大学英语六级考试作为大学期间的一门重要的考试，其中的阅读理解所占比重很大，虽然看起来文章很多，但题目并不多，是比较容易拿分的一块，所以对这一部分的复习一定不能松懈，考生平时要坚持练习，下面是一篇英语六级阅读练习，快来练练吧。

　　Some plants get so hungry they eat flies, spiders, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.

　　You've probably seen a Venus' flytrap. It's 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 stalks(茎)are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger(触发)hairs. 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 Society's Newsletter. Note: Despite any science-fiction stories(科幻小说)you 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 plants—well, most of the time.

　　All green plants make sugar through a process called photosynthesis(光合作用). 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(氮). Nitrogen is a nutrient that they can't obtain any other way. Why Almost all green plants on our planet get nitrogen from the soil"Meat-eating" plants can't. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity(酸度). So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to "meat-eating" plants. Never fertilize(施肥)them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll 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.Venus'flytrap 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

　　1.选D。本题为主要细节正误题。从第一段最后一句“In fact, they're 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 stories(科幻小说)you 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(氮). ”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。
