Do you play with your phone before bedtime?     1     According to a US study, looking at electronic screens (电子屏幕) at night can’t help us to sleep well. Now let me tell you how we get bad sleep.

In the evening, our bodies make melatonin (褪黑素).     2    . It’s an important part of our sleep. But our electronic screens stop that working as usual. Why? Phones, computers and TVs make blue light.     3     Even just a little blue light can have an effect (影响). Eight minutes of blue light can keep your brain (大脑) “awake” for an hour. Even if you sleep, you may have lots of dreams.

It’s worse if you play an exciting game before bedtime. Games make our hearts beat faster.     4     .Then even after we sleep, we don’t get enough “deep sleep”.

    5    . Don’t worry. First, do something relaxing every night—take a warm shower or read a book. Next, sleep in a dark, quiet room that is not too warm or too cold. Also, you can count sheep. It works! And don’t eat a big meal or have coffee. You’d better drink milk. Finally, don’t run or exercise three hours before bedtime.

①Winter is cold in some places. Many plants do not grow during winter. Some plants die. Snow and ice may cover the ground. It can be hard for animals to find food during winter. But animals get through this time in many ways.

②Birds and butterflies can fly. Many of them do not stick around for the winter. They leave. They go to a place with nice weather. Then they come back in the spring. We call this migration. Migrating is a good way to avoid（避免）the cold.

③Another good way to avoid the cold is to sleep through it. Many animals hide during the winter. Their bodies slow down. To save energy, they do not eat. They live off the fat in their bodies. They do this until they can get food again. We call this hibernation. Snakes, frogs, and bears hibernate.

④Some animals store food in their homes. They do not sleep all winter, but they do much less. They live on what they saved in the summer and fall. This is what squirrels and beavers do.

⑤Other animals tough it out（咬牙坚持）. They do not leave or hide. Sometimes nature helps them out. Some animals grow thicker coats in the winter. Other animals change color. The arctic foxes are brown in the summer. Their coats turn white in the winter.

⑥Winter may be pretty. It is nice to see snow on the trees. But it is dangerous too. People are also at risk. You can get frostbitten（冻伤）or worse. How do you beat the winter?

【推荐1】A mini-program on WeChat has changed people’s lives at West Lake, as they can now make appointments(预约) to sell recyclables—things that can be recycled.

For a long time, the problem of recyclable rubbish troubled restaurants and hotels around the lake. Lots of recyclables have low value and high recycling costs,so collectors don’t feel like recycling them door-to-door.

In order to solve the problem, the Management Committee of West Lake Scenic Area worked with a company to develop the Jingling Recycle mini-program. Now, people can make an appointment on WeChat, and the next day collectors will come to pick up recyclables. The mini-program helps people to deal with plastic bottles, foam packing cases(泡沫包装箱), cardboard (硬纸板), newspapers and other low-value recyclables. People are paid to sell them.

The local people speak highly of the mini-program. “No collectors came to my restaurant in the past. Thanks to the Jingling Recycle mini-program, it has changed. I can make a little money by selling recyclables. At the same time, it protects the environment,” said the owner of a restaurant.

【推荐2】Do you enjoy reading? Here readers of your age from all over the United States recommend (推荐) great books for you to read:

My favorite book is Don't Die, My Love by Lurlene McDaniel. I love all her books, but this was the first one I read and I have to say, it is by far my favorite. It doesn’t end like other books, and I cried while reading.

I think Nancy Drew is great! Nancy is a detective (侦探) who has many fantastic ideas! I love it because it’s a book from when my grandma was my age, and I can share the fun with her!

I highly recommend Skinny Bones by Barbara Park. It is funny, so please add it on your book list. You don’t want to miss out funny stories!

I would suggest Growing Trouble by Judy Blume. It is based on real things that happened to Judy Blume. It is about a girl, Alice, who meets some girls at a new state. They become friends, make a club and meet once a week. They stop after two weeks because they all like a boy in their class and put him as number one. I think every girl should read this because it is about our growing up.

I read a book called Neela: Victory Song and it was so good, I read it twice! It takes place in India in 1936 and this 12-year-old girl named Neela tries to save her father! It has lots of history in it! I also learned a lot about different cultures! The author’s name is Chitra Banerjee Divakaruni.

【推荐1】The COVID-19 (新冠肺炎) outbreak is changing people’s traditional habits such as greetings and customs. People in different countries have had some new and creative choices. Knowing about this could help us understand their cultures and communicate with each other.

France Newspapers have been filled with advice on how to change handshaking and kissing on the cheek. Now looking into a person’s eyes can satisfy that as a greeting.

Romania Martisor Festival marks the beginning of spring when the flowers and talismans (护身符) are handed out. But the government has told people to hand over the flowers and talismans without kissing.

China People are called on to greet each other through the Internet and not to get together if possible. They can join their hands together as a sign of greetings instead of shaking hands when they meet.

