其实你的问题都是和“事实相反的假设语气”有关 1 和现在事实相反的假设语气 If I were you, I would commit suicide. If I had one million dollars, I would donate it to the charity. 注意这里的be动词一定用were即使是单数 If he were you, he would slam me in the face. 简单说就是if後面用过去式,主要子句用would + v 是说如果我是你 我会自杀 是说如果我现在有钱 我就捐给慈善机构 2 和过去事实相反的假设语气 If I had been rick, I would have donated it to the charity. If I had been you, I would have committed suicide. 是说我过去如果有钱我就会捐给慈善机构 是说如果我以前是你的话 我就会自杀 简单说就是if後面用过去完成式,主要子句用would have + Ｖpp 注意had可以提到前面 Had I been rick, I would have donated it to the charity. 3 和未来事实相反的假设语气 If the sun were to rise in the west, I would marry you. 如果太阳打西边出来我就嫁给你 If後面用were to, 主要子句用would + v 4 表极不可能发生的假设语气 If he shoud come, let me know. 万一他来了告诉我 should可以提到前面 Should he come, let me know. 3 ※ 引述《isaac028 (da)》之铭言： : 不好意思,小弟才疏学浅，想请教各位大大几题英文文法试题(出处:王怡华-文法练习1000 : 题) : 1.------out of season, I would have ordered some from the fruit stand. : (A)If oranges would have been : (B)If oranges have not been : (C)Had oranges not been : (D)Should oranges not have been : 答案:(C),不明白为何选它?另外，假设题目改为I wouldn't have ordered....是否可选 : 择(A)? 这题主要子句用would have + pp 表示是和过去事实相反的假设语气 if 要用过去完成式 If the oranges had not been out of season, 但had提到前面 Had the oranges not been out of season : 2.I wish I were as smart as you-------. : (A)have been (B)had been (C)are (D)were 这是和现在相反的假设语气 you are表示是事实 所以用现在式 : 答案:(C),为何不是选(D)? : 3.I would rather she------tomorrow than today. : (A)come (B)came (C)should come (D)has come : 答案:(B),为何不是选(A)? would rather 原V than 原V? 这题他今天已来所以应该用过去式 : 4.I would buy that book but I-------enough money. : (A)do not have (B)did not have (C)will not have (D)had not had 这题可以把I would buy当作主要子句 他用would表示和现在相反的假设语气 所以but用现在式 : 答案:(A),不明白为何选它? : 5.Mary might have come to school in time for Professor Smith's lecture-------. : (A)if she got up earlier : (B)unless she had got up earlier : (C)but she got up rather late : (D)but she had gotten up so late 这题如果用假设语气 Mary might have come to shcool in time for xxx if she had gotten up earlier. 和过去事实相反的假设语气 but後面要加过去式 : 答案:(C),不明白为何选它? 由文意来看，如果她早起就可能参加演讲,是这样子的吗? : 6.We would have arrived sooner except we-----a flat tire. : (A)had (B)would have (C)has not (D)has : 答案:(A),不明白为何选它? 和过去相反的假设语气 except是对等连接 类似but後面用过去式 如果是假设语气 会用 We would have arrived sooner if we had not had a flat tire. But we had a flat tire. : 7.--------their assistance, he would have to lead a very miserable life; : he might even starve to death. : (A)With (B)But for (C)Without for (D)If not 这题he would是和现在相反的假设语气 But for表示要不是因为有人家的协助他就要过的很惨 with表示有了人家的协助才过得很惨 不和语义 without for两个介系辞不通 if not没有动词 : 答案:(B),不明白为何选它? : 8."He would go to see you.""-------he did not some?" : (A)What if (B)Where if (C)What come (D)Why whether : 答案:(A),不明白为何选它? 这题表示他应该会来看你,我方反问他“如果他没来呢” what if表示如果他没来怎麽办 假设语气是相当烦又难的 这些题目有蛮刁钻 如果有问题再讨论 : 感谢各位!! --
