    For some people, walking or running outdoors is a great way to exercise. What may not be so great is seeing rubbish all over the ground. Well, some people are doing something about it. 1. “Plogging” began in Sweden. The name connects the Swedish word “plocka,” which means to pick up, and the word “jogging,” which means to run slowly.

A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community (社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish. 2.

Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community. 3. It can also build closer social connections in a community. When the street looks bad and it’s dirty, you're going to feel bad about the community. You may even feel less safe because of that. So if we’re all doing our part and picking it up, it’s very easy to help beautify it, and help build those social connection. 4. You get to feel some social duty when you do this.

Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories. 5.

As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.

A. Plogging is equal parts of exercise and community service.

B. And that is how plogging was born!

C. And plogging does good to your health.

D. Usual jogging burns about 235 calories.

E. They are plogging!

F. There are people all around the world doing this.

G. You get to know your neighbors.

Me : Hello Dad! I’ve an exam today.

He : All the best son! I’m getting a strong feeling. You’ll rock it today. May god bless you!

Me : Thank you dad. Bye! And I hang up the call.

My friend standing beside me chuckles, “Do you do this before every exam?” I answer, “Yes, I feel good and encouraged, and so do they.” It hardly takes a minute to call up your parents, but it gives a lot of confidence and makes their day too.

Not calling up parents is indeed a common mistake college students make. For me the most common mistake is treating it like school. When I went to university, most of the people around me came straight from school. They had the thought like children who were being forced to do something. They skipped classes, sat at the back talking during lectures and even didn’t do the reading! They were still in “school” mode, thinking that the point was to get through it with the least effort.

For my part, I was there after working in a beer factory for three years. I knew that I had gone to university because I wanted to learn. I wasn’t there because my teachers at school made me go, or my parents made me go, or because my friends were all going. I had chosen to go. I think that this put me in a different mind. I read all the set texts and I went to all the lectures and seminars. Don’t get me wrong. I had fun too, but I was there to learn and I learnt a lot. I enjoyed it and it was rewarding to learn about the authors, their works, the critic's opinions etc.

The kids around me thought that reading six novels for a module and going to a lecture for each novel was too much work. They would read one novel, go to the lecture for that one and write their essay on that one book. They thought that they were really clever to work out an easier way of doing it. But they were tricking themselves out of an education!

There are other mistakes that may cause future regrets for the college students. A large number of them focus too hard on getting good grades, showing no interest in out-of-class side projects.  Some complain that they are too busy because of school. As a matter of fact, they do not seriously treat all the free resources that universities have to offer.

On some Swedish trains, passengers carry their e-tickets in their hands. About 3,000 Swedes have chosen to put microchips (微芯片) beneath the skin between fingers. The chips, which cost around $150, can hold personal facts, credit-card numbers and medical records. They depend on Radio Frequency ID (RFID), a technology already used in payment cards, tickets and passports.

There are 10,000 people with chip implants (植入) around the world. Sweden, home to several microchip companies, has the largest share. People can order do-it-yourself kits. And sometimes they get T-shirts that say “I got chipped”.

Jowan Österlund, the founder of BioHax, a Swedish firm, argues that chips are safer than mobile phones because it is harder to steal information from them. But some people still have worries. RFID chips do not have GPS, but they leave a trail when they are used to open doors, operate printers, etc. In 2004 a Mexican government official and his workmates had chips placed in their arms that tracked who had accessed important information.

So why take the risk? Less trouble is one reason. The equipment for microchip implants exists wherever new payments are accepted. Sweden is well suited, as the world’s second most cash-less country (after Canada).

But the chips have little use unless all companies agree to work together. Few shops recognize this chip implants yet, even those organizations that do have had some troubles in the beginning. When Swedish rail officials began scanning passengers’ microchips, they saw private information rather than evidence of ticket buying. For now the chips are used largely as business cards, keys or to store important information.

So the desire to win notice or admiration is another explanation. Chip enthusiasts want to equip human bodies with technology. Elon Musk, an American businessman has spent money on this technology that connects machines with human brains, which caused fears from some Christians.

1.What is special about the microchips mentioned in the passage?

A. They have already become part of human bodies.

B. They have offered access to personal information.

C. They have become a symbol of modern society.

D. They have used the latest technology in payment.

2.Jowan failed to consider the fact that __________.

A. the information is safer to keep on chips than phones

B. RFID chips can also have GPS as mobiles phones do

C. information on chips is likely to be accessed and let out

D. some microchips have already been equipped with GPS

3.Why are people willing to risk putting chips into their bodies?

