题目内容
20.---Is there any flight to New York?---I think there ______ be,for it is snowing so heavily.( )
A. | shouldn't | B. | mustn't | C. | can't | D. | needn't |
分析 ---有去纽约的航班吗?
---我觉得不可能有吧,因为外面正下大雪.
解答 答案:C
根据"for it is snowing so heavily"可知,非常有把握的猜测不可能,故用"can't"表示对否定动作肯定的猜测."shouldn't"意为"不应该","mustn't"意为"禁止,千万不要","needn't"意为"不必要".
点评 本题考查情态动词.考生需对情态动词用法了解,尤其表示猜测的时候,结合具体语境灵活使用.
