Answer 1

第一题：作宾语补足语,可以使-ed或-ing,但是ing是主动,而ed是被动. 第二题：典型的现在完成时的题目,这里是指买了多久,但是buy是瞬间动词在完成是中转换成have表示状态. 第三题：刚刚还在,所以用过去时was,选A的话句意不同.后面是缩写,分开是it has gone,be gone是不见了的意思. 第四题：定语从句,A答案应该是which或者that,先行词book在从句中作bought的宾语. 第五题：信是被寄的,用被动语态,three days ago三天前过去了,用一般过去时,所以是was posted .yesterday昨天也过去了还是用过去时,到了不是被动的,不需要用被动语态. 三个词的区别：was用在一般现在时,has been用在现在完成时,had been用在过去完成时. 还算清楚吧~~(*^__^*) 嘻嘻……
