　　热点八：非谓语动词

　　[热点透视] 非谓语动词作状语、定语和补语

　　[难点剖析] ①非谓语动词作状语：注意前后逻辑主语一致；结合省略对考生进行综合考查；区别祈使句式和并列结构，关注标点符号，在解题时尤为关键。

　　②非谓语动词作定语：不定式作定语表动作尚未发生，与所修饰名词构成动宾关系。若不定式逻辑主语同时也为句子主语，用主动表被动，反之用被动(如：I’m leaving on business. Do you have anything to be taken there?)，另还需注意不及物动词加介词；现在分词作定语表动作正在进行或习惯性经常性动作；过去分词作定语表动作完成，与所修饰名词构成动宾关系。

　　③非谓语动词作补语：能后跟非谓语动词作宾补的动词数量有限，格外注意使役动词和感官动词；为增加试题的干扰性，将宾语和补语分离改作定语从句的先行词(如：The managers discussed the plan that they would like to see carried out the next year.)或将作宾补改作主补(如：The missing boys were last seen playing near the river.)；注意“with+ n.\pron.+补语”结构的用法。

　　④动词不定式作状语、定语时，注意避开定向思维的干扰。

　　例 Which do you enjoy to kill your spare time—watching TV or playing football?

　　⑤疑问词+to do 的用法。

　　例 It is said that in Australia there is more land than the government knows what to do with it.
