ACT阅读迷惑词汇——until，你掌握了吗？

　　为了搞定ACT阅读，应试者必须明白他们将要面对的问题类型，以及怎样成功解决它。这其中最大的问题就是词汇问题。今天课窝网带大家一起来了解一下，阅读中的一个大难词：until

　　先看一道例题：

　　The most celebrated natural antagonism between sperm whales and squid almost certainly involves the jumbo squid’s larger cousin, the giant squid, a species that grows to 65 feet long. The relationship between sperm whales and squid is pretty dramatic. A single sperm whale can eat more than one ton of squid per day. They do eat giant squid on occasion, but most of what whales pursue is relatively small and over-matched. With their clicks, sperm whales can detect a squid less than a foot long more than a mile away, and schools of squid from even farther away.But the way that sperm whales find squid was until recently a puzzle.

　　40. Which of the following statements about the mystery of how sperm whales locate squid is best supported by the passage?

　　F.The mystery was solved in the 1800s.

　　G.The mystery was solved recently.

　　H.The mystery is likely to be solved in the near future.

　　J.The mystery is likely to remain unsolved until better technology is invented.

　　虽然是个定位题，但是这个题目其实考察的是大家对于“until” 的理解，很多同学的印象中，“until” 就是“直到”，“直到现在还是一个谜”。那答案好像妥妥的是J了，或者H也有点像？

　　让我们先来看一看 Collins 词典对于这个词的英文解释（PS：强烈推荐大家在遇到看不明白的词的时候，多查一查英英词典）

　　Until

　　If something happens until a particular time, it happens during the periodbeforethat time andstopsat that time.

　　这句话里最重要的两个词，一个是before；一个是stop。

　　它表明 until 是之前发生的，并且在此刻停止了。

　　带到文章中，until recently：在现在之前是一个谜，并且现在已经停止成为一个谜了。

　　所以，这题的答案华丽丽的应该选G答案。

　　55C

　　In the eighteenth and nineteenth centuries, travelers in North America reported seeing armies of squirrels, sometimes numbering in the thousands, making their way across fields, forests, and rivers.These movements continued to amaze and appall the citizenry until the squirrels’ habitat, deciduous forest, was greatly reduced in the late 1800s.

　　“在deciduousforest was greatly reduced”之前，松鼠的迁徙让人们感到震惊，并且暗含了一层意思，在此之后，松鼠就没有那么令人震惊的迁徙了。

　　37. What does the passage state eventually brought an end to the great squirrel migrations?

　　A.The end of nut crop fluctuations

　　E.A reduction of deciduous forests

　　F.The ability of squirrels to keep a centra larger

　　G.An increase in acorn and nut production

　　所以，这个定位题的答案为B选项

　　例如：

　　67B

　　When people think of lions, many probably picture a regal creature with luxuriant mane of blond hair overing its neck and shoulders. But a study suggests that the widespread image is misleading—that among male lions,a baldish head with sideburns may have been as prevalent in Africa as heavy manes, at least until recent years.

　　同理可得：以前，秃头的狮子和有鬃毛的一样常见，并且还有一层暗含的意思，“现在已经不那么常见了”

　　31. As described in the passage, Gnoske and Kerbis Peterhan’s study suggests that made lions with baldish heads and sideburns may in the past have been:

　　A.common in Africa but are now much less common on that continent.

　　B.rare in Africa but are now increasingly common in some regions of that continent.

　　C.uncommon in Africa but were predominant throughout the rest of the world.

　　D.predominant in Africa but were rare in other parts of the world.

　　所以这个题的答案应该为A。
