    Air pollution shortens human lives by more than a year, according to a new study from a team of leading environmental engineers and public health researchers. Better air quality could lead to a significant extension of lifespan(寿命) around the world.

It is the first time that data on air pollution and the lifespan has been studied together in order to check how air pollution affects overall life expectancy.

The researchers looked at outdoor air pollution from particulate matter (PM)(颗粒物) smaller than 2.5 microns. These particulates can enter deep into the lungs, and breathing PM 2.5 is associated with the increased risk of heart attacks, strokes and cancers. PM 2.5 pollution comes from power plants, cars and trucks, fires, agriculture and industrial emissions(排放物).

Led by Joshua Apte, the team used data from the Global Burden of Disease Study to measure PM 2.5 air pollution exposure and its consequences in 185 countries. They then quantified the national impact on life expectancy for each individual country as well as on a global scale.

“The fact that air pollution is a major global killer is already well­known,” said Apte. “And we all care about how long we can live. Here, we were able to systematically identify how air pollution shortens lives around the world. What we found is that air pollution has a very large effect on survival — on average about a year globally.”

In the context of other significant phenomena negatively affecting human survival rates, Apte said this is a big number. “For example, it’s considerably larger than the benefit in survival we might see if we found cures for both lung and breast cancer combined,” he said. “In countries like India and China, the benefit for elderly people of improving air quality would be especially large. For much of Asia, if air pollution were removed as a risk for death, 60­year­olds would have a 15 percent to 20 percent higher chance of living to age 85 or older.”

1.What do we know about PM 2.5?

A.It has a bad effect on human health. B.It will be controlled in the future.

C.It only comes from industrial emissions. D.It spreads to the world from Asian countries.

2.What did the researchers do to study how air pollution affects the lifespan?

A.They collected accurate information from all the Asian countries.

B.They employed the research data to calculate the effect.

C.They studied the disease and lifespan together time and time again.

D.They measured particulate matter much more carefully than before.

3.What can be inferred from the text?

A.The key to people living longer is good air quality.

B.People think air pollution is the most dangerous killer to them.

C.Apte will agree that people should take action to deal with air pollution.

D.Factories should decrease the production of cars to stop air pollution.

4.What is the best title for the text?

A.The Way Human Beings Enjoy a Longer Lifespan

B.The Importance of Getting Rid of Air Pollution

C.Asian People Are Suffering from Serious Air Pollution

D.Air Pollution Reduces the Lifespan by More than One Year

 

1.A 2.B 3.C 4.D 【解析】 本文是一篇说明文。研究表明,良好的空气质量有益于延长寿命,但是空气污染导致细颗粒物进入人体肺部,导致心脏病、中风、癌症的发病率升高,从而影响人的寿命。 1. 细节理解题。根据第三段中These particulates can enter deep into the lungs, and breathing PM 2.5 is associated with the increased risk of heart attacks, strokes and cancers.可知这些微粒可以进入肺部深处,吸入PM2.5会增加心脏病、中风和癌症的风险。由此可知,PM 2.5对人类健康有不良影响。故选A。 2. 细节理解题。根据第二段It is the first time that data on air pollution and the lifespan has been studied together in order to check how air pollution affects overall life expectancy.可知这是首次将空气污染和寿命数据一起研究,以检验空气污染如何影响总体预期寿命。由此可知,为了研究空气污染如何影响寿命,研究人员使用研究数据来计算效果。故选B。 3. 推理判断题。根据最后一段中“In countries like India and China, the benefit for elderly people of improving air quality would be especially large. For much of Asia, if air pollution were removed as a risk for death, 60­year­olds would have a 15 percent to 20 percent higher chance of living to age 85 or older.”可知“在印度和中国这样的国家,改善空气质量对老年人的好处会特别大。对于亚洲大部分地区来说,如果消除空气污染这一死亡风险,60岁的老人活到85岁或以上的机会将提高15%到20%。”由此可推知,Apte会同意人们应该采取行动来处理空气污染。故选C。 4. 主旨大意题。根据第一段中Air pollution shortens human lives by more than a year, according to a new study from a team of leading environmental engineers and public health researchers.可知一项由顶尖环境工程师和公共卫生研究人员组成的研究表明,空气污染会使人类寿命缩短一年多。结合文章主要说明了研究表明,良好的空气质量有益于延长寿命,但是空气污染导致细颗粒物进入人体肺部,导致心脏病、中风、癌症的发病率升高,从而影响人的寿命。故D选项“空气污染使寿命缩短一年以上”最符合文章标题。故选D。

