【题目】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.

【1】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. Henry Lai wrote a lot of articles about this new study.

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

A. Because the scientists want to be sure of the accuracy of 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 that would be too noisy and bad for the experiment.

【3】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.

【4】According to the last two paragraphs, which is the safest way to use a cell phone?

A. Holding the cell phone close to your head.

B. Using a cell phone more than three hours a day.

C. Taking the most powerful cell phone.

D. Keeping the cell phone at a distance.

【5】Where is this article probably taken from?

A. Literature magazine. B. Science News.

C. Story books. D. Art Journal.

【题目】Everyone has done experiments in high school laboratories, but have you ever thought about designing a satellite to explore space?

On Nov. 19, a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record-setting. 28 other small ones on a rocket were sent from a NASA center in Virginia, CNN reported. It took the students seven years to build.

The students call their tiny satellite TJ3Sat, which is named after their school. It is just 10x10x12 centimeters and weighs only 0.89 kilograms, according to Orbital Sciences, a company which developed the rocket and supported the students’ project. It can be controlled with a smartphone.

Like most satellites, TJ3Sat can send and receive data. The small spacecraft is equipped with a voice synthesizer (合成器), which can switch text to voice and transmit those sounds back to Earth over radio waves, said Orbital officials. In this case, anyone can give it a try via the project’s website (school website) by submitting (提交) a text. The texts that get approved will be sent to the satellite, changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’ on our ground station and when it is on the other side of the world, in India, someone can hear ‘Go Colonials’over the radio,” the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time. Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs, the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities, Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro, program executive (主管) for small spacecraft technology at NASA, said in a statement. “I think we might be seeing kids saying what they want to do is build a spacecraft. The idea here is that they really can do that.”

【1】Which of the following statements about TJ3Sat is TRUE according to the article?

A.It took a group of students about a decade to build the satellite.

B.Besides TJ3Sat, 28 other small satellites were built by the students.

C.TJ3Sat can receive text messages that the students send into space, which can be changed to voice messages and broadcast back to Earth.

D.TJ3Sat is expected to stay in orbit for the next year, sending out messages together with information about its position in space.

【2】According to the article, the launch of the satellite _______.

A.is evidence of the advance of spacecraft technology

B.proves that hard-working teenagers can achieve a lot

C.shows the importance of extracurricular activities at school

D.has inspired many people to take an interest in space travel

【题目】Educating Girls Is a Real Lifesaver

Clare Short knows it. Every developing economist knows it. The World Bank knows it. The education of girls is the surest way to reduce poverty.

The reason is simple. All the evidence shows that taking girls out of the fields and homes, and putting them behind desks, raises economic productivity, lowers infant and maternal(产妇) death rates, reduces birth rates, and improves environmental management.

Why, then, are 90 million primary school-age girls around the world not in school? For the same reason that when Charles Dickens was writing David Copperfield 150 years ago girls were absent from the British education system: Men in power mostly prefer it that way, or are not interested enough in changing the situation to commit energy and money to doing so.

The countries with the poorest record for having women in positions of power or influence have the worst figures for girls’ education. High-profile intervention(介入) by organizations such as the World Bank has begun successfully with several countries, and more of the same will probably be needed to bring change in conservative, male-run states.

Even if there were no development payoff from gender equality in schools, the education of girls would still be a cause worth fighting for. Education is a human right, and the denial of it to girls is a scar on the community in the twenty-first century.

To be born a girl in a rural area in Nepal, Pakistan, Indonesia, Morocco, Togo, or Sudan — half a dozen of the most shameful performers — means being condemned to a life without school, education, or clean water, marriage and babies coming too early, too many births, children who die of preventable diseases, backbreaking work in the fields, subordination(从属) to husband and his family, and an early death.

Every year, almost 12 million children under the age of five needlessly die of infectious diseases associated with poverty. But each additional year spent by their mothers in primary school lowers the risk of premature child deaths by about 8 percent. In Pakistan, an extra year of school for 1,000 girls could prevent sixty infant deaths.

With women and girls being the main farmers in Africa and southern Asia, their education offers a chance to develop more efficient farming practices, improve output, and raise awareness of the ecological needs of the land with tree planting and farming. Therefore, the world community cannot afford to ignore this avenue of change.

【1】Which is Not the reason why educating girls reduces poverty?

A. It improves environmental management.

B. It raises economic productivity.

C. It creates more children.

D. It lowers maternal death rates.

【2】What does the underlined word “it” in Paragraph 3 refer to?

A. The poor economy at that time.

B. Girls’ absence from school.

C. Energy and money.

D. The education of girls.

【3】Which of the following is TRUE according to the passage?

A. The countries where women have great influence and are in power always do worse in girls’ education.

B. Some organizations such as the World Bank haven’t taken the lead in girls’ education.

C. Some girls in Sudan and Indonesia are bound to live a life without education when they are born.

D. Each extra year of school for girls has nothing to do with the birthrate and maternal deaths.

【4】How many more infants will survive when 100 girls stay in school for another year?

A. 5 B. 6 C. 8 D. 12

【5】What does the author think of girls’ education?

A. essential B. terrible

C. indifferent D. helpless
