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-time 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 (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.
Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations（挑衅）: I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.
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.

Global warming may or may not be the great environmental crisis of the 21st century, but—regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.
Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and—without major technological breakthroughs—we can’t do much about it.
From 2003 to 2050, the world’s population is estimated to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn（注定）the world’s poor people to their present poverty and freeze everyone else’s living standards. With modest economic growth, energy use and greenhouse emissions more than double by 2050.
No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.” Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.
The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.
The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.
What is said about global warming in the first paragraph?

A．It may not prove an environmental crisis at all.

B．It is an issue requiring worldwide commitments.

C．Serious steps have been taken to avoid or stop it.

D．Very little will be done to bring it under control.

According to the author’s understanding, what is A1 Gore’s view on global warming?

A．It is a reality both people and politicians are unaware of.

B．It is a phenomenon that causes us many inconveniences.

C．It is a problem that can be solved once it is recognized.

D．It is an area we actually have little knowledge about.

A．Global warming is more of a moral issue than a practical one.

B．The ultimate solution to global warming lies in new technology.

C．The debate over global warming will lead to technological breakthroughs.

D．People have to give up certain material comforts to stop global warming.

Here’s one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit (发出) energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out.
The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head — one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off.
With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans.
The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active ― even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone.
Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is “not really safe,” Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology.
For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a speakerphone or keep the phone away from your head.
Which of the following statement is true?

A．Scientists are sure that cell phones are bad for the brain.

B．In the experiment, the left side of the brain used more glucose.

C．Radiation from the phone probably causes the change in the brain.

D．Henri Lai wrote a lot of articles about this new study.

Why weren’t the participants allowed to have a conversation on the phone during the experiment?

A．Because that would be too noisy and bad for the experiment.

B．Because they really looked strange and no one wanted to talk to others.

C．Because they were given PET scans and they lost the ability to talk.

D．Because the scientists want to be sure of the accuracy of the experiment.

What is glucose?

A．A type of sugar that provides vitamin to brain cells.

B．Something that the right side of the brain used.

C．A type of sugar that gives energy to brain cells.

D．Something that makes a human excited.

Undoubtedly there are a few positive characters who are able to “rise above” their environment, who are able to impress the people with whom they come in contact in spite of their clothes.
Sometimes we read of some learned woman, who has “made good in her profession,” who says that she has not looked in a mirror for years; but such a woman is a rare exception, and one is not safe in gambling with one’s chances of success by following her. It is not the positive characters with whom we are concerned, however, for they are few and somehow manage to take care of themselves. The vast majority of the race are not so blessed, and we need to observe but little to realize that with them the reaction of clothes is an important factor.
School girls should know that clothes may make a career; happiness and leadership in all the years of high school and college life may be affected by the story a Freshman’s clothes tell. Many a girl with a keen mind, who has a natural disregard for clothes, perhaps, or who has not been trained in the appreciation of beauty in clothes, has lost her opportunities for leadership and self-expression which by right her brain power should have given her.
One of the mental capacities which we all exercise and yet exercise most unconsciously is that of passing judgment on the people we meet. In a majority of cases the judgment is superficial and inaccurate; but the estimate is made. Some people may not get their final judgment till they hear one talk and will judge one by the tone of voice and by what is said as the true index; but the vast majority will form an opinion based largely, if not entirely, on appearance. One tells the world daily of one’s ideals, ambitions or good breeding through dress; and it is told so plainly that “he who runs may read” and, perhaps, he who reads may run.

A．care about their appearances

B．understand the art of dressing themselves

C．can catch others’ attention by dressing plainly

D．are able to dress properly without professional directions

Who is the text intended for?

D．necessary

Which of the following can be the best title?

A．Rise Above Your Environment

B．He Who Runs May Read

C．Dress to Impress

D．Art of Dressing

Maybe it is true that we do not know what we have got until we lose it, but it is also true that we do not know what we have been missing until it arrives．
It takes an hour to like someone, and a day to love someone, but it takes a lifetime to forget someone．Giving someone all your love is never an assurance that they will love you back．Do not expect love in return; but if it does not, be content it has grown in yours．Do not rely on one’s appearance; it can trick you．Do not rely on wealth; even that fades away．Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright．
There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them．Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do．
The brightest future will always be based on a forgotten past．You cannot go on well in life until you let your past failures and heartaches go off．May you have enough happiness to make you sweet, enough trails to make you strong, enough sorrow to keep you human, enough hope to make you happy．The happiest of people do not necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those appreciate the importance of people who have touched their lives．Always put yourself in others’ shoes．If you feel that it hurts you, it probably hurts the other person, too．
When you were born, you were crying and everyone around you was smiling．Live your life so that when you die, you are the one who is smiling and everyone around you is crying．
