1<Whoever> does it makes no difference.为什么不能用No mater who ?
2I am sorry I haven't done as much as I could.是固定用法么
3Take care <that> your classmates should not misunderstood your ideas.为什么不可以用so that ?
4I would not have made such pregress if<it had been for>his help.为什么这样用?
5He was surprised <when >he found himeself the only boy there.用as soon as 为什么错呢
6Ships carry lifeboats so that the crew can escape <if >the ship sinks.为什么不能用in case
7Patient as he was 这是一个什么用法``
谢谢啊```感激```知道这个途径真好```

其区别只是no matter...从句只能用作状语从句，而whatever...从句除了可作状语从句一 ，还可用作名词性从句在句中充当主语或宾语，有时甚至是宾语补足语。例如：
No matter which /whichever you say, I won't believe you. 我不管你说什么，我都不会相信你说的话。
No matter which /whichever of three sisters you choose to marry, you will have a good wife. 无论你选择三姐妹中的哪一位结婚，你都将得到一位贤淑的妻子。
此外，no matter一般不单独使用，可以用在It's no matter (It makes no matter)+从句这种句型中表示“无关紧要”，如：
It makes no matter /It's no a matter whether you get there early or late. 你到达那里早或晚都无关紧要。
It makes no matter to him that brother lost all his money. 弟弟赔（丢）光了钱，对他无关紧要。

2.这句话没有什么固定用法吧.里面的as...as倒是有,意为"和……一样"，

3.so that 是前后都要连接句子的,你那里take care只是个动词
that在这里是引导状语从句

4.应该是"progress"
句子意思为"如果没有他的帮助,我不可能取得这样的进步."
所以就这样用了,也可以写"if<it had been for>his help,I would not have made such pregress if"这里if引导的都是状语从句

5.as soon as 是连词噢~不能引导状语从句吧
在表示时间状语的时候一般都是用副词,when while...

6.in case
