手惰市安逸阳光实验学校高考英语二轮专题复习精品阅读理解部分之限时训练（四）阅读理解A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin. Amphibians(两栖动物), animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo. Now the same oxygen sensors found in frog skins and in the lungs of mammals have unexpectedly been discovered in the skin of mice.“No one had ever looked,” explained Randall Johnson, a biologist researcher.Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.“We have no reason to think that they are not in the skin of people too,” Johnson said.These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1 a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained. The scientists detailed their findings in the April 18 issue of the journal Cell.64. Which of the following statements is TRUE according to the passage?A. Johnson believes that oxygen sensors also exist in human skin.B. People have to surf the Internet to read detailed findings.C. It has been proved that these findings help treat lung diseasesD. It has long been expected oxygen sensors exist in mice’s skin.65. One of the functions of the molecules mentioned above is _______.A. carrying oxygen around the bodyB.improving athletes’ performanceC. detectingoxygenD. increasing level of oxygen66. What is Johnson’s attitude to the application of the findings to the athletes’ training?A. NegativeB. DoubtingC.Positive D. Hesitating67. The best title of the passage may be _______.A. Great Findings Benefit Athletes A LotB. Frogs And Mice Are Distant RelativesC. First Known Animal Breathes Through SkinD. Humans Might Sense Oxygen Through Skin完形填空（共20小题；每小题1分，满分20分）A farmer had some puppies (小狗) he needed to sell.

People still move for these reasons, but new reasons for human migration are arising, such as job relocation(重新安置) and overpopulation. Three million migrants are moving from poor countries to wealthier ones each year, and increasingly, their destination is a neighboring country in developing parts of the world. People are moving within the developing world for the same reasons as they migrate to wealthier nations. People from poor countries are going to less poor countries, fleeing wars and conflicts. They are also responding to population pressures because some countries are densely populated, and they often have high population growth. Those people need to go somewhere else.There are three main reasons why people move. The basic categories and percentages are as follows, according to the Current Population Surveys (CPS):Family-related reasons account for 26.3%, including changes in marital （婚姻的） status, establishing a household and other family reasons; work-related reasons 16.2%, including job transfer, retirement, and other job-related reasons; housing-related reasons 51.6%, including new and better houses, better neighborhood, cheaper housing and other housing reasons; the remaining 5.9% of other reasons are attending college, the change of climate and health reasons.Americans have been migrating south and west for decades in search of better job opportunities and warmer climates. They have also been moving to places a little far from cities, in search of bigger yards and houses, lower crime rates and better schools. In 1950, nearly a fifth of the population lived in the nation’s 20 largest cities. In 2006, it was about one in ten. That’s why many American people say, “Big Cities Shrink as People Move South, West.”Between March 2005 and March 2007, 73.4 million Americans moved. Fifty-six percent of these moves were within the same country. Twenty percent were between counties but in the same state. Nineteen percent were moves to a different state. Some families even went abroad. Title: People on the 71参考答案阅读理解64----67 ACCD完形填空36－40 CBADB; 41－45 ABCCC; 46－50 DBADA; 51-55 DDAAB任务型阅读：71. move, 72. history, 73. increasing, 74.richer/wealthier, 75.

第4课《论语》十二章、大学之道、人皆有不忍人之心一、立足文本（一）阅读下面文字，回答问题。

孟子曰：“人皆有不忍人之心。

先王有不忍人之心，斯有不忍人之政矣。

以不忍人之心，行不忍人之政，治天下可运之掌上。

所以谓人皆有不忍人之心者，今人乍见孺子将入于井，皆有怵惕恻隐之心，——非所以内交于孺子之父母也，非所以要誉于乡党朋友也，非恶其声而然也。

由是观之，无恻隐之心，非人也；无羞恶之心，非人也；无辞让之心，非人也；无是非之心，非人也。

恻隐之心，仁之端也；羞恶之心，义之端也；辞让之心，礼之端也；是非之心，智之端也。

人之有是四端也，犹其有四体也。

有是四端而自谓不能者，自贼者也；谓其君不能者，贼其君者也。

凡有四端于我者，知皆扩而充之矣，若火之始然，泉之始达。

苟能充之，足以保四海；苟不充之，不足以事父母。

”1．下列加横线的词的解释，不正确的一项是( )A．皆有怵惕恻隐之心怵惕：恐惧。

B．非所以内交于孺子之父母也内：同“纳”，结交。

C．非所以要誉于乡党朋友也要：通“徼”，求取。

D．若火之始然，泉之始达然：……的样子。

2．下列句中加横线“之”的意义和用法，与例句相同的一项是( )例句:人之有是四端也A．若火之始然,泉之始达B．知皆扩而充之矣C．人皆有不忍人之心D．治天下可运之掌上【答案】A【解析】A项与例句都是结构助词,用在主谓之间,取消句子独立性。

B项,代词,代前文的“四端”。

C项,结构助词,的。

D项,代词,代“治天下”。

3．下列对原文有关内容的概括和分析，不正确的一项是（）A．孟子从人性的前提推导政治，从人人都有“不忍人之心”的仁心推导仁政，突出仁政应该是天经地义的。

B．孟子提出的“人皆有不忍人之心”是对孔子关于“人性”思想的进一步发展。

尤其在此基础上提出的“仁义礼智”，更是成了中国古代哲学中“性善论”的理论基础和支柱。

C．孟子指出“不忍人之心”是人生而固有的，承认“仁义礼智”是人的天性里固有的，体现了孟子朴素的唯物主义思想。
