Answer 1

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

Answer 3

1 know----knows nobody的谓语使用单三形式
2 began---begins at every evening时间状语提示使用一般现在时，主语是he使用单三
3 did-----was angry是形容词，不用did,用be
4 does....give-----has....given表示已经做过某事，对现在产生了影响
5worked--------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 mailed------had mailed，对方收到信是过去时，你在过去的过去寄出信，所以用过去完成时

7 ten-----for ten 现在完成时中需要一个介词"for"来引时间段,同时"since"引的是时间点
8 have----/ 我刚刚掉的
9 stops----has stoped “车停下”对“你下车”有影响关系，意为车“已经”停下，你下车
这都时完成时的问题
10 are----were 后面的yesterday提示使用过去时
