Answer 1

1. This kind of computers _A_______ on the market only in July, but they _______ popular recently.
A. appeared; have become B. had appeared; become
C. appear; became D.appeared; are becoming
这种电脑在七月出现 说明已经出现了 并且在七月 过去的时间 用一般过去时态
但是最近变得流行了 这个动作一直延续到现在 还可能延续到将来 所以用现在完成时态
2. My mother ____C____ to play the piano when she was only 4.
A. advised B. is advised C. was advised D. was advising
首先排除AB 因为从句是用的过去时态
我的母亲在她四岁的时候被建议弹钢琴 被建议 不是主动去建议别人 所以被被动
希望能够帮到楼主

Answer 2

1.A 有时间状语 in july 表明过去，所以用一般过去时，后面popular recently 是一种有影响的结果
2.C mother小时候被建议所以用过去时且被动语态

Answer 3

1.选A 句末recently 直接判断第二空应该用现在完成时
2. 当她四岁时她就被建议学弹琴, 根据时态一致 排除B 这里没有显示进行概念 排除D 剧中分析得出My mother 是动作的承受者 所以用被动 选C
