Joseph Frederick Engelberger, the Father of Robotics, was born on July 26, 1925.He received his degree in Electric Engineering in 1949 from Columbia University.He worked as an engineer in a company and then he met George Devol at a party in 1956, two years after Devol had designed and patented (获得专利权) an industrial robotic arm.However, the company where Engelberger worked was closed in the year he met Devol.
Finding himself jobless but with a business partner and an idea, Engelberger co-founded Unimation with Devol, creating the world's first robotics company.Over the next two decades, the Japanese took the lead by investing (投资) heavily in robots to replace people performing certain tasks.In Japan, Engelberger was widely recognized as a key player in Japanese manufacturing quality and efficiency.
After observing his aging parents, Engelberger saw the robotics automation could be used in the medical field.In 1984, Engelberger introduced HelpMate and hoped to start a new industry for in-home robots.He sold his first HelpMate to Danbury Hospital in 1988.The medical robot was so successful that the hospital ended up purchasing another, and within a decade, well over 100 hospitals worldwide operated HelpMates.
Senator Joseph Lieberman delivered a speech in the U．S.Senate in praise and recognition of the inventor, calling HelpMate an example that shows the federal investment in science and technology for patients can lead to new products that create jobs for Americans and make for a better quality of life.
Engelberger liked working.So even after he got into his 80s, he remained active in the promotion and development of robots for use in elder care.
4．What can be learned about Engelberger
A．He lost his job in 1956.
B．He invented a robotic arm in 1958.
C．He got his college degree in 1925.
D．His company had been shut down before he met Devol.
5．Why did Engelberger invent HelpMate
A．To satisfy the need of hospitals.
B．To better help his parents out.
C．To start a new industry for in-home robots.
D．To take the place of people in medical field.

