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

　　指點迷津

　　1.[Whats more amazing] is [that these plants occur naturally in every state]. 在本句中，第一個方括號里what引導(dǎo)的從句做主句的主語;that引導(dǎo)的從句做整個句子的表語。

　　2.At the end of its stalksare specially modified leaves [that act like traps]. 本句為倒裝句。句子的主語是 specially modified leaves，謂語動詞是arethat引導(dǎo)的定語從句修飾leaves。

　　試題精析

　　1.選D。本題為主要細節(jié)正誤題。從第一段最后一句In fact, theyre found on every continent except Antarctica.可知，食肉植物不能在南極洲上生長。

　　2.選C。本題為主要細節(jié)正誤題。第二段說 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，捕蠅草是靠葉子捕捉昆蟲的。

　　3.選D。本題為觀點態(tài)度推斷題。從第三段最后一句Despite any science-fiction storiesyou might have read, no meat-eating plant does any danger to humans.可知，食肉植物不會對人類構(gòu)成威脅。

　　4.選B。本題為主要細節(jié)正誤題。從第五段中的They need insects for one reason: nitrogen. 可知B選項為正確答案。

　　5.選B。本題為觀點態(tài)度推斷題。第五段說 In fact, nutrient-rich soil is poisonous to meat-eating plants.，由此可推斷，食肉植物不能在養(yǎng)分豐富的土壤中生長，反而能在缺乏養(yǎng)分的地方生長。

　　全文翻譯

　　有些植物非常饑餓,它們會吃下蒼蠅、蜘蛛甚至小青蛙。更讓人驚訝的是，美國的每個州都有這些植物。事實上，除了南極洲以外，在每個大陸都能找到它們。

　　你可能見過捕蠅草吧。博物館的禮品店，百貨商場甚至超市都常有出售。它是一種小型植物，在花盆里長到6-8英寸高。在它又多又細的莖的底部有經(jīng)過特殊變異的葉子，可充當(dāng)捕蠅夾。每一個捕蠅夾的內(nèi)壁是一層細微的絨毛觸發(fā)器。當(dāng)蟲子落在上面，捕蠅夾就會叭的一聲合上。在隨后大約一周的時間里，捕蠅草就吃它的捕獲物。

　　巴利邁耶斯-萊絲說，捕蠅草只是500多種食肉植物之一。他是《國際食肉植物協(xié)會業(yè)務(wù)通訊》的編輯。請注意：不管你看過怎樣的科幻小說，沒有一種食肉植物會對人類構(gòu)成威脅。

　　邁耶斯-萊絲博士說，一種植物只有全部具備了下列4種功能才算是食肉植物：引誘、捕殺、消化、和吸收某種捕獲物。捕獲物包括蒼蠅、蝴蝶和飛蛾等許多喜歡花蜜的昆蟲。食肉植物的外觀和生長方式都與其他綠色植物沒有什么兩樣當(dāng)然，這是指在大部分時間里。

　　所有的綠色植物通過光合作用制造糖。它們利用糖制造食物和花蜜。食肉植物與眾不同的是它們的葉子能捕捉昆蟲。它們捕殺昆蟲的理由只有一個：氮。氮是一種它們無法用其他方法獲取的養(yǎng)分。這是為什么呢?地球上幾乎所有的綠色植物都是從土壤中獲取氮。食肉植物卻不行。它們生長在酸性強的土壤里，很難甚至幾乎無法從土壤里吸取養(yǎng)分。因此它們就靠從昆蟲和小動物身上獲取氮。其實，養(yǎng)分豐富的土壤對食肉植入是有毒的。千萬別給它們施肥!不過，如果這些食肉住屋真是捕捉不到昆蟲的話，也不用擔(dān)憂。它們能活下去，只不過生長緩慢而已。
