Pleasegivemesomethingtodrink.不定式作定語時，要放在被修飾的詞語后面。不定式作定語時，與被修飾的詞語在邏輯上有主謂關(guān)系或動賓關(guān)系。3）Footballisasimplegametoplay.Becausetheroomwasverycrowded,Ineededatallbenchtostandon.Hewantedtofindanewhousetolivein.當不定式作定語，且與被修飾的詞語有邏輯上的動賓關(guān)系時，不定式動詞應該是及物動詞；如果不定式動詞為不及物動詞，則該動詞必須與介詞連用，組成及物動詞的短語。1）Hereturnedhometolearnhisdaughterhadjustslept.總結(jié)：不定式作結(jié)果狀語的用法2）IhurriedtoProfessorWang’shouseonlytofindhewasout.3）Shewassoangryastobeunabletospeak.

不定式作結(jié)果狀語常與learn,find,see,hear,make等動詞連用。only+不定式，常常表示出乎意料的結(jié)果。so/such…asto可作結(jié)果狀語。
