For decades, doctors have warned patients that too much salt can be bad for the heart. Heat attack has long been considered a grown-up problem, but a new research suggests that salt is starting to affect children. Eating too much salty food when you're young can lead to health problems later.
Salt is made up of two elements: sodium and chlorine. Dietary guidelines recommend that adults and kids aged 9 — 13 shouldn't consume more than about a teaspoon of salt daily. The average American eats twice this amount. This worries doctors because too much sodium results in the body producing more blood. To pump the extra blood, the heart has to work harder. This causes a rise in blood pressure a measurement of how stressed the heart is. High blood pressure often leads to heart disease.
A kid with high blood pressure is more likely to become a grown-up with high blood pressure. Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. Drinking fewer fizzy drinks makes kids less likely to gain weight, become obese and develop high blood pressure.
Salt can affect more than just your heart and weight. A recent study found that a growing number of kids in the US are suffering from kidney stones. This painful condition usually affects people aged over 40. Now, kids as young as five are getting it.
Cutting down on salt can be hard, but you can retrain yourself to prefer less salty food. The best way to reduce the amount of sodium you eat is to make changes gradually. Start by adding half as much salt to your dinner as you normally do. Switch to fresh foods instead of canned and bottled versions. And go easy on the condiments (调味品). You might also want to start reading nutrition labels. You may be surprised to learn that there are 1,150 mg of sodium in a double cheeseburger, and over 2 ,000 mg in many frozen meals.

I like watching TV very much for I think it has many advantages（长处）. First of all, watching TV is a good rest. After a day of hard work, we need a good rest. Watching TV can make our mind and body not tired any more because of the pleasant music and TV plays.
Besides, watching TV is entertaining（娱乐消遣）. There are many kinds of entertainment, such as sports activities（活动）, singing and dancing concerts, plays and films all over the world at every time. It's not possible for us to go to every place to enjoy all the activities within a short time. We need at least over ten hours to fly from New York to Paris, a week by train from Beijing to Moscow and an hour to drive from Queens District to Manhattan District. But within just one second, TV can bring us from an NBA game in New York to a fashion show in Paris by changing the channels.
Most important, watching TV is educational（教育）. Our children can learn every kinds of subjects through the educational programs and the special reports on TV, and it's easy for them to learn Chinese from a Chinese teacher in Beijing and to learn Russian lessons from a Russian teacher in Moscow. Even we can learn how to behave well from the TV plays. Meanwhile, a teacher can teach millions of students without a huge classroom.

【推荐2】If you overheard a conversation on a bus, do you think you could tell the personality of the people who were chatting, from the words used and the topics discussed?
Introverts (内向的人) and extroverts use language very differently. Researchers led by Camiel Beukeboom at VU University, Amsterdam, asked a group of volunteers to look at photos of different social situations and describe what was going on. They found that extroverts’ language tended to be more abstract and “loose”, while introverts spoke in more concrete terms.
But it's not just about extroversion vs. introversion. Language also reveals other aspects of our personalities, including how conscientious (一丝不苟的), open-minded, and neurotic (神经质的) we are.
The open-minded say: “You just need to be heard.”
The neurotic say: “I carry around a monstrous sadness.”
The idea that we reveal something fundamental about ourselves every time we speak and write is a little disturbing.
I think I’d better stop writing now before you discover what mine is.
| A．This makes psychological sense. |
| B．Not all findings are particularly surprising. |
| C．The conscientious say: “We can work on it.” |
| D．We are often reminded to “choose our words carefully”. |
| E．Personality also shines through in creative writing. |
| F．Most of these studies have looked at the language we use in separate ways. |
| G．But it also offers an opportunity to change the way you are seen by others. |
【推荐3】If you're like most pet owners, you probably talk to your pet all the time, even if you feel a little silly about it. But experts say your pet is actually “talking” back to you, even if you don't totally understand what they're' trying to say. Cats and dogs are extremely cognitive(认知的)beings and communicate with us all the time. A pet's cognition starts developing as soon as they're born and changes with age just like humans.
What is cognition?
How do you notice cognitive changes?
●They appear confused or cannot remember their training. Forgetting tricks or house training can be clues.
●
●Aggression. Sudden aggression toward strangers and even family members can be a sign that they've lost the ability to recognize people.
● Lack of appetite.
●Change in sleep-wake cycle. Sleeping all day and staying up all night is not normal behavior and may be a sign of something more.
Giving your pet good nutrition is extremely important.
| A．Lack of interaction or affection. |
| B．They aren't interested in anything. |
| C．It's not always easy to notice these. |
| D．Pets have cognition the same as human. |
| E．Nutrition helps bridge the gap for cognition as your pet ages. |
| F．Your pet may forget where their bowl is or when to expect food. |
| G．Cognition is the ability to learn something and do complex tasks. |
【推荐1】Life has gone mostly online for many people around the world. With more people going online during the COVID-19 pandemic, global Internet traffic has become a big problem. Between January and late March, an increase in Internet traffic made many major. cities experience Internet traffic jams.
Video meetings, online classrooms and stay-at-home entertainment have become a daily routine. This increase in traffic is testing the Internet's strength. In March, major phone networks in the UK experienced mass outages（断供）. People were not able to take calls, receive messages or use mobile data.
In the US, major telecommunications companies like AT&T said traffic was up 21 percent month over month. Video streaming services like You Tube, Netflix and Facebook have cut their picture qualities and download speeds. This is being done to reduce network traffic jams.
China has seen an Internet traffic increase of around 50 percent compared to the end of 2019. The country's network speeds went down sharply in early February. However, they returned to normal soon afterwards and have been working well. This is due to China's work in building network infrastructure（基础设施）, especially 5G technology. By the end of February, 164, 000 5G base stations had been built nationwide. This has given Chinese networks the power to handle increased traffic.
“If there were no such development in the Internet network field, people could hardly enjoy such a colorful life at home. Online working and teaching could never be realized so smoothly,” said Wen Kun, an official with the Ministry of Industry and Information Technology.

