ABooking a TheatreThese locations have theatres available for rental：*Fairview *Palmerston *York WoodsPriority BookingsEach June, theatre booking requests for dates in the following calendar year (January to December) are accepted. For more information, call the Room Booking Unit at 416-397-5969.Regular BookingsFor people who didn't make a booking request in June, call the Room Booking Unit at 416-397-5969 to check for remaining dates.Completing a BookingOnce the library receives a request, staff will check the availability and place a tentative booking for you. You will then receive a contract that you must return with payment within 10 calendar days of the tentative booking and with a minimum of two months before the first booking to confirm the booking. PaymentPayment for the first booking and any bookings in the current month is due when you return the signed contract. If you have booked for multiple months, payments for those months are due at the21. What’s required if you want to make priority bookings?A. Calling the library first.B. Booking in previous June.C. Having a look at the theatre beforehand.D. Paying a visit to the Room Booking Unit.22. When should you make payments if you book a theatre in the current month?A. Ten days before the booking.B.When you make the booking.C. When you return the contract.D. At the beginning of the month.23.What’s the rate if a non-profit organization rents a theatre at Palmerston?A. $418.00/day.B. $209.00/day.C. $163/hr.D. $150.00／hr.BIn bringing up children, every parent watches eagerly the child’s acquisition (学会) of each new skill—— the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be firced to use a toilet too early. A young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child’s own happiness.As regards the development of moral standards in the growing child, consistency (一致性）is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that “example is better than precept”. If they are not sincere and do not practice what they say, their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.A sudden awareness of an obvious d ifference between their parents’ principles and their morals can bea dangerous disappointment.24. In the process of children’s learning new skills parents ________.A. should encourage them to read before they know the meaning of the words they readB. should not expect too much of themC. should achieve a balance between pushing them too hard and leaving them on their ownD. should create as many learning opportunities as possible25. The second paragraph mainly tells us that _________.A. parents should be strict with their childrenB. parental controls reflect only the needs of the parents and the values of the communityC. parental restrictions vary, and are not always enforced for the benefit of the children aloneD. parents vary in their strictness towards their children according to the situation26. The word “precept”(Line3, Para.3) probably means “_______”.A. ideasB. punishmentC. behaviorD. instructions27. In moral matters, parents should ________.A. observe the rules themselvesB. be aware of the marked difference between adults and childrenC. forbid things which have no foundation in moralityD. consistently ensure the security of their childrenCOnce, African lions were the kings of the jungle. But every day, they lose more and more of their home to humans. A new study done by Duke University shows that humans have taken over much of the lions habitat.Lions live on the African plains, which are called savannas. In the past 5 years, the number of people living on the Savannas African plains has grown rapidly. At the same time, the number of lions has dwindled quickly.The research team at Duke University used detailed pictures taken by satellite to carefully examine the African landscape. They were able to see very small farms and towns that are taking over the once-open plains. Lions need wide-open spaces to hunt. As the number of people and towns has increased, the African plains have become less welcoming to lions. The number of lions has dropped from about 100, 000 in 1960 to 32,000 today. West Africa has seen the largest drop ——fewer than 500 lions remain there.Researchers worry that the number of lions will decrease even more as the number of humans moving onto the savannas increases. People and lions living closely together have to compete for natural resources like water and food. Towns and farms that take over hunting grounds could force the lions out of those areas completely. Often, lions with no other sources of food will kill farm animals. Farmers will then kill the lions to protect their animals. African lions are also threatened by poachers, who hunt animals illegally. Many poachers hunt lions for sport or to take their fur.One of the authors of the Duke University study is conservationist Stuart Pimm. Pimm believes the group’s research can be helpful in planning ways for people and lions to share the African plains. One solution is to build higher fences to keep lions away from farm animals. African countries can also expand and better protect their wildlife reserves so that lions have safe places to hunt.28. The underlined word“dwindled”in Paragraph 2 can be best replaced by______________.A. grownB.changedC. doubledD. decreased29. According to the study done by Duke University,______________.A. there are 100, 000 lions on the African plainsB. African lions are losing their habitat to humansC. more and more people are moving out of AfricaD. the number of lions in West Africa has increased30. The following are solutions mentioned in the passage to protect lions EXCEPT________.A. expanding wildlife reservesB. avoiding conflict between lions and farmersC. preventing people from hunting lions illegallyD. stopping people from moving into the African plains31. Which of the following might be the best title for the passage?A. Losing African lionsB. Moving out of AfricaC. The kings of the jungleD. The problems of AfricaDSign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to explore how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar, is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of a teacher at Gallaudet University in Washington, D. C., the world’s only libe ral arts university for deaf people.When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something strange: among themselves, students signed differently from his classroom teacher.Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the“hand talk”his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on Earth? It was 1955, when even deaf people considered their signing as “substandard”. Stokoe’s idea was academic heresy (异端邪说).It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades, educators fought against his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. “What I said,”Stokoe explains, “is that language is not mouth stuff—it’s brain stuff.”32.What aroused the present growing interest in sign language?A. A famous scholar in the study of the human brain.B. A leading specialist in the study of liberal arts.C. An English teacher in a university for the deaf.D. Some senior experts in American Sign Language.33. According to Stokoe, sign language is ________.A. a substandard languageB. a genuine languageC. an artificial languageD. an international language34. Most educators objected to Stokoe’s idea because they thought ________.A. sign language was not widely used even by deaf peopleB. sign language was too artificial to be widely acceptedC. a language should be easy to use and understandD. a language could only exist in the form of speech sounds35. Stokoe’s argument is based on his belief that ________.A. sign language is as efficient as any other languageB. sign language originated from natural languageC. language is a system of meaningful codesD. language is a product of the brain第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项（选项中有两项为多余选项），并在答题卡上将该项涂黑。

【市级联考】广东省揭阳市2019届高三高考第一次模拟考试理综物理试题(解析版)
广东省揭阳市2019届高三上学期第一次模拟考试理科综合物理试题二、选择题：本题共8小题，每小题6分。
在每小题给出的四个选项中，第14～18题只有一项符合题目要求，第19～21题有多项符合题目要求。
全部选对的得6分，选对但不全的得3分，有选错的得0分。
1.如图所示，在粗糙水平面上放置A、B、C三个物块，物块之间由两根完全相同的轻弹簧相连接，两弹簧的伸长量相同，且它们之间的夹角∠ABC＝120°，整个系统处于静止状态。
已知A物块所受的摩擦力大小为f，则B物块所受的摩擦力大小为A. B. C. D.【答案】B【解析】试题分析：对A水平方向上受弹簧的拉力T和水平面的静摩擦力f作用，根据共点力平衡条件可知：T＝f，由于两根弹簧相同，且伸长量相同，因此，两弹簧上的弹力大小相等，对B，水平方向受两弹簧的拉力和水平面的静摩擦力f′作用，根据共点力平衡条件可知：f′＝2Tcos60°＝f，故选项B正确。
考点：本题主要考查了物体的受力分析、共点力平衡条件的应用问题，属于中档偏低题。
2.如图所示，边长为L的正方形有界匀强磁场ABCD，带电粒子从A点沿AB方向射人磁场，恰好从C点飞出磁场；若带电粒子以相同的速度从AD的中点P垂直AD射人磁场，从DC边的M点飞出磁场(M点未画出)。
设粒子从A点运动到C点所用时间为t1，由P点运动到M点所用时间为t2(带电粒子重力不计)，则t1 :t2为A. 1:1B. 2:3C. 3:2D.【解析】带电粒子从A点沿AB方向射人磁场，恰好从C点飞出磁场，可知粒子运动的半径为L,在磁场中运动转过的角度为900；若带电粒子以相同的速度从AD的中点P垂直AD射入磁场，则运动半径仍为L，由几何关系可知，从DC边的M点飞出磁场时在磁场中转过的角度为600；粒子在磁场中的周期不变，根据可知t1 :t2=900:600=3:2，故选C.3.如图所示，x为未知的放射源，L为薄铝片，若在放射源和计数器之间加上L后，计数器的计数率大幅度减小，在L和计数器之间再加竖直向下的匀强磁场，计数器的计数率不变，则x可能是A. α射线和β射线的混合放射源B. 纯α射线放射源C. 纯γ射线放射源D. α射线和γ射线的混合放射源【答案】D【解析】【详解】在放射源和计数器之间加薄铝片L后，发现计数器的计数率大幅度减小，说明射线中含有穿透能力弱的粒子，在L和计数器之间再加竖直向下的匀强磁场B，计数器的计数率不变，说明剩下的粒子不带电，即为γ射线，因此放射源x可能是α和γ的混合放射源，故ABC错误，D正确。

ABooking a TheatreThese locations have theatres available for rental：*Fairview *Palmerston *York WoodsPriority BookingsEach June, theatre booking requests for dates in the following calendar year (January to December) are accepted. For more information, call the Room Booking Unit at 416-397-5969. Regular BookingsFor people who didn't make a booking request in June, call the Room Booking Unit at 416-397-5969 to check for remaining dates.Completing a BookingOnce the library receives a request, staff will check the availability and place a tentative booking for you. You will then receive a contract that you must return with payment within 10 calendar days of the tentative booking and with a minimum of two months before the first booking to confirm the booking.PaymentPayment for the first booking and any bookings in the current month is due when you return the signed contract. If you have booked for multiple months, payments for those months are due at21. What’s required if you want to make priority bookings?A. Calling the library first.B. Booking in previous June.C. Having a look at the theatre beforehand.D. Paying a visit to the Room Booking Unit.22. When should you make payments if you book a theatre in the current month?A. Ten days before the booking.B.When you make the booking.C. When you return the contract.D. At the beginning of the month.23.What’s the rate if a non-profit organization rents a theatre at Palmerston?A. $418.00/day.B. $209.00/day.C. $163/hr.D. $150.00／hr.BIn bringing up children, every parent watches eagerly the child’s acquisition (学会) of each new skill—— the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be firced to use a toilet too early. A young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child’s own happiness.As regards the development of moral standards in the growing child, consistency (一致性）is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that “example is better than precept”. If they are not sincere and do not practice what they say, their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.A sudden awareness of an obvious difference between their parents’ principles and their morals can be a dangerous disappointment.24. In the process of children’s learning new skills parents ________.A. should encourage