【推荐1】Teens are really good at ignoring（忽视）their parents’ messages, which is why Nick Herbert, a father from London, created an app called ReplyASAP.

Nick came up with the idea for ReplyASAP after realizing that simply giving his son a mobile phone didn't make getting in touch with him easier. He wasn’t answering Nick's messages as fast as Nick had expected. It was driving the father crazy, so he set out to create a messaging app that would make reaching kids easier for parents. It took eight months and a lot of money to complete the project, but Nick thinks ReplyASAP could really take off, as it is likely to give parents some peace of mind.

ReplyASAP is designed with parents in mind. It lets them know if their child has seen their message,or if their phone is turned off. However, most importantly, it makes it impossible for kids to ignore messages. When they receive a text from their parents, the app basically locks their phone, taking over the home screen and sounding an alarm until the message is answered.

It seems that ReplyASAP will become teenagers’ biggest nightmare（噩梦）, by making it impossible to ignore their parents. Nick agrees that it’s a possibility, but adds that his app shouldn't be parents' most important way of communicating with their children.

ReplyASAP is free to download(下载),but offers a series of plans, depending on how many people you are planning to get in touch with. It works only on Android now. But that's only a short-term shortcoming(缺点), as Nick wants to make ReplyASAP be found on the Apple Store as soon as possible.

【推荐2】It is becoming more and more important for researchers to closely observe our sea life, with climate change and overfishing damaging our oceans. However, this is almost impossible since human presence scares the animals.

Now, thanks to The Soft Robotic Fish, also called SoFi, researchers may not only be able to keep a close eye on the creatures, but also uncover undersea secrets that have been confusing us for centuries. Though not the first autonomous underwater vehicle (AUV) created to observe the oceans, SoFi solves many of the problems that have hindered (妨碍) the usefulness of previous robots.

AUVs traditionally have had to be tied to a boat because radio communications do not work well underwater. To solve the problem, CSAIL director Daniela Rus and her team used sound waves which can travel greater distances, allowing drivers using a waterproofed Super Nintendo controller to pilot SoFi from up to 50 feet away. To ensure SoFi can freely move around the ocean, a pump moves water from one balloon-like structure to the other through its soft rubber tail, while a controller fitted with a battery powers the robot through the ocean.

During test dives, SoFi moved alongside the sea life at depths of 50 feet for up to 40 minutes at a time, taking high-quality photos and videos. Even more importantly, it was able to do so without causing any disturbance. The researchers say sometimes the fish would swim alongside the strange-looking robot-fish out of curiosity, while at other times they appeared completely unaware of its existence.

While SoFi currently only records videos, future versions will include sensors. “For us, this fish is magical,” says Rus. “We imagine someday it might help us uncover more mysteries from the amazing underwater world that we know so little about.”

1. The first paragraph is used to _________.

A．attract readers’ attention

B．provide background information

C．call on people to stop overfishing

D．show human influence on sea animals

2. What drives SoFi to move underwater?

A．A solar battery	B．A rubber tail
C．A special controller	D．An inside balloon

3. What words may be used to describe SoFi?

B．Scary-looking but sensitive.

C．Fast -moving and disturbing.

D．Silent-running but powerful.

4. What can be inferred from the last paragraph?

A．Rus has a magical fish.

B．SoFi needs to be improved.

C．Rus has designed sensors for SoFi.

D．We know little about the underwater world.

【推荐3】In today’s world of cellphones，mini laptops and MP3 players, most people have at least one time-telling tool with them. Since these devices are so common，is time running out for the 500­year­old watch？According to some consumers，yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function”．Many young adults agree—and use their cellphones to tell time. Louis Galie, a senior vice president at Timex，said that fewer young people wear watches today than five years ago. As a result, some people claim that ___________________.
However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s.By then，they are willing to spend money on a quality timepiece that doesn’t just keep good time. Fifty years ago，watchmakers   boasted about their products’ accuracy. But in recent years, the watch industry has transformed itself into an accessory   business. And for many today, the image a watch communicates has become more important than the time it tells.
“Complications”—features that go beyond simple timekeeping—are an important part of a watch’s image. Today’s   watches offer a lot of features that suit almost any personality. These features include altitude trackers, compasses，lunar calendars, USB drives, and even devices that measure the   effectiveness of golf swings!
Creativity is also a key element in today’s watches. For example，Japanese watchmaker Tokyoflash makes watches that don’t even look like watches. The company’s popular Shinshoku model uses different color lights to tell time. It looks more like a futuristic(未来主义的)bracelet than a watch. Another Japanese watchmaker, EleeNo, makes a “handless” watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece.
Whether a watch communicates fashion sense, creative talent or a love of sports, consumers want their timepieces to stand out. Nowadays，everyone has the same kind of gadget (小玩意儿)in their bags，so people want to make a statement with what’s on their wrists. Will this interesting wrist fashion last？Only time will tell!
1. Why aren’t watches popular with young people as before?

