These days no car show is complete without an electric car, and the 2011 North American International Auto Show in Detroit, US, which ran from January 10 to 23, was no exception.
Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV. BMW and Volvo also had prominent displays at the show, proving that they can produce practical, yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries, improved performance and greater consumer acceptance could make 2011 the “year of el
ectric car”.
It’s long been clear that electric cars score heavily for convenience. They are, for instance, much easier to maintain than gasoline-powered cars. When the battery runs out, you simply replace it or recharge it, just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline. Better yet, electric cars don’t emit exhaust fumes. As a result, they don’t produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly. So, what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users. However, it is also a potential obstacle. For a start, installing charging stations in owners’ homes will be a challenge, particularly for those who have to park several blocks away from their homes.
Also, charging the car’s battery still takes quite a long time. It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50 miles (80 km) or less between charges. In cases where a driver wishes to charge the car primarily at home (perhaps overnight), this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular. A hybrid car has more than one energy source, usually a traditional gasoline fuel tank and an electric battery. It’s like a more practical version of an electric car: It’s greener than a conventional vehicle, with fewer CO2 emissions, yet it also doubles as a conventional vehicle.
“I would say that hybrid is a transition to fully electronic,” Road and Track magazine editor Richard Horman told Detroit News during the show. “The trend is for lighter, smarter, more economical cars. Of course
, electronic vehicles are meant to be that way.”
This sounds promising, particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However, it seems that the technology associated with electric cars is not yet able to fully meet people’s expectations. Don’t expect gasoline-powered cars to disappear from roads just yet. What made electric cars more convenient?
| A．Easier maintenance. | B．High scores on the show. |
| C．Practicality and large space. | D．Much lower prices. |
Which of the following could NOT act as a potential obstacle of electric cars?
| A．It is rough work to install charging stations at home. |
| B．It is time-consuming to charge the batteries. |
| C．The ranges between charges are limited. |
| D．There’s no need to fill the tank with petrol. |
In Paragraph 10, the underlined word “hybrid” is probably closest in meaning to ________.
| A．gasoline | B．electric | C．combined | D．separated |
The writer’s purpose in writing this passage is to_________.
| A．introduce the 2011 Auto Show in US | B．get readers informed of electric cars |
| C．comment on different types of cars | D．advertise for electric cars |

It is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.
How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive tools, you are going to be built up on them.
Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.
Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you, who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.What’s the meaning of the underlined phrase “freak out” in Paragraph 1?

It was the end of my junior year, the weekend before prom (毕业舞会). I was riding with some friends, and a bottle was passed around the car. Everyone was taking swigs(一大口). When the bottle got to me, I thought:“What should I do?”I took a swig. It was the biggest mistake of my life. I had to drive home later that night.
I went back to my car, got in and drove off. At a stop sign I saw a policeman sitting in the parking lot across the street. His headlights were turned on, and I knew he was going to follow me. Then he flashed his lights at me. All I could think was: “Oh no, that swig!”
I pulled over and waited for him to come to my door. It felt like forever. “Can I see your license and registration, please, Miss?” I gave them to him. He took them and went back to his car for a while. When he returned, he asked if I had been drinking.
“No,” I said. He asked me to step out of my car.
“Walk heel to toe down the white line, please.” I passed the test. Next he had me stand on my left foot, lift my right foot and hold it for 30 seconds. I’m not the most coordinated (动作协调的) person and I can’t even walk and chew gum at the same time, so, needless to say, I didn’t pass. Then he asked me to take a breathalyzer test.
That was where I messed up. I told him I didn’t want to and didn’t understand why I had to. The officer asked me three more times, and I continued to refuse. He told me to turn around and place my hands behind my back. He arrested me right then and there.
The policeman drove me to a police station 20 minutes from my home. He called my parents and told them where I was.
I went to court two months after that, charged with refusing to obey an officer. I got a $700 (4,340 yuan) fine and 40 hours of community service. I’ll be on probation (缓刑) for a year, and I’ll have to take the driving test again. I lost my license for a whole year.
This was a huge learning experience for me. It opened my eyes to how easy it is to make a stupid decision. I want everyone reading this to know that it’s not right to drink and drive. It definitely isn’t worth losing your license over.From the first paragraph, we can conclude that the author __________.

What's driving the rise of obesity in the United States? A group of economists argued in a recent study that big-box grocers, warehouse clubs and fast-food restaurants are key contributors to the county's obesity epidemic(流行病).
General economic factors, ranging from unemployment to income, as well as the financial
or time costs of eating and physical activity account for 43 percent of the rise in obesity, according to a recent study published by the US National Bureau of Economic Research, as the adult obesity rate in the United States has surged from 13 percent in 1960 to 35 percent in 2012.
"Supercenter/warehouse club expansion and increasing numbers of restaurants are the leading drivers of the results," the study concluded. "We show that supercenter/warehouse club density increases the probability of weight loss attempts, raising the possibility that cheap food from these retailers triggers self- control problems."
The study suggests that the rise of supercenters and warehouse clubs, like Walmart and Costco, may impact Americans' eating habits as they make calorie-rich food cheaper and more accessible, and save customers a lot of time.
"Food's gotten cheaper and more readily available, so we eat more of it. It's really simple," said Charles Courtemanche, co- author of the study and a health economist at Georgia State University, in an interview with National Public Radio (NPR). "At least a sizable portion of the rise in obesity can be characterized as response to economic incentives."
Obesity, defined as a body mass index (BMI) of at least 30, leads to adverse health conditions such as heart disease, diabetes, high blood pressures and stroke.
Obesity has become a major public health concern in the United States as the nation has one of the highest obesity rates in the world, according to the Organization for Economic Cooperation and Development (OECD).What does the underlined word “trigger”mean?

