1. C. 因为of which引导定语从句，并在从句中作定语。of which the telephone number = whose telephone number。
2. D. 因为这是个非限制性定语从句，先行词是前面一句话的内容。
3. B. 因为表示“阶段、程度、地步”的the point在定语从句中作地点状语，所以用where引导定语从句。
4. B. 因为先行词是research centers并在定语从句中作状语，所以用where。
5. C. 因为当先行词是表示事物的all, little, few, much, anything, everything, nothing等时，多用that引导定语从句。
6. 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，要善于辨别。
7. 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…
8. A. 两空都是考查定语从句，先行词分别是the day和Shen Zhou V was launched, the
9. A. 因为替代不可数名词 (the bread) 只能用that，排除B和D;又因为先行词that (the bread)在定语从句中作buy的宾语，用which，所以选A。
10. D. 当定语从句的先行词前有such, so, as等词语时，由as引导，并且as在定语从句中作主语或宾语，as在此题中作dream of的宾语。注意：在表示“如此…以致…”的such /so…that…结构中，that不作任何句子成份。
