too much: 中心词在much, 意为 “太多,过分”, 在句中作定语,修辞不可数名词,也可用作状语, 修辞动词, 还可用作主语、表语等.
例如:
Sorry that I’ve put you too much trouble.

much too: 中心词在too, 意思是 “极其,非常”, 修辞形容词或副词,表示程度.

这道题对我来说太难了.
His condition is much too bad, and needs a further examination.

although 和 though：“虽然，尽管”的意思。都可用作连词引导让步状语从句，两者可互换。
例如：
They are generous although/ though they are poor.
他们尽管穷，却十分慷慨。
though 引导让步状语从句时和as一样，表语可以提前；此外，though 还可以用作副词。

他虽然工作很辛苦，但却一直是入不敷出。
It’s a hard work; I enjoy it, though.
这是件苦差，不过我倒很乐意干。（though 用作副词）。
even though：和even if同义， “尽管，即使,纵然”，用作连词引导让步状语从句，语气比though, although更强。
例如：
She won’t leave the television set, even though/ even if her husband is waiting for his supper.
即使她丈夫等着她吃晚饭，她也不愿意离开电视机。
as though：和as if 同义，“好像，仿佛”，用作连词，引导表语从句和方式状语从句。
例如：
He sounds as though/ as if he’s got s sore throat.
他的声音听起来好像是喉咙痛。

他张开嘴，好像要说什么。
三、重点句型
1．Now that we are developing new technology at such a high pace, the true challenge is to find new ways of using it. 既然我们正高速地发展新技术, 真正的挑战在于寻找新的使用途径.

如:

2．Maybe it is time for the rest of society to accept me as I am and get used to the fact that while I may not be able to walk, there are many other great things I can do. 或许到了社会上的其他人承认我的时候了, 到了他们接受这样一事实的时候: 虽然我不会走路, 但仍有很多事情我可以做.
