On a Saturday morning earlier this September, the world got its first look at the Strati. This electric vehicle is unlike any other currently on the road. It rolls on four wheels, but its body and chassis(底盤(pán)) weren't built in a factory. Instead, Strati's designers used a technology called 3-D printing. It created those parts of the car in one piece, from the ground up.
“Compared to a typical vehicle on the road, the Strati definitely looks different,” says Greg Schroeder, a senior research engineer at the Center for Automotive Research in Ann Arbor, Mich. He did not work on the new car. His organization studies trends and changes in th e auto industry.
It took 44 hours to print the new car at the International Manufacturing Technology Show in Chicago. Over the next few days, the car's designers installed additional parts. These included the car's engine, brakes and tires. Then, early on September 13, Jay Rogers climbed into the car, started its engine and drove the vehicle onto the street. Rogers helped found Local Motors. It's the Arizona-based company behind the Strati. Two weeks later, his team printed a second Strati, and just as fast, at a fair in New York City.
Justin Fishkin, a local Motors official, sees the Strati as a window into the future. Today, car buyers are limited in their choice of a vehicle. They can order only what car companies have already designed. But in the future, he says, you may be able to design your own car online and then get it printed to order.
Manufacturing experts say 3-D printing has begun to revolutionize how they make things. The technology has been around for decades. But these machines used to be so expensive that only large companies could afford them. In the last few years, though, that has changed. Many of the machines are now inexpensive enough for small companies—or even individuals —to own. Some local libraries make them available to the public. High Schools are beginning to use them in classrooms. Wide access to these printers means people can now design and print a wide variety of new things.
The car's printer is a one-of-a-kind device.
The technology behind the 3-D printer used in Chicago is an example of additive manufacturing. This proce ss builds solid objects, slice by slice, from the bottom up. (“Strati” means layers, in Italian.) A mechanical arm moves a nozzle from one side to another, back and forth. As it moves, the nozzle deposits a liquid—often melted plastic or metal (but it could be food, concrete or even cells) —that quickly hardens or bonds to become solid or semi-solid. This creates a single, thin layer. Once a layer is complete, the printer starts depositing the next one.
“There's a lot of interest in 3-D printing in the auto industry,” says Schroeder. Right now, the technology is particularly useful for building models of cars or car parts.
To compete with current auto manufacturers, the 3-D printer would have to increase in a hurry, Schroeder says. By contrast, he notes, a Ford F-150 pickup truck rolls off an assembly line at a rate of roughly one per minute. To print as many Stratis would require many more printers. Schroeder says he doesn't see 3-D printing soon taking over for such high-volume manufacturing. But, he adds, “Who knows what will h appen in the long term?”
Scientists at Oak Ridge National Laboratory in Tennessee designed the 3-D printer used in Chicago. Lonnie Love, a research scientist at the lab, led the effort.
Additive manufacturing often is slow and expensive. It also may produce materials that are unreliable, Love says. So for two years, his team searched for ways to make 3-D printing better. They built new machines and tested them over and over.
All of that work paid off: their new machine is fast and uses less expensive material than earlier printers. In addition, it prints a plastic embedded with fibers of carbon to produce a stronger material. This helps ensure the material won't crack or break under pressure.
(1)Which of the following statements about the first Strati is TRUE?
A.It was born in a car factory in Chicago.
B.All parts of it were not made by using a technology called 3-D technology.
C.It is a pity that it has not run on the street so far.
D.Many senior research engineers worked on it, including Greg Schroeder.
(2)What can we infer from Paragraph 5?
A.Large companies are always rich enough to buy expensive things.
B.Now High Schools are beginning to use 3-D printers in classrooms.
C.Wide access to 3-D printers has made it possible for people to order novel things online.
D.High prices of new products can stop them from being used widely in the beginning.
(3)What does the word “nozzle” in Paragraph 7 possibly refer to?
A.A single, thin layer.
B.A part of the 3-D prin ter.
C.A solid or semi-solid object.
D.A person who operates the machine.
(4)Why did Lonnie Love make efforts to improve 3-D printing with his team?
A.Because additive manufacturing might produce unreliable materials.
B.Because he just was interested in making new things.
C.Because he just wanted to build new machines and test them
D.Because additive manufacturing is always slow but inexpensive.
(5)Which of the following can be the best title for this passage?
A.3-D Printers Are Coming
B.3-D Printers Are Becoming Well- Known
C.3-D Printers Are Becoming Cheaper
D.3-D Printers Are Making Cars

