答案与简析：
1. B。当先行词被such修饰时，定语从句用as引导，即构成结构为"such+（a/an）＋形容词＋名词＋as"引导的定语从句，意为"......像......一样的"。整个句子意为：这些房屋以人们原来估计的那样低的价格出售。
2. A。由so interesting a story = such an interesting story和上面一题的解释便可得知答案。as在定语从句中作宾语。整句意为：我从未听说过像你告诉我那样有趣的故事。
3. A
4. C。当先行词被same修饰时，定语从句由that或as引导，但意思不同。用that引导定语从句指同一物，而用as引导定语从句指同类事物。
5. A。做此题的关键是要知道I think在定语从句中作插入语，做题时将其去掉便可容易得到答案。
6. B。Ａs在此引导非限制性定语从句，代表它所修饰的整个句子内容，并且它可放在所修饰句子的前、中或后面。其常见结构如：as you know, as is said above, as is often the case（情况经常是这样）等。如选Ａ，则需将逗号改为that；如选D，则需将逗号改为is that。
7. A。当先行词为the first time, the last time等时，定语从句的引导词用that而不用when。
8. A。当先行词为way时，定语从句的引导词用that或in which, 也可省略。
