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

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones."The Living-room television is replaced and gets planted in the kid's room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices-we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TV's with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放) more than doubling during the 1992 to 2007 window.

    So what's the solution(解决方案)?The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tables instead of TVs and desktop computers could cut energy consumption by 44%.

Preparing Cities for Robot Cars

    The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

    While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

    Do we want to copy—or even worsen—the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport—an unwelcome side effect researchers have already found in ride-hailing (叫车) services.

    A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

    Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

Ways to be safe in school

    School safety issues involve more than violence. It may also address such concern as natural disasters, illness, fire and local emergencies. {#blank#}1{#/blank#}

    Have a plan

    Teachers and students should know where to go and what to do in case of a school security situation. {#blank#}2{#/blank#} Schools can also post guidelines in each classroom with simple pictures pointing out emergency exits, fire extinguishers (灭火器), and other emergency equipment.

    Screen visitors

    {#blank#}3{#/blank#} Give school visitors temporary badges (证章) to identify them. Install cameras at all entrances and restrict access as much as possible. Ask teachers and hall monitors to stop anyone in the halls without appropriate identification.

    Panic buttons

    Provide teachers with panic button in classroom so they can ask for help immediately. Provide clear and brief instructions about use and immediate response when .started. {#blank#}4{#/blank#}

    Establish a hotline

    Establish a hotline so students can report crimes and threats anonymously (匿名地). Post the number in obvious locations so students can see it on a regular basis. {#blank#}5{#/blank#} Establish a student disciplinary committee, and develop peer counseling programs for newcomers and victims of bullying (欺负).

A. Teachers and students should be certain that immediate help will arrive.

B. Visitors are not allowed to enter schools.

C. Students may report crimes and threats more quickly without being identified.

D. Require that all visitors enter the security office and explain why they are there.

E. It is said that about 16,000 students die in school accidents every year in China.

F. So what can we do to make the school a safer place?

G. Just as schools practice fire drills, they can conduct safety drills.

A seismic (地震的；重大的) shift in climate science might be heating up.

New research shows that sound waves, produced by earthquakes can be used to measure temperatures in the ocean which traps 90% of the heat Earth absorbs from the sun，making long-term changes in ocean warmth, a major factor in how the world might respond to global warming.

For years the main approach of measuring ocean temperature has been Argo, an array (阵列) of 4000 automatic floats, which drifts the globe, sampling ocean water and measuring its temperature. Yet Argo measurements stop at 2000 meters.

The new technique called "Seismic Ocean Thermometry", would be especially useful in detecting long-term changes in ocean temperatures deeper than Argo's reach.

"Ocean Acoustic Tomography", the basis for the current research, was first tested nearly 30 years ago. The initial studies created sound waves artificially, basically increasing the volume on giant underwater speakers. Scientists measured the sound's travel time from the speakers to receivers thousands of kilometers away. Because ocean temperatures affect the speed of the waves, the researchers could calculate average temperatures along their paths. But some believed the noise was a threat to ocean life and the technique never took off.

The new study instead uses a natural sound source for investigation: earthquakes making a low, continuous noise beneath the seafloor off the coast of Sumatra that drum up sound waves in the ocean. On the shores of the Chagos Islands in the East Indian Ocean, between 2005 and 2016 Seismic Station Diego Garcia recorded seismic waves produced by those earthquakes. Some of those waves created physical changes in land and sea as they traveled. Others were sound waves or T waves that moved through the deep ocean, delivering valuable data about ocean temperature.

12 years of data coupled with mathematical models pointed to a temperature change of roughly 0.044 degrees per decade, a trend larger than those predicted by Argo. The findings suggest that Seismic Ocean Thermometry is a feasible method to measure changes in ocean temperature. Further data from other regions of the globe and other timeframes would help improve the warning models and predictions.

And in future studies the researchers plan to listen directly for sound waves, using a network of hydrophones, microphones which detect sound waves under water. Sound waves set the tone for a deep dive into our warming oceans even if they fail to reach 60000 miles under the sea?

We're often told "laughter is the best medicine".Laughter is ancient and instinctual,and a fundamental part of everyday life—something most of us enjoy naturally.There are comedy channels on TV,comedy festivals and our favorite funny friend who's sure to get our giggle on.

So why do we need laughter experts?Surely they're for people who can't laugh for whatever reason.However,while the ability to laugh is innate,the decision to activate and use it to its full ability is a choice.

When life gets stressful;illness creeps in;relationships are put to the test or we're struggling financially,there's rarely much to laugh about.So,we don't.Yet turning into the lighter,more humorous side of life,and activating one's "laughter self" is critical to mental health.Rather than waiting for something funny to happen or for life to be a bed of roses,we can transform our emotional state by tapping into our laughter and humor resources.This helps create distance between us and our pain and improve our moods and resilience(恢复力) to stress.It provides relief and release from some of the stress that has embedded in our bodies and minds,freeing ourselves to power forward,even a little.

Ironically,because laughter is an innate and largely unconscious behavior,it's rarely given much thought.As it's seldom thought about,it can't be that important.

Wrong.If laughing is a more complex behavior,my belief is people will pay greater honor to it,rather than something to laugh off.It's actually one of the most complicated things our bodies process.It is a vocal means of communication before language forms and the brain has fully developed.The vast majority of us maintain the ability to laugh until our final curtain falls,even amid declining cognitive function.

Turning toward the healing power of humor and laughter assists with personal and professional resilience,performance and overall well-being.No joke.
