题目解答
答案
本题考察句式结构与语义匹配。A项“That is the case”无法引出后文；B项“There is the case”不符合习惯用法；D项“It is the case”需加“that”才能连接后文；C项“As is the case”可译为“正如……一样”，能自然引出“we have done a lot for the old teacher”。综合分析，C项最符合要求。
答案：C. As is the case
解析
本题考查固定句式结构的语义匹配能力，核心在于判断选项中不同短语的用法是否符合语境。关键点在于：
- "as is the case" 用于引出与前文相关的事实或情况，常用于让步或补充说明；
- "that is the case" 通常用于直接陈述事实，不引出后续内容；
- "there is the case" 属于存在句，但此处不符合逻辑；
- "it is the case" 需搭配 "that" 引导从句，否则结构不完整。
选项分析
A. That is the case
- 语义功能：直接陈述事实，如回答问题时确认情况（e.g., "That is the case."）。
- 问题：无法引出后续独立分句，逻辑不通。
B. There is the case
- 语义功能：存在句，强调存在具体事物（e.g., "There is the case on the table."）。
- 问题：后文为完整动作句，与存在句语境矛盾。
C. As is the case
- 语义功能：引出与前文相关的事实，表示“正如……的情况”（e.g., "He's busy, as is the case with most CEOs."）。
- 匹配性：后文 "we have done a lot..." 是对前文情况的具体说明，符合逻辑。
D. It is the case
- 语义功能：需搭配 "that" 引导从句（e.g., "It is the case that he will leave."）。
- 问题：后文无 "that"，结构不完整。
