题目内容
1.Sandy listens carefully,but she ________ anything.( )| A. | listened to | B. | didn't listen to | ||
| C. | hear | D. | doesn't hear |
分析 桑迪仔细听,但她什么也没听到.
解答 答案:D.考查否定句.句意"桑迪仔细听,但她什么也没听到.".listen to表示听的动作,hear表示听的结果.结合语境but表示转折,应该是"没听到任何声音",用否定形式,及表示听的结果的hear.she是第三人称单数,含有实义动词,一般现在时态,因此用助动词doesn't.实义动词用原形hear.答案是D.其它不正确.
点评 考查否定句.通常是在be动词,情态动词后加not.一般现在时态,主语不是第三人称单数用don't,主语是第三人称单数用doesn't.一般过去时态用didn't.还有其它用法需要牢记.
