情态动词表示推测的意义和用法
情态动词（Modal verb）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法，多用来表达能力、意愿、义务、许可，还可以表示推测。
表示推测的情态动词主要有 must, can, could, may, might, can’t等。

情态动词表示推测的意义和用法
1. must表示说话人对事物的推测可能性的程度非常大，意为“一定；准是”，表示肯定推测，只能用于肯定句。如果要表示“一定不”，应该用can’t。如果询问可能性时，应该用can。
如：她没接电话。她肯定是出去了。
She isn’t answering the phone. She must be out.
他肯定知道答案。
He must know the answers.
mustn’t 在英语中不能用于表示推测，但可以表示“禁止，不允许”之意。
2.may, might表示推测“可能性”时，是把握性不大的推测，意思是“可能”，“也许”。might不表示过去时态，might语气更委婉，可能性更小。may, might表推测时，可用于否定句，但不用于疑问句。
如：他可能不在家，不过我也不确定。
He may/might not be at home, but I’m not sure.
迈克为什么没来上课？他可能生病了。

五、阅读理解
“Save the whales！” That's what the picture on Jake Smith's bedroom wall said. Jake liked having a picture that said something important; that showed he cared. He just never expected to get a chance to save a real whale, one right in his own neighbourhood.
It was a Saturday morning when the newspaper first reported the whales' coming. A group of the animals were swimming close to the beach in Jake's hometown. All the local people rushed out to the beach to see them. They were expecting a beautiful show, better than a movie, but nothing they'd have to do anything about.
Then one whale swam in their direction, directly towards land. It came in with the waves, and when the waves receded，it stayed. Its huge body rested on the sand. Suddenly, Jake and his family and all the others were no longer sightseers. They had to become rescuers. A few people ran towards the animal. They pushed and tried to force the whale back into the water, but it was no use.
An animal rescue service team soon arrived in a truck with heavy lifting machinery, to help move the animal. Jake and his family couldn't do much on the beach, so they went back to their house and made sandwiches and hot tea for the rescuers. At least, Jake thought, they could help in some way.
Back at the beach, they offered the food to the rescuers and were happy to see that it was needed. It was getting dark. Some people lined up their cars along the beach and shined the headlights on the sand. The rescuers would not give up. After trying many times they were finally able to lift the whale into the water. Everyone cheered when it headed out to sea. It swam out about a mile and then disappeared for a moment under the sea. Then, in what looked like a jump of joy, it rose high above the water—a thank you to those who had worked so hard to save its life.
( )26. What does the picture on Jake's wall tell us about him？
A.He lived near the ocean. B.He cared about the environment.
C.He worked as an animal rescuer. D.He thought whales were the most beautiful animals.
( )27. Why did the local people go down to the beach that morning？
A.To swim with the whales. B.To help rescue the whales.
C.To see the whales swimming. D.To watch a movie about whales.
( )28. The underlined word “receded” in Paragraph 3 means ______.
A.didn't move B．went back out C.washed over D．got up
( )29. How did Jake and his family help save the whale？
A.By calling the rescue service. B.By asking their neighbors for help.
C.By giving the rescuers food and drink. D.By controlling the people on the beach.
( )30. In what order did the events of the whale rescue take place？
a. The whale disappeared under the sea. b.People turned on the lights of their cars.
c.Rescuers lifted the whale into the water. d.Animal rescue service brought its truck.
