Unit 4
What would you do?
Section A

Grammar focus
1.虚拟语气:如果我们所说的不是事实,也不是 要求、命令、劝告等,而只是一种假设、愿望、 建议或是一种实现不了的空想就用虚拟语气。 注意: 条件句分两种, 真实条件句和虚拟条件 句。只有在虚拟(非真实)条件 句中, 才用虚拟语气, 而在真实条件句中, 要用 陈述语气。

请比较:
(1). If it is sunny tomorrow, we’ll go to

the zoo.
如果明天天气好, 我们将会去公园。 在这句话中, 明天天气好是完全 有可能实现的, 并非虚拟、幻想, 因此 是真实条件句。

(2). If I were you , I would go at once. (如果我是你的话, 我立刻就走。) 这句话是条件句 “如果我是你”, 但事实上, 我不可能成为你, 这只是假设的情况, 没有实 现的可能。当条件实现的可能性很小, 甚至可 以说没有时, 就需要用虚拟语气来表示, 动词 发生了变化。也就是说虚拟语气表示和现实 的事实相反时,从句用一般过去时, 主句用 “should/would/could/ might +动词原形” 。

?If I had time, I would go for a walk.

?If I were invited, I would go to the
dinner party. ?If I won a million dollars in the lottery, I would put it in the bank.

2. He doesn’t know if he should bring a present. 此处 if 表示“是否”, 引导宾语从句。 Should此处表示“应该”, 不是虚拟语气。 e. g. ①. I don’t know if I should go to the party. ②. If I have enough money, I will go to Hainan. Present 在这是“礼物”的意思。

3. If I were you, I’d wear a shirt and tie. if 引导的条件状语从句表示与现在事实相反 的虚拟语气时, be动词只能用were, 而不能用was。 e. g. If he were here, he would not agree with you. 4. I don’t have a present. What if everyone else

brings a present?
What if… “如果……怎么办? ”相当于 what

would happen if…
e. g. What shall I do if it snows?

Explanation
