1.The boss has rejected the workers' demand that their wages (are raised)by 10 percent.
Key:are→be
Q:为什么要改成be阿,are哪里有错?是不是要被动呢?那改成were可以吗?

2.That type of automobile would you buy if you (are) free to choose among all the cars available today?
Key:are→were
Q:为什么要改过去式?哪体现过去了?难道是前面的would?询问情况不都是用would you like ……这样的句式么?难道would体现过去?
---------------------------------------------------------------
3.I know that even if the case was one (in which)it was impossible to anticipate the problem in advance,I could handle (whichever)I found.
Key:whichever→whatever
Q:怎么改我明白,可是前面括号中的in which引导的定语从句介词in应该还原到哪个位置阿?为什么要把in提前?这个介词前置我一直搞不清楚,请说详细点举些复杂点的例子,感激!

A:有一些动词,它们后面跟的宾语从句的谓语一定得用动词原形,不管是什么时态语态,像require(要求),suggest(v建议),demand(命令)都是这样的动词。更准确地说,这样的动词后面的宾语从句的谓语应该用should加动词原形,这个should可以省略,所以可以只用动词原形,这句话原应为...that their wages should be raised by 10 percent.
当这些动词用作名词的时候,它们引出的从句也遵循同样的原则...

A:这里其实是虚拟语气,也就是说后面的“如果今天你可以自由选择汽车”这个前提其实是不存在的,是说话人的一种假设,是虚拟的,虚拟语气一般都会用比主句时间上更前的谓语,也就是说,如果主句是现在时,虚拟句就会用过去时,如果主句用过去时,虚拟句就用过去完成时。严格的语法,在虚拟句中,即使是I,he作主语,谓语只要是be动词,都得用were,比如说:如果我是鸟,我就会飞。If I were a bird, I can fly.实际上我不是鸟,所以“如果我是鸟”这是虚拟的,用了过去时,而且be 动词用were,但其实现在英美人口语上也用was了。如果发后做题发现类似情况,没有were的话你就选 was,
