【推荐1】We are familiar with the unpleasant results of poor sleep. We may feel tired, anxious and bad-tempered, and everything gets a bit harder to do. But sleeplessness also impairs (损害) parts of the brain that affect our social lives and abilities to relate to other people, according to research by neuroscientist Eti Ben Simon.
In the first study, Simon and his colleagues designed a task where participants would face each other, and walk toward each other. The participant would decide when someone got too close, and they would measure that distance. Consistently, when people were sleep-deprived (睡眠不足的), they preferred others to be farther away.
In a recent study, they asked participants to think about different individuals while their brain activity was being recorded in an fMRI scanner. Then they answered a questionnaire (about daily acts) that explored how likely they were to help others. They found that sleep-deprived people were significantly less likely to want to help others.
They also looked at a database of charitable donations and compared the week of daylight saving time—when people lose, on average, an hour of sleep—to other weeks of the year. In 15 years’ worth of data, they kept seeing that on that week, the amount people donate is reduced by about 10 percent.
Other researchers are looking at similar questions. A colleague published a study that found doctors prescribe (开处方) fewer painkillers during a night shift than a day shift, and that was accompanied by reduced sympathy for their patients.
They’ve found that sleep deprivation reduces activity in what’s known as the theory of mind network in the brain. These are areas that help us think about other people. The larger the impairment, the less they wanted to help other people.
It’s not always easy to restore good sleep. But once we prioritize it, we can really help shift symptoms, mood, anxiety and even the desire to be kind to other people.

【推荐2】We’ve known that sitting for long periods of time every day has countless health consequences, like a higher risk of heart disease. But now a new study has found that sitting is also bad for your brain.
A study published last week, conducted by Dr. Prabha Siddarth at the University of California, showed that sedentary (久坐的) behavior is associated with reduced thickness of the medial temporal lobe (中颞叶), a brain area that is critical to learning and memory.
The researchers asked a group of 35 healthy people, aged 45 to 70, about their activity levels and the average number of hours each day spent sitting and then scanned their brains. They found that the subjects who reported sitting for longer periods had the thinnest medial temporal lobes. It means that the more time you spend in a chair, the worse it is for your brain health, resulting in possible damage to learning and memory.
What is also interesting is that this study did not find a significant association between the level of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise, may not be enough to protect you from the harmful effects of sitting.
It then surprisingly turned out that you don’t need to move much to enhance cognition (认知); just standing will make it. For example, two groups of subjects were asked to complete a test while either sitting or standing. Participants are presented with conflicting stimuli (刺激), like the word “green” in blue ink, and asked to name the color. Subjects thinking on their feet beat those who sat by a 32 millisecond margin.
The cognitive effects of severe physical exercise are well known. But the possibility that standing more and sitting less improves brain health could lower the bar for everyone.
I know, this all runs counter to receive ideas about deep thought, from our grade school teachers, who told us to sit down and focus, to Rodin's famous “Thinker” seated with chin on hand.
They were wrong. You can now all stand up.

【推荐3】Group exercise is one of the most effective ways to improve physical fitness and maintain a healthy lifestyle. Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body. However, studies have shown that when exercise is performed in groups, it’s not only great for improving physical health but for psychological health. It’s an opportunity to be social, release endorphins(内啡肽), and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.
Another beneficial aspect of group exercise is the informational support participants receive from the instructor. Many people fear the gym because they feel lost and don’t want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It’s a great opportunity to learn more about fitness through the clear instruction and supervision of a fitness instructor. If you’re tired of wandering around the gym wasting time and becoming bored, you can attend an upbeat group fitness class that’ll keep your workout on track. Don’t let fitness frighten you!
If you’re serious about wanting to live a healthy lifestyle, it’s extremely important to surround yourself with people who’ll provide you with the proper emotional support. I wouldn’t scold anyone for deciding to party on weekends and in turn I wouldn’t expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!
Surrounding yourself with people who’ll provide you with respect and support can be very beneficial while working towards reaching health and fitness goals. First, decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don’t let negativity ruin your motivation.

