你仔细看看下面的细解,若有问题继续追问啊.
1.当主语部分含有with,together with,along with,as well as,besides,except,but,like
等介词或介词短语时,谓语动词用单数形式；但“名词+as well as+名词”时,谓语动词一般应与第一个名词一致.
Mike with his father has been to England.迈克同他的父亲去过英格兰.
Mike,like his brother,enjoys playing football 迈克像他的哥哥一样喜欢踢足球.
The students as well as the teacher were present at the meeting.
2..由and连接的两个单数名词作主语时,一般用复数形式,但and所连接的并列主语是同一个人,事物,或概念时,谓语动词用单数.这两种情况区分如下：a/the+单数名词+and+单数名词,指的是同一个人或物；a/the+单数名词+and+a/the+单数名词,指两个人或物.
