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.”
小题1: The underlined word “awed” in the second paragraph is closest in meaning to ___.
| A．influenced | B．amazed | C．delighted | D．inspired |
| 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 it can change 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. |
| 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 |

Bruno Mottin of the French Museums" Center for Research and Restoration said that on very close examination of the painting it became clear that the Mona Lisa"s dress was covered in a thin transparent gauze veil.（透明面纱）
"This type of gauze dress was typical of the kind worn in early 16th century Italy by women who were pregnant or who had just given birth. This is something that had never been seen up to now because the painting was always judged to be dark and difficult to examine," he told a news conference.
"We can now say that this painting by Leonardo da Vinci was painted in memory of the birth of the second son of Mona Lisa, which helps us to date it more precisely to around 1503."The young woman with the ambiguous half smile has been identified as Lisa Gherardini, wife of Florentine merchant Francesco de Giocondo. She had five children.
"People always wrote that Mona Lisa had allowed her hair to hang freely over her shoulders. This greatly surprised historians because letting your hair hang freely during the Renaissance was typical of young girls and women of poor virtue (美德)," he said.
The team had hoped to discover more details about Leonardo’s painting techniques, which the artist used to create a hazy (朦胧的) effect. But scientist John Taylor said the team had been disappointed by the lack of brush stroke（笔触）detail on the painting.

| A．Mona Lisa ,the Mysterious Woman |
| B．Mona Lisa was a New Mother |
| C．Great Discovery in Painting |
| D．Leonardo’s Painting Technique |

In the 1980s, as many as 1 million elephants across Africa were killed for their ivory tusks. This continued until 1989, when the Convention on International Trade in Species (CITES) voted to ban all trade in ivory. With trade choked off, demand for ivory fell. Elephant populations slowly began to increase. However, this progress was short-lived.
According to the IUCN, 2011 saw the highest levels of poaching and illegal ivory trading in at least 16 years. Around 25,000 elephants were killed in Africa that year. Preliminary data from the IUCN shows even higher levels of illegal trade may have been reached in 2013. “With about 22,000 elephants illegally killed in 2012, we continue to face a critical situation,” said John E. Scanlon, CITES Secretary-General. “Current elephant poaching in Africa remains far too high, and could soon lead to local extinctions if the present killing rate continues.”
At the African Elephant Summit, key African states where elephants make their home agreed to develop a “zero-tolerance attitude” towards poaching. The deal calls for maximum sentences for poachers and hunters, and increased cooperation between affected states. Officials are determined to classifying wildlife trading as a serious crime — and to making sure that the people who commit it are punished. All participants at the conference agreed to sign the deal. With these states coming together, there may yet be hope for elephants. (293 words)

Since the world food crisis several years ago, researchers have directed more of their attention to small farms. Most farms in areas south of the Sahara Desert are only about one or two hectares. One of the goals is to increase production without necessarily clearing more land to grow additional crops.
American researchers say that can happen with greater use of an agricultural system called perennation. It mixes food crops with trees and perennial plants – those that return year after year.
Mr. Reganold, who is with Washington State University, says poor soil may have resulted from years of weathering that washed away many nutrients. He says some farmers may have done more harm than good.
He estimates that up to two billion dollars worth of nitrogen, phosphorous and potassium is lost from African soil each year.
The scientist says the word perennation defines three systems that are already used in Africa. The oldest of the three is called evergreen agriculture. This is where farmers plant trees with their crops. John Reganold says farmers in Africa have been doing this for sixty years, but it seems to be growing in popularity.
The method is gaining widespread use in countries such as Niger, Burkina Faso, Malawi and Zambia. The trees are planted among maize, millet or sorghum crops. They not only add nitrogen to the soil through their roots, but also through their leaves when they fall off and break down. At other times of the year, the trees can protect plants from strong sunlight.
Mr. Reganold was one of three researchers who wrote a report about perennation. It was published in the journal Nature.

Yin Weimin, minister of human resources and social security, demonstrated that we did not put a timetable on the move when he spoke about it during a forum at the weekend.
"Delaying the retirement age is a very complicated issue and we will study it according to the situations of population and employment and consider different groups of people," Yin said.
He noted that hikes in the retirement age have been brought in by many countries and can be a good way to deal with an aging population and ensure the healthy and stable development of social security.
The life expectancy of Chinese people is now 73 years and is expected to rise to 74 during the next five years, he said.
Nearly three out of 10 Chinese people will be older than 60 by 2040, according to a United Nations forecast.
The retirement age in China currently is 60 for men and 55 for female civil servants and 50 for female workers.
The idea of delaying the retirement age is being widely supported by government officials, while many laborers and non-government employees were less enthusiastic about the prospect of working for longer. Currently, they have to pay into their pension plans for at least 15 years before they can retire.
Chen Xianlian, a female worker at a motorcycle parts manufacturer in Chongqing municipality is among those who would like to see the retirement age left as it is. “I have to do lots of tough and repetitive work every day and I feel very tired after my working day,” the 41-year-old said. “All my colleagues are discussing the government"s possible move to lift the retirement age. None of us wants to work any extra years.”
University graduates also fear that any rise in the retirement age could limit their employment opportunities.

Pi, the lead character in Oscar-winning Ang Lee’s new movie Life of Pi, went through an inspiring journey of growth and self-discovery. So did 19-year-old Suraj Sharma, the Indian actor who plays him.
But it was a lucky chance that opened up the opportunity for the new star. Sharma was a regular student who lived with his mathematician parents in Delhi, India. As the director traveled to Mumbai to find his Pi, the teenager went along with his younger brother, who had acted in a couple of movies, to audition(试镜). But little did Sharma know that he would end up winning the role from 3, 000 hopefuls.
Lee said he saw Pi in Sharma: “Not only does he have a compelling and wise look. He has this rare talent.” The director said that in the final round, Sharma gave one of the “most compelling readings we had. In the end, he was in tears.” Understandably, Sharma didn’t want to let Lee down. “He (Lee) had given me this opportunity. I had to give it my best,” Sharma told the Philippine Daily Inquirer.
Sharma swam for four or five hours a day until he was completely comfortable with the water. He also worked on his body because he had to first gain weight and then quickly lose weight as the story developed. He even had rats run all over him to prepare for his role. Lee was impressed by the teenager, especially his endurance and patience in staying in a water tank for many hours each day. Sharma was only 16 when Lee signed him. After three years of shooting, Sharma said he had matured with Pi’s journey.
