一般现在时否定句构成
一般现在时否定句构成咱们都知道,英语里这一般现在时可挺重要的。
那一般现在时的否定句呢,就像是给一个原本规规矩矩的小世界里,添了点不一样的色彩。
一般现在时,就好比是一个每天按部就班工作的小机器人,总是按照固定的模式来描述事情。
比如说“我每天早上跑步”,这就是个典型的一般现在时的句子。
那否定句呢?就像是突然给这个小机器人下了个相反的指令,不让它按照原来的路数走了。
这一般现在时否定句的构成啊,对于动词的处理可有点门道。
要是句子里的动词是be动词,那可简单得很。
就像说“他是个好学生”(He is a good student),变成否定句就是“他不是个好学生”(He isn't a good student)。
这is变成isn't,就像把原本开着的灯给关上了,一下子就从肯定变成否定了。
你看,这多简单啊,就像从盘子里拿走一块糖那么容易。
可是啊,如果句子里的动词不是be动词,那就要费点小周折了。
这时候就得请出助动词do或者does来帮忙了。
这就好比是你要搬一个很重的箱子,自己一个人搬不动,得找个人来搭把手。
比如说“我喜欢苹果”(I like apples),要变成否定句呢,就不能直接说“I not lik e apples”,这可不对哦。
得变成“I don't like apples”。
这个don't就像是一个小魔法,把原本肯定的意思给否定了。
如果主语是第三人称单数,像“他每天看电视”(He watches TV every day),变成否定句就是“He doesn't watch TV every day”。
这里的doesn't就像是一个小卫士,站在动词前面,把肯定的动作给拦住了,不让它发生。
咱们再举个例子吧。
就像有个小花园,里面种满了各种各样的花。
“这些花是红色的”(These flowers are red),这是个一般现在时的句子。
如果说“这些花不是红色的”(These flowers aren't red),这就成了否定句,就像把花园里红色的色调给换成了其他颜色,整个画面都不一样了。
