Unit 2 Sprting events
通过对情态动词的介绍来帮助学生学习掌握情态动词。
情态动词没有人称和数的变化，有词义，但是不完整，不能单独做谓语，必须和不带t的动词不定式连用。
make requests
make suggestins
make ffers
give advice
Mdal verbs: general intrductin
(1) He can run the 100m sprint in 11 secnds.(2) Can this little girl read befre she ges t the primary schl?
can表示可能性时，指的是理论上的可能，它通常不用来表示某事实际发生的可能性或真实性。如： Accidents can happen. Anybdy can make mistakes．
can / be able t
在过去时态的肯定句中需要某种条件或努力做成某事，我们要用was／were able t而不能用culd。如： It was a hliday and the children were able t g t the seaside． The girl wrked hard s she was able t pass the final test．I’m srry I haven’t been able t play tennis with yu recently.
ught t/shuld
ught t与shuld意思接近，大多数情况下二者可以互换，但是shuld谈的是自己的主观看法, 用于各种人称。 ught t则更多反映客观情况，在谈到法律、义务和规定时使用。如： We shuld／ught t help each ther and learn frm each ther in ur wrk．Yu shuldn’t spend s much time playing. She is yur mther, s yu ught t supprt her． Ought he t g? Yes, I think he ught (t).
have t / must
must与have t都可以表示“必须”的意思，但要注意以下两点区别。 1) must只有现在时，而have t有现在时、过去时和将来时。如： We must wrk hard, r we’ll fail in the examinatin． Tw years ag, the pr girl had t leave schl fr lack f mney．
2) must表示主观看法，have t则侧重于客观需要。如： We must be strict with urselves in everything． In cities with many cars, sme peple have t wear masks．
