It was because that reason that the earth was thought to be the centre of the solar system. Copernicus had thought long and hardly about it and tried to find an answer. But, all his mathematical calculations led to the same conclusion what the earth was not the centre of the solar system. When he placed a fixed sun at the centre of the solar system, the movement of the other planets made the sense. The Christian Church rejects his theory.

Unlike them，I had no ear for music and languages. I was not an early reader and I could not do mental maths.I have only the unmemorable memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents，aunts，uncles and cousins who gathered next door. But I do have a crystal clear memory of the dogs, the farm animals，the local birds，and above all the insects.I am a naturalist，not a scientist. I have a strong love of the natural world，and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil while reading about other peoples observations and discoveries. Then something happens that brings these observations together in my conscious mind. This has resulted in my publishing 300 papers and books，which some might honour with the title of scientific research.But curiosity，a keen eye，a good memory and enjoyment of the animal and plant world do not make a scientist：One of the outstanding and essential qualities required is selfdiscipline, a quality I lack. A scientist requires not only selfdiscipline but all training, determination and a goal. A scientist，up to a point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.【语篇解读】本文是一篇夹叙夹议文，作者通过自身的经历明白了一个道理：博物学家是天生的，而科学家则是可以后天培养的。1What impressed the author deeply during his childhood?AWildlife.BMusic.CLanguages.DLiterature.A细节理解题。根据第三段最后一句“But I do have a crystal clear memory of the dogs, the farm animals, the local birds, and above all the insects”可知，作者在童年时，印象深刻的是那些野生生物，故选A。2Why cant the author remember his relatives clearly?AHe didnt live with them for long.BThe family was extremely large.CHe was fully occupied with observing nature.DHe was too young when he lived with them.C推理判断题。根据第三段最后一句“But I do have a crystal clear memory of the dogs, the farm animals, the local birds, and above all the insects”可推知，作者童年时期过于专注自然界而对周围的亲戚并不是很在意，所以没有深刻的印象，这与第四段第二句中的“I have a strong love of the natural world”呼应，故选C。3According to the author，what personality should a born naturalist have first of all?ABeing knowledgeable.BBeing selfdisciplined.CBeing full of ambition.DBeing full of enthusiasm.D推理判断题。根据第四段前两句“I am a naturalist, not a scientist. I have a strong love of the natural world，and my enthusiasm has led me into varied investigations”可知，作者从小热爱自然界，而且这种热情使作者做了很多不同的调查，成了一个博物学家。由此可推知，一个天生的博物学家首先要充满热情，故选D。4Why does the author say he is a naturalist, not a scientist?AHe thinks he lacks some quality required of a scientist.BHe thinks he has much trouble doing mental arithmetic.CHe thinks he comes up with solutions in a most natural way.DHe thinks he just reads about other peoples observations.A细节理解题。根据最后一段第一句“But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist：One of the outstanding and essential qualities required is selfdiscipline，a quality I lack”可知，作者认为自己只是一个博物学家而不是一个科学家是因为自己缺乏成为科学家的必备素质，故选A。B(2019安徽省五校联盟第二次质检)While an entire month free of homework or tests may sound too good to be true, that is exactly what the students at Sturenskolan School in Boden, Sweden were treated to in April. Whats more, if the results of the experiment prove encouraging, starting 2019, the middle schoolers will never have to worry about afterschool work or tests, aside from the national examinations, which are compulsive for students across the country.The schools principal, Petronella Sirkka, who came up with the idea, said, “We are constantly receiving new reports that our children feel bad. And thats because they have a high level of stress all the time. This is our way of trying to reduce that stress.”The educator says that while banning homework and tests sounds radical(激进的), it makes sense given the changes in the curriculum and approaches to education. While in the past students were primarily subjected to memorizing facts, learning today is all about reflection and analysis. As a result, it is often harder for kids, especially those with little support at home, to comprehend the material by themselves.Sirkka is not the only one who believes afterschool work does not help students learn. In March 2018, another principal in Canada also decided to do away with homework. They hope parents will spend the extra time reading to their kids.While the longterm impact of the recent decisions made by the two educators remains to be seen, the experiment has already proved successful in Finland which has done away with homework, grades, and even teaching by subjects for many years. Yet, Finnish students always rank high in the PISA (Programme for International Student Assessment) tests especially in math and science but they have the least homework! Hopefully, it will only be a matter of time before US educators follow their lead and ban afterschool work as well!【语篇解读】本文是一篇说明文。瑞典一所学校在四月份取消了学生的家庭作业和考试，这是该校校长Petronella Sirkka看到学生作业负担太重而提出的举措，且芬兰采取的类似做法已获成功。5The students at Sturenskolan School had no homework in April because Athe headmaster was experimenting with her ideaBthey needed to do some experiments during the monthCthey were busy preparing for the national examinationsDthe headmaster had to carry out the governments policyA细节理解题。根据第二段第一句中的“The schools principal，PetronellaSirkka，who came up with the idea”，并结合第一段的内容可知，Sturenskolan学校的学生们在四月份没有家庭作业和考试是该校校长提出的想法，故A项正确。6What makes childrens learning hard nowadays?AChildren have to do more analyzing.BThe approach to education is complex.CChildren get no support at home and school.DThere are many more facts to memorize.A细节理解题。根据第三段第二、三句“While in the past students were primarily subjected to memorizing facts, learning today is all about reflection and analysis. As a result, it is often harder for kids, especially those with little support at home，to comprehend the material by themselves”可知，在过去，学生主要是被要求记住事实，而如今学生需要的是反思和分析。因此，孩子们往往很难自己理解这些材料。据此可知，反思和分析让孩子们的学习更加困难。故A项正确。7What does Petronella Sirkka most likely advise parents to do?AHelp children with their homework.BFree children from afterschool housework.CSpend more time reading to their children.DCommunicate with teachers from time to time.C推理判断题。根据第四段尾句“They hope parents will spend the extra time reading to their kids”可推知，Petronella Sirkka很可能会建议父母花些时间为他们的孩子们阅读，故C项正确。8What can we infer about the students in Finland?AThey study the hardest at school.BThey have a more relaxing school life.CThey enjoy great success after graduation.DThey all have a talent for math and science.B推理判断题。根据尾段第一句中的“the experiment has already proved successful in Finland which has done away with homework, grades, and even teaching by subjects for many years”可知，多年来，芬兰已经取消了家庭作业、成绩等级，甚至科目教学。据此可推知，芬兰学生的学校生活更加轻松，故B项正确。.完形填空(2019成都市第二次诊断性检测)Earlier that evening, my mother called, telling me that my brother died in a car crash.
