The low percentage of women in science ，technology，engineering，and mathematics(STEM) careers is often attributed (归因于) to men being believed to be better at the sort of thinking those fields require. Though studies have debunked the view,they have largely been based on results acquired from various several standardized tests. Now, researchers from Pennsylvania' S Carnegie Mellon University have found evidence that is hard to overlook; MRI (磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems.
The groundbreaking study to evaluate the biological gender differences in the math talent of young children was led by the university' s professor of neuroscience, Jessica Cantlon. For their study ,the team selected 104 young children, between 3 and 10 years old, divided almost equally by gender. The scientists used a functional MRI to observe their brain activity as they engaged in math tasks. These included watching age appropriate educational videos and doing math exercises such as counting and addition,as well as reading for comparison.
“We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non math content like reading or the alphabet, Cantlon said.“When we do that in lite girls, we see a particular network of the brain respond,and when we do that same analysis in boys, we see the exact same regions.”
So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions. Previous studies have indicated that parents tend to spend more time with young boys in play that inspire spatial cognition (空间认知)-such as toys that involve learning number skills and shapes and solving puzzles. Educators were also observed to spend more time with boys during math class.
1.What does the underlined word“debunked” in paragraph 1 mean?
A.Disproved. B.Supported.
C.Confirmed. D.Overlooked.
2.What does paragraph 2 mainly focus on?
A.The purpose of the research.

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
1.What does "these two killers" in the second paragraph refer to?
A.Gene technology and another treatment of the two diseases.
B.The two murderers who killed the cloned baby
C.The two diseases of cancer and heart disease
D.Hereditary diseases and cancer
2.What’s the main idea of the third paragraph?
A.How gene technology can be applied in the field of treating hereditary diseases.
B.Gene technology can be used to clone human babies.
C.Gene technology can help people to give birth of a baby.
D.Gene technology can help the English imperial family out
3.In what way gene technology can help to treat hereditary diseases?
A.Using gene technology, people with hereditary diseases can have more living days.
B.Using gene technology, scientist finds the wrong gene and corrects it.
C.Using gene technology, human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
4.What is the main purpose of writing this passage?
A.Expressing the writer’s idea that gene technology will benefit people
B.Telling people the advantages of gene technology
C.Telling the readers that gene technology will not benefit people
D.Explaining that gene technology will also do harm to the humanity

Will Nanfang University of Science and Technology in Shenzhen announce a new beginning for China’s higher education reform? It’s too early to answer.But its presence is challenging the Ministry of Education.Even without the approval of the ministry it seems that the school is determined to move forward and enroll 50 students, so-called child prodigies(奇才), to begin classes on March l, 2011.On graduating in 2015, these students will receive a diploma unauthorized by the Ministry of Education-unlike the students of their age from the state-run universities.
The school is committed to modeling itself on Hong Kong University of Science and Technology, but if the government will not approve the school, the situation could cause a lot of trouble for those 50 students if they want to do graduate studies at other higher learning institutions.Other schools could turn their applications down for their unauthorized diplomas.
The difficulties, however, have not frightened students and their parents away.On Dec.18, 2010 more than 1,000 students and their parents visited Nanfang University of Science and Technology for interviews.
Private investment marks the school out from other higher learning institutions in the nation.Not a penny comes from the government. So the government will have no voice in how the school will be run.
The Ministry of Education has published a comprehensive plan for education reform and development between 2011 and 2020.The goal is to make China’s higher education internationally competitive.To accomplish this goal, the government should have the courage to let the educators who have big ideas try them out.The ministry should have applauded the independence the school in Shenzhen has shown and encouraged more to do likewise.
Education reform in China has reached a new and crucial stage.Nanfang University of Science and Technology has a long way to go to prove itself competitive rather than a diploma mill.
1.Over 1,000 students and parents visited the school because________.
A．they believe that the school will have a bright future
B．they believe the government is sure to approve the school

A．It is another kind of diploma mill.
B．It’s impossible for the school to be competitive.
C．It will never get the approval from the Ministry of Education.
D．Its independence from the government may benefit the education reform.
