题目内容

I don't ever want to talk about being a woman scientist again. There was a time in my life when people asked constantly for stories about what it's like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-lime and the nature of black holes.

At 19, when I began studying astrophysics, it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement―jobs, research papers, awards― was viewed through the lens of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus  right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.

Today I research and teach at Barnard, a women's college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don't dismiss those concerns. Still, I don't tell them "war" stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that's a sight worth talking about.

 

67. Why doesn't the author want to talk about being a woman scientist again?

      A. She feels unhappy working in male-dominated fields.

      B. She is fed up with the issue of gender discrimination.

      C. She is not good at telling stories of the kind.

      D. She finds space research more important.

 68. From Paragraph 2, we can infer that people would attribute (归结于) the author's failures to _______

     A. the very fact that she is a woman.

B. her involvement in gender politics.

C. her over-confidence as a female astrophysicist.

D. the burden she bears in a male-dominated society.

69. How does the author feel when talking about her class?

A. worried       B. satisfied       C. excited       D. concerned

70. What does the image the author presents to her students suggest?

    A. Women students needn't have the concerns of her generation.

    B. Women have more barriers on their way to academic success.

    C. Women can balance a career in science and having a family.

D. Women now have fewer problems in pursuing a science career.

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 electric 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.

1. What made electric cars more convenient?   

A. Easier maintenance.                  B. High scores on the show.

C. Practicality and large space.            D. Much lower prices.

2. 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.

3.In Paragraph 10, the underlined word “hybrid” is probably closest in meaning to ________.

A. gasoline       B. electric           C. combined     D. separated

4.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