A. Because developed countries are well prepared for chip implants.

B. Because they want to save themselves the trouble of cash payment.

C. Because they encourage more companies to recognize chip implants.

D. Because it is an attention-catching technology that makes things easier.

4.We can infer from Paragraph 5 that __________.

A. There is a long way to go before the implanted chips are widely applied.

B. Many companies take a wait-and-see attitude towards this technology.

C. The chip implants have caused difficulty for both users and companies.

D. Microchips always successfully offer information about ticket buying.

I first saw a crayfish (小龙虾) around 2001. A friend brought one into the office and told me it was a female animal that was reproducing (繁殖) on its own. We realized the new type of animal  was reproducing itself by the millions.

We think that in the 1990s, two crayfish got children either in a pet store or in the wild. Something went wrong and one of the daughters laid eggs without any males. It’s not unusual for such a sudden change like this to happen, but normally, the children can’t live on or reproduce, and the new type won’t spread. For some reason, this daughter and her children did.

In some way, many of the new crayfish appeared in German pet stores. They would naturally increase, and their owners would often set the children free, which let the animals reproduce and spread farther. In 2003, scientists officially proved that animals like crayfish were, in fact, reproducing themselves. They’ve gone from that single female 25 years ago to millions, or maybe billions, of the same crayfish found throughout Europe and Madagascar.

In 2018, we published a map of the clones’ genetic code (克隆类遗传密码图). This type is becoming a really useful tool for researchers like me: We can use crayfish-like animals to study everything from cancer development to the effects of drugs on the brain. Now that we know this code, we can start to try it in the lab. For example, we might try to make these animals grow to larger sizes so people can sell them for food. This is already happening in Madagascar. It turns out that crayfish are pretty tasty. It’s easy to get lots of them too because they grow up in about three months and lay hundreds of eggs. Just put one in a pool and wait.

A Chinese boy is reported to have spent about 2 million yuan in studying in New Zealand but failed to get any diploma. He even could not take care of himself and his grandmother had to feed him.

The man in the case is a so-called adult baby, because his deeds make him almost the same as a baby. He cannot take care of himself. He is unable to go to school, let alone finish studies.He even relies on his grandmother to feed him.

However, he burns money faster than any normal student. He spent about 2 million yuan in two years overseas, but could not finish even the preparatory courses. We do not mean to judge his choice，but someone who lacks the basic ability to survive has little chance of success in any modern society.

In a later interview, the mother of the boy was in tears and said she regretted not having taught her son well.She also told the story about how she “educated” her son: meeting all his demands, even the unreasonable ones.When he did not perform well in school, she simply spent money in sending him overseas; she would buy whatever he wanted.That was bad for her and bad for him.

Decoding the young brain

There was a funny experiment to see how a young child would answer a specific question compared to an adult.After the adult had spent some time speaking with the child, he asked the child, “What do you think about me？” The child answered, “You talk too much.” When the adult performed the same experiment with another adult, the reply to the same question was, “I think you're a very interesting person.” Even if the adult felt the same way as the child, his brain allowed him to take a moment，consider the question, and come up with an answer. He could have been annoyed, but his answer didn't reflect it because he was being polite.

The secret lies in the science of the developing brain.The child's honest answer was reflected in the fact that his brain wasn't equipped to filter(过滤) information before answering the question.As a result, he was honest, but he said something that may have been hurtful.However, the child did not intentionally hurt the adult; it's just the way his brain works.As a child grows into adolescence and then into adulthood, that changes.

The human brain is made up of billions of neurons(神经元). In order for our body to execute a command, like getting up from a chair and walking to the other room, the neurons in the brain have to communicate with each other. They also help us employ our senses like taste and touch and help us remember things.

When the neurons send messages, perhaps one sensation(感觉) the person feels is excitement about eating a cookie because it is so delicious. Later, if that person smells a cookie or hears someone talking about a cookie, it can spark the electrical signals that call up the memory of eating the delicious cookie. In an adult, he or she may remember that eating too many cookies can have consequences, like weight gain.But because the younger brain is more impulsive(冲动的), the desire to feel the pleasure of the sweet treat outweighs the consequences.

That is because when a child is young, his brain is “wired” in such a way that he seeks pleasure and is more willing to take risks than an adult.This affects his decision-making process and it is why younger people tend to be more impulsive. Sometimes parents have to tell their children over and over again before the child remembers that something is dangerous or risky. How many times have we heard a parent say, “I tell her this all the time, but she never listens！”

To conclude, what we know about the young brain is that children are more likely than adults to be impulsive.It isn't always necessarily because they are being naughty; it may very well be because of their brains. So the next time you ask a child what he really thinks of you, be prepared for any kind of answer.

