六.阅读理解

Like distance runners on a measured course,all of us will move through time in a roughly predictable pattern.

In the first stage of our lives,we develop and grow,reaching toward the top of physical vitality(energy).

After we grow up,however,the body begins a process of gradually wearing out.

A new awareness of physical fitness may help lengthen our years of health and vitality,yet nothing we do will work to stop the unavoidable force of aging.

Most of the changes of aging take place deep inside the body. The lungs become less able to take in oxygen. Powerful muscles gradually lose their strength. The heart loses power and pumps less blood. Bones grow easier to break.

Finally,we meet a stress,a stress that is greater than our physical resistance. Often it is only a minor accident or chance infection(a disease caused by virus),but this time,it brings life to an end.

In 1932,a classic experiment nearly doubled the lifetime of rats,simply by cutting back the calories (unit for measuring the energy value of food)in their diet. The reason for the effect was then unknown.

Today,at the university of California at Berkley,Dr. Paul Seagle has also greatly lengthened the normal lifetime of rats. The result was achieved through a special protein(蛋白质)limited diet,which had a great effect on the chemistry of the brain. Seagle showed that within the brain,specific chemicals control many of the signals that influence aging. By changing that chemical balance,the clock of aging can be reset.

For the first time,the mystery(something that is difficult to understand or to explain)of why our age is being seriously challenged. Scientists in many fields are now making striking and far reaching discoveries.

An average lifetime lasts 75 years,yet in each of us lies a potential for a longer life. If we could keep the vitality and resistance to disease that we have at age twenty,we would live for 80 years.

1.What does the underlined word“it”refer to?

A.Physical vitality. B.Stress. C.Aging. D.Physical resistance. 2.The author believes the following EXCEPT that ________.

A.human's life pattern is predictable

B.physical fitness can't stop the force of aging

C.human's lifetime will last longer than 75 years

D.all of the changes of aging take place deep inside the body

3.How did Dr. Paul Seagle lengthen the lifetime of rats in his experiment?

A.By limiting the protein in their diet. B.By cutting the calories in their diet.

C.By resetting their clock of aging. D.By keeping their physical fitness.

4.What is probably the best title for the article?

A.Two Great Experiments B.The Mystery of Human Life

C.Ways to Lengthen Human Life D.The Breakthrough in the Study of Aging

Good morning, everyone,

I’m Li Hua from Xingguang Middle School. The topic of my speech is “Let’s Ride Bicycles”.

As is known to all, with the improvement of people’s living standards, cars have become a popular means of transport, bringing great convenience to our life. However, they have also caused some problems such as air pollution and traffic jams.

How can we solve the problems then? As far as I’m concerned, riding bicycles is a good solution. For one thing, bicycles don’t need any petrol and they are energy-saving. For another, bicyles are environmentally friendly because they won’t give off waste gas. What’s more, riding bicycles is a good way ofr us to exercise and it is beneficial to our health.

Therefore, let’s take the responsibility to build up a low carbon city by riding bicycles. Come on and join us! Thank you!

综英5 Unit4 课后练习参考答案

Unit 4 Part I Listening Task Script for the recording: You may recall from Unit One, the author Eudora Welty telling us how she, in her early childhood, developed a love for reading under the influence of her parents. Perhaps you'd like to know what her teachers were like. Well, let's listen to what she has to say about them: Every school week, visiting teachers came on their days for special lessons. On Mondays, the singing teacher blew into the room fresh from the early outdoors, singing in her high soprano "How do you do?" to do-mi-sol-do, and we responded in chorus from our desks, "I'm ve-ry well", to do-sol-mi-do. Miss Johnson taught us rounds —"Row row row your boat gently down the stream", — and "Little Sir Echo," with half the room singing the words and the other half being the echo, a competition. She was from the North, and she was the one who wanted us all to stop the Christmas carols and see snow. The snow falling that morning outside the window was the first most of us had ever seen, and Miss Johnson threw up the window and held out wide her own black Cape and caught flakes on it and ran, as fast as she could go, up and down the ais1es to show us the real thing before it melted. Thursday was Miss Eyrich and Miss Eyrich was Thursday. She came to give us physical training. She wanted no time on nonsense. Without greeting, we were marched straight outside and summarily divided into teams (no choosing sides), put on the mark, and ordered to get set for a relay race. Miss Eyrich cracked out "Go!" Dread rose in my throat. My head swam. Here was my turn, nearly upon me. (Wait, have I been touched —was that slap the touch? Go on! Do I go on without our passing a word? What word? Now am I racing too fast to turn around? Now I'm nearly home, but where is the hand waiting for mine to touch? Am I too late? Have I lost the whole race for our side?) I lost the relay race for our side before I started, through living ahead of myself, dreading to make my start, feeling too late prematurely, and standing transfixed by emergency, trying to think of a password. Thursdays still can make me hear Miss Eyrich's voice. "On your mark —get set — go!" V ery composedly and very slowly, the art teacher, who visited each room on Fridays, paced the aisle and looked down over your shoulder at what you were drawing for her. This was Miss Ascher. Coming from behind you, her deep, resonant voice reached you without being a word at all, but a sort of purr. It was much the sound given out by our family doctor when he read the thermometer and found you were running a slight fever, " Um-hm. Um-hm." Both alike, they let you go right ahead with it. After Listening 1.On Mondays, Miss Johnson, our singing teacher, would blow into the room, singing in her high soprano "How do you do?" to do-mi-sol-do, and we students would respond in chorus from ouir desks, "I'm very well", to do-sol-mi-do. 2.Miss Eyrich gave us physical training on Thursdays. She wanted no time on nonsense. Without greeting, she ordered us to march straight outside and get set for a relay race. 3.In a very composed and slow manner, the art teacher Miss Ascher would pace the aisle and

