Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (视力综合症).Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. “More children come into my office because their parents have noticed that they have headaches (头疼)or red eyes, or because their degree of short-sightedness appears to be increasing (增加)very fast and they’re worried,” he said.Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away. Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.41．Which of the following may be caused by too much screen time?A．Having wet eyes. B．Having headaches.C．Having small eyes. D．Having a toothache42．Why don’t some children tell their parents when their eyes start to feel uncomfortable? A．They think it is not serious.B．They want to continue playing computer games.C．They don’t want their parents to worry.D．Their parents don’t care about them.43．People blink about as they normally do when they use computers.A．a third as much B．two thirds as muchC．half as much D．as much44．From the passage, we can learn that .A．children should blink as much as possibleB．tears can’t protect eyesC．blinking is good for eyesD．It’s useless to blink.45．What is the passage mainly about?A．Some information about the latest digital products.B．Dr. Warford’s experience of working out eye problems.C．Eye problems in children caused by using digital products.D．It’s bad to use computers .四、回答问题阅读表达If you lose 12 times in a row (连续地), will you just give up? Dale Carnegie, a pioneer in public speaking and self-development, kept trying. And he became famous by showing people how to be successful.Carnegie was born into a poor family in th e United States. The boy didn’t see a train until he was 12 years old. In his teens, he had to get up at 3 am every day to milk the cows for his family.When Carnegie first entered college, he felt upset because of his ragged (破旧的) clothes and ordinary(平凡的) looks. His mother encouraged him, “Why not try to be better in other things instead of just dress and good looks?”Carnegie tried to be more active in college. He joined the debate (辩论) team. But one after another, he lost 12 competitions. The young man was very disappointed with himself. He said later that he thought of killing himself after failing so many times. But soon Carnegie was seen practicing public speaking on the riverside. His hard work paid off at last. In 1906, Carnegie won a famous speech contest and became well-known. “Believe that you will succeed, and you will,” he said.In order to share his success, Carnegie opened schools and wrote books. Hisbest-sellers(畅销书) include How to Win Friends and Influence People and How to Stop Worrying and Start Living. More than 50 million copies of his books have been translated in 38 languages. They are still helping people on the road to success.46．What did Carnegie have to do every morning in his teens?_______________________________________________________47．Why did Carnegie feel upset when he first entered college?_______________________________________________________48．What did Carnegie do to be more active in college?_______________________________________________________49．How did Carnegie share his success?_______________________________________________________50．What should we do if we fail so many times?（至少2点）______________________________________________________五、填空During their lives, many people experience difficulties and struggle (努力) to do something. When I lived in China, it was a hard struggle for me to learn Chinese and get used to Chinese customs.The first day I went to school, I didn’t understand what my teachers and my classmates said. I just sat in my seat without doing anything, but when I went back home, I cried and told my mom that I wanted to leave for my homeland.Later, however, I decided I had to study Chinese very hard, but it was very difficult to learn the language. Every day at school, I tried to talk to the Chinese students and make friends with them. When school was over, I studied Chinese at home by watching Chinese TV programs. That turned out to be a very good way to improve my Chinese. Little by little, I began to speak Chinese in school and I began to make many friends. Finally, I got a very high grade in the Chinese exam and naturally I became used to Chinese customs.Now, I like to talk with Chinese people and I like Chinese food too. The experience of struggling to learn Chinese in China was unforgettable, and I’ll never forget the time when I learned so much.六、根据句意填空词汇（共10小题，每小题1分，计10分）A．根据中文和句意写出单词，完成句子。
