Have youheard of e-waste (电子垃圾), which can be produced every day? How do you deal with yourcomputers, MP4 players or mobile phones when they're broken or you want a newone?

    Mostpeople just throw them away. With the development of electronic industry (电子产业), e-waste pollution has becomea serious problem. According to the United Nations, in 2014, people around theworld produced 41.8 million tons (吨) of e—waste and only recycled 6.5 million tons. The US was the biggestwaster, producing 7.1 million tons. China came second, with 6 million tons.

    It'simportant to pay attention to e-waste. It can be either valuable or harmful,depending on how we deal with it. E-waste is a valuable urban mine (城市矿藏). The value of the metals,like gold and silver in the waste around the world, is surprising. And themetals can be reused. But if people throw them away, the toxic chemicals (有毒化学物质) can get into the earth or air,affecting the environmentand people's health.

    Apple, forexample, now recycles people's used products in China when they are buying newones. The company will test and repair the used ones and sell them at lowerprices. To help reduce e-waste, we can buy longer-lasting electronic products.If you have unwanted electronics, find a new home for them. You can also takecomputers and phones to companies to see if they offer recycling programs.

    Dean felt his arms and legs were burning. With each breath, Dean wondered if he should be done, but as he touched the wall at the end of the pool he turned for another lap (圈). "I can do one more. This is for Kevin," Dean told himself. He was starting his seventh lap.

    Dean and the other members of his swim team were swimming to raise money for Dean's best friend, Kevin Hawking. Earlier in the year, Kevin fell ill. He needed expensive medical care that his family couldn't afford. After Kevin's friends learned what was happening, they started brainstorming ways to help. Several of Kevin's friends were on the swim team, which led to the idea of swimming.

    For a month, Dean and the other swim team members had asked for pledges (承诺) from anyone who would help: family members, friends, and neighbours. Most people pledged a dollar or two each lap. Dean's grandmother said she would offer $ 10 for each lap Dean swam!

    Finally, as Dean completed his tenth lap, he knew he was too tired to keep going. If I try another lap. I'll end up lying in the middle of the pool, waiting for someone to come and get me, he thought. Dean pulled himself up onto the edge of the pool and sat breathing quickly for a couple of minutes, quietly resting before he tried to stand.

    Dean's father came over and said, "Wow, Dean," shaking his head in amazement, "I am so proud of you. That's farther than anyone else has swum today, and I know it's farther than you've ever swum before."

    Dean stood up and slowly walked with his father back to the seats where the other swimmers sat next to Kevin. "Thank you," Kevin said.

    "It's no big deal. I know you'd do the same for me," Dean said.

Lin Wenqian is a girl student. When she was on a busy bus last month, she felt someone touching her. She was so afraid.

Zhou Bin, 12, is a boy. He likes to chat on the Internet. But once a stranger said lots of dirty things to him.Zhou was so surprised!

What can students do when this kind of thing happens? Here is some advice from some teachers and students:

Don't be afraid. Ask him or her to stop at once. If he or she doesn't listen, try to turn to others around you and call for help.

Keep calm. Be serious and keep a cool face. Say you don't like it and show you are angry.

If there is no one around, use clever ways. If you only shout or fight to make them angry, it could make things worse! They may take your life. Find excuses (借口) to run away. Say things like you are waiting for your parents or you want to go to the washroom.

It is a nice day. Kate is at home with her family. {#blank#}1{#/blank#} She likes to read books very much. 

Her friend Mary calls her, "{#blank#}2{#/blank#} I have something for you. "

Kate goes to Mary's house, Kate sees a red note(便条) on the door. It reads, " Come in, Kate. And go to the sofa. " On the sofa, Kate finds a book. {#blank#}3{#/blank#} It reads, " Go to my table. "

{#blank#}4{#/blank#} Next to it, there is a yellow note. It reads, " Go to my bedroom. "

Kate goes to Mary's bedroom. And what does she see? {#blank#}5{#/blank#}

" Happy birthday, Kate. " They say. 

Today, we are going to make a simple cake. Here are the materials (材料) and ways. Let's have a try!

Materials

□ 1 cup of white sugar

□ 1/2 cup of butter

□ 2 eggs

□ 2 spoons of vanilla extract (香草香精)

□ 1 and 1/2 cups of flour (面粉)

□ 1 and 3/4 spoons of baking powder (发酵粉)

□ 1/2 cup of milk

Ways

◆First, you should preheat (预热) your oven (烤箱). Then you should cover a pan (平底锅) with oil and flour.

◆You should mix up the sugar and butter in a medium bowl. Then you can add the eggs, one  at a time. Next, you can add the vanilla extract, flour and baking powder to it and mix well. Finally, you should add the milk. Then pour it into the prepared pan.

◆Bake for 30 to 40 minutes in the oven. If you want to make cupcakes, you can bake for 20 to 25 minutes.

Travelling is not always happy, at least for the buddies in the movie Green Book. The popular film won Best Picture at the 91st Academy Awards on Feb. 25. 

The movie was adapted from the true story of a road trip through the southern US in the early 1960s. In the film, the black pianist Don Shirley hires Italian- American Tony Vallelonga to drive him to performances, but they face problems because of Shirley's skin colour. These problems lead them to form a special friendship. 

"There's something so deeply right about this movie, so true to the time," wrote US film critic Mick LaSalle. The time LaSalle is talking about was between late 1870s and 1960s, a very different period in US history. Many parts of the country had Jim Crow Laws (《吉姆·克劳法》) , which allowed racial segregation (种族隔离) . These laws made life and travel ____ for African- Americans. They couldn't use certain hotels, restaurants, or even gas stations. They had to be indoors after sunset or they might be put into prison. Even black celebrities (名人) had to follow the laws. 

But in 1936, a black mail carrier named Victor H. Green had an idea. He made a list of friendly businesses in New York City. He published the list as a small book with a green cover. The Green Book helped African- Americans travel more safely. Then, in 1964, Jim Crow Lawswent away. The book went away, too. 

Today many US people still remember the time of Jim Crow. But they probably don't know about the Green Book. It's a forgotten part of the story. Thanks to this movie, maybe people can remember it again.
