主语是单数,其后有 with,together with,along with,as well as,besides,but,except,including,in addition to,like,no less than,rather than 或“ of ＋名词”等短语,谓语动词仍然用单数形式,例如：
（ 1 ） The father with his two sons has gone to the cinema.
（ 2 ） No one except the two boys was late for class.
（ 3 ） Li Ming,rather than his classmates,has let out the secret.
所以应该是agrees
