Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice．However, few people know that she was also the mother of a Nobel Prize winner．
Born in September, 1897, Irene Curie was the first of the Curies’ two daughters．Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers．She finished her high school education at the College of Sévigné in Paris．
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics．When World War I began, Irene went to help her mother, who was using X-ray facilities（设备）to help save the lives of wounded soldiers．Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium．Her services were recognized in the form of a Military’s Medal by the French government．
In 1918, Irene became her mother’s assistant at the Curie Institute．In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work．They soon fell in love and were married in 1926．Their daughter Helene was born in 1927 and their son Pierre five years later．
Like her mother, Irene combined family and career．Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935．Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）．Irene Joliot-Curie died from leukemia on March 17, 1956．Why was Irene Curie awarded a Military Medal?
| A．Because she received a degree in mathematics． |
| B．Because she contributed to saving the wounded． |
| C．Because she won the Nobel Prize with Frederic． |

In which of the following aspects was Irene Curie different from her mother?

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world．They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly — somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed．So far the time being, black hole must remain a mystery.
Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal (处理) in the sky!When the star begins to die ______.
| A．there is no fuel left in it | B．its outer layer goes into space first |

Perhaps the most astonishing theory to come out of kinetics, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed．In other words, we learn our looks; we are not born with them.
A baby has generally unformed facial features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around family and friends. This helps explain why the people of some regions of the United States look so much alike. New Englanders or Southerners have certain common facial characteristics that cannot be explained by genetics (遗传学) “The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after permanent (永久的) teeth are set. For many, this can be well into adolescence (青春期). A husband and wife together for a long time often come to look somewhat alike. We learn our looks from those around us. This is perhaps why in a single country there are areas where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many Southerners find cities such as New York cold and unfriendly, Partly because people on Madison Avenue smile less than people on Peach Tree Street in Atlanta, Georgia．People in densely (稠密地) populated urban areas also tend to smile and greet each other in public less than people in rural areas and small towns. Ray Birdwhistell believes that physical appearance ______.
| A．has little to do with culture | B．can be influenced by culture |
| C．is decided by culture | D．varies from place to place |
Ray Birdwhistell can tell what region of the United States a person is from by ______.
| A．how much he or she laughs | B．how he or she raises his or her eyebrows |

The UN Security Council was created in 1945. It is made up of 10 rotating (轮值的) members and five permanent members, which have a veto, the power to stop a resolution (决议). Most UN members now consider the organization's structure outdated． But any changes need the agreement of two-thirds of the 191 members, and no veto from any of the five permanent council members.
Last year, Japan, Germany, Brazil and India formed a lobbying (游说) group to get permanent council seats. But North and South Korea have doubts about Japan, Italy opposes Germany for a seat, Pakistan is against India's candidacy (候选资格) and Mexico and Argentina frown on Brazil.
A wave of emotion swept through China last week as millions voiced their opposition to Japan's permanent membership of the United Nations (UN) Security Council. By last Friday over 22 million Chinese had signed an online petition (请愿) against Japan's bid for a permanent seat on the council.
According to major Chinese websites, such as sina.com, more than 170,000 overseas Chinese also signed． This is the first online activity of its kind．
The petition was started by US-based Alliance for Preserving the Truth of the Sino-Japanese War (抗日战争史实维护会). They want Japan to apologize for crimes during World War II. The group also plans to present the petition to the UN this autumn.
Chinese Foreign Ministry spokesman Liu Jianchao said he didn't think the petition shows anti-Japanese feeling. He believed instead it is a request for Japan to take a responsible attitude towards history.What’s the main idea of the first paragraph?
