强调句是小学阶段英语语法学习中的重点内容，也是对学生英语语法知识学习与应用能力要求比较高的内容。在历年的小升初英语考试中，经常会看到强调句的身影。那么对于同学们来说，如何才能更好地掌握强调句呢?下面沪江小编就围绕强调句结构为大家进行分析讲解。

　　一、常考的强调句结构是it 引导的句子;

　　It is 被强调部分+ that + 句子其他部分。

　　此结构强调的成分仅限于主语，宾语和状语。

　　It is from the sun that we get light and heat.

　　It was not until I had read your letter that I understood the true state of affairs.

　　二、典型例题

　　1) It was last night ___ I see the comet.

　　A. the time B. when C. that D. which

　　答案C. 强调句的结构是： It +be +强调部分 + that + 主谓句。 强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用 who ，其余用that。

　　原句： My father did the experiment in the lab yesterday evening.

　　强调主语： It was my father who did the experiment in the lab yesterday evening.

　　强调宾语： It was the experiment that my father did in the lab yesterday evening.

　　强调时间： It was yesterday evening that my father did the experiment in the lab.

　　强调地点： It was in the lab that my father did the experiment yesterday evening.

　　2)It is ten years ___ Miss Green returned to Canada.

　　A. that B. when C. since D. as

　　答案C. 考点是连词用法。 本题易误选为A. that. 其实本句不是强调句。若是，去掉It be that还应是一个完整的句子。而本句去掉 It is that ，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是强调句。

　　关于上述沪江小编为大家总结的关于强调句结构的相关内容，同学们是否有了深入的掌握呢?接下来我们需要做的就是将这些知识充分应用到自己日常的英语语法练习之中，通过经常性的练习来提升自己对于强调句的掌握效果和应用能力。
