英语任务型阅读中对what问句有什么要求

如题所述

这是由连接代词或连接副词引导的宾语从句
我8年级 刚刚学了的
引出名词性从句的连词whether和if,在引出宾语从句时,用法和意义相同.但是只能引出宾语从句和不在句首的主语从句,而whether除了引出宾语从句外,还可引出主语从句、表语从句和同位语从句.
例如:
We don't know whether (if) it is right.
我们不知道它是否正确.
The question is whether she should do that.
问题在于她是否应该做那件事.
Whether it is true remains a question.
是真是假还是个问题.
试比较:
当if从句处在主句之后作“是否”讲时,引出的是宾语从句.
例如:
I don't know if it is true.
我不知道这事是否真实.
当if从句在主句之前作“如果”讲,则引出状语从句.
例如:
I shall go there if I have time.
如果我有时间,我将到那儿去.
when,where,why属于关系副词,都在其引导的定语从句中充当状语,其具体用法如下:
1.关系副词 when引导定语从句(包括限定性定语从句和非限定性定语从句)修饰表示时间的先行词,在定语从句中充当时间状语.例如:
I still remember the day when I first met Jennifer.我仍然记得第一次见到詹妮弗的那一天.
Next month,when you’ll spend your summer holidays in your hometown,is approaching.下个月即将来临,届时你们将在家乡度暑假.
2.关系副词where引导定语从句(包括限定性定语从句和非限定性定语从句)修饰表示地点的先行词,在定语从句中充当地点状语.例如:
This is the office where he worked.这就是他工作过的办公室.
She is going to live in Macao,where she has some close friends.她要到澳门去定居,在那里她有几个密友.
3.关系副词why引导限定性定语从句修饰先行词reason,在定语从句中充当原因状语.例如:
I don’t know the reason why he came so late.我不知道他来得那么晚的原因.
That is the reason why I don’t want to go.那就是我不想去的理由.
He didn’t tell me the reason why he was so upset.他没有告诉我他为什么那样心烦意乱.
注意:关系代词与关系副词之间并非毫无关联,两者之间存在密切的联系.在备考中尤其要注意以下几点:
1.很多情况下关系副词用“介词+which/whom”来代替,其中的介词由先行词或定语从句中谓语动词的形式来决定,例如:
The day when I met the famous pop star was the greatest day of my life.
= The day on which I met the famous pop star was the greatest day of my life.
见到这位著名歌星的那天是我一生中最重要的日子.
I shall never forget those years when I lived with her.
= I shall never forget those years during which I lived with her.
我将永远不会忘记我跟她生活的那些岁月.
This is a hall where the medical conference will be held.
= This is a hall in which the medical conference will be held.
这是礼堂,医学会议将在此召开.
2.并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句,若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、宾语等而不是状语时,需用which或that引导相应的定语从句.例如:
Do you still remember the days which/that we spent together in school?
你还记得我们一起在学校度过的那些日子吗?
先行词the days表时间,但是其定语从句的引导词在定语从句中作宾语而不是状语,因此不能用when而应该用which或that.
3.that有时可以代替定语从句中的关系副词when,where,why,且that常可以省略,例如:
This is the time(when/that)he arrived.这是他到达的时间.
