We have heard about people who have special memories. Recently there has been a report about a woman from Australia who can remember almost every detail（细节）of all the events in her daily life.

Rebecca Sharrock, 25, is one of just 80 people worldwide who have been identified（确定）as having Highly Superior Autobiographical Memory（HSAM, 超级自传体记忆症）. It means she can remember every small event which most people would forget with in（在……以内）days as if it had happened just minutes ago.

“I remember my mum putting me in the driver’s seat of a car and taking a picture of me when I was 12 days old,” she said. “That’s my earliest memory. I remember every day since then. I can’t tell all the dates exactly because I was too young to understand calendars, but I remember what I did that every day, what the weather was like and so on.”

Rebecca can also re-experience taste. If she’s eating something that she doesn’t like, she thinks about Black Forest cake, her favorite food, and the memory will be so strong that she can nearly “taste” it.

However, sometimes her memories prove to be painful. Because they’re not just events that she remembers. “When I relive（再体验）memories, the feelings return, too,” Rebecca said. “For example, I remember falling over when I was three at my grandparents' house and hurting my left knee. Talking about it now, I feel painful in my left knee.”

“At night, I have to sleep with the radio recorder and a soft light on, she added.” If it’s too dark or quiet, my mind would be filled with all these memories and I can’t sleep.

Searching for parking spaces has long been a headache for many office workers in big cities across China, especially for those working in central business districts. Parking near their companies for five days a week could cost them a lot of money. At the same time, with prices for parking lots(停车场) in residential areas(居民区) rising, most of their spaces remain unoccupied(闲置的) during workdays.

Now a new form of sharing economy has appeared in China — the shared parking space. It has become a huge market in some Chinese big cities.

In Qingdao, up to 10,000 personal parking spaces have been turned into shared ones with the help of Airparking, an online shared parking platform(平台) developed by a network company from Guangzhou.

Through a special app, users can either share or order a parking place. Owners who have idle(空闲的) parking spaces can share some information, including the parking position, license number and time limit(限制) in the platform. With the information, users can easily find the nearest place to park. The average(平均) parking cost for shared parking is four yuan each hour, almost the same as the service fee(费) in traditional parking spaces.

Qingdao is one of the Chinese cities that encourage shared parking. Some other big cities, including Beijing, Shanghai and Hefei, have also begun to try this idea. The Shanghai government, for example, has set up more than 6,500 shared parking spaces to encourage the public to use. Shared parking will be more and more helpful to drivers.

On January 23, the Winter Olympic Villages opened to prepare for the coming games. Lots of cool technologies (技术) have attracted the attention of many people. Among them, the smart beds are one of the most exciting examples.

The smart beds in the Winter Olympic Villages are made of memory foam (海绵橡胶) and have their own alarm clocks. After setting the time, the smart beds will go up and down by themselves when the time comes to remind (提醒) players to get up. Besides, if the players snore (打呼噜) when sleeping, they can change their height to make players more comfortable. The smart beds with a remote (远程的) control can change the sleeping and sitting conditions of players according to different situations. Even if a leaf falls on the beds, it can be felt by the smart beds.

The player Tessa Maud in the USA team is a big fan of the beds. She shared a video about the high-tech beds on February 3rd on the Internet. The 18-year-old girl said the beds were so “fabulous” that she would like to get some for her home.

“It’s so comfortable that I slept so well last night,” she said. In the video, Maud showed the bed in its “breathing mode (呼吸模式)”, where two sides of the bed were “lifted up”. She also showed how the bed worked in different kinds of modes.
