单数的不它不在怎么写( 四 )


1) There is a big tree in front of my house. (肯定句)
There isn't a big tree in front of my house. (否定句)
Is there a big tree in front of your house? (疑问句)
Yes, there is. / No, there isn't. (回答)
6.谓语动词的单数形式是不是在谓语后加s选b
neither 。。。nor 表示两者都不,用这个短语的时候就是把它看成单数的,就像那些不定代词做主语一样,谓语动词都要用单三的,比如一句很经典的话:nothing is too difficult if you put your heart into it.这里就是不定代词做主语,用单三,这句话的翻译是“亨利的爸爸妈妈都不说英语,都说汉语” 。。
至于你的第二个问题,speak为何不加s呢?你知道情态动词吗?跟你说,情态动词就是像must,can,may,will之类的,后面要加动词原形,“he can speak and write english very well.”这句里面有can,所以用动词原形,不加s,这么讲理解吗?
