1 . The world can be a scary place when you' re young. It can be even scarier when you' re a young little blue penguin(企鹅) , the tiniest of the penguin species. Luckily, there are some humans willing to help. They stepped in to protect Billy, a blue penguin that appeared on a beach in Christchurch, New Zealand.
Spotted on November 29 at the slipway at Moncks Bay, near Sumner，in Christchurch，the little penguin immediately attracted a small crowd. Jeff Mein Smith saw the crowd while he was bicycling that afternoon, and he biked home to get his camera. When he returned to the scene，he found that the penguin had received a little sign, one that read “Hi, I'm waiting for my mum to come back. DOC(Department of Conservation) knows I'm here. Please leave me alone. Keep your dog away. Thanks, Billy the baby blue penguin.”
Billy didn't move away from the sign. The DOC arrived later that afternoon to pick up Billy, though they were surprised to see it on the beach. “It's unusual for a blue penguin to be out in the open on the beach during the day, ”Anita Spencer, a DOC senior ranger, told Stuff.
Billy was taken to the Christchurch Penguin Rehabilitation Center after being retrieved from the beach. Volunteers believe the bird may actually be a female penguin, and is around 2 months old. The chick weighs a mere 550 grams, less than a standard basketball. A blue penguin should weigh around 900 grams at this age. Most little penguins grow up to weigh 1 kilogram.
The center will help the little penguin gain some weight by feeding it fish juice, before it's set free into the ocean.

2 . We recognize our friends’ faces. And we’re not alone. Many social animals can identify individuals of their own species by features of their faces. That's important, because they need to be able to change their behavior depending on who they meet. And a recent research has shown that some species of monkeys, birds, and domesticated (家养的) animals can even tell different faces apart by looking at photographs alone.
Ethologist Léa Lansade of the French National Research Institute for Agriculture, Food and Environment did an experiment to find out how well horses can recognize individual people in photographs.
She and her team first taught the horses how to “choose” between two side-by-side pictures by touching their noses to a computer screen. The horses were then shown photos of their present keeper alongside faces of unfamiliar humans. They had never seen photos of any of the people before. The horses correctly identified their current keeper and ignored (忽视) the stranger’s face about 75%of the time. In fact, even though the horses didn't get it right every single time, they were at least as correct in picking out their earlier keeper as they were at identifying their present one.
The results suggest that not only can horses differentiate between familiar and unfamiliar human faces, they also naturally understand that photographs are two dimensional representations (二维呈现) of real life, without any other intimations such as smell or sound. And they’re even better at this than our oldest animal parter, the domestic dog.
In addition, horses seem to have a strong long-term memory for human faces, like their long lifespan and history of domestication. In future experiments, the researchers would like to test whether looking at photos of people that they have had bad experiences with in the past might cause horses to act anxious or even avoidance. So maybe think twice before doing anything that might give a horse a long face.

3 . Recently I read Nineteen Eighty-Four, a novel by George Orwell set in a state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as ‘ungood’, ‘plus good’ and ‘double plus good’ to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it’s already happening. I type messages to my friends and alongside each is the emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our excessive use of emojis, are we losing the beauty and diversity of our vocabulary?
English has the largest vocabulary in the world, with over one million words, but who’s to say what it’ll be like in the future? Perhaps we will have a shorter language, full of saying ‘cry face’ if something sad happens or using abbreviations (缩写) like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began – the new language? Or is this a classic case of the older generations saying, ‘Things weren’t like that when I was younger. We didn’t use emoticons to show our emotions’?
Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what’s even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to transcend time and language. Images, be it cave paintings or emojis, allow us to convey a message that’s not restrictive but rather universal.

4 . As new technology is introduced, there are many who worry about its influence on our current and future lifestyles－particularly when it comes to jobs. It is a current belief that with the rise of automation and artificial intelligence (AI), many people’s jobs, and therefore their livelihoods, are likely to be lost.
Automation in the workplace is nothing new. Machines have been performing dull tasks on our behalf for years, allowing us to escape many repetitive jobs. A recent report from the McKinsey Global Institute states that nearly two thirds of all jobs could have at least 30% of their activities automated by 2030. However, McKinsey also believes that this new technology will also ‘create new occupations that do not exist today, much as technologies in the past have done.’ As the horse gave way to the car, hostlers (马夫) became mechanics and mechanised fields drove up wages and created more long-term roles than it destroyed.
“It’s an evolution of work,” says Ian Barkin, a robotic process automation specialist. As low-skilled jobs are taken on by AI, people will need to learn new skills. “This calls on us to focus on up-skilling. Technology can lead to job reductions but it doesn’t have to,” says Barkin.
Whether or not robots and AI will leave us all jobless remains to be seen. Current views on the subject are mixed. Increased automation could indeed lead to a loss of some jobs, but at the same time is likely to create many more as new skills are required. Will they balance out?

