7、1 .表示可能性的cant与 may not的区别。cant 常常表示“不可能”、“一定不”， maynot 表示“可能不、或许不”。很明显， cant 比 may not 语气强，把握性大。如：the manstandingover there _ be jack . hes gone to hongkong .a . mustn tb . can tc . won td . may not说话者既然知道“ hes gone to hong kong ”，那么对“ the man 不是jack”一定满有把握，故正确选项为 b 。2 .表示“能够”意义的can与 be able to的区别。凡

8、表示“经过努力、 设法做成某事”时不用can ，须用 be able to 。如：the firespread through the hotelvery quickly, but everyone _get out . ( nmet97 )a . had tob . wouldc . couldd . was able to句意为：大火弥漫整个旅馆，但人位学是设法逃了出来。故正确选项为d。3 .表示“不能”意义的cant与 mustnt的区别。cant 表示“不能”，是指无能力； mustnt 表示“不能”则指的是“禁止，不允许”。在口语里， cant 也可表示“禁止，不允许”，但语气不如

9、mustnt 强。如：( 1 )他年纪小，不能上学。【 正 】he is so youngthat he cant go to school .( 2 )里边正在开会，不能吵闹。【 正 】theres meeting inside . you mustnt make any noise .【 误 】there is a meeting inside . you cant make any noise .第3页共24页二、要注意几个使用的特定范围1 . 表示推测时， can 不能用在肯定句中 ( 但 could 能 ) ；may 和 might 不能用在疑问句中。如：( 1 ) peter _

10、come with us tonight , but he isnt very sureyet . ( met93 )a . mustb . mayc . cand . will句意为： peter有可能同我们一块儿来，但还不肯定。正确选项为b 。( 2 ) _ it be a sunny day tomorrow?a . canb . mayc . shalld . should句意为：明天可能是睛天吗?正确选项是 a 。2 . 作为情态动词， need 和 dare 不能用在肯定句中 ( 条件状语从句除外 ) 。肯定句中，须把它们用作实义动词，后接带 to 的不定式。如：【 误 】we n

11、eed hold a meeting to discuss the matter .【 正 】we need to hold a meeting to discuss the matter .【 正 】i f you need hold a meeting to discuss the matter , illgive you a help .3 . 在回答由 could 和 might 引起的表示请示的一般疑问句时，不能用 could 和 might ( 应分别用 can 和 may ) 回答。如： could i borrow your dictionary? yes , of cours

12、e you _ . ( met92 )a . mightb . willc . cand . could正确选项为 c 。三、要注意一些“形意不一致”的现象1 .过去式 could或 might后接动词原形可以表示对现在或将来(不是对过去 )的推测。如：i m afraid it _ snow tonight .第4页共24页a . canb . shouldc . mightd . must2 . may ( not )和 cant后接 的完成式，表示 去(不是 在或将来 )的推 。如： there were already five people in the car but they m

13、anaged to take me as well .it _ a comfortable journey .a . can t have beenb . couldnt bec . mustn t havebeend . shouldnt be四、要注意情 的常用形式的反常使用。1 . should 和 ought to 后接 原形，常表示“ ”；但也可用来表示推 ，意 “想必会”。如：( 1 ) it s nearlyseven oclock. jack _ be here ar any moment.( nmet95 )a . mustb . needc . shouldd . can句

14、意 ：“快七点 了，想必杰克随 会到的”。正确 c 。( 2 ) when can i come for the photos? i need them tomorrow afternoon . they _ be ready by 1200 . ( nmet98 )a . canb . shouldc . mightd . need句意 “ 我什么 候来取像片呢 ?我可是明天下午需要 些像片。”“ 像片想必会在 (明日中午 )十二点以前洗出的。 ”正确 b 。情 表示推 ， 气由 到弱的是：must ( 一定会) ought to / should(想必会 ) can / could (可能

15、 ) may / might (也 ，或 )。2 . could后接完成式常表示“( 去 )可能”，但也可用来表示 气，意 “ 去 )本来能 ，而 上却未”。如： we could have walked to the station ; it was so near . yes . a taxi _ at all necessary . ( nmet92 )a . wasnt b . hadnt been c . wouldnt be d . wont be第5页共24页该题虽是一道考查动词时态的考题， 但从“ wecould have walked to the station ”可知，实

16、际不是步行去火车站的。结合下句可知是坐了出租车去的，时间是过去，故正确答案是 a 。【指点迷津】look 短语动词归纳1 . look after照看，照顾，负责处理。i can look after myself .shes been looking after the luggage .2 . look at看 (问题 )，看待。that s the way i look at it .he looks at a question fromall sides .3 . look back ( on )回顾，回想 (过去 )。i like to look back on my high -
