答案

1.know-knows,nobody要三单
2.began-begins,every evening是表示每个晚上,一般现在时,动词就用一般现在时就好,began是过去时,应改为三单
3.did-was,angry 是形容词,前面应该加be动词,时态是过去时,就用was啦
4.does-do,concerts 复数,do要复数形式
5.worked-has been working.Since 从句用过去时,主句用现在完成时或现在完成进行时,现在完成进行时,不仅表示动作从动作延续到现在,还表示现在动作仍在进行时中.
6.单词没打错?malied-mailed
7 ten 前面加个 for,表示火车已经在这十分钟了,要加介词for
8.have lost -lost ,去掉have,我刚丢的,不需要现在完成时,丢了就是丢了,过去的事情,用过去式就好了.
9.until- unless
10.are- were.yasterday昨天啦,注意时态
