初一下册英语知识要点
现在进行时态:
概念:表示现在(说话瞬间)正在进行或发生的动作,也可以表示目前一段时间内或现阶段正在进行的活动。
结构:由be动词(am, is, are) + 动词ing构成,其中be动词要与主语保持性数一致。 Mary is flying a kite in the park. 玛丽正在公园里放风筝。
--What are you doing now? 你现在在干什么?
--I’m reading English. 我正在读英语。
Are they drawing the pictures now? 他们正在画画吗?
动词现在分词是动词原形变化而来的,规则变化如下:
动词ing形式叫动词现在分词,其构成如下:
1) 直接在动词后加ing
play—playing, do—doing, talk—talking, sing--singing
2)以不发音的字母e结尾的动词,先去e,再加ing
make—making, write—writing, have—having, take—taking
3) 以重读闭音节结尾的动词且词尾只有一个辅音字母,应双写这个辅音字母,再加ing run—running, stop—stopping, put—putting, swim—swimming
注意对现在进行时态的判断。判断一个英语句子用什么时态,主要看句子的时间状语,一般说来,每种时态都有与之相对应的时间状语。现在进行时表示现在(说话瞬间)正在进行或发生的动作。因此,这个时态最常用的时间状语是now;但有不少句子并没有now,只能通过提示语如look、listen等或者通过上下文来确定用现在进行时。
She is cleaning her room now. 她正在打扫房间。
Look! The girl is dancing over there. 看!那个女孩在那里跳舞。 --Can you go and play games with me? 你能和我们一起做游戏吗? --Can’t you see I am doing my homework? 你没看见我正在做作业吗?
