1、2021 届中山市中山市濠头中学高三英语期中考试试卷及答案解析 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 A AQUILA Childrens Magazine is the most intelligent read for curious kids.Full of enthusiastic articles and challenging puzzles,every issue covers science,history and general knowledge.A
2、QUILA is a quality production,beautifully illustrated with contemporary artwork throughout.Intelligent reading for 8-12 year-olds Cool science and challenging projects Inspires self-motivated learning Exciting new topic every issue AQUILA is created and owned by an independent UK company.It has 28 p
3、ages,printed on high-quality paper and there are no advertisements or posters.Instead it is full of well-written articles,thought-provoking ideas and great contemporary artwork.Each monthly issue is centred around a new topic.AQUILA works as a superb learning extension to current primary(or KS2 and
4、KS3)curriculum(课程),but it is much more than that!Entertaining and always surprising,AQUILA is recommended because it widens childrens interest and understanding,rather than encouraging them to concentrate only on their favourite subjects.It gives children a well-rounded understanding of the world,in
5、 all its complexity.The concepts in AQUILA can be challenging,requiring good comprehension and reading skills.8 years is usually a good age to start.Some gentle interest from an adult is often helpful at the start.In 2020 AQUILA will have been in publication for 28 years,but it has never appeared in
6、 newsstands or shops.We are subscription only.AQUILA Subscription UK:12 Months 55-4 Months 30 Europe:12 Months 60-4 Months 35 World:12 Months 70-4 Months 35 Birthdays Select the Birthday option,write a gift message and choose the birthday month.We will dispatch to arrive at the start of the month yo
7、u have entered.The package posts in a blue envelope marked Open on your birthday.1.What is special about AQUILA?A.It is available in shops.B.It is for kids of all ages.C.It has no advertisements.D.It prints readers artworks.2.What does AQUILA offer its readers?A.Articles on modern art.B.Family readi
8、ng materials.C.Ideas on improving readingskills.D.Knowledge beyond school subjects.3.AQUILA is intended for _.A.foreign language learners B.children with learning difficulties C.parent-child reading lovers D.curious kids with good comprehension B Humans are the only creature that gets around by stan
9、ding up and putting one foot in front of the other.Our ability to walk upright has allowed humankind to travel great distances and survive changing climates,environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number
10、 of healthimplications,which help people live longer.In fact,a walking routine,if done properly,might be the only exercise people need.How much walking should one aim for?Youve likely heard we need 10,000 steps a day.Thats about 5 miles.But contrary to popular belief,this recommendation doesnt come
11、from science.Instead,itis from a 1960s advertising campaign to promote a pedometer(计步器)in Japan.Perhaps because its a round number and easy to remember,it stuck.Since the 1960s,researchers have studied the 10,000-steps-a-day standard and have turned up mixed results.Although 10,000 steps is certainl
12、y a healthy and worthwhile goal,its not fit for all.For instance,a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women.The study also noted that thes
13、e benefits continued up to 7,500 steps.This 7,500 mark isnt surprising:Its similar to common public health recommendations,such as the Centers for Disease Control and Preventions recommendation of 150 minutes of moderate(适度的)physical activity a week for adults.4.What does the underlined word“implica
14、tions”in Paragraph 2 refer to?A.Benefits B.Problems.C.Habits.D.Manners.5.Where does the 10,000-steps-a-day standard come from?A.A Harvard University study.B.Science research on health.C.A pedometer advertisement.D.Public health recommendation.6.What can we know from the last paragraph?A.7,500-steps-
15、a-day standard is the best choice for all.B.More than 16,000 old people were involved in the study.C.Those who walk at least 4,400 steps a day wont die early.D.150-minute moderate exercise a week for adults is advised.7.What does the author mainly want to tell readers?A.The more you walk a day,the h
16、ealthier you will be.B.We can benefit from continuous and proper walking.C.Walking upright helps humankind to explore the world.D.Advertisements can always tell us some scientific suggestions.C Some years ago a young man applied to a large United States optical firm for a job as a lens designer.He a
17、pologized for lack of training,but on announcing that he owned two copies of the classic Conradys Applied Optics and Optical Design,one for his office and a second for his bedside table,he was hired on the spot.Perhaps the story will be repeated some day with Buchdahls Introduction to Hamiltonian Op
18、tics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as black boxes,although it does not describe the detailed structure needed to construct the systems and achieve these properties.Buchdahls book is
19、 therefore on the subject of geometrical optics,but it is not about how to design lenses.It is,however a compact comprehensive account of the fundamentals of the theory written with the lens designers needs very much in mind.Every lens designer worth his salt has at some time in his career attempted
20、 to apply the broad concepts of Hamiltonian optics to the solutions of practical problems.Success has been sufficiently rare that the theory,as such,has made little direct contribution to techniques for optical instrument design.The failures have been frustrating because of the obvious fundamental p
21、ower of the theory and because of its conceptual elegance.The indirect effects have been large,however,both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other,more practical,theoretical approaches.Buchdah
22、l approaches the subject not only as a capable mathematical physicist,but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory.Buchdahls approach has,over the last decade,had a major impact on modern lens design with computers.Thus,he brin
23、gs to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical,and indeed it might be so viewed by a professional mathematician.From the point of view of many physicists and engineers,it w
24、ill appear to be quite mathematical.Moreover,this is a tightly written book.The subject matter is developed with precision,and the author expects the reader,at very point,to be master of the preceding exposition.8.Hamiltonian theory met with failures as a result of _.A.newer finding related to the w
25、ave particle nature of light B.very complicated concepts too difficult to understand by most lens designers C.too much mathematical detail in the theory D.not enough practical information offered by the theory to allow for use by lens crafters 9.The author of this passage implies that Introduction t
