Answer 1

D

試題分析：考查虛擬語氣。if虛擬條件句，對現(xiàn)在進(jìn)行虛擬，從句用過去時（be動詞用were），主句用would+動詞原形；對過去進(jìn)行虛擬，從句用過去完成時，主句用would/could have done；對將來進(jìn)行虛擬，從句用過去時或should/were to+動詞原形，主句用would+動詞原形。根據(jù)now可知，if從句是對過去進(jìn)行虛擬，從句用過去完成時，主句含有now，是對現(xiàn)在進(jìn)行虛擬，用would+動詞原形。這是錯綜虛擬條件句，要分別對主句、從句進(jìn)行判斷，分別使用對應(yīng)的時態(tài)。故選D。
