情态动词表推测
· 用法
情态动词中的must, can, could, may, might都表推测。其中must的可能性最大，can/could次之，
may/might最小。具体用法如下：
1. must的用法
(1) 表示推测“可能性”时，意为“一定，准是”，语气较肯定，较有把握。如：
He must be an American.
他肯定是美国人。
(2) must表推测只能用于肯定句。如果要表示“一定不，肯定不”的意思时，应用can’t，若询
问某种可能
时，应用can。如：
He must know my address.
他肯定知道我的地址。
He can’t know my address.
他不可能知道我的地址。
Can he know my address?
他可能知道我的地址吗？
(3) must表示推测时，可以推测现在/正在发生的动作/过去发生的动作。如：
He must have a car now.
他现在肯定有车。
He must have finished the work.
他肯定已经完成工作了。
注：must表示推测时很少用于将来时。
(4) 在反义疑问句中，当附属部分含有表示推测意义的must时，疑问部分的助动词应与must
后面的动词
在非推测情况下的用法保持一致。如：
He must be a worker, isn’t he?
他肯定是工人，是吗？
It must have rained last night, didn’t it?
昨晚肯定下雨了，是吗？
You must have learned English for many years, haven’t you?你肯定已经学英语很多年了，是吗？
2. can & could
(1) can表示推测“可能性”时，往往用于否定句或疑问句中。Can’t意为“一定不”，语气很
肯定。Can在疑
问句中的意思是“会，可能”。如：
He can’t be at home.
他不可能在家。
(2) can/can’t后可接进行时/完成时，表示对现在发生的动作或过去发生的动作进行推测。如：
They can’t be reading in the library.
他们不可能在图书馆读书。
He can’t have gone to Shanghai for I saw him a minute ago.
他不可能去上海了，因为我一分钟前见他了。
It’s so late. Where can she have gone?
太晚了，她能去哪儿了呢？
(3) 在反意疑问句中，当陈述部分含有表示推测意义的can’t时，疑问部分的助动词应与can’t
后面的动词在
非推测情况下的用法 保持一致。如：
He can’t be a teacher, is he?
他肯定不是教师，是吗？
She can’t have finished her homework, has she?
她肯定没有完成作业，是吗？
(4) could可用于表示某事有可能发生可能是事实。如：
Don’t eat it. It could be poisonous.
别吃，可能有毒。
The plane could be delayed by fog.
飞机可能因为大雾晚点。
3. may & might
(1) may, might表示推测“可能性”时，意为“可能；也许”，语气没有must肯定。如：
He may/might be American.
他可能是美国人。
注：might不表示过去时态，只是语气上比may更委婉，表示的可能性更小。
(2) may, might表推测时，可以用于否定句，意为“可能不、也许不”，但不用于疑问句。如：
He may/might not be at home.
他也许不在家。
(3) may, might可以推测现在正在发生的动作或过去发生的动作。如：
He may/might be sleeping now.
他可能正在睡觉。

experienced hunger ( 饥 饿 ). These things have
influenced Mo Yan's later writings.

the new President of South Korea in December 9 2012.
She becomes the country's first female head of state
and her term will last five years from 2013. "I will
become a president who puts people's living before
anything else," she told the cheering people in central
Seoul as she accepted her win "I will keep my
promises.”

who was elected the 44th President of the United
States in 2008, has been elected again to a second
term, fighting against Republican challenger Mitt
Romney. Obama is a graduate of Columbia University

With the development of people’s living, more and more people concentrate on their health. The
death of 30% of people in the world is caused by heart disease (心脏病). In China, there are
thousands of people who die of heart disease every year. It’s necessary for people to know the
way to prevent (阻止) heart disease. Here’s some advice.
First, when you are under pressure, you should learn to get away from it. Too much pressure is
bad for heart. Don’t be angry, and keep a good mood. For example, laughing is important for
health. Second, eat more healthy foods such as corn, wheat, rice and potatoes. To keep a balanced
diet, eat more vegetables and fruit. Third, do exercise. You can get up early in the morning, go
outdoors, breathe (呼吸) the nice air and do exercise. Having exercise can make the heart
stronger. Then, don’t smoke. Smoking makes the heart jump faster and prevents more oxygen
(氧气) reaching the heart. Finally, you also have to have your heart checked once a year. The
doctor will give you good advice to keep a healthy heart. If you don’t feel well, you should go
to see the doctor at once.
These things sound easy, but not many people can really do them. In a word, if you want to
keep a healthy heart, please live a healthy lifestyle, eat healthily, take plenty of exercise, learn to
relax and never smoke.

Beautiful music, delicious dishes and a soft voice-over (旁白)—this is not A Bite of
China (《舌尖上的中国》), but a new video called A Bite of Jinan. Six teenagers from Jinan
made it.
Last month, they got a special homework—to introduce the traditional food of Jinan. The popular
show, A Bite of China, gave them the idea. Lü Kuangda decided to make a video like that. The
14-year-old boy had learnt about making films before. He called another five classmates and then
they had a group called Dage Film Team. They also asked adults for help—with Lü’s parents
joining the team. They spent about three weeks searching for information, shooting (拍摄) the
video and finishing the postproduction (后期制作).
Not all the restaurants believed in these students. They thought them troublemakers. Some even
drove them away. But they didn’t stop trying. Finally, their dream of making Jinan’s food
culture popular came true.
In the video, traditional delicious food shows up one by one. It makes people’s mouths water.
How long is the history of the food? What flavor (风味) do people in Jinan like best? It’s all
in this 11-minute video. Where can you watch it? Here’ s the link: http://v.qq.
