望采纳，谢谢！
6 have learnt 时间词by the end of所以用完成时havedone
7 is chatting 与前句照应，前句用isn't，表示现在进行时。
8 are talking 关键词是listen提醒你用进行时
9 happened 过去的时间in1976所以用一般过去时
10 was stolen 时间词last week所以用过去时，又由于是被动，所以用steal的过去分词
11 was interviewing 延续性动词interview所以用进行时。just now一般用于过去时，意为“刚才”；
I saw him just now.我刚才见过他。如果用于现在时，表示“now”的强调，意为“现在，此刻”；
I am busy just now。我此刻很忙。
12 is leaving 时间词in ten minutes 表示十分钟之后，所以用将来时，但是leave等词进行时就表将来。不用will leave
13 have learnt 时间词for 3 years 暗示你用完成时。
14 joined 同第9题的道理，in 1997表示过去的时间，用过去时
15 was picking 表示看到他们的瞬间，她们正在摘苹果，表示进行时的瞬间。
16 costs
17 had begun 电影已经开始了，过去完成时
18 goes 时间词every day所以用一般现在时
19 seems you are right，暗示你主从句时态一致。如果是you were right，填seemed
20 are playing同第8题，look提醒你是现在进行时。