【推荐2】Do you want to be a successful person? Would you like to know how successful people usually think and what drives them? Here I am going to tell you the key to success that successful people share.
First of all, successful people never blame someone or something outside of themselves for their failure to move ahead. They realize that their future lies in their own hands. They understand that they can’t control things in life, such as nature, the past and other people. At the same time, they are well aware that they can control their own thoughts and actions. They take responsibility for their life.
Perhaps what most separates successful people from others is that they live life “on purpose” — they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to deal with things around them. They hold the view that when they live their life “on purpose”, their main concern is to do the job right. They love what they do. People want to do business with them because of their commitment. To live their life “on purpose”, successful people find a cause they believe in and create a business around it.
Besides, they never give up easily. Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals. Top achievers always bear in mind what they don’t have forever. Rather than see this as negative or depressing, they would use the knowledge to spur themselves on and go after what they want energetically and passionately.
So keep in mind what successful people always hold to be true so that you will have a clear idea of what you should do to be successful in life.
1. The underlined word “spur” in Paragraph 4 probably means “_____”.| A．interest | B．equip | C．depend | D．inspire |

| B．you should know your strengths and weaknesses |
| C．you shouldn’t blame others for your failure |
| D．you shouldn’t waste time |
| A．explain the exact meaning of success | B．share with readers the key to success |

【推荐3】How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of stars.
But scientists believe there are some things in the sky that we will never see. We won’t see them with the biggest telescope (望远镜) in the world, on the clearest night of the year. That’s because they are invisible (看不见的). They’re the mysterious dead stars called black holes.
You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn’t seem to be getting old or weak. But stars do burn out and die after billions of years.
As a star’s gases burn, they give off light and heat. But when the gases run out, the star stops burning and begins to die.
As the star cools, the outer parts of the star pull in toward the center. The star is squashed (挤压) into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball. If the star was very big, it keeps being squashed inward until it’s packed together tighter (紧的) than anything in the universe.
Imagine if the Earth collapsed until it was the size of a tiny marble (玻璃球). That’s how tightly this dead star, a black hole, is packed. What pulls the star in toward its center with such power? It is the same force that pulls you down when you jump – the force call gravity. A black hole is so tightly packed that its gravity absorbs everything – even light. The light from a black hole can never come back to your eyes. That’s why you see nothing but blackness.
So the next time you look up at the night sky, remember: there’s more in the sky than meets the eye! Scattered (散落) in the silent darkness are black holes – the great mystery of space.
1. What might happen after a star dies?| A．The star might become a black hole. | B．The Earth might be hit by the star. |
| C．The sky might become much darker. | D．The gravity might totally disappear. |
| A．Its gases run out. | B．It hits other stars. |
| C．It gets too hot. | D．Its light fades away. |
| A．Rolled. | B．Ran. | C．Fell inward. | D．Spread out. |
| A．Most black holes are too far away. | B．We don’t have a powerful enough telescope. |

