英语四级快速阅读专项练习（一）
【答案与解析】
1.N当出现all这种过于绝对的词语时，考生应该引起注意。一般这样的命题多数是不正确的。首段中有句话：“All spiders produce silk, but only some construct webs to catch their hcmes……”命题中all的说法过于绝对。
2.Y该命题是对原文第二段首句话的同义改写。
3.N原文中第二段首句中写到，“of the 600 spiders in Britain only 12 are strong enough to pierce the human skin”，因此并不是命题中说的当它们刺进人的皮肤通常能致人死亡。
4.N原文中说，“Arachne became depressed after this and in the end she hung herself.”注意代词this指代上面的句子，结合上一句一起理解，命题显然是错误的。
5. NG文章中只出现过一次Tim Tegenaria，所以该题很好定位，即最后一段的第二句。可是文章中并没有出现tarantula spiders.
6.Y该命题定位在最后一段倒数第三句话处。
7.NG首先定位Money spiders出现的位置是文章的最后的两句，可是并没有提到它是最小的。
8.32,000该题由关键词species of spider定位在第二段倒数第二句。
9.looking at their palps 该题定位在倒数第二段的首句。
10.the Goliath spider 本题答案在最后一段的首句。

Spiders
Spiders can be distinguished from other Arachnids because the prosoma （combined head and thorax） is only separated from the opisthosoma （abdomen） by a narrow waist, in other Arachnids the whole body appears to be much more of a single unit. All spiders produce silk, but only some construct webs to catch their homes and to protect their eggs.
All spiders possess poison glands but very few of them are dangerous to humans, of the 600 species in Britain only 12 （at least one of these is a recent human assisted colonist） are strong enough to pierce the human skin, and apart from allergies, none are more dangerous than a common wasp. Most spiders have 8 eyes （though some have 6,4,2 or 0）, as well as 8 legs. （By the way if you count the claws as separate leg section（which you shouldn't really）then their legs have 8 parts as well（coxa, trochanter, femur, patella, tibia, tarsus, metatarus, claws）. There are more than 32,000 known species of spider in the world. No human being has ever been officially recorder as having died as the result of atarantula'bite.
All spiders are carnivorous and feed only on liquids, i.e. their preys natural juices and the breakdown products of external digestion （meaning they spit, exude or inject digestive juices onto/into their prey and suck up the resulting soup）. So why not invite some to your next social do?
What's In a Name
The word Arachnida comes from the Greek word Arachne, who was the daughter of Idmon of Colophon in Lydia, a dyer by trade. Arachne herself was a weaver, the best in all the known world. However in a foolish moment she challenged Athene, the daughter of Zeus and goddess of, among other things, waving to a weaving competition. Arachne wove so perfect a cloth that she tore it to shreds. Arachne became depressed after this and in the end she hung herself. Athene stirred to remorse at the knowledge of what her anger had wrought turned the rope Arachne had used to hang herself into a web and Arachne herself into a spider so that the beauty of her spinning should not be lost to the world ever again.
The Great Household Spider Safari
There are just over six hundred different sorts of spiders in the British Isles. But of these only a handful are commonly found in houses. At the front of the head are a pair of what appear to be small legs. These are called palps and are used to guide food to the spider's mouth. The front of the head also has a group of six or eight eyes. On the underside of the body at the rear, are four or six small conical bumps or cylinders. There are the spinnerets from which the spider produces the silk to make its webs.
Telling male and female spiders apart is easily done by looking at their palps. Males have swollen ends to their palps which makes them look as if they are wearing boxing gloves, these are often strange shapes if looked at with a hand lens. Females have normal looking palps that are not swollen at the ends.
