不定式省to的口诀.pptVIP

巧记不定式省TO 的口诀 By Ms.Wang 我们知道不定式可作主语，宾语，表语，定语，状语，也可作宾语补足语。 作宾语补足语时，有时可加上不定式符号to, 有时可省略to. 那么什么情况下可加to ,什么情况下不加to ？ 在下列词语后的不定式作并宾补要加to: tell sb. to do sth., ask sb. to do sth. want sb. to do sth, order sb. to do sth. teach sb. to do sth, would like sb. to do sth. allow sb. to do sth, expect sb. to do sth. encourage sb to do sth, advise sb to do sth. wait for sb to do sth, remind sb to do sth. 但在有些词后面的不定式符号to可省 这些词是：let(让），feel(觉得），notice(注意），help(帮助,既可加，也可省），两使（make, have), 两听（listen to, hear),四看（look at ,see, watch, observe). 为了方便学生记忆，在教学中我把这些词编成口诀： 不定式省to有习惯，只有动词11个半； 让，觉得，注意和帮助，两使两听加四看。 运用与练习 1：用不定式填空 ⑴.The boss made the boy -------(work) all day. ⑵.I heard a girl -------(sing) in the next door. ⑶.He said he didn’t see anyone-------(come ) in the shop. ⑷.Does your mother allow you --------(go) out on Sunday? ⑸. The teacher reminded her --------(not make) the same mistakes. ⑹. On my way to school, I often hear some birds -------(sing) in the trees. ⑺. Who saw him ------(break) the window? ⑻. Our teacher often encourages us ------- ( work) hard at our lessons. 2. 改错： ⑴. He noticed a man to get into the building just now. ⑵. Nobody knows where find him as if he had lost in the world. ⑶. We were told pay more attention to the government’s policy. ⑷. Something must be done protecting the environment. ⑸.Let them to do the project together. 以上我们练习的都是主动语态中的运用。那么，我们要记住：这些省to的动词在被动语态中必须加上to 。e.g. 1. The boy was made to work for eight hours every day. 运用与练习 1. In the past the children were made ------ 15 hours a day. 2. Mr. Green asked them ------(stop) talking so that everyone could hear him. 3. You’d better -------(not break) the rules. 4. He was made ------(go) to bed early as he was a bit sick. 5. The teacher asked the homework -------(do) at once. 6. The young man was noticed-----(drive) the car in a hurry. * * *