A．Because watches cannot keep good time as cellphones, mini laptops and MP3 players.

B．Because watches are featured by the disadvantages of simple function.

C．Because watches are too expensive to afford.

D．Because watches don’t have beautiful appearance as other modern time­telling tools.

2. What does the underlined sentence in Paragraph 1 mean?

A．Watch­making is facing a survival crisis challenge.

B．Watch­making is faced with the developing opportunity.

C．Watch­making becomes the sunrise industry.

D．Watch­making has a specific development target.

3. It can be implied that ________.

A．people will gradually lose interest in watches as they grow older

B．watchmakers scarcely change the development strategy for watches

C．today’s watches are better than those in the past in quality

D．customers used to be more concerned with the quality of a watch than with its image

4. What’s the best title of the passage?

A．Watches and Teenagers	B．The History of Watches
C．The Accuracy of Watches	D．Watches Tell More than Time

【推荐1】Do you often compare yourself to other people? Comparisons can help to make decisions and motivate you but they can also pull you into a comparison trap.

Whether it’s the number of goals you’ve scored at football or how many books you’ve read, it’s easy to compare yourself to someone else. Scientists say it’s a natural behaviour that helps humans learn from each other, live happily together and achieve more. Although comparing can be good for you, it’s not always helpful and you can find yourself stuck in a comparison trap. This is when you always measure yourself against others and base your feelings on how well others seem to be doing.

Becky Goddard-Hill is a child psychologist and author of Create Your Own Confidence. She says that comparisons can make us feel good and bad about ourselves. “Comparing up” means seeing someone doing better than you and using that to inspire yourself to aim higher and try harder. However, Goddard-Hill says, “Sometimes it can make you feel rubbish about yourself and knock your confidence.” “Comparing down” is when you see someone who seems like they’re not doing as well as you. This might make you feel you’re doing well, says Goddard-Hill, but it can also stop you wanting to improve.

“If your feelings depend on what other people are doing, surround yourself with cheerleaders,” suggests Goddard-Hill. Notice how people make you feel and spend time with friends who celebrate your strengths rather than compare themselves to you.

If you follow social media accounts that make you feel you are failing in any way, unfollow them. “Find ones that make you laugh or show you lovely places instead,” she says. Finally, focus on your own achievements and how you can improve. “The best person you can compete with is yourself,” says Goddard-Hill.

1. How does a comparison trap affect us?

A．It helps us focus on our own behaviour.

B．It stops us from learning from each other.

C．It prevents us from living happily together.

D．It makes us care little about our true feelings.

2. What’s true about “Comparing up” and “Comparing down”?

A．The latter may encourage us to appreciate others.

B．The former may help us try harder and gain confidence.

C．The latter may fail to help us make self-improvement.

D．The former may stop us from learning from role models.

3. What does Goddard-Hill suggest?

A．Aiming to be our best.

B．Trying to be the best.

C．Trying to be a cheerleader.

D．Valuing others’ achievements.

4. In which section of the magazine can you find the passage?

A．Politics.

B．Health.

C．Science.

D．Entertainment.

【推荐2】Over the past few months huge groups of locusts(蝗虫), one of which occupied an area more than three times the size of New York City, have eaten up crops across the Home of Africa and the Middle East, leaving an estimated 20 million people at risk of famine(饥荒). The first generation's eggs are starting to hatch, and now even bigger swarms(虫群) are forming threatening. Countries from the Democratic Republic of Congo to Yemen, Iran, Pakistan and India, “representing a threat to food security and livelihoods,” says the U.N.'s Food and Agriculture Organization(FAO).

Desert locusts' populations explode when weather conditions are right. That explosion can create huge swarms that can travel great distance-more than 90 miles in a day-in search of food. Warm weather and unusually heavy rains in the Horn of Africa at the end of 2019 provided the moist(湿润的) soil necessary for hatching eggs. From there, the insects spread rapidly, resulting in one of the worst outbreaks the region has seen in more than 70 years.

A typical swarm numbering 4 billion to 8 billion locusts, can consume in one day the same   amount of food as 35 million people. Some swarms have been so thick in parts of Kenya that they have prevented planes from taking off. Governments have used widespread aerial spraying of pesticides when available; in poorer regions, where aircraft are unavailable, soldiers battle the swarms with handheld spray pump.

