One day a professor entered the classroom and told the students about a surprise test. Now the professor gave the test papers to all students with text facing down at the desk. After he 1 the test to all students, he asked —them to turn the test pages and begin.

    Students were 2 to see that there was not a question but just a black dot(小圆点）in the center of the page. The professor 3 the students' face expressions and told them," I want you to write about what you see there."

    The students were 4 surprised but got started with the test. At the end of the class, the professor took all answer papers and started reading each 5 from each paper. All of them 6 about the black dot and tried to explain its position(位置). After the professor finished reading, the whole class was 7 .

    8 , the professor explained, "Don't worry. I'm not going to give you 9 for this test, but I just want you to think about something. Here everyone paid attention to the black dot and wrote about it 10 no one wrote about the white paper, the same is with our lives. The white paper represents our whole life and the black spot represents 11 in our life.

    Our life is a gift given to us 12 God, with love and care, and we always have reasons to celebrate-our friends around us, the joy 13 provides us our livelihood, the happiness in our families. Still we only care about problems like health problems, study problems, problems in relationships, but we 14 see that these problems are very small compared everything we have in our lives”

    So we should try to take eyes off our problems and enjoy each nice moment that life gives 15. Just smile, and life will smile to us!

    Artificial intelligence (AI) means the ability of a computer or a robot to do "smart" things. Al products all make our life easy and fun. During the past year, Al has done more amazing things. Let's find out!

    Research suggests that at least 64% of people now spend up to four hours daily of spare time in front of a screen. Just as a TV watching has been linked to higher chances of being fat and getting all kinds of diseases, this extra sedentary time is bad news for our health.

    Choose outdoor activities over technology

    When you're at home, make it a rule that you can't be online if the sun is shining. Instead, you have to go for a walk, swim or get some other kind of healthy physical activity for at least an hour before you can pull out your phone or take a seat at the computer. This rule should be fit for everyone in your family.

    Limit social media use

    Social networks have changed computer and mobile use for people of all ages. Whether it's a Facebook or Twitter, limit the amount of time you spend on social media. Avoid aimless browsing and give your time online a purpose: Research holidays or catch up on the news of the day. Then log off.

    Save time for reading

    Challenge yourself to read at least 30 pages of a great book before you check your computer or mobile phone. Pick the right reading material and you'll soon find you've discovered an enjoyable pastime.

    Create projects for yourself

    It's amazing how much you can achieve when you're not glued to a screen. Do a list of one-hour evening projects. Some suggestions are organizing kitchen cupboards, cleaning your bedroom. Then try to do one each evening.

    Mandy Harvey is a 29-year-old singer from Florida. She lost most of her ability to hear when she was 18.

    Harvey became a singer in her teens. _________ But she decided to start singing after she learned how to feel a song's beat through the wooden floor of a stage or theater. She watches carefully to make sure her musical instruments are tuned correctly and she is singing in the correct pitch.

    Harvey is now a professional singer. But not many people in the United States had heard of her until Tuesday night. That changed when she appeared on the television show “America's Got Talent”The show has four judges who watch people perform and decide if they should continue in the competition.

    Harvey said, "I gave up singing after I lost my hearing. But I want to do more with my life than just give up." As she was singing, one camera cut away to capture images of people in the theater. Many were seen crying. At one point, everyone stood up and cheered. By Wednesday afternoon, a video of Harvey's performance had been played 46 million times.

    Why? Shortly after she finished singing, Simon Cowell, one of the judges, gave her a golden star into the air. That meant Harvey could move on to the final round of the talent competition. Cowell said," I've done this a long time, and that was one of the most amazing things I've ever seen and heard."

    Many people wrote online that Harvey's performance was encouraging, and they will not give up on anything they want to do, either.

    Andrew Holleman, a 12-year-old boy, loved playing in the open land near his home. The land was wet and forested, and made a home for birds, other animals and many different plants.

