2014高考英语阅读理解抓分训练题（38）及答案阅读理解if you travel to a new exhibit at the san francisco conservatory of flowers, you will have chances to see some meat-eating plants. take bladderworts, a kind of such plant, for example. they appear so small and grow in a quiet pond. but these are the fastest-known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!once the trap door closes on the victim, the enzymes(酶) similar to those in the human stomach slowly digest the insect. when dinner is over, the plant opens the trap door and is ready to trap again.meat-eating plants grow mostly in wet areas with soil that doesn t offer much food value. in such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. north america has more such plants than any other continent.generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers (a container like a bottle) full of nectar(花蜜)the asian pitcher plant, for example, has bright colors and an attractive half-closed lid. curious insects are tempted to come close and take a sip, and then slide down the slippery (光滑的)slope to their deaths.hair-like growths along the pitcher walls ensure that nothing cab escape, and the digestive enzymes can get to work. a tiny insect can be digested in a few hours, but a fly takes a couple of days.some of these pitchers are large enough to hold two gallons. meateating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn t a good place to get a drink.【文章大意概括】本文是一篇说明文，介绍了一些特别的植物靠捕食动物获得生长所需养分的“食肉植物”。1from the first paragraph, we

second【详解剖析】细节理解题。第一段指出，bladderworts能在1/50秒的时间内捕获一只小昆虫，是植物中已知的捕获动物速度最快的，因此选b。【最佳选项】b2if the trap door of a meateating plant is closed, the plant _.a. is fooling insects into taking a sipb. is producing nectarc. is tempting insects to come closed. is enjoying a dinner【详解剖析】细节判断题。第二段说，一旦“陷阱门”将猎物关起来，类似于人胃里的那些消化酶就开始慢慢地消化它了，由此判断d正确。【最佳选项】d3meateating plants can grow in wet and poor soil because they _.a. can get nutrition from animalsb. don t need much food valuec. can make the most of such conditionsd. have developed digestive enzymes【详解剖析】推理判断题。这些植物生长在潮湿贫瘠的土壤中，为获得生长所需的养分，在数千年的进化中，它们演化出了捕获昆虫的“陷阱”，由此推出它们主要从动物中获取养分，而不是从土壤中获取养分。【最佳选项】a4which of the following is the picture of the asian pitcher

way, hundreds of new words were introduced into english and spanish vocabularies. today life is changing very fast, and language is changing fast too. there are several major(主要) language families in the world. some scientists say there are nine main families, but other scientists divide them differently. the languages in each family are connected, and scientists think that they came from the same

most important food crops. they are also one of the most valuable exports. bananas do not grow from seeds. instead, they grow from existing plants. bananas are threatened by disease because all the plants on a farm are copies of each other. they all share the same genetic weaknesses. for example, the cavendish banana is most popular in north american and european markets. however，some kinds of fungus organisms easily infect the cavendish. black sigatoka disease affects the leaves of cavendish banana plants. the disease is controlled on large farms by putting chemicals on the plant s leaves. farmers put anti-fungal chemicals on their crops up to once a week.another fungal disease is more serious. panama disease attacks the roots of the banana plant. there is no chemical treatment for this disease. infected plants must be destroyed. panama disease has affected crops in southeast asia, australia and south africa. there is concern that it may spread to bananas grown in the americas. this could threaten an important export product for central and south america.the international network for the improvement of banana and plantain supports research on bananas. the group has headquarters in france and other offices in the major banana-growing areas of the world. the group says that more research must be done to develop improved kinds of bananas. the group says that fungal diseases mainly affect only one kind of banana. in fact, there are five hundred different kinds of bananas. food and agriculture organization of the united nations has said that the cavendish banana represents only 10% of world production.the un. agency says farmers should grow different kinds of bananas. this protects against diseases that affect only one kind. experts warn that disease may cause the cavendish banana to disappear. this happened earlier to another popular banana because of its genetic weakness against disease.【文章大意概括】香蕉由于遗传性的抗病弱点，在不久的将来有的品种可能会消失。文章列举了两种威胁cavendish香蕉的真菌病，国际组织建议农民种植更多种类的香蕉。1what does this passage mainly tell us?a. bananas are the world s most important food crops.b. the risk to a
