| A. | didn't notice | B. | won't notice | C. | hadn't noticed | D. | don't notice |
分析 --Dave,看这个标志,在这里游泳危险.--哦,我没注意到,谢谢.
解答 答案:A 本题主要考查时态问题.根据it's dangerous to swim here.Look at the sign.推测可知下文是指过去没注意到,所以应该用一般过去时态,一般过去时态的构成:主语+谓语动词的过去式.本句中否定式为didn't+动词原形,所以答案是:didn't notice,故选:A.
点评 本题主要考查动词时态,判断动词的时态,要通过所给的时间状语或上下文等,去判断动词的时态.本题主要考查一般过去时态.
