Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there’s one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office.

If that isn’t enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine’s Young Amazing Women of the Year.

After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student though, her scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically.

Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing.

Bose chose to study a protein (蛋白质) and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again.

“My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin,” Bose said.

Bose’s achievements aren’t limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper.

Bose is currently getting practical experience at the National Institute of Health and she’ll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor.

The reason why women love to spend hours in shops while men prefer to be in and out of the high street in minutes can trace back(追溯) to their hunter-gathering past, find scientists.

While women spent their days gathering food, often with children, men were hunters who made plans about how to catch and kill their prey (猎物). These two ways of getting food in the past show how we shop in modern times, the study believes.

Women would spend hours trying to find the right things, because they had in the past spent ages trying to find the best quality and health-giving food. Men, on the other hand, decided in advance what animal they wanted to kill and then went looking for it. Once it was found and killed, they returned home.

Daniel Kruger, professor of the University of Michigan, said the study could be the answer to why there are a lot of collisions when couples go shopping together. He said it could also help couples to avoid fights in the shops if they understood the reasons why each sex had different ways of deciding on the perfect present.

“In modern times, women are much more likely than men to know when a specific type of item will go on sale. Women also spend much more time choosing the perfect color and texture.”

Professor Kruger said his study was important because if men and women understood each other’s shopping habits they could avoid arguments while shopping.

1.What has decided the different shopping habits of men and women?

A. Different ways of keeping food in the past.

B. Different ways of eating in the past.

C. Different ways of buying food in the past.

2.In comparison(比较) with men, women were less likely to_____.

A. catch the right animal and kill it.

B. spend much time on shopping.

C. choose the right color and texture.

D. know when a specific item was on sale.

3.What does the underlined word mean in the fourth paragraph?

A. Requests B. Arguments.

C. Concerns. D. Differences.

4.According to Kruger, his study can help to _____.

A. develop good shopping habits.

B. avoid arguments in shopping between men and women.

C. give people tips on choosing good gifts.

D. make sure people buy safe food for children.

While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!

About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” — a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.

Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

1.Why does the author mention the things that astronauts in space cannot do?

A. To ask us not to take common things for granted.

B. To show they live a difficult life there.

C. To show their life is boring in space.

D. To introduce the topic of the text.

2.NASA offered $ 125, 000 to Anjan Contractor mainly to _______.

A. create some new type of 3-D printer

B. attract more companies to work for NASA

C. help astronauts in space enjoy fresh pizza one day

D. produce pizza in large quantities to earn great profits

3.The biggest challenge that Anjan Contractor is faced with now is probably that _______.

A. he has no money left to go on with his research

B. the pizza doesn’t seem appetizing to pizza lovers

C. he has no way to make pizza that can last for thirty years

D. he cannot make the food container last for decades

4.What’s the best title of the passage?

A. NASA is trying its best to help astronauts eat better

B. Astronauts may soon be able to enjoy steaming hot pizza

C. NASA is working on making pizza for common people

D. A 3-D pizza printer has been used to make pizza
