第Ⅰ卷
第一部分阅读理解（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，从每题所给的四个选项（A、B、C、和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
Melbourne, Australia
Melbourne is a hotspot travel destination, and it’s easy to see its beautiful beaches and busy city life.
Wh y it’s a great choice: Australia as a whole is considered a safe destination for international travel, and because of that, many solo travelers go there. As an English-speaking country, you won’t be faced with any language barriers. Melbourne is easy to ge t around because you can walk or bike practically anywhere!
Thailand
Thailand is great for solo travelers —perhaps because it is one of the Buddhist mindsets, which promote equality among the sexes.
Why it’s a great choice: Thailand is known for its frien dly atmosphere, and as a travel hotspot, there are plenty of chances to meet other like-minded travelers. Well known for being very cheap, especially in the north. A good choice if you want to get away on a budget. Thailand has a lot to offer, from the party- central Bangkok to beautiful beaches and tropical (热带的) jungle.
Hong Kong, China
Hong Kong is a great place to relax for solo travelers as it is full of “Zen Moments”, such as beautiful gardens and Tai Chi classes.
Why it’s a great choice: Hong Kong is regarded as one of the safest cities in the world. If you’re not well traveled, or perhaps a bit tired of things like language barriers, Hong Kong is a great place to start, as it mixes both Eastern and Western at the same time.
Bali, Indonesia
Bali is a spiritual place with yoga, spas, healthy food and beaches. The combination of friendly people and splendid visual culture has made Bali number one tourist attraction.
Why it’s so great: you won’t be the only solo traveler in Bali. Everyone is known for being extremely friendly and you’re sure to meet some amaz ing characters along the way. As a Hindu island, Bali is the perfect place for a relaxing and spiritual retreat (静修). The Sacred Monkey Foresting Ubud is fantastic 一if you like monkeys, anyway.
21. What do the four places have in common according to the text?
A. They’re cheap to travel around.
B. They’re great for solo travelers.
C. They offer good spas and yoga.
D. There’re no language barriers.
22. Where can you enjoy both convenient transport and beautiful beaches?
A. Melbourne, Australia.
B. Thailand.
C. Hong Kong, China.
D. Bali, Indonesia.
23. What has made Bali No.1 tourist attraction?
A. Yoga, spas, healthy food and beaches.
B. Friendly people and splendid visual culture.
C. Meeting some amazing characters along the way.
D. Fantastic monkeys in the Sacred Monkey Forest.
24. What type of writing is this text?
A. A travel journal.
B. A business report.
C. A travel guide.
D. A press advertisement.
B
I log onto a computer at the doctor’s office to say I have arrived and then wait un til a voice calls me into the examination room.
There, a robotic nurse directs me onto a device and then takes my blood pressure. Some time later, in steps the doctor, who is also a robot. He notes down my symptoms and gives me a prescription (处方). I pay for my visit using a credit card machine and return home without having met another human being.
When I call my dentist’s office and actually get a human being on the line, I am thrilled. And when I see the introduction of yet more self-service checkout stations at the grocery store, I feel like shouting, “When it comes to cashiers, make mine human, please!”
After all, human cashiers sometimes give you a store coupon (优惠券) for items you are buying. Even more than that, real-life cashiers often take an interest in particularly cute children, which can brighten a young mother’s day. A cashier may also show compassion (同情) for an elderly person struggling to get that last penny out of her purse.
What technological device would do any of this? I don’t want to go back to the Stone Age, but I’m also worried about a world run by machines. Sometimes when you’re chatting with someone, you discover things you need to know. Maybe a receptionist needs prayers said for a sick child. Maybe a salesperson can offer a bit of encouragement to a customer who is feeling tired.
Machines can be efficient and cost-effective and they often get the job done just fine. But they lack an element so important to everyday life.
Call it the spirit, the soul or the heart. It is something no machine will ever have. It is being human that prompts us to smile at others, which may be what they need at that moment.
25. What’s the author’s purpose in writing the first two paragraphs?
A. To indicate high technology can make our future life very easy.
B. To describe a possible future scene where robots take control of our life.
C. To warn readers of the possible dangers of robotic nurses and doctors.
D. To predict how technology can affect the way we see a doctoring the future.
26. Why does the author prefer being served by humans rather than by robots?
A. Robots are indifferent and emotionless.
B. Robots can’t provide efficient services.
C. Robots don’t offer to give store coupons.
D. Robots are unable to do a job as well as humans.
27. Wha t’s the author’s attitude towards machines?
A. He wishes one day they would come to life.
B. He is absolutely against their existence in his life.
C. He doesn’t like they get involved in his life too much.
D. He is afraid they would take the place of human beings.
C
Are you content with the shape of your nose? If not, the climate may be to blame, not your
parents.
