They brought different dialects (方言) of English with them. These different kinds of English began to mix and change. The newcomers soon began to speak with their own typical accent (口音) and vocabulary. More and more people came to Australia during the Gold Rush in the 19th and 20th centuries. Some came from Britain and Ireland; others came from non-English speaking countries. Australian English continued to grow and change.Australian English has also been influenced by American English. During the Second World War, there were many American soldiers staying in Australia. More importantly, American television shows and music have been popular in Australia since the 1950s.Australians use many words that other English speakers do not use. The famous Australian greeting, for example, is G’day! A native forest is called the bush and central Australia is called the outback. Many words were brought to Australia from Britain and Ireland. For example, mate means “friend”, and it is still used in Britain. Some of these words have changed in meaning. Some words have come from Australian original languages, many of which are names for animals, plants and places, like dingo and kangaroo.Australian spelling comes from British spelling. In words like organise and realise, -ise is the expected and taught spelling method. In words like colour, favourite, -ouris the normal, but nouns such as the Labor Party and Victor Harbor are spelled with -or. Program, on the other hand, is more common than programme.There are also differences in the definition (定义) of words Australians use in different parts of the country. For example, football means “rugby” in New South Wales and Queensland, but “Australian rules football" in everywhere else in Australia. In New South Wales, a swimming costume is called a cossie or swimmers, while in Queensland it is called togs and bathers in Victoria.4. What does paragraph 1 mainly talk about?A. Reasons why English is important.B. Different dialects of Australian English.C. Various aspects that Australian English has been influenced.D. Changes of the accent and vocabulary in English.5. According to the text, which of the following is spoken only by Australians?A. Mate.B. Outback.C. Program.D. Rugby.6. Which is the following can best describe Australian English?A. Confusing and interesting.B. Multicultural and creative.C. Crazy and boring.D. Unchangeable and mixed.7. What might be the best title for the text?A. The History of AustraliaB. The Birth of Australian EnglishC. The Development of Australian EnglishD Different Kinds of English Across the WorldCA North Atlantic right whale calf(幼崽) was discovered dead on the beach of an island off North Carolina. The male newborn was found on North Core Banks, part of the Cape Lookout National Seashore. The reports indicate that the animal died during birth or shortly after, according to the National Oceanic and Atmospheric Administration(NOAA). Scientists took DNA to determine the calf’s mother.This is the beginning of the right whale’s reproduction(繁殖) season, which begins mid-November and runs through mid-April. NOAA called this death a disastrous start to the season. Each new right whale calf brings so much hope for this badly endangered animals, and losses like this have a great impact on their recovery, NOAA said.The right whale is one of the rarest marine mammals(哺乳动物) in the world, according to NOAA. They will soon be extinct unless something is done to save it, researchers warn. This kind of whale has been experiencing an Unusual Death Event over the past three years, according to NOAA. Since 2017, at least 32 dead and 13 seriously wounded whales have been documented by the organization. “This means more than 10 percent of the remaining population,” according to NOAA.NOAA posted a piece of news on Monday, the same day they announced the calf’s death, warning boaters to be watchful as the whales are migrating(迁徙) nearly 1,000 miles along the Atlantic Coast. The organization calls for boaters to be watchful, slow down and to give these endangered whales plenty of room. They also ask all fishermen to remove their unused nets from the ocean to help avoid possibledamage.8. Why did scientists take DNA of the calf?A. To save its mother.B. To confirm its identity.C. To determine the time of its death.D. To uncover the cause of its death.9. How many right whales are left according to the passage?A. About 40.B. About 50.C. About 400.D. About 500.10. What do we know aboutNorth Atlanticright whales?A. Their reproduction season usually last about half a year.B. They are the rarest marine mammals in the world.C. They are experiencing a high death rate of newborns.D. Their habitat runs nearly 1,000 miles along the coast.11. What’s the main purpose of the news posted on Monday?A. To announce the calf’s unusual death.B. To remind boaters to watch the whales.C. To protect the boats against the whales.D. To assist the whales’ seasonal migration.DAddiction to smartphones will result in poor sleep, according to a new study.The study, published Tuesday in Frontiers in Psychiatry, looked at smartphone use among 1,043 students between the ages of 18 and 30at King's College London. Researchers asked the students to complete two questionnaires on their sleep quality and smartphone use, in person and online.Using a 10-question scale that was developed to judge smartphone addiction in children, nearly 40% of the university students qualified as "addicted" to smartphones, the study found. “Our findings are in agreement with other reported studies in young adult populations globally, which are in the range of 30-45%,” lead author Sei Yon Sohn and her co-authors wrote in the study. "Later time of use was also significantly connected with smartphone addiction, with use after 1 a.m. increasing a 3- times risk," the authors wrote.Students who reported high use of smartphones also reported poor sleep quality, the study found. That foils in line with previous studies that have found overuse of smartphones at night to be associated with trouble falling asleep, reduced sleep duration (睡眠持续时间)and daytime tiredness. That's likely because use of smartphones close to bedtime has been shown to delay the body's normal sleep - and - wake clock.In fact, the No. 1 rule is "no computers, cell phones, and ipads in bed and at least one hour beforebed Dr. Vsevolod Polotsky, who directs sleep basic research, said in a recent interview. That's because "any LED light source from electronics (电子设备)may further hold back melatonin (褪黑激素)levels," Polotsky said.

