The artificial fingerprints 4. (create) by using many common features found in human prints. They work 5. taking advantage of the way smartphone scanners check a fingerprint.

    Here’s an awkward confession (承认): I’ve cried at every job I’ve had. I always find it difficult to___ my emotions. And each time I’ve___ exactly why these emotional moments are considered so taboo (忌讳的). Is it a universal truth that you just can’t cry at work ?

As someone puts it on the internet, as professional women, we’re dealing with the great expectation to “be __ in the pursuit of what sets your soul on fire” while also making enough money to pay rent. __ , my eyes get a little watery just thinking about it. So if crying at work is unavoidable – yet taboo – what is an ambitious young woman to do to __ after one of these embarrassing  incidents?

My usual routine after an in-office __ is to remove my contact lenses, have a massive iced-coffee, and ___it never happened (until it happens again). Clearly, I’m no expert on the right professional response. So I spoke with my personal finance coach, Ashley Feinstein Gerstley, to see if she had any __ for reducing the humiliation (丢脸).

“It’s so __ , but telling yourself not to cry usually __ making you cry more,” she says. “You’re using all your energy to hold it together, but there’s so much pressure that the tears will almost unavoidably come. If you do get upset, it can be helpful to __ yourself from the situation. Take a minute to get it together, and come back ready to have a more composed (镇静的) exchange.”

Maybe there’s some __ in crying. I’ve definitely found that __ the taboo can lead to greater relationships with __. I’ve noticed how tears have helped solve a disconnection or problem that might __ have gone unsolved. To be honest, I’m hoping to recognize, if not celebrate, the rare office cry as a hidden skill for greater future.

    When you sleep, do you ever realize that you are dreaming? If yes, then you have had a lucid dream (清醒梦). 1. Only some people are able to have them. Now, scientists have found ways to help more people to have lucid dreams, Live Science reported.

Denholm Aspy from the University of Adelaide in Australia found that certain skills are key to helping people have lucid dreams.

First, people can train themselves to figure out whether they are dreaming or not. For example, someone may look at a clock, look away, and then look back. 2. Then, they might dream about this trick while sleeping. But in their dreams, the time on the clock may change very quickly. So people know they are dreaming.

Another trick is to wake up after five hours of sleep. 3. During this time, repeat the words, “The next time I’m dreaming, I’ll remember that I’m dreaming.” Then, go to bed again to enter rapid eye movement (REM，快速眼球运动) sleep. In REM sleep, people are more likely to be aware of their dreams.

Scientists found that those who used these tricks had a 17 percent success rate at having lucid dreams. 4.

In a lucid dream, people might study a hobby and then become better at it in real life, according to Aspy. For example, you might learn to play the piano in a lucid dream. 5.

A.Then, stay awake for a while.

B.The time should stay the same.

C.This was far higher than if they did nothing.

D.People learn new skills faster in a lucid dream.

E.It is hard for most people to have a lucid dream.

F.Then, your real-life piano skills might improve.

G.Some people will need more time to fall asleep and have a dream.

    When I tell people I wrote a book with my dad, they usually say, “It must be nice to think of the legacy (留下来的东西) you created with someone who means so much to you.”

This was a beautiful idea, but it was not the way I, or my dad, ever thought about the cooperation. Though we created something we’re proud of, “nice” is not the word either of us uses to describe the process.

“It was more confrontation (对抗) than cooperation,” my dad likes to say. I agree.

When we landed a book deal, we began a writing journey that was more difficult than either of us had anticipated, but also far more rewarding.

For almost three years, we met once or twice a week at my parents’ house and talked daily to plan and outline each chapter. After these meetings, one of us would write a rough draft that the other would build on. I wanted the book to focus on positive vices (不良习惯): such as moderate (适度的) chocolate. However, my dad felt the book should include chapters dealing with things like walking and spending time with family. Ultimately , I saw it his way. He said the book was about more than just good vices. It was about encouraging people to enjoy life in healthy ways.

Writing this book was a reminder that our family members share not only our faults but also our strengths. My dad is smart, funny, critical and caring. He has a strong passion for the truth. I hope I share these great qualities. For this book, he researched each topic with an enthusiasm I’d never seen from him, and he insisted that we constantly question and critically analyze every piece of information – even our own conclusions. He was determined to cooperate with me on a book, not because he couldn’t write one on his own, but because he believed that we could create something better together than we could alone.

I’m not sure if our cooperation led to better writing, but I’m sure it led to a better writing experience. Writing this book was difficult, sometimes more difficult than past projects, but it was never lonely.

    Almost everyone has heard the expression, “the calm before the storm”. It is usually used to describe a peaceful period just before a very stressful situation or a tense argument.

British sailors coined the phrase in the late 1600s; they noted that before certain storms the seas would seem to become static and the winds would drop.

But why is it often so calm before a storm?

Science has given us the answer. According to US infotainment (资讯娱乐) website HowStuffWorks, a calm period occurs because many storms, such as tornadoes and hurricanes, draw in all the warm and humid air from the surrounding area. As this air rises into the storm clouds, it cools and acts as “fuel for the storm, like petrol in a car”.

Once the storm has taken all the energy it can from the air, it is pushed out from the top of the storm clouds and falls back down to ground level. As the air descends (下降), it becomes warm and dry. Warm, dry air is stable, so once it covers an area, it causes a calm period before the storm.

This same process also causes the “eye of the storm” in hurricanes and tornadoes. In these conditions, the calm occurs in the center of the storm because of the strong rotating (旋转的) winds.

The Weather Network has a tip for working out how far away a storm is. First, count how many seconds there are between a flash of lightning and a clap of thunder. Roughly three seconds equal one kilometer. So, for example, if you count nine seconds, the storm is about 3 kilometers away. A good gauge (评估) is that if your count is below 30 seconds, you should seek shelter straight away.

However, due to the complexity of storm system, not all storms are preceded by calm. Given the right conditions, some storms announce themselves with heavy rain and chilling (寒冷的) winds. So, your best bet is to keep yourself updated with weather reports for any predictions regarding a coming storm in your area. That’s the most reliable and sensible way to predict the next display of nature’s temper (脾气).
