When was Bristol Zoo probably opened?A. In 1826.B.In 1766.C. In 1936.D.In 1836.BI must have looked deep in thought, or as deep in thought as an 11-year-old man can, when my grandmother glanced up from her weeding to ask,"You have something on your mind, don't you?"＂Yes,I was thinking that someday I want to be an Olympic speed skating champion like my hero, Eric Heiden. I want to be a doctor like my parents and I want to help children in Africa."I immediately knew I had confided(倾诉） to the right person when a knowing smile broke across her face. "Johann, of course! You can do anything you want to do!" she said simply. And with my grandmother's support,I set out to pursue my passions.14 years later, I was well ready to take hold of my first dream: becoming an Olympic champion. The Olympics in 1994 were in my home country,Norway. As I entered the Olympic stadium,I wasn't the best athlete,and many had doubts about my ability to perform well. But I had something special working for me. I had a woman in the first row who believed in me following my passions just as much as I did. For the first time ever, my grandmother was going to see me skate.It happened. Breaking a world record,I won the gold.As I stood on the podium(领奖台） that I had dreamed about my entire life, a curious question popped into (突然进入）my head. Why me? Why did I win, given all the other incredible competitors out there? The reason had to be more than a grandmother who shared a belief in her grandson's dream. The question led me to only one answer: because I wanted to make a difference in the world, and with all the media attention on my success,I could.I immediately knew what that difference had to be: hope in the lives of the children in Africa. Six months earlier,I'd been invited to Eritrea as an ambassador for Olympic Aid.24.What did the author's grandmother do when the author spoke out what was on his mind?A. She laughed at him.B.She supported him.C.She had no confidence in him.D.She felt quite surprised.25.How old was the author when he probably realized his first dream?A.At 20.B.At 22.C.At 25.D.At 28.26. What will the author probably tell us in the part following the passage?A. His efforts in helping the African children.B.His hard training in preparing for the next Olympics.C.His successes at other Olympic games.D.His grandmother's attitude towards him.27.What is the whole passage mainly about?A. It's mainly about a young boy who had many dreams.B.It's mainly about the encouragement from a grandmother.C.If's mainly about a sportsman who realized his first dream of helping African children.D.It's mainly about an Olympic hero who made a difference in the world.CMy challenge for you is this: to read a book for 15 minutes every single day for a month.Let me explain a bit,by telling you where the challenge came from. I have many things in common with my dad, like music taste and sense of humor,but sadly reading isn't one of them.I can happily spend a whole day with a book,but my dad can't read a book for longer than about 5 minutes. He reads emails , websites and papers for work, but not books. He's busy, so I think sitting down to read for just 15 minutes a day is a good way to relax and to introduce him to reading.My dad is not the only person who avoids books. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests , but I think there are lots of benefits of reading,which screen-based activities don't have.Firstly, it's better for your eyes. Looking at screens can be very stressful for your eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night's sleep.One reason why I personally love reading is that I'm being transported to another world- I would often forget the time or things around me! Reading is a great way to switch off before you go to bed,because you think more about the world of the book, rather than the real world, so you can truly relax. I know you can be transported to a different world in a film or a TV show, but I think books do it better.I also enjoy hearing what people are doing and finding out what they think. Reading gives me the chance to get to know hundreds of new people! It also teaches you to see things from other people's point of view,and understand other people's decisions or opinions. With a book, you can hear everything a character is thinking or feeling - you really can be inside someone else 's head!So give it a go! Take 15 minutes when you are waking up, going to bed,eating lunch, or having a coffee, If you read a lot, why not try 15 minutes of an English book, or pass the challenge on to someone else? Good luck, and happy reading!28. What does the author intend to do by mentioning his father in the text?A. He wants to show that his father is busy.B. He wants to show that reading is important.C. He wants to show that his father likes reading.D.He wants to show that many people have no habit of reading.29. What does the author mainly base on when he writes the text?A. His personal experience.B. Some scientific experiments.C. His father's personal advice.D.Knowledge from books.30. What does the underlined word "it" in Paragraph 5 refer to?A. Helping readers sleep well.B. Making readers feel relaxed.C.Transporting readers to a different world.D. Reminding readers of the real world.31. What is the author's attitude to reading?A. Negative.B. Uncertain.C.Supportive.D. Doubtful.DChina's lasting research and development efforts have helped the nation keep its pioneering role in developing 5G mobile communication technology, related standards and the licensing stage.Chinese telecom companies are trying to keep their leading role in the global race for 5G commercialization(商业化）．They are speeding up R&D of the fifth-generation mobile communication technology. The 5G technology is said to be at least 10 times faster than 4G services which means it will enable superfast downloads of ＂heavy" files like movies, self-driving cars and virtual(虚拟的）reality games. It will dolarge-scale experiments of using 5G in 17 cities. Yang Jie, chairman of China Telecom, said, " We aim to begin commercial 5G services in 2020."China Mobile Communications Corp is planning to use 5G with AI and cloud technology for a latest network, which is planned to be used in the year 2020. The company has played an important role in the finish of the first stage of global 5G standards.

Then I noticed a fire extinguisher (灭火器)，which I'd always wanted to shoot off.So this was the chance of a lifetime.I tried it，and，much to my surprise，the thing worked! It shot out a thick cloud of powder that instantly filled the room.I couldn't breathe.I was going to choke to death，and they'd probably never even find my body.Luckily，I remembered the ladder to the roof.I climbed up，popped the straw roof and saw a bright blue sky.I suddenly realised the dust and powder pouring out of the top could draw attention.So when the dust had settled，I climbed down and slipped out of the chained door.I'm not sure if I was more excited about being alive or about not being caught，but I ran all the way back home.【语篇解读】这是一篇记叙文，讲述了作者11岁时到废弃谷仓捣蛋的经历。