A．Uncaring. B．Disagreeable.
C．Approval. D．Doubtful.
7．Which of the following words can best describe Engelberger
A．Sincere and kind. B．Persistent and innovative.
C．Ambitious and selfless. D．Inspiring and peace-loving.
C
Do you have imagination Do you like to solve problems If so, you could be the next great inventor.“But_I'm_just_a_kid，” you might be! Don't worry about a little thing like age.For example, one famous inventor, Benjamin Franklin, got his start when he was only 12.At that young age, he created paddles for his hands to help him swim faster.Finally his creation led to what we know as flippers!
So you don't have to be adult to be an inventor.One thing you do need, though, is something that kids have plenty of: curiosity and imagination.Kids are known for looking at things in new and unique ways.
So what should you do if you have what is a great idea for an invention Talk to a friend or family member about it.Get input from others about your idea.Then ask them to help you create a working model — called a prototype (原型) of your idea.
Once you have a prototype, you can test it.Sometimes your idea turns out to be not as great as you thought.At other times, though, you realize it is a good idea and your prototype can help you figure out how to make it even better.
If your idea is really a good one, an adult can help you contact companies that might be interested in it.You will also want an adult's help to get a patent for your idea, so that it is protected and can't be stolen by someone else.If you need some inspiration, consider these kids and their inventions.
Jeanie Low invented the Kiddie Stool when she was just 11.It's a folding stool that fits under the kitchen sink.Kids can unfold it and use it to reach the sink all by themselves.
At the age of 15, Louis Braille invented the system named after him that allows the blind to read.
Chelsea Lanmon received a patent when she was just 8 for the “pocket diaper (尿布)”， a new type of diaper that includes a pocket for holding baby wipes and powder.
8．By saying “But I'm just a kid”， you probably mean you ________.
A．are too young to achieve anything
B．can do anything though you are young
C．are old enough to become an inventor
D．have to learn something from other people
9．Kids are most likely to be inventors probably because they ________.
A．would like to make friends with others
B．usually work hard at their lessons at school
C．like playing all kinds of toys at home
D．think about things in quite different ways
10．Who invented something that helps the blind to read
A．Jeanie Low. B．Benjamin Franklin.
C．Chelsea Lanmon. D．Louis Braille.
11．Which of the following can be the main idea of this text
A．Kids have curiosity and imagination.
B．There are some world-famous inventors.
C．It is possible for kids to be inventors.
D．Kids are exactly like adults in a way.
D
WHAT are scientists They are often described as gray-haired white-coated dull scholars.
But the world has changed.Young scientists are making their voices heard and releasing their powers on the world stage.
This is also true in China.Rising stars include new materials expert Gong Yongji, university professor Liu Mingzhen, and biologist Wang Ruixue.At the age of 28 in 2018, Wang Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists.This is a global prize to reward outstanding scientists at an early stage of their careers.
She focuses mainly on biomedicine (生物医学) and artificial intelligence.“Both are cutting-edge (前沿的) technologies at an early stage of development，” she said.
“So, I think they have great potential to be developed.I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line.And in the study of structural biology, China is likely to become the leader.”
She felt it was her fate to become a biologist.“I grew interested in the natural world, when I was very young，” she said.In 2009, she entered Sun Yat-sen University.
In her third year at the university, she realized that she wanted to do something related to biomedicine.So she emailed China's top biologist Shi Yigong, hoping to join his lab at Tsinghua University.
Shi recognized her talent and welcomed her.Years of efforts at the lab have paid off.Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.
Unlike many of other young scientists who choose to pursue further study abroad, Wang currently has no plan to go overseas.
“The whole ecosystem for scientific research is continually improving in China，” she said, adding the country has great science facilities.
12．What does the underlined word “releasing” in paragraph 2 mean
A．Giving out. B．Getting over.
C．Finding out. D．Taking over.
13．What does Wang Ruixue feel about the study of cutting-edge technologies in China
A．Anxious. B．Confident.
C．Disappointed. D．Satisfied.
14．What can we learn about Wang Ruixue's journey of becoming a biologist
A．Her teacher led her into the field.
B．She finds it's easier than she thought.
C．Her contribution has been recognized.
D．She thinks it's boring but worth trying.
15．Which can be the best title of the text
A．China's Breakthrough in Science
B．Rising Young Scientists in China
C．Wang Ruixue: A Successful Young Scientist
D．New Image of Chinese Scientists
第二节(共5小题；每小题2.5分，满分12.5分)
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
Around 200 years ago, a well-known English poet called John Keats attacked science. He said that British scientist Isaac Newton had “unweaved (拆解) the rainbow”. Newton explained how light forms a rainbow. For Keats, this explanation meant rainbows could no longer be beautiful.
__16__ We often hear people talk of problems with science, or say that it is boring. Some people, like Keats, also say that science takes away the beauty of the world. But is this fair
First of all, science helps us get things done. __17__ When you are studying science in school, remember that one day you might be using that knowledge to build a bridge, or save a life. Next time you use your phone to send a message, but remember that this is possible thanks to science. When Keats criticized Newton, the very paper he wrote on was created through science. Beyond helping society and getting things done, science also makes us think in a certain way. __18__ It teaches us never to trust our assumptions. It teaches us that sometimes, the truth is stranger than fiction.
When you study science, remember what it means. __19__ Humans once looked up at rainbows, and said that they were beautiful. Science explained them, and they were no longer mysterious to us. __20__ Through science, we can find new rainbows: mysteries that lie beyond the stars themselves.
A．But discovery never stops.
B．This is just one example of many.
C．It asks us to believe things only through evidence.
D．Science is not so closely associated with our lives.
E．It is a constant search for truth and knowledge.
F．It helps us understand the world in which we live and how it works.
G．See science as a tool to discover how living things interact and evolve on Earth.

