【题目】See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer. You might find it hard to believe that you could actually “print” an object like you would draw a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3D printer uses are mainly plastic, resin(树脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20,000, while now they cost only about ￡1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes, bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?
【1】According to the article, in the future, the 3D printing technology will _______.
A. enable people to make better purchases online
B. change the way we make many products
C. be applied as widely in our daily life as computers
D. shorten the time it takes for people to get what they buy online
【2】What happened in the 3D printing industry last year?
A. The 3D printing technology was taken out of the factory.
B. The 3D printing technology began to be used in various fields.
C. The 3D printer was used for medical treatment for the first time.
D. The 3D printer became more affordable for consumers(消费者).
【3】What is the best title of the passage?
A. Great Demand for 3D Printers
B. Technology in the Future
C. Online Shopping Disappearing
D. Printing out Everything
【4】How is the last paragraph developed?
A. By giving examples.
B. By making comparisons.

【题目】When I graduated from college I dreamed of being a television news reporter. Having no experience, I had to work in a small town until I finally got my big break in the form of a job in Boston. I made it.
Soon, reality set in. I was too often sent to run after accused criminals out of courts, waiting outside of crime scene tape or at the doorstep of a family still crying for tragedy (悲剧). My breaking point came the day I accidentally informed a young woman that her mother died. It was the worst day of my professional life and the day I decided I no longer wanted to shine a light on these stories. My career was ebbing, and at the same time my personal life was too-I divorced.
My mom had always told me “When you’re feeling extremely upset, go help someone else.” So I started seeking out stories of people who had been in the news under tragic circumstances but were doing something inspiring with their lives: a young girl who was paralyzed (瘫痪的) by an accident but was uplifting her classmates with her positive spirit, a blind and autistic (自闭的) musician who learned to play 27 instruments, a disabled soldier who opened his own art studio. I started to tell and promote stories like them.
Over the last 10 years I have discovered my kindness gift: my ability to see the beautiful side of a person and reflect it back to them and the world. In telling stories of people turning their own hurt into acts of helping others I have become more sympathetic, more grateful and kinder. I have learned kindness is who we are, that our power for it is limitless and that, as we shine a light on it, it grows.
【1】What changed the author’s working direction in his job in Boston?
A. The tragedy in the society B. The low payment of the job
C. The hurt from his divorce D. The fear of cruel criminals
【2】What is the meaning of the underlined word “ebbing” in paragraph 2?
A. taking off
B. getting into trouble
C. unchangeable at all
D. dull but important
【3】What the author’s mother said means .
A. helping others is a way to escape from reality
B. helping others can comfort your soul
C. the best way of helping others is telling stories
D. it is difficult to make contributions to helping others
【4】According to the last paragraph, what does the author advise us to do?
A. To tell inspiring stories.
B. To fight against criminals.
C. To ignore our own hurt.
D. To do as much kindness as possible.

【题目】阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。
The British have many traditions but there is nothing more typical than taking afternoon tea. We know the Brits have a love affair with drinking tea, with more than 160 million cups 【1】 (drink) every day, but it was the invention of afternoon tea that turned tea-drink into 【2】 popular pastime.
This sociable feast involves drinking good quality tea 【3】 (comfort) while nibbling (小口吃) on nice sandwiches, scones with jam and cream and a selection of small cakes. And, of course, it can only happen in the afternoon! Afternoon tea, which 【4】 (design) as a light snack to bridge the gap between lunch and dinner, dates back to the 1840s. It went on to become a 【5】 (fashion) social occasion for the upper classes.
Now there is a resurgence (复苏) in its 【6】 (popular) in the UK and it is available to anyone who can afford it. 【7】 it can be enjoyed at home, the best way to experience it is at a smart hotel or café. But if you’re thinking of visiting such a place 【8】 (enjoy) afternoon tea, remember the rules you must follow to avoid 【9】 (ask) to leave.
Writer Henry James once noted that “there are few hours in life more agreeable than the hour dedicated to the ceremony 【10】 (know) as afternoon tea.” I’m sure once you have tried it, you will agree.

