2007年12月英语六级考试阅读的冲刺模拟训练5

Some plants get so hungry they eat flies, spiders, and even small frogs. Whats more amazing is that these plants occur naturally in every state. In fact, theyre found on every continent except Antarctica.

  Youve probably seen a Venus flytrap. Its often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalksare specially modified leaves that act like traps. Inside each trap is a lining of tiny triggerhairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.

  The Venus flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Societys Newsletter. Note: Despite any science-fiction storiesyou might have read, no meat-eating plant does any danger to humans.

  Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: attract, kill, digest, and absorb some form of insects , including flies, butterflies, and moths. Meat-eating plants look and act like other green plantswell, most of the time.

  All green plants make sugar through a process called photosynthesis. Plants use the sugar to make food. What makes meat-eating plants different is their bug-catching leaves. They need insects for one reason: nitrogen. Nitrogen is a nutrient that they cant obtain any other way. Why Almost all green plants on our planet get nitrogen from the soilMeat-eating plants cant. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity. So theyve come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to meat-eating plants. Never fertilizethem! But dont worry, either, if they never seem to catch any insects. They can survive, but theyll grow very slowly.

  Questions 1 to 5 are based on the passage above.

  1.According to the passage,carnivorous plants_____.

  A.only grow in wild filed B.are rare to see

  C.are as common as flies D.cannot grow on Antarctica

  2.Venusflytrap preys on insects by_____.

  A.its numerous elongated stalks B.a container where it grows

  C.its insect-catching leaves D.the lining of tiny trigger hairs

  3.We can conclude from the third paragraph that_____.

  A.carnivorous plants are dangerous

  B.carnivorous plants are fictional

  C.carnivorous plants occasionally eat books

  D.carnivorous plants are harmless to humans

  4.Carnivorous plants eat insects in order to_____.

  A.make sugars through photosynthesis

  B.obtain a nutrient called nitrogen

  C.make food and nectar

  D.develop to a more advanced form

  5.In the eyes of the author,which of the following statements is TRUE?

  A.Carnivorous plants cannot grow in acid soil.

  B.Carnivorous plants can grow in nutrient-poor soil.

  C.Carnivorous plants will die if they cannot catch any insects.

  D.Carnivorous plants can get nitrogen from nutrient-rich soil

  D.Carnivorous plants can get nitrogen from nutrient-rich soil

  斟词酌句

  4.extract vt. 提取,提炼,榨取;取出,抽出,拔出;获得,索取;摘录,抄录

  n. 摘录,选段;提出物,精,汁

  指点迷津

  1.[Whats more amazing] is [that these plants occur naturally in every state]. 在本句中,第一个方括号里what引导的从句做主句的主语;that引导的从句做整个句子的表语。

  2.At the end of its stalksare specially modified leaves [that act like traps]. 本句为倒装句。句子的主语是 specially modified leaves,谓语动词是arethat引导的定语从句修饰leaves。

  试题精析

  1.选D。本题为主要细节正误题。从第一段最后一句In fact, theyre found on every continent except Antarctica.可知,食肉植物不能在南极洲上生长。

  2.选C。本题为主要细节正误题。第二段说 When an insect lands on them, the trap suddenly shut.其中trap是指specially modified leaves that act like traps,由此可知,捕蝇草是靠叶子捕捉昆虫的。

  3.选D。本题为观点态度推断题。从第三段最后一句Despite any science-fiction storiesyou might have read, no meat-eating plant does any danger to humans.可知,食肉植物不会对人类构成威胁。

  4.选B。本题为主要细节正误题。从第五段中的They need insects for one reason: nitrogen. 可知B选项为正确答案。

  5.选B。本题为观点态度推断题。第五段说 In fact, nutrient-rich soil is poisonous to meat-eating plants.,由此可推断,食肉植物不能在养分丰富的土壤中生长,反而能在缺乏养分的地方生长。

  全文翻译

  有些植物非常饥饿,它们会吃下苍蝇、蜘蛛甚至小青蛙。更让人惊讶的是,美国的每个州都有这些植物。事实上,除了南极洲以外,在每个大陆都能找到它们。

  你可能见过捕蝇草吧。博物馆的礼品店,百货商场甚至超市都常有出售。它是一种小型植物,在花盆里长到6-8英寸高。在它又多又细的茎的底部有经过特殊变异的叶子,可充当捕蝇夹。每一个捕蝇夹的内壁是一层细微的绒毛触发器。当虫子落在上面,捕蝇夹就会叭的一声合上。在随后大约一周的时间里,捕蝇草就吃它的捕获物。

  巴利迈耶斯-莱丝说,捕蝇草只是500多种食肉植物之一。他是《国际食肉植物协会业务通讯》的编辑。请注意:不管你看过怎样的科幻小说,没有一种食肉植物会对人类构成威胁。

  迈耶斯-莱丝博士说,一种植物只有全部具备了下列4种功能才算是食肉植物:引诱、捕杀、消化、和吸收某种捕获物。捕获物包括苍蝇、蝴蝶和飞蛾等许多喜欢花蜜的昆虫。食肉植物的外观和生长方式都与其他绿色植物没有什么两样当然,这是指在大部分时间里。

  所有的绿色植物通过光合作用制造糖。它们利用糖制造食物和花蜜。食肉植物与众不同的是它们的叶子能捕捉昆虫。它们捕杀昆虫的理由只有一个:氮。氮是一种它们无法用其他方法获取的养分。这是为什么呢?地球上几乎所有的绿色植物都是从土壤中获取氮。食肉植物却不行。它们生长在酸性强的土壤里,很难甚至几乎无法从土壤里吸取养分。因此它们就靠从昆虫和小动物身上获取氮。其实,养分丰富的土壤对食肉植入是有毒的。千万别给它们施肥!不过,如果这些食肉住屋真是捕捉不到昆虫的话,也不用担忧。它们能活下去,只不过生长缓慢而已。