This is according to a recent study carried out by scientists from Pennsylvania State University, US. They found that climate played a key role in shaping our noses. The findings were based on an examination of the size and shape of noses of 476 people from four regions---West Africa, East Asia, South Asia and Northern Europe, using 3-D facial imaging technology.
“People have thought for a long tim e the difference in nose shape among humans across the world may have arisen as a result of natural selection because of climate,” Arslan Zaidi, one of the lead authors of the study, told The Guardian. But while previous studies were based on measurements from human skulls, Zaidi and his team looked at nose shape itself.
The result showed that wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates. That, Zaidi said, could be because narrower nasal passages help to increase the moisture (潮湿) content of air and warm it，which is easier on our lungs. This, in turn, led to a gradual decrease in nose width in populations living far away from the equator.
More study is still needed to test the link between climate and nose shape, but Zaidi believes the current findings are valuable in understanding potential health issue. “As we become more of a global community, we are going to come across climates that we are not adapt to,” he told the Guardian. This means moving to a very different climate might increase the risk of breathing problems.
However, he added, “This may not be necessarily true for various reasons such as of modern medicine and the fact that our current climate is very different from what it used to be.”
28. From the passage we know most people from Singapore have ________ noses.
A. wider
B. narrower
C. smaller
D. larger
29. Narrower noses are helpful to ________.
A. cool the air
B. warm the air
C. take in more oxygen
D. dry the air
30. What can be learned about the study?
A. Zaidi’s team measured human skull using 3-D technology.
B. Shapes of our noses are determined by our parents.
C. Nose shape helps people adapt to the environment.
D. It’s certain that people will suffer from more b reathing problems.
31. Which of the following can be the best title of the passage?
A. What factors shape noses?
B. How to make your nose attractive?
C. Nose shapes cause breathing problems
D. Climate shapes noses
D
Robot Surgeon (外科医生) Succeeds without Help from Human Doctors Humans make mistakes. Even surgeons with years of experience are not infallible. But what if these doctors could pool their knowledge and experience together and create a surgical standard of care, to be carried out by machines?
That’s the idea behind surgical robots, which may soon perform most surgeries, from sewing up tiny wounds to performing heart procedures. Many of these operations are, in fact, already completed with the assistance of robots. But a recent test suggests that robots in the operating room may soon go a step further, performing on soft tissue completely on their own, from start to finish.
The Smart Tissue Autonomous Robot (STAR), successfully completed surgeries on pigs. “We're the first group t o develop autonomous robotic surgery with soft﹣tissue surgery, and when compared to standard operation, it's better, "says Peter Kim, professor of surgery.” The idea is not to replace surgeons; it will make the surgeons better and make the procedures safer.”
A recent Mayo Clinic study found that major surgical errors﹣including operating on the wrong site or side of the body, or even leaving tools or objects inside the patient﹣occur every one out of 22, 000procedures. That's rare, but robots like STAR would aim to lower the number even further.
In the da Vinci surgical system, surgeons place their arms inside instruments and use their hands to control the movement of robotic tools on the operating table from afar. The robot's every major move is controlled by surgeons, and thus its results may vary based on the surgeon's training or experience.
STAR, on the other hand, is entirely autonomous. It's not only able to work on its own and perform surgeries with a more flexible “hand”, but it's able to react to the unexpected incidents. Cutting into hard tissue like bones is one thing, but operating on moving soft tissue is far more
complex. STAR reacts to a changing environment, similar to how self﹣driving cars are programmed to not only drive on the highway, but also react to another driver making a mistake and getting in your way.
32. The underlined word “infallible” in Paragraph 1probably means ________.
A. always right
B. really creative
C. rather responsible
D. quite smart
33. We can learn from the passage that STAR ________.
A. has been widely used in the operating room
B. can perform the operation on its own
C. can make surgeries much faster
D. will take the place of surgeons
34. In the da Vinci surgical system, ________.
A. robots are trained from afar
B. surgery results depend on surgeons
C. robots always make mistakes
D. surgeons have trouble controlling robots
35. In the last paragraph, the author mentions self﹣driving cars in order to show ________.
A. how bad getting in another driver's way might be
B. how difficult self﹣driving on the highway is
C. how smart an autonomous robot can be
D. how dangerous operating on people is.

2. Do the following things.
First you need to notice the title above each section. That will tell you what the section is about. _38_. Read the first and last sentences of each paragraph slowly and carefully and re-read them if you have to.
