下面的题选什么? 1.There aren’t enough chairs here for us all. please bring _____one. 选项:other ,another, extra 2.It has sailed across the Alantic many times . It has sailed across the Alantic ____. 选项:Sometimes, always, often, usually 最好给解释一下
1.another (已经有一些再要增加的话,尤其是三个以上当用another,而不是other.而如果用extra的话则应该是please bring an extra one.) 2.often (sometimes与句意不符,always不用于句尾,usually也是很少用于句尾的,只有often和句意一致而且能放在句尾)
