答案及解析
一、语法填空
1.答案：nineties
解析：in one's nineties为固定表达,意为“某人九十多岁的时候”。
2.答案：what
解析：考查倍数表达的固定句型。句意：令这对夫妇感到欣慰的是，他们现在的收入是五年前的两倍。“A+谓语+倍数+what从句”是倍数表达法之一，句中double为形容词，相当于twice as much as...。故填what。
3.答案：billions
解析：考查数词的用法。句意:每天有数十亿人浏览这个网站。billions of表示“数十亿”。故填billions。
4.答案：third
解析：考查词形转换。句意：这是我第三次来南京。根据句意，the跟序数词连用表示“第几次”。故填third。
5.答案：thirds
解析：three"三",基数词,在英语中,表示分数时,分母数字用序数词表示,如果分子数字大于一,则分母序数词要加s,故三分之二应译为two thirds。故填:thirds。
6.答案：fifths
解析：考查分数表示法。分析句子可知，此处是指“五分之三”。英语中，分数的分子用基数词，分母用序数词，且当分子大于一时，分母要用复数形式。故填fifths。
7.答案：other/second
解析：考查数词。句意：他每隔一天回家一次，从来没有放弃过。此处表示每两天一次。中间次数可以修改，但day的单复数形式一定要相应改变。故填other/second。

二、单选题
11.答案：B
解析：考查分数表达法。句意:大约三分之二的地球表面被水覆盖。分数表达法的规则是:分子基数词，分母序数词，分子大于1，分母加s。故选B项。
12.答案：D
解析：考查分数和主谓一致。句意：我们班三分之二的学生打算去北京参加夏令营。分数用基数词作分子，序数词作分母，分子大于1时，做分母的序数词用复数，因此三分之二的表达应该是Two thirds；分数做主语时，谓语动词的单复数由分数指代的名词的数决定，本题分数指代的名词students是复数，因此谓语动词应该用 are。故选D。
13.答案：D
解析：本题考查最高级。句意: "黄河是我国第二长河。"longest前加序数词 the second 表示河流长度排序第二。
14.答案：C
解析：本题考查序数词及节日常识。表示 “第几”要用“定冠词the十序数词”。

16.答案：C
解析：考查介词短语及名词词义辨析。句意：四十多岁的加拿大医生诺尔曼·白求恩打破了国界，致力于帮助身处战争中的中国人民。occupation职业；intention意图；dedication奉献；commitment承诺。根据句意可知，第一个空格处考查了介词短语“in one's +数字复数”表示“在某人几十岁的时候”；第二个空格处表示的意思是“白求恩大夫致力于帮助中国人民”，C项“dedication”（奉献）符合句意。故选C项。
17.答案：C
解析：考查倍数表达法。句意：你最好乘火车去那儿。火车票比飞机票便宜三倍。倍数表达的三种方法：1.倍数+as…as…，2.倍数+比较级+than…，3.倍数+the size / length / width / height / age等名词+of…。three times cheaper than属于第二种表达，故选C。
18.答案：A
解析：考查倍数的表达。句意：据报道，工作要求高的女性患心脏病的可能性几乎翻一番。此处表示倍数关系，应用“倍数+as+形容词或副词的原级+as+其他”的固定结构，句中省略了“as+其他”，A项twice as likely符合题意，表示“可能性翻一番”。故选A。
19.答案：C
解析：考查数词辨析。句意：——打扰一下，你能告诉我去最近的火车站的路吗？——对不起，我不知道。我是新来的，这是我第一次来这里。A.one一个，基数词，表示数量；B.once一次，表示次数；C.first第一，序数词，表示顺序；D.two两个，表示数量。根据上文I’m new可知，我是第一次来。故选C。

22.答案：A
解析：考查数词的用法。句意：12月是一年的第十二个月，它是一年的最后一个月。结合句意可知，第一个空应该用序数词，而第二个空用last。故选A。