No one knew Prince Edward Street as well as Pierre Dupin. He had delivered milk to the families on the street for thirty years. For the past fifteen years a large white horse named Joseph pulled his milk wagon. Joseph was a gentle horse with beautiful spirit shining out of its eyes, so Pierre named him after Saint Joseph.

Every morning at five, Pierre arrived at the milk company's stables to find Joseph waiting for him, Pierre would call, “Good morning, my old friend.”， as he climbed into his seat, while Joseph turned his head toward the driver. And the two would go proudly down the street. Without any order from Pierre, the wagon would roll down three streets. Then it turned right for two streets, before turning left to Saint Catherine Street. The horse finally stopped at the first house on Prince Edward Street. There, Joseph would wait perhaps thirty seconds for Pierre to get down off his seat and put a bottle of milk at the front door.

Pierre knew every one of the forty families that got milk. The cooks knew that Pierre could not read or write; so, instead of leaving orders in an empty milk bottle, they simply sang out if they needed an extra bottle.

Pierre also had a wonderful memory. When he arrived at the stable he always remembered to tell Jacques, the foreman(领班) of the stables, “The Pacquins took an extra bottle this morning; the Lemoines bought a pint of cream ...” Most of the drivers had to make out the weekly bills and collect the money. But Jacques, liking Pierre, never asked him to do this.

One day the president of the milk company came to inspect the early morning milk deliveries.Jacques pointed to Pierre and said:”See how the horse listens and how he turns his head toward Pierre? See the look in that horse's eyes? You know, I think those two share a secret. I have often felt it. He is getting old. Maybe he ought to be given a rest, and a small pension.”

“But of course，” the president laughed. “He has been on this job now for thirty years. All who know him love him. Tell him it is time he rested. He will get his pay every week as before.”

But Pierre refused to leave his job. He said his life would be nothing if he could not drive Joseph every day. “We are two old men，” he said to Jacques. “Let us wear out together. When Joseph is ready to leave, then I too will do so.”

Then one cold morning Jacques had terrible news for Pierre. Jacques said，”Pierre, your horse, Joseph, didn't wake up. He was very old, Pierre.” Jacques said softly. “He is over in his stall, looking very peaceful. Go over and see him.” Pierre took one step forward, then turned. “No ... no ... I cannot see Joseph again. You ...， you don't understand, Jacques.”

For years Pierre had worn a large heavy cap that came down low over his eyes.It kept out the bitter cold wind. Now, Jacques looked into Pierre's eyes and he saw something that shocked him. He saw a dead, lifeless look in them.

“Take the day off, Pierre，” Jacques said. Pierre walked to the corner and stepped into the street.There was a warning shout from the driver of a big truck ... there was the screech(尖锐的刹车声) of rubber tires as the truck tried to stop. But Pierre heard nothing.

Five minutes later a doctor said, “He's dead ...， killed instantly.”

“I couldn't help it，” the truck driver said. “He walked in front of my truck. He never saw it, I guess. Why, he walked as though he were blind.”

The doctor bent down. “Blind？Of course, this man has been blind for five years.”  He turned to Jacques, “Didn't you know he was blind？”

“No ...no ...” Jacques said softly. “None of us knew. Only one ... only one knew－a friend of his, named Joseph ... It was a secret, I think, just between those two.”

The latest IPCC report does not mince words(直言不讳地) about the state of our planet: we must act now to achieve global change at a scale that has “no documented historical precedent(先例)” in order to avoid the climate disaster that would result from a 2 degree C rise in average global temperature. Climate change already affects the world's most helpless people including poor rural communities that depend on the land for their livings and coastal communities. Indeed, we have already seen the clear asymmetry(不对称) of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more.

So far, advocates and politicians have tended to focus on reducing fossil fuel(矿物燃料) consumption through technology and/or policy, such as a sharp carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions(排放)-71 percent of which are produced by just 100 fossil fuel companies.

Yet the international focus on fossil fuels has overshadowed(使......显得不重要) the most powerful and cost-efficient carbon-capture technology the world has yet seen: forests. Recent scientific research confirms that forests and other “natural climate solutions” are absolutely essential in reducing climate change. In fact, natural climate solutions can help us achieve 37 percent of our climate target, even though they currently receive only 2.5 percent of public climate financing.

