问题描述:
Mr.Sawyer usually reads his newspaper,but sometimes he and his wife watch television.
watch 前面为什么不加are?
答
一般现在时的句子中如已经有谓语动词,不用be,如没谓语动词,用be 动词。如:
He is a worker.
I'm from England.
夲句已经有谓语动词watch,故没有are。
答
这句话整句都是正常语态,时态
sb do sth
或者是sb be doing sth
如果加are,watch就要改成watching, 但本句只能用watch
答
如果用are的话,就应该是are watching,表示现在进行时,就是现在正在看电视.
而watch是一般时态,指得是常常会这样做.sometimes就是明显的一般时态的标志
答
说一个习惯(usually 这可以看出),用现在时态来描述。时态和前面read一致。这个时态不加助动词。
进行时的时候才会加 are 但是是watching 而不是watch了就。