Iran A video has become popular. It shows that three friends are meeting. Two of them are wearing masks (口罩). Hands in their pockets, they tap their feet against each other as a greeting.

Australia People are not advised to shake hands. They can give each other a pat on the back. “I won’t say ‘Don’t kiss’, but you could be exercising a degree of care with whom you choose to kiss,” said an officer.

Thank you all so much for being here. It means so much to us. First, I'd like to thank everyone for coming today. The outpouring of love and support that my family has felt from around the world has been so uplifting. Thank you so much for all your prayers. I'd like to talk about both Kobe and Gigi, but I'll start with my baby girl first.

Gianna Bryant

My baby girl. Gianna Bryant is an amazingly sweet and gentle soul.

She was very thoughtful and always kissed me good night and kissed me good morning.

She loved to bake. She loved putting a smile on everyone' s face. Last August she made a beautiful birthday cake for her daddy, and it had fondant and looked like it had blue agate crystals. Kobe's birthday cake looked like it was professionally decorated. She made the best chocolate chip cookies.

Gigi was confident but not in an impolite way. At school she offered the boy's basketball coaches to help give the boys' basketball team some pointers, like the triangle offense. She was very much like her daddy and they both liked helping people learn new things and master them. They were great teachers.

Gigi was very sweet. She always made sure everybody was okay and she was our shepherd. She always kept our family together. She loved family traditions, and family movie night was important to her. She always looked out for everyone. She was very much in tune with our feelings and wanted the best for us.

Gianna knew how to read, speak and write Mandarin (普通话), she knew Spanish and had great grades and kept them up all while becoming a great basketball player.

Gigi would have most likely become the best player in the WNBA. She would have made a huge difference for women's basketball. Gigi was motivated to change the way everyone viewed women in sports.

She was a beautiful, kind, happy, silly, thoughtful and loving sister and daughter. She was so full of life and had so much more to offer this world. I cannot imagine life without her. Mommy, Natalia, Bianka, Capri and Daddy love you so much, Gigi. I will miss your sweet handmade cards, your sweet kisses, and your gorgeous smile. I miss you, all of you, every day. I love you.

【推荐3】Have you seen Avatar (《阿凡达》)? It’s a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images (图像) from the movie look as if they were coming straight towards you.

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

When we look at an object (物体), each eye sees it at a different angle (角度). Our eyes send the two images to our brain (大脑), and the brain puts them together. 3D technology uses two film projectors (投影机). One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy (头晕的) or have headaches. A famous eye doctor said if your eyes can’t focus (聚焦) on the same object at once, you will have trouble watching 3D movies.

Mike is my friend. He is not healthy. He doesn't like vegetables. He likes chicken and ice-cream. He doesn't like fruit. He likes hamburgers，but his sister Linda doesn't. She likes vegetables very much. She likes tomatoes and carrots. And she likes fruit，too. She likes apples，pears，straw-berries and bananas. She likes ice-cream，too. But she doesn't have it. And she likes rice，eggs and carrots for dinner. She doesn't like chicken.

【推荐2】Once upon a time, there was a businessman who owed(欠债) a lot of money to a noble(贵族). The noble said he would forget about the money if he could marry the businessman's daughter. The businessman didn't want his daughter to marry the noble, but he was too poor to pay back.

The noble said. "I have an idea, I will put a black stone and a white stone into an empty bag. Your daughter has to pick one from the bag. If she picks the black one, she will become my wife and you won't need to pay me back. If she picks the white one, she needn't marry me. When your daughter picks the white one, you needn't pay back, either." The businessman and his daughter agreed.

The noble went to pick two small stones. As he picks them up, the girl noticed him pick two black stones and put them into the bag. He then asked the girl to pick one. The girl put her hand into the bag and chose a stone. Without looking at it, she threw it into a river.

She said, "Oh, silly! I didn't see the color of the stone. But if you look at the other one, you will be able to tell which one I have picked."

【推荐3】Jupiter(土星) is the fifth planet from the sun and it is the largest one in the solar system. It is about 11 times bigger than the earth. Jupiter's strangest thing is its huge red spot. Pictures taken from space tell us that the red spot is probably a hurricane(飓风). It is so big that the earth would fit right in the middle of it. Sometimes the hurricane looks like a huge oven with orange-red waves (波浪). Some other time the color almost disappears.

On the earth, hurricanes move. We can watch them travel across water to land. Jupiter's red spot also moves. Scientists say it “walks”. It is carried along by air in Jupiter's atmosphere(大气层).

So far, Jupiter has been visited by four spacecrafts. All of them flew by Jupiter very quickly. On the next trip to Jupiter, a spacecraft will stay near the planet much longer. New information will be sent back to the earth. Soon scientists will know much more about this strange red spot in the atmosphere.
