1 . Some people have a dependency on an afternoon nap.     1     It can also help them feel more alert (机敏的)for the afternoon ahead. Even Boris Johnson supposedly favors a power nap during his work day. Winston Churchill, Albert Einstein, and Leonardo Da Vinci were all famous nappers.

Napping is a great way to feel more rested and alert-and some research shows it car benefit our cognitive function.     2     If you need to be alert right after waking up, so-called "power naps" of 10-30 minutes are recommended.

While short naps are great for increasing energy, longer naps are more beneficial for learning. According to the research, they improve activation of the hippocampus—an area of the brain important for learning and memory.     3    

    4     It's possible that they help the brain clean up sleep-inducing (诱导睡眠的)waste products that would otherwise hold up brain activity, and that they refill the brain's energy stores. Short naps may also help improve your attention by letting particularly sleepy areas of the brain recover, hence preventing instability in the brain's networks.

Although napping has many positive short-term effects, they are not recommended for people who suffer from insomnia（失眠症）. Because naps decrease sleepiness, they may make it harder to fall asleep when going to bed in the evening.     5     For instance, if the best performance is needed instantly afterwards, don't nap, as it may take some time to fully wake up.

5 . There’s a child-like joy that comes with ordering something online — whether it be clothes or kitchen facilities. We sit refreshing the postal service to see when our items will arrive, and we become overly excited, hopeful and anxious.

Ryan Howes, a clinical psychologist from Pasadena California, has interpreted this phenomenon as “anticipatory pleasure”. “A lot of people believe that placing that order and waiting for it does feel good. This is why people look forward to dinner reservations, hair appointments and yes, receiving packages,” he says.

But it’s not the purchase itself that brings about this happiness. Experts say there’s something about the anticipation of waiting that is exciting for those in need of change in their lives. “It can be helpful to anticipate good things in the future, ’’says Ryan Howes. “Waiting for a parcel can serve as a temporary distraction (分心) from the dullness of your life because it gives you something new to wake up to and get excited about.”

However, anticipatory pleasure isn’t always a good thing. While waiting, many are worried about their items arriving on time, appearing broken, or simply not living up to expectations. Even when our package finally arrives, you’ll find that initial excitement has probably waned. Howes cautions that comfort shopping is only a temporary fix. It’s just a distraction from bigger problems, but it hasn’t done anything to change the bigger problems. It only helps you escape from them temporarily.

“Many people often seek external solutions, such as luxury purchases or alcohol, as a way of feeling better quickly. However, a healthier long-term curing mechanism is to look inward and appreciate your life with gratitude. Real pleasure comes from taking action rather than wait passively.” Howes says.

So the next time you feel the urge to order and track something online, chew over it.

As you achieve confidence, and find little moments of confidence coming closer and closer, all the things you desire will come to you easier than you ever imagined.

8 . On a sunny afternoon, Andreas Fath climbed out of a river in Paducah. A small crowd was on hand to witness his setting a new world record. This man had just finished swimming the entire length of the Tennessee River—1,049 kilometers. And he did it in just 34 days!

As a chemist from Hochshule Furtwangen University, the 52-year-old man had taken on this swim for science. His primary goal was not to get his name into Guinness World Records. What really drove this swim was a desire to make people aware of the seriousness of water pollution.

Fath’s crew included his family. Martin Knoll, who helped organize Fath’s swim, also took par t. Knoll is an environmental scientist at the University of the South. He describes this swim as a vehicle for getting people interested in water quality and how we pollute water without realizing it.

It took Fath 34 days to swim the river’s length. Along the way, his crew took measurements of the water’s temperature and pH. They also recorded weather and the speed of the river’s currents (涌流). As for the Tennessee River, they collected daily water samples. A small plastic device attached to one leg of Fath’s wet suit sampled the chemical pollutants (污染物) through which he swam. Finally, Fath’s goal is to use such data to know what on earth results in water pollution. Then he wants to find ways to keep those chemicals out of the water.

Back in Germany, Fath and his students have finished examining their data. They plan to publish their findings soon. Identifying materials that hide in the river isn’t only important for the animals that live there. “It’s also a way to protect human health,” says Fath.

10 . I have met many people, but I will always remember my teacher, Mrs. Lawrence.

I will remember Mrs. Lawrence for her good character. She is always nice and helpful to the students. She will take every chance to praise the students that are not so good in class. I wish I could have the same great character as her.

I will always remember the great moments when we are together. Once I stayed in her room for several days and it was really enjoyable. I love to listen to all the stories and things about her.

I also like her creativity(创造力). We don’t like boring books, music, pictures, students and so on. She teaches us about these boring things in ways that we like. I also enjoy the way she asks us to be quiet while she is talking at the front of the classroom. She will give us a lovely little flower when we do something well. The student that has got the most flowers at the end of the month will receive gifts like pies, drinks and chips.

I will never forget Mrs. Lawrence. She has taught me to always be a person of good character, even if I'm angry. She has taught me just to have fun and not to worry. She has also taught me to be creative and enjoy what I do. That is why I will remember Mrs. Lawrence forever.
