解析：
11. Every + n and every +n ; Each + n and each +n ; No + n and no +n 作主语时，谓语动词用单数形式。
12. each of + 复数代词作主语，谓语动用单数。复数代词+each作主语，谓语动词用复数。
13. all 作为主语，代表人物时，一般用作复数；代表整个事件或情况时，一般看作单数。
14. “the+ 形容词/-ed分词”，表示一类人时，谓语动词用复数形式；表示一类事物时，谓语动词用单数形式。如：The good in him outweighs the bad.
15.分数（百分数）/ all / some / none / half / most+ of + n 做主语，谓语动词根据of后的名词来确定。
16. 英语中有一些由两个部分组成的物体名称通常是以-s结尾，如shoes, scissors(剪子)，pincers(钳子)，glasses(眼镜），shorts(短裤)，trousers(裤子)，suspenders(吊裤带)等。这一类名词，如果不带一把、一副、一条等单位词而单独使用，通常作复数。例如：
如果带有单位词，则由单位词的单、复数形式决定动词的单、复数形式。例如：One pair of scissors isn't enough.
17. A large quantity of + 可数名词复数形式/ 不可数名词，作主语时，谓语动词用单数形式；Large quantities of +可数名词复数形式/ 不可数名词，作主语时，谓语动词用复数形式。
18. 不定式、-ing形式短语或名词性从句作主语时，谓语动词常用单数。注意：当what引导的从句作主语，且表语为名词时，谓语动词的数常由表语的数来决定。
19. 英语中一些形复意单的名词，如：news, means, politics, physics, maths, the United States等作主语时，谓语动词用单数。但若不是国名，而是群岛、山脉、海峡、瀑布等地理名称、通常作复数用。
20. 用and 连接的成对名词习惯上被看成是一个整体，如：bread and butter(抹黄油的面包)，knife and fork(刀叉)，等作主语时，谓语动词常用单数。
