谢谢大家的，各人有各人的选择，我不晓得谁是谁非了。do门or 和 jiajia的似乎有道理，可是也不一样。看得头疼~~

Answer 1

C。还原为正常语序就很好理解了。This museum is the one （that）you visited the other day.
the one 代替museum，先行词作宾语，可省略。
B。see sb. doing sth. 看见某人正在做某事， 这里是被动句式。were也没有错，后面的just now说明是过去时态。
A.see sb. doing sth. 看见部分过程。

Answer 2

C. 这里的one是代词，代替museum.
B.怀疑是不是把'were'打错了哈。。。
A.see sb do sth是从头至尾；see sb doing sth是看到的时候，正在进行着。

Answer 3

A B C

Answer 4

1C 排除法 因为visit是及物动词故排除B 对于A也能排除，因为如选A则为定语从句，但本句子缺少先行词，除非在museum前面加the构成先行词能选B，故本题选C
2c be seen to do sth 是固定搭配
3c see的用法 see sb do sth( 表示看见事情发生的全过程或经常做的事）和see sb doing （看见正在做某事，强调正在进行）本题很明显表示看见他经常做的事，故用see sb do sth
希望我的答案对你有帮助，还有我认为学习英语就要多记，尤其是固定搭配和习惯句法一定要烂熟于心，加油！

Answer 5

我的感觉1提选A。后两题选B。此答案只供你参考。你也可以借鉴别人的答案。

应为are playing
A see sb do sth 看见某人做了某事

Answer 7

C This museum is the one you visited the other day定语从句
B时间状态just now限定动作状态为进行时状态
