1分赛车个位必中技巧1分赛车个位必中技巧,高中英语语法教案 Teaching Goals: 1. To enable Ss to know about the way to express possibility and improbability. 2. To enable Ss to master the usage of “may”, “might”, and “likely”. 3. To help Ss learn how to use modal verbs “may” and “might” to express conjecture. Teaching Procedures: Step 1. Revision Check the answers to the Vocabulary exercises in the Workbook. Step 2. Function 1. Ask Ss to do Activity 1 on page 54 and call back the answers. Then give them the correct answers. 2. Ask Ss to identify the creatures in the pictures in Activity 4 on page 55, by using “may” or “might”. Arouse their interest in talking about possibility. 3. Ask Ss to do Activity 2 on page 54 individually. Then check their answers. Step 3. Grammar 1. Leading-in Ask Ss to work in groups and discuss the question in Activity 1 of Grammar on page 57. Then give them the right answer. 2. Explanation Explain how to use modal verbs to talk about something which happened in the past— perhaps. (1) 对过去的事情进行猜测,但把握较小时,肯定形式一般用 may have done,否定形式 一般用 may not have done。如: He may have gone back home, because he didn’t say he would take part in her birthday party. He may not have paid for the bill, because he had lost his job. (2) 对过去的事情进行猜测,但把握更小时,肯定形式一般用 might have done,否定形 式用 might not have done。如: They helped send her bat to the hospital; otherwise, she thought, the baby might have died. She might not have left home when I got to school. (3) 对过去的事情进行猜测,并且可能性较大时,肯定形式一般用 must have done,否 定形式一般用 can’t have done。如: Your score is the highest; you must have studied very hard. You can’t have seen her in her office last Friday; she’s been out of town for two weeks. 3. Practice Ask Ss to do Activity 2 on page 57. Then call back the answers and correct them. 4. Supplements Explain how to use modal verbs to talk about something which happened at present—perhaps. 用来表猜测的情态动词有:must, can, may 等,但它们所表示可能性是不同的。1分赛车个位必中技巧 (1) 对现在的事情进行猜测,并且可能性较大时,肯定形式一般用 must 加动词原形, 此时,must 不再表示“必须” ,而是表示“肯定” ;否定形式一般用 can’t 加动词原形,此时, can 不再表示“能够” ,而是表示“肯定不……” 。1分赛车个位必中技巧如: I saw him go out just now. He can’t be in his own room. It must be Linda in the classroom, because she is on duty today. (2) 对现在的事情进行猜测,但把握较小时,肯定形式一般用 may 加动词原形,此时, may 不再表示“可以” ,而是表示“可能” ;否定形式一般用 may not 加动词原形。如: He may tell the truth to his father. She may not angry because she is good-tempered. (3) 对现在的事情进行猜测,但把握更小时,肯定形式一般用 might 加动词原形;否定 形式一般用 might not 加动词原形。如: She might not be angry because she usually is very patient. He might be at home now, but I’m not sure. (4) 情态动词+动词现在进行时,表示对现在或将来正在进行的情况进行推测。如: At this moment, our teacher must be correcting our exam papers. Doctor Wang isn’t here. He might be giving a lecture in the hall. (5) 情态动词+动词的现在完成进行时,表示对过去正在发生事情的推测。如: Your mother must have been looking for you. The light was on the whole night. He may have been doing his homework all the time. 5.
