1 . One day, Amanda was diagnosed (诊断) with cancer of an early stage. During this time, she was admitted to a college. She planned to save money to meet the college expense and then seek medical treatment for the cancer.
Her father, Clint and her friends didn’t want her to put off her treatment due to the expense. They took matters into their own hands and started a GoFundMe campaign. A longtime friend of the family was cofounder of a group named Praynksters, known for random acts of kindness. The friend decided to use their own group to help the family. The group came up with the creative idea to spread the word and invite families, friends, and strangers who wanted to help to take part in a donation activity. The event induced the enormous assistance from the local community.
Clint and Amanda were moved as the crowd passed by and the donations poured in. The event brought the family over $13, 000 in donations to go towards her medical treatments. The generous act of kindness gave the family a comforting, and optimistic feeling during a time when all hope seemed lost. Clint said that Amanda struggled with the idea of asking for help. She felt guilty and undeserving compared to others who are also struggling. She is still humbled by it all.
After several months of treatment, life for the family has started getting back to their normal routine. Once Amanda got her strength back, she returned to school and completed her bachelor's degree. The family is now inspired to volunteer in their local neighborhood and contribute to crowdfunding (众筹) efforts. They are grateful for the opportunity to give back and help others as many have helped them.

2 . Most of us marry creativity to our concept of self either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a frustrated student might say in art class, while another might blame her talent at painting for her difficulties in math, giving a comment such as, "I'm very right-brained."
Dr. Pillay, a tech entrepreneur and an assistant professor at Harvard University, has been challenging these ideas. He believes that the key to unlocking your creative potential is to ignore the traditional advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.
Dr. Pillay points to a 2016 study demonstrating the impact of stereotypes on one's behavior; The authors. educational psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into three groups, instructing the members of one to think of themselves as "romantic poets" and the members of another to imagine they were "serious librarians" (the third group was the control). The researchers then presented all the participants with ten ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. Those who were asked to imagine themselves as romantic poets came up with the widest range of ideas, whereas those in the serious-librarian group had the fewest. Meanwhile, the researchers found only small differences in students' creativity levels across academic majors.
These results suggest that creativity is not a fixed individual characteristic but a "malleable product of context and perspective, as long as he or she feels like a creative person. Dr. Pillay argues that, besides identifying yourself as creative, taking the bold, creative step of imagining you are somebody else is even more powerful. So, wish you were more creative? Just pretend!

| C．right brain determines whether a person is creative or not |
| D．if we pretend to be creative， then we might be really creative |
3 . Teachers say that the digital age has had a good influence and a not-so-good influence on American teenagers. More than 2,000 middle school teachers took an online survey. Researchers also spoke with teachers in some groups. Most teachers think the Internet and digital search tools have had a mostly positive (积极的) influence on their students’ research habits and skills. But at the same time, some teachers also point out some problems in teenagers’ using digital search tools.
The Pew Internet Project did the survey with the College Board and the National Writing Project. Judy Buchanan is the director of the National Writing Project and a co-writer of the report. She says digital search tools are helping students learn more, and learn faster. “Both teachers and students really welcome these tools because they make learning exciting. And the goal（目的）is to really help students become creators of something meaningful, and not just users of the online information.”
But one problem the survey found is that these technologies make teenagers have short attention spans (持续时间). As there is lots of information about different subjects on the Internet, teenagers’ attention is easily drawn away from their research.
Another problem the survey found is that many students trust the information they find on the Internet too much. Judy Buchanan says these students have not developed the skills to judge (判断) the online information. They need to learn a lot to tell if the information is believable. It’s something that really has to be paid attention to.
One more problem the survey found is something that might not seem like a problem at all: being able to quickly find information online. Many students think “doing research” now means just doing a quick search on Google. Teachers say the result is a drop in the wish and ability of their students to work hard to find answers. That is, they are depending too much on search engines and do not make enough use of printed books or research librarians.
Many teachers also say that the Internet makes it easy for students to copy work done by others instead of using their own abilities.
1. The result of the survey shows ________.| A．digital search tools need to be greatly improved |
| B．digital search tools are generally good for teenagers |
| C．teenagers have difficulty in using digital search tools |

