(这个消息令人兴奋)5、glasses, shoes, socks, trousers, gloves等名词往往用复数形式,故谓语用复数.如:The trousers are very cheap and I want to take them.(裤子很便宜,我想买)6、a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式.如:A lot of students are playing baseball now.(现在有许多学生在打垒球) A lot of time was wasted on that work.(大量的时间花在了那个工作上)(被动句)7、and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数.如:The teacher and his son are picking apples now.(老师和他的儿子在摘苹果) / Fish and chips is very famous food.
