Online courses have become popular in many countries. There are different kinds of online courses, but most show a video of a teacher and students in a classroom. Students watch the video online and take part in online activities. Some courses are free and open to anyone. 1 Of course, watching videos on a screen is not the same as taking part in a real class.
2 In Singapore, eight schools have been chosen to try new ways of using technology in the classroom. The schools have tablets(平板电脑)and touchscreens instead of books and blackboards in the classrooms. 3 Through them, students can communicate with each other and work on projects together.
In South Korea, some students have been taught English by teachers in the Philippines and other countries since 2011. The teachers are in their home countries and are connected to the South Korean classrooms via the Internet. Instead of looking at a screen, the students interact with a robot in the classroom. The robot is controlled by the teacher. 4
Thanks to technology, more and more ways of teaching and learning are being developed.

A
Elon Musk, perhaps the world's most brilliant businessman, has a habit of making statements that stretch the bounds of believability.
On July 16th, 2019, he introduced a new type of brain-machine interface(BMI), starting from the design of a “neural lace(神经织网)”, a net of thin electrodes(电极) that capture the information from the brain. However, the electrodes must be flexible, so that they do not damage brain tissue and will last for a long time. And to make the implantation(植入) of so many electrodes safe, painless and effective, the process has to be automated.
Mr. Musk's team does indeed seem to have made progress towards these goals. Their presentation includes videos of a robot that is best described as a sewing machine. This robot grabs “threads”, and shoots them deep into the brain through a hole. The firm has also designed a chip that can handle signals from as many as 3,072 electrodes.
With all these technological breakthroughs, the firm now hopes to help people overcome such illnesses as blindness and paralysis. They designed a small device that would sit behind someone's ear, picking up signals from the implanted chip and passing them on as appropriate. In a few years, using a brain implant to control your devices may be as prevalent as wearing wireless earphones today. Finally, Musk predicts neural lace will allow humans to be combined with AI systems, thus enabling the species to survive.
Though, as this announcement shows, Mr. Musk does have a habit of presenting himself as the hero of the human race, at least the concept that some machines will come under the direct control of human brains seems possible to be carried out. The biggest barrier to this happening will probably not be writing the software needed to interpret brainwaves, but rather persuading people that the necessary surgery, whether by sewing machine or otherwise, is actually a good idea.
1.We can learn from the first two paragraphs that .
A.electrodes should be flexible to extend life
B.Elon Musk constantly comes up with unexpected ideas
C.a neural lace is used to store information from the brain
D.electrodes are implanted by top surgeons for safety reasons
2.What does the underlined word “prevalent” in Paragraph 4 probably mean
A.Useful. B.Common. C.Professional. D.Appropriate.
3.What is the hardest part of carrying out BMI
A.Convincing people to accept the surgery.
B.Developing devices to perform the surgery.
C.Writing the software to interpret brainwaves.
D.Informing people of the success of the surgery.
4.What is the best title of this passage
A.The Neural Lace, a New Type of BMI
B.Elon Musk, the Hero of Human Beings
C.Artificial Intelligence, the Way to Survive
D.A Brain Implant, a Step to Control Machines
B
John von Neumann was the oldest of 3 children of a banker, and his speed of learning new ideas and handling problems stood out early. At 17, his father tried to persuade him not to become a mathematician because he might lead a poor life being a mathematician, so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a PhD in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry.
In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people(Einstein was one of the others).
World War Ⅱ hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several outstanding contributions. After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was the president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer.
Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century.
Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend. He reported one accident this way,“I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path.”
5.According to the text, von Neumann's father believed that .
A.a mathematician couldn't earn a lot of money
B.a mathematician needed a good memory
C.von Neumann had the ability to learn two subjects at the same time
D.von Neumann had the gift for solving problems at a high speed
6.Von Neumann published his first book at the age of .
A.23 B.26 C.29 D.32
7.How did World War Ⅱ affect John von Neumann
A.He realized the importance of engineering.
B.He began to research how to put mathematics into practice.
C.He left college and served at the government department.
D.He lost interest in chemistry.
8.What can we conclude about von Neumann based on the text
A.He had three children.
B.He died in an accident.
C.He received many awards in his life.
D.He and Einstein were classmates at Princeton University.

How to Succeed in Science
To succeed in science, you need a lot more than luck. In my view, you have to combine intelligence with a willingness not to follow conventions when they block your forward path. Thus, these have come to be my rules for success.
1
That might sound proud, but the fact is that you must always turn to people who are brighter than you. It's like playing any game. Even as a child, I never wanted to play games with anyone who was as bad as I was. If you win, it gives you no pleasure. And in the game of science or life, the highest goal isn't simply to win; it's to win at something really difficult. 2
Take risks.
To make a huge success, a scientist has to be prepared to get into deep trouble. If you are going to make a huge jump in science, you will very likely be unqualified to succeed by definition. 3 This can be more than personally upsetting.
Never do anything that bores you.
My experience in science is that someone is always telling you to do things, and then leaves you alone. I'm not good enough to do well in something I dislike. 4
It's very hard to succeed if you don't want to be with other scientists, because you have to go to key meetings where you spot key facts that would have escaped you. And you have to chat with your competitors, even if you find them objectionable.
So my final rule is: 5
A.Meet challenges with great courage.
B.If you can't stand being with your real peers, get out of science.
C.Put another way, it's to go somewhere beyond your ability and come out on top.
D.Be sure you always have someone to save you from a deep mess.
E.Avoid foolish people.
F.In fact, I find it hard to do well in something I like.
G.Besides, you even have to be prepared to disbelieve your scientific heroes.

