1、如何正确判断强调句型英语强调句型的基本结构是“It+be+被强调成分+that (who)”。在该结构中，It wasthat (who)为强调句的结构词，原则上说，若将其去掉，句子意思依然清楚、结构依然完整。如：1.It was Jack who stole our money.是杰克偷了我们的钱。若去掉it waswho，即为：Jack stole our money.杰克偷了我们的钱。2.It was in May that you can see this kind of flower.你在五月可以看到这种花。若去掉it wasthat，即为：In May you can see th
2、is kind of flower.你在五月可以看到这种花。若去掉It wasthat (who)结构词，句子意思则不通、结构则不完整，那么就可能不是强调句。请看下面一题：It was ten oclock _ he came back.A.thatB.whenC.soD.which许多同学以为这是考查强调句型，从而误选答案A。而其实此题最佳答案是B。因为这不是一个强调句型，假若去掉结构词it wasthat，句子则成了Ten oclock he came back，此句要成立应在ten oclock前加适当介词。如：It was at ten oclock that he came back
3、.他是10点钟回来的。It was after ten oclock that he came back.他是在10点过后回来的。It was before ten oclock that he came back.他是在10点前回来的。It was ten oclock when he came back是一个包含有when引导的时间状语从句的复合句，全句意为“当他回来时，时间是10点钟”。英语强调句的特殊疑问句形式强调句型的陈述句形式和一般疑问句形式一般还好理解，但若以特殊疑问句形式出现，则很容易误解。比较：Mary bought a new car. (非强调句)It was Mary that bought a new car. (强调句型的陈述句形式)Was it Mary that bought a new car? (强调句型的一般疑问句形式)Who was it that bought a new car? (强调句型的特殊疑问句形式)特殊疑问句形式的强调句可视为对陈述句强调中的被强调成分提问得来，如对It was in 1985 that he was born这一句中的in 1985提问，即得到When was it that he was born?
