    A group of cultural calendars, with creative designs, informative content and delicate printing, were hot sellers last year and now posting photos of the calendars has become a new fad on social networks. Many people posted photos of their cultural calendars with their comments to arouse memories of traditional knowledge. Though the cultural calendars are a return to traditions, designers are racking their brains to make the calendars appear more attractive.

Quick tips for better time management

    Are you a good time manager? If your answer is “no”, here are some tips on how to be a better time manager:

1). Create a daily plan. Plan your day before it starts. The plan gives you a good description of how the day will go on. That way, you will be ready to deal with most of the things you meet. {#blank#}1{#/blank#}

2). Focus. Are you multi-tasking so much that you're just not getting anything done? {#blank#}2{#/blank#} Only focus on what you're doing. You'll be more efficient that way.

3). Stay away from your time wasters. What takes your time away from your work? QQ? Email checking? {#blank#}3{#/blank#} One thing you can do is make it hard to check them — remove them from your browser quick links.

4). {#blank#}4{#/blank#} Don't take on more than you can deal with. For the distractions that come in when you're doing other things, give a firm no. Or do it later.

5). Decide to be early. When you prepare to be on time, you'll either be on time or late. {#blank#}5{#/blank#}However, if you decide to be early, you'll most likely to be on time. For appointments, try to be early. For your deadlines, meet them earlier than required.

A. Learn to say “No”.

B. Most of the time you'll be late.

C. Great ways to know your time spent.

D. Cut off when you need to.

E. Stop checking them so often.

F. Your job for the day is to follow the plan as best as possible..

G. If so, focus on just one key task at one time

    Electric devices can seem like a “third party” in some relationships because some partners spent more time on them than with each other.

    When Amanda Gao, a 26-year-old white collar worker in Beijing, went to a hotpot restaurant with her boyfriend on Friday night several weeks ago, she expected that they would have a good time together. To her disappointment, however, it did not turn out that later. As soon as they were led to their seats and she began to order dishes, he buried himself in his mobile phone.

    “It seemed that his phone was making its way between us. A date that should have belonged to us turned into one where my boyfriend dated a third party and I felt left out.” Gao said. Some people, like her, have found electronics have been sabotaging(破坏) their romantic relationships.

    A study, published in the journal Psychology of Popular Media Culture, in April, 2017, questioned nearly 200 college aged adults who were in committed(真诚的) relationships to report on their and their partner's smartphone dependency. The results showed people who were more dependent on their phones were less sure about their relationships, and people considered their partners excessively(过度地) dependent on their devices were less satisfied in their relationship.

    Lin Yuan, a relationship advisor in Beijing, noted that as more and more electronics come out and spice up people's lives, they are at the same time becoming a third party in relationships, especially for young people.

    Lin said she knew of some people who suggest that electronics should be kept out of bedrooms, which she considered challenging and hard to be put into practice for most couples. She recommended that if people are feeling neglected in their relationship, they need to respectfully let their partners know their feeling. “Communication is always the best and the most efficient way.” she said.

There're plenty of fresh fruits and vegetables available in local markets.But while those red juicy strawberries look  fresh,consumers have no way  of knowing how  long the  fruit  can be  stored  at  home.The  same  goes  for distribution centers and supermarkets.

Now,the food technology startup OneThird,located in the Netherlands,is looking to change that with an infrared (红外线)scanner that can accurately predict how long fresh fruits and vegetables will last.The startup is named OneThird because one-third of food is wasted due to spoilage(变质)every year.

The startup's founders were inspired by a UK company that uses this type of technology in the medical field and decided to see if it was applicable for food."I looked at the challenges in the food-supply chain and found out that 40 percent of food waste is fresh produce.One of the biggest causes of waste is that nobody knows shelf life." founder and CEO of OneThird,Marco Snikkers said.  Quality inspections at farms and distribution centers are done manually(手动地).An inspector checks the fruits and vegetables and makes notes about the size and quality.Then the food is sent to consumers without considering travel time or how long the produce will remain usable.

Using the infrared scanner at the distribution center means that inspectors can use the information to approve shipments that will ensure the produce can be distributed on a timely basis.This means that a shipment of ripe tomatoes will not be sent long distances away.

OneThird's scanner combines the technology of optical scanners,image modeling,and Artificial Intelligence to provide accurate shelf-life predictions.  The startup found that the technology can reduce up to 25 percent produce waste that was caused by spoilage. "Global food waste has an enormous environmental impact;reducing global food waste cuts global greenhouse gas emissions and promotes global food security,"said Jacob Smith,a climate expert from the University of Maine.

Deep below the ground, radioactive elements break up water molecules(分子), producing substances that can fuel subsurface life. This process, known as radiolysis(辐射分解),has supported bacteria in tiny cracks filled with water on Earth for millions to billions of years. Now a study published in Astrobiology shows that radiolysis may have supported life in the Martian subsurface. 

Dust storms, rays in the universe and solar winds ruin the Red Planet's surface. But below, some life might find shelter. "The best survival habitat on Mars is the subsurface," said Jesse Tarnas, a planetary scientist at NASA, Examining the Martian underground could help scientists learn whether life existed there. And the best subsurface samples available today are Martian meteorites(陨石) that have crash-landed on Earth.

Tarnas and his colleague looked at the minerals on the Martian surface and how many radioactive elements there were, using satellite and rover data, They used computers to simulate(模拟) radiolysis to see how efficiently the process would have generated life-supporting hydrogen gas and other chemical substances. They reported that if water was present, radiolysis could have supported life for billions of years and perhaps still could today. 

Scientists had previously studied Mars radiolysis, but this marked the first estimate using Martian rocks to see how habitable Mars underground might be. Tarnas and his colleagues also evaluated the potential richness of life in Martian underground.They found that up to a million bacteria could exist.in just one kilogram of rock, The most habitable seemed to be the southern highlands of Mars, which is the most ancient area on Mars, according to Tarnas.

"Underground life would require water and it remains unknown if groundwater exists on the planet," says Lujendra Ojha, a planetary scientist at Rutgers University. Determining whether the Martian, subsurface contains water. will be an important next step, but this investigation helps to motivate that search, Ojha says, "Where there is groundwater, there could be life."
