课时分层作业(七)　[高考题型练习提能力]Ⅰ.阅读理解ALive in the City—Many of us yearn to live in the country，so we can be closer to nature and enjoy peace and quiet.However，when we do this there are less wild areas for wildlife.We need to develop a new environmental theory，which encourages people to stay in the cities.We have to make cities more livable and leave the remaining wild areas for the wildlife.Support Strict Zoning—Land use zoning(土地用途分区管制) is one of the few tools the government can use to protect wetlands，natural areas and environmental corridors.Unfortunately，such zoning is often opposed by powerful land developers or political forces.It's important for citizens to show support for zoning to offset these negative pressures.Support Organizations Preserving Rare Properties—Several groups specialize in buying and keeping pieces of important wildlife habitat which are threatened with development.Create Habitat in Your Backyard—You can make your own backyard habitat for wildlife by planting native plants，putting nest boxes in the trees and so on.Save Energy—We must work together to use less energy.This is important to stop climate change and global warming.Saving energy also reduces direct habitat losses and air and water pollution，all of which threaten wildlife.Limit Your Family Size—Each person requires space and natural resources to live.The human population is rapidly rising to levels which make it difficult to provide enough resources for humans while maintaining a healthy environment for wildlife.If each couple limited themselves to no more than 2 children，the world's population would stabilize(稳定) and be able to support everyone without conflict or suffering.Get Involved and Talk to Law Makers—Many of our laws are not helpful for preserving wildlife habitat or saving energy，and some policies actually reward large energy users.Citizens need to contact their law makers and ask for better policies.【语篇解读】　本文主要介绍的是我们普通人可以做哪些事情来保护野生动物。1．What would be the best title for this passage?A．Where Should We Live in the Future?B．How to Protect Our Environment?C．Why Should We Save Energy?D．What Can We Do to Help Wildlife?D　[标题归纳题。本文中的几项内容都是关于我们普通人可以做哪些事情保护野生动物的。]2．The underlined word “yearn” in Paragraph 1 probably means ．A．hope　　　　　　　 B．fearC．hate D．failA　[词义猜测题。根据后半句的内容，居住在乡下能使人们亲近大自然，享受平和安静的生活，所以人们希望到乡下居住。]3．Which of the following actions will NOT destroy the homes of wildlife?A．Building houses in the country.B．Putting nest boxes in the backyard.C．Releasing dirty water into a river.D．Couples having many children.B　[细节理解题。根据文章内容可知居住在乡下、污染水资源和增加人口都会威胁到野生动物的家园，而人工放置鸟巢是保护野生动物的一种方式，所以选B项。]BMore than two thirds of the world's polar bears will be wiped out by 2050，according to a shocking new study.By then，scientists say，global warming will have melted 42 percent of the Arctic sea ice.By 2100，only a very few of these important creatures will be left.The report has been produced by the US Geological Survey.The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food.Without enough ice，polar bears would be forced to go onto the land，where they are poorly skilled hunters，and would be unlikely to adapt to the life on the land in time.Experts say few little bears would survive and the stress could make many females unable to get pregnant.The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab，using computer models.Some team members fear the result is even worse for the bears than what their report says.They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting.Satellite observations have showed that the ice has decreased to an all­time low.However，not everyone in the scientific community believes that global warming is happening on such an alarming scale.Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads.At least ten international companies offer bear­hunting trips.【语篇解读】　本文说的是由于全球变暖，北极熊有可能在这个世纪末就要灭绝了。4．What do we know about Dirk Kempthorne according to the passage?A．He is an animal scientist.B．He is a protector of animals working for the US government.C．He was asked to put polar bears on the US endangered species list.D．He offered to put polar bears on the endangered species list.C　[细节理解题。根据第二段第二句中的“...US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.”可知C正确。]5．Why will polar bears die out if there is not enough sea ice?A．Because polar bears can't catch enough food without ice.B．Because polar bears eat ice when they feel thirsty.C．Because polar bears will be easily found by hunters without ice.D．Because most female bears are used to giving birth under ice.A　[推理判断题。由文章第三段第一句“Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food.”可知A正确。]6．After a six­month study，some scientists fear that ．A．there is something wrong with their computersB．polar bears will disappear even faster than they ever expectedC．their computer models are not as accurate as they expectedD．global warming will destroy everything in the ArcticB　[细节理解题。由文章第四段第二句“Some team members fear the result is even worse for the bears than what their report says.”可知B正确。]7．What is this passage mainly about?A．Global warming makes the whole world different.B．Human beings are responsible for the endangered species.C．Most of the polar bears will be wiped out by the end of this century.D．Scientists have found that most animals in the Arctic will die out by the end of this century.C　[主旨大意题。本文第一段点明了主题：北极熊有可能在这个世纪末就要灭绝了。]Ⅱ.阅读七选五Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways.The WHO released five simple rules for preparing food in a safe way. 1Key 1 ：Keep clean.The first key tells about the importance of washing.People should wash their hands often—before touching food，while they are preparing food，and any time after they go to the toilet.People should wash all surfaces and equipment used for preparing food. 2Key 2: 3People should separate raw，or uncooked foods from foods that are already cooked and foods that will not be cooked.People should store raw meat，chicken，and fish in containers，or in separate areas.Raw foods should not touch prepared foods.Key 3 ：Cook completely.People should cook eggs and meat，like birds，seafood，and animals，especially carefully.These foods may carry more micro­organisms than other foods.Food like soup must be boiled for at least a minute to make it be cooked completely.It is also important that people re­heat cooked food completely.Key 4：Keep food at safe temperatures.When people are finished with eating，they should keep the left food in a refrigerator below 5℃ and shouldn't store it for too long.At room temperature，about 20℃，the amount of micro­organisms can increase very quickly. 4 They cannot grow as quickly in a very hot or very cold environment.Key 5：Use safe water and raw materials.5 Damaged or old food may develop harmful chemicals as it gets older.A．Separate raw and cooked foods.B．Eat cooked food immediately while it is still hot.C．They call these rules the “Five Keys to Safer Food”．D．People should use safe water and choose fresh foods.E．Keeping everything clean helps people to avoid micro­organisms.F．People should also protect cooking areas and food from insects and animals.G．But temperatures above 60℃ or below 5% control the growth of micro­organisms.【语篇解读】　食品安全问题是一个全世界性的问题。不同地方的人用不同的方式准备食物，WHO发布了用安全方式准备食物的五项原则。1．C　[第一段中的The WHO released five simple rules for preparing food in a safe way.是提示句。C项中的these rules与空前的five simple rules 相对应。另外，C项可以引起下文。故选C项。]2．E　[此部分的小标题为Key 1：Keep clean.E项中的clean与小标题的内容相对应。另外，E项为保持干净的好处，与该段内容相符。故选E项。]3．A　[此部分讲的是要把生的食物和熟的食物分开放置。关键词为raw，cooked。A项意为“把生的食物和熟的食物分开”。故选A项。]4．G　[此处讲的是微生物的生存环境。空前讲的是微生物快速繁殖所需的温度。所以此空应该是微生物在什么温度下无法快速繁殖。故选G项。]5．D　[D项为本段小标题的进一步说明。关键信息为safe water。故选D项。]Ⅲ.语法填空Tuan was a farmer.For decades，he 1.
