1 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.

According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.

To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.

“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.

Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.

It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

1. What did scientists from German universities recently discover?

A．Working out is a highly effective way to treat depression.

B．The runner’s high could be caused by endocannabinoids.

C．Endorphins may contribute to one’s high spirits after running.

D．The level of endorphins and endocannabinoids could affect one’s mood.

2. Why did the scientists give mice drugs in their experiment?

A．To find what reduces the runner’s high symptoms.

B．To see the specific symptoms of the runner’s high.

C．To identify what is responsible for the runner’s high.

D．To test what influences the level of endocannabinoids released.

2 . By now, most people know they should be eating more vegetables. But are there ways to get more from the vegetables you already eat? A research shows that when it comes to vegetables, it’s not only how much we eat, but also how we prepare them, that decides the vitamins and other nutrients that enter our body.

Many studies show that people who eat lots of vegetables have less heart disease, and eye problems and even cancer. But raw vegetables are not always best. The researchers found that 198 Germans who eat raw food were short of lycopene, the matter found in tomatoes and other red vegetables. “There is an idea that raw foods are always going to be better,” says Steven K. Clinton, a professor at Ohi o State University. “For fruits and vegetables, sometimes a little bit of cooking can be helpful.”

A number of factors decide how the vegetables do good to people’s health before they reach the table, including where and how they were grown and stored before being bought. No single cooking way is best. Some nutrients are easily lost in cooking if they are cooked in different ways.

Vitamins C and B are often lost. In January, another report said that boiling was better for carrots than frying or serving them raw. Frying was the worst way to cook.

What cooked with the vegetables can also be important? When the vegetables were cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them. Putting on some other things that make it taste better—a little salt—can make the food taste better.

A．the place where the vegetables are grown

A．It’s better to cook vegetables with fat

B．the more fat in the cooking, the fewer vegetables people will eat

C．It’s better to cook the vegetables without salt

D．the fat will increase the nutrition of the vegetables

3 . “Just sign here, sir,” the deliveryman said as he handed Oscar Reyna a package.

The package consisted of a long, narrow box ____ wrapped in brown paper. ____ the box, Oscar saw an umbrella inside—a very old one with a beautifully carved wooden handle. ____ he had not seen it in more than 20 years, he recognised it immediately.

“Why, yes! It’s mine,” replied Mrs. O’Brien with a ____ smile and shining eyes. “It was given to me by my father years ago. Thank you so much for returning it. May I offer you a reward for your ____?”

“No, ma’am,” he said. “My grandmother says that a good deed is its own reward.”

“Well, that’s ____ what my father used to say. What is your name, young man?”

Years later Oscar was staring at the finely carved handle of the umbrella as he remembered Mrs. O’Brien. It was in perfect condition, considering how ____ it was. Why had it arrived here today?

7 . Getting sick is a common part of people’s lives. But their attitudes toward being sick and hospital visits vary from country to country. This difference hasn’t been more obvious since the start of the novel coronavirus epidemic — when a great number of people are falling ill all at the same time.

The conditions in the US are getting worse quickly, which is largely due to the fact that there’s no universal health-care system. According to the 2019 US Census, 28 million people are not covered or do not have adequate health insurance, meaning that they would probably avoid getting tested for the virus, for fear of the cost of being hospitalized.

‘‘There is a strong financial reason to hide symptoms, to try to keep working and caring for children, and thus, they’re spreading the virus … simply because they have no other choice.” wrote reporter James Hamblin on The Atlantic.

Germany, on the contrary, has one of the world’s best-developed public healthcare systems that covers every citizen. People in Germany — who have ‘‘high levels of job security’’, according to the Los Angeles Times — are also more likely to follow the separation measures and stay at home without having to worry about losing their jobs.

Japan also has universal public health-care, but it brings another kind of problem: People tend to seek more medical care than necessary. According to Yusuke Tsugawa, a physician at Harvard University, Japan has three times more outpatient (门诊) visits than in the US, and patients also stay in hospital for three times longer than in the US. This often wastes medical resources, which are even more critical and precious during a global pandemic.

‘‘It isn’t good to do tests just to ease public anxiety,” Kentaro Iwata, an infectious disease expert at Kobe University, Japan, told Reuters. ‘‘If they test everyone with light symptoms, the medical system will break down.”

Indeed, a country’s healthcare system is the key to keeping its people safe - it’s also the key to whether a country can survive a crisis like the novel coronavirus pandemic.

1. Why are the conditions in the US worsening rapidly?

A．All people there avoid getting tested.

B．Most people there don’t have health insurance.

C．Most people there can’t afford being hospitalized.

D．All people there are not covered by health-care system.

2. According to James Hamblin, what makes people in US try to hide their illness?

A．They choose to do so.	B．They don’t want to work alone.
C．They are concerned about money.	D．They want to stay with their children.

3. What is the problem in Japan?

A．They have too many outpatient visits.

B．They waste too much time on unnecessary testing.

C．They spend too much money on public health-care.

D．They don’t make the best use of medical resources.

8 . A fat man with a camera around his neck and a bottle of sunscreen cream sticking out of his bag, he really did look like a tourist. He sat on the terrace (平台), sipping lemonade and pretending to look at a tourism brochure. His sunglasses masked his eyes, but I knew he wasn't looking at the brochure: he hadn't turned a page for the last ten minutes. As I brought him his dishes, he coughed up a "thank you" and looked at me briefly I tried not to stare at the tiny scar across his left eyebrow.

I walked back inside with my empty tray, shaking my head. He looked familiar, but I couldn't quite place him. Then it hit me. The car accident. The mysterious stranger who helped me out of my crashed car, just before it exploded. I rushed back to his table. He was gone.

I moved his saucer and found his tip, along with a card: I am deeply grateful to you. The night of your car accident, I was on my way to rob a jewelry store. Saving your life brought things back in a right way. I now live an honest life, thanks to you. God bless you! Mr. D.

I shivered (震颤). The night of my car accident, I was heading for an interview in an illegal dance club. Seeing human kindness through his heroic gesture (英雄姿态) turned my life around and brought faith back into my life. I unfolded the tip he left. Among the singles was a grand (一千块) with a pen mark underlining "In God We Trust. "I said a silent prayer for him and got back to work, smiling.

1. Why did the fat man look like a tourist?

A．Because he doesn't look like a native citizen.

B．Because he ordered strange food and drinks

C．Because he used money not the same as the locals.

D．Because he carried what tourists usually have on.

2. How did the writer knew the man didn't read the brochure?

A．The page remained unturned.	B．He was drinking all the time.
C．He sat still with his sunglasses.	D．He was staring at the writer.

3. What can we infer from the last paragraph?

A．The man became a rich man year later.

B．The writer didn't go to that interview.

C．The writer had been searching for the man.

D．They kept in touch with each other since then.

4. What is their attitude towards each other?

A．Cod.

B．Worried.

C．Grateful.

D．Trusty.
