Alice Lee is a high school student studying at a private school. She is doing some voluntary work at an after-school program to help students from poor families.

    On the first day of her work, she noticed that many kids were lining up for free sandwiches and fruits. She was surprised. One of the organizers explains that many of these students don't get enough to eat at home. So a school lunch or an after-meal might be the most food they would get all the day. She has also been told that some hungry kids can receive free lunches, but others are only allowed reduced-price meals, and those students' families have to pay for the part of their food.

    Lee was shocked, she decided to offer help to those who are suffering from hunger, "I want other kids to understand that if you see a problem, you don't have to wait to be an adult to fix it," says Lee. She and a group of friends are using their programme skill to create a new app called Food of Thought, which will allow parents, students, and even kind-hearted strangers to donate money to lunch accounts for students in a nearby school.

    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.

Most of us find that smartphones have made our lives better. Almost all of us{#blank#}1{#/blank#} our smartphones within arm's reach during waking hours, and most of us do so when we sleep. What will happen {#blank#}2{#/blank#} we live without the smartphones?

In 2022, My family moved into a small village house. There was no Wi- Fi. It was my first time to taste the joy of a life. We learned to make {#blank#}3{#/blank#} use of time. We also realized that days lacking of digital product(数码产品) made time slow down and{#blank#}4{#/blank#} the quality(质量) of our time together. We could find a quiet place to sleep, cook simple {#blank#}5{#/blank#} to eat and enjoy the countryside views. The smartphone is just a tool. Without it, the {#blank#}6{#/blank#} seemed to more relaxing.

Our family went to the Yellow Stone National Park last summer vacation. Our son, Tom, wanted to see bears there. And what an experience it was!

When we got there, we put up our tent and went to explore（探险）. As we returned, we heard our daughter Susie cry out. And then we saw a bear go into our camp. 

Tom wanted his father to chase（追赶）him away. 

His father said, "No. It's dangerous to chase a bear. And don't let him chase you."

Susie said, "What shall we do? Maybe we should climb a tree."

Tom said, "No. We have to get him out of there. He might go to sleep in our tent."

"Maybe we could make him leave if we put some honey outside for him to eat." Susie suggested. 

Then I said, "How are you going to get the honey? It's in the tent."

We watched the bear go into the tent and heard him upset（翻倒）everything inside. 

"It's foolish for us to try to chase him away." said my husband, "Leave him alone and wait for him to come out."

We waited, but the bear stayed inside. We had to sleep in the car that night.
