19、m, Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialist Sandra Magnus make up the last crew to fly aboard a NASA space shuttle. All members of this Atlantis crew have flown on space shuttles before. But this time it is different, because NASA is retiring the shuttle fleet at the end of
20、 this mission. The astronauts readied for this mission with ascent training in a simulator, water survival training, running through emergency scenarios such as a fake fire on a mock-up of the space station, preparing in virtual reality labs and more simulators, reviewing the tools they might need i
21、n space and practicing post-landing exits from a mock-up of the shuttle. The crew says it is ready for this final mission. This last shuttle flight will help to restock the International Space Station. Although NASA is retiring its shuttle fleet, the United States has committed to funding the space
22、station through 2020. The orbiting lab is as capable as it is today because of the shuttle program.

26、类 4 【正确答案】 D 【知识模块】 科学类 5 【听力原文】 Experts say that automatic face recognition systems, in which a computer attempts to recognize an individual by checking his or her face against thousands of images stored in a database, are gaining in popularity, but are not very reliable. There wont be a match if t
27、he persons face is not contained in the database, or a match may be overlooked if a picture that is in the database looks sufficiently different than the individual standing in front of the systems electronic eye. Experts say thats because the stored photograph may be several years old and bear litt
28、le resemblance to the individual, or the pose or light may be different. Psychologist Rob Jenkins of the University of Glascow and his colleague Mike Burton believe they solved the problem. They randomly gathered 20 images of 25 famous male celebrities on the Internet and fed the photos into a face
29、recognition system that had a database of 31-thousand photos of famous faces. The recognition system accurately identified the individuals, about half of the time. 5 【正确答案】 D 【知识模块】 科学类 6 【正确答案】 A 【知识模块】 科学类 7 【听力原文】 Each year, scientists work to develop a unique influenza vaccine to protect people
30、against the strain expected in the coming flu season. Mutations in the virus mean that last years vaccine probably wont protect against this years flu variety. Now, a team of US scientists think theyre on track to developing a “universal“ vaccine that will protect people against all kinds of influen
31、za. The standard flu vaccine causes the body to produces antibodies, which target parts of the virus that frequently mutate. But in a new study, researchers used a vaccine aimed at a different part of the virus. Gary Nabel heads the US government s Vaccine Research Center at the National Institute o
32、f Allergy and Infectious Diseases of the National Institutes of Health and was the studys lead author, “There are parts of the flu virus that could be the target of what we would hope eventually could be a universal influenza vaccine. They dont mutate, and the reason they dont mutate is that if they
33、 try to. the virus cant survive if you have mutations in these sites.“ To get at these non-mutating parts of the virus, Nabel and his colleagues used a two-step vaccination process, called “prime-boost.“ The first step uses a bit of influenza DNA to get the patients immune system to begin fighting o
34、ff the flu, and then the protection is given a “boost“ some time later by the second step, which can be either another bit of DNA or a conventional flu vaccine. Preliminary phase one tests of this new type of flu vaccine have already started in humans, but in an interview via Skype, Nabel said that
35、even if all goes well, it will still be years before a universal flu vaccine is widely available. Gary Nabel of the US Vaccine Research Center points out that his universal flu vaccine would have another benefit. A DNA-based vaccine wouldnt have to be grown in chicken eggs, doing away with the time-
36、consuming and finicky manufacturing process of the current flu vaccine. 7 【正确答案】 B 【知识模块】 科学类 8 【正确答案】 A 【知识模块】 科学类 9 【听力原文】 Scientists have identified a new way of fighting cancer that limits the growth and spread of a variety of tumors in laboratory animals. When you get a cut, the area quickly be
37、comes inflamed swollen, red, and tender as the bodys immune system sends white blood cells to fight infection and heal the wound. The immune system reacts to many cancers in much the same way, says University of California, San Diego researcher Judith Varner. That happens when the immune system cell
38、s are hijacked by the tumor in a way that fosters the growth and spread of tumors. Varner and her colleagues identified a specific enzyme called PI-3 kinase gamma that allows the immune cells to get into the tumor, where it can be compromised. They figured out how to block PI-3 kinase gamma, using e
39、ither drugs or genetic methods, in laboratory mice. In addition to the mice with breast cancer, the researchers also used this approach on a variety of other cancers in laboratory animals and found it was consistently effective across a range of different kinds of tumors. Varner says suppressing PI-
40、3 kinase gamma might in theory also be effective to reduce the risk of cancer in the first place, in cases where chronic inflammation contributes to tumor formation. She says human testing of PI-3 kinase gamma inhibitors to battle cancer could begin as soon as a year or so from now. 9 【正确答案】 A 【知识模块

Taking these kinds of inventories is critical, they say, because habitats are disappearing. A botanist at Londons Royal Botanic Gard

The project is being conducted in close collaboration with Mozambican research institutes. Timberlake says taking stock of the country s biodiversity is critical because Moza

Next year, scientists will also take stock of the marine biodiversity in previously unexplored areas of Madagascar. The two projects are part of a massive, 10-year enterprise dubbed “O

46、like arthritis, says there is no significant gender gap in Indonesia, at least not in her field. Yanti, who like many Indonesians uses one name, is a researcher and lecturer in biotechnology at Atma Jaya University in Jakarta. So is Noryawati Mulyono, who is developing a new type of biodegradable pl
47、astic. She says today there are more opportunities for women to compete with men in the field of science. While the United Nations credits Indonesia with near gender parity in the field of science, overall in Asia women only constitute 18 percent of researchers. And despite parity in some fields, In
48、donesia still has a gender gap in the overall literacy rate. Poverty plays a large part in that situation, by keeping many girls out of school, although Indonesia has always valued education for girls as well as boys. Education advocates say in a world where technological innovation is key to develo
49、pment, a gender gap in science can put countries at a competitive disadvantage. Both Yanti and Mulyono recently received fellowships for their research from the cosmetic company LOreal. The awards are given to support gender equality in science. Both women are passionate about their work. Mulyono prefers to spend her vacation, or refreshing time as she calls it, collecting new samples of damar, a substance found in certain trees in Indonesia that she uses in her research. Yanti says the most rewarding aspect of being a scientist
