Answer 1

问题一：提问的时态决定了该题的语境是一般过去时，选A，B错是因为它是过去进行时，我不可能在过去一直吹沙克斯管，C是现在完成时，D是现在完成进行时，都不对问题二：表示到双方说话时，已经决定或完成的动作，亦即这个人看起来已经决定了要去。应该用现在完成时，其他的时态都不正确问题三：translate,翻译，该句的translated表示被动，是指已经被翻译好了的公共通知。再考虑时态问题，最终选择D，而A表示即将被翻译的，B项进行时在此不合适，C应在中间加been。

Answer 2

1.I _____ the saxophone at regular intervals for many years when I was a child.A.played B.was playing C.has played D.has been playing时态题 when I was a child提示是过去时态 CD错误B是过去进行时 强调一直在做 而这里不需要 只要表明过去就可以了 2.--Do you really believe him?He is always changing his mind. --But this time,it seems that he _____ to go.A.will decide B.decides C.decided D.has decided你应该注意到上下文的时间范畴 do is 都是属于现在范畴 选项也应该是现在 AC排除其次 要表达的是 “他已经决定去了” 一定要完成时 所以 现在完成时 3.Mistakes in ______public notices can be seen here and there.A.being translated B.translating C.having translated D.translatedtranslated public notices translated是过去分词，做public notices定语 能理解吧in +名词 这里不是ing

Answer 3

1.不能看见句子中存在一段时间就选择现在完成时。这个句子后面有when I was a child，故为过去式态。2.根据语意，意思是但是这次他已经决定走了，别的选项放进去翻译也不合适。3.首先填空处是要填定语，另外是被动，
