D. because
析：⑴ B ⑵ A 。 句 ⑴ 是 that 引导的定语从句，that 在从句中作 give 的宾语，因先行词 reason 之前有 best 修饰，故只能用 that 。句 ⑵ 是 why 引导的定语从句，相当于 for which 。
【指点迷津】
是定语从句还是状语从句 ？
你在做这样一道选择题时，该选哪个答案呢？
While reading the book , we\'d better make a mark we have any question .
A. at which B. at place where C. in which D. where
你或许要选择选项 A 或 C ，因为你认为此句含有一个介词 + which 引导的定语从句，然而句中的“ mark ”在逻辑意义上并非先行词，因为我们决不是在 mark 上有任何问题，所以 A 和 C 都不是正确选项。那么选择 B 正确吗?回答是否定的，虽然选项 B 中的“place ”可以充当 where 引导的定语从句的先行词，但单数可数名词被限制性定语从句表特指的概念，“ place ”前应有 冠词“ the ”。正确选项只能是D 了，即是由 where 引导的地点状语从句，此句中的 where 等于 at the place where 。再看下列句子。
I\'d like to take the pictures where stands the ancient tower . 我想在古塔那个地方照几张像。
Please put the chair where it was when the meeting is over . 请在会后把椅子放回原处。
Young people should go where they are badly needed . 青年人应该到最需要他们的地方去 。
以上三个句子均含有 where 引导的地点状语从句，句中的 where 可分别是由 in the place where , at the place where , to the place where 等替换。综上所述，引导地点状语从句的 where 通常可由适当的介词 + the place + 关系副词 where 替换，只要我们抓住这个关键就不难准确判断和使用 where 引导的定语从句和地点状语从句。最后再请试做下列选择题。
⒈ Many old people like to live there are many trees and flowers .
A. in which B. the place where C. in the place where D. which
⒉ This kind of bamboo grows best it is wet and warm .
A. which B. in which C. where D. the place in which