【题目】People aren’t walking any more—if they can figure out a way to avoid it.
I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn’t in any hurry, either, I had merely become one more victim of a national sickness: motorosis.
It is an illness to which I had thought myself immune（免疫的）, for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day’s walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced—and beat—a teenage football player the 168 steps up the Stature of Liberty.
Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercises. A person who avoids exercise is more likely to have illnesses than one who exercises regularly. And walking is an ideal form of exercise—the most familiar and natural of all.
It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.
The car is a convenient means of transport, but we have made it our way of life. Many people don’t dare to approach Nature any more; to them the world they were born to enjoy is all threat.To them security isa steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.
I say that the green of forests is the mind’s best light. And none but the man on foot can evaluate what is basic and everlasting.
【1】What is the national sickness?
A. Walking too much.
B. Travelling too much.
C. Driving cars too much.
D. Climbing stairs too much.
【2】What was life like when the author was young?
A. People usually went around on foot.
B. People often walked 25 miles a day.
C. People used to climb the Statue of Liberty.
D. People considered a ten-hour walk as a hardship.
【3】The author mentions Henry Thoreau to prove that _____.
A. middle-aged people like getting back to nature
B. walking in nature helps enrich one’s mind
C. people need regular exercise to keep fit
D. going on foot prevents heart disease
【4】What's the author's intention of writing this passage?
A. To tell people to reflect more on life.
B. To recommend people to give up driving.
C. To advice people to do outdoor activities.
D. To encourage people to return to walking.

科目：高中英语 来源： 题型：
【题目】Sandra Bullock turned 51 last month. But because she looks exactly the same as she did in Miss Congeniality, a movie filmed back in the 20th century, everyone calls her “ageless.” Bullock is just one of a number of stars in their 40s and 50s who’ve had birthdays recently but have not gotten older, unlike the rest of us in their age group. Take Halle Berry. One website put a photo of her 20 years ago next to one of the newly 49-year-old Berry and dared us to choose which was which. “This Is What 49 Looks Like,” it said. Seriously, if that’s what 49 looks like, I must be 71.
However, even a generation ago, famous faces evolved. Look at a picture of Grace Kelly at age 52 in the early 1980s. She looks like a beautiful middle-aged woman. Today she’d look old for her age.
The goal now is to prevent aging while you are still young, using all the magical nonsurgical options medicine has to offer. Eventually these techniques will become less expensive, and ordinary people my daughter’s age will have them. Already anti-aging is starting to be considered maintenance, like coloring your hair. My friends and I find ourselves openly debating techniques that we used to make fun of. Does fat-freezing work? How much time do you have to spend in the gym to keep the body of a 35-year-old after 50? It’s all so exhausting. But members of the next generation have it tougher. They’ll have to ask themselves whether they want to spend their youth trying not to get old. I’ve already seen “Sexy at 70” headlines. Will everyone be expected to go to their graves(坟墓) looking hot?
I also have to wonder what else we are slowing along with age. How do you move on if you’re working so hard to stay the same? And besides, if you’ve known the ache of watching a daughter pack up for college, you know you can’t stop the clock.
【1】In the author’s eyes, Sandra Bullock ________.
A. doesn’t deserve her name
B. doesn’t look her age at all
C. behaves like a young woman
D. looks younger than Halle Berry
【2】The example of Grace Kelly is given to show ________.
A. physical beauty never lasts long
B. there is no such thing as agelessness
C. people’s attitude towards aging has changed
D. stars pay too much attention to their appearance
【3】Where do the author’s concerns about anti-aging techniques lie?
A. They expose people to danger.
B. They make people feel stressful
C. They are too expensive for ordinary.
D. They encourage comparisons among people.
【4】What’s the purpose of the text?
A. To show the burden of youth.
B. To offer tips on how to look hot.
C. To advise people to accept aging.
D. To comment on some famous stars.
