题目内容
17.Mr.Smith won't go to work if he this afternoon.( )| A. | won't feel good | B. | will feel good | ||
| C. | doesn't feel well | D. | feels well |
分析 史米斯先生如果今天下午不舒服,他将不去上班了.
解答 答案:C.考查否定句.句意"史米斯先生如果今天下午不舒服,他将不去上班了.".if引导的条件状语从句时态上遵循主将从现,因此从句用一般现在时态,A,B不正确.结合语境"他不将去上班",可知应该用否定形式,表示感觉不舒服,因此D不正确.答案是C.主语是第三人称单数,含有实义动词,一般现在时态,变否定句在实义动词前用doesn't,实义动词用原形feel.
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.
