Most teens need more than 9 hours of sleep each night. But about 1 in 4 teens has trouble in sleeping. Lack of sleep can affect everything from our feelings to how well we focus on tasks like studying. It can also influence sports performance, increase our chances of getting sick, and may lead to weight gain in some people.

    How can we get the sleep we need? Here are some ideas:

    Be active during the day. Get at least 60 minutes of exercise a day. Physical activity can decrease stress and help people feel more relaxed. Just don't work too close to bedtime because exercise can wake you up before it slows you down.

    Say goodnight to electronics. Experts suggest using the bedroom for sleep only. At least shut everything down an hour or more before lights out.

    Keep a sleep routine. Going to bed at the same time every night helps the body expect sleep. Creating a bedtime routine can improve this relaxation effect. Reading, listening to music, spending time with a pet, writing a diary or doing anything else can relax you.

    Expect a good night's sleep. Instead of worrying that you won't sleep, remind yourself that you can. Say "Tonight, I will sleep well." several times during the day. It can also help to practise breathing exercises or gentle exercises before bed.

    Everyone has a sleepless night once in a while. But if you regularly have trouble in sleeping and you think it's affecting your mood or performance, talk to your doctor.

Children all around the world love Lego bricks(乐高积木). With those bricks, they can make anything they want. Lego bricks are a great toy(玩具) to play with. Now, for the first time, Lego makes Braille Bricks in English and French, making them a useful toy for blind(失明的) children. 

Lego Braille Bricks have dots (小圆点) on them. The dots are Braille. By feeling (感受) them, blind children can read words and numbers. They can also learn Braille when playing with the bricks. It makes learning easy and fun. 

Olivia is a blind girl, and she learns Braille when playing with the Lego bricks at her school. She loves to play with them and learn Braille at the same time. Her mother also plays with her at home and now she also knows Braille. 

Reece, a little boy, uses the Lego bricks to teach his family Braille. Now, his mother and sister know Braille as well. He says, "I feel so good. Because my loved ones learn something new and I am their teacher. So cool!"

Lego makes its colourful bricks useful. Let's thank it for bringing a new way of playing and learning!

Mother's Day first began in America. A mother was very kind. After she died, her daughter wanted to remember her so she wanted to make a day for all the mothers. In 1913, America decided to make the second Sunday of May to be Mother's Day and every family had to put up a national flag to show their love to mothers. Later, it became an important festival to remember and praise(赞扬) all the mothers in the world.

In China, some people want to make our own Mother's Day. There is a famous story about Mother Meng. She loved her son very much and did a lot for her son. Chinese people think she was a great mother, so people want to make lunar(阴历的) April 2nd to be the day. Because Mother Meng's son——Mengzi was born on that day.

On Mother's Day, children often help their mothers do some cleaning and they also buy gifts for their mothers. Some mothers even go for a trip and have some other activities to celebrate this day.
