When it comes to exercise, do you swear ...

    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.

 

1.D 2.G 3.E 4.B 5.C 【解析】 本文是一篇议论文。事实证明,跑步者和步行者都比电视迷更健康。文章论述了锻炼的好处。 1. 根据上文But is one really better than the other for fitness? (但在健身方面,其中一种真的比另一种更好吗?)可知,接下来要讲述跑步和步行在健身方面各自的好处。故D. Let’s first take a look at the health benefits of running and walking.(让我们先来看看跑步和步行对健康的好处)符合语境。故选D。 2. 根据下文For instance, running for half an hour burns about twice the calories as a half-hour of walking. (例如,跑步半小时消耗的热量是步行半小时的两倍)可知,跑步比步行消耗的热量快。故G. The main difference between walking and running is that running burns calories faster. (步行和跑步的主要区别是跑步燃烧卡路里更快)符合语境。故选G。 3. 根据上文When you run, your heart works harder than when you walk.(当你跑步时,你的心脏比你走路时更卖力)及下文If runners and walkers burn the same number of calories every day, both groups have a lower risk of heart disease than inactive people.(如果跑步者和步行者每天消耗相同数量的卡路里,两组人患心脏病的风险都比不运动的人低)可知, E. But that doesn’t actually mean that runners have better heart health than walkers. (但这并不意味着跑步者比步行者有更好的心脏健康)能够承接上下文。故选E。 4. 根据下文For instance, running or walking at least 30 minutes a day may help lessen mild bone loss.(例如,每天至少30分钟的跑步或步行可能有助于减轻轻度骨质流失)可知,B. Both types of exercise are also good for bone health. (这两种运动对骨骼健康都有好处)能够承接下文。关键词是bone。故选B。 5. 根据上文You don’t have to feel torn between running and walking. (你不必在跑步和步行之间左右为难)及上文内容可知,跑步和步行都对健康有好处。故C. It doesn’t matter if you run or walk as long as you keep moving. (不管你跑还是走,只要你一直走就好)符合语境。故选C。

    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 technologyengineeringand 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.

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.
