Tough Man: a race to the limitEvery January, more than 3, 000 people take part in one of the most difficult races on Earth: the Tough Man competition in the UK． Competitors run, swim and climb around the 15﹣km course． But this is no normal race． These competitors have to crawl （爬）through tunnels （隧道）, run across a field of nettles （荨麻） and jump overfire． What's more, the competition takes places in January, so the temperatures are low ﹣sometimes as low as ﹣6 ℃． People travel from all over the world to take part, with competitors from South Africa, Australia and China．The following shows what the Tough Man course is like． First, competitors run for 1km along a muddy road． Next, they crawl under low nets on the ground． After the nets, the runners jump into a lake and swim for 1km． Then, they reach the field of fire． Here, the runners run across a field and jump over small bonfires． Next, competitors must crawlthrough a long tunnel． The tunnel is partly under water． Finally, the runners run 2 km through nettles before they reach the finish line．The competition is quite dangerous and every year there are accidents． Injuries like broken bones and cuts are quite common． The race is very hard: one﹣third of the competitors don't finish it． Runners have to be very fit and healthy and most people trainall year to prepare for the event． It is also the only race like it in the world． There are similar events, but this was the first one in the world． Many people do the competition because it is so famous． Every year the organizers change the event and add new things． This means that the competition stays exciting and challenging, so people go back year after year．（1）Where does the Tough Man competition take place？________A In the UK．B In China．C In Australia．D In South Africa．．（2）What do competitors do after crawling under nets？________A Run across a field with fire．B Jump into water and swim．C Crawl through a tunnel．D Run through nettles．．（3）Why do people go back to the competition every year？________A It changes and stays exciting every year．B It is the first competition in the world．C It helps people to stay fit and healthy．D There are no similar eventslike it．16. FOMOEverybody knows how important it is for students to get a good night's sleep every night． You aren't able to do your best and keep up with all of your responsibilities at school unless you sleep well． Most experts agree that the best number of sleeping hours iseight, and this has been accepted as common sense for as long as I canremember． However, I was young once and I know that most of you get much less sleep than that ﹣ and in some cases it will be influencing your schoolwork．I read an interesting article in a teachers' magazine recently． They did a study of848students in Wales． Worryingly, the results showed that teenagers are facing a new problem． They may go to bed and get up at proper times but a growing number of them are waking up in the middle of the night, not to use the bathroom or have something to eat but because of FOMO﹣ fear of missing out, which brings worrying influence on their sleep and schoolwork．According to the article, schoolchildren are having problems because more and more of them wake up during the night to check social media． Afraid of missing a comment （评论）or an opportunity to take part in a conversation, teenagers are waking at all times of the night, going online and getting involved． All this when they should be sound asleep．Experts are worried and the report shows some facts from the study that I'd like to share with you:23% of 12 to 15﹣year﹣olds wake up nearly every night to use social media．One in three students are always tired．Students who use social media during the night are more likely to be anxious （焦虑）．Are you experiencing FOMO? If yes, I'd like to ask you to be responsible for your sleep when it comes to social media． Be brave! Switch off your devices （设备） at night． The world won't end and your social media will be waiting to greet you in the morning! I give you my word that you won't have missed anything important just because of a good night's sleep．（1）We can learn from the passage that FOMO is ________．A an unreasonable need to go out all the timeB a result of using social media in a wise wayC a fear of missing communication on social mediaD a study on the ways of teenagers using social media．（2）What did the study in Wales show？________A Teenagers are tired because they often stay up late．B More and more teenagers are tired of schoolwork．C Half of the teenagers wake up nearly every night．D Using social media at night may cause anxiety．．（3）What is the writer's main purpose in writing this passage？________A To explain the relationship between FOMO and sleep．B To encourage teenagers to deal with FOMO properly．C To describe why teenagers don't get enoughsleep． D To show why FOMO happens a lot to teenagers．17. Think back to when you were in a classroom, and the teacher set a difficult problem． Which of the two following responses is closer to the way you reacted?The psychologist （心理学家） Carol Dweck of Stanford University, did a test by giving some ten﹣year﹣old children problems that were a little hard for them． Group 1, who chose B, reacted positively, said they loved challenges and understood that their abilities could be developed． Professor Dweck says they had a "growth mindset （思维模式）"． And they cared more about what they can achieve in the future． However, group2, who chose A, felt that their intelligence was being judged and they had failed． They hada "fixed mindset" and were unable to imagine improving． Some of these children said they might cheat in the future and look for someone who were worse than them, just to make themselves feel good．Professor Dweck believes that there is a problem in education． For years, teachers have praised children for their intelligence and talent． But this makes them get hurt easily from failure． They become performance﹣oriented （i．e． interested in getting highgrades, not learning）． The right way, according to Dweck, is to praise the process that children are involved in: making an effort, using learning strategies （策略） and improving． This way they will become mastery﹣oriented （i．