessary/ right/strange/natural... ）+that 从句(should) do 该 句型和上一个同属一个句型。由于主句中的形容词不同，that 后的从句中要用虚拟语气 （should + 动词原形），should 可以省去。 It is necessary that we (should)learn a foreign language. 注意句型3和4从句中动词的形式 5. It is+过去分词( said, reported, learned…) +that 从句 该句型中的it 仍是形式主语， 真正主语是 that 引导的主语从句。该结构常译为“ 据说（据报道，据悉……）”。 It is said that he is studying abroad. = He is said to be studying abroad. 6. It is+ 过 去分词 (suggested ,ordered, required, commanded, advised, proposed, recommended ) +that 从句 (should) do 该句型和上一个同属一个句型。主句中的过去分 词是表示请求，建议，命令等词时，that 后的从句要用虚拟语气（should + 动词原形）， should 可以省略。常译为“ 据建议；有人命令……）”。 It is suggested that you should get up early in the morning. 注意句型5和6
