答案：
1. C) 【句意】 虽然只懂一点西班牙语，但他还是参加了这个课程的学习。
【难点】 know是静态动词，不能用于进行时；选knows从句中又缺少主语。knowledge作“知识”讲时是不可数名词，但作“了解”讲时，前面可加“a”，常用于词组haver a knowledge of中，所以选C)。
2. B) 【句意】 你本应该给詹姆斯写信，然而，你没写。
【难点】 ought to have written是虚拟语气，与本句句意相符。
3. B) 【句意】 约瑟夫幸运地逃了性命；他险些没从房间里逃出来。
【难点】 to have escaped 是不定式的完成式，表示过去的某一动作业已完成。
4. A) 【句意】 黄油面包受西方人青睐。
【难点】 bread and butter 是西方人吃的一种食品，虽然有三个字，表达的却是一个东西，并且是不可数名词，作单数。
5. A) 【句意】 我家的后花园有一片草坪，夏天坐在上面会令你心旷神怡。
【难点】 which引出非限制性定语从句，在句中作主语，且和sit on 构成动宾关系。类似的句子有：This room is comfortable to live in 这句中live in 和this room构成动宾关系。