2021年湖北省黄冈中学高三英语第四次联考试题及答案

2021年湖北省黄冈中学高三英语第四次联考试题及答案

2021年湖北省黄冈中学高三英语第四次联考试题及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AWhen the weather is bad or when the flu breaks out, we can let the kids do some fun things at home, which can be beneficial to kids.Reading out loudIf your children are young enough, don't forget to read books to them out loud! Few children dislikehaving a good book read to them, and it's great for the development of their brains. However, if your children are a bit older and have moved onto more advanced books, there is always the choice of listening to an audiobook. This can also be done while they're doing something else.Playing board gamesMaybe your children's table is full of board games, which have been forgotten for a long time. It's a good time to bring them out when playing outside is no longer a choice. Surely, playing board games is a great way to connect with children. In addition, many board games are designed to get children thinking!Having a dance partyConsidering that all you need is a speaker or maybe just a phone, you can have a dance party wherever you are! This is a great way to get kids’ bodies moving when they are inside. Play some of your children's favorite music and let them dance to it. Not only is it good exercise, but it will help your children feel time is flying!Doing jigsaw (拼图) puzzlesFor most people that have children, it's common to have at least one jigsaw puzzle at home. Jigsaw puzzles are great because everyone can do them on their own time. Besides, your whole family will have a sense of achievement when everyone is smiling over the finished product.1. What do reading out loud and playing board games have in common?A. They both develop children's team spirit.B. They both improve children's listening ability.C. They both do good to children's thinking ability.D. They both focus on interaction between children.2. Which of the following combines exercise and music?A. Reading out loud.B. Playing board games.C. Doing jigsaw puzzles.D. Having a dance party.3. What is the purpose of the text?A. To list four interesting children's parties.B. To recommend four children's favorite books.C. To introduce some activities for children inside.D. To show some funny things for children outside.BWhen I was a kid, my mom set aside some breakfast food for supper every nowand then. I remember one night after a long, hard day at work, my mom placed a plate of eggs, sausage, and a plate of extremely burnt biscuits on the table. I waited to see if my dad would get annoyed.All my dad did was to reach for the biscuits, smile at my mom and ask me how my day at school had been. I don't remember what I told him that night but I do remember watching him add butter and jelly on that ugly burnt biscuit and ate every bite of that thing. He never made a face nor uttered a word about it!When I rose from the table that evening, I remember hearing my mom apologize to my dad for overcooking the biscuits and I will never forget what he said, “Honey, I love burnt biscuits every now and then."Later that night, I went to say good night to my daddy, and I wondered if he really liked his biscuits burnt. He wrapped me up in his arms and said gently, "Your mom put in a hard day at work today and she is really tired. Besides, a little burnt biscuit never hurt anyone!As I have grown older, I've thought about that many times. Life is full of imperfect things and imperfect people. Learning to accept each other's faults and choosing to celebrate each other's differences contribute to a healthy, growing, and lasting relationship. We could extend this philosophy to any relationship, such as a husband-wife, parent-child, or friendship. Don't put the key to your happiness in someone else's pocket. Keep it in your own. So, please pass me a biscuit, and yes, the burnt one will do just fine.4. How did the author's dad react to the burnt biscuit?A. He set it aside for breakfast.B. He ate butter and jelly instead.C. He uttered his complaints loudly.D. He ate it up as if nothing happened.5. Which of the following words can best describe the author's dad?A. Caring.B. Determined.C. ProudD. Hardworking.6. What does the author suggest people do in the last paragraph?A. Show understanding to imperfect things.B. Ask the children to respect their parents.C. Enjoy the over-cooked biscuits willingly.D. Make important decisions on your own.7. In which section of a magazine may this passage appear?A. History and culture.B. Family and relationship.C. Cuisine and health.D. Entertainment and sports.CThe market for tourism in remote areas is booming as never before. Countries all