Smile, you’re on body cam
As camera technology gets smaller and cheaper, it isn’t hard to imagine a future where we’re all filming everything all the time, in every direction.
Would that be a good thing? There are some obvious potential upsides. If people know they are on camera, especially when at work or using public services, they are surely less likely to misbehave. Another upside is that it would be harder to get away with crimes or to escape from blame for accidents.
Body-cam data could also create a legal minefield. Arguments over the truth and interpretation of police footage(影像) have already surfaced. Eventually, events not caught on camera could be treated as if they didn’t happen. Alternatively, footage could be faked or doctored (伪造) to avoid blame or do wrong to others.
Of course, some people think that if you are not doing anything wrong, you have nothing to fear. But most people have done something embarrassing, or even illegal, that they regret and would prefer hadn’t been caught on film. People already remove their social media feeds or avoid doing anything wrong in public — for fear of damaging their reputation.
The always-on-camera world could even threaten some of the qualities that make us human. We are natural persons who enjoy talking about other people’s private lives and while those might not be desirable behaviours, they oil the wheels of our social interactions. Once people assume they are being filmed, they are likely to keep silent.
The argument in relation to body-cam ownership is a bit like that for guns: once you go past a critical threshold(临界值), almost everyone will feel they need one as an insurance policy. We are nowhere near that point yet- but we should think hard about whether we really want to say lights, body cam, action.
1.What does the underlined word “upsides” in Paragraph 2 refer to?
A. advantages. B. rules. C. shortcomings. D. dangers.
2.Why do people argue about police footage?
A. Police footage can show the truth. B. Events caught on footage are treated unfairly.
C. Police footage could be changed on purpose. D. Footage should not be filmed by police.
3.What does the author believe?
A. People behave well with cameras on.
B. People’s private lives should be respected.
C. Talking about others’ private lives promotes social interactions.
D. People keep silent before cameras when talking about themselves.
4.What is suggested in the last paragraph?
A. We don’t need a critical threshold. B. We should be cautious in adopting body-cam.
C. We need body-cam as an insurance policy. D. We haven’t decided whether to take action.

Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. Now, there is a new way we get the news: computer-created news readers.
Recently, China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real-life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese.
One Xinhua's report said machine learning was used to examine video images and sounds of the two newsmen, which look and sound like real people.
Some machine learning experts said the system showed off China's latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers.
On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.
Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to "remove the language barrier" for many different kinds of video across the Internet.
1.What does the author intend to do in Paragraph 1?
A.Introduce the topic of the text.
B.Summarize the different opinions.
C.Add some data about the AI presenters.
D.Compare different ways of getting news
2.What is the machine learning technology used to do?
A.To keep AI presenters from making any mistakes.
B.To make AI presenters speak more fluently.
C.To ensure images and sounds are like real persons.
D.To bring newscasts up to date every hour.
3.What are some people worried about when AI presenters were launched?
A.Robots will eventually replace human all over.
B.Robots may threaten some people's employment.
C.Robots may endanger most people's health.
D.Robots will rule over the world in the end.
4.From the last paragraph we know that______.
A.BBC has removed the language barrier in newscasts
B.BBC's news readers can speak different languages
C.BBC shows interest in Xinhua's AI news presenters
D.BBC has done similar experiments as Xinhua does

The smallest kids on Earth are much smaller than you or your baby brother or sister. They’re even smaller than the hairs on your head. We call them “NanoPutians”(纳米小人). Also known as NanoKids, the NanoPutians aren’t real people. They are actually tiny molecules (分子) made to look a little bit like people.
James Tour invented the NanoPutians as a way to teach kids about nanoscience, which refers to the study of things that are smaller than about 100 or 200 nanometers. “The exact size is less important than the possible applications of working with such tiny things,” Tour says, “Nanoscience is the study and development of the small so that it will affect the large.”
One of the goals of the research is to control individual atoms. Carbon, hydrogen, oxygen, and other types of atoms are the building blocks of the universe. They make up planets, rocks, people, trees, CDs --- all the stuff out there. “Most things that people build come together in a top-down way”, Tour says. If you want to make a table, for instance, you cut down a big tree, make wooden boards, and hammer them together. Nature, on the other hand, builds things from the bottom up. When atoms join together they make molecules. Each molecule has a certain shape, and a molecule’s structure determines what it can do. Molecules can make them come together to make a cell --- or a tree.
Tour and his co-workers turned these molecular structures into cartoon figures and made an animated(动画的) science video about the little people, set it to music and started showing it to kids in school while talking about how exciting research on small things can be.
“Learning about the NanoKids has opened up a world of possibility for real kids who ordinarily would rather not study biology, chemistry or physics.” Tour says. When you look closely enough, the really small can be really cool.
1.What is the purpose of inventing NanoKids?
A. To clone two really similar children.
B. To arouse kids’ attention of the scientific world.
C. To know more about the top-down way.
D. To keep up with the development of nanotechnology.
2.How did Tour introduce the research on small things to kids?
A. By producing wonderful music.
B. By performing a play acted by kids.
C. By making animated science videos.
D. By turning molecular structures into little kids.
3.Which section of a newspaper is the text probably from?
A. Science. B. Economy.
C. History. D. Entertainment.

