Ellie was a skilled gymnast (体操运动员). But she liked showing off (炫耀). At the gymnastics tryout (选拔赛), she put on a perfect performance." See who can do that!" she said proudly.
The next Friday, the list was posted announcing who had made the team. Ellie's name wasn't on it." It's unfair. I'm better than all the other girls!" she said. She went to see the coach.
"You are quite talented, but your attitude is terrible," the coach said." Making the gymnastics team isn't just about gymnastics. It's also about being on a team." That night Ellie complained to her parents. Her mother was angry, but her father said that the coach had a point. They had a big argument. Ellie couldn't sleep. She kept thinking about what the coach had said.
Ellie couldn't stay away from the gym, so she practiced alone. One day, after watching Ann fall off the parallel bars (双杠) again and again, Ellie ran to her and explained to Ann what she was doing wrong. Ann did as Ellie suggested and improved. Ellie didn't notice the coach was looking at her. Over the next few months, Ellie always helped the other girls. They did better and better." We couldn't have done this without Ellie's help," the girls said.
The following year, Ellie tried out for the gymnastics team again. This time, she was modest. When the girls praised her, she just smiled and thanked them. When the coach posted the list of who had made the team, her name was on it. Ellie and the other girls were all very happy.
①Ellie practiced alone. ②Ellie's parents argued.
③Ellie coached other girls. ④Ellie showed off at the gymnastics tryout.
Teenagers who start the school day really early are likely to weigh slightly more than those who start later. That's the finding of a new study of nearly 30,000 Canadians between the ages of 10 and 18.
Getting too little sleep can put kids at risk for a number of problems. Sleepy teens are more likely to be overweight, to have trouble concentrating and to struggle in school. Geneviève Gariépy, who works at McGil University in Montreal, Canada, wanted to know how earlier school start times might be connected with weight." Overweight in teenagers is a big problem in North America," she says. The number of overweight kids has grown over the past 30 years. About one in three American and Canadian teens are now overweight. Kids who don't sleep enough may be at higher risk. So Gariépy decided to home in on the effect of school start times. Her team collected start times for 362 Canadian schools. Then they asked students at those schools to give their height and weight. In all, they collected data from nearly 30,000 10-to 18-year-olds. Among 6th-to 10th-graders, those who started school earlier were likely to be slightly heavier for their height. Every 10-minute delay (延迟) in school start time was connected, on average, with a slightly lower weight among students who were the same sex (性别), age and height. However, the difference is slight. Healthy eating and getting enough exercise will play a bigger role in keeping a healthy weight.
Because the study compared kids who already started school at different times of day, it's not clear that changing school start time would help heavier kids lose weight. To know for sure, researchers would want to compare the same kids before and after changing to a later school start time.
Still, the study is a good start, says Cora Collette Bruener, a doctor at Seattle Children's Hospital in Washington. The findings add to a growing pile (累) of evidence that later school start times might be better for teen health, she says.
There are many ways for diseases to spread. A sick person can cough or sneeze on someone nearby, or they can spread germs (病菌) through a handshake. But sometimes we pick up germs indirectly. A sick person might leave behind bacteria or viruses when they touch a door handle, for example. But what if those surfaces could clean themselves?
Two teenagers from Hong Kong asked themselves the same question. Now they've developed a door handle that can kill germs on contact (接触).
The idea is simple. Every time the door is opened, the movement creates power that starts a germ-killing reaction on the handle. In lab tests, their system killed about 99.8 percent of the germs that they spread onto lab dishes covered with their material.
Research by others has shown that door handles in public areas are often home to lots of bacteria and viruses, notes 17-year-old Sum Ming ("Simon") Wong. He and his schoolmate Kin Pong (Michael) Li, 18, wanted to design a covering for door handles that would kill germs.
After doing some research, they learned that a mineral called titanium dioxide (二氧化钛) is known to kill bacteria. It's already used in many products, from paints to desserts. To make their covering, the teenagers made the mineral into a very fine powder.
Titanium dioxide kills bacteria best when lit by ultraviolet (紫外线的) light, says Simon. UV light is found in sunlight. But UV light does not naturally shine on indoor handles or any used at night, so the teenagers light their door handle from within.
To make sure the light reaches the coated surface, the teenagers made their door handle out of clear glass. Each end fits into a bracket (托架). Inside one of the brackets is a strong light-emitting diode (LED). From it comes UV light.
And here's the interesting part: The power that makes the UV light shine comes from opening and closing the door. The power from the door is then carried by wire to the LED inside the door handle.
The door handle system, Michael and Simon say, might cost no more than about $13 (about 81 yuan) to build.
We all know that early birds get more things done by making the most out of their mornings and setting the day right for successful completion of all goals and tasks. Successful people not only have healthy morning habits, they also know how to finish off their day right. Here are some habits that can help plan a more productive tomorrow:
1. Read a book. Successful people read daily. By reading daily, they can achieve better results in their professional and personal lives. Reading will not only make you more likely to succeed, but if you do it before going to bed, it can really help you to reduce stress and progressively calm you down.
2. Unplug (远离) from social media. At the end of each working day, the most important thing is to switch off distractions such as WeChat, emails and messaging to create some time for yourself.
Go to bed earlier, take a bath, go to that cooking class you have been putting off for so long, or spend quality time with the person you love.
3. Organize the following day. It is really difficult to remember all the things you need to do, so why not write them all down in a journal or a to-do list? Successful people know the importance of a well-planned day and this allows them to enjoy themselves in the evening. So before you go to bed, grab a planner or a notebook and write down your 3 most important goals for tomorrow.

Today our class paid a visit a farm. Early in the morning, we met at the school gate and went there together by bus. The farm workers give us a warm welcome at the farm entrance, what moved us deeply. Then we were showing around the wonderful agricultural garden.
How happily we were to see the crops and vegetables growing well. At noon we sat and had a picnic lunch in the sunshine, sharing snacks, fruit and drinks. After a ten-minute break, we had a great fun telling jokes and story, as well as singing and dancing. Two of them even played a game of chess.
Time went by quickly. After we knew it, it was already dark because we had to leave.
