some & any：均可接可数 / 不可数名词 。some 常用于肯定句；any 常用于否定句、疑问句、条件从句 。但表请求、希望获肯定答复的疑问句（如 “Would you like some tea ” ）用 some 。
例：A: Are there any apples in the fridge
B: Yes, there are some. / No, there aren’t any.；
A: Is there any water in the bottle
B: Yes, there is some water. / No, there isn’t any water.
many & much：都表 “很多” 。many 接可数名词复数，much 接不可数名词 。
例：In the future, many people will live in outer space.；
There isn’t much water left in the bottle.；
I’m afraid the kids spend too much time online.
few/a few & little/a little：few/a few 接可数名词复数，little/a little 接不可数名词 。few/little 表 “很少；几乎没有”（否定含义 ）；a few/a little 表 “一些”（肯定含义 ） 。
例：We stayed in the old town for a few days.；
Don’t worry. There is a little time left.；
Few people know what happened.；
There is now little hope of success.
复合不定代词：由 some/any/no/every + -body/-one/-thing 构成（no one 除外，其他为一个词 ），相当于名词，可作主语、宾语、表语，作主语时视为单数 。若有定语，定语后置 。
例（作主语等 ）：Everyone says Yulong Mountain is beautiful.；
Nobody knows what the future will be like.；
I’m on vacation in Hangzhou and everything is fantastic.
例（定语后置 ）：Did you do anything fun on your holiday ；
I did nothing special.；

答案
一、选择题
1.A（否定句中用 any，表示请求建议的疑问句用 some ）
2.C（根据 “They like singing better.” 可知两人都不喜欢跳舞，neither 表示 “两者都不” ）
3.A（三个兄弟，all 用于三者及以上 “都” ）
4.C（根据 “I carried them by myself.” 可知没人帮忙，nobody 表示 “没人” ）
5.B（肯定句中表示 “一些东西” 用 something ）
6.B。第一空在否定句用 anything；第二空在肯定句表 “某事” 用 something 。
7.C。父母是两人，“都不喜欢流行音乐” 用 neither 。
8.B。“several plans”（几个计划，数量≥3 ），“each of...”（…… 中的每一个，作主语时谓语动词用单数 ），符合 “sounds great”（单数谓语 ）；all 作主语时谓语用复数，every 不能与 of 直接连用，both 用于两者，所以选 B 。
9.B。疑问句问 “有人” 用 anyone(不肯定） 。
10.A。肯定句中表 “有人” 可能错拿钢笔，用 someone 。
