哦,我问的不是if引导的虚拟条件句,是虚拟语气中的be-型虚拟。虚拟语气不是分were型和be型什么的么? 展开

你问的不对吧,虚拟语气又称“非真实条件句” 即对不可能发生的事情假设。 例如 if I were you。 事实是 你不可能成为他,所以这个被称为虚拟句。相反If it is fine tomorrow,we will go toXX.. 这个事条件句 ,因为它是对可能发生的事情进行假设。( 明天天气好不好 , 就目前这个状况是不能肯定说 的。) 虚拟条件句 一般的呢 分从句 和主句 , 主句的现在时态,一般将来时态都可以采用 sould \would (could\might也行,不过通常不是用这个) + 动词原形。 从句的一般时 用动词(过去式) 注意 不是过去分词哦。 如果是BE 采用were
instance:
If I knew his telephone number,I would tell you.
从句将来时可采用 三种方式
if+主语+were to do
if+主语+should+do
if+主语+did(动词过去式)/were
If she were to be here next Monday,I would tell her about the accident.
从句是过去式 用had done , 主句用would\should have done
If he had taken my advice,he would not have made such a mistake。
还要注意 就是当 其句中动词 或者是形容词 含有, 建议、命令、要求、目的 都使用虚拟句(你肯定见过这类句子,只不过一般省略了should\would)
一想要(desire) 一宁愿(prefer) 一坚持(insist)二命令(order , command) 三建议(advise , suggest , propose/recommend) 四要求(demand , require , request , ask)
They recommend that this tax(should) be abolished
注意 当 suggest,insist。这俩个次用于表示 坚持,暗示的建议,
不可以使用虚拟语气
he insist that he is innocent.
另外 还要注意 一个倒装结构, 那就是如果if 引导的虚拟句中 有 were should had 可以省略,并将动词提前。
were i scientist, I could help him。
