【文章內(nèi)容簡介】 re和 how。 1) that 引導(dǎo)的主語從句 ? That the match will be cancelled is now certain.(that引導(dǎo)主語從句時不能省略 ) That既可放在句首，也可放在句后。但為保持句子平衡，常用 it作形式主語，真正主語在句后。 用 it作形式主語已經(jīng)形成一些固定用法，如 ? It is a fact that… /It is a pity that… ? It is certain that / It is natural that ? It is said that / It is reported that… ? It seems that… / It follows that （由此可見） … 2) wh 詞引導(dǎo)的主語從句 ? What I have told you (All that I have told you) is convincing. ? When he will e is not clear. That 與 wh 詞引導(dǎo)主語從句的 區(qū)別： ? That只起引導(dǎo)作用，在句中不作任何成分； wh詞既起引導(dǎo)作用，又在從句中作一定成分。 ? 3） whether與 if 引導(dǎo)主語從句的 ? 區(qū)別： Whether we will go depends on the weather. ? 如在句首，只能用 whether. It is not important if / whether you win or lose. What is important is how you play the game. 2. 賓語從句 1） that 引導(dǎo)的賓語從句（ that?？墒÷裕? ? 我們相信他是誠實的 ? We believe ( that) he is honest. ? He told me that the road was closed. ? She suggested that he (should) do it at once( 虛擬） 2) 如果賓語從句后跟有補語，常用 it作形式賓語，而將從句放在賓補之后。 ? We consider it necessary that the instrument should be adjusted each time it is used. 3) wh 詞引導(dǎo)的賓語從句 ? She asked me where the post office was. ? You can’t imagine what awful weather we did have. ? * wh詞既起引導(dǎo)作用，又在賓語從句中作一定成分 ? Wh 賓語從句不能用倒裝語序。 介詞后可跟賓語從句 ? 4. No one was aware of where she had gone. ? He has not change at all except that he is no longer so talkative. 1. He asked me if / weather my brother was at home. 2. It is a question of weather we should go. ? 介詞后的賓語從句只能用 weather. ? 3. 表語從句 ? What surprised me was that he couldn’t speak English. ? That is why he was late for an hour. 表語從句中值得注意的兩個問題： ? His first question was ____ Tom had arrived yet. ? A) if B) whether ? Whether 可用來引導(dǎo)表語從句， if 不能。
