				 Everyone in our class was  working hard and doing what we could         a good college.A.  enterB. to enterC.  enteringD. entered[解析]B.此句為省略句.即在 could 后省略了動詞 do.若把句子補完整應為Everyone in our  class was working hard and doing what we could do to enter a good college.即句中的不定式短語(to enter a good  college)是用作目的狀語的.而不是與情態(tài)動詞一起構成謂語.31He ran as fast as he could        to catch the early bus.A. to hope       B. hope        C. hoping       D. hoped[解析] C不是A.其中的現(xiàn)在分詞短語 hoping to catch  the early bus 用作伴隨狀語.			【查看更多】
