Motivate yourself to be on time, and trick yourself into punctual(准时的) habits, with these tips.
Never explain why you're late. If you don't allow yourself to make excuses, you'll stop letting yourself off the hook. And you'll realize how often you've been handing out reasons as if everyone didn't already know them. There's a classic headline, "Woman Constantly Treating Herself for Once." Don't be "Person Constantly Delayed for This One Good Reason." 1. That's the decent thing to do.
2. If you're paid hourly, find out how much less you make when you clock in late. If you take more expensive modes of transportation, calculate the cost difference. See how much you spend each year on lateness.
Imagine being late to meet someone. 3. Think about the worst-case reaction they could have, whether that's frustration or a "not mad just disappointed" that makes you feel like a real dick. Now visualize being early. Think about the peace of mind as you wait for the other person. Think about standing from your seat and warmly greeting them, grandly forgiving their own lateness.
Think about your most chronically late friend or colleague. Gin up all the frustration you've ever felt with them, all the disdain. Wow, kind of harsh on your friend, but now think about other people feeling that way toward you. 4.
Plan exactly what you'll do on your phone while you wait for everyone else to show up. 5. Get excited, not for the thing you're heading to, but for those five minutes alone before it starts.
A. So, avoid being late.
B. Feel the shame and the panic.
C. Promise not to be late frequently.
D. Calculate the expense of your lateness.
E. You will never be forgiven if you are often late.
F. Instead of focusing on causes, apologize for the effect of your lateness.
G. That’s the free time, like playing a mobile game with zero guilt.
Most squirrels don’t hibernate(冬眠). Instead, they store food for the cold season and spend the winter in their nests. But the 13-lined ground squirrel, one species of squirrel in the U.S. Midwest, is not the case. For up to 8 months, the tiny mammals won’t eat or drink anything at all and the heart rate, metabolism(新陈代谢), and body temperature dramatically drop during their long rest, which is similar to bears and other hibernating animals.
To find out how the hibernating squirrels hold back their thirst, a powerful force that could potentially wake them up, and researchers measured the blood fluid of dozens of squirrels. Generally, a high blood concentration(血液浓度) makes animals, including humans, feel thirty. The sleeping squirrels' blood concentration was low, preventing them from waking up for a drink. Even when researchers woke up the torpid squirrels, they wouldn’t drink a drop until the team artificially increased the concentration of their blood serum.
Next, the researchers wanted to know how the squirrels’ blood concentration dropped so low. Perhaps the squirrels drank a lot of water before hibernation to dilute(稀释) their blood, the researchers thought. But when they filmed squirrels preparing for their winter snooze, they found the animals actually drank less water than they normally did.
Instead, chemical tests revealed the squirrels regulate their blood concentration by getting rid of electrolytes(电解质)like sodium and other chemicals like glucose and urea and storing them elsewhere in the body (possibly in the bladder), the researchers reported last month in Current Biology. The finding could also explain how other hibernating animals stay containing water.
This new knowledge might one day help humans with conditions such as diabetes(糖尿病), or astronauts who have launched on long space flights. Unfortunately, even if people can figure out how to drop their blood concentration, it’s unlikely they’ll ever be as cute as sleeping squirrels.

C.low body temperature D.high heart rate
3.Hibernating squirrels adjust their blood concentrations by_____________.
A.Drinking much water before hibernation
B.Not eating anything during hibernation

Online live streaming(直播) is big business nowadays, making huge profits and attracting hundreds of millions of viewers. In addition to adults, this rapidly expanding industry is now drawing underage live streamers, who are not of legal age. According to a report by the Sina Weibo Data Center, live streamers aged 11—16 accounted for 12 percent of all streamers in China. The figure has been rising still, while streamers are getting younger.
It has been found that a large number of underage streamers are drinking, smoking or even exposing to attract viewers. In the best case, live streaming will affect children’s schoolwork and waste their precious youth. In the worst case, they will develop bad values and an improper outlook, which will damage their future.
“Webcasts (web broadcast) are suspected of having a hotbed of improper program. Particularly, the involvement of underage streamers in this industry is making the situation more complex” said Mao Jianguo from Southern Metropolis Daily.
Some legal experts recently issued a report on protection of the children in the cyberspace(网络空间), suggesting that those under 14 should be restricted from independently live streaming and posting videos online.
However, it is unwise and impossible to totally reject all underage streamers but it's necessary and even urgent to standardize the underage webcast sector.
Fortunately, some webcast companies have said that they will not allow streamers under the age of 18 and online live streamers must register by using their ID. However, the reality is that many underage streamers choose to avoid that by using the IDs of adults, who also go through the face scanning required for conditions. All this means that to block underage streamers from webcasting, it’s not enough to depend on their self-discipline.
Parents should tell their children about the disadvantages of getting involved in live streaming so that children develop an objective attitude toward live streaming. Adults should not lend their IDs to children to register for live streaming. And the watchdogs must patrol(巡逻) webcast platforms more actively and remove all unauthorized videos of underage streamers.

I’m going to be completely honest. I have no idea how I ended up with this opportunity, I have no idea what I’m doing, but I am very happy to be here.
Last summer a friend tagged me in a Facebook post from BBC Earth and encouraged me to apply to the BBC Presenter Search 2018. The assignment was easy and hard, make a video shorter than 60 seconds where you talk about something in science you think is cool. Simple concept, but for me it was challenging as I want to talk about bryophytes(苔藓植物) forever (which is slightly longer than 60 seconds).
So I decided to make an attempt. I was going to make a 60 second video about sphagnum(水苔), commonly known as peat moss and uncommonly known as an unsung climate hero. Sphagnum is the plant genus that holds the most carbon in the world, it slowly builds up its carbon storage over hundreds of thousands of years and if undisturbed, they never let go of the carbon they gathered.
Making a short video on this was hard because I wanted to include everything. And it became even harder as I had no one to hold the camera. I tied my camera to the scrawniest little tree, swinging in the wind as a bird tried to chase me away from the mud. This chaos ended up as the video “Why sphagnum is awesome” on my channel. I submitted the video, but didn’t dare to write in the description section of the video that it was a submission, because I never imagined that I could win!
But I did.
I waited two months before I could tell people that I had won the search, and when the news came out, I received the most attention I’ve had in my entire life.
No matter your background, whether you want to pass the time or pass an exam, I really hope you enjoy the video!
