The college entrance examination is just around the corner. Homework and tests will keep many of you up late at night, and you may plan to make up for your lost sleep during the weekends. {#blank#}1{#/blank#} is it useful? A study published in the journal Current Biology completely has changed {#blank#}2{#/blank#} people used to think. It shows that the habit of sleeping in on weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}3{#/blank#} (bad), it may damage your health.

Starting a club of some kind at school can be difficult. But with a good idea, some active friends, and the right knowledge, you can pull it off. {#blank#}1{#/blank#}.

Decide whether you really want to start a club. Once you have strong enough support from your friends and fellow students, you're ready to go.

{#blank#}2{#/blank#}. Find an advisor for your club. Pick someone who will help you organize events for your club.

Find a place. {#blank#}3{#/blank#} If you want to do this,  talk to your headteacher to apply (申请) for a classroom.

Decide when to meet. Decide how often your club should meet, and then pick a convenient time and day when most club members will be free.

Advertise your club at school. Make bright, colorful informative posters (海报) that will attract attention. {#blank#}4{#/blank#}.

Plan volunteering events. You can decide on events yourself, or hold a meeting to get your club's opinion. {#blank#}5{#/blank#}

Have fun. What's the point of having a club if it's no fun? Don't take yourself too seriously and be sure to have a sense of humor.
 

Earlier this year Rodney Smith Jr. made headlines when he drove eight hours from his home in Huntsville. Alabama, to cut the lawn for an elderly soldier in North Carolina who couldn't find anyone to help him with his yard work.

That wasn't the first time the twenty-nine-year-old Bermuda native had gained such attention. To do his good deeds, Rodney often finds leads for those in need through social media.

Back to one August afternoon in 2015, Rodney Smith Jr. was driving home. That's when Rodney saw an elderly man struggling to mow his lawn. He would take a couple of shaky steps, using the handle to stabilize himself, pause, then slowly push the mower again. Rodney decided to help. Mr. Brown thanked him greatly, and Rodney went home feeling satisfied.

Sitting at his computer to do his homework, Rodney couldn't get Mr. Brown out of his mind. There must be many Mr. Browns out there. He went online and posted that he would mow lawns for free for senior citizens. Messages flooded in.

One day a cancer-battling woman said she wasn't having a good day. Rodney decided to do more than mowing lawns. After he finished mowing, he knocked on her door. "You're going to win this fight, Madam", he said. Then he asked folks to pray for her on social media.

Word of Rodney's mission spread. A grandmother in Ohio said he'd encouraged her 12-year-old grandson to mow lawns. He got a letter from a seven-year-old boy in Kansas. "Mr. Rodney, I would like to be a part of your program, and I'll make you proud," he wrote.

That gave Rodney an idea. In 2017, he decided to establish a programme Raising Men Lawn Care Service to make a national movement for young people. The kids learn the joy of giving back.

Yard work seems like a small, simple thing, but taking care of the lawn means a lot to the people they do it for. "When we mow their yards for free, they can use the money for healthcare and food etc. It means more than you would think," Rodney said.

The Netherlands is the only country in the world with more bicycles than residents. By 2022, the Netherlands has had a total of about 23 million bicycles, with an ownership rate of 1.35 bikes per person. One study published by the National Institutes of Health (NIH) reports that in the Netherlands cycling prevents about 6,500 early deaths each year, and that Dutch people have 1.5 years longer life expectancy (预期寿命) due to cycling. 

"The time spent cycling was about 74 minutes per week for Dutch adults aged 20 to 90 years old. The time was fairly stable over adulthood and reached its apex in the early days of retirement, in one's 60s. The death rate reduction, which was a direct result of the average time spent cycling for a certain age group, was therefore also the highest among the seniors who just retired," said Jeremy Smith, an expert from NIH.

What is it that makes cycling so beneficial? Obviously, cycling is a form of exercise. It is a great form of cardio (有氧的) exercise, which gets your heart pumping and helps strengthen the heart muscles. Doing cardio exercise may also help lower your blood pressure. 

Furthermore, solid evidence proves the link between cycling and better thinking skills. Even younger adults claim that a bike ride helps shift their thinking to a higher level — and research backs them up. In one small study, young men are required to cycle for 30 minutes every day for 3 weeks. They also completed a series of cognitive (认知的) tests before and afterward. After cycling, they scored higher on memory, reasoning and planning, and they were able to finish the tests more rapidly than before.

Besides all the benefits mentioned above, cycling, as many Dutch put it, is a way of life. In their simplest form, bikes are tools for travelling. But they're so much more. They are cognitive improvement, environmental protection, satisfaction and an expression of freedom. They bring people of the same passion together and connect them to a greater journey of life.

They talk about the straw that broke the camel's back, but really it should be the password that wiped out my memory bank. 

I was going along fine -with instant recall of my bank PIN (密码)，my mobile phone number and the date of my cousin's birthday before I downloaded a gas station payment app for its new customer discount. It asked me to create a password. When I typed in "gas 1", it was rejected for not being complex enough. I tried again: "IHateHearlessOilCompanies@". But that was too long and didn't include "at least one number". But here is the thing: as soon as 1 added the fresh password into my memory, I instantly forgot all the others. My brain had hit its limit for passwords. I now know nothing. 

I had entered some passwords in a notebook. Of course, I didn't write down the actual passwords, in case it fell into the wrong hands. Instead, I masked them in a way that only a family member could figure them out. For example, I combined my bank PIN with our postal code, then added it to a list of phone numbers. It would fool even Albert Einstein.

Maybe we need a system like the one we use to remember people's names. You know, you form an association between a person's characteristics and their name by whispering "Skinny George, Skinny George" in heart after meeting them. The risk is that, upon seeing him, you'll burst out the phrase. "Skinny George" might not mind, but it's possible "Boring Betty" will. As for remembering passwords as you change them, you could simply use the first and last letters of your favorite singer's greatest hits, together with the year of their release.

Maybe I'll try that one out- -but only after describing the system in the notebook. Then I'll hide it in a place so secret that I'll never remember where it is. 

Here are two athletes who are masters in their sports and also set{#blank#}1{#/blank#} good example for others.

Lang Ping, as a player, brought honour and glory to her country. As a coach, she led the China women's volleyball team to {#blank#}2{#/blank#} (medal) at world championships and the Olympics. When the Chinese team was preparing for the 2015 World Cup, her {#blank#}3{#/blank#} (determine) was tested. The team she had built was falling apart. Two of her players had to leave.{#blank#}4{#/blank#} (face) the challenge, Lang Ping didn't lose heart. She knew that her young players could win{#blank#}5{#/blank#} they worked together as a team. Two weeks later, they were world champions.

Michael Jordan, who became known as "Air Jordan", changed basketball with his graceful moves and jumps. His skills were{#blank#}6{#/blank#} (impress), but the mental strength he showed made him unique. In the final seconds of a game, Jordan always seemed to find a way {#blank#}7{#/blank#} (win). Jordan says that the secret {#blank#}8{#/blank#} his success is learning from his failures. Losing games taught him to practise {#blank#}9{#/blank#} (hard) than before and never give up. In life, Jordan has learnt to share his success with others. The Boys and Girls Club he started in Chicago {#blank#}10{#/blank#} (help) young people since 1996.