    I realized something this morning. I have been writing now for 34 years. It all started when I was just 18 years old. As a boy I had read literally(毫不夸张地)hundreds of books. I had a thirst for knowledge that seemingly could never fade. Then suddenly I found I had something I wanted to share. I tried to ignore it, but as any writer will tell you once the ideas awaken inside of you they won't leave you alone until you write them down. I didn't have a computer, word processor, or even a typewriter. Still, I grabbed a pen and lined notebook paper and wrote everything that was burning inside of me.

When I was done I didn't know how to share it. There was no internet back then, no smart phones, and no social media. I sought out the editor of my local county newspaper and asked him to print what I had written. He was a good man full of both wisdom and kindness. He not only printed my first story but agreed to publish anything else I was willing to write. I continued to write new articles each week and shared them first with other local papers and later online as well. Years later at the urging of my readers I even self-published two collections of my stories in book form.

Through my writing I slowly became more than I was. In my writings I encountered my highest self. In my writings I discovered the goodness and light that lies in us all. In my writings I found great love and joy and encouraged others to choose love and joy as well. I also found that we all are writers whether we put pen to paper or not. With every choice we make, with every thought we hold, and with everything we do we are writing our own life story.

Lance Wubbels once wrote: "I hope you realize your life is truly your life. It belongs to you. It is your story to write with love. Day by day, line by line, write it well."

1.As a boy, when the author found he had something to share, ________.

2.How did the author begin his writing career?

A.He was hired as a newspaper editor.

B.He put his stories online by himself.

C.He self-published two books.

D.He was helped by a local newspaper editor.

3.What does the author think of writing?

A.Writing takes practice and efforts.

B.Writing can benefit oneself and others.

C.Writing helps people tell right from wrong.

D.Only with a pen can one write his life story.

4.Which of the following can be the best title for the text?

A.A Way to be a Writer

B.A Way to Share Ideas

C.Living is Writing

D.Writing is the Source of Love

阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。

Robert and Henry were two friends in the same class. They always played together and went home together. One day Robert and Henry were going home from school, when, on turning a corner, Robert cried out, “A fight! Let’s go and see!”

“No,” said Henry. “Let us go quietly home and not meddle with(插手) this quarrel. We have nothing to do with it and may get into mischief(trouble). Also our parents are expecting to have dinner with us together at home and I don’t want them to worry about me. ”

“You are a coward, and afraid to go,” said Robert, and off he ran. Henry went straight home, and in the afternoon went to school as usual.

But Robert had told all the boys that Henry was a coward, and they laughed at him a great deal. From then on, they looked down upon Henry and didn’t want to play with him together.

Henry was sad but he wasn’t angry with Robert for his rude behavior, because he learned that true courage is shown most in bearing misunderstanding when it was not deserved, and that he ought to be afraid of nothing but doing wrong. Thus, he just ignored the other boys’ laughter and continued to go to school and study as well. However, Robert didn’t invite Henry to go home with him anymore. Instead, he had some other boys who also thought Henry was a coward. Every day after school, they didn’t go home directly but went to the river or somewhere to play games and had a lot of fun.

A few days later, Robert was bathing with his new friends in a river, and got out of his depth. He struggled, and screamed for help, but all in vain. The boys who had called Henry a coward got out of the water as fast as they could, but they did not even try to help him.