5 . Grandma was going to turn eighty-two on Friday. I heard Mom ordering a cake from the bakery over the phone. “Don’t put any icing on it,” she said, “Just a plain angel cake.” Angel cake with fresh strawberries was her favorite. So Mum was ready.
That afternoon when Dad came home, he showed me the phone he had bought for Grandma. “It has speed-dialing,” he said. “She won’t have to push so many buttons when she calls the doctor’s office or her sister.” Dad looked pleased. “Her fingers are so stiff with arthritis (关节炎) that the phone seems a good idea.”
But what about me? Here I was with only one dollar in my pocket and one night to think of a gift. Even though Mom always insisted that “it’s the thought that counts,” I had a big problem. My mind was even more empty of ideas than my wallet was empty of money.
When I have a problem, it sometimes helps to shoot a few baskets in the driveway. Dribble, shoot, rebound.
For a while I just played without even trying to think. I began to remember back before Granddad died, when we used to visit them in Kentucky, Granddad showed me how to do a jump shot. Thinking about Granddad made me sigh. Grandma’s life was a lot happier when he was alive.
Swish! I’d made two in a row.
Suddenly, I remembered a green glass dish in the shape of a leaf that Grandma used to keep on a table back in Kentucky. It was always full of those red-and-white-striped peppermint candies. I hadn’t thought of that dish for a long time. Maybe it was lost or broken when Dad rented the truck and brought Grandma and the belongings to Ohio.
Just thinking about that candy dish made me taste the peppermint slowly dissolving on my tongue. I could almost hear Grandma saying，“Help yourself to a piece of peppermint, Burt.” That voice had a smile behind it. It was a voice I hadn’t heard for a long time.
Aha! I took one last shot, then dribbled to the back door, ran up the steps two at a time, and grabbed my wallet.

6 . I looked at my beautiful Christmas tree and sighed.It was time.The New Year was a week old and my tree still stood in the corner of our room with its collection of memories proudly displayed in a shower of colorful lights.I’d procrastinated long enough.
I got up, went to the garage and dragged all the boxes into the room.The garland (花环) was the first to come down.The tree looked naked (光秃秃的) already.I took the large ornaments off next.They made a large pile on our bed.An hour later, our bed was covered with Christmas memories.Each pile contained an ornament along with its matching brothers and sisters from sets purchased many years ago.
I prepared the boxes and carefully placed ornaments in their protective packaging, pausing every few minutes to admire a favorite.“Hey, little Santa!” I held the Santa from my childhood.“Thanks for being my friend for almost 50 years.” He was a little ragged (衣着破烂的) but still gives me a flood of wonderful memories.“Until next year, my dear friend.”
There was a collection of handmade ones.My children made in their first years of school, more than 20 years ago.Made by tiny hands, they are far from perfect in design, but every year they go on my memory tree – memories of young giggles on Christmas morning and a smiling face when they handed them to me when I came home from work.“Look what we made, Daddy!”
“Oh! It is beautiful.Let’s find a special spot on the tree for it.” Every year since, they are displayed.
A few hours after I started, the filled boxes were back in the garage, the room was vacuumed (用吸尘器清扫) and I sat staring at a barren (空荡荡的) corner.The room seemed so empty.It took me two days of work to assemble (收集) and decorate my tree, but only a few hours to take it apart.
My tree is a good marriage or a great friendship.Like the tree, they take a long time to assemble and decorate with memories, but can be torn down quickly.
Every year I have to put my tree away, but not my marriage or friendships.I take great care of those.They get to glow in the corner of my life for as long as I live.I get to analyze my tree and find memories for a few weeks every year.I can do the same with the loves in my life every day.Take great care of your friendships and your marriage.Once they come down, they aren’t as easy to put back together as a Christmas tree.Stand them in that special spot in the corner of your heart and admire their glow.

