主从连词 that , whether , if
连接代词 who , whom , whose , what , where , which
连接副词 when , where , why , how
倒装句
Never , Scarcely , hardly , rarely , little , nowhere , no sooner ~ than , not only , in no case , in no way , on no accoune , at no time , under no circumstances (这些词或词组放在句首作壮语时)
There be 句型和大多数的疑问句都是倒装句
Here , there , then , thus 等副词放在句首时,谓语动词为come , be , exist , follow 等不及物动词时,句子一般都为全部倒装 Here is a book for you . Here comes the bus .
句首为 so , nor , neither 等副词时、表明前句说明的情况也适用于本句时 ,句子为倒装
Richard can speak Japanese . So can his sister
在虚拟语气中,非真实条件从句中的连词省略时,句子为倒装。这时,倒装到主语前的助动次 had ,should 和动词were 。 Had I left a little earlier , I would have missed the train
so / nor / neither + 系动词/ 助动词 / 情态动词 + 主语
表示前句中谓语所说明的情况也同样适用于后句中的主语,用到装。
He doesn’t like music . Nor / Neither do I .
在Hardly ~~ when 和 No sooner ~~ than 以及 Not until 的句型中,由于否定词或否定词组放在句首,主句部分中的主、谓要到装―――助动词 + 主语 + 动词原形
No sooner had he got well than he left the hospital .
直接引语和间接引语
John said , “ I ‘m going to London with my father .”转自环 球 网 校edu24ol.com
John said that he was going to London with his father .
一般疑问句变成以if (whether ) 引导的宾语从句
He said , “Have you all understood this passage ?”
He asked the class if they had all understood that passage 。
祈使句变为动词不定式, 作ask , tell 等动词的宾语补足语。表示命令时常用 tell , order 等;表示请求时常用ask , beg 等动词,原句中的don’t 应变为 not 。
The manager said to the clerk , “Be polite to all the clients .”
The manager told the clerk to be polite to all the clients .
如主句谓语动词为各种现在时或一般将来时,间接引语中的动词仍保持直接引语的原来时态
He says , “ I am very busy reading the book .”
He says that he is very busy reading the book .
如主句谓语动词为过去时,间接引语中的动词应发生如下变化:
一般现在时―――一般过去时
现在进行时―――过去进行时
一般将来时―――过去将来时
现在完成时―――过去完成时
一般过去时―――过去完成时 过去完成时不变
直接引语转换成间接引语时,代词一般相应变化如下:
this -- that last week ? the week before
therse ? those three days ago ? three days before
now ? then tomorrow ? the next day
today ? that day next week ? the (next ) following week
this week ? that week here -- there
yesterday ? the day before come ? go
