We live in a society that is producing and using electronics（电子产品）all the time. What happens (A) ____your computers, MP3 players and cell phones when they're broken or you want a new one?

Most people just throw them away. In 2014, people around the world produced 41.8 million tons of electronic waste and only recycled 6.5 million tons, according to the United Nations last month.

It's important to pay (B)           to e-waste. It can be either valuable or harmful, depending on how we treat it. If people throw it away, the toxic（有毒的）chemicals can get into the soil or air, affecting the environment and people's health.

To help reduce e-waste, the first thing we can do is to buy longer lasting electronic equipment. If you have unwanted electronics such as old toys or cell phones, find a new home for (C) them by giving them to charities. At the same time, (D) you can take computers and phones to the producers to see if they offer recycling programs. Apple, for instance, now offers people a discount（折扣）in China if they hand in their used electronics when buying new ones. The company will test and repair the used ones and sell them at lower prices.

    If you have no special plans for your holidays, why not spend your time helping others?

    Don't listen to people who say the young people today often think only of themselves. It's not true at all. More and more young people in the U.S.A. volunteer to spend their school holidays working for others. And they don't do it for money. Here are some of their stories.

Information Card

    "How are you?" is a nice question. It's a friendly greeting that people in the United States use. {#blank#}1{#/blank#} It's a question that often doesn't need an answer. The person who asks, "How are you?" expects to hear the answer "Fine," even if the person isn't fine. The reason is that "How are you?" isn't really a question and "Fine" isn't really an answer. They are common ways of saying "hello" or "hi".

    {#blank#}2{#/blank#} For example, when someone asks "Do you agree?", the other person may be thinking, "No, I don't. I think you're wrong." It isn't polite to disagree very strongly, so he might say, "I am not so sure." {#blank#}3{#/blank#}

People also don't say exactly what they are thinking when they finish talking to other people. For example, many conversations over the phone end when one person says, "I've got to go now," or the person who wants to hang up gives an excuse such as "Someone is at the door," or, "Something is burning on the stove." {#blank#}4{#/blank#} The person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say so. An excuse is polite, and it doesn't hurt the other person's feelings.

    Whether they are greeting each other, talking about an opinion, or ending a conversation, people often don't say exactly what they are thinking. {#blank#}5{#/blank#}

A. This is a nicer way to say that you don't agree with someone.

B. You'd better not to tell the truth to your family.

C. However, "How are you?" is also an unusual question.

D. The excuse may be real, or not.

E. Sometimes, people don't say exactly what they mean.

F. If you disagree with others, they will hate you.

G. This is one way of being nice to people, and it's a part of the game of language.

    In 30 years from now, what will we eat? Will the food still be the same as it is now?

The United Nations says that there will be over 9 billion people in the world by 2050. Our food needs will grow by 70%. What we eat now may not be enough for humans in the future. That is to say, we'll have to turn to something else. But what else can we eat? Here are a few possible choices.

    Veggie (Vegetable) meat

    A new kind of hamburger is now popular in the US. It looks the same as any other hamburger, and so is the taste. But it's actually a "beef" burger made out of plants. The company behind the burger, Impossible Foods, uses peas and potatoes to make the "beef". They take coloring, protein (蛋白质) and fats from these plants and mix them together.

    Making meat out of plants uses less water and land than raising animals for meat. It also creates fewer green house gases. Some food companies are making chicken, pork and other meat out of plants, too-follow the same steps as making the "beef".

    Insects

    Insects take up little space and don't make much waste. They also have more protein than beef, chicken and pork. This makes insects another possible food of the future.

    It's common for people in some places to eat whole insects. But most people probably won't want to see the insects they eat. So in the future, people will first turn insects used for food into powder (粉末). Then they can use the powder to make other foods like chips, protein bars, biscuits and so on.

    Algae

    The BBC says algae farming could become the world's biggest farming industry in the future. They point out that algae is cheap and grows very quickly. Also, it's very nutritious (有营养的). It has much more protein and oil than many other plants.

    Besides eating algae as a dish on its own, people may also use algae oil and algae butter in the future. Some algae has a strong taste. The UK scientists are trying to use algae to take the place of salt.

    Last year, I did not like my English class. ⑴Every class was like a bad dream. The teacher spoke so quickly that I did not understand her most of the time. ⑵I was afraid to ask questions, because my pronunciation was poor. I just hid behind my textbook and never said anything.

    Then one day I watched an English movie called Toy Story. ⑶我爱上了这部激动人心又有趣的电影。So I began to watch other English movies. I discovered that listening to interesting conversations is the secret to language learning. I also learned useful sentences like "It's a piece of cake" and "It serves you right". ⑷I didn't understand these sentences at first. Then I looked them up in a dictionary. ⑸现在我非常喜欢我的英语课。

    Connor Bloom had an amazing two weeks at Stanford University this summer. Eyery part of the experience was amazing. The particle accelerator(粒子加运器), the chance to meet like minded kids from across the world? You guessed it. . .

    Bloom, 14, an eighth-grader at Whitefish Middle School in Montana, US, participated in a special camp at Stanford University. The camp holds many different classes for students who want to challenge(挑战)themselves.

    When Bloom looked online and saw that Stanford was to hold the "Gified Youth" program, he signed up(报名). "I like physics and math. 1like to study new things and find out everything about them, "said Bloom. " That's what made me want to sign up. "

    He handed in his test scores from fifth grade on, wrote an article and got recommendation(推荐)letters from teachers. Bloom stood out among thousands of students and got the invitation.

    Bloom had a great time with 86 students from all over the world. On the first day, they learned college-level math. Over the next four days they got to work in laboratories(实验室). They even touched a dead body to learn about how the human body works.

    In the second week, they saw the school's particle accelerator, "I never saw such a machine before, "said Bloom. " But it was just the mental workout(智力测验)1 was hoping for. "

    Bloom did more than just study for two weeks. He made friends with students from China, India and Japan. He worked together with other students in class to learn better. He spent his free time with kids who were also music fans.

    "Once we got to know each other, we helped each other out, "he said. " We learned a lot from each other. that's for sure. "
