I used to think education was the most important thing in my life. Recently my attitude has begun to change, although I still hold that it is essential for everyone in the world today. As a top junior student in my college, I was asked to make a speech on how to learn English well. Standing in front of the audience and facing so many freshmen, I was trembling. I didn't remember any word that I had prepared. I ran out of the conference room without finishing my speech, leaving everyone puzzled. I cried that night in my room, feeling that I was a loser. Studying takes up so much of my time that I feel unable to really develop myself. I am just storing knowledge, yet I fail to communicate with others. I have received many awards in school, but they don't necessarily reflect anything about me. I don't know how to socialize. When I leave school I fear I will be of no use to society.

    I realize that everyone has his own way of living. I want to change my lifestyle. Of course I will keep studying. Yet I plan to look for a part-time job, which might turn out to be a good chance to get to know society. I still believe that working my hardest makes me happy. I will still stay on in college. But I will not allow it to shelter me from the real world.

    Years ago, I lived in a building in a large city. The next building was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.

    After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn't wash her window. It really looks terrible.”

    One bright morning I decided to clean my flat, including washing the window on the inside.Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!

    Then it dawned on me. I had been criticizing her dirty window, but all the time I was watching hers through my own dirty window.That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?

    Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world about me more clearly.

    Six people are talking about the newly-built garden on the roof of their building.

    Jasmine: I loved the idea when Wilber first told me about it. We had lots of meetings with our neighbors, trying to make them understand why it's good to build a garden on the roof. Now people love coming here, and we have made a lot of friends!

    Wilber: The whole thing wasn't easy at first. But Jasmine helped a lot. And she was really good at making people happy to donate (捐赠) money for the roof garden.

    David: My kids love going up there. They sit there watching butterflies and birds. The roof garden brings them closer to nature.

    Samuel: You want something green? Visit the park! It's only one block away! After the roof garden was built, small insects started flying into my room! And the kids leave mud on the stairs when they come down from the roof!

    Rosie: Our building is now cooler in the summer. My baby sleeps well even on hot summer days!

    Flora: Guess where these tomatoes are from! Not from the supermarket. They're from our roof! It's wonderful, isn't?

    When I was three years old, I couldn't speak. It was a strange reality that none of the doctors I visited could understand.

    One day, I was shadowing my mother. She found herself looking in a mirror, and through it our eyes met. She began to speak to me through the reflection, and I slowly began to mimic(模仿)her mouth's movements until I formed a word.

    It turned out I'm deaf in my left ear, and have a slight problem in my right. Being hard of hearing has been difficult, but I've never lived in a state of self-hating sorrow. Imagine being able to shut out all sound as you lay your head down to sleep by simply rolling over onto one side. That's my reality when I sleep on my "good ear", and it makes me feel like a superhero sometimes.

    People call my deaf side my "bad ear", but when I wear my hearing aid, I have access to a range of features that some other deaf people don't. In cinemas, for example, with one click of a button I can enjoy a whole film as though it were whispered to me from the mouths of the actors.

    Owning a hearing aid hasn't always felt good, however. On the first day I got my aid, when I was eight, I took it to school for show-and-tell. As I explained how it worked to my classmates, a boy yelled out, "Aren't those for old men?" At that moment, I felt different. It took a long time for me to get over that sense of being so unlike my peers.

    But it's not just school kids who can make us deaf and hard-of-hearing people feel like burdens. Every video on social media that lacks subtitles(字幕), for example, means an entire community of deaf people is unable to enjoy it. Completely deaf people are excluded from enjoying many movies too, as subtitles in cinemas are almost impossible to find.

    And with hearing aids costing around $2,500 each, it can be hard for many people to afford to be able to listen to the things that others take for granted. As for me, I can listen to music, enjoy films, and catch conversations - I'm lucky. I'm deaf, but I can still hear everything. I've been blessed with wonderful life experiences, and I am human. And when it comes to sleeping, I'm even superhuman.

    Body language is the quietest, secretest and mostpowerful language of all! It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying...

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't kit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased.

    Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust(厌恶)and fear to come through.

Nick Torrance, a junior in high school, suffers from muscular dystrophy, and attends school in a specialized wheelchair. The muscle disease prevents him from accomplishing many everyday tasks, such as carrying his books and putting things away in his locker. So he had a fellow student assigned to help him. But Amy Smith, the school's occupational therapist, thought that being able to do something simple like opening his locker on his own would be empowering.

Amy initially thought they would be able to buy a device to help. But searching online turned up nothing that could meet their needs—everything needed a keycode or some other physical action, things her disabled student couldn't do. After the outside search for a method came up short, she looked within the school itself for an answer. Amy turned to the school's robotics instructor.

The instructor, in turn, suggested that two of his most capable students take on the project: Micah Stuhldreher and Wyatt Smrcka. They took first place in a national robotics competition, so they were a natural choice to tackle the locker door problem with a robotics solution. Micah and Wyatt wasted no time getting down to work and for an hour each school day, the boys brainstormed, built, and rebuilt various versions of the device until they landed on the perfect solution one year later.

Like in any device development, it took a lot of trial and error for Micah and Wyatt to make something that would work for their target audience. For example, they initially built a locker-opening button, but Nick wasn't strong enough to push it, so they replaced it with a sensor.

Now, between classes Nick steers his electric wheelchair to his locker and waves his hand over a sensor on the arm of the wheelchair. A few seconds later, the locker door swings open. Another wave closes the door. Nick can make it with ease—it may be a small thing, but it gives him a sense of independence.
