Researchers have created a backpack that has a computer and medicines in it that can help even untrained soldiers save the lives of wounded troops. Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends.

Doctors and engineers have developed what they call an “intelligent backpack”.It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to give to injured troops.

About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The U. S. Department of Defense has given money to the project.

Ron Poropatich leads the project. He is a retired army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a person^ heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung.

The intelligent backpack's computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to use to save the soldier’s life.

Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield.So,Dr. Poropatich says, the researchers hope to create a backpack that will have devices .that can keep a .soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing animals in about three years.

1.What can we learn from the first paragraph?

A. The backpack can play a big part in the battlefield.

B. Most of the soldiers can’t use the backpack correctly.

C. Soldiers should have taken medical training.

D. War or battle has brought harm to the world.

D. The devices can adjust soldiers’ blood pressure.

I don’t ever want to talk about being a woman scientist again. There was a time in my life when people kept asking me stories about what it’s like to work in a field under the control of men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the existence of the universe, the shape of space time and the nature of black holes.

At 19, when I began studying astrophysics(天體物理學(xué)), 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 problem started to bother me. My every achievement—jobs, research papers, awards—was viewed from the angle of gender (性別) politics. So were my failures.

Then one day a few years ago, out of my mouth came a sentence that would finally become my reply to any and all provocations(挑釁): I don’t talk about that any more. 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 problems. Why should removing 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 take no notice of those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the scene of their physics professor heavily pregnant (懷孕）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.

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

A. She feels unhappy working in the scientific field.

B. She finds space research more important.

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

D. She is tired of the sexism in scientific field.

2.From Paragraph 2, we can infer that people would think the author’s failures were due to __.

A. her over-confidence as a female astrophysicist

B. her involvement in gender politics

C. the very fact that she is a woman

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

3.Why does the author feel great satisfaction when talking about her class?

A. Female students no longer have to bother about gender issues.

B. Her students’ performance has brought back her confidence.

C. More female students are going in for science than before.

D. Her female students can do just as well as male students.

4.What does the image(形象) that the author presents to her students suggest?

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

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

C. Women students needn’t have the concerns of her generation.

D. Women now have fewer problems going in for a science career.

Single-sex schools are better than mixed schools

Message 1 — posted by Jane, Amsterdam

I think mixed-sex schools are the only way for children to learn, because it's natural. In higher education and their working life, they will be mixed so it makes sense for them to be mixed at school. School should reflect the real world.

Message 2 — posted by Hans, Germany

My reaction to this is very clear. For me, single-sex schools are much better, and the statistics show that they get better exam results, particularly at secondary level. Anything which helps children pass exams must be a good thing.

Message 3 — posted by Bill, USA

Boys and girls learn in very different ways. I feel that they should be educated separately so teachers can focus on their different needs. The way I see it is that if you have a zoo, you don't put the lions in with the zebras!

Message 4 — posted by Martin, London

My view on this is that it doesn't really matter. What is important is the curriculum (課程), and keeping students interested. I was a teacher and we had a lot of truancy (逃學(xué)) to deal with, and problems with students missing lessons because they found them boring. Never have a timetable with Maths as the first class on Monday morning!

Message 5 — posted by Emily, Sydney

I don't think there is any question that mixed schools are better. There is too much competition at single-sex schools, which often means that students don't make enough progress. I also think there is more bullying (欺凌) at single-sex schools, where children are picked on because of the increased competition. Single-sex schools lead to a “dog eat dog” situation.

1.What is Jane's attitude towards single-sex schools?

A. Favorable. B. Negative. C. Objective. D. Unconcerned.

2.Both Hans and Bill hold that _____.

A. teachers should meet students' different needs

B. boys and girls should be taught separately

C. schools should focus on students' exam results

D. mixed schools are better than single-sex schools

3.Martin stresses the importance of _____.

A. exciting students' interest in courses B. students' time awareness

C. training students to obey rules D. school management

4.Emily uses “dog eat dog” to show _____.

A. her support for single-sex schools

B. students' determined effort to succeed

C. the fierce competition in single-sex schools

D. the better education results in single-sex schools