3. Familiarize yourself with the material.
_39_. So for a job, you might search online for something similar to what you are reading. For students, school websites are useful or another textbook may be able to explain words in a way that is easier to understand,
4. Review the material
After you have read and understood the material, review it a few times a day, _40_. Studies have shown that on average it takes several (anywhere from 3 to 8) times reading and reviewing a material before it becomes part of your permanent memory.
A. It can be very helpful to refer to extra material.
B. It can be hard to read something and keep it in mind.
C. It is easier to remember concepts when you rewrite them.
D. Also, topic sentences are valuable sources of information.
E. If everything is important, you wilt have to work a little harder.
F. This will help you understand it better and remember the information.

Mother’s Day is around the corner, and to mark the occasion, I want to share with you what Mom taught me, impressed upon me, and how she otherwise shaped me.
From my earliest _41_, I felt as if my mother was preparing me for _42_ special. When we entered a room, her entire focus was on me. I felt as if I was the _43_ of her universe — a great feeling. Offering her the same _44_, I intently listened to her stories without _45_. I tried to return that feeling of being truly loved.
_46_ there was always deep affection flowing between us, she wasn’t a softy (心肠软的人). She worked hard and _47_ her children to do the same. I began working in our little corner grocery store by age eight and _48_ it by the age of twelve. She _49_ my hard work and treated me as an equal. I learned that I could do anything through hard work. I learned _50_.
Mom always supported my decisions, but also _51_ her concern. When I decided to retire
early from teaching to writing about etiquette (礼仪), she announced her concern. She _52_ that there wasn’t a _53_ for it —my mom, always the business person. _54_, by the end of our conversation she _55_ me with, “With your training and love of people, you are _56_ for this.” She followed quickly with a saying I’ll always remember, “Nothing is _57 to a man who will have a try.” Thanks, Mom.
By _58_, my mother taught me how to show respect for others. She gave me my listening skills, my courage, and my manners. Through her, I _59_ to be strong, to follow my heart, and to work hard. I never _60_. If not for this, I wouldn’t be a successful business owner and good friend to all.

Michael loves scuba-diving (斯库巴潜水).
By 9, he was an extraordinary swimmer and a good listener in the pool.
Michael’s first dive, _61_, was truly unforgettable. Instead of using a boat, the plan was to go down a ladder at the boat and drop into about 15 feet of water. Everything went perfectly. His inst ructor Polly led him to the nearby reef. While _62_ (explore) the reef in 27 feet of water, Michael suddenly signaled a problem with his mask. Polly signaled back for him to clear it. He cleared it _ 63_ then later signaled the problem again. His mask was completely flooded _64_ water. Michael made a sign _65_ he wanted to go up. Polly signaled, “NO! Stay with me!”
According to Polly, even though scuba _66_ (train) teaches new divers how to deal with floo ded masks, many beginners panic the first time water fills their masks during an actual dive. Mich ael wasn’t like many beginners, though. He didn’t panic. He did _67_ (exact) what he learned to d o during his years. He stayed calm, _68_ (think) it through, and followed Polly’s _69_ (instruct). P olly gradually led Michael to shallower water in an area. The group swam together back to the sho re for a celebration of Michael’s _70_ (amaze) accomplishment.

