(write them on the blackboard.)
t: very good. there are some verbs followed by either the infinitive or the v.-ing form. do you know what they are.'?
ss: like, begin, continue, forget, regret, remember, start, stop, try'”
t: right. but attention please. the verbs “begin, continue, like, love, start” can be followed by either the infinitive or the v. -ing form. (bb: begin, continue, like, love, start)and they have the same meaning. while the verbs “for get, regret, remember, stop, try” can also be followed by the infinitive or the v. -ing form. (bb~ forget, regret, remember, stop, try) there are some differences between them. now look at the examples on the screen.

1. i like playing football, but i don’t like to play it now.
2. i remember seeing her once somewhere.
3. i must remember to take my notebooks with me.
t: from the first sentence, we know the v.-ing form is an action in general while the infinitive is an action on a certain occasion. in the second and the third sentences, the v.-ing form is used for a past event while the infinitive is used for a future action. are you clear?
ss.. yes.
t: please translate the sentences into chinese. one student , one sentence.
s4:我喜歡踢足球,但現在不愿意。
s5:我記得在哪里見過她。
s6:我必須記住帶上筆記本。
t: good. when the infinitive is used as object and is followed by object complement, we often use this structure. s. + v. + it + adj. in. + infinitive. (write it on the blackboard.)now please make some sentences with the structure.
s7: i thought it unnecessary to argue with him about it.
s8: he considers it his duty to help others.
t: very good. which verbs do you think can be followed by the infinitive as object complement? ss: advise, allow, ask, want, wish, order, tell, have, let, make, feel, hear, watch, see…
t: yes. some verbs, like “advise, allow, ask, want, wish…” must be followed by the infinitive with “to”, while the verbs “ have, let, make, feel, hear, watch, see…” must be followed by the infinitive without "to". (bb: advise, allow, ask, want, wish, order,… have, let, make, feel, hear, watch…) but you mustn't forget “to” in the passive voice. look at the examples on the screen.
