Aunt Karen always had a special place in my heart. When I was growing up, I knew I could count on her to have room for me on her lap and words of love and encouragement when I needed to hear them. When she died five years ago, I was devastated. The whole family was still in shock when her husband, Uncle Ronnie, died a week later. I longed to have a small item of Aunt Karen's to remember her by, but seeing her children and grandchildren overcome by the grief of this double loss made me shy away from asking.

    A few months after Aunt Karen's death, I was on my way to work when I saw Rescued Treasures, a local second-hand store. I only had a couple of dollars on me and didn't really intend to buy anything, but I stopped anyway just to look inside. I had been shopping around for a few minutes when a small, black handbag caught my eye. It wasn't fancy or special. I didn't really need a handbag and continued to look around the store, but something kept drawing me back to that handbag. Finally, I checked the price tag (标签). It was just one dollar.

    The handbag stayed in the back of my car for weeks until I came upon it during a car clean-up. I opened it up. I couldn't believe it. They hadn't even cleaned it out. It was still full of junk, old candy wrappers, old receipts (收据) and used paper. Usually the store emptied things inside, so there wouldn't be any surprises for a new owner.

    I threw away some wastes, and sorted through the receipts, when I found one item in the small inside pocket. It was an insurance card with the name “Karen Stair” written on it. I began to cry. My beloved Aunt Karen. This was her handbag.

    Four years ago, Chris Nagele did what many other technology CEO have done before—he moved his team into an open concept office.

    His staff had been working from home, but he wanted everyone to be together. It quickly became clear, though, that Nagele had made a huge mistake. Everyone was distracted, productivity(生产率) suffered and the nine employees were unhappy, not to mention Nagele himself.

    In April 2015, about three years after moving into the open office, Nagele moved the company into a 10,000-square-foot office where everyone now has their own space — complete with closing doors.

    Numerous companies have accepted the open office. But we're 15% less productive, we have great trouble concentrating.

    Since moving, Nagele himself has heard from others in technology who say they long for the closed office lifestyle. It's unlikely that the open office concept will go away anytime soon, but some companies are following Nagele's example and making a return to private spaces.

    There's one big reason we'd all love a space with four walls and a door that shuts: focus. The truth is, we can't multitask(多任务化) and small distractions can cause us to lose focus for upwards of 20 minutes.

    What's more, certain open spaces can negatively impact our memory. We retain(保留) more information when we sit in one spot, says Sally Augustin, an environmental and design psychologist in La Grange Park, Illinois. It's not so obvious to us each day, but we offload(卸下) memories — often little details — into our surroundings, she says.

    Beside the cheaper cost, one main argument for the open workspace is that it increases teamwork. However, it's well documented(记载) that we rarely brainstorm brilliant ideas when we're just talk casually in a crowd.

A hybrid electric vehicle (混合动力车) or HEV is a vehicle driven by the combination of petrol engine and electric motor. Terrence has been driving a HEV for five years. He really doesn't understand why more people aren't accepting them. "I probably spend about $ 7 a day on petrol," the taxi driver told news. com. au. In his previous conventional vehicle Terrence said he was spending up to $ 30 a day on petrol, meaning he saves almost $ 6000 every year.

The Toyota spokesman said this was quite a high saving and official tests estimate (估计) an average driver would only save about 33 percent off their current bill. This means a driver paying $ 30 a day on petrol would see their bill drop to about $ 20 using the hybrid. "A taxi driver that drives in built-up areas and spends little time on highways will notice a higher fuel saving," he said. "Low speeds allow the electric motors to be used more and the petrol engine used less."

While some people are skeptical about how reliable hybrids are, Terrence said he had never run out of power. His Camry cost about $ 34,000 and so after five years, it's nearly paid for itself. "For cab drivers, it's a real advantage because of the cost-effectiveness," he said. Terrence has no complaints about the car. "I love it, the calm and quietness of it, the simplicity of it—you just jump in and go. The maintenance（保养）is really low. But the only difficulty is finding someone to service the car as there are not many experienced mechanics（机修工）."

Terrence said it's "extraordinary" that more drivers aren't buying more hybrid electric vehicles and that governments are not encouraging this more. "I think people have a view that you have to plug it in, which is not true. A lack of information about the cars may be stopping people from taking the plunge. It's not promoted at all for the public to understand—it's simplifying the actual owning of a car—you don't have to do so many things to own it and run it, it's just so much simpler. Why wouldn't the government promote such a thing?"

    Internet slang refers to a variety of slang languages used by different people on the Internet. It is difficult to provide a standardized definition of Internet slang due to the constant changes made to its nature. However, it can be understood to be a type of slang that Internet users have popularized, and in many cases, have coined. Such terms often begin with the purpose of saving keystrokes or to compensate(补偿)for small character limits. Internet slang consists of a number of different ways of speaking, sub-languages, expressions, spelling techniques and idioms that have obtained most of their meaning on the Internet.

    Love it or hate it, there is no escape from Internet slang. It has become popular among the teenagers. Just like US teenagers use “LOL”(laugh out loud) when commenting on a funny video, China's post-00s generation, a group born between 2000 and 2009, like to use “XSWL” (laughing my head off). Acronyms(首字母缩略词) and shortened expressions may be popular as they offer shorter ways of communicating. For teenagers, they could also allow them to communicate in their own way.

    Understanding the most common acronyms and texting symbols can help to decode and decipher any text message, email or instant message online. Here are some of the most popular symbols, abbreviations, and acronyms you are likely to stumble upon when texting or receiving messages and chatting on line. OMG: Oh my God; BRT: Be right there; TTYL: Talk to you later; JK: Just kidding; G2G: Got to go; NMU: Not much, you? RBAY: Right back at you; IDC: I don't care.

    Some people think that Internet slang affects the language negatively. However, Melbourne University linguist Rosey Billington doesn't agree.

    “When you are able to use language in a creative way, you show you are linguistically knowledgeable because you know the language rules well enough to use words in a different way.”Billington told News.com. Au .Her view is supported by two linguists, Lauren Spradlin and Taylor Jones.

    The Franklin Institute is one of the oldest and most beloved science museums in the United States.

    Why visit

    In 1824, the Franklin Institute opened in Independence Hall in memory of Benjamin Franklin and his scientific achievements. In 1934, with the construction of the current building and the nearby Eels Planetarium, it became a hands-on science museum.

    Today, it holds the distinction (荣誉) of being Pennsylvania's most visited museum. In the museum's rotunda (圆形厅), a 20 foot-tall marhle statue pays respect to the Founding Father and famous scientist.

    Must-See

    While the entire museum offers interactive (交互式的) fun, highlights include the high-tech Your Brain exhibits (展品), which offers a glimpse into the inner workings of the human brain; Sports Zone, which focuses on the scientific aspects of sports; Two Escape Rooms, where participants solve puzzles and riddles before lime runs out; and the on site Virtual Reality Demonstration Space.

Smoking is harmful.But as soon as you quit the habit, everything will be OK,right?Wrong.

New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time.In the research, a team of US scientists studied the blood of 16,000 people.Among them, some were smokers, some used to smoke, and the rest were non-smokers.Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes.Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.They can stay for as long as 30 years.It's almost like leaving a footprint on wet cement (水泥)—it will always be there,even when you've walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side:the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.
