课件26张PPT。 Grammar——— The Noun Clauses名词性从句?　　在句子中起名词作用的句子叫名词从句 (Noun Clauses）。 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句(Subject Clause)、宾语从句(Object Clause)、表语从句(Predicative Clause) 和同位语从句(Appositive ClauseWho will win the match is still unknown. I want to know what he has told you. The fact is that we have lost the game. The news that we won the game is exciting. 主语从句宾语从句表语从句同位语从句 Subject Clause (主语从句) Object Clause (宾语从句) Noun clause Predicative Clause (表语从句) ?????????????????????????????主语从句 一个句子在复合句中充当主语叫主语从句。 e.g. That the earth is round is true . Whether she will come or not is still a question . What you are doing seems very difficult . When they will start has not been decided yet . 引导主语从句的连词是不能省略的。 That the earth is round is true That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：It is true that the earth is round.It's a pity that you should have to leave.　你非走不可真是件憾事。Attention2.表示“是否”意义时，一般用whether 而不用 if引导主语从句， Whether she will come or not is still a question . 但如果有形式主语 it引导时，既可用 whether，也可用 if。 e.g. It is still a question if she will come or not . 3.有时可用形式主语it 代替主语从句： e.g. It is still a question whether she will come or not . It has not been decided yet when they will start . 　用it作形式主语的that-从句有以下四种不同的搭配关系： It + be +形容词+ that-从句It is necessary that…　　　 有必要……It is important that…　　　 重要的是……It is obvious that…　　　　 很明显…… b. It + be + -ed 分词+ that-从句It is believed that…　　　　　人们相信……It is known to all that…　　　从所周知……It has been decided that…　　 已决定…… 　c. It + be +名词+ that-从句It is common knowledge that ………是常识It is a surprise that…令人惊奇的是……It is a fact that…　　事实是…… d. It +不及物动词+ that-分句It appears that…　　　　似乎……It happens that…　　　　碰巧……It occurred to me that … 我突然想起…… 1. ____ you don’t like him is none of my business. A. What B. Who C. That D.
