【解析】

10、B

因为先行词是the time，且在定语从句中作状语，所以用when引导。此题的先行词与定语从句被主句谓语分开了，要长于区分。

11、 B

先行词是Taiwan is a part of China整个主句，一般由as或which引导定语从句，但which引导的定语从句只能放在主句之后，另外，as有“正如”之意，而which没有，所以用as。顺便说说，原句改为：It is known to everybody that Taiwan is…= What is known to everybody is that Taiwan is…

12、A

两空都是考察定语从句，先行词分别是the day和Shen Zhou V was launched, the day在定语从句中作状语，用when引导;后句是非限制性定语从句，不能用that，要用which。
