It took humans thousands of years to understand our own planet, and centuries 1  our neighboring planets. Nowadays, new worlds are being 2  every week. 

Up to the present time, astronomers have 3 more than 370 "exoplanets"—planets orbiting (绕……运动) outer space stars (恒星) other than our sun. There is a "hot Saturn (土星)" 260 light-years from Earth that orbits its parent star so 4 that a year there lasts less than three days. 5 another star 150 light-years out is a burning "hot Jupiter (木星)," where upper atmosphere (大气层) is being burning to form a huge comet-like tail. Astronomers have found another three 6 orbiting a pulsar (脉冲星)—the remains of a once huge star shrinking (收缩) into a small atomic nucleus the 7 of a city. Some planets have obviously fallen into their suns. Others have been thrown out of their 8 to become "floaters" that float in the darkness of the universe.

Among all these, scientists are eager to find a clue of the 9 : planets like the Earth. That is, planets orbiting their stars at just the right distance—neither too hot nor too cold—to 10 life as we know it. We have not yet found planets that are quite like our own, 11 because they're inconspicuous (不起眼的). To see a planet as 12 and slim as ours among the brightness of its star is like trying to see a firefly in a fireworks display. 13 by pushing technology to the 14 , astronomers are rapidly approaching the day when they can find another Earth. And when they do, they can examine it for 15 of life.

Adapted from Liang Xiaosheng's award-winning novel, the realistic drama A Li felong Journey recently has been a huge hit on TV and online.

Given that A Lifelong Journey is set in the 1960s, it's not surprising that the family has to deal with lots of social changes and uncertainties, like the restoration of Gaokao, the country's reform and opening-up, the passion for private business and so on. To create the neighborhood, the shooting crew built a set covering 8, 000 square meters in Changchun, Jilin province, collecting many old items, such as old-fashioned televisions and calendars, to re-create the past. The clothing, like Lei Feng-style hats, and interior spaces, also play an essential part, changing with time as the plot develops.

The five virtues in Confucianism—benevolence (仁), righteousness (义), courtesy(礼), wisdom and trust can be found in the lead character Zhou Bingkun, the youngest son in the family.  In the show, Zhou Bingkun used to be a factory worker, the one who has taken care of the big family and friends selflessly.

Following the lives of Zhou's family, the drama gives viewers an insight into the lives of ordinary Chinese. It is the kind of show that strikes your heartstrings and leaves you in tears even if you've already read the book.

A. No wonder viewers thought highly of this drama.

B. It is time to create such a drama to remember the bygone times.

C. China has witnessed dramatic changes over the past five decades.

D. And it explores themes of family, friendship and romance in a bittersweet story.

E. He was played by Lei Jiayin, who says he can almost "see his father" in the drama.

F. Disney has also announced it has acquired the drama series for an international release.

G. Most of the narrative took place in a shantytown (棚户区), where Zhou's family lives.

Bacteria are a troublesome problem for astronauts. The microorganisms(微生物)from our bodies grow uncontrollably on surfaces(表面)of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA solving this very tiny big problem? It's turning to a group of high school kids. But not just any kids. It's depending on NASA HUNCH high school class, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.

HUNCH is designed to connect high school classrooms with NASA engineers. For the past two years Gordon's students have been studying ways to kill bacteria in zero gravity, and they think they`re close to a solution. "We don't give the students any breaks. They have to do it just like NASA engineers," says Florence Gold, a project manager. "There are no tests," Gordon says.

"There is no graded homework. There almost are no grades, other than ‘Are you working towards your goal?' Basically, it's ‘I've got to produce this product and then, at the end of year, present it to NASA.' Engineers come and really do an in-person review, and… it's not a very nice thing at time. It's a hard business review of your product."

Gordon says the HUNCH program has an influence on college admissions(录取)and practical life skills. "These kids are so absorbed in their studies that I just sit back. I don't teach." And that troublesome bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.