第二节(满分25分)
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Every night as the whole family fell asleep，Catalina would slide from home to the Cerro Tololo observatory (天文台)．Papa was the mechanic (修理工) of the observatory, but during the day Papa would not allow her to get closer to the telescopes there. Only at night, Catalina was allowed in with the permission of the night staff.
Catalina loved helping to service the grand telescopes, the eyes that look out into the universe. She wanted badly to be an astronomer someday. Adults never took her dream seriously. Even her father laughed，“Maybe you'll be hired to clean the offices.”
One day in library, Catalina was reading a plant journal when she stopped at the picture of an unusual white flower. “It's called wild carrot，” a Spanish astronomer, who she saw several times in the observatory, stood behind her. “Pretty, isn't it I've always liked that flower, because it looks like a galaxy.”
“A spiral galaxy (漩涡星系)，” she whispered. Blond eyebrows climbed the scientist's forehead. “Indeed. And what is your name, young lady？” he asked.
“I'm Catalina Solis.”
“Eduardo Solis's daughter The mechanic？”
“Yes，” She gave a look at him.“I want to be an astronomer when I grow up.”
He laughed kindly, no longer meeting her eyes，and patted her on the shoulder. “Yes, of course, my dear. Work hard in school, and it will happen.”
One evening, Catalina scanned the top of the observatory as usual. Suddenly she noticed the angle of the one-meter telescope was unusual. The telescope was pointed down, lower than she had ever seen it. Catalina learned from Papa how dangerous it would be. If left like it was, the telescope would move past its limit and be damaged. So without hesitation she got inside the observatory.
注意：1.续写词数应为150左右； 2.请按如下格式作答。
She saw the Spanish scientist buried in work there.
The scientist's words meant a lot to her.

Technology and Life
Hello, everyone!
Over the last few decades, new technologies have been constantly appearing, which has greatly changed our life.It is recognized that facial recognition makes it easier for us to get into stations, the airport and other places.Also, the high speed railway shortens the travelling time between two cities, enabling us to visit more places conveniently.In addition, mobile payment allows us to pay for everything wherever there is a QR code.
As is known to us, technologies are all around us.Obviously, they have made our life more efficient and colorful.Only by making better use of them can we become the master of life.
第二节(参考范文)
She saw the Spanish scientist buried in work there. Catalina walked gently towards the scientist, who happened to lift his head and noticed her.“Still want to know more about flowers, Catalina Solis？” Catalina shook her head and told the scientist her discovery about the telescope. Without any hesitation, the scientist stood up and approached the one meter telescope, observing, checking and adjusting the angle of it. A couple of minutes later，he spoke at last, “Thank you, young lady. What you found is quite timely and crucial. You are really a good candidate for an astronomer.”
The scientist's words meant a lot to her. She smiled so happily as it was the first time an adult had confirmed her dream.She made up her mind to run after her dream and nothing would stop her. The scientist invited her to work as an assistant, working with him.After years of hard work, Catalina, who had been equipped with abundant theory and practice, was admitted to an astronomy university. Her childhood dream finally became a reality. Nothing is impossible to a willing heart. However, to Catalina, it's the scientist's encouragement that pushed her so far.

Joseph Frederick Engelberger, the Father of Robotics, was born on July 26, 1925.He received his degree in Electric Engineering in 1949 from Columbia University.He worked as an engineer in a company and then he met George Devol at a party in 1956, two years after Devol had designed and patented (获得专利权) an industrial robotic arm.However, the company where Engelberger worked was closed in the year he met Devol.
Finding himself jobless but with a business partner and an idea, Engelberger co-founded Unimation with Devol, creating the world's first robotics company.Over the next two decades, the Japanese took the lead by investing (投资) heavily in robots to replace people performing certain tasks.In Japan, Engelberger was widely recognized as a key player in Japanese manufacturing quality and efficiency.
After observing his aging parents, Engelberger saw the robotics automation could be used in the medical field.In 1984, Engelberger introduced HelpMate and hoped to start a new industry for in-home robots.He sold his first HelpMate to Danbury Hospital in 1988.The medical robot was so successful that the hospital ended up purchasing another, and within a decade, well over 100 hospitals worldwide operated HelpMates.
Senator Joseph Lieberman delivered a speech in the U．S.Senate in praise and recognition of the inventor, calling HelpMate an example that shows the federal investment in science and technology for patients can lead to new products that create jobs for Americans and make for a better quality of life.
Engelberger liked working.So even after he got into his 80s, he remained active in the promotion and development of robots for use in elder care.