7 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model thatprojectschanges to the oceans throughout the century. In a world that warms up by 39C, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener.” Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “ but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

8 . Sea urchins (海胆) are small creatures, but what’s really remarkable about them is that they eat anything that happens to float by. They have really sharp teeth they use to rid rocks of algae (海澡), which makes them pretty valuable especially in places like Hawaii where algae are threatening the coral reefs. In the summer of 2019, 500,000 of them were used to deal with the algae.
The problem started when non-native algae were introduced to the ecosystem of Kane’ohe Bay in the 1970s. Because they had no enemies, they ended up taking over the bay, according to the National Marine Fisheries Service (NMFS). The algae blocked sunlight from reaching the coral, which in turn affected the local fish because they changed the chemistry of the water.
That's when the NMFS turned to sea urchins that loved to devour the algae. But they had to grow to the size of a cherry tomato before they could be used. Since 2011, sea urchins have been grown and used to handle the algae problem. Some of the funds are available due to an unfortunate incident.
In 2005, a ship was grounded on a shallow reef near Kane’ohe Bay. When the ship was removed, 20 acres of reefs have been damaged. When there is environmental damage, the NMFS and other agencies receive funds from the wrongdoers and the funds are used to restore the damage. Some funds were spent on other projects like the sea urchins.When they are large enough, divers carefully place them on the reef.
Algae isn’t the only thing that threatens the coral reefs. Climate change and the effects of fishing and tourism in the area also endanger the coral reefs. But turning to sea urchins instead of man-made solutions seems like the best way to go.

9 . GPS has completely transformed how we get around. But other animals have long had their navigation (领航) systems built right in.
“We know their eyes are quite sensitive to polarized (偏振的) light and the sky has a particular pattern of polarized light relative to the position of the sun,” Barbara Webb, a researcher at the University of Edinburgh, says.
You can see polarized light firsthand if you take a pair of polarized sunglasses and spin them against the sky-the light passing through the glasses changes. Webb says the insects have polarization like that built into their many eyes. “You can think of it as having lots of sunglasses pointing in different directions.”
But Webb was curious whether there’s really enough information in the sky to give insects an accurate sense of direction. So her team built a sensor (传感器) modeled after a desert ant eye and put it under artificial light meant to simulate the sky. They then put that sensor into a model meant to model the brains of desert ants and other insects. And they found that with the insects’ sensing and processing equipment, they can likely sense direction down to just a couple degrees of error.
A system based on that of insects could someday be a cheap, low-energy choice to GPS. Insects have very tiny brains. A brain the size of a pinhead that’s using hardly any energy. And yet they’re still able to navigate better than we can with GPS, which is surprising. Webb is now working on building a robot that can use light to get its directions.

10 . Creativity is the ability to generate novel,useful ideas and innovation is the successful application of those ideas.With this in mind,it is easy to think that technology has made us more creative:the digital revolution(改革）has clearly produced a large number of innovative products and services.
However,it would be naive(幼稚的）to imply that these activities are truly indicative of creativity,even if quantity does eventually lead to quality.For instance,the probability of taking a great photograph does increase when there are millions of Instagram pictures taken every day,and when 500 million tweets are generated(严生）daily,it is highly probable that one or two will be funny.
Yet,much of the content people generate is unimportant and unoriginal.Before the Internet it would have stayed in the minds of their authors,but our thoughts can now be broadcasted to the. world as if they were worthy creations.The only thing that appears to have increased,rather greatly,is people's self-perceived(自认为的）creativity.From the use of emoji(表情符号）instead of words,to the use of pre-determined functions to express our views-liking,sharing and disliking,these new forms human interaction promote efficient-but lazy-behaviors so that we can devote more time to consuming more content.
Although user-generated content has been growing rapidly in the past decade,much of it is noise and the result is that valuable and trustworthy information is now harder to find.In an age of information glut(过剩），everything is freely available but knowledge is hard to gain.This paradox highlights the importance of the"less is more"philosophy of life.
Curiosity evolved to make sense of the world and help us master our environments.Our ancestors must have benefited from taking on as much information from their surroundings as they could paying attention to everything and turning into the learning machine.Yet in an age of information glut,the curious mind is forced to ignore as much of the available data as it can,in order to consume only what is valuable.
1. Why are the examples of great pictures and funny tweets mentioned in Paragraph 2?| A．To show quantity will lead to quality. |
| B．To explain creativity is something impressive. |
| C．To show technology hasn't made us more creative. |
| D．To explain innovative products come from creativity. |
| A．They are worthy creations. |
| B．They kill people's creativity actually. |
| C．They prevent effective communication. |
| D．They help people consume more useful content. |
| A．There' re more resources for knowledge but few people are willing to use them. |
| B．Too much information has generated material wealth but not spiritual wealth. |
| C．We live in an age of information explosion but we find it difficult to get knowledge. |
| D．Many people stick to the"less is more"philosophy with large amounts of information at hand. |
| A．Much of it is original information about the real world: |
| B．It is the fruit of our ancestors' mastering our environments.. |
| C．It gives the public quick and easy access to the required information. |
| D．It presents us with the challenge of telling valuable information from worthless content. |