Queen Elizabeth National Park is a place of outstanding beauty and extreme biodiversity. On a previous underwater assignment with my wife and photographic partner, Jennifer Hayes, we'd documented healthy coral reefs surrounded with fish, sharks, and crocodiles. We knew that time, increased tourism and climate change could make the park different—so 15 years later, we returned to see how it was going.

We were photographing some jellyfish. Jennifer, her back to me, was focused on something above her. Out of the corner of my viewfinder, I saw a sizable crocodile coming. As I began to take its photograph, I realized that the crocodile was going to swim directly between Jennifer and me. I started to make loud noises through my regulator and moved towards Jen, firing a burst of flash-lit shots to warn her that we had company. She quickly detected my signal and turned to meet our visitor. 

She gave me a quick thumbs-up, nodded OK, and said "Hello, handsome" as she bent closer to take its photos. I admired her for treating the crocodile with respect, calm curiosity, and absolute joy. She didn't feel threatened. She was familiar with this kind of crocodile in this particular place—and she had a big underwater camera housing that could double as a mighty shield (盾牌) if needed. After a few pictures the crocodile, unimpressed with us, swam downstream on its way to do other crocodile things. We continued our search for jellyfish.

There is always risk in our line of work. But this encounter highlighted the good news that we saw all around us here. The crocodile is an indicator animal, a symbol of a healthy ecosystem that can support top predators (捕食性动物). The easing of travel restrictions is bound to bring more tourists—so it's vital to maintain a balance among ecotourism, exploration, and conservation. That's possible if visitors adopt the same philosophy that we hold toward that curious crocodile. We enter Earth's oceans on their terms, not our own.

"Mom, where do you suppose they are?" my ten-year-old son Danny asked for the twentieth time as he stared out of the window at the range (牧场). "They" were our horses, Ginger, and her three-year-old son, Charcoal, both of whom had been missing for days.

Our range and woods offered plenty of grass for six horses. However, spring thunderstorms during the past ten days had forced the nearby river out of its banks. The other horses had come to the barn (畜棚) during the downpour, but not Ginger or Charcoal. 

When the rain stopped, I took Spot, our dog, to do some first-hand searching. We went through trees and brush in wet lowlands near the river. All my calling and Spot's smelling were in vain.

The next morning, the sun struggled to shine through gray clouds, but dampness filled the air. Suddenly, Danny shouted, "Mom, come quick! There's Ginger!" The horse stood at the range gate crying impatiently and moving back and forth as if to say "Follow me".

"Hurry, Danny," I said, "get the pot with some oats (燕麦). I will bring a rope. " Ginger walked in front and we followed. "I see him! I see him!" Danny shouted. Charcoal was lying on his side, not moving. His right back leg was badly injured.

"Oh, Mom. How long do you think he's been lying here with no food and nobody to care for him?" Tears formed in Danny's blue eyes. "Probably several days, but we'll never know. Ginger took care of him, though, protecting him from attacks from hungry wolves or other wild animals," I said.

"What can we do now?" Danny asked anxiously. "There's no way to drive a vehicle down here in all this mud. " "We just have to get him up and lead him out," I said, keeping my voice confident. "Afterwards, we'll have to call the vet (兽医) out. "

To celebrate the 50th anniversary of the World Heritage Convention (《世界遗产公约》), Beijing held event titled "The Next 50 Years: World Heritage Where Challenges and Development Coexist", during which experts discussed how (make) the sites more accessible and sustainable for future generations.

Since joining the World Heritage Convention in 1985, the number of world heritage sites in China  (grow) to 56, including the Great Wall, the Forbidden City and the Grand Canal,

 (allow) the nation to rank second in the world. And over the past decade, China has added 15 new world heritage sites, six of  have been included in the relevant lists of intangible cultural heritage (非物质文化遗产). 

Chinese experts said that the 56 listed world heritage sites reflect the country's

(abundance) heritage and that China's cultural heritage achievements over the past 10 years can be seen in many aspects.

For example, in 2013, the Tianshan Mountains  (list) on the World Heritage List. The beauty of Tianshan lies  its snow-capped mountains and glacier-capped peaks. It is really an outstanding example of a mountain ecosystem with a  (diverse) of landform features and ecosystems. 

