1选择题
The teacher praised the student ______ essay was considered the best in the class.
- A. who
- B. whose
- C. which
- D. that
答案：B
解析：本题考查定语从句关系词的选择。先行词是"the student"，从句中缺少定语修饰"essay"，表示"学生的作文"，因此应用关系代词whose。易错点：误选which或that，忽略从句中名词essay需要定语修饰。
2选择题
It is required that every student ______ a mask when entering the library during the flu season.
- A. wears
- B. wear
- C. wore
- D. will wear
答案：B
解析：本题考查虚拟语气。在"It is required that..."结构中，that从句应用虚拟语气，谓语动词用"(should) + 动词原形"。易错点：误用一般现在时或过去时，未掌握该结构要求的虚拟语气。
3选择题
______ from the hilltop, the city looks like a beautiful garden.
- A. Seeing
- B. To see
- C. Seen
- D. Having seen
答案：C
解析：本题考查非谓语动词作状语。句子的主语是"the city"，与动词see之间是被动关系（城市被看），因此应用过去分词Seen。易错点：误用现在分词Seeing，忽略逻辑主语与动词的被动关系。
4填空题
The man ______ (talk) to our headmaster is from Beijing University. (用所给词的适当形式填空)
答案：talking
解析：本题考查非谓语动词作定语。分析句子结构，"The man"是主语，"is from..."是谓语，因此空白处应为非谓语动词作后置定语。动词talk与逻辑主语the man之间是主动关系，且动作正在进行，故用现在分词talking。易错点：误用过去分词talked，或误用定语从句结构。
5填空题
If he ______ (follow) the doctor's advice, he would have recovered sooner. (用所给词的适当形式填空)
答案：had followed
解析：本题考查虚拟语气在条件句中的应用。主句"he would have recovered sooner"表示对过去的虚拟，因此if从句应用过去完成时。易错点：误用一般过去时followed，未掌握与过去事实相反的虚拟语气结构。
6解答题
请将下列两个简单句合并为一个含有定语从句的复合句。
简单句：The girl is my cousin. She won the first prize in the speech contest.
答案：The girl who/that won the first prize in the speech contest is my cousin.
或：The girl who/that is my cousin won the first prize in the speech contest. (根据强调重点不同，两种合并方式均可)
解析：本题考查定语从句的构建。需要确定先行词（The girl）和关系代词（who/that），并将其中一个句子作为定语从句修饰先行词。易错点：关系词选择错误，或从句语序调整不当。
7解答题
请用非谓语动词改写下面句子，使其更简洁。
原句：Because he didn't know her address, he couldn't send her the letter.
答案：Not knowing her address, he couldn't send her the letter.
解析：本题考查用非谓语动词（现在分词短语）作原因状语。原句是because引导的原因状语从句，主语he与动词know是主动关系，且原因发生在主句动作之前，因此用现在分词的否定形式Not knowing。易错点：误用不定式或过去分词，或忽略否定形式。
8解答题
请分析并改正下列句子中的错误，并说明错误类型。
句子：I suggested that he went to see a doctor at once.
答案：改正后：I suggested that he (should) go to see a doctor at once.
错误类型：虚拟语气使用错误。在suggest, demand, order等动词后的宾语从句中，谓语动词应用"(should) + 动词原形"的虚拟语气形式。
解析：本题综合考查虚拟语气和句子改错。动词suggest后的宾语从句要求使用虚拟语气。易错点：误用一般过去时went，未掌握特定动词后接虚拟语气的规则。
