How Many Cups of Coffee per Day Are Too Many?

From cappuccinos to cold brew, coffee is a must-have to start the day for many people. 1. However, a new study suggests too much coffee can be harmful.

This is what a recent study shows. 2. A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won’t hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee.

Knowing the limits of what's good for us and what's not is necessary. 3. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure. 4.

Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful.

5. Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day.

A. Drink no more than six cups per day.

B. Over the limits and our health will pay for it.

C. Coffee is the most popular drink in the world.

D. But of course, don't forget to listen to our body.

E. The relation between them is quite complicated.

F. As we know, it is a key heart disease risk factor.

G. It sets you off on an energetic morning and prepares you for a busy day.

    Maybe it's because it was our first purchase as homeowners. The salesman must have spotted just how green we were, so he began persuading. And soon he led us to a classic leather chair. All these years later, I remember he used words like rich and handsome, the thing every living room needed.

We believed him. So we bought that chair — just less than $100, a great deal in the 1970s for a young couple!

How we loved that chair! It always occupied a place of honor in our various living rooms, moving with us from our first tiny house to our beloved new house.

Somehow, conversations were better on that chair, and life was more fun around it. Three daughters spilled their secrets on it. Old friends seemed to be attracted by it on those wonderful occasions. Crazy as it sounds, that leather chair seemed to have — well, powers. All for good.

At first, we didn't really care that the leather was showing signs of wear or that it had lost its sheen (光泽). But in our most recent move, when the chair was moved in our new living room, it suddenly looked terribly lonely sitting close to newly painted walls and a couple of shiny new tables.

My husband and I tried but still we couldn't ignore the rough spots. Our chair had a skin disease. Even our adult kids raised eyebrows, urging us to at least remove the chair to some dark comer of the room. Neither of us could imagine such a retirement for it.

So we had an inspired idea. We'd call in an upholsterer (修理工) to give our old chair a whole new life. Our friend Joe studied the chair and then took out a simple leather conditioner. He explained that although it wouldn't work miracles, it would definitely get our weary chair looking younger again. It certainly doesn't look new, but its seat and back are shining, and some of its deeper wrinkles have lightened.

Best of all, it's back in the living room, looking like a wise old friend to the furniture around it. And, yes, there it will stay.

Because some things, like some people, just deserve a happy old age.

1.How did the salesman persuade the author into buying the chair?

A.By thinking highly of the author.

B.By saying that the author was green.

C.By describing how great the chair was.

D.By comparing the chair with others.

2.What is the fourth paragraph mainly about?

A.Sweet memories with the chair.

B.Various functions of the chair.

C.People's comments on the chair.

D.Family activities and parties of friends.

3.Why did the author finally decide to repair the chair?

A.Because he was persuaded by Joe.

B.Because he didn't have enough money.

C.Because it showed signs of hardness.

D.Because it couldn't match his new house.

4.What can we learn from the text?

A.East or west, home is best. B.From saving comes having.

C.It is never too late to mend. D.Old friends and wine are best.

    A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.

1.What does the underlined word "unaltered" in paragraph 3 refer to?

A.Unchanged. B.Undivided.

C.Unadopted. D.Unfinished.

2.Why do mosquito populations have to be controlled?

A.Mosquitoes cause genetic changes in humans.

B.Mosquitoes spread some deadliest diseases.

C.Mosquitoes limit people's ability to reproduce.

D.Mosquitoes make traditional vaccines ineffective.

3.What has been the most successful way of reducing mosquito numbers?

A.Editing genes in female mosquitoes.

B.Sterilizing male mosquitoes before mating.

C.Limiting both genders' reproduction ability.

D.Using pesticides and removing stagnant water.

4.What can we learn from Stephen Dobson's words?

A.The things described in this paper are not practical.

B.A better way of mosquito control is yet to be found.

C.Xi Zhiyong' s method has proven to be very effective.

D.A new tool is needed in order to improve Xi's research.

    Runners never forget crossing the finishing line at their first marathon, and that will be especially true for Mike Kohler. When Kohler crossed the starting line in Fargo last Saturday, he thought he was going to run 13.1 miles, his first half marathon. Six hours later, he had "mistakenly” completed his first full marathon, 26.2 miles.

Kohler, a 26-year-old plumber (水管工) who now lives in West Fargo, had lined up for the half marathon that he hoped to complete in 150 minutes. He didn't realize he was in a starting fence with the full marathoners. Several miles later, Kohler began to realize he was on the course for the full marathon. "The 8-mile mark was when I figured out that I had made a mistake," he said. "Between then and 13.1, I debated with myself about what I should do.”

At some point — he doesn't remember when — he doubled down on the distance. "After I decided I was going to keep going, the thought of quitting didn't come back. Run, walk, or crawl, I wanted to finish," he said.

Until Saturday, Kohler's longest race was a 10-kilometer run, just over 6 miles. Even the most casual marathoners do a training run of 18 miles before the race. From his experience, he said he learned one thing: sometimes people can do more than they think they can.

After his long race, he went right back to work, put in a 10-hour day and then boarded a flight to Scotland for a vacation. "I was pretty sore, but I found the more I kept moving, the less sore I was, so I tried my best to go about life normally — minus running,” Kohler said from Glasgow. "I needed a break from that for a bit."

Not for too long, though. He's already considering the Bemidji Blue Ox Marathon in October.

1.When did Kohler realize that he made a mistake?

A.Before starting the race.

B.After running 8 miles.

C.When being with the full marathoners.

D.While lining up for the half marathon.

2.Which of the following best describes Kohler?

A.Determined. B.Cooperative.

C.Open-minded. D.Well-prepared.

3.What can we infer from the text?

A.He went to Scotland to get a break from work.

B.He had never trained for the full marathon before.

C.He decided to complete the race at the 8-mile mark.

D.He was debating with himself when he finished the race.

4.What might be the best title for the text?

A.Life Lies in Movement

B.Life Means Never Quitting

C.One Can Always Do More Than He Can

D.One Mistakenly Runs Full Marathon Not a Half