across the world are actively promoting their wilderness regions-such as mountains, Arctic lands, deserts, small islands and wetlands— to high-spending tourists. The attraction of these areas is obvious: by definition, wilderness tourism requires little or no initial investment. But that does not mean that there is no cost.Once a location is established as a main tourist destination, the effects on the local community are profound. Hill-farmers can make more money from foreign travellers than working in their fields. It is not surprising that many o£ them give up their farm-work. In some hill-regions, this has led to a serious decline in farm output and a change in the local diet, because there is lacking labour to maintain terraces and irrigation systems. The result has been that many people in these regions have turned to outside supplies of rice and other foods.InArcticand desert societies, year-round survival has traditionally depended on hunting animals and fish and collecting fruit over a ly short season. However, as some inhabitants become involved in tourism, they no longer have time to collect wild food; this has led to increasing dependence on bought food and stores. What should they do if these new sources of income dry up?The physical impact of visitors is another serious problem associated with the growth in adventure tourism. Much attention has focused on erosion along major roads, but perhaps more important are the forest destruction and impacts on water supplies arising from the need to provide tourists with cooked food and hot showers. In both mountains and deserts, slow-growing trees are often the main sources of fuel and water supplies may be limited through heavy use.8. Why are some countries promoting the wilderness regions to tourists?A. The wildness regions are accessible to tourists.B. The landscapes there are beautiful and unique.C. Developing tourism there doesn't need much investment.D. Lots of high-spending tourists prefer such remote regions.9. What is the effect of tourism on the local community?A. Many hill farmers have turned to outside supplies of foods.B. There is enough labour to maintain terraces and irrigation systems.C. Farm output there has increased and local diet has changed.D. The local people's new sources of income will dry up soon.10. Which might be the best title of the passage?A. The future of wilderness tourism.B. The impacts of wilderness tourism.C. The destruction of wilderness tourism.D. The disadvantages of wilderness tourism.11. If there is one more paragraph following the last paragraph, what will it talk about?A. The effects on local people.B. The solutions tothese problems.C. The choices of adventure tourists.D. The reasons for visiting remote areas.DPeggy Whitson's job demands a daily two­hour workout in a gym where weight has no meaning and the view changes at 17,000 miles an hour.Whitson makes it look easy. At 57, she is the oldest woman to fly in space, breaking the record last November, 2016, when she began her third long­term stay at the International Space Station. After returning home in September, 2017, the NASA astronaut feltmatter­-of­-factabout the age milestone.“It wasn't a record I was seeking for,” Whitson said. “I was 42 and 48 for my first two space flights. I feel lucky that I was able to get to do another one in my 50s. I don't think people should let age discourage them, even on those jobs that require some amount of physical fitness. The oldest man is John Glenn (at 77), and we've had male astronauts in their 60s before, so it's just a matter of time before women start flying in space at this age”.On the earth, she stays fit by weightlifting, biking, playing basketball and water skiing. She shared what it's like to live in microgravity: “It's like you're in a swimming pool, but you don't have to worry about breathing. If I push off from one side, I'm going to float to the other side. Every direction feels exactly the same, which is really hard for your brain to grasp, but it's amazing how fast you adapt.It's a big shock for the body to come back to Earth—everything is so heavy. We spend a lot of time getting used to being back in gravity again. Back pain was really the most dramatic for me this time. For me, coming home isharder than going up into space.”12. How long did Peggy Whitson spend for her third stay in the International Space Station?A. About 300 days.B. About 708 days.C. About 107 days.D. About57 days.13. What does the underlined word probably mean in the passage?A. Amazing.B. Not surprising.C. Enthusiastic.D. Unbelievable.14. According to the passage, which of the following is true?A.
