1 Walter offered us a lift when he was leaving the office, but our work ___, we declined the offer.
A. was not finished
B. did not finish
C. has not been finished
D. had not been finished

答案是D自己也选对了，但说实话凭感觉选的- -``觉得had not been finished 应该是用于过去完成时态，不知道这样选对不对…

2 If I ___ home , I would have reminded him of the meeting.
A .was
B. were
C. had been
D. should be
答案是C 我选了两便才选对 先是D后是B 愁S我了。

3 Today the public ___about the way nature is being ruined.
A .is concerning
B. has been concerning
C. is being concerned
D. is becoming concerned
答案是D 我选的C 为嘛啊

4 I haven’t met him for ages, but his mother ___ him sometimes.
A. had still seen
B. still sees
C. has still seen
D. still saw
答案选B 我只认为除了D哪个都好像正确，指点指点```

A. should have
B. ought to have
C. could have

1） 过去完成时可以表示过去两个动作发生的先后顺序

2 If I ___ home , I would have reminded him of the meeting.
A .was
B. were
C. had been
D. should be
答案是C
我觉得是B

3 Today the public ___about the way nature is being ruined.

这题当中的today不是今天，而是进行时的另一种用法，表示最近一个阶段正在发生的事情或者状态。
concerned 是形容词，前面要和be动词连用

4 I haven’t met him for ages, but his mother ___ him sometimes.
把still去掉，再理解这个选项。
剩下的和频度副词sometimes连用的只能是一般现在时

5 I saw him going out on foot, but he ___ gone there by bus
A. should have
B. ought to have
C. could have
D. must have
答案是C 我开始选的D
这里需要表达的意思应该是“原本可以”吧，而不是推测判断

1 Walter offered us a lift when he was leaving the office, but our work ___, we declined the offer.
A. was not finished
B. did not finish
C. has not been finished
D. had not been finished

答案是D自己也选对了，但说实话凭感觉选的- -``觉得had not