【推荐1】It was my first year of teaching. I was young and inexperienced, and had class after class of twenty kids just waiting for me to make a mistake.
After a particularly long night of grading papers and thinking about how many weeks I'd left until I could breathe, I had one of those mornings when I began to question my job choice. I'd become a teacher to help kids. Instead, I felt like I couldn't even help myself anymore. It was just Mother's Day, and as I sat at my desk surrounded by lesson plans, I wondered how I'd ever have enough energy to have children of my own.
That was when I heard a knock at my door. One of my students came in — the cool basketball-playing country boy who had accidentally broken my favorite snow globe so that I couldn't display nice things in my classroom. He handed me a large flower that probably came from his family's farm. He'd stuck a bird feather in it.
''I got you a Mother's Day gift,'' he said in a low voice. Most middle school and high school teachers don't receive presents. Christmas and Teacher Appreciation Day had already come and gone without any gifts. I was so shocked that I just stared.
Made nervous by my silence, he said, ''You know…since you're like a mother to us, I thought you should get a present, too.''
I smiled and told him he was the sweetest person in the entire world, and that I just loved it. Based on his smile, I knew I'd done enough work of making him feel quite proud of himself. What made that twelve-year-old bring me a homemade present? I'll never know. Once he left the room, I locked the door. And I cried. That moment helped me get through the rest of the school years.

【推荐2】If you want to learn a language and become fluent in it, you really need to start as early in life as possible, because the older you get, the harder it can be to get your tongue round new words and sounds. However, that is not a reason to put off learning a language later in life, because there are still many advantages to it.
As you get older, it can become more and more tempting to stick to things you are most familiar with. However, giving yourself something new to do can help to keep your brain active, and the more active your brain is, the younger you will feel.
We all need new challenges every now and again. It makes life interesting. Don’t set your expectations too high-you aren’t going to become fluent in a couple of months, for example. Instead, set yourself short-term goals-to finish a text-book or to practice your skills on a language speaker. The challenge will provide you with a renewed energy for life.
Many people, especially when they are older, put off going overseas because they are worried about communicating with the local people. However, once you start to learn a language, you will have much more confidence to travel in countries where the language is spoken. Once you are able to buy things, ask directions and have free conversations, you will find traveling much more enjoyable.
One of the best reasons for learning a language later in life is simply because you can. When younger, you probably had little spare time. Now, you probably have more time in hand because your family has grown up and you may even have retired. There are so many tools you can use to learn languages these days (the television and Internet are two obvious ones), so you may not even have to pay.

【推荐3】One of the most famous archaeological discoveries in all of history is The Terracotta Army. It's also called the Terracotta Warriors and Horses and they were found by farmers digging for a well in Xi'an in 1974. Becoming a UNESCO World Heritage site in 1987, the spectacular figures continue to attract millions of visitors from all over the world. Yet the excavations (发掘) are unfinished. Famously, archaeological work at the site and the accompanying Tomb of the First Qin Emperor has been allowed to slow down until technology advances enough to preserve the art works currently buried underground. In addition to this, safety concerns have been raised regarding the unusually high levels of mercury (水银) found on the soil. It's said that this is from the mercury streams which were in the floor of the burial chamber, but only time will tell if this ancient tale is true.
Currently 8000 soldiers have been found, each one with a distinctively different look. This was achieved through an early use of assembly-line (流水线). The warriors were assembled using moulds（模具), with 8 different heads to choose from, and features being added by skilled craftsmen. Studying the warriors and their horses offers historians an important insight into this period in Chinese history. The technology used to assemble the underground army was truly remarkable. Over 40,000 bronze weapons were found, and after more than 2000 years they still appear sharp. How is this possible? The ancient Chinese managed to use protective chrome plating (镀铬), something which was thought to have been invented in Germany in 1937! Chinese metallurgy（冶金） was thousands of years ahead of its time.
When it is finally uncovered, the sight will truly be spectacular and much more will be understood about China's first Emperor and the level of technology the ancient Chinese possessed.

