It is a pity that you didn’t attend the lecture yesterday. 4.It + 不及物动词 ＋ that从句 It appears that… 似乎… It happens that …. 碰巧… It occurred to me that…我突然想起…… Eg. It occurred to me that I had left my bag in the bus. 由链接词链接的主语性从句 Whether he will come depends on the weather. What he said is reasonable. Where and when he was born remains a secret. whether he will come isn’t clear.(不能换成if) 改错：1.It is known that what one and one makes two is correct. 2.The Foreign Ministry said “This is our hope that the two sides will work towards peace .” 宾语从句中应注意的问题： （1）形式宾语it替代宾语从句 Sb+make/believe/think/find/ consider/feel…+it +adj/n.+that从句 Eg. I think it a pity that you didn’t pass the exam. I find it impossible that he should finish the work in two days. (2) 宾语从句的时态： 主句谓语动词：现在或将来时；从句谓语：任何所需要的时态。 主句谓语动词：过去时态；从句谓语动词：过去的某种时态 He told me Mary had been informed of the meeting. (3) that 引导一个宾从时可省，但引导两个或两个以上的宾从时，第一个可省，其余均不能省。 Eg .He said (that) he had been working here for ten years and that he wanted to go home. 表语从句 表语从句是名词性从句中最好辨认的从句，它只放在系动词的后面，对主语起解释说明的作用。其注意点如下： 表语从句的引导词的变化 增加了连接词：as if, as though, because 1. When the earthquake came, it was as if the world was at an end.