The FAO has appealed for $138 million to support affected communities, If the locusts are not stopped before the next generation hatches, the impact could be terrible: the FAO guesses that an additional 25 million people across the region could lose their crops. Scientists in Kenya hope a new computer-assisted tracking program that combines satellite data with weather-mapping software will help predict the swarms next destination, buying-regional authorities enough time to prepare a response. Buy coronavirus- related travel restriction have delayed relief efforts as well as response mechanisms. The locusts have no such travel limitations.

1. The author uses many statistics in the passage to show_____

A．the disastrous consequence of the outbreaks of locusts

B．the serious conditions facing the New York City

C．the speed of swarms of locusts travelling

D．the exact number of crops consumed by locusts

2. What is Paragraph 2 mainly about?

A．The great distances locusts can travel.

B．The explosion of locusts' population.

C．The perfect conditions for hatching their eggs.

D．The result of the unusual outbreaks of locusts.

3. What does the last paragraph imply?

A．The travel restrictions may probably worsen the urgent situation.

B．It is unlikely to predict the swarms' next destination now.

C．A lot of money has been raised after the FAO's appeal

D．It's not difficult for humans to win the battle against the locust

【推荐1】＂Did you hear what happened to Adam last Friday?＂ Lindsey whispers to Tori.

With her eyes shining, Tori brags, ＂You bet I did. Sean told me two days ago.＂

Who are Lindsey and Tori talking about? It just happens to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren’t very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.

An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic — breakups, trouble at home, even dropping out — that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.

If we know that gossip can be harmful, then why do so many of us do it? The answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor(传言) can make a person feel important because he or she knows something that others don’t. Similarly, hearing the latest rumor can make a person feel like part of the ＂in group.＂ In other words, gossip is satisfying because it gives people a sense of belonging or even superiority(优越感).

Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do’s and don’ts conveyed through gossip will never show up in any student handbook.

The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, think about why you want to gossip and what effects your ＂juicy story＂ might have.

【推荐3】On the night of June seventeenth, happily unaware that I was now less than forty-eight hours from my little “date” with Bryan Smith, I sat down at our dining room table and listed all the questions I wanted to answer, all the points I wanted to address in my book On Writing-A Memoir of the Craft. On the eighteenth, I wrote the first four pages of the “On Writing” section. That was where my writing still stood in late July, when I decided I'd better get back to work... or at least try.

My wife Tabby is the person in my life who's most likely to say I'm working too hard, it's time to slow down, stay away from that disgusting PowerBook for a little while. When I told her on that July morning that I thought I'd better go back to work, I expected a lecture. Instead, she asked me where I wanted to set up.

She thought about it, and said: "I can lay a table for you in the back hall. There are plenty of plugins so you can have your laptop, the little printer, and a fan. "A couple of hours later, she had made me a wonderful little nest there: laptop and printer, my notes, pens, and reference materials...Standing on the corner of the desk was a framed picture of our younger son, which she had taken earlier that summer.

“Is it all right?” she asked.

“It's wonderful,” I said, and hugged her. It was wonderful. So is she.

That first writing session lasted an hour and forty minutes, by far the longest period I'd spent sitting upright since being struck by Bryan Smith's car. When it was over, I was sweating and almost too tired to sit up straight in my wheelchair. And the first five hundred words were uniquely terrifying--it was as if I'd never written anything before them in my life. All my old tricks seemed to have deserted me. I stepped from one word to the next like a very old man finding his way across a stream on a winding line of wet stones. There was no inspiration that first afternoon, only a kind of stubborn determination and the hope that things would get better I kept at it.

There was no breakthrough that afternoon, unless it was the ordinary miracle that comes with any attempt to create something. All I know is that the words started coming a little faster after a while, then a little faster still. My back still hurt, my leg, too, but those hurts began to seem a little farther away. I started to get on top of them. There was no sense of excitement- not that day-but there was a sense of accomplishment that was almost as good.

After that,things can only get better.

【推荐1】My old professor’s death sentence came in the summer of 1994. Doctors guessed he had two years left. Morrie knew it was less. But he had made a big decision, one he began to construct the day he came out of the doctor’s office with a sword hanging over his head. He would make death his final project. Since everyone was going to die, he could be of great value, right? He could be researched. Morrie would walk that final bridge between life and death, and record the trip.

The last class of my old professor’s life had only one student. I was the student. The class met on Tuesdays. The subject was “The Meaning of life”. It was taught from experience. No grades were given, but there were oral exams each week. You were expected to respond to questions, and you were expected to raise questions of your own. You were also required to perform physical tasks now and then, such as lifting the professor’s head to a comfortable spot on the pillow or placing his glasses on the bridge of his nose. Kissing him goodbye earned you extra credits. No books were required, yet many topics were covered, including love, work, community, family, aging, forgiveness, and finally, death.

