47. (2.0分) ( ) the little girl knows so many things.A. He is surprised thatB. He was surprised thatC. To his surprise,D. What surprises him is that

本题主要考查“surprised”与“surprise”的用法区别以及句式选择。关键点在于：

1. “surprised”是形容词，需跟在主语后构成短语（如主语+be surprised that...），且主语需明确；
2. “surprise”是名词，可构成介词短语（如To one's surprise），直接修饰后文主句，无需主语；
3. 选项D的结构虽然正确，但句式复杂，不符合题目对简洁性的要求。

选项分析

A. He is surprised that

• 错误原因：引入主语“he”，与后文主语“the little girl”矛盾，且句式冗余。

B. He was surprised that

• 错误原因：同A，且时态为过去式，与原句的现在时不符。

C. To his surprise

• 正确性：介词短语直接修饰主句，无需主语，符合“令某人惊讶的是”这一语境。

D. What surprises him is that

• 错误原因：句式冗长（主系表结构+从句），与题目简洁性要求不符。
