1. 【精析】选[B]。本题考查基数词的用法，这里的times相当于“乘以”。18要加后缀-teen。[A]项为“第八”；[C]项为“八十”，基数词；[D]项为“第八十”。
【句意】三乘以六得十八。
2. 【精析】选[D]。twelfth为不规则变化。[A]项为基数词；[B]、[C]两项变化不对。
【句意】名单上已经有十一个人了，你是第十二个。
3. 【精析】选[B]。在句子中用than连接，可以判断也应用序数词。[A]没有用序数词；[C]词性不对；[D]少冠词the。
【句意】第二个比第一个重。
4. 【精析】选[D]。本题考查表示“大约”之意的词的位置及用法，答案中的some相当于about，意为“大约”，应是放在数词之前。[A]、[B]两项当“大约”讲时接在数词后。approximate意为“大约的”，形容词，而这里“大约”应用副词approximately，表程度；some后接数词表示“大约”。
【句意】大约有两百人在这次撞车事故中丧生。
5. 【精析】选[A]。十位数加s表示“大约在那个年龄段”，teens在这里指十几岁的阶段。[B]项缺s；[C]项表示“十几岁的阶段”时不是用ten直接加s，而是用teen。
【句意】她大约十几岁。
6. 【精析】选[A]。over=more than，表“多于”。[B]项不完整，只有more than才能表达“大于”；less后要跟than才能表示“少”；[D]项意思表达重复。
【句意】这本书不止值40美元。
7. 【精析】选[B]。前一句已经说明现在是二点五十七分，即接近但仍没有到三点，所以用almost表示“没有到”。[A]项不符合题意，more than表示“不止”；[C]项虽然表“不到”，但一般用在年龄上；[D]项加than才表示“少于”。
【句意】现在是两点五十七分，快到三点了。
8. 【精析】选[A]。表示轻几倍，应满足“倍数+形容词/副词比较级+ than”的结构，所以用six times less，中间不应用连字符，six不应用序数词。
【句意】一个给定物体在月球上的重量是地球上的六分之一。
9. 【精析】选[B]。用as...as时要符合“倍数+as+形容词/副词+as”的结构。
【句意】约翰行李的重量只是玛丽行李的三分之一。
10.【精析】选[A]。根据“倍数+名词”这一结构，size为名词，但size of the moon（月亮的大小）是特定的，前面应加定冠词the，所以[D]项不对。而[B]、[C]两项中的large和small均为形容词，也不正确。
【句意】地球体积为月球的49倍。
11.【精析】选[D]。根据“动词+百分比或倍数”这一结构，rose（升高）为动词，应直接后接百分比（1.1%）（或用rise by 1.1%）。[A]、[B]、[C]三项均含介词at，应排除。
【句意】上个月的个人收入增长了1.1%。
12.【精析】选[B]。根据“动词+to+数词”这一结构，rose应后接介词to再加数词（2.5million）表示“增至（2.5 million）”。
【句意】去年利润增至二百五十万美元。
13.【精析】选[C]。“动词+by+数词/百分比，倍数”这一结构表示“增/减了多少”；本句表示被动意义，动词应用被动语态，且介词by不能省略，因此选[C]。
【句意】农业项目的花费将被削减掉一百四十九亿美元。
14.【精析】选[A]。double/triple/quadruple均为及物动词，其后应直接加名词，因此[A]为正确选项，表示“将……翻一番”；[B]项多了介词for；[C]项、[D]项缺谓语动词。
【句意】他们计划将投资额翻一番。
15.【精析】选[B]。表示分数时，分子“1”用基数词one，分母“3”用序数third，在后接名词时应加上of表示“……的三分之一”。
【句意】全班的三分之一是女孩。
16.【精析】选[A]。小数1.5应表示为“1+point+5”，因此选[A]。1.5大于1因此后面的pound（英镑）应用复数形式。[C]项为“五分之一”，与pounds这一复数形式不一致；[B]项缺介词of；[D]项这种表达法不存在。
【句意】买了箱子之后我只剩下1.5英镑了。
17.【精析】选[D]。百分比加名词表示“……的百分之……”时应使用介词of。

18.【精析】选[A]。a hint of表示“（细微的）迹象，少许”。
【句意】他说话的语调里有一丝不耐烦。
19.【精析】选[D]。所填词与200 words和research paper形成语义场同现，abstract意为“摘要”，指关于书的内容的简短描述，句中所说的显然应是研究论文的“摘要”。
【句意】作者被要求交研究论文时附上一篇200字的摘要。
20.【精析】选[C]。armful表示“一抱之量”，与cupful（一杯之量），handful（一手之量），bagful（一包之量）相比，最符合题意，所以只能选[C]。
【句意】她的朋友捧着一满怀的花来欢迎她。
21.【精析】选[A]。a fit of anger意为“一阵怒气”；flash表示“一闪”；stroke表示“一次（打击）”；display表示“一次（陈列）”。
【句意】他被一阵怒气冲昏了头。
22.【精析】选[C]。swarm多用于表示昆虫、乌等的“大群”，为最佳选项。

23.【精析】选[B]。此题考查表示“倍数”的固定句型。列举几种常用的句型：“倍数+what +从句”“倍数+ as...as”“倍数+名词词组”。
【句意】现在的产量是1990年前的六倍。
24.【精析】选[D]。本题考查的是倍数表达的固定结构：“倍数+ as + much/many/其他形容词、副词（+ as）”。