Not enough American students want to be engineers, mathematicians, or scientists. The Obama administration wants to change that. They are spending money to do it. The government will invest three billion dollars in the education of young Americans in science, technology, engineering, and math. The four areas together are known as STEM.
Many jobs in the STEM fields will open in the coming years. The U.S. government's investment aims to increase the number of Americans who can take those jobs.
Yet girls appear far less interested in STEM subjects than boys. Only 25 percent of STEM students are girls.
Camsie McAdams is at the U.S. Education Department. She says girls simply do not feel welcomed in STEM subjects. Ms. McAdams says young women look at industries such as engineering and computer science and see most of the leaders are men.
Debbie Sterling is an engineer. She invented a construction toy for girls. The name of the toy is "Goldie Blox." Ms. Sterling hopes Goldie Blox will help girls develop spatial skills. Spatial skills help engineers and builders to think about objects in three dimensions.
To interest girls, Sterling created the character "Goldie." Goldie does not care about beauty or clothes. Goldie tells stories, solves difficult problems and creates pretend worlds.
Experts say parents should do more than just buy toys to interest their girls in STEM subjects. They should also provide a good education. At school, girls should participate in projects that require teamwork and creative thinking.
Women in scientific and technical jobs are also working to encourage young women to explore STEM. One is Anu Tewary. She studied Applied Physics and worked for technology companies. After she had a daughter, she started Technovation Challenge. The challenge is an international competition for young women from 10 to 18 years old.
Technovation offers girls the opportunity to learn how to start a company and become high-tech entrepreneurs. Since 2009, over 2,500 girls from 28 countries have developed 650 mobile phone applications. They learned to launch start-up companies through Technovation.
There's a good chance that soon, more young women using mobile phones will also be developing programs for them.Why don’t the girls take jobs related to STEM subjects?
| A．Because they are less intelligent than boys. |
| B．Because they are forbidden to. |
| C．Because they lack interest and certain skills. |
| D．Because they are not welcomed. |
What should parents do to interest girls to enter STEM field?
| A．Just buy some toys for them. |
| B．Encourage them to take these subjects. |
| C．Explain to them the advantages of these subjects. |
| D．Attract them by giving them some rewards. |
The character "Goldie" can help _____.
| A．to improve the ability of telling stories |
| B．to develop spatial skills |
| C．to learn some knowledge of dressing up |
| D．to enlarge vocabulary |
Which statement is the writer likely to agree with?
| A．Girls are as intelligent as boys. |
| B．Jobs in the STEM fields aren’t available for girls. |
| C．The government is satisfied with the current situation in STEM. |
| D．Girls are looked down upon in jobs related to STEM. |
Which of the following is right about Technovation Challenge?
| A．It was founded by the government. |
| B．It is intended for girls of all ages. |
| C．It helps girl to overcome difficulties in their life. |
| D．It gives girls chances to learn knowledge about technology companies. |

It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama’s Dreams From My Father and how it had changed my views of our President. A friend I was talking to agreed with me that it was, in his words, “a brilliantly written book”. However, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.
And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven’t. In the World Book Day’s “Report on Guilty Secrets”, Dreams From My Father is at number 9. The report lists ten books, and various authors, which people have lied about reading, and as I’m not one to lie too often (I’d hate to be caught out), I’ll admit here and now that I haven’t read the entire top ten. But I am pleased to say that, unlike 42 percent of people, I have read the book at number one, George Orwell’s 1984. I think it’s really brilliant.
The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austen, Charles Dickens, Fyodor Dostoevsky (I haven’t read him, but haven’t lied about it either) and Herman Melville.
Asked why they lied, the most common reason was to “impress” someone they were speaking to. This could be tricky if the conversation became more in–depth!
But when asked which authors they actually enjoy, people named J. K. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story (I’ll come clean: I do this and am astonished that 58 percent said they had never done so).What is the meaning of the underlined word “liar”?
| A．A person who hates books. |
| B．A person who tells lies. |
| C．A person who loves reading. |
| D．A person who is honest with everything. |
From the second paragraph we can know _____.
| A．only 42 percent of people have read George Orwell’s 1984 |
| B．two thirds of people haven’t read a book. |
| C．“Dreams From My Father” is listed the first of the top ten books |
| D．the writer haven’t read all of the top ten books |
Why does a person lie about books?
| A．Because they want to appear learned. |
| B．Because they want to attract others’ attention. |
| C．Because they do so out of habit. |
| D．Because they want to play tricks on others. |
Which of the following statement is right?
| A．The writer often leaves a book unfinished. |
| B．The writer was once caught out for telling lies. |
| C．The writer often reads the end of a book first before finishing the story. |
| D．The writer likes Barack Obama from the very beginning. |
What do you think of the author?
| A．Thoughtful and talkative. |
| B．Smart and helpful. |
| C．knowledgeable and experienced. |
| D．Wise and honest. |