Dear Editor,
I'm writing to tell you about a food poisoning accident. Several days ago, my neighbor ate a bag of food buying from the market. After the meal, they had stomachaches and their faces turn pale. Lucky, one of their friends found the accident and immediately called an ambulance, which carried them quickly to a hospital. After several hours' treatment they finally escaped of death.
As some businessmen are only interested in making money to become rich quickly, we seldom care about the necessary safety measures or which happens to buyers. They must be have charged by law. Meanwhile, I do hope whole society can realize the important of food safety.

【題目】根據(jù)短文理解,選擇正確答案。
My friend BJ Gallagher told me a great story recently, about her own experience with resentment (憤恨). She once worked as the training manager for a large newspaper, where she found the corporate culture extremely frustrating. The company was a hundred years old and their past success ha d blinded them to the need for change. Finally, after butting heads with several senior executives (主管) many times, she left the company. But she found that she hadn't left her resentment, frustration, and anger behind when she resigned.
“I finally decided to write about my experiences and my feelings at the newspaper. I wanted to be rid of that company and those people, once and for all. So I wrote and I wrote. It wasn't just a story that poured out; it was a whole book! We called it A peacock in the Land of Penguins. I was the peacock and those newspaper executives were the penguins.”
“It took me several more years to finally get over my negative emotions. Through a lot of soul-searching and reflection, I finally was able to let go of my resentment. I came to see that there was nothing personal in the way they treated me, and they were good people doing what they thought best for the company. I was the one who had made it personal. I thought they were making my life miserable on purpose.”
“Finally, the time came when I decided to make amends (彌補(bǔ)) for the sharp, angry things I had said about the company. I invited my former boss to dinner and made my apology. It was a great healing process for me. I finally felt free of the resentment that had been eating me up.”
“What was the final outcome?” I asked her.
“Gratitude,” she replied. “Not only wasn't I resentful any more, I was grateful to the company. If I hadn't had those painful experiences, I would never have written a book. And the book became hugely successful – now published in 21 languages; it transformed my business.”
(1)What made BJ Gallagher frustrated in the company?
A.Unfair treatment by the senior executives.
B.The culture and tradition of the company.
C.The strict rules in the company.
D.Her low position in the company.
(2)Why did BJ Gallagher write about her experiences and feelings at the company?
A.To make peace with the executives.
B.To make suggestions to the company.
C.To do soul-searching and reflection.
D.To express her anger.

People often have trouble (get) used to a new culture because they need a long time to adapt to it. They are usually curious they first arrive in a foreign country and sometimes they may get confused about what to do. However, if they stay for long time, they may start to feel different (stage) of culture shock. They can feel lonely or sad because they can't deal with the local people. How (quick) people get used to culture differences may depend on the way they (learn). That's a problem if they can't speak the language. So the first important thing is to learn to speak the local language. On other hand, some can study the situation and make good guesses about the culture. When they finally begin (understand) some of the language and make some new (friend), they will gradually enjoy themselves and feel (comfort). Then they can live an easy life in a completely new culture.

【題目】根據(jù)短文理解,選擇正確答案。
As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.
Procrastination is the thief of time and a lot of students suffer form it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely are doing nothing either.
Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).
According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.
Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is non sense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.
Pelling also points out that procrastination feels particularly delinquent(過(guò)失的) in a society that thinks of speedy action as admirable, and, at times, even as a moral good.
Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.
(1)Which behavior belongs to procrastination?
A.Never dream away the time.
B.Always complete the tasks ahead of time.
C.Never put off till tomorrow what should be done today.
D.Always wait to work until the “good mood” or “good time”.
(2)According to the passage, which of the following statements is NOT TRUE?
A.Procrastination makes people waste their time.
B.Speedy action is considered as a moral standard in the society.
C.procrastinators usually complete their tasks perfectly.
D.Procrastination is common among people.
(3)What is most likely to be discuss ed in the paragraph that follows?
A.Ways to handle the study pressures.
B.Introduction to the book The Procrastination Equation.
C.More examples to illustrate procrastination
D.Measures to deal with procrastination.
