【参考答案】
11. [答案]：A 表示“某人几十岁”，用“in one's十位数的基数词的复数形式”。故选A。
12. [答案]：A “每隔……”的表达式为：“every +基数词+复数名词 /every +序数词+单数名词”。 13. [答案]：D news表示“消息”，是不可数名词;一条消息应用，a piece of ;两条消息则用two pieces of。故用D。
14. [答案]：B 。a number of, 意为“许多…”，后接复数名词，谓语用复数形式;the number of意为“为……的总数”，后接复数名词，但谓语要用单数。当分子大于“1”时。分母的序数词后加“s”。分数常与of 短语连用，作主语时，其谓语动词的单复数取决于of 后的名词。故选B。
15。 [答案]：A 由基数词和名词加连字符号构成的复合词作定语时，其中名词用单数。反之，则用复数。
16. [答案]：A 。ten，hundred，thousand，million，billion表示具体数目时，不用复数形式。先排除B、D;among表示“在.......中”，指三者或三者以上;而between则表示“两者之间”。故选A。
17. [答案]: D。ten，hundred，thousand，million，billion表示具体数目时，不用复数形式。但ten，hundred，thousand，million等后面如跟“of......短语”时，则其后要用复数形式，表示大约数。故应选D。
18. [答案]:B 分数表达法是分子用基数词，分母用序数词。当分子大于“1”时。分母的序数词后加“s”。依据题意：四分之一加二分之一是多少?其答案应为：四分之三。故选B。
19. [答案]: C 分数表达法是分子用基数词，分母用序数词。当分子大于“1”时。分母的序数词后加“s”。
20. 【答案】A。 数词、形容词连用，修饰名词时，数词放在形容词前。
