中考英语动词不定式

感官动词(feel, listen to, hear, see , watch, look at , notice) 后既可跟不带to的不定 式作宾补，也可跟v-ing作宾补.前者表 示动作的全部过程已结束；后者表示 动作正在进行。
e.g. I often hear her sing in the next room .
Ⅲ不定式放在及物动词后，用作宾语 e.g. They began to read and write. e.g. She forgot to close the door.
常用动词不定式作宾语的动词有：
want, plan, hope, learn, decide, would like, begin, start, try, need, forget, choose, agree, promise
4.Mrs Read w__is_h_e_s__h_e_r_s_o_n__to__l_e_a_rn__ (希望儿子 学) English well.