    It made the perfect place for him to study and get to know nature. He had seen some red-tail hawks, red foxes, wood turtles and other animals. He also found special native flowers.

    Suddenly it was reported that the "empty" land would be improved by a lot of houses on it. The plants would be removed, the animals would run away and most would probably die. Then the wet soil would be covered with extra grounds.

    When he heard about the news, he was not happy. He was very worried that the land and water would be polluted. Andrew wrote down clearly all the research he had done about the area, and how the houses would affect(影响)the local environment. He sent letters to members of local government and television reporters. He also called on his neighbors to oppose the building of the houses.

    Although he was only 12 years old, he had the courage and wisdom of a person much older.

    Andrew's teachers described him as a gentle, shy and active. His classmates also admired how much he knew about local animals and plants, and the environment. Each day after school, Andrew went door-to-door, to ask the people to sign(签字), who did not want the houses to be built. In only one month, he got the signatures of 250 people.

    In the end, the land remained a safe place for birds, animals and plants that belonged there.

    Andrew won many prizes for his brave and great work to stop the houses being built, and he helped save the environment.

    Started in the year 1970, Earth Day is now celebrated in more than 193countries each year. Every year, the event is celebrated under a different theme. The theme for 2016 is" "Trees for the Earth". Here are five things you can do to celebrate Earth Day (apart from planting trees)and make this a better world for future generations.

          .

    Cars, being the greatest source of air pollution, can be left at home this weekend. Traveling by public transport is the better choice. Other greener choices are carpooling, riding a bike or you can also walk if your workplace isn't that far away from your home.

          .

    NO, we don't mean you should be dirty. We simply mean to say, don't take a bath every day. A day or two without a bath won't harm you, but it will certainly do a lot of good for our planet. Water saved is the planet saved.

          .

    This is one of the best things you can do. Why? Because it will do you good, too. Volunteer to join other tasks. If you have time, you can plant trees, clean a park or simply come up with ways you can preserve mother Earth.

          .

    This is one of the most common things that people can do at home, that is, turn off their lights. However, this isn't something you should do just for a day. Save energy by turning off all electricity points whenever they are not in use.

          .

    Do something every day that will improve your surroundings and contribute to making the planet a better place to live in. Always remember that every step counts.

    What will happen if a family is without the Internet for a month? One        (美国)family decides to find out. They have sent invitation to a leading US television station, expecting that it will send a film group to        (记录)their day-to-day life without technology for a month.

    When the film group meet the Smiths, they find that Mr. Smith, Mrs. Smith and their two sons are so crazy about technology that they        (几乎不)do things together. At mealtimes, no one sits at the dining table for their food. "Everyone just runs into the        (厨房), takes their food and then goes back to their screen," Mrs. Smith        (解释). “If we always do like this, our family will become strangers to each other!”

    Getting back to the        (正常的)life without the Internet is not easy, especially when the Smiths lose       (他们自己)in it. They have to make many        (改变). For example, the two brothers have to go to the school library to borrow books for their scientific projects, and Mr. and Mrs. Smith need to go out shopping. As the family have picked up the new lifestyle, they find that they can spend more time talking over meals, playing sports and doing all kinds of       (活动)together. Naturally, their life is better than before.

    Sitting at a desk in a classroom all day can be pretty boring. With a bike, the reading class can be        (interesting) than before.

    The teachers in        school in the USA have tried this. The Read and Ride program       (begin) five years ago. As part of the Read and Ride program, the teachers change the students'       (desk) into exercise bikes. With this program, one classroom in the school has enough bikes for each student in class.        is possible for the students to ride bikes and read books at the same time. Even common classrooms have one bike at the back of them. The students who cannot sit still can use the bike        (do) exercise. The exercise bikes are not only good for the students' health but helpful in        (improve) the efficiency of the students' study. When students are bored with study, they can relax themselves        riding the bikes for a while.

    After keeping trying the program for one year, the teachers found that the students        took part in the program did much better in reading tests.        amazing it is!