4 . Coffee chains create a lot of waste, from disposable take-away cups to the used grounds that are sent to landfills. Starbucks has started to try recyclable alternatives to the disposable cups. But the used coffee is often unnoted.
The world drinks around 2 billion cups of coffee a day, producing 6 million tons of used grounds every year. When they go to landfills, the grounds release greenhouse gases into the atmosphere, contributing to global warming.
UK Bio-bean has found a way to turn that waste into a valuable resource. At Bio-bean, used coffee grounds are processed to remove paper cups or plastic bags, and then passed through a dryer and a further screening process. They are finally processed into the fuel. Coffee Log.
"Coffee is highly calorific and lends itself to being a really fantastic fuel," says May. director of Bio-bean. "They burn about 20% hotter and 20% longer than wood logs do."
While these fuels release greenhouse gases when burned, if they replace other carbon-based fuels. Bio-bean estimates that the recycling process reduces emissions （排放）by 80% compared with sending the grounds to landfills.
Founded in 2013 Bio-bean grew rapidly, launching coffee collection services across the UK and building the world's first coffee recycling factory only two years later. In 2016 they launched their first product, Coffee Log, and are now ready to launch their first natural flavouring ingredient into the food and drink industry.
“We've really managed to succeed with our innovation because we've managed to get to scale. What started as a good idea is today the UK's largest recycler of coffee grounds. We are turning 7,000 tons of those grounds per year into the fuel," says George May. "Despite being delayed by the COVID-19, we plan to expand our operation into northwestern Europe within the next five years."
1. What do the first two paragraphs suggest?| A．It’s necessary to limit coffee consumption. |

5 . 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.

6 . Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere, and so raising the temperature of the earth.
In Europe, eight of the last ten years have seen record high temperatures. On the other hand, the countries around the Mediterranean Sea are receiving even less rain than before. In Sub- Saharan Africa the crops are drying out in the fields and people are dying of starvation. In 1999, the southern United States was struck by a serious of destructive(毁灭性的) hurricanes. Scientists expect such trends to continue, and to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and extreme weather conditions, scientists are closely monitoring sea levels around the world. They are slowly rising, as the northern and southern polar ice caps start to melt. This will have serious consequences for low-lying countries near the sea. Already parts of these places are disappearing under the rising sea water.
According to a new research, one contradictory feature(特征) of global warming is that it will probably lead to a period of much colder weather. Scientists base their theory on what happened the last time the world warmed up, 8,300 years ago. They have discovered that when the ice melted from the northern polar ice cap it became trapped in a lake in northern Canada. As more ice melted, this lake suddenly burst open, pouring millions of tons of freezing fresh water into the North Atlantic. This flood of water prevented the normal flow of water in the Atlantic, which takes warm water from the tropics(热带地区) north to Europe. When this flow of warm water was cut off, temperatures in Europe dropped by between three and eight degrees over the next 200 years. ''That's the concern here,'' says Richard Alley, an American climate expert. ''The climate hasn't varied much in 8, 000 years. But big changes could come back!''

| C．Global warming will continue for the next two centuries. |
| D．Global climate will remain unchangeable in the next 8,000 years. |
7 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.
1. Why does the author compare the parent-teen war to a border conflict?| A．Both are about where to draw the line. |
| B．Both can continue for generations. |
| C．Neither has any clear winner. |

| D．The teens blame their parents for starting the conflict. |
| A．give orders to the other |
| B．know more than the other |
| C．gain respect from the other |
| D．get the other to behave properly |

8 . Deep in the middle of Sri Lanka, a massive column of rock reaches out from the green tropical forest. It is 660 feet tall and features frescoes (壁画), graffiti, and landscaped gardens.
The rock is known as Sigiriya and holds a special place in the island's cultural history.
It was established as the stronghold of a king over 1,500 years ago, and today the Sigiriya complex stands as one of the earliest preserved examples of ancient urban planning.
Located in the Central Province, the column of rock is somewhat central to the country. The rock is known as Sihagiri, meaning "Lion Rock", a nod to the giant animal carved from stone which greeted visitors at the entrance.
In 476 BC. King Dhatusena ruled over Sri Lanka. One of his illegal sons, Kashyapa, wanted the throne (王位). Kashyapa overthrew Dhatusena and drove his brother Moggallana to Southern India. Kashyapa crowned himself king in 477 BC.
King Kashyapa chose Sigiriya as his palace because its position was an advantage to the defensive stronghold, offering fantastic 360-degree views. Plans to build a city quickly unfolded and after several years, the Sigiriya complex had become a business center for the new King.
Sigiriya was both a palace and a fortress (堡垒); the overall complex featured five gates and measured just under 3 km by just over 1 km. The site plan consisted of a fort，an upper palace on the top of the rock,and lower palaces at ground level. The king also constructed gardens throughout，and for protection a river with walls surrounded the complex.
Frescoes decorate the western side of the rock, along with the mirror wall, a brick face covered in a highly-polished white plaster. When new, the wall was said to be able to produce Reflections.
Over time the Mirror Wall became a graffiti board, covered in verses written by visitors. Known as "Sigiri Graffiti", some of the messages date to the 8th century CE.

9 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

10 . Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.
This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.
According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.
At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.
What do you think? Would you like to see everyone accessing high-detail live maps of the Earth's surface? Please share your idea with us on the website.
