初三年级英语作文：常用的十种句型

　　一、以形式主语it引导的句型。

　　句型1. It happened(chanced) that clause. = sb. happened /chanced sth. = sb. did sth. by chance. 如：

　　It happened that he was out when I got there. 当我到那儿时，碰巧他不在。

　　句型2、It seems that sb. do/ be doing/ have done/ had done= Sb. seems to do/ be doing/ have done/ had done 如：(还有动词appear可这样使用)

　　It seemed that he had been to Beijing before.好象你以去过北京。

　　二、定语从句：

　　句型1、由as引导的非限定性的定语从句。如：

　　As we have known, he is a most good student.众所周知，他是个很好的学生。

　　句型2、由which引导的非限定性的定语从句。如：

　　He is a professor, which I have been looking forward to becoming.

　　他是个教授，那是我一直盼望的职业。(因为先行词professor是表示职业的名词，因此引导词用which，而不用who。(注意：关于which和as之间的比较请看语法的定语从句部分。)

　　三、让步状语从句

　　句型1、No matter what / which / who / where / when /

　　whose 从句， 主句。注意从句中的时态一般情况用一般现在时态。如：

　　No matter what you do, you must do it well.

　　四、条件状语从句

p>　　As we have known, he is a most good student.众所周
