  • The farmer uses wood to build a house in which to store grains.

    in 介词前置,which是关系代词,指代house,在用木头建造的房子里面储存(store)粮食,所以用in.

    Now we can fly to Tokyo.There was a time when we had to take a boat.

    when是关系副词,引导定语从句表示时间.当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时,它只能作定语从句的时间状语,放在定语从句句首.这句话的意思是,我们现在可以乘飞机去东京,而原来我们只能坐船去.

    The size of the audience,as we had expected,was well over twenty thousand

    as 引导非限制性定语从句,可放在主句之前,或者主句之后,甚至可以切割一个主句;which引导的非限制性定语从句只能放在主句之后.另外,as有“正如……,正像……”的意思,这句话的意思是说观众的人数正像我们所预期的一样,超过了两万.
