答案：

1. C) 【句意】 雖然只懂一點西班牙語，但他還是參加了這個課程的學習。

【難點】know是靜態(tài)動詞，不能用于進行時；選knows從句中又缺少主語。knowledge作“知識”講時是不可數名詞，但作“了解”講時，前面可加“a”，常用于詞組haver a knowledge of中，所以選C)。

2. B) 【句意】 你本應該給詹姆斯寫信，然而，你沒寫。

【難點】ought to have written是虛擬語氣，與本句句意相符。

3. B) 【句意】 約瑟夫幸運地逃了性命；他險些沒從房間里逃出來。

【難點】to have escaped 是不定式的完成式，表示過去的某一動作業(yè)已完成。

4. A) 【句意】 黃油面包受西方人青睞。

【難點】bread and butter 是西方人吃的一種食品，雖然有三個字，表達的卻是一個東西，并且是不可數名詞，作單數。

5. A) 【句意】 我家的后花園有一片草坪，夏天坐在上面會令你心曠神怡。

【難點】which引出非限制性定語從句，在句中作主語，且和sit on 構成動賓關系。類似的句子有：This room is comfortable to live in 這句中l(wèi)ive in 和this room構成動賓關系。