Many of us enjoy doing it: you turn on the camera on your mobile phone and hold it at a high angle, making your eyes look bigger and your cheekbones more defined. You turn to your best side and click. There it is — your selfie.
Over the past year, “selfie” has become a well-known term across the globe. This August the Oxford dictionary added the word to their online dictionary and defined it as: “A photograph that one has taken of oneself, typically with a smartphone or webcam and up-loaded to a social media website.”
Today it’s not difficult to find social networking pages full of photos people have taken of themselves and their friends. And selfie culture has become especially relevant for young people. As many as 91 percent of teenagers have posted photos of themselves online, according to a recent survey by the US Pew Research Center.
So what are the reasons for the rise of selfie culture?
“The cult (狂热) of the selfie celebrates regular people,” Pamela Rutledge, a professor at the Massachusetts School of Professional Psychology, told Vogue magazine. “There are many more photographs available now of real people than models.”
Posting selfies also allows you to control your image online. “I like having the power to choose how I look, even if I’m making a funny face,” Samantha Barks, 19, a high school student in the US, told Vogue.
In addition to self-expression and documentation, selfies “allow of a close friendship for long-distance friends, because you can see each other’s faces every day”, wrote Casey Miller at The Huffmgton Post.
But US psychologist Jill Weber is concerned that selfies might lead to social problems, “There’s a danger that your self-esteem may start to be tied to the comments and ‘likes’ you get when you post a selfie, and they aren’t based on who you are — they’re based on what you look like,” Weber told Vogue. “When you get nothing or a negative response, your confidence can plummet.”
1.With the first paragraph, the author intends to .
A. tell us the fun of taking a selfie
B. describe what a selfie is

d. It is believed to be a helpful way to develop a new friendship.
e. It is considered a good way to stay connected with friends that are far away.
A. a, c, e B. b, c, d C. a, b, c D. b, d, e
3.What is Jill Weber’s attitude toward selfies?
A. She thinks they are a good form of self-expression and documentation.
B. She believes the disadvantages of selfies outweigh the advantages.
C. She is worried that people’s self-esteem might be affected by how others react to their selfies.
D. She thinks that selfies can help people learn about their friends based on who they really are.
4.The underlined word “plummet” in the last paragraph probably means .
A. rapidly develop B. greatly exaggerate

How can you find out what is going on inside a person’s body without opening the patient s body up? Regular X-rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X-rays to study and determine diseases and injuries within the body. X-rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner，however，uses a group of X-rays to give a cross-sectional (横截面) view of a specific part of the body. A fine group of X-rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photo-graphed for later use. Several cross sections, taken one after another，can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active，moving organs，just as a fast-action camera can “stop the action”，giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X-rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X-rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X-rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.
1.The underlined words “a foreign object” in Paragraph 3 most probably refer to .
A. a badly injured part inside the body
B. a new thing that is unknown to the doctor
C. a strange cell that has grown in the body
D. a thing that gets inside the body by chance
2.What is the special use of the latest CAT scanners?
A. It can take pictures of inside organs.
B. It provides clear photos of moving organs.
C. It won’t cause serious skin bums, cancer or other damage to the body.
D. It helps to find out illness inside a person’s body without opening it up.
3.What can we infer from this text?
A. Patients in front of CAT may suffer a bit of radiation,
B. Doctors need no opening-up of the body with CAT scanners.
C. CAT scanners are more expensive than regular X-ray machines.
D. CAT scanners can take photos of either the whole body or a part of it.
4.What can be the best title of this text?
A. The newest medical invention
B. A special X-ray machine to save lives
C. How to avoid the damage from X-rays
D. Advantages and disadvantages of CAT scanners

It’s natural to greet friends with a smile and a wave. 1. But what happens if your face and body send mixed messages? Would someone be more likely to believe the look on your face or the way you hold your body?
Scientists have recently tackled these questions. They found that when a person is looking at your face, she might not believe what she sees if your body language doesn’t match the feeling that your face shows.
2. Previously, they had found that the tone of a person’s voice can be more important than the words that are spoken. For example, most people tend not to believe a person who says in a flat voice, “I’m so excited.”
When it came to emotions conveyed by facial expressions and body language, most scientists suspected that the face was more important. To test if this was true, psychologists showed people a number of pictures of isolated(孤立的)faces and isolated bodies (with faces blurred out(模糊的)) that showed anger or fear. 3.
An angry face had low eyebrows and tight lips. A scared face had high eyebrow and a slightly open mouth. 4. A scared body had arms forward and shoulders square, as if ready to defend.
These results told the researchers that mixed signals can confuse people. Even when people pay attention to the face, body language subtly(微妙地) influences which emotion they read.
5. If you want to be understood, it helps to avoid sending mixed messages.
A. Studying such mixed messages is nothing new for scientists.
B. So, your body language is important for telling people how you feel.
C. Scientists feel new to study the mixed message that confuses people.
D. An angry body had arms back and shoulders at an angle, as if ready to fight.
E. Body language can sometimes be misunderstood in different culture backgrounds.
F. When you do this, your face and body work together to show your friends that you’re happy to see them.
G. They also showed pictures in which angry or scared faces were paired with angry or scared bodies

