非謂語動詞是英語高考重要考點之一，而非謂語動詞作狀語更是重點中的難點。在平時的學(xué)習(xí)和操練中，非謂語動詞的錯誤率是比較高的。所以，同學(xué)們在學(xué)習(xí)中要理清思路，掌握要點，善于辨析，準(zhǔn)確判斷。請看以下例題：

例1 Though he was busy， he came_____me from time to time.

A. seeing B. to see

C. seen D. see

例2 The moment he knew the news， he came_____to me.

A. running B. to run

C. ran D. run

分析例1答案為B，例2答案為A。那么，謂語動詞同樣是came， 為何后面所跟的非謂語動詞卻不同呢？原因很簡單，例1中came后面所跟的非謂語動詞作目的狀語，故用動詞不定式to see; 而例2中came后面所帶的非謂語動詞雖然也作狀語，但表示行為方式，所以要用分詞表達(dá)。

動詞不定式和分詞都可以在句中作狀語，但意義有所區(qū)別。

動詞不定式作狀語時，通常表示目的或結(jié)果。表示目的時可用 in order to do， so as to do 或直接用 to do 表達(dá);表示結(jié)果時，常用too…to do， so…as to do/so as to do， enough to do， never to do， only to do等形式。其中，so as to 既可以表目的也可以表結(jié)果，但 so as to 不能用于句首。而分詞作狀語時則用來表示時間、原因、條件、讓步、行為方式或伴隨情況等。根據(jù)這一基本規(guī)則，我們就不難理解本文開頭兩道例題的解答了，語境不同，謂語動詞 come 之后的表達(dá)方式也就不同。