【推荐1】When I was a child growing up in Ohio, the butterflies would sometimes pass through on their way to Mexico. And it was awesome to see football fields full of them — and I wanted to revisit that on a larger scale. I knew I had to go to see the migration in Mexico.
But I was on a budget. I didn’t want to rent a car in Mexico or take a bus to Valle de Bravo, the starting point for most butterfly adventures, so I called the guys at the Muddy Boot, travel experts in Mexico who can make almost anything happen at a reasonable rate.
And so, on January 2, I found myself in the Muddy Boot van (货车), being driven two hours from Mexico City to Valle de Bravo, a lovely town on a volcanic lake which is a central point for the butterfly journeys. I booked a two-night stay at the Hotel Rodavento, an all eco-friendly hotel with individual wooden houses spread throughout the forest and around a lake.
The first sanctuary (保护区) I visited was Piedra Herrada, a popular destination, as it is only 40 minutes away from Valle de Bravo. The climb up is tiring. It is advisable to hire a horse. But the horse cannot take you all the way, and there is some hiking in thin air, so you must be patient, drink a lot of water, and be in reasonably good shape.
The walk is more than worth it, though. As I struggled to catch my breath, I looked up and lost my breath again. At first glance, the trees had turned into different shapes, but on closer inspection, every inch of them was covered with butterflies.
A few flew through the air (Most of them were not warm enough). As the sun rose, they began to come alive. Soon the air was filled with flying butterflies, transforming the forest into something magical and straight out of a fairy tale.

【推荐2】I work as the reception manager at my hotel.
A booking came in a few weeks ago with a note attached that a guest would be travelling with her deaf father. This note helped us in preparing for their arrival. As they would be here for a number of days, his daughter wanted to make his trip to Ireland as smooth as possible.
Upon seeing this note and knowing I would be the one to check them in, I decided to learn some very basic sign language. I greeted the guest in my usual fashion, asking for the surname on the booking. Once I heard the name，I immediately realized who was standing in front of me.
I had been learning for two weeks how to say: “Welcome to Ireland. My sign language is terrible, but please, if you need anything during your stay, just let me know and we will help you.”
I smiled at the father and daughter in front of me. Turning to the father, I greeted him in ASL (American Sign Language) and began the bit I had learned for him. His daughter broke down crying and told me I was sweet. But the father just smiled and was so happy. Honestly, seeing his reaction was enough for me. It was absolutely worth the last few weeks of learning basic ASL.
Sadly, I wasn’t working the day they checked out, but they left a gift for me, a small box with some chocolates and a book on ASL. Inside was a note saying: “Thank you very much for what you did. My father has been in amazing spirits from the time you checked us in and insisted we get you a gift before we left. You have no idea how much this meant to my father and me, and we can’t thank you enough. You've made his trip very special with one simple gesture.”
I cried for a solid five minutes when I came into work the next day and found this gift in my locker.

【推荐3】When I was at school, read Gavin Maxwell’s book Ring of Bright Water. Affected by the story, I travelled to Sandaig and saw the house and one of the otters (水獭) with Andrew Scot (Gavin’s otter keeper). Later, I wrote to Gavin about my visit to his home and surroundings, and after the fire that destroyed Sandaig house he invited me to his new home in the remote countryside on Eilean Ban.
Gavin expressed the hope that I would take advantage of my interest in keeping a diary and write. On his death, I entered a competition for young writers about my experience of meeting Gavin, with story titled Bach to Paradise. Melvyn Bragg, the competition’s judge, spoke highly of my story, which he found to be “very moving” and added that he had enjoyed it “very much”.
Encouraged by Melvyn’s comments, I became a regular contributor to The Northumbrian Magazine, until I left the north-east of England in 1992 to live on the Lancashire-Yorkshire border. To emulate Gavin’s lifestyle, I chose to live in a remote farmhouse as what he did on the edge of the Bronte moors for over 20 years, with only wildlife for neighbors. During this time, I earned my living as countryside ranger (护林人) and helped the public to learn about the countryside through guided walks and events and by giving lectures.
Then I became a teacher, photographer and writer. Without Gavin, it is unlikely that I would have achieved the same success.
Thanks to the way of life I chose, my daughter, Mary, has recently gained her honorary degree in zoo management. She told me she had been inspired by my sparking (激发) her curiosity in the wildlife around our home.