e． interested in getting better at something） and will achieve more．Psychologists have been testing these theories． Students were taught that if they lefttheir comfort zone and learned something new and difficult, they'd be moreintelligent． These students made faster progress than a control group． In another study, children from an underperforming （不佳的） school had trainings on their growth mindset techniques for a year．The results were ________． They came top in tests, beating children from much better schools． These children had previously felt that making an effort was a sign of stupidity, but they came to see it as the key to learning．So, back to our original question, if you answered B, well done ﹣ you already have a growth mindset． If A, don't worry; everyone is able to become mastery﹣oriented with a little effort and self﹣awareness．（1）What can we learn from Carol's test in Paragraph 2？________A Group 2 cheated in the test．B Group 1 had good imagination．C Group 2 felt confident after the test．D Group 1 liked challenging problems．．（2）What does Paragraph 3 mainly talk about？________A Ways of training children．B How to deal with challenges．C Problems in today's classroom．D The right and wrong ways of praise．．（3）The word ________in Paragraph 4 probably means________．A unbelievableB unchangeableC disappointingD frightening．（4）Which of the following would be the best title for the passage？________A Do you have the right mindset？B Can you make the right choice？C Are you using proper strategies？D Are you really pushing yourself？．四、阅读短文，根据短文内容回答问题．（共 10 分，每小题 2 分）18.Tornado ChaserDo you know？ In June 2003， South Dakota experienced 67 tornados in one day! In the U．S．， tornadoes （龙卷风） are responsible for 80 deaths and more than 1，500 injuries each year． Although they happen very often， tornadoes are difficult to predict． Why？Tornadoes develop from storms， but only some storms can becometornadoes． Meteorologists （气象学家） don't know where and when a storm will touch the ground and turn into a tornado． Today， the warning time for a tornado is usually just 13 minutes．Tim Samaras is a tornado chaser． His job is to find tornadoes and follow them． When he gets close to a tornado， he puts a special tool on the ground． This tool measures things like temperature， humidity， and wind speed of a tornado． With this information，Samaras can learn what causes tornadoes to develop． If meteorologists understand this，they can warn people about tornadoes sooner and save lives．How does Samaras hunt tornadoes？ It's not easy． First， he has to find one． Tornadoes are too small to see using weather satellites （卫星）． So Samaras can't just depend on these tools to find one． Instead he waits for tornadoes to develop． Every May and June，Samaras drives about 40，000 kilometers （25，000 miles） across an area known as Tornado Alley， looking and hoping to find a tornado．Once Samaras sees a tornado， the chase begins． But a tornado is hard to follow． Some tornadoes change direction several times﹣for example， moving east and then west and then east again． When Samaras finally gets near a tornado， he puts his special tool on the ground． Being this close to a tornado is frightening． There is rubbish flying in the air． The wind is blowing at high speed． He must get away quickly．The work is risky， even for a skilled chaser like Samaras． But danger won't stop his hunt for the perfect storm．（1）When did South Dakota experience 67 tornadoes in one day？________（2）How long is the warning time usually for a tornado？________（3）What does Tim Samaras do？________（4）Where does Samaras go every May and June？________（5）Why is it hard for Samaras to hunt tornadoes？________五、书面表达（共 10 分）文段表达（10 分）从下面两个题目中任选一题，根据中文和英文提示，完成一篇不少于 50 词的文段写作．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．19. 根据中文和英文提示，完成一篇不少于 50 词的文段写作．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．庙会是春节期间最传统的活动之一．假如你是李华，打算邀请你校的美国交换生 Peter 于 2 月 5 号一起去逛庙会（the Temple Fair），感受中国传统文化的魅力．请你用英语写一封邀请信，告诉他你们见面的时间、地点，以及他需要做哪些准备．提示词语： traditional activity， 9o'clock， warm clothes， camera提示问题：● When and where are you going to meet？● What do you advise Peter to prepare？Dear Peter，How is it going？I'm writing to invite you to come to visit the Temple Fair during Spring Festival holidays．I'm looking forward to your early reply．Yours， Li Hua20. 根据中文和英文提示，完成一篇不少于 50 词的文段写作．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．某英文报社就"服务社区"的话题展开征文活动．假如你是李华，应学校要求，你参加了为社区服务的活动．请你用英文写篇短文给报社投稿，谈谈你参加此次活动的经历及感受．提示词语：collect rubbish， visit old people， proud， meaningful提示问题：● What did you do to help in the community？● How did you feel about the activity？I went to help in the community during summer holiday．2018-2019学年北京市石景山区九年级（上）期末英语试卷答案1.

2018届九年级上学期期末考试英语试题（北京市石景山区含答案及mp3听力）石景区pet owners Being mentally active and doing physical exercise are also very important lifestyle habits Studies of very old people, however, don’t always support the scientific theories Many old people don’t eat healthily and don’t do much exercise Jeanne Calment, the world’s oldest person ever, certainly goes against scientific ideas She was born in France in 1875 and died aged 122 Did she use to have good lifestyle habits? Well, according to scientists, she had some very good habits she did plenty of physical exercise and used to ride a bicycle until she was 100 She was good at thinking positively and she didn’t use to worry about things Scientists are surprised, however, by one of her other habits she didn’t used to eat very healthily She used to eat more than two pounds of chocolate a weekSo there is another factor involved in holong we live Scientists nothink that some people were born with genes (基因) that protect them from aging and diseases better than other people For example, Jeanne Calment probably had a gene that stopped her from getting cancer (癌症) that other people may get aged forty or fifty Some scientists believe that we can change our genes by eating a low-calorie diet Experiments with mice shothat when they eat one third fewer calories every day, they live forty percent longer In human terms, that’s the same as living to 170 years old There’s no proof that it works in human, however, and perhaps it’s best to enjoy the days you’ve got rather than be hungry all your life!。
