But attention please. The verbs “begin, continue, like, love, start” can be followed by either the Infinitive or the v. -ing form.

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. (Show the screen.) 1. We often hear her sing the folk song.= She is often heard to sing the folk song. 2. The girl wanted to go dancing, but her mother told her not to T: In the second sentence, “not” is put before the Infinitive. (Bb: not to do sth. ) To avoid repetition, the verb after the sign "to" is often omitted. But “to” can't be left out. This is done after such verbs as,, want, wish, like, love, hope, plan, try, hate etc. Now look at the examples on the screen. (责任编辑：admin) |
