1 He is surprised to find his room ____(非常)clean.答案是thoroughly 请问对么 为什么2 Shirley____a book about China last year but I do not know whether she has finished it.A has written B wrote C had written D was writing 请问为什么
1. thoroughly, adv.彻底地；完全；非常 本来它就有非常的意思,另外它是副词,可以用来修饰后面的clean
2. was writing,表示过去某个时候正在做什么,原句的意思是说shirley去年在写一本关于中国的书,但不知道她现在有没有写完.在去年的时候,她正在写那本书,所以要用过去进行时,如果你用has written, 或者had written,首先它们是完成时,表示已经完成的动作,这个跟后面的意思相悖,因为后面说了还不知道她有没有写完,所以肯定是不能用完成时的,不管是过去完成时,还是现在完成时,而且时间是last year,所以A has written这个时间上也搞错了,然后就剩下B wrote了,它可以用在过去时,但原句中说的是去年那个时候,应该是正在写,如果是说去年她写了一本书的话,那就是写完了,就不会有后半句不知道她写完了没有了；汉语中的“着”,“了”,“过”大概就是这个意思
3. C cost 成本,代价 A value是价值,什么东西的价值或者做某件事有什么价值有什么意义,这里的价值都可以用value； B price,是价格,也就是某件东西的价钱 C cost 成本,代价,也就是做什么事情要花什么样的成本或者代价,必须投入的最低标准 D worth,价值,值得,有时候跟value可以通用,自己也可以做动词
我们一般说在哪里比如城市的生活成本比较高,这个地方用C cost,意思就是你在哪里生活每个月必须要花出的最少支出,这里不用price 价格,价格一般是具体一件东西的价钱,价格,比如一本书,一件衣服的价格等等,而cost 成本,代价,它可以包括很多这样的东西的价格,当然也包括其他方面比如时间成本等等
