一、单项选择题
1.__ that the scientist will give us a talk next month?
A. Is true
B. Is it true
C. It's true
D. It's truly
题目解答
答案
B. Is it true
解析
本题考查主语从句的疑问句形式。关键点在于识别句型结构It is + 形容词 + that...的疑问形式。需注意:
- 形式主语it不可省略;
- 形容词需与系动词搭配(如true前不能用truly);
- 疑问句需将系动词提前。
句型结构分析
原句需表达“科学家下个月会给我们做报告是真的吗?”的疑问。正确句型为:
Is it true that...
其中:
- it是形式主语,无实际意义;
- true是形容词,与系动词is搭配;
- that引导真正主语从句。
选项辨析
- A. Is true:缺少形式主语it,结构不完整;
- B. Is it true:正确形式,符合疑问句结构;
- C. It's true:为陈述句,非疑问句;
- D. It's truly:truly是副词,不能修饰主语。