Experts said that the world heritage application is just a means to perform better protection. We should behave more  (responsible) to conserve the heritage of all humanity. 

When I was a child, my family went to the beach often. However, we 1  played in the sand or swam in the ocean. Nature was to be 2  far away, with the car windscreen in between. We would wave to the sea from our 3 , watch the sunset and drive home. My parents were 4  in crowded and polluted cities. Their upbringing made them think maybe it was 5  for kids to stay inside. Without knowing it, I was 6  by their attitudes. 

It was my own children who led me to another 7 . They liked observing earthworms and jumping in mud; their such 8  about the natural world allowed me to see it in a 9  way. On beach trips, I found myself 10  to dig into the sand with them and 11  its cool graininess (颗粒感) as they buried me in it. 

Last summer, my love for 12 led to us buying a house in a farming town near a mountain. It's something I wouldn't have 13 as a city girl. I've found a deeper connection to nature and I'm grateful for it. There are miles of tracks around us that I 14 every day. I walk through snow, mud and rain, 15 my boots — which I bring straight into the house.

Patience is something that many of us struggle with. I know that I am certainly one who has a hard time dealing with delays. After all, we live in a world of instant satisfaction and overnight shipping. We can have anything that we want delivered to our doorstep right away. We can pick from a variety of entertainment options at any given moment. 

The truth of the matter is, however, that anything good rarely happens quickly.  You have to develop your patience over time by taking real action. This applies to a number of things: launching a business, waiting to go to an event, or striving to achieve your personal goals. 

Here are a few tips to help you become more patient:

Make yourself wait on things. This can include eating, purchasing items, or taking any sort of action.  It will help you increase your current patience levels and become less anxious moving forward. Try it. 

Sometimes pause actually means there is hope. Perhaps you'll meet a lot of wonderful people while waiting in line, or you will find that something put off is actually better in the future.

Understand that life is full of delays.  If there were delays, we would all have to accept. Ups and downs are what build character, and often, the longer we wait, the more we enjoy it. So wait it out with the best of them. 

A. It usually takes a lot of work and a long wait. 

B. The more patient you are, the luckier you become. 

C. Teach yourself to look on the bright side of delays. 

D. There is no one straight path to happiness or success. 

E. Being patient is a must if you want to achieve success. 

F. As a result, being patient has become increasingly difficult for most of us. 

G. Work to overcome whatever makes you anxious and force yourself to wait. 

Parks are the beating hearts of cities, providing crucial environments for wildlife of many sizes as well as areas of rest and recreation for local citizens. Accessible via public transport, and located near a university, a stadium and the National Library, Warsaw's Pole Mokotowskie Park provides green space for many people.

One of the International Union for Conservation of Nature's five pathways to transformative change for water management is to restore species population, ecosystems and the benefits that nature provides to people by using each city's advantage. As more urban centres seek new ways to unite greenery into the built environment, projects of all sizes and stages add to essential corridors and stopping points for a range of wildlife.

Tasked with improving Warsaw's Pole Mokotowskie Park's natural sustainability, architecture company WXCA looked at ways of enhancing the elements that were already in place to better support wildlife. One of the most visible means was the removal of thousands of square metres of concrete (混凝土). Removing concrete in and around ponds and other waterways allows the city's features to shape themselves naturally, in reaction to both the surrounding environment and the weather. Doing so can support biodiversity by removing artificial constraints and flows. More than 13,000 square metres of concrete has already been removed, with more removal planned over the next year.

For the human users of the park, the designers created education, activity, and art spaces. The Grand Salon, a grassland surrounded by trees, is for large public gatherings, and a handful of pavilions (亭) spread throughout the space provide visible means of monitoring the quality of the air and water. They also contribute to the park's ecosystem through rainwater harvesting. As the temperature consistently rises, city planners are using the leaves and branches of the plants and mixed use designs to reduce heat islands, improve air quality and prevent urban runoff.

