Whenever I hear a recording of John Denv...

    Whenever I hear a recording of John Denver singing “Sunshine on My Shoulders” I find myself smiling, drawn to a love of the sun and the outdoors I’ve had for years as a Michigan native. Walking barefoot to the lake, playing without shirts in the sunlight, and breathing fresh air feel good. As a doctor I can tell you they are also good for your heart.

Studies have found higher rates of high blood pressure among people with the lowest sun exposure. One reason may be due to nitric oxide (一氧化氮), a gas whose function is activated when your skin is exposed to the sun’s rays. It reduces both heart attack and stroke risks. Vitamin D, which sunlight helps your body produce, is also linked to better health. So walk outdoors for 15 to 30 minutes daily.

In Japan, walking through forests to keep healthy has become a popular practice. Apparently they want to enjoy the fresh air. But research on 280 volunteers found that people had a reduced heart rate, and lower blood pressure when they walked through a forest than when they spent time in an urban area.

One of the consequences of modern society is that rarely is our body in direct contact with the ground. The earth has an electrical current. Direct contact with it may be stabilizing force for good health. Although “earthing” or “grounding” is considered alternative by mainstream medicine, research shows that the practice seems to be able to reduce heart disease risks.

So, walk around barefoot wherever possible, let your backyard grass tickle your feet, and dig your toes into sandy beaches.

1.The first paragraph is meant to ________.

A.show the author likes the song very much

B.put forward the argument of the passage

C.suggest that the author loves nature crazily

D.indicate the author is a Michigan native

2.Sunbathing is good for heart because _______.

A.the sun’s rays make nitric oxide work

B.sunlight can help people keep warm

C.the sun’s rays can help replace vitamin D

D.vitamin D reduces blood circulation

3.It’s believed that walking through forests can ________.

A.make people popular B.help breathe in fresh air

C.reduce blood pressure D.help escape noisy cities

4.The best title of the passage should be ________.

A.Nitric Oxide Has Magic Functions

B.Walking Barefoot Builds the Body

C.Sunbathing is Good for Health

D.Outdoor Activities Benefit the Heart

 

1.B 2.A 3.C 4.D 【解析】 本文是一篇议论文。作者通过叙述自己的经历、感受和一些研究发现,告诉人们户外活动有益于心脏。 1.推理判断题。根据第一段Whenever I hear a recording of John Denver singing “Sunshine on My Shoulders”, I find myself smiling, drawn to a love of the sun and the outdoors I’ve had for years as a Michigan native. Walking barefoot to the lake, playing without shirts in the sunlight, and breathing fresh air feel good. As a doctor I can tell you they are also good for your heart.可知,每当我听到约翰·丹佛(John Denver)演唱《阳光照在我肩上》(Sunshine on My Shoulders)的录音时,我就会情不自禁地微笑起来。作为密歇根本地人,我多年来一直热爱阳光和户外活动。光着脚在湖边散步,在阳光下不穿衣服玩耍,呼吸新鲜空气的感觉很好。作为一名医生,我可以告诉你,它们对你的心脏也有好处。结合下文内容,由此判断出作者写这段的目的是为了提出文章的论点,即该段最后一句中的“they are also good for your heart”。故选B项。 2.细节理解题。根据第二段One reason may be due to nitric oxide (一氧化氮), a gas whose function is activated when your skin is exposed to the sun’s rays. It reduces both heart attack and stroke risks.可知,原因之一可能是一氧化氮,当你的皮肤暴露在阳光下,一氧化氮的功能就会被激活。它可以降低心脏病发作和中风的风险。由此可知,日光浴对心脏有好处是因为阳光能激活一氧化氮的功能。故选A项。 3.细节理解题。根据第三段第三句But research on 280 volunteers found that people had a reduced heart rate, and lower blood pressure when they walked through a forest than when they spent time in an urban area.”可知,但对280名志愿者的研究发现,当人们在森林中行走时,他们的心率和血压都比在城市中行走时要低。所以人们普遍认为穿过森林可以降低血压。故选C项。 4.主旨大意题。根据全文内容,尤其是第一段中的“As a doctor I can tell you they are also good for your heart.”户外活动对你的心脏也有好。及最后一段“So, walk around barefoot wherever possible, let your backyard grass tickle your feet, and dig your toes into sandy beaches.”所以,尽可能的光着脚到处走,让你后院的草挠你的脚,把你的脚趾伸进沙滩。可知,这篇文章的最佳标题是“户外活动有益于心脏”。故选D项。

    One stride at a time, Tom Panek and his guide dog, Gus, inch closer to their goal. The two have been training in local parks for more than three years with the hopes of competing in an official long­distance race. It’s never been done before. “I’ve been running my whole life. I ran on my cross­country team in high school, and I ran as a young adult,” Panek said. He lost his sight 25 years ago. “When I lost my sight I was too scared to run,” Panek said.

As he adjusted to his blindness, he began running with a human guide, but it wasn’t the same. “Although many people run with running clubs, at the end of the day you’re running your own race. And when you’re tied to another person, it’s no longer your own race. The independence isn’t quite there,” Panek said.

Two years ago, Panek became the CEO of Guiding Eyes for the Blind. The idea of a running guide program was first suggested by Richard Hunter, who was blind and looking to get back in to running.

“Richard shouted out, ‘I’m really curious, have you ever trained a guide dog to run’ And I said, ‘I don’t know. It hasn’t been done,’” Panek said.

A few months and intense training sessions later, the running guide program was born. Panek and a small team helped train Klinger, a German shepherd, to aid Hunter with running.

He formed a team of experts to train a small group of dogs to run long distances. The dogs begin their training at 18 months old. It’s an exclusive club. Out of 165 graduate dogs, only about 12 are considered race ready.

The team’s final test would be a five­mile race through New York’s Central Park just one week before the New York City Marathon. It was Panek’s and Gus’s first competitive race. Before the race, Panek was overcome with emotion, wiping away his tears of appreciation to the dog who gave him his independence back.

“And crossing that finish line, you know it was a momentous (关键的) occasion for me,” Panek said.

1.How did Panek think of running with a human guide?

A.Inspiring. B.Challenging.

C.Rewarding. D.Disappointing.

2.What was Hunter curious about?

A.Training a dog guide to run. B.Getting back to run as a blind man.

C.Starting a running guide program. D.Running with a human guide.

3.Which of the following is mentioned in the article?

A.Dogs are reluctant to run long distances.

B.Few dogs are qualified to guide in running.

C.Some dogs are born to be a guide in races.

D.Dogs need to be trained for 18 months.

4.What does particular significance the final test have to Panek?

A.He won a big prize with Gus’ help.

B.His guide dog was treated well in the race.

C.He got his independence once again.

D.He ran to the finishing line without stopping.
