1.“a number of+名词复数”作主语,谓语用复数；“the number of+名词复数”作主语,谓语用单数。
The number of mistakes is surprising.
The number of people hurt in the traffic accident has increased to 95,the news agency reports.
2.主语后跟with,together with,along with,but,except,besides,as well as,rather than,including,no less than,as much as等短语,谓语与前面的主语保持一致。
An iron and steal works,with some satellite factories,is to be built here.
Tom,along with his friends,goes skating every Saturday.
①—Dr.Johnson,together with his assistants,is coming to visit our school.
解析:考查主谓一致。若句中含有together with,together,as well as时,其句中谓语动词的选择要视其前的主语而定。
②John as well as the other children who have no parents is being taken good care of in the center.
解析:考查主谓一致和动词时态。who引导的定语从句修饰other children所以谓语动词应是复数；名词1+as well as/besides/with/together with ect.+名词2时,谓语动词要根据就远原则由名词1决定,所以第二空谓语动词为单数,约翰正在受到照顾,应用正在进行式的被动形式。
③All the workers except Jack are allowed to work at home.
解析:题意为:除了杰克允许所有工人在家办公。except后的主语为假性主语。句子主语是all the workers指人,故谓语动词用复数形式。
