b,Let me或 Let us表示听话人提出请求,问句用 will you或 won't you .
Let me have a rest ,will you (won't you )
c,其它的祈使句后可以加一个简短问句,使语气变得客气一些.
如:Have a rest ,will you
Stand up ,will (won't) you
特殊疑问句
以疑问词开头,对句中某一成分提问的句子叫特殊疑问句.常用的疑问词有:what who whose which when where how why等.
特殊疑问句有两种语序:
1.如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:疑问词(+主语)+谓语动词+其他成分?如:
who is singing in the room?
whose bike is broken?
2.如疑问词作其他成分,即对其他成分提问,其语序是:疑问词+一般疑问句语序?如:
what class are you in?
What does she look like?
Where are you from?
What time does he get up every morning?
How do you know?
注意:
1.回答特殊疑问句时,不能用yes / no,即问什么答什么,尤其是简略回答.如:
Who is from Canada?
Helen (is).
Where's the restaurant?
Near the station.
Why do you like koalas?
Because they are cute.
2.特殊疑问句一般读降调(↓).
