1、專題限時訓(xùn)練(二十二)史地自然型閱讀理解(二)(限時：25分鐘)(一)Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.Some

2、plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grasseating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.

3、Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animals teeth.Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unplea

4、sant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛蟲) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine disc

5、ourage the caterpillar.Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.1The

After all，animals do，too. “Fear matters，”says Karen Warkentin，an ecologist.“Its

9、a good thing，” she adds, “because fear makes you do things that keep you alive.”Like kids，many animals experience fear and they respond to the feeling in variety of ways.A frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big，hungry fish approaches.Some an

10、imals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying redeyed tree frogs in Costa Rica.In this species，female frogs attach jellylike clumps(果凍一樣的塊狀物)of

11、their eggs to the undersides of leaves.The leaves hang on branches that dangle(懸掛)over ponds.After they hatch from the eggs，the tadpoles(蝌蚪)then fall into the water，where they eventually grow into adult frogs.Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is

12、 about to attack，however，they can hatch up to 2 days ahead of the schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.If hatching early helps protect redeyed tree frogs from snakes，you might wonder why their eggs dont always hatch sooner.It turns out th

13、at hatching early brings its own danger.Once tadpoles land in the water，hungry fish and other animals like to eat them, too.Staying in their eggs for 6 days，then，allows frog embryos(胚胎)to grow big and strong.This extra growth improves their chances of surviving in the water.1It can be inferred from

17、.(三)Earlier this year, the Environmental Protection Agency proposed a stricter nationwide health standard for smogcausing pollutants that would bring substantial benefits to millions of Americans. With a final rule expected by the end of this month, some opponents, mainly from industrial and oilprod

18、ucing states, are pushing back. They say investments required to produce cleaner air are too expensive and not scientifically justified.Lisa Jackson, the EP.A.administrator, needs to stick to her guns. This is only the first of several political tests to come this fall, as she also seeks to tighten

19、rules governing individual pollutants like mercury and global warming gases like carbon dioxide.The health standard she is proposing covers groundlevel ozone, commonly known as smog, which is formed when sunlight mixes with pollutants from factories, refineries, power plants and automobiles. Ozone i

It had been recommended by the agencys independent scientific panel but rejected by the Bush administration, which proposed a weaker standard.Industry will have to make investments in cleaner power plants, and new technologies may be required. As it is, about half the countries that

23、of a recession (蕭條). But the health benefits, EP.A.says, far outweigh the costs, and the time frame for compliance is generous.1Why are some people strongly against a stricter limitation of smogcaused pollutants?ABecause they have to live a poorer life.BBecause they think they have to spend more mon

27、each.”可知D項正確。2B細(xì)節(jié)理解題。根據(jù)第三段中“Some plants，such as the oak tree，have thick and hard leaves that are difficult for animals to eat.”可知。故B項正確。3C細(xì)節(jié)理解題。根據(jù)第四段中“When a caterpillar (毛蟲) bites a tobacco leaf，the leaf produces a chemical messenger.This messenger sends to the roots the information to produce more

28、 nicotine.”可知樹根分泌出更多的nicotine。故C項正確。4B主旨大意題。本文主要講述的是不能移動的植物是如何保護(hù)自己的。故B項正確。(二)【要點(diǎn)綜述】本文主要論述的是恐懼是人類和動物常見的一種現(xiàn)象，有時恐懼是一件好事。動物對于恐懼的反應(yīng)是不同的，有些反應(yīng)方式甚至超乎人們的想象。1D推理判斷題。根據(jù)“because fear makes you do things that keep you alive.”可知D項正確。2A細(xì)節(jié)理解題。根據(jù)“If they sense that a hungry snake is about to attack，however，they can

29、hatch up to 2 days ahead of schedule.”和“Once tadpoles land in the water，hungry fish and other animals like to eat them，too.”可知，它們在孵化期間害怕蛇的攻擊，在水里害怕被其他動物吃掉。故選A項。3D主旨大意題。文章通過舉例說明害怕是一件好事。故選D項。4C篇章結(jié)構(gòu)題。根據(jù)“Some animals respond to fear in ways you might not expect.The first example is that the fear of being

30、 eaten can scare some frogs right out of their eggs.”可知，既然這是舉例，有了第一個例子，那么它的后面還會有例子。故選C項。(三)【要點(diǎn)綜述】本文論述了美國的環(huán)境保護(hù)局提出，為了人們的健康，要求各公司各企業(yè)采取措施，減少污染物的排放?？墒?，提議遭到了一些企業(yè)主的反對，他們認(rèn)為排污的設(shè)備和技術(shù)的投資太大，一些批評家也說在經(jīng)濟(jì)蕭條期要做到減少排污量很難。1B細(xì)節(jié)理解題。根據(jù)“They say investments required to produce cleaner air are too expensive and not scientif

31、ically justified.”可知減少污染的投資太大。故選B項。2D細(xì)節(jié)理解題。根據(jù)“Ms Jacksons proposalto reduce the permitted level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billionis sensible，no matter what industrys defenders may claim.”可知選D項。3A作者態(tài)度題。根據(jù)“As it is，about half the countries that monitor ozone levels are not yet in compliance with current standards，let alone the proposed standard.”可知，作者只是客觀地描述事實，所以A項正確。4C標(biāo)題歸納題。根據(jù)整篇短文的意思可知，作者在倡導(dǎo)減少污染，還人們美好的生活，故選C項。
