Lesson 5 情态动词
考点一 表能力的情态动词
(1)表示 “ 能够 ”,can 用于一般现在时,could 用于一般过去时;
(2) be able to也表示能力,表示做事的能力时可与can通用,但be able to可用任何时态。
① She could / was able to draw when she was three.
② They will be able to finish the work soon.
考点二 表请求的情态动词
can (could)在疑问句中与第二人称连用时,表示征求对方意见或提出请求,表示委婉语气。
could 比 can 语气更加委婉客气,没有时间上的差别,回答只能用 can。
E.g. --- Could you lend me your pen? --- Yes, I can.
考点三 表许可的情态动词
may / might, can / could 表示许可常可互换,只是 might, could 语气比较委婉。
特别提醒:May I…? 否定回答用 No, you can ’ t. 或者 No, you mustn ’ t.
① --- May / Could I borrow your book?
--- Yes, you may / can.
② --- May I take the book out of the room?
--- No, you can ’ t. / No, you mustn ’ t.
考点四 表必须、必要的情态动词
must 和 have to 一般情况下可互换,但有以下区别:
(1)must 表示说话人的主观看法;have to 表客观需要。
(2)否定式 mustn ’ t 表示禁止,意为 “ 不准;不可以做 ”;而 don ’ t have to 意为 “ 不必 ”。
特别提醒:Must I…? 否定回答用:No, you needn ’ t. 或者 No, you don ’ t have to.
① You must / have to finish the work.
② You mustn ’ t copy others ’ homework.
③ --- Must I hand in my homework now?
--- No, you needn ’ t. / No, you don ’ t have to.
考点五 表推测的情态动词
(1)must 表示很有把握的推测,只用于肯定句,“ 肯定;必定 ”。
(2)could, may, might 表示把握不大的推测,用于肯定句,“ 可能;也许 ”。
(3)can ’ t 表示没有可能,用于否定句,“ 不可能 ”
① The photos must be Lu ’ s. Those are his parents. __________________
② The book may be his, but I ’ m not sure. ______________
③ The red bicycle can ’ t be Lucy ’ s. She has a blue bicycle. ______________
考点六 need的双重身份
(1)need 作情态动词时,多用于否定或疑问结构,一般不用于肯定句,表示 “ 必要 ”:
needn’t do sth. ;
(2)need 用作一般实义动词,根据需要作动词变形。
need sth.; need to do sth.; don ’ t need to do sth.
请判断下列的need在句子中作为情态动词还是实义动词。
① They needn ’ t go to work that day. __________________
② They didn ’ t need to work that day._________________
③ Do you need any help?_________________
④ I need to buy a pen._________________