2019年佛山一中自主招生语文试题。 老圣人 赵长春 （1）袁店河有个说法：人读书多了，读得出不来了，就叫“圣人”。这个说法有点讽刺和嘲弄。 （2）老圣人也被称作“圣人”，当年，他被唤作“圣人”，原因不得而知。现在老了就加了个定语，“老圣人”。 （3）老圣人做的事情有些不同于他人。就拿春分这—天来说，他要把村里的小孩子们召集起来，在村中老槐树下的大碾盘上，立蛋。（4）立蛋，就是春分这一天，将鸡蛋立起来。老圣人先示范，轻手撮一鸡蛋，竖在平展的碾盘上，屏息，慢慢松开，鸡蛋就立起来了！然后，他给孩子们分鸡蛋，一人两枚，围绕碾盘，看谁先立起来，发奖。 （5）这个时候，是村子里春节过后的又一次小热闹。不过，大人们不多，年轻人更少，这时候，老圣人看着孩子们，一脸的笑。 （6）人们说:“这有啥意思？自己买鸡蛋，再买些铅笔、写字本文具盒……”老圣人说：“这很有意思。就拿春分立蛋来说，是老祖宗们四千多年前就玩的游戏，一辈辈、一袋袋，传到现在了，会玩的人少了，人家外国反而玩疯……”老圣人说：“一年之计在于春，让孩子们立鸡蛋，心静一下，比玩游戏好。” （7）说话间，已经有好几个孩子将鸡蛋立起来了。孩子们很开心地围拢着老圣人，听他讲春分，讲节气，讲碾盘的故事。 （8）碾盘也有故事，碾盘很老了，村里人用了好多年，如同村口的老井。现在，条件好了，人们不用碾盘了，包括石磙，还有老井。老井早就被填埋了，一些石磨、石磙，还有马槽，莫名其妙地消失了。后来，人们才知道，被人偷跑了，卖到城里了……老圣人就操心老槐树下的大碾盘。有个夜晚，老圣人突然喊了起来，就在老槐树下。原来，那些人又来偷了！ （9）老圣人说，每个人都有故事，每个村子都有历史，每一家都是传奇。这老碾盘，每家的祖辈都吃过它碾出的面、小米、苞谷……他说的故事，有个后来上了大学的孩子写了出来，写进了他的书里。老

2018-2019学年度揭阳第一中学高一第一学期期末考试 物理试卷 一、选择题 1.下列说法正确的是（） A. 研究奥运会冠军刘翔的跨栏技术时可将刘翔看作质点 B. 电台报时说：“现在是北京时间8点整”，这里的“时间”实际上指的是时刻 C. 加速度为0的物体一定处于静止状态 D. 做直线运动的物体当加速度方向与速度方向相同时，若加速度减小，速度也减小 【答案】B 【解析】 【详解】A、研究奥运会冠军刘翔的跨栏技术时，要看刘翔的动作，不能看成质点，故A错误；B、时刻是时间轴上的点，而时间是时间轴上的一段长度，“现在是北京时间8点整”，这里的“时间”实际上是一个点，指的是时刻，故B正确； C、加速度为零的物体不一定处于静止状态，可能做匀速直线运动，故C错误； D、做直线运动的物体当加速度方向与速度方向相同时，物体速度增大，加速度减小，只是速度增的慢，但速度仍然在增大，故D错误。 【点睛】考查的知识点比较多，考查了质点、时间与时刻，加速度等，需要掌握各个知识的概念，理解其规律。 2.如图是A、B两质点从同一地点同向运动的x-t图像，则下列说法正确的是（） A. A、B两质点在4 s时相遇 B. 0-4s，两质点走过的路程不相等 C. B质点0-8 s内x≥0，故其运动方向一直不变 D. 0-4 s，A的速度一直小于B的速度 【答案】A 【解析】 【分析】
x-t图象的斜率表示物体运动的速度，根据斜率的变化分析物体的运动情况，两图象相交时表示相遇，速度的正负表示质点的运动方向； 【详解】A、A、B两质点在4s时位移相等，则两质点相遇，故A正确； B、由图可知，在0-4s，两质点均沿正方向运动，走过的路程相等，都是80m，故B错误； C、x-t图象的斜率等于速度，可知B质点在0-8s内速度先为正后为负，故其运动方向发生了变化，故C错误； D、因x-t图象的斜率等于速度，则在0-4s内，B的速度的大小先大于A的速度的大小，某时刻A、B速度相等，然后B的速度大小小于A的速度的大小，故D错误。 【点睛】解决本题的关键是知道x-t图象的斜率表示速度，x-t图象可以明确看出位移的变化和位置关系。 3.下列各实例中力的方向描述正确的是（） A. 图甲中，碗对筷子的弹力 B. 图乙中，篮球与地面作用时，地面对篮球的弹力 C. 图丙中，物体A与传送带一起匀速向右行驶，传送带对A的摩擦力 D. 图丁中，物体A上滑时，斜面对A的摩擦力 【答案】B 【解析】 【分析】 物体受到的弹力是由于施力物体由于恢复形变而产生的，其方向与接触面垂直，摩擦力的方向与二者相对运动的方向相反； 【详解】A、图甲中，圆弧对杆的弹力的方向指向半圆形碗的圆心，故A错误； B、图乙中，篮球与地面作用时，地面对篮球的弹力垂直接触面竖直向上，故B正确； C、图丙中，物体A与传送带一起匀速向右行驶，传送带对A没有摩擦力作用，故C错误； D、图丁中，物体A上滑时，斜面对A的摩擦力方向与二者相对运动的方向相反，即A受到的摩擦力方向为平行斜面向下，故D错误。 【点睛】对于弹力要注意理解弹力产生的原因，这样有助于理解掌握弹力的方向，同时要注意摩擦力的方向的判断问题。