For the soldiers, the true technological hero may be the body armor (盔甲).
Capable of stopping most bullets, the body armor worn by all of the troops is being trusted for saving many lives. Soldiers shot at close range are walking away with no more than broken ribs (肋骨).
While the newest smart bombs get more attention, improvements in soldiers’ armor are improving safety on the battlefield. The new body armor in particular, may help reduce deaths in the firefights.
In addition to the lighter and more protective body armor, soldiers now wear more comfortable, stronger helmets.
“Everything they have is much better,” says Robert Kinney, director of individual protection at the Army’s Soldier Center in Natick, Mass. “It means an increase in their quality of life.”
The new equipment is a result of years of research and development at the lab.
The new body armor, named “the interceptor”, is similar to but stronger than ones worn by the police. It can also protect the neck. Two other plates are put into it and cover vital organs. As a result, far fewer deaths arrive at military hospitals with abdomen (腹部) or, chest wounds, says Air Force Maj. Mark Ervin, a surgeon at the Landstuhl Regional Medical Center in Germany. “That’s remarkable,” Maj. Ervin says.
Altogether it weighs 16 pounds, one-third lighter than the previous armor that protects only against shrapnel (弹片) but couldn’t stop bullets. The lighter weight is a welcome improvement for soldiers already carrying 100 to 120 pounds of gear.
Soldiers’ helmets have also been improved since the first Gulf War. They also offer more protection. They are capable of stopping handgun or small machine gun rounds, but not high-powered shots.
1.Why is the body armor regarded as a hero?
A.It’s able to stop all the bullets. B.It saves a hero soldier’s life.
C.It prevents rib injuries effectively. D.It reduces deaths among soldiers.
2.Which of the following best describes the new body armor?
A.Stronger. B.Heavier.
C.More expensive. D.More attractive.
3.What is the main idea of the text?
A.The new body armor is able to stop most bullets.
B.The new body armor has saved many lives on the battlefield.
C.Soldiers are equipped with improved body armors and helmets.
D.Helmets are as important as the body armor to soldiers.

The latest target for TV advertisers is children in Asia. Asian families are getting smaller and wealthier, and Asian children are watching more and more TV. It is said that the average Hong Kong child sees about 25,000 TV advertisements a year.
To get the attention (and the money) of these young audiences, the advertisers use little actors. “The kids share the same feelings with someone from their own age group,” says one advertiser, “so this kind of advertisement is more effective. And, of course, the little actors earn big money.”
Not everyone is happy to see kids turned into buyers. “Advertising to children is wrong,” said Pasty Liang, “because its aim is to make them ask their parents for money to buy things. Also, many things advertised, such as toys, are silly and encourage violence. If a child buys them, he or she will learn nothing.” Some educators believe that if young people watch the ads, they will become more and more materialistic.
Some people even think it wrong to use little actors in TV advertisements. “It is illegal for kids to work in factories, so why are they allowed to work in ads? Also, considering the high salaries, it is bad for children to have too much money.” said Elvis Hu.
As an advertiser, J W Lu clearly has his own opinion about this. “It is nothing wrong with children earning a lot of money or asking their parents to buy things for them. Besides, kids buy toy to have fun, not to learn from.”
Anyway, governments are beginning to take action to protect children. An ad would not be allowed to appear on TV if it made children feel inferior (低人一等的) because they didn’t own the advertised product.
1.The advertisers use little actors so that ________.
A. the ads can attract young audiences
B. the little actors can earn big money
C. the kids will share the same feelings
D. people will see more TV advertisements
2.What does the underlined word “illegal” mean?
A. Not liked by the children.
B. Not allowed by the law.
C. Not accepted by the public.
D. Not agreed to by the parents.
3.Who thinks it all right for kids to earn money by acting in ads?
A. Elvis Hu. B. J W Lu.
C. Pasty Liang. D. Some educators.
4.Which of the following is true according to the passage?
A. Little actors earn less money than adults.
B. Advertisers want children to learn from toys.
C. Some people are not for advertising to children.
D. Governments are taking action to protect advertisers.
5.What is the best title for the passage?
A. Little Actors or Adult Actors
B. How to Get Children’s Attention
C. Opinions about TV Advertisements
D. Children: New Target for TV Advertisements
