How strong are you?

    That is a hard question to answer, whether you are a man or a woman. But, really , I want to ask how do you define(给...下定义)your strength? How do you know your limits?{#blank#}1{#/blank#} When push comes, we often discover that we are much stronger than we think.

    What is Strength?

    Strength is not always about pure physical strength.{#blank#}2{#/blank#} It is about the ability to get things done. I know some people who are intellectually strong, but they get very little done in their jobs. And I know others who find work challenging, but they make it by strong drive and hard work. They possess inner strength.

    Self-Imposed Limits

    What I have observed is that most people set their own limits. They limit their output based on self-framed limits (自我设定的限制) of their abilities and strengths. Sometimes these boundaries are based on past experiences. Sometimes they are based on self-imagined abilities.{#blank#}3{#/blank#}So, how do we break through these limits? How do we get stronger?

    {#blank#}4{#/blank#}

    If you want to be stronger, you have to push your boundaries. Pushing it is what it takes to increase your limits. In the gym, bodybuilders discovered this long ago. The same principle is true when it comes to inner strength.

    Want to test your limits? Push yourself. Test your self-framed limits to see how accurate they are. Make sure your goals are slightly beyond what you think can be achieved.

    You Are Stronger Than You Think

    Most people underestimate(低估) their strength.{#blank#}5{#/blank#}Test your limits. Push yourself to find your true boundaries and define your strength.

    When you discover how much you've really got, you may surprise even yourself.

A. Certainly, it is about willpower.

B. Sometimes these limits are based on nothing.

C. How do you know just how much you've got?

D. Pushing It

E. As you go through your day, challenge your ability.

F. How can we train our mind and make it stronger?

G. Strength is a combination of physical and mental ability.

    A conversation with a good listener is like a good meal—we walk away feeling satisfied and happy.{#blank#}1{#/blank#}Here are 4 ways to make your conversation partner feel like you're fully tuned in to their personal radio station.

    {#blank#}2{#/blank#}

    Making your conversation partner feel safe starts with two things: an open mind and keeping judgment to yourself. Just as immersing（沉浸）yourself in a novel requires suspension of disbelief, immersing yourself in listening requires suspension of opinions or advice. While judgments may appear into your head, set them to the side.

    Ask questions to follow your natural curiosity.

    When you're interested, ask questions.{#blank#}3{#/blank#}Ask for examples. Ask for details. Following your natural curiosity by asking questions not only shows you are listening and interested, but almost always produces an interesting story.

Listen with your whole body.

    In many a kindergarten classroom, teachers emphasize something called “whole body listening”. It goes like this: use your eyes to watch nonverbal（非语言）, your brain to think about what is being said, your heart to feel emotions» and keep the rest of your body quiet to show respect. But many of us lose it over time, especially as life gets busy. The result? We often try to multitask while listening.{#blank#}4{#/blank#}

    Validate（使生效）with simple phrases.

    Keep in your back pocket some validating words and phrases to show you've heard someone.

    “Of course.” “That makes sense.” “Naturally.” “Clearly.” “For sure.”{#blank#}5{#/blank#}In conversation, combining those little phrases: “Of course you feel that way.” or “That makes total sense.” doesn't necessarily convey agreement, but it does convey something even bigger： acceptance.

A. Create safety.

B. Devote yourself to listening.

C. It's appealing to talk about your own experience.

D. We half-listen while getting things done or staring at a screen.

E. Think like a journalist and ask what, when, where, why or how.

F. But being a good listener goes way beyond just not interrupting or nodding your head.

G. All of these statements confirm a person's experience or feelings as worthy and accepted.

    A latest research led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Hou. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analyzed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we're also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors, "explained Prof Hou.

    There are many programs for high school students today that help lonely teenagers deal with loneliness. However, loneliness is not only a problem for teens but also an important and rarely acknowledged one in the elderly.

    In Britain, Tracey Crouch was appointed to be the first Minister of Loneliness in order to address the problems caused by loneliness. This is the first time such a position has been created.

    In Britain, there are around 9 million people who say they are lonely frequently. In Germany, a study conducted by Ruhr University Bochum found that 20 percent of people over the age of 85 felt lonely, and 14 percent of those between age 45 and 65 felt socially lonely. In the United States, more than 25 percent of the population live alone, more than 50 percent are unmarried.

    Loneliness is generally associated with heart disease  overweight, and anxiety. Additionally, the stress from loneliness can cause your cells to change on a molecular (分子) level that reduces its abilities to defend your body against diseases. In fact, doctors believe having feelings of loneliness is equivalent to smoking 15 cigarettes per day in regard to its effect on health!

    In Britain, the new Minister of Loneliness will help introduce government policies on the problem and fund a charity—an organization for helping people in need, to devote their efforts towards aiding loneliness. There are charities that link lonely seniors to high school students in order to give them a line of communication whenever they feel lonely!

    The possibilities for the new Minister of Loneliness are endless. For example, she can provide education services to household businesses so that they can identify lonely customers if they see one. Loneliness fits into the category of being a social problem that must be monitored by the entire community in order to help those in need. Therefore, government involvement in medical services and care for seniors and others is vital for happy seniors.

    A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.

    Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks.

    The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.

    When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.

    It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”

    The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.

You've probably heard it a dozen times by now. But here it goes again: Sleep is important. Your mental health and immune (免疫时)system are connected to your sleeping habits. So are your grades, a new study finds. Sleep accounts for nearly one-fourth of the difference among students' grades in a class. So even if you spend hours studying for a test but get too little sleep, you might still do poorly.

Typically, people's sleep schedules are messy and can not be known in advance. Professor Jeffrey Grossman of Massachusetts Institute of Technology in Cambridge wanted to see if sleep links to people's learning performance even when a study was done with people who kept such true-to-life schedules at home. So he turned to Fitbits, which can check how long people sleep and how frequently they wake up. And the researchers looked for 100 students. They focused on these students' sleep patterns in the days and weeks before exams and then compared them to these students' test scores.

"How much time a person sleeps the night. before an exam doesn't affect that person's grade," Grossman says. "A student who sleeps 7 hours every night will do better than a student who sleeps 7.5 hours one night and 6.5 hours another night."

"It's important for people to know that if their Fitbits tell them that they have terrible sleep, that may not actually be so," Michael Scullin, a sleep scientist at Baylor University says. Grossman also raises this point. Fitbit, Inc. makes this advanced tool. But it doesn't share how its tool works. This leaves a question about whether the tool is really correct when checking a student's sleep. Even so, Scullin emphasizes that there are enough data supporting ties between sleep and how well someone performs.

"Students need more sleep and less late evening use of phones and other screens. Even with after-school activities and schoolwork, they need to get enough sleep," Grossman says.
