To support myself and my education, I began to delivernewspapers.I would get up every morning at 5 am and walk five kilometers from Hydery to the newspaper office in Bazar. By 6am, I would collect 50 copies of newspaper which must have weighed over five kilos. After delivering them, I would rush home, another three kilometers away, cook my breakfast, eat quickly and go to school.One morning, I found a boy of my age at my doorstep. He introduced himself as Jimmy and said his parents wanted to see me. I guessed they wished to subscribe to (订阅) the newspaper, so I followed him to his place nearby.Jimmy's mother opened the door. She served me a large plate of snacks and fruit salad. It was a rich breakfast,one that brought back memories of the happy time with my parents. As I was about to leave, Jimmy's father,Mr. Kader, appeared with a new bicycle."This is for you!" He said, patting my shoulder."But I have no money!" I replied."Who is asking you to pay for this, my son?" He continued.It took me a few seconds to sense the warm moment. I didn't even realize my tears were rolling down myface. Jimmy's mother held me closely. It was like home, as if my mother were there.I bowed, thankfully, and left. This time, I didn't have to walk﹣I had the bicycle!The bicycle saved my life for many years thereafter and taught me a lifelong lesson: Help should always be need﹣based.(1)How did the writer support himself?A.

You should know that this habit is bad for your hearing, according to the World Health Organization (WHO).The human ear has three different parts. The outer ear is the part you can see. The middle ear and inner ear are inside your head. That doesn't mean those parts can't be hurt.They can be harmed by loud noises. Over one billion young people are at risk of hearing loss due to listening to loud noise for long periods of time, said WHO. Listening to music or watching a TV show at loud volumes can harm your hearing.Sounds are measured in decibels (dB分贝). A whisper is 30 dB. A friend talking is about 60 dB. The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB. The United Nations has standards for safe listening. It is not safe to listen to sounds that are louder than 85 dB for eight hours or 100 dB for 15minutes.Loud noise is harmful to the inner ear. Most of us are born with about 16,000 hair cells (听毛细胞) in our inner ears. These cells detect (探测) sounds. However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die. This is what causes hearing loss.Some people might think that their music isn't all that loud.But this can depend on where you are.For example, if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. Later, when you listen to it the same volume in a quiet place, you might feel uncomfortable.What can be done to protect your hearing? Use noise﹣canceling(降噪) headphones.These headphones get rid of background noise. You don't need to turn up the volume as much. Keep your device volume at 50 to 60 percent. Limit daily use of headphones. Listen to sound on your mobile devices for a maximum of one hour per day.The less loud noise you hear, the better!(1)Listening to loud music causes hearing problems because.A. it can stop our ears from restingB. it puts our brains under great pressureC. it can cause hair cells in the inner ear to dieD. it makes people get used to listening to loud sounds(2)From paragraph 5, we can know.A. people love to listen to loud musicB. people don't always know how loud their music isC. it's great to listen to music on the subwayD. it's reasonable to listen to loud music in some places(3)The writer probably agrees that.A. people have to wear headphones while walking on a busy roadB. listening to music on TV is better for hearing than on mobile devicesC. young people should set a time limit of listening to music at loud volumesD. wearing noise﹣canceling headphones can stop the outer ears being harmed17.(8分)Many students think about how to best spend their time while studying. But what we can do before study can be important too﹣especially if you want to improve your memory of what you have learned.ExerciseBefore you study, doing cardiovascular exercise(有氧运动)may help you better remember what youlearn. High﹣intensity exercise (高强运动) may be especially helpful. In a 2018 study, published in the journal Physiology and Behavior, researchers found that a group of young people who did 15 minutes of high﹣intensity training remembered more words.Some studies suggest the importance of different kinds of exercise. It seems that both long, slow cardiovascular exercise and high﹣intensity exercise have different effects on memory. Researchers