Music helps us exercise—but why does it have this effect (影响)? Experts say there are two main reasons. The first is simple: Music distracts us. When we listen to a song we like, our brain pays attention to the music. For example, after we exercise for 20 minutes, our body might be tired. But we may not feel this immediately because we are listening to music. So we exercise a little longer.

        . When we hear dance music, for example, we naturally start to move to the beat. An upbeat song also puts us in a good mood, so we feel happier. This gives us energy and helps us exercise longer. Music with a quick and steady beat is good for exercising. But the music shouldn’t be too fast, says sports psychologist Dr. Costa Karageorghis. Generally, songs in the range (范围) of 120-140 beats per minute (BPM) are the best.

A new study by cognitive scientist Tom Fritz suggests this is only part of the explanation, however. In an experiment, Fritz put 61 people in small groups. They all then exercised twice. One time, each group worked out while listening to music for six minutes. Another time, they exercised for six minutes on special Jymmin machines. The name Jymmin is a combination of “jammin” and “gym”. Using these machines, each group made music as they moved. At the end, 53 of the 61 people said the same thing: They felt less tired when they exercised on the Jymmin machines. When we exercise and make music-especially with other people working out seems to be easier.

How does Fritz explain this? Maybe people did better on the Jymmin machines because they had more control, he says. People created the beat. They could make it go faster or slower. Also, the activity was social. Each group was making music together and having fun. Fritz believes that Jymmin exercise may have other advantages (优势), too. He wants to find out if it can help with more serious conditions. For example, it may even be a good way to treat depression (抑郁).

But ugly fruits should be loved, too. In recent years, a new crop of “ugly produce” companies have been around the U.S. These start-ups sell those ugly fruits that supermarkets refuse. And they send them right to your door.

The companies say they’re on a mission(使命). They want to stop billions of pounds of imperfect produce(农产品)from going to waste. Think of it this way: Is a banged-up (be knocked and some places broken) banana any less tasty in a peanut butter sandwich? Why should it be thrown away?

Sounds like these companies have the right idea. They even offer deep low prices. That’s great news for customers. But not everyone is happy. Some people say these companies may be thinking only about themselves.

Imperfect produce isn’t always wasted.

Many small farmers had already been selling imperfect produce to customers and farmers markets. Then the ugly produce companies started growing up. These companies, such as Imperfect Produce, can offer more fruits and veggies from large farms around the country. They make it harder for smaller farms to compete. So the farmers are losing money.

Also, ugly fruits and veggies already have uses. Take the food service industry for example. There, produce is sliced, diced, blended, and more. No one cares if the fruit is pretty or ugly. On farms, fruits can be fed to animals. Rotted(腐烂的)fruit is added back into soil for nutrients. And, what’s more, ugly produce companies have been charged with taking food away from the needy.

Are these start-ups causing more bad than good?

Not So Bad, After All?

What do ugly produce companies say? They are guarding themselves.

In March 2019, Imperfect Produce told people that the company doesn’t take away from the needy. It gets resources from farms only after food banks take what they want, it said. Also, the company often gives food to food banks. Put that in your food basket!

It is true that produce goes to waste in America. The Department of Agriculture has said that food waste is a big problem. In fact, about 30 to 40 percent of the country’s food is wasted.

But Imperfect Produce says both farmers and ugly produce companies can help reduce food waste. It doesn’t have to be either-or.

No matter whose side you’re on, remember this: It’s what’s on the inside that counts.

【小题1】What does Paragraph 3 mainly talk about?
A.Ugly produce companies are doing more good than bad.
B.Not everyone supports ugly produce companies’ missions.
C.Ugly produce companies are loved because of lower prices.
D.Ugly produce companies make the most use of imperfect produce.
【小题2】What is the most suitable for the ?
A.The Ugly Truth?B.Not So Good, Above All.

A.It’s important for smaller farms to get more customers to make money.
B.Food waste is caused because supermarkets refuse ugly produce.
C.Ugly produce companies sell imperfect produce to prevent waste.
D.Customers are interested in stopping food waste and saving money.

The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it’s true. 【小题1】

Wrong idea number 1: 【小题2】

Well, inventing means creating something “new”, but the idea could come from something that already exists (存在). The Wright brothers, for example, got the idea for building a “flying machine” from watching birds.

Wrong idea number 2: Inventors are born, not made.

There are a lot of factors (因素) that make innovation (创新) possible. 【小题3】 He was born with a special talent for music. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was in kindergarten. Thomas Edison said that being an inventor was “99% hard work and 1% inspiration”! 【小题4】 As one inventor said, “A failure is the right answer to the wrong question!”

Wrong idea number 3:Inventors are always old people.

【小题5】 Here are two examples of young inventors: Louis Braille went blind when he was a child. When he was 15, he invented a system of reading and writing for blind people that is still used in most countries today. As ạ young man, George Nissen was watching trapeze artists (空中飞人) in a show. He watched how they fell into the net and then bounced (弹起) back up again. This gave him an idea and he invented the trampoline (蹦床).


阅读短文,把A~E五个句子填入文中空缺处,使短文内容完整。
A.Take Mozart, for example.
B.An invention has to be something completely new.
C.Don’t believe that you can’t invent something when you are young.
D.Very successful creators don’t give up when they get something wrong.
E.Maybe you have the wrong idea about inventing, so read on to discover the truth.
