【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?

【题目】Shopping in the United States changes a lot. About ninety years ago most people shopped in small stores that were owned by one person or a family. Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week.

Then about sixty years ago, supermarkets were born. In a supermarket, people could get all the different kinds of food they needed without going to different stores.

The next big change in shopping in the United States was the shopping mall. A shopping mall is a group of stores under one roof. Because malls allowed people to shop without worrying about the weather, they soon became very popular. The mall became a place for people to socialize in addition to shopping. If you walk through a mall, you will see older people sitting, chatting and drinking coffee. Malls are places for teenagers to hang out. Many teens will often just“go to the mall”and spend time with their friends.

The recent change in American shopping was the superstore. Large chain stores such as WalMart, Office Depot and Toys“R”Us have been built all across the United States. Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores.

Sometimes, when they are built near small towns, many of the small town stores have to close. They just cannot compete with their giant neighbors.

And now, online shopping is becoming more and more popular all over the States. People are too busy to go to the physical stores, so they go shopping over the Internet. Online shopping has lots of advantages. For instance, online stores are usually available 24 hours a day. Searching or browsing online shops can be faster than browsing the physical stores. While, online shopping also has its disadvantages. People are at higher risk of being cheated on the part of the merchant than in a physical store. And privacy of personal information may be let out.

【题目】Winters are long and unforgiving in North Dakota. The winter of 1996 was especially brutal. It was a hard time in my own life too, A neck injury had kept me flat in bed for nearly a year. “Just in time for Easter,” my husband, Dick, said. But how could I feel the joy when the snow was four feet deep and I had months of painful physical treatment ahead?

I was doing the dishes one day, feeling hopeless when there was a tap against the glass. It was a branch of the troublesome cottonwood (棉白杨).Back in the fall of 1979, it was a new subdivision (分支) then, an eight-foot stick. The people who’d briefly occupied the house before us had placed the pipe from the pump next to it. The earth was so wet that the poor thing had fallen down, most of its bare root system pointing skyward, and blowing hopelessly back and forth in the cold wind. Dick decided to pull it out one day, but I disapproved of it.

“Look at how hard it’s trying!” I said, pointing to the way it strongly kept hold of the earth. “It deserves a chance.”

Dick borrowed some tools. We packed dry soil around the tree and put up some stakes () into the ground, making it stand upright. That winter was still terrible. Surprisingly, in the spring my “rescue stick” put forth a few leaves, then with lots of branches. The year after that, we were able to remove the stakes. By the 1990s that little stick was a giant, towering over the house.

Now the tapping at the window continued, louder as the wind picked up, almost as though to tell me to look up. At last, I did. I caught ray breath. In the window against the icy blue sky, thousands and thousands of fresh red buds were waving in the wind.

The tree was bursting with life and I had a wonderful Easter.

C. long. D. warm.

C. By distributing chemical fertilizer.

C. To tell us that the tree had survived from the awful winter

4】【4Which of the following can serve as the main idea of the passage?

A. A friend in need is a friend indeed,

B. There is no garden without its weeds.

D. Where there is life, there is hope.

【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.
