I’m not sure if he ______ in this exam. But if he ______ harder, he will do better.
A.succeeds; worksB.will succeed; will work
C.will succeed; worksD.succeeds; will work
C

試題分析:句意:我不確定他是否能在這次考試中成功;但是如果他工作得更努力,他會(huì)做得更好。本句中兩個(gè)if 的意思并不一樣。第一個(gè)if 意為是否,引導(dǎo)賓語(yǔ)從句,根據(jù)句意可知,考試還沒(méi)進(jìn)行,故用一般將來(lái)時(shí);第二個(gè)if 意為如果,引導(dǎo)條件狀語(yǔ)從句,從句中用一般現(xiàn)在時(shí),主句用將來(lái)時(shí)。故選C。
