行为动词的一般现在时(2)
【语法感悟】
回顾课文语法,用括号内所给单词的适当形式填空。
1. It doesn't____(not) eat meat.
2. The tiger lives (live) in Asia.
3. — Does (do) it eat meat?
—No, it doesn't (not). It eats (eat) plants.
【语法精讲】
1. 动词第三人称单数变化规则:
(1)一般情况下,直接在词尾加“s”,如buy → buys。
(2)以s, x, ch, sh结尾的直接在词尾加“es”,如go→goes。
(3)以“辅音字母+y”结尾的,把y变为i再在词尾加“es”,如 cry→cries。
(4)特殊形式:have的第三人称单数形式为has。
【典例】
— B Lucy come from America?
—No. She ________ from England.
A. Does; does B. Does; comes
C. Is; doesn't D. Is; is
解析:题意:——露西来自美国吗?——不,她来自英国。表示“来自”的短语:come from或者be from,前者的一般疑问句用助动词do或does,因为主语是Lucy,所以用第三人称单数does;第二空因为主语是she,所以用comes。 故选B。
2. 基本句式:
(1)肯定句:主语+动词的第三人称单数形式+其他.
(2)否定句:主语+doesn't+动词原形+其他.
(3)一般疑问句:Does+主语+动词原形+其他?
肯定回答:Yes, 主语+does.
否定回答:No, 主语+does not.
(4)特殊疑问句:疑问词+does+主语+动词原形+其他?
【典例】— C he ________ a baseball?
—Yes, he ________.
A. Do; have; do B. Is; has; is
C. Does; have; does D. Does; has; has
解析:题意:——他有棒球吗?——是的,有。主语是he,谓语是have,变一般疑问句故用助动词does。故选C。
