Few students can understand the sentence until it ________ twice or three times.[ ]A. explains B. is explained C. will be explained D. has explained -九年级英语
而且,句子中有了助动词,谓语动词就不需要有任何变化了,即用动词原形表示。例:
We have six classes every day. 我们每天上六节课。
I often get up at 6:30. 我经常6:30起床。
Jack likes Chinese food very much.杰克很喜欢中国饮食。
We can see some pictures on the wall. 我们能看到墙上的画。
4.一般现在时常用的时间词语
常用于一般现在时的词语有 sometimes/usually/often/every day(week,year)/ now/always 等。
这些时间词语只是辅助作用,这些词语也可用于其它的时态,所以谓语动词变化才是最关键的。
注意:当表现强烈的感情色彩时,尽管有如 always/never/seldom 等频率副词,但一般在频率副词前加上be动词,后面变为动词的现在分词形式。
例:My father lose his key again. He is always losing his key.
一般现在时中当主语为第三人称单数的时,动词上要改为第三人称单数形式。
