问题描述:

148.Every day the boy,together with his classmates,---to go to the sports ground and --- football,---themselves.
A.are noticed,play,enjoying
B.is noticed,plays,enjoying
C.are noticed,plays,enjoys
D.is noticed,play,enjoying

答案:B
解析:这句话的主语是the boy,后面的together with his classmates 是状语,所以谓语动词也要用第三人称单数形式,and 连接的是并列结构,后面的也应该是第三人称单数形式,即plays,还有后面的enjoying 是现在分词作伴随状语.
翻译:我们注意到每天这个男孩和他的同学都去操场踢足球,玩得很开心.