Do you have imagination Do you like to solve problems If so, you could be the next great inventor.“But_I'm_just_a_kid，” you might be! Don't worry about a little thing like age.For example, one famous inventor, Benjamin Franklin, got his start when he was only 12.At that young age, he created paddles for his hands to help him swim faster.Finally his creation led to what we know as flippers!
So you don't have to be adult to be an inventor.One thing you do need, though, is something that kids have plenty of: curiosity and imagination.Kids are known for looking at things in new and unique ways.
So what should you do if you have what is a great idea for an invention Talk to a friend or family member about it.Get input from others about your idea.Then ask them to help you create a working model — called a prototype (原型) of your idea.
Once you have a prototype, you can test it.Sometimes your idea turns out to be not as great as you thought.At other times, though, you realize it is a good idea and your prototype can help you figure out how to make it even better.
If your idea is really a good one, an adult can help you contact companies that might be interested in it.You will also want an adult's help to get a patent for your idea, so that it is protected and can't be stolen by someone else.If you need some inspiration, consider these kids and their inventions.
Jeanie Low invented the Kiddie Stool when she was just 11.It's a folding stool that fits under the kitchen sink.Kids can unfold it and use it to reach the sink all by themselves.
At the age of 15, Louis Braille invented the system named after him that allows the blind to read.
Chelsea Lanmon received a patent when she was just 8 for the “pocket diaper (尿布)”， a new type of diaper that includes a pocket for holding baby wipes and powder.
8．By saying “But I'm just a kid”， you probably mean you ________.
A．are too young to achieve anything
B．can do anything though you are young
C．are old enough to become an inventor
D．have to learn something from other people
9．Kids are most likely to be inventors probably because they ________.
A．would like to make friends with others
B．usually work hard at their lessons at school
C．like playing all kinds of toys at home
D．think about things in quite different ways
10．Who invented something that helps the blind to read

WHAT are scientists They are often described as gray-haired white-coated dull scholars.
But the world has changed.Young scientists are making their voices heard and releasing their powers on the world stage.
This is also true in China.Rising stars include new materials expert Gong Yongji, university professor Liu Mingzhen, and biologist Wang Ruixue.At the age of 28 in 2018, Wang Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists.This is a global prize to reward outstanding scientists at an early stage of their careers.
She focuses mainly on biomedicine (生物医学) and artificial intelligence.“Both are cutting-edge (前沿的) technologies at an early stage of development，” she said.
“So, I think they have great potential to be developed.I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line.And in the study of structural biology, China is likely to become the leader.”
She felt it was her fate to become a biologist.“I grew interested in the natural world, when I was very young，” she said.In 2009, she entered Sun Yat-sen University.
In her third year at the university, she realized that she wanted to do something related to biomedicine.So she emailed China's top biologist Shi Yigong, hoping to join his lab at Tsinghua University.
Shi recognized her talent and welcomed her.Years of efforts at the lab have paid off.Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.
Unlike many of other young scientists who choose to pursue further study abroad, Wang currently has no plan to go overseas.
“The whole ecosystem for scientific research is continually improving in China，” she said, adding the country has great science facilities.
12．What does the underlined word “releasing” in paragraph 2 mean
A．Giving out. B．Getting over.
C．Finding out. D．Taking over.
13．What does Wang Ruixue feel about the study of cutting-edge technologies in China
A．Anxious. B．Confident.
C．Disappointed. D．Satisfied.
14．What can we learn about Wang Ruixue's journey of becoming a biologist
A．Her teacher led her into the field.
B．She finds it's easier than she thought.
C．Her contribution has been recognized.
D．She thinks it's boring but worth trying.
15．Which can be the best title of the text
A．China's Breakthrough in Science
B．Rising Young Scientists in China
C．Wang Ruixue: A Successful Young Scientist