I look back sometimes at the person I was before I rediscovered my old professor. I want to talk to that person. I want to tell him to be more open, to pay attention when your loved ones are speaking, as if it were the last time you might hear them. None of us can undo what we’ve done, or relive a life already recorded. But if Morrie taught me anything at all, it was this: there is no such thing as “too late” in life. He was changing until the day he said goodbye.

【推荐2】For the past 3000 years, when people thought of money, they thought of cash. From buying food   to settling bar bills, day-to-day dealings involved paper or clinking bits of metal. Over the past decade, however, digital payments have taken off — tapping your credit card on a terminal or using a smart phone has become normal. Now this revolution is about to turn cash into an endangered species in some rich economies. That will make the economy more efficient, but it also poses new problems that could make the change victim.

Countries are eliminating(消除) cash at varying speeds. But the direction of travel is clear, and in some cases the journey is nearly complete. In Sweden the number of retail cash transactions per person has fallen by 80% in the past ten years. Cash accounts for just 6% of purchases by value in Norway. Britain is probably four or six years behind the Nordic countries. America is perhaps a decade behind. Outside the rich world, cash is still king. But even there its dominance is being weakened. In China, digital payments rose from 4% of all payments in 2012 to 84% in 2020.

Cash is dying out because of two forces. One is demand — younger consumers want payment systems that plug seamlessly(无缝地) into their digital lives. But equally important, suppliers such as banks and tech firms (in developed markets) and telecoms companies (in emerging ones) are developing fast, easy-to-use payment technologies from which they can pull data and pocket fees.

In general, the outlook of a cashless economy is excellent news. Cash is inefficient. In rich countries, minting, sorting, storing and distributing it is estimated to cost about 0.5% of GDP. But that does not begin to capture the gains. When payments disappear, people and shops are less   fragile to theft. Governments can keep a closer eye on fraud or illegal tax avoidance. Digitalization vastly expands the playground of small businesses and sole traders by enabling them to sell beyond their borders. It also creates a credit history, helping consumers borrow.

1. What is the purpose of Paragraph 1?

A．To show the background of using cash.	B．To introduce the main topic of the text.
C．To present the development of cash.	D．To explain the history of digital payments.

2. Which of the following statement is true according to the passage?

A．Sweden has already completely eliminated cash.

B．Digital payments have replaced cash in rich countries.

C．Britain develops faster than China in digital payments.

D．Both developed and developing countries are using cash less.

3. What is Paragraph 3 mainly about?

A．The ways of digital payments.	B．The effects of cash dying out.
C．The reasons for cash being endangered.	D．The importance of digital payments.

4. What is the author’s attitude towards the future of cashless economy?

A．Ambiguous.

B．Optimistic.

D．Disapproving.

【推荐3】Samuel L. Clemens, also known as Mark Twain, started off his writing career (事业) in 1865 with his big hit story The Celebrated Jumping Frog of Calaveras County — a story-within- a-story told to a listener by an old California miner. From that day on, the works of the great humorist always had different animals.

Some members of Twain’s literary (文学的) animals were based on real animals, such as the Clemens family’s named pet cats. Some were imaginary, like that celebrated jumping frog.

As a boy in Missouri, he got pleasure from knowing the animals of the woods; in old age,   he felt a deep relationship with the animals large and small that he met in his travels. His cats, family dog, horses, donkeys, and calf also won his three daughters’ love at their Hartford home. On March 22, 2018, to mark this part of Twain’s personal life, The Mark Twain House & Museum opened a new exhibition (展览), Tails of Twain: How Animals Shaped the Man & His Work. The exhibition was rich with exhibits from the museum’s collections.

The king of the animals in Twain’s world was the cat, “the only creature in heaven or earth or anywhere that don’t have to obey (听从) somebody or other, including the angels.” He was known to be the proud pet parent of 19 cats during his childhood. As an adult, the Clemens   home always had a named cat. Even on vacation, the Clemens family borrowed cats from locals to live with them. Dogs were considered second-class pets, but Twain liked them. Twain once wrote an ode (颂诗) to his dead dog Burns: “She lived a quiet harmless life in Hartford ...”

In true Twainism, humans were not as loved as the “Higher Animals”. Even the most low- down animal, however, was superior in Twain’s eyes to “the human race.” After all, he did write once “Of all the animals, man is the only one that is cruel.”

1. What can we learn about The Celebrated Jumping Frog of Calaveras County?

A．It tells a story of Twain’s family pet.

B．It was written for Twain’s three daughters.

C．It made Twain pay attention to animals.

D．It was Twain’s first great success as a writer.
