这里是考查分数的表达,分数的表达口诀:子基母序,分子大于一,分母加s。

2.C解析:C【解析】句意:第23届冬季奥运会将与2018年2月9日在韩国平昌举行。

twenty-three23,是基数词; nine 9,是基数词。

twenty-third第23,; ninth第9,表示第几届奥运会,用序数词,第二十三为twenty-third。

表示具体日子,用序数词,表示9日用ninth。

故选C。

3.C解析:C【解析】句意:——许多年轻的人们在二十世纪八十年代来到深圳。

他何时来到深圳的?——当他还是一个八岁的小男孩的时候,他和他的父母来到这儿。

短语in+the+年号的复数,表示多少世纪多少年代;eight-year-old是符合形容词,eight是以元音音素开头的,这里用不定冠词an。

根据题意,故选C。

点睛:定冠词及基数词表示的世纪加十位整数的复数形式构成in the 1930's(in the thirties of the twentieth century或 in the nineteen thirties)在二十世纪三十年代4.D解析:D【解析】试题分析:句意:---你什么时候开始收集邮票的?---当我七岁大的时候收集了第一张邮票。