Forests' power to store carbon dioxide through the simple process of tree growth is staggering:_one tree can even store an average of about 48 pounds of carbon dioxide in one year. Recent research show undamaged forests are capable of storing the same amount of the carbon dioxide emissions of entire countries such as Peru and Colombia.

For this reason, policy makers and business leaders must create and strengthen ambitious policies to prevent deforestation, and support the sustainable management of standing forests in the fight against climate change. Protecting the world's forests ensures they can continue to provide essential functions aside from climate stability, including producing oxygen, filtering water and supporting biodiversity. Not only do all the world's people depend on forests to provide clean air, clean water，oxygen, and medicines, but 1.6 billion people rely on them directly for their livelihoods.

1.According to the passage, climate change ________.

A. will surely achieve at a scale that is more serious than ever before

B. will only affect people living in the poorest rural regions

C. is likely to lead to more frequent extreme weather events

D. is entirely determined by fossil fuel consumption

2.What's the finding of the new research?

A. Reducing fossil fuels is the most powerful and cost-efficient technology.

B. Forests are vital to reducing climate change due to their storage power.

C. Most of our climate targets can be accomplished with the help of natural climate solutions.

D. Natural climate solutions have proved less efficient than conventional solutions.

3.The underlined word “staggering” in Paragraph 4 means ________.

A. astonishing    B. speeding    C. embarrassing    D. shrinking

4.What's the author's purpose of writing this article?

A. To compare two different approaches to dealing with climate change.

B. To argue against the view that focus on fossil fuels reduction counts.

C. To urge scientists to do more research into natural climate solutions.

D. To point out forests are the most powerful weapon for fighting climate change.

We've all heard the saying: practice makes prefect! In other words, acquiring skills takes time and effort. But how exactly does one go about learning a complex subject such as tennis, calculus, or even how to play the violin? An age-old answer is: practice one skill at a time. A beginning pianist might rehearse scales(音阶) before chords(和弦). A young tennis player practices the forehand before the backhand. Learning researchers call this “blocking”， and because it is common and easy to schedule, blocking is dominant in schools, training programs, and other settings.

However another strategy promises improved results. Enter “interleaving”， a largely unheard-of technique that is catching the attention of  cognitive(认知) psychologists and neuroscientists. Blocking involves practicing one skill at a time before the next (for example, “skill A” before “skill B” and so on, forming the pattern “AAABBBCCC”), while in interleaving one mixes practice on several related skills together (forming for example the pattern “ABCABCABC”).

Over the past four decades, a small but growing body of research has found that interleaving often outperforms blocking for a variety of subjects, including sports and category learning. Yet there have been almost no studies of the technique in unplanned, real world settings-until recently. New research in schools finds that interleaving produces dramatic and long-lasting benefits for an essential skill: math. Not only does this finding have the potential to transform how math is taught, it may also change how people learn more generally.

Researches are now working to understand why interleaving produces such impressive results. One important explanation is that it improves the brain's ability to tell apart between concepts. With blocking, once you know what solution to use, or movement to do, the hard part is over. With interleaving, each practice attempt is different from the last, so rote(死记硬背) responses don't work. Instead, your brain must continuously focus on searching for different solutions. That process can improve your ability to learn critical features of skills and concepts, which then better enables you to select and produce the correct response.

A second explanation is that interleaving strengthens memory associations. With blocking, a single strategy，temporarily held in short-term memory, is sufficient. That's not the case with interleaving-the correct solution changes from one practice attempt to the next. As a result, your brain is continually engaged at regaining different responses and bringing them into short-term memory. Repeating that process can strengthen neural connections between different tasks and correct responses, which improves learning.

Both of these accounts imply that increased effort during training, either to discriminate correct responses or to strengthen them, is needed when interleaving is used. This corresponds to a potential drawback of the technique, namely that the learning process often feels more gradual and difficult in the beginning. However, that added effort can have better, longer-lasting results.

1.What can we learn from the new strategy of “interleaving”？

A. Studying related skills together has many impressive results.

B. Learning relevant skills together contributes to people mastering skills quickly.

C. Focusing on different skills at a time saves people time and efforts in the beginning.

D. Mixing up skills distracts people's attention, thus lessening efficiency.

2.Why does interleaving produce impressive results?

A. It can be scheduled easily.

B. It focuses on rote responses.

C. It is temporarily held in short-term memory.

D. It enables you to learn critical features of skills and concepts.

3.What does the passage mainly talk about?

A. Blocking involves practicing one skill at a time before the next.

B. Correct solution often changes from one practice attempt to the next.
