Questioning the existence of aliens is something that scientists have done for decades. In fact, most people do believe that aliens exist in some fashion. The main necessities for life are water and some form of energy source. Not surprisingly, there are some planets, exoplanets and moons that fit the bill. Here are several best chances at finding life in the universe.
TRAPPIST-1 is a planetary system a few dozen light-years away, whose discovery was announced in early 2017. This system consists of seven Earth-like exoplanets orbiting an "ultra-cool" star, and it is one of our shots at finding possible life beyond our own solar system.
Titan is the largest moon of Saturn, the sixth planet from our Sun. This moon could potentially harbor life but possibly not in the sense that we think. Titan does not exactly fit the description of being in a typical habitable zone.
Titan has water, and it has liquid. It just doesn't have liquid water. The water on this moon is completely solid because of the extremely cold temperature.
Europa is one of Jupiter's moons here in our own solar system. It is another candidate due to its potential to hold liquid water. Europa is thought to have all the necessities for life including water, energy sources, and the right chemical build-up.
The Red Planet, the fourth from the Sun, is probably one of the most talked-about potential candidates for extraterrestrial(地球外的) life and even for human colonization. Despite some different voices, finding extraterrestrial life on Mars really is a serious possibility.
We know by now that we won't find little green men or any intelligent form of life that we understand. However, there is evidence that there was and may still be microscopic life on the small red planet.
The common point of these celestial bodies is that _______.
Which celestial body could have life different from human imagination?
Which of the following statements is TRUE?
About a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”
My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”
Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.
The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”
As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.
Why did Lori make the call?

Careers in zoology are extremely varied and unique, and can provide incredible learning and work opportunities for anyone devoted to animal studies and welfare. Zoology, or the study of animals, is a wide field with many specialties, including research, conservation, veterinary (兽医的) medicine, and the care of animals. For people with a love of animals and some training, dreams of careers in zoology may come true.
Some careers in zoology focus on research and scientific studies. These careers may allow those with a good theoretical science background to develop and run studies that improve human understanding of the animal world. Research in zoology can help create safer and more effective products for animals or can teach humans more about animal behavior in order to aid in conservation, breeding programs, and habitat preservation.
Careers in zoology that focus on conservation attach great importance to the continued survival and increased protection of animal species. Conservationists may work with political groups or governments to help make laws to protect and preserve animals, or may work in the field gathering information on potential threats to the health of global ecosystems. Some conservationists work in educational fields, trying to improve human efforts to save animals from extinction.
Animals are subject to illness and injury, and some careers in zoology help to create a safe, stable animal population. Veterinary medicine is an important specialty field, and may take several years of intensive training to qualify as a certified veterinarian. While many veterinarians focus on the small-animal practice of domestic pets, vets in rural areas often work with large farm animals and more adventurous veterinarians may work with exotic species in zoos and wildlife preserves. .
Humans love to observe animals, and modern-day zoos and wildlife preserves help meet that interest while providing facilities to assist with conservation programs. Zoology careers in zoos can range from overseeing breeding programs, to creating the proper diet for a deer, to cleaning the tiger’s cage. Many volunteer and entry-level jobs are available for people that love animals.
What is the purpose of researching on animals in zoology?
What can careers in zoology that focus on veterinary medicine help?

NEW YORK－A massive winter storm paralyzed much of the US East Coast on Thursday and Friday, dumping as much as 46 centimeters of snow from the Carolinas to Maine. It also caused flooding on the streets of Boston due to swelling storm tides, forced the cancellation of nearly 5,000 flights and closed businesses, offices and schools.
Some meteorologists (气象学家) classified the storm as a "bomb cyclone" for its sharp drop in atmospheric pressure would be followed immediately by a blast of cold air that could break records in more than two dozen cities and bring wind chills as low as -40℃ during the weekend.
From Baltimore, Maryland, to Caribou in Maine, efforts were underway to clear roadways of ice and snow as wind chill temperatures were to plunge during the day, reaching -40℃ in some parts after sundown, according to the National Weather Service.
Utility companies across the East worked to repair downed power lines early on Friday as about 21,000 customers remained without electricity, down from almost 80,000 the day before, and issued warnings that temperatures may become dangerously low.
"If the temperature in your home begins to fall, we recommend taking shelter elsewhere until service can be restored. You can find warming centers by contacting local authorities," National Grid power company, which serves Massachusetts, said on Twitter.
Airlines canceled 4,000 flights on Thursday and hundreds more on Friday, according to FlightAware.com, an online tracking service.
Mayor Bill de Blasio said it could feel like -30℃ on Friday and Saturday nights with the wind chill. "This is a serious, serious storm, and may be the most severe in 2018," he said at a news conference.

