Adam and his parents buy things in different ways. Adam likes shopping on the Internet on weekends. http: /club. 360 buy. com is his favourite website(网站). He often buys things such as mobile phones(手机)and cameras(照相机)on it He spends about two hundred yuan buying things on it each month. It often takes him three days to get his products.

    But Adam's parents never shop on the Internet. They can't see the real products (产品)and they often worry. Adam's mother likes buying clothes but she can't try them on(试穿) if she buys the clothes on the Internet. So she often goes shopping with her husband(丈夫).

    It was very cold, Amaya was warm in her house, thinking about an article she'd read at school. The article was about kids who 1 out their communities, and she thought it would be really cool to help her own town, Harvard.

    The only2 was that she wasn't sure how to help. In the article, the kids had grown food for people who needed food, but it was winter. She couldn't start a garden. Amaya was deep in thought when her mom said it was time to go shopping.

    As they drove along the road, Amaya saw a family wearing only light jackets. The cold wind blew 3 outside. How cold they must be! That gave her an idea! She could 4  winter coats, hats and gloves for people who needed them.

    She shared her idea with her mom, who thought it was great. But how would they 5 the idea to get plenty of winter clothing? Amaya decided to talk to her teacher, because then she could share her idea with her classmates at least.

    Ms. Monroe agreed when Amaya talked about her idea. They decided to call the 6  Hats in Harvard. Then they wrote a letter explaining the project. They also met with the headmaster during lunch time. He was excited about the idea, and said he would make sure copies (复印件) of the letter went home with all the students.

    They collected enough winter clothing in only one week. Then they left the clothes around two parks, so families who needed clothes could get them there. Three days later, Amaya and her mom went shopping again. She saw the same family that had given her the7for Hats in Harvard.  This time, though, the family wore some new coats, hats and gloves. Amaya felt 8 in her heart, and was very glad she could help others.

Zhou Dao's grandfather has a hearing problem. During a family party last year, Zhou Dao noticed something. His grandfather sat quietly by himself. The old man was unable to join the talks.

Zhou Dao was sad about this. "Grandpa always reads subtitles (字幕) to watch TV," he thought. "Why can't we put words on our talks?" Then, Zhou Dao began working on that idea. He spent about half a year developing a kind of smart glasses. These smart glasses help users "read" spoken words.

The glasses are connected to a smartphone. There is a microphone on the glasses. It records audio (录制音频) and sends it to the phone. A piece of software turns the audio into words. People can see the words on the glasses.

This allows users with hearing problems to understand others during the talks well. Now Zhou Dao's grandfather can wear the glasses and speak to someone else face to face or over the phone.

Zhou Dao was happy to help his grandfather. Slowly, more and more people in need can wear this kind of glasses.