them to read before they know the meaning of the words they readB. should not expect too much of themC. should achieve a balance between pushing them too hard and leaving them on their ownD. should create as many learning opportunities as possible25. The second paragraph mainly tells us that _________.A. parents should be strict with their childrenB. parental controls reflect only the needs of the parents and the values of the communityC. parental restrictions vary, and are not always enforced for the benefit of the children aloneD. parents vary in their strictness towards their children according to the situation26. The word “precept”(Line3, Para.3) probably means “_______”.A. ideasB. punishmentC. behaviorD. instructions27. In moral matters, parents should ________.A. observe the rules themselvesB. be aware of the marked difference between adults and childrenC. forbid things which have no foundation in moralityD. consistently ensure the security of their childrenCOnce, African lions were the kings of the jungle. But every day, they lose more and more of their home to humans. A new study done by Duke University shows that humans have taken over much of the lions habitat.Lions live on the African plains, which are called savannas. In the past 5 years, the number of people living on the Savannas African plains has grown rapidly. At the same time, the number of lions has dwindled quickly.The research team at Duke University used detailed pictures taken by satellite to carefully examine the African landscape. They were able to see very small farms and towns that are taking over the once-open plains. Lions need wide-open spaces to hunt. As the number of people and towns has increased, the African plains have become less welcoming to lions. The number of lions has dropped from about 100, 000 in 1960 to 32,000 today. West Africa has seen the largest drop ——fewer than 500 lions remain there.Researchers worry that the number of lions will decrease even more as the number of humans moving onto the savannas increases. People and lions living closely together have to compete for natural resources like water and food. Towns and farms that take over hunting grounds could force the lions out of those areas completely. Often, lions with no other sources of food will kill farm animals. Farmers will then kill the lions to protect their animals. African lions are also threatened by poachers, who hunt animals illegally. Many poachers hunt lions for sport or to take their fur.One of the authors of the Duke University study is conservationist Stuart Pimm. Pimm believes the group’s research can be helpful in planning ways for people and lions to share the African plains. One solution is to build higher fences to keep lions away from farm animals. African countries can also expand and better protect their wildlife reserves so that lions have safe places to hunt.28. The underlined word“dwindled”in Paragraph 2 can be best replaced by______________.A. grownB.changedC. doubledD. decreased29. According to the study done by Duke University,______________.A. there are 100, 000 lions on the African plainsB. African lions are losing their habitat to humansC. more and more people are moving out of AfricaD. the number of lions in West Africa has increased30. The following are solutions mentioned in the passage to protect lions EXCEPT________.A. expanding wildlife reservesB. avoiding conflict between lions and farmersC. preventing people from hunting lions illegallyD. stopping people from moving into the African plains31. Which of the following might be the best title for the passage?A. Losing African lionsB. Moving out of AfricaC. The kings of the jungleD. The problems of AfricaDSign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to explore how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar, is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of a teacher at Gallaudet University in Washington, D. C., the world’s only liberal arts university for deaf people.When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something strange: among themselves, students signed differently from his classroom teacher.Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the“hand talk”his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on Earth? It was 1955, when even deaf people considered their signing as “substandard”. Stokoe’s idea was academic heresy (异端邪说).It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades, educators fought against his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. “What I said,”Stokoe explains, “is that language is not mouth stuff—it’s brain stuff.”32.What aroused the present growing interest in sign language?A. A famous scholar in the study of the human brain.B. A leading specialist in the study of liberal arts.C. An English teacher in a university for the deaf.D. Some senior experts in American Sign Language.33. According to Stokoe, sign language is ________.A. a substandard languageB. a genuine languageC. an artificial languageD. an international language34. Most educators objected to Stokoe’s idea because they thought ________.A. sign language was not widely used even by deaf peopleB. sign language was too artificial to be widely acceptedC. a language should be easy to use and understandD. a language could only exist in the form of speech sounds35. Stokoe’s argument is based on his belief that ________.A. sign language is as efficient as any other languageB. sign language originated from natural languageC. language is a system of meaningful codesD. language is a product of the brain第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项（选项中有两项为多余选项），并在答题卡上将该项涂黑。