Around 200 years ago, a well-known English poet called John Keats attacked science. He said that British scientist Isaac Newton had “unweaved (拆解) the rainbow”. Newton explained how light forms a rainbow. For Keats, this explanation meant rainbows could no longer be beautiful.
__16__ We often hear people talk of problems with science, or say that it is boring. Some people, like Keats, also say that science takes away the beauty of the world. But is this fair
First of all, science helps us get things done. __17__ When you are studying science in school, remember that one day you might be using that knowledge to build a bridge, or save a life. Next time you use your phone to send a message, but remember that this is possible thanks to science. When Keats criticized Newton, the very paper he wrote on was created through science. Beyond helping society and getting things done, science also makes us think in a certain way. __18__ It teaches us never to trust our assumptions. It teaches us that sometimes, the truth is stranger than fiction.
When you study science, remember what it means. __19__ Humans once looked up at rainbows, and said that they were beautiful. Science explained them, and they were no longer mysterious to us. __20__ Through science, we can find new rainbows: mysteries that lie beyond the stars themselves.
A．But discovery never stops.
B．This is just one example of many.
C．It asks us to believe things only through evidence.
D．Science is not so closely associated with our lives.
E．It is a constant search for truth and knowledge.
F．It helps us understand the world in which we live and how it works.
G．See science as a tool to discover how living things interact and evolve on Earth.

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Every night as the whole family fell asleep，Catalina would slide from home to the Cerro Tololo observatory (天文台)．Papa was the mechanic (修理工) of the observatory, but during the day Papa would not allow her to get closer to the telescopes there. Only at night, Catalina was allowed in with the permission of the night staff.
Catalina loved helping to service the grand telescopes, the eyes that look out into the universe. She wanted badly to be an astronomer someday. Adults never took her dream seriously. Even her father laughed，“Maybe you'll be hired to clean the offices.”
One day in library, Catalina was reading a plant journal when she stopped at the picture of an unusual white flower. “It's called wild carrot，” a Spanish astronomer, who she saw several times in the observatory, stood behind her. “Pretty, isn't it I've always liked that flower, because it looks like a galaxy.”
“A spiral galaxy (漩涡星系)，” she whispered. Blond eyebrows climbed the scientist's forehead. “Indeed. And what is your name, young lady？” he asked.
“I'm Catalina Solis.”
“Eduardo Solis's daughter The mechanic？”
“Yes，” She gave a look at him.“I want to be an astronomer when I grow up.”
He laughed kindly, no longer meeting her eyes，and patted her on the shoulder. “Yes, of course, my dear. Work hard in school, and it will happen.”
One evening, Catalina scanned the top of the observatory as usual. Suddenly she noticed the angle of the one-meter telescope was unusual. The telescope was pointed down, lower than she had ever seen it. Catalina learned from Papa how dangerous it would be. If left like it was, the telescope would move past its limit and be damaged. So without hesitation she got inside the observatory.
注意：1.续写词数应为150左右； 2.请按如下格式作答。
She saw the Spanish scientist buried in work there.
The scientist's words meant a lot to her.

第二节(参考范文)
She saw the Spanish scientist buried in work there. Catalina walked gently towards the scientist, who happened to lift his head and noticed her.“Still want to know more about flowers, Catalina Solis？” Catalina shook her head and told the scientist her discovery about the telescope. Without any hesitation, the scientist stood up and approached the one meter telescope, observing, checking and adjusting the angle of it. A couple of minutes later，he spoke at last, “Thank you, young lady. What you found is quite timely and crucial. You are really a good candidate for an astronomer.”
The scientist's words meant a lot to her. She smiled so happily as it was the first time an adult had confirmed her dream.She made up her mind to run after her dream and nothing would stop her. The scientist invited her to work as an assistant, working with him.After years of hard work, Catalina, who had been equipped with abundant theory and practice, was admitted to an astronomy university. Her childhood dream finally became a reality. Nothing is impossible to a willing heart. However, to Catalina, it's the scientist's encouragement that pushed her so far.
