When it comes to exercise, do you swear by working up a sweat with a good run, or do you prefer to take a walk? It turns out both runners and walkers get health benefits compared with couch potatoes. But is one really better than the other for fitness?1.
It’s always good to get any kind of exercise and it’s important that you choose exercise that you can do regularly.2.For instance, running for half an hour burns about twice the calories as a half-hour of walking. But if the walker covers the same distance, just over a longer period of time, he/she will burn the same calories.
What about other health benefits? Running and walking are both excellent for heart health. When you run, your heart works harder than when you walk.3.If runners and walkers burn the same number of calories every day, both groups have a lower risk of heart disease than inactive people.
4. For instance, running or walking at least 30 minutes a day may help lessen mild bone loss. And contrary to what you may think, runners don’t suffer from arthritis (关节炎) more than non-runners. In fact, their risk for arthritis is about 15% lower than for those who don’t exercise at all.
You don’t have to feel torn between running and walking.5.
A.Most people will say “yes” to this question.
B.Both types of exercise are also good for bone health.
C.It doesn’t matter if you run or walk as long as you keep moving.
D.Let’s first take a look at the health benefits of running and walking.
E.But that doesn’t actually mean that runners have better heart health than walkers.
F.One large study found runners might have a lower chance of getting heart disease.
G.The main difference between walking and running is that running burns calories faster.
Algorithms (算法) affect nearly every part of a person's experience on the Internet. Search engines are most people' s entry to the Internet.If a person wants to find information about something, they usually start with a search bar.As soon as they start typing or choosing links,the algorithm starts gathering data about every choice users make and uses that data to try to find the websites or information that most directly relate to what the user is looking for.
The problem with algorithm is that they can limit the kinds of information people see,says MacMillan,a reading researcher with Project Information Literacy (能力). He argues this can be harmful to people's critical thinking and lead them to believe that only one point of view is correct.
Companies also pay to post advertisements for products that could relate to users' search data. For example,if you search for places to take a vacation,you will likely start to see ads for travel companies, flights or hotels.
Renee Hobbs, director of the Media Education Lab at the University of Rhode Island, however, argues that algorithms are not all bad. She says search engine algorithms can help you find what might be the most useful information faster. But she says it is in the interests of Internet companies to keep users on the Internet for as long as possible so they see more ads.
The current generation of young people grow up using the Internet and they are prone(易于遭受) to distrustful information.That is why schools must train students how to use the Internet more wisely in their Studies.It is the duty of education to keep students informed about the world around them. Yet it is not the duty of education alone. And lawmakers should consider increasing data protection rules. Individuals can also use a wide variety of websites to avoid algorithmic controls.
1.How do algorithms affect users' Internet experience?
A.They lead to slower Internet connection.
B.They block ads for users automatically.
C.They always help users get reliable links.
D.They determine the content users receive.
2.What is Hobbs' attitude to algorithms?
A.Doubtful. B.Supportive.
C.Objective. D.Indifferent.
3.What can be concluded from the last paragraph?
A.Young people fall victim to the Internet.
B.Data protection rules are already enough.
C.Education is fully responsible for algorithmic controls.
D.Joint efforts are needed to handle algorithmic controls.
4.Which column of a magazine is the text most likely from?
A.Science. B.Entertainment.
C.Advertisement. D.Fashion.
The low percentage of women in science ，technology，engineering，and mathematics(STEM) careers is often attributed (归因于) to men being believed to be better at the sort of thinking those fields require. Though studies have debunked the view,they have largely been based on results acquired from various several standardized tests. Now, researchers from Pennsylvania' S Carnegie Mellon University have found evidence that is hard to overlook; MRI (磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems.
The groundbreaking study to evaluate the biological gender differences in the math talent of young children was led by the university' s professor of neuroscience, Jessica Cantlon. For their study ,the team selected 104 young children, between 3 and 10 years old, divided almost equally by gender. The scientists used a functional MRI to observe their brain activity as they engaged in math tasks. These included watching age appropriate educational videos and doing math exercises such as counting and addition,as well as reading for comparison.
“We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non math content like reading or the alphabet, Cantlon said.“When we do that in lite girls, we see a particular network of the brain respond,and when we do that same analysis in boys, we see the exact same regions.”
So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions. Previous studies have indicated that parents tend to spend more time with young boys in play that inspire spatial cognition (空间认知)-such as toys that involve learning number skills and shapes and solving puzzles. Educators were also observed to spend more time with boys during math class.

Rioghna and Hannah Pittock spent the first few minutes feeling sorry for themselves. Rioghna,a junior at Rochester Mayo High School, had spring sports to play. Hannah,a senior at University of Chicago , was going to have a spring break in Aruba. However , both were canceled because of COVID-19. But they soon recovered and now they are sitting at home , solving Rochester's problems in their way. Pointing to the computer screen, Hannah tells her sister,“She is a nurse and her child needs to be matched.”

With more and more teens joining in, the two sisters decide to launch Step Up To Shop,a platform for teens to deliver groceries to seniors.
Rioghna acknowledges people of her age get a bad reputation as smartphone-addicted and selfish. The Pittock sisters are proving otherwise,“Amid the pandemic，people should be allowed to be upset and allowed to be a little bit down about the upset in their lives, but it's about something bigger and recognizing we all have our part to play here,”Rioghna says.

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。
Once, when I was a teenager my father and I were standing in line to buy tickets for the circus. Finally there was only one family between us and the ticket counter.
This family made a big impression on me. There were eight children, all probably under the age of twelve. You could tell they didn’t have a lot of money. Their clothes were not expensive, but they were clean, the children were well-behaved, all of them standing in line, two-by-two behind their parents, holding hands. They were excitedly talking about the clowns, elephants and other acts they would see that night with their brothers or sisters in a low voice. One could sense they had never been to the circus before. It promised to be a highlight of their young lives.
The father and mother were at the head of the pack, standing proud as they could be. The mother was holding her husband s hand, looking up at him as if to say, “You are my knight in shining armor.” He was smiling and responding in pride, looking back at her as if to say “You got that right”. The ticket lady asked the father how many tickets he wanted. He proudly responded "please let me buy eight children’s tickets and two adult tickets so I can take my family to the circus.
The ticket lady gave the price. The man’s wife let go of his hand, lowered her head and her lips began to shake. The father leaned a little closer and asked, “How much did you say?” The ticket lady again told him the price. The man obviously didn’t have enough money.
How was he supposed to turn and tell his eight children that he didn’t have enough money to take them to the circus? Actually we were not wealthy in any sense, so I understand how the kids would feel. I felt sorry for them.