"A question brought me to the point of ending my life when I was fifty years old. My question was the simplest one that lies in every person. It is the question without which life is impossible: Why do I live? 16 Is there anything in my life that will not be destroyed by my death?"
These are the words of the famous Russian writer Leo Tolstoy. Many people ask these difficult questions. And they struggle to find meaning in their life. Tolstoy spent his whole life trying to answer difficult questions like these. 17
In the 1850s, Leo Tolstoy wrote his first stories. He wrote about his experiences in the military. He also told stories about when he was a child. 18 He was finally successful. He earned respect from many wealthy and intelligent men, who talked a lot about faith and the meaning of life. But soon he found they were proud and they made very bad moral choices.
19 He opened a school for the children of people who worked on his land. They were very poor. He wanted to help them because he thought they were more honest than the wealthy people he knew.
Tolstoy learned many things from his workers. He respected how they worked hard to provide for their families. 20 So in 1862, Leo Tolstoy married a young woman named Sonya Behrs. The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books-- War and Peace and Anna Karenina. They communicate what he thought was the answer to all his questions-- humans were supposed to live a simple life and take care of their families.
A. These works were published and Tolstoy became a well-known writer.
B. How can I realize my dream if I have one?
C. Why do I wish for anything, or do anything?
D. He gained a lot of inspirations which had great influence on his following actions.
E. His search for answers influenced his writing.
F. So in the 1860s, Tolstoy tried a different way to find the meaning of life.
G. He began to believe that marriage and family would give his life meaning.
I come from one of those families where you have to yell at the dinner table to get in a word. Everyone has a strong 21 , and talks at the same time, and no one has a 22 leading to heated arguments. We often talk or even debate with each other on different topics.
23 a family like mine has made me more 24 about the world around me, making me tend to question anything anyone tells me. But it has also made me realize that I’m not a good listener. And when I say “listening”, I’m not 25 to the nodding-your-head-and- 26 -answering-Uh-huh-or-Ooh-I-see variety. I mean the kind of listening where you find yourself deeply 27 with the person you’re speaking with, when his story becomes so 28 that your world becomes less about you and more about him. No, I was never very good at that.
I spent summer in South Africa two years ago. I worked for a good non-profit 29 called Noah, which works 30 on behalf of children affected by AIDS. But 31 you asked me what I really did in South Africa, I’d tell you one thing: I listened, and I listened. Sometimes I 32 , but mostly I listened.
And had I not spent two months 33 , I might have missed the 34 moment when a quiet little girl at one of Noah’s community centers, orphaned (孤儿) at the age of three, whispered after a long 35 , “I love you.”
36 that summer, I knew how to hear. I could sit down with anyone and hear their 37 and nod and respond at the 38 time—but most of the time I was 39 about the next words out of my own mouth. Ever since my summer in South Africa, I have noticed that it’s in those moments when my mouth is closed and my 40 is wide open that I’ve learned the most about other people, and
perhaps about myself.

A lot of films have tried to describe the afterlife and our memories of family members, 41 few have done as well as Coco, Disney Pixar’s 42 (late) masterpiece animation, which hit the big screen on Nov. 24, 2017.
43 (inspire) by the Mexican holiday of Dia de los Muertos — Day of the Dead — the film’s production team created a young boy, Miguel, who wants his family to understand his love of music. 44 that year’s Dia de los Muertos, 45 accident takes him to the Land of the Dead. In this land, there are friendly skeletons who can cross a bridge made of flower petals to visit their living family — that is, as long as their family still puts their photos on the family shrine (神龛). Those spirits who 46 (forget) by their family will disappear completely. So it’s in this magical world 47 Miguel gets to meet and discover the truth about his great-great-grandpa.
In an era 48 young people are so 49 (easy) attracted by celebrities, Coco reveals the emptiness of such flattery, teaching kids to preserve and respect the memory of their elders while 50 (remind) them that the source of true creativity is so often personal.
Smartphone apps certainly make our life easier. And now, it looks like they could even do our homework for us. Recent years have seen the release of a various of study aid apps aimed at student. Most of these apps allow users to take a photo of our schoolwork and the correct answers will just appear on their smartphones. Convenient they are, these apps present problems with both parents and teachers. Most students just copy the answers from the app, while only a few use the app to study. Better still, some students even use the study aid apps as social networks. Therefore, this isn’t to say that study aid apps should be completely ban. Parents and teachers should give necessary guidance to help students to take the advantage of the study aid apps’ strengths and avoiding their weaknesses.
