情态动词表推测的用法小结
(一)情态动词表推测的三种句式
1.在肯定句中一般用must (一定),may(可能),might /can, could(也许,或许)。
(1)He must/may/might know the answer to this question?
他一定/可能/也许知道这个问题的答案。
(2)It is cold in the room. They must have turned off the heating.
屋里很冷,他们肯定把暖气关了。
2. 否定句中用can’t / couldn’t(不可能), may not/might not (可能不)。
(1)It can’t/couldn’t be the headmaster. He has gone to America. 这不可能是校长,他去美国了。
(2)He may not/might not know the scientist. 他也许不认识那位科学家。
3. 疑问句中用can/could (能……?)。
(1)Could he have finished the task? 他可能把任务完成了吗?
(2)Can he be at home now? 他现在能在家吗?
注:以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式,而表示语气较为委婉或可能性较小。
(二)情态动词表推测的三种时态
1. 对将来情况的推测,用“情态动词 + 动词原形”。
(1)She must / may / might / could arrive before 5. 5: 00 前她一定/可能/也许到。
(2)She must/may/might/could walk miles and miles among the hills without meeting anyone.
她一定/可能/也许会在山里一连走好几英里而遇不到一个人。
2. 对现在或一般情况的推测,用“情态动词 + be”,“情态动词 +be doing”或 “情态动词 + 动词原形”。
(1)He must / may / might / could be listening to the radio now. 他一定/可能/也许正在听收音机。
(2)He can’t ( couldn’t ) / may ( might ) not be at home at this time. 这个时候他不可能/可能不在家。
(3)Mr. Bush is on time for everything .How can ( could ) he be late for the opening ceremony ?
布什先生一向准时,这次开幕式他怎么可能迟到呢?
3.对过去情况的推测,用“情态动词 + have +过去分词”。
(1)It must / may / might / could have rained last night .The ground is wet. 地湿了,昨晚肯定/可能/也许下雨了。
(2)The door was locked. He can ( could ) not / may ( might ) not have been at home . 门锁着,他不可能/可能不在家。
(3)Can / Could he have gotten the book? 难道他找到书了吗?
注:情态动词 should /ought to表推测时,意为“想必会,理应……”但与“have +过去 分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。
例如:
(4)It’s seven o’clock. Jack should/ought to be here at any moment.
现在七点钟了,杰克理应随时到达。(推测)
(5)She should / ought to have attended your birthday party, but she had to look after her mother in hospital. (虚拟)
她本该出席你的生日晚会的,可是她得在医院照顾她妈妈。
(6)Tom should not /ought not to have told me your secret, but he meant no harm. (虚拟)
汤姆本不该告诉我你的秘密,可是他并无恶意。
考点名称:特殊疑问句
- 特殊疑问句:
以特殊疑问词开头,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。
特殊疑问句的基本结构是“疑问词+一般疑问句”。
其回答应当是具体的。特殊疑问句句末一般用降调。
例如:How do I get there?
Why not?
What about the sports news? - 常用疑问词可先分为3种:
疑问代词:
what(什么)
who(谁,作主语)
which(哪个,在一定范围内选择)
whose(谁的,指附属关系)
whom(谁,作宾语)
疑问副词:
when(何时,询问时间)
where(何地,询问地点)
why(为什么,询问原因)
how(如何,询问手段,方式,工具以及程度)
疑问形容词:
what(which,whose)+名词
例词:
what time(什么时候) what colour(什么颜色)... ...
how much(多少) how long(多长)... - 特殊疑问句的特点:
一、 特殊的疑问词:
特殊疑问句要由疑问代词或疑问副词开头,询问的内容不同, 使用的疑问词也不同。
我们学过的疑问词有what(询问事物), how much(询问价格), what time (询问时间,尤其是点钟), what kind of(询问种类), why(询问原因),who(询问人), where(询问地点) 等等。如:
—What is this? 这是什么?
—It's a key. 这是一把钥匙。
—How much is it? 这个多少钱?
—It's twenty dollars. 二十美元。
—What kind of movies do you like? 你喜欢哪一类型的电影?
—I like action movies. 我喜欢动作片。
二、特殊的语序:
特殊疑问句由疑问词开头,其构成是“疑问词 + 一般疑问句”。如:
What time is it? 现在几点钟?
Who is your teacher? 谁是你的老师?
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:
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:
特殊疑问词+一般疑问句(特殊疑问词+be/助动词/情态动词+主语+谓语)
What does she like?
What class are you in﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know﹖
三、特殊的答语:
特殊疑问句不能用yes, no来回答,而应根据它所询问的内容直接做出回答才行。如:
— What time is it, please? 请问几点了?
— It's 7:30. 七点半了。
— Where are they? 他们在哪儿?
—They're in the playground. 他们在操场上。
—What's your favorite subject? 你最喜爱的科目是什么?
—English. 英语。
四、 特殊的语调:
一般情况下,特殊疑问句要用降调(↘)来读。如:
Who's ↘that?
How old is↘Jack?
