小升初英语语法强调句知识点：It is...that…句式通常不能强调哪些成分
　　有这样一道考题：
　　It was a teacher that she __________.
　　A. was B. seemed C. looked D. married
　　此题应选D。从句意上看似乎4个选项都行，其实这里只能填D。因为填A，B，C 中的任意一个选 项，都会导致句中的 a teacher成为表语，然而按照强调句句法规则，It is...that这一强调句型是不能 强调表语的。一般说来，以下成分不能用于强调句中的被强调部分：
　　1. 表语：
　　她很美。
　　正：She is beautiful.
　　误：It is beautiful she is.
　　他是医生。
　　正：He is a doctor.
　　误：It is a doctor that he is.
　　但是宾语补足语却可以用作被强调部分：
　　他们选他担任主席。
　　正：They elected him chairman.
　　正：It was chairman that they elected him.
　　2. since 和 as 引导的原因状语从句(但 because 从句却可以)：
　　他不能来是因为他病了。
　　正：It is because he is ill that he can’t come.
　　误：It is since[as] he’s ill that he can’t come.
　　3. although 引导的让步状语从句：
　　虽然累了，但他还是去了。
　　正：He went although he was tired.
　　误：It was although he was tired that he went.
