A4 非谓语动词
热点4·1
①(2012·江苏卷)________an important decision more on emotion than on reason, you will regret it sooner or later.
A．Based B．Basing C．Base D．To base
答案 B [句意：凭借情感而不是理智作重要决定，你迟早会后悔的。本题中既无从属连词又无并列连词。由此可见设空处为非谓语动词作状语。C项是谓语动词形式，如选C项，需在“you will...前加并列连词and，构成“祈使句＋and＋陈述句”。D项表目的，不符合题意，所以排除。Basing an important decision...相当于If you base an important decision...。]
②(2012·江西卷)Having finished her project, she was invited by the school ________to the new students.
A．speaking B．having spoken
C．to speak D．to have spoken
答案 C [句意：完成了她的项目后，她应学校的邀请去给新生演讲。考查非谓语动词作主语补足语。根据“invite sb to do sth＝sb be invited to do sth邀请某人做某事”，排除A、B两项；D项不定式的完成时表示该动作先于谓语动词所表示的动作，不符合句意，应排除。]
