Later someone comes to ask you if you have __________some money he lost. What will you do?
She then ordered us to write down the __________ , and asked us to take our whole lives to try to find out our own __________to it.
I don’t know about the other eleven __________ . Speaking for myself I can say: it was the most __________single thing of my life. __________ , I have been asking this question to myself when I have to make a __________ .

Endangered Species Day is a bittersweet event. While it's heartbreaking to think back on all the species we have already lost during our last few generations, and all we stand to lose in the next few.1..
Make a donation to a conservation organization. Every penny helps these local, national and interactional groups to do on-the-ground work in protecting habitats and species.2..
Visit your local natural history museum virtually. You'll learn a lot about your local wildlife including species that may be threatened with decline. Endangered species aren't just rhinos in Africa or leopards in Asia- they're also the insects, birds, mammals and even plants right in our own backyards, and many times there is the opportunity to protect them.
Join a wildlife conservation organization. There are many organizations to choose from including the National Wildlife Federation, National Audubon Society, Wildlife Conservation Network and more.3.. Your membership shows your ongoing support and also provides a way to stay in the loop about what's happening and how you can help.
4.. Today is the perfect day to send a few tweets, add a few Facebook updates, photos about endangered species conservation. You can be a source of information and awareness today and perhaps inspire even more people to get involved!
Stay informed! Make it a daily practice to check in on news about endangered species on a local, national or global level. You'll be able to see when and how you can help.
Many species are endangered now, but we can change that; we can end poaching, habitat destruction, pollution and so many other factors causing declines around the world,5..
A.Even if it's just $5, it helps
B.It is time to get involved and make a difference
C.So let's celebrate it with as many people as possible
D.It's also a chance to look at some ways we can get started
E.Volunteer to work in some wildlife conservation organizations
F.Take to social media with information about endangered species
G.You can join a larger organization or even one that focuses on specific species or habitats
Fever, coughing, sore throat… most of us at one time or another have had these symptoms. What causes them? In fact, many diseases are caused by viruses, including some deadly ones like AIDS, SARS and COVID-19, also known as the novel coronavirus pneumonia, outbreak in China.
What are viruses? How can viruses cause so much trouble? Viruses are very small particles (颗粒) which are about one millionth of an inch long. Unlike human cells or bacteria, viruses aren’t living organisms- they can't reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.
Virus can infect every living thing- from plants and animal down to the smallest bacteria. For this reason, they are always a potential danger to humans. Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.
But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. "Tracing the origins of viruses is difficult, "Ed Rybicki, a scientist at the university of Cape Town in South Africa, told Scientific American, "because viruses don' t leave fossils and because of the tricks they use to make copies of themselves within the cells they've invaded.”
However, there are three main theories to explain the origin of viruses. First, viruses started as dependent organisms, then became parasites(寄生者)。Second, viruses evolved from pieces of DNA or RNA that "escaped" .from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.
For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most reasonable explanation. Continuing studies may provide us with clearer answers or future studies may find that the answer is even more mysterious than it now appears.

“What kind of rubbish are you?” This question might normally cause anger, but in Shanghai it has brought about complains over the past week. On July 1st, the city introduced strict trash-sorting regulations(垃圾分类制度) that are expected to be used as a model for our country. Residents must divide their waste into four separate categories and throw it into specific public bins at scheduled times.
Violators(违规者) face the possibility of fines and worse. They could be hit with fines of up to 200 yuan($29)。 For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain bank loans or even buy train tickets.
Shanghai authorities are responding to an obvious environmental problem. It generates 9 million tons of garbage a year, more than London's annual output and rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to examine carefully through the waste, plucking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up.
Many residents appear to support the idea of recycling in general but are frustrated by the details Rubbish must be divided according to whether it is food, recyclable, dry or hazardous, which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and throw it by hand. Most annoying are the short windows for dumping trash, typically a couple of hours, morning and evening. Along with the monitors(监控) at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out. After all, no one wants to look bad.

Addyson Moffitt is an 8-year-old from Kansas City, Missouri, Maurine Chelagat is a 9-year-old from a village in Kenya called Bartabwa. It might not seem as if the girls have much in common, but when they met at a dinner two years ago, in Kansas City, they instantly hit it off. ''We had this one little red ball to play with,'' Addyson told others. ''We didn't have any electronics or phones, no iPads or TV. It was just us playing.''
The dinner was hosted by the nonprofit group World Vision International. In some parts of the world people must walk several miles each day to collect water from a stream or another water source. Often, the water is polluted, World Vision builds wells, pipelines, and rain catchers in these communities. Addyson was at the dinner because her family supports World Vision. Maurine was there because her village been without clean water. World Vision fixed that by building a water station there. Addyson was inspired by Maurine. "People helped Maurine so she could have clean water, and kids are dying because they don't have. Races are one way World Vision raises money to pay for its water projects. Runners pledge to run a have it, "she says. ''I want to help.''
Races are one way World Vision raises money to pay for its water projects. Runners pledge to run a race, often a 26-mile marathon or 13-mile half marathon. They ask people to support them by donating to World Vision. Addyson decided to run the 2017 Kansas City Half Marathon for World Vision. At age 7, she was one of the youngest-ever runners in the race, and had to get special permission to participate.
Addyson spent four months training with her parents, waking up before 6 a.m. to run. Meanwhile, she started fundraising. She carried a jug of water around her neighborhood, to park conversation about World Vision's work, She bused tables at a restaurant for tips. She asked friends to make donations as birthday presents. By October 2017, when Addyson ran the race, she'd raised more than $20,000. She's the youngest person in World Vision history to raise more than $10,000. In 2018, she ran again-and raised $36, 000. But Addyson's work is not finished. "My goal is for every kid to have clean water," she says.

If you’re single this Valentine's Day, don't settle for another night of being alone. Single ladies and dudes can celebrate, too. Below, five holidays from around the world to celebrate instead of Valentine's Day this year.
Singles Awareness Day
In the U.S., we have “Singles Awareness Day”--a humorous anti-Valentine's Day celebrated on February 14 or 15, depending on your preference. On these days, singles toast their uncoupled status.
Ystävänpäivä or Friendship Day
Finland has a more ideal take on Valentine's Day: February 14 is considered Ystävänpäivä or “Friendship Day”, which is marketed as a celebration of friends. (We'd recommend adopting this holiday if you're looking for an occasion to hang out with your best friends.)
Black Day
April 14 in Korea is known as Black Day, a holiday where singles gather in local restaurants and drown their sorrows in cheap, but delicious bowls of jajangmyeon--- a Chinese-Korean noodle dish swimming in chunky black bean sauce, and topped with pork and veggies. The holiday has been popular over the last decade, and we can't say we're surprised. It's hard to be sad about being single when you're dipping into a bowl of something that delicious.
Single's Day
November II marks Singles' Day in China, an unofficial holiday that started in the 1990s as a protest Valentine's Day and that's now a day where singles buy stuff--a lot of stuff- for themselves. In 2013, China's biggest online shopping company took in more than $5.75 billion in online payments on Single's Day-two and a half times the total American retailers（零售商） netted on Cyber Monday the same year.
International Quirkyalone Day
Another option for singles looking to get in on the celebratory action on February 14? International Quirkyalone Day, a “do-it-yourself celebration of romance, friendship, and independent spirit," according to the official site. The founder of the event swears her holiday is not an anti- Valentine's Day; instead, it's a celebration of all kinds of love: romantic, platonic, familial, and yes, self-love. "In other words, it's a day to do whatever you want, with whoever you want. We can get behind that and have a great time.
