When I had something difficult to do, I used to ask my mom for help. But she always said, "Do it yourself, my dear." I would get so angry. I thought she was the laziest mother in the world!
For example, one day, I decided to invite some friends to my home. My bedroom was in a mess. Books, clothes and shoes were all over the table and ground. I didn't make my bed, either. I asked, "Could you please help me clean the room, Mom?" But she said seriously, "Do it yourself, my dear girl. I'm busy. You should do it yourself. "
Because of my "lazy mom", I have to do many chores, such as washing my clothes and cleaning my room. I have to help my parents and my little sister. And I also have to go to the dentist by myself.
It is really hard for me to do everything on my own, but I have learned a lot. As time goes by, I understand my mother. Thanks to her "laziness", I become clever and hard-working. Just as my mom always says, "A lady can't be lazy, or she'll be crazy. Work can make you sunny!" What a great mother! Don't you think so?
Can one paper bag change the world? Sarah Murphy believes it can and she tries to do something about it.
The seventh grader from the United States, decorates (装饰) lunch bags for the homeless.
She wants to bring hope to those people. She fills each bag with a lunch and gives them away to homeless people in the town, through a charity program.
Sarah Murphy has a great interest in charity. She used to donate money to charities at her school. Then she heard about the charity program from her friends. So she wanted to do something special, too.
To attract the help of more children, she reached out to a local library and made a program. They set up a coloring station in the library. Children may take a bag, draw and write a message of hope. They can leave it on the front desk. They can also take it home and return it after coloring.

Malaria (疟疾) has been a big problem for humans since ancient times. Usually, people get malaria when infected mosquitoes (被感染的蚊子) bite them. Many people have died from the disease. Luckily, Chinese scientist Tu Youyou found an effective drug (药) called qinghaosu (青蒿素).
In 1969, Tu became the director of a national project to develop the medicine to treat malaria. They studied books about classical Chinese medicine. After reading more than 2,000 old remedies (药方), Tu and her team collected over 600 plants and listed almost 380 possible remedies for malaria.
One remedy, which is 1,600 years old, uses sweet wormwood (青蒿) as a treatment. Tu found it worked and tried to extract (提取) the qinghaosu from it to make a drug. The extraction failed at first, so Tu returned to the classical books again and finally found a way.
She used a low-temperature method to extract the qinghaosu and finally succeeded in 1972. After her team showed that qinghaosu could treat malaria in mice and monkeys, Tu and two of her coworkers decided to test the drug on themselves before trying it on human patients. It turned out that qinghaosu was safe, and all patients in the test got better. Gradually, qinghaosu became the first-line treatment for malaria recommended (推荐) by the World Health Organization (WHO), saving millions of lives around the world.
In 2015, when Tu was given the Nobel Prize in physiology or medicine, she refused to take all of the praise. Instead, she praised her coworkers and Chinese traditional medicine. She once said, "Every scientist dreams of doing something that can help the world."
Flying is a fast way to travel. But it is a big headache for some people. They can't help worrying about things like "Is turbulence (颠簸) a bad thing?" or "Is it dangerous if we don't change our mobile phones to flight mode (飞行模式)？" British newspaper Daily Mail spoke to some experts to answer these questions. They also tell us other interesting things about flying.
Turbulence is caused when two groups of air hit one another at different speeds. Wind, thunderstorms and being close to mountains can be reasons for this.
It's scary and uncomfortable. But it is not something you really need to worry about. "Even in extremely rough air (扰动气流)，the wings are not going to break off," said Patrick Smith, a pilot.
As the airplane flies higher and higher, the outside atmospheric pressure (气压) gets lower and lower. During the flight, the pressure inside the plane becomes greater than the pressure outside. When this happens, square windows can break. That's because having different pressures inside and outside puts' pressure on the corners of square windows. But rounded comers can spread the pressure through the window.
When passengers go to the toilet on a plane at an altitude (海拔) of 30,000 feet, there must be a question on your mind: Is their waste going to land on a farmer's house or a city street? Take it easy. The waste will land with the plane and the ground crew (地勤) will deal with it.
Some passengers believe mobile phones need to be turned off because they could bring the plane down. However, this is not true. If you don't change your phone to flight mode, pilots may hear unpleasant sounds in their headphones. It also influences radio communications. So it's still best to put it on flight mode.
