Answer 1

我也是高一生，马上上高二了，看能不能帮到你（问题表述很多处错误……）
1.Mr Smith has 做house的后置定语，化简句子，就是（ ）the house broken into ，根据意思，联系时态应该是现在完成时，选C
2.我觉得A对。有连词and，说明put不是非谓语，连接的是一系列动词，所以都用过去时。
3.陈述过去发生的事件，没有隐含条件说明时态，用一般过去。
4.bring out 有使出现使明显的意思，其他几个意思都不对
5.B，被动。
6.选B，选A主句时态不对，C不对，不是强调，D不对，意思不对

Answer 3

1 现在完成时的应用，在过去某一点完成了动作
2 属于A，B and C ，及三个动作连续发生，C必定为非谓语 若是A and B,C 的形式，就全部都是谓语动词
3 动作在过去结束 我认为C也可以
4 理解的意思
5 notice sb doing 而且seat oneself 中采用ed
6 首先排除强调句式，其次until 时态不对 when 接段时间