【推荐1】On Tuesday, China announced it had grown the first ever plants on the moon, days after landing on the moon’s “far side” Von Karman crater. The cotton seed sprouts (新芽) seemed to have withstood the tough lunar conditions: freezing temperatures, lower gravity levels, and radiation.
But by Thursday, the new cotton seed sprouts had dead already, according to Liu Hanlong, the experiment leader, in a government press conference statement.
After Chang’e-4 landed on the far side of the moon earlier this month, the probe (探测器) was sent a command to remotely water the plants and start the growing process. A tube directed natural light on the surface of the moon into the small container to allow the plants to grow. The probe entered a sleep mode on Sunday, the first lunar night after the probe’s landing.
Professor Xie Gengxin, professor at Chongqing University and chief designer of the experiment, told CNN that it ended after nine days when the control team shut down the power. Xie said temperatures inside the biosphere had grown too abnormal and reached extremes that would likely kill all life, including the seeds and eggs during the lunar night. Xie didn’t confirm why temperatures had risen to levels unbearable for the plants in spite of the measures taken by the research team.
Even though the experiment was quickly terminated, Xie considered it a success. The cotton were the only seeds to sprout, however, and despite many assumptions about the future possibility of moon clothes, the cotton plant’s main purpose this time was to give researchers the valuable data on how to cultivate life in the moon’s tough conditions. The eventual ability to grow plants on the moon could prove useful for long-term space missions, like a trip to Mars. Astronauts could theoretically harvest their own food in space, avoiding the need to return to Earth to resupply.
Aside from the apparent failure of the biological or plant experiment, the rest of China’s mission to the far side of the moon appeared on track as of Thursday. The historic mission is intended to accomplish a range of tasks, including conducting the first lunar low-frequency radio astronomy experiment and exploring whether there is water at the moon’s poles.
Chang’e-4 is the latest step in China’s robotic lunar-exploration program, named after a moon goddess in Chinese mythology. China plans to launch the Chang’e-5 sample-return mission sometime this year.

【推荐2】Although many online personality tests are fun, only a few will really give you insight into who you are and what you are supposed to be doing with your life.
At CareerPlanner. com we believe that each individual （个人），regardless of （不管）race or religion, has a purpose in life, and until you discover what your purpose is, you will not find true happiness, nor true job satisfaction.
This doesn't mean you won't be successful. It just means you won't be happy until you are moving towards your true purpose.
Unfortunately, our school system does very little to help students discover their true career. This is where online personality tests and career tests can help.
Online personality tests and career tests can help you better understand what type of work you should be doing to achieve job satisfaction, happiness, and success.
Personality tests are most useful in giving you insight into “how" your personality compares to others and “how" you like to work.
In particular, if you frequently experience difficulty working with others, or getting their support and cooperation, a really good personality test would show you how to get along better.
While personality tests are very useful at showing you how you like to work and how you like your work environment, they are not really designed to show you "what" type of work is right for you.
That is where Career Interest Tests come in. Online Career Tests, such as the CareerPlanner.com offers will help you discover what your true interests are, and what type of work you will be passionate about.
But back to personality tests. The most well-established personality tests are the Myers-Briggs Type Indicator R, and the Enneagram.

【推荐3】Although onions taste delicious, watering eyes come with the process when you cut them up. Thankfully, Good Housekeeping has suggested some tips to prevent yourself from crying while trying to cut up an onion．
According to the findings from the Institute, putting onions in a fridge 30 minutes before cutting can prevent the annoying hurt, as the cold stops tear-jerking (催泪的) gas from being produced.
Another way to reduce the gas released by the onion is to put it in water for a while. Good Housekeeping recommends:“ Cut the end off the onion and then put it straight into a bowl of water. The water will draw out the acid making you tear up less when you cut it.”
When an onion grows, it mixes with sulfur (硫) in the soil to create a special mineral acid. When the onion is cut into pieces, it reacts and creates a gas. As it reaches your face, this annoying gas causes the eyes to produce tears．
The root is where the gases are most concentrated, so it is recommended that this part of the onion be left on as you cut it to avoid uncomfortable eyes. Do this by cutting the vegetable in half down the middle to create a flat surface. Then, place the onion with its flat surface down and cut it towards the root．
Also, to reduce the gas’s effect on your eyes, cut it next to a window or near a fan so the gas is blown away from your face. And take care to use a sharp knife; this will make it easier to move through the vegetable, causing fewer cells to be broken and less gas to be released as a result．
1. Refrigerating the onion before cutting can ．| A．change its taste |
| B．make it easier to cut up |
| C．avoid the appearing of the gas |
| D．help the gases mix more quickly |
| A．Some acid mineral is lost． |
