10、t_up. 他决定放弃学英语。He_decided_to_give_up_learning_English.give up意为“放弃”，是由动词副词构成的动词短语，其宾语可以为名词或代词。当宾语为代词时必须放到动词和副词之间；give up 后面还可以跟动名词，它的意思为“放弃做某事”。2动词不定式的用法 戒烟是很正确的。Its_right_to_give_up_smoking. 他想走。He_wants_to_go. 她不让我走。She_doesnt_allow_me_to_go. 我有许多作业要做。I_have_much_homework_to_do. 我来这看你。I_come_here_
11、to_see_you. 我的工作是照顾好你。My_job_is_to_look_after_you_well.不定式由“to 动词原形”构成，其否定形式是“not_to 动词原形”。不定式可以带宾语或状语构成不定式短语，没有人称和数的变化，但有时态和语态的变化。不定式可作主语、宾语、宾语补足语、表语、状语和定语，但不能单独作谓语。不定式短语作主语时，往往放在谓语之后，用it作形式宾语；不定式短语作宾语时，如果还带有宾语补足语，往往把不定式宾语放在宾语补足语之后，而用it作形式宾语。有些动词后只能用动词不定式作宾语，如：decide，plan，expect，hope，wish，pretend，promise，refuse，afford，agree，ask等。3Why not _ a new hairstyle？Maybe you like it.Atry onBtry outCtry to Dhave a try答案选择B，根据句意“为什么不尝试一个新发型呢？也许你会喜欢它”，可知答案选择B，try out 意为“尝试，试验”。try on 意为“试穿”。请学生们做前面课时训练部分。