Unit4 无子女家庭:违背十万年来的繁衍规律 课文翻译: 二十好几的凯茜、韦恩夫妇结婚已有五年之久,没有孩子。上次凯茜娘家有人问:“你们打算什么时候要孩子,组成一个家庭呢?”她答道:“我们已经是个家庭啦!” 凯茜与韦恩属于决定不要孩子的年轻已婚夫妇群体,其人数正在日益增长。最近一项调查显示在过去的五年中,年龄在25至29岁之间妇女不愿生养的百分比几乎翻了一番,在18至24岁的已婚妇女中几乎增至三倍。在这个似乎大胆反抗生物性和社会性的决定后面隐藏着什么原因呢? 或许最能公开坦陈心曲的无子女夫妇是《婴儿陷阱》一书的作者:埃伦,派克,其夫威廉,一位广告总经理兼全国不生养夫妇协会主席。派克夫妇认为他们和协会均无意反对生儿育女,不过是反对不管人们是否愿意和需要孩子就迫使人们传宗接代的社会压力。 “这是一种生活方式的选择,”埃伦说,“我们选择自由和自愿,清净和闲暇。这也是一个朝哪个方向付出努力的问题——在你自己的小家庭之内或在一个大的社团之中。这一代人面临有关地球生命延续的严重问题以及生命质量的问题。我们的孙辈也许将购票去观赏最后一批红杉或排队去获取氧气配给。有人抱怨在回到有五个孩子的家途中被交通堵塞困住好几个小时,但是他们不能将孩子与交通堵塞联系起来。在一个受到人口过剩一系列后果威胁的世界上,我们正在参与一项事业使膝下无子的生活模式为社会所接受并受世人尊重。太多的孩子作为一种文化强制的后果而呱呱坠地,离婚和虐待儿童的相关统计充分揭露了这一结果。” 埃伦的丈夫补充说:“每位朋友、亲戚、同事不停地给你施加压力,劝你要孩子,说什么‘发现你生活中失去的东西’。好多好多人很晚才发现,所谓他们失去的东西其实是他们完全不适合做的事情。” 埃伦还说:“从抱第一个洋娃娃开始,大到欣赏电视肥皂剧,成年后参加鸡尾酒会,无形之中,总有一种压力要你为人父母。但是让我们来看看养育失败的比率吧,或许天下父母应该视为像当医生一样的专门职业。有些人擅长此道,他们应当生养孩子;有些人一窍不通,他们应该认为他们还有其他的选择。” 专业观察家同意这一看法:很多人生养孩子没有正当的理由,有时候则完全没有理由。男人常常稀里糊涂就当上了父亲,根本就没有作出审慎的选择;对许多妇女来说,怀孕能够成为一种方式来逃避不可解决的冲突,譬如,迅速获得名分,或改进自己的不良形象,以及满足童年时代未曾得到的关注和关爱的需要。 我与许多人类行为领域的专家交谈,探讨为什么那么多年轻夫妇决定不要孩子,他们的看法也是众说纷纭。一位家庭治疗专家把不要孩子的决定描写为“对当今世界形势基本的本能反应”,暗示像动物群居本能那样的东西正在起作用,来应对人口过剩、城市拥挤、环境污染与核战争危险。群居本能促使妇女感到繁殖人口有违心愿,并指引她们去寻找在家庭生活之外实现自我价值的新方式。 不止一位精神病医生暗示,凡是不愿生育的人有都自恋癖——觉得自己心甘情愿迫不得已,为照顾别人与受人照顾这个互相对立的内心冲突自圆其说。有位精神病医生说:“这些人不能容忍照顾孩子的想法,他们没有多余的爱分享给孩子,”并补充道,“你们这是对亘古以来人类繁衍生生不息的离经叛道。”他的另一位同事插话说:“情有可原嘛,我们谁不想为我们的欠缺找理由? 且不论他
