1.My mother often ask me _____ when Idon't feel well.
A.what the matter is （what's the matter？即怎么样了,有啥事么？而what's wrong表示哪里错了；what's the problem表示存在啥具体的问题或麻烦。此题是抽象提问,因此后两者不适用。另外此题双宾语结构里,疑问对象是句子,则句子要用陈述句。则转化为陈述形式——what the matter is。）
2. I never seem to lose any weight,_____ hard I try.
A.even though (even thougn表示尽管的意思；而as if是似乎的意思；no matter what若用no matter how 就正确了,因为hard是形容词必须用how来形容；ever since是一直以来的意思)
3.Is this the museum_____ you visited the other day ?
A. that (此题中museum是visit的直接宾格,而visit又是及物动词,所以用that指代,同时that还可表示强调；而where和 in which都表地点,在句中不合适； the one和the museum有重复之嫌,没有the museum再后面跟the one这种讲法。）
4. ______ the window, my hard was cut unexpectedly.
A. Cleaning (动名词表装态同时表原因，即表示因为擦窗,或擦窗的同时,手被意外地割破。)

1.正确答案是B.
宾语从句中需要用陈述语序,但是what is the matter 和what is wrong是两个特殊的句式,在从句中语序不变.C项语法正确,但是意思不合适,这里表示身体不舒服,而不是有什么难题.
2.没有正确选项,这里根据后面的hard i try来判断,应该填no matter how意思是“无论我多么努力”
3.选A.
做这样的疑问句的单选要还原成陈述句形式就容易了：
This is the museum____you visited the other day .
所以这个题就能看出定语从句缺少宾语,选关系代词that 就正确了.
4.选D.
如果选A或者C 从句的主语和主句的主语hand不一致是不可以省略的.所以,就要用状语从句形式.
比较：Cleaning the window, I had my hand cut.
这句话,主从句的主语一致,都是I 就完全正确了.