Turning on the air conditioning can bring sweet relief from the heat. But your resulting energy bill? Not so much. What if your home could stay cool all on its own? That's the premise (前提) of Zheng Yi's new invention. The associate professor at Northeastern University in Boston has created a sustainable material that can be used to make buildings or other objects able to keep cool without relying on conventional cooling systems.

Zheng imagines this material covering the roofs of houses or other buildings. The material, which Zheng has named "cooling paper", has light colors and internal microstructure with many small holes. It reflects those warm solar rays away from the building, and it also absorbs heat inside — heat that is from electronics, cooking and human bodies.

Cooling paper is, in fact, made of paper. One day, Zheng saw a container full of used printing paper. He thought to himself, "How could we simply transform that waste material into some functional energy material?" So, with the help of a high-speed blender (搅拌机) from his kitchen, Zheng made a pulp (浆状物) out of it and the material that makes up Teflon, a type of plastic. He then made it into waterproof "cooling paper" that could coat homes. Then, he and his team tested its ability to keep cool: it can reduce temperatures by as much as 6 ℃. He selected materials that would reduce the cost of using the new technology to cool homes.

The cooling paper isn't just green in its ability to reduce your energy footprint. The material can be used, exposed to solar radiation and various temperatures, and then reduced to a pulp (again) and remade without losing any of its cooling properties. "That is incredible!" Zheng says. "We thought there would be maybe 10 to 20 percent of loss, but no. It's just as well as the original. "

For over a decade, Zubin Kanga, a pianist, composer and technologist, has changed the limits of the forms of musical performances. He has both organized and performed shows that have pushed barriers, with motion sensors, artificial intelligence (AI), live-generated 3D visuals and virtual reality among the technological advancements used to unlock new possibilities of music and performances. 

Kanga's approach to employing cutting-edge technology was first informed by the relative limitations of his chosen instrument. "The piano is a very accurate technology," he says. "From the early 20th century till now it hasn't really changed at all. It's an amazing instrument, but it does have certain limitations in terms of the types of sound you can create. "

One of the early works is Steel on Bone, composed by Kanga himself. He performs the piece using MiMU multi-sensor gloves. "I can put up one finger, and that'll produce a particular sound," Kanga explains. "And then I can control that sound just by moving my wrist through the air — I can do that with lots of different gestures. "

"For Steel on Bone, I'm actually playing inside the piano with these steel knitting (编织) needles, and getting all these interesting effects on the strings. Then I'm using samples of them. Sometimes I'm using live delays and operating them. The sound can change depending on how my hands are moving. It allows me to make a very theatrical piece, and people can see this immediate connection between how I'm moving — these very big, almost conductor-like gestures through the air — and the way the sound is changing," said Kanga.

This is just the start, and Kanga goes on to be enthused with the use of motion sensors to make music, the possibilities that AI offers composers as a tool, and how virtual reality could transform performances and more. 

Books are excellent gifts. Here are four of the year's most talked-about titles.

Ordinary Monsters | By J. M. Miro

Miro has temporarily abandoned literary fiction in favour of a new series of historical fantasy novels. Ordinary Monsters is about a group of children with magical gifts who come together and pool their powers to escape the bad shape-shifting man that's going after them.

Son of Elsewhere: A Memoir in Pieces | By Elamin Abdelmahmoud

The soundtrack to The O. C. , a drama series, and the strange beauty of Highway 401 were important factors in developing selfhood of Abdelmahmoud. This book describes his own experience of moving from Khartoum, Sudan, to Kingston, Canada, in the early 2000s at age 12. 

A Magic Steeped in Poison | By Judy I. Lin

Harry Potter has his magic stick. And Ning, the heroine of Lin's first novel, has tea, which in her world carries magical properties. Lin has created a pleasing Young Adult fantasy rich in Chinese mythology (神话). In this book, Ning enters a competition to find the most gifted tea master, Shennong.

A Ballet of Lepers | By Leonard Cohen

Unlike many other posthumous (死后出版的) works, you can count on Cohen's to be worth your wait. Before his death, he said that the novel contained in the book, which was never published, was likely better than The Favourite Game, a novel he published during his lifetime. This book also includes a radio play script (剧本) and a handful of short stories.