have suggested combining the two to get the best effects for your memory.LocationLocation is also important for improving your learning. While it is good to have a desk or a special study area,some research suggests that changing where you study could help you remember more of what you study.Our memories sometimes depend on things in our environment.For example,a book might remind you ofsomething interesting or strange you learned while reading it."Environmental Context and Human Memory," a famous study on memory, dealt with the question of memory and our surroundings. Researchers Smith, Glenberg and Bjork found that environmental context played a big part in how well people remembered words.The researchers noted that subjects who learned from a list remembered an average of 15.9 words, while subjects who learned in two different contexts remembered an average of 24.4 words.Be sure to plan your location before you start to study.Pre﹣study testStudents often study with a test in mind. They think the test is the final step to show how much they havelearned. But taking a pre﹣study test is also important.In 2018, researchers found that students who took a test before learning new material did much better after studying the material. The research was published in the Journal of Experimental Psychology.So, try to take a pre﹣study test.We have explored three things you can do before study to improve your learning. In the future, we will explore things you can do during and after your study sessions to improve your learning.(1)According to the text, before you study may help you remember better.A. running 15 minutesB. sleeping for a whileC. reading English wordsD. drinking plenty of water(2)What's the meaning of "combining the two" in Paragraph 3?A. joining the two together to relaxB. doing the two things at the same timeC. doing the two things to work togetherD. joining the two together to make a single one(3)What can we learn from the passage?A. Pre﹣study test is more important than the final test.B. Researcher Smith suggests people remember words in a list.C. The researchers have explored what to do after the study.D. Environmental context can help improve human memory.(4)What would be the best title for the passage?A. Things to do before you studyB. How to spend your time while studying?C. How to improve your memory?D. Importance of studying your memory四、阅读短文,根据其内容回答问题.(共5分,每小题5分)18.(5分) Halloween is usually celebrated on October 31 or in the weekends before and after this date amongst family, friends and, sometimes, co﹣workers. In the UK, Halloween traditions are very popular. Here are some of the most common ones.Pumpkin lanternsThese are pumpkins with the insides taken out and eyes, a mouth and a nose cut into one side. A candle is placed inside the empty pumpkin. The light creates a "scary face" effect. People make pumpkin lanterns to decorate their homes and gardens on Halloween.But do people actually eat their pumpkins? Yes, they do! Pumpkin soup and pumpkin curry are very popular meals at this time of year.Dressing upPeople of all ages dress up on Halloween.The most popular costume(化装服)ideas include witches,vampires,ghosts, skeletons, zombies and monsters. You can buy a costume from a shop or make your own at home. It's easy to make a ghost costume from an old white sheet(床单) or wear black clothes to look like a witch.Trick﹣or﹣treatingThe custom of "trick﹣or﹣treat" appeared in the 1950s. It came from the US and is most popular among kid s. Children dress up in fancy costumes and visit the houses in their neighborhood asking for a "trick or treat". Their neighbors give them sweets or money as a treat.If there is no treat,the children play a trick on the neighbor. Some people think that playing tricks is rude(粗鲁的),but luckily, there is almost always a treat.People often have a bowl of small presents or sweets to offer to anyone who knocks on your door.Whether you decide to go to a Halloween party or go trick﹣or﹣treating, we hope you've got some ideas for celebrating Halloween.(1)Why do people make pumpkin lanterns?(2)How do people get a costume to dress up?(3)When did the custom of "trick﹣or﹣treat" appear?(4)Who gave the children sweets as a treat?(5)What is the passage mainly about?五、翻译句子(共5分,每小题1分)19.(1分)我为我的姐姐感到骄傲.20.(1分)你读书越多,越好.21.(1分)我们过去常常听收音机.22.(1分)除非你努力,否则不会成功.23.(1分)我告诉我的妈妈我会尽最大的努力成为一个好孩子.六、文段表达(10分)根据中文和英文提示,用英文写一封意思连贯、符合逻辑、不少于50词的文段.文中已给出内容不计入总词数.所给提示词语仅供选用.请不要写出你的校名和姓名.24.(10分)在成长的路上,我们难免会遇到各种问题或困难,比如生活中的、学习中的、与父母同学交往中的…….有没有哪一次的经历让你印象深刻.某英文网站正在开展以"走出困境"为主题的征文活动.假如你是李华,请你用英语写一篇短文投稿,主要内容包括:你遇到了什么问题,你是如何解决这个问题的以及你的感受.提示词语:problem,