Stephen Hawking, the most outstanding physicist of his time, has passed away at the age of 76.
A family spokesman said Hawking, who was British, died peacefully early Wednesday at his home in Cambridge, England. Hawking was known worldwide for working to explain subjects like the beginning of the universe and the complexity of black holes. He was diagnosed with a disease called amyotrophic lateral sclerosis, or ALS, at age 21. At the time, doctors predicted he would only live a few years. But he proved them wrong by surviving for more than 50 years and continuing his scientific work.
In his 2013 book, My Brief History, Hawking wrote about his first learning of the illness, “I felt it was very unfair—why should this happen to me ” He added, “At the time, I thought my life was over and that I would never realize the potential I felt I had.” “But now, 50 years later, I can be quite satisfied with my life, ” he wrote.
A sign of his being admired came in October 2017, when Cambridge put Hawking's 1966 thesis on the Internet for the first time. Demand for the thesis was so high that it caused the university's website to go down.
Hawking said the belief in God who intervenes(介入) in the universe “to make sure the good guys win or get rewarded in the next life” was wishful thinking. “But one can't help asking the question: Why does the universe exist ” he said in 1991. “I don't know an operational way to give the question or the answer, if there is one, a meaning. But it bothers me.”
Hawking subscribed to human space travel to the Moon and Mars. He said such missions would help unite humanity in a shared purpose of spreading the human race beyond the Earth. “We are running out of space and the only places to go to are other worlds. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave the Earth,” he said last year.
1.What is Hawking's attitude towards life when just diagnosed with ALS
A.Optimistic. B.Hopeless.
C.Disappointed. D.Confident.
2.Why is Hawking in favor of human space travel to other solar systems
A.Because we have used up all space.
B.Because we have explored the Moon and Mars for a long time.
C.Because it can help spread the human race beyond the Earth.
D.Because it is a way to save the Earth.
3.What can be a suitable title for the text
A.Stephen Hawking Is Recognized for His Research on Black Holes
B.Stephen Hawking Supports Human Space Travel
C.Stephen Hawking Is a Worldwide Famous Physicist
D.Famous Physicist Stephen Hawking Died at 76

On a cold Friday night, a poor artist stood at the gate of the subway station, playing his violin. The young violinist was a student named Joseph at an art college, who did so every day in order to earn his tuition fees. He planned to attend advanced studies in Vienna and had booked the flight for the next morning. Though the music was great, people were quickly going home for the weekend. Joseph was playing his last chapter when a middle-aged man looking pretty excited slowed down his pace and put 50 dollars into the hat, for which Joseph was grateful.
The next night, the young artist came to the gate of the subway station as usual, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper, laid it on the ground and put some stones on it. Then he began playing the violin.
Before long, the young artist was surrounded with many passers-by, who were all attracted by the words on that paper. It said, “Last night, a gentleman put an unexpected thing into my hat by mistake. Please come to claim it as soon as possible.” It caused great excitement and curiosity. They were dying to know what the unexpected thing could be.
Paragraph 1:
Just at the moment the middle-aged man rushed through the crowd to the violinist.
Paragraph 2:

Paragraph 1:
Just at the moment the middle-aged man rushed through the crowd to the violinist. After glancing quickly at the paper on the floor, his face was aglow with excitement and disbelief. He took a deep breath and then stammered, “Is...is it a...a lottery ticket My five-million-dollar lottery ticket ” Joseph stared at him with a smile, nodding. Yes, Joseph recognized him. It was this middle-aged man who appeared extremely excited and generously put 50 dollars into his hat, just to which a lottery ticket was attached.
Paragraph 2:
The man thanked Joseph again and again because it was very essential to him. His company was facing bankruptcy, as a consequence of which he even couldn't pay his employees. Yesterday good luck seemed to have dropped from the heaven that he unexpectedly won the lottery!Having heard this, Joseph felt it was more worthwhile to change the flight and return the lottery ticket to the man who showed mercy to him—love comes from love.Unit 1Science And Scientists同步巩固练-part 2

What are the biggest problems that the society will have to deal with in the new age There are diseases like AIDS and cancer. There's climate change, of course. And what about producing enough cheap food and energy for the world's growing population Who's going to handle all these terrible problems Yes, politicians and world leaders will have a big part to play. Yes, businesses will need to create the economic wealth to pay for some of these things. But who's going to make a much greater difference to something like AIDS or climate change It's going to be a scientist. It is the scientists who can transform some new results of science into new technologies to solve these problems.
If you like thinking about the world around you, why not become a scientist It doesn't mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do multiple amazing things that are actually interesting!
Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic(法医的) scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow's scientists. Don't think a scientist is far away! Maybe you like cooking. You could be a food technologist helping to keep fruit and vegetables fresh for longer. Perhaps sport is your thing. Do you know that most top athletes work with sports scientists in order to improve their performance You could even be a science writer who gets to spend the life studying the latest advances and sharing them with the world.
