5题你都答对了.但是能不能说下理由
追答1主语从句谓语常用单数。2.分数指人时用复数 3. 复合名词在主题名词后加s grown-up s 例外。
4.留言，用单数，视为不可数 keep one's word 遵守诺言 固定短语 5. bad manners 短语 没有礼貌
6. B 不可数名词food 用a great deal 修饰。谓语用单数 。 7.C 倒装句 主语是two pictures
2.one-third 貌似是指computer把?
是不是和but有什么关系?
4.为什么不能用the word?
5.bad manner不对么?
6.这题答案是选a..我个人觉得答案错了
7.pictures不是被挂的么?难道hang是主动表被动?
指电脑数量
word 抽象意义不加冠词
a bad manner 可以
a 答案错了，large quantities of ...作主语，谓语用复数。
hang 用主动表示被动。
