1、(A) Like an only child dreaming of lost siblings, we dream of finding other Earths, other creatures and civilizations out in space, or even other universes. We all want to find out that we are cosmic Anastasias and that there is a secret that connects us, that lays bare the essential unity of physical phenomena. And so we try, sometimes against great odds. The year that is now ending began with some areas of science in ruins. One section of the Large Hadron Collider looked like a train wreck with several-ton magnets lying about smashed after an electrical connection between them vaporized only nine days off a showy inauguration. The Hubble Space Telescope was limping about in orbit with only one of its cameras working. But here is the scorecard at the end of the year: in December, the newly refurbished collider produced a million proton collisions, including 50,000 at the record energy of 1.2 trillion electron volls per proton, before going silent for the holidays. CERN is on track to run it next year at three times that energy. The Hubble telescope after onelast astronaut servicing visit, reached to within spitting distance of the Big Bang andrecorded images of the most distant galaxies yet observed, which existed some 600 million or 700 million years after the putative beginning of time. Not to mention the rapidly expanding universe of extrasolar planets. In my view from the cosmic bleachers, the pot is bubbling for discovery. We all got a hint of just how crazy that might be in the new age of the Internet on Dec. 17, when physicists around the world found themselves glued to a Webcast of the results from an experiment called the Cryogenic Dark Maner Search. Rumors had swept the blogs and other outposts of scientific commentary that the experimenters were going to announce that they had finally delected the ethereal and mysterious dark matter particles, which, astronomers say, make up a quarter of the universe. In the end, the result was frustratingly vague and inconclusive. “We want it to be true—we so want to have a clue about dark matter,” Maria Spiropulu, a Caltech physicist working at CERN wrote to me the night of the Webcast. “And it is not easy,” Dr. Spiropulu said. “The experiments are not easy and the analysis is not easy. This is a tough, tough ride over all.” Although we might well solve part of the dark maner conundrum in the coming years, the larger mystery winds out in front of us like a train snaking into the fog.What is the passage primarily about?
A．The Hubble Space Telescope.
B．The essential unity of physical phenomena.

4、What is the attitude of the author toward the Webcast of the results from the Cryogenic Dark Matter Search?

B．Enthusiastic.
C．Critical.
D．Liberal.
5、The mystery of the dark matter will probably be solved_______.
A．in the coming years
B．next year

6、(B) Only one man seems to have ever been cured of AIDS, a patient who also had leukemia. To treat the leukemia, he received a bone marrow transplant in Berlin from a donor who, as luck would have it, was naturally immune to the AIDS virus. If that natural mutation could be mimicked in human blood cells, patients could be endowed with immunity to the deadly virus. But there is no effective way of making precise alterations in human DNA. That may be about to change, if a powerful new technique for editing the genetic text proves to be safe and effective. At the University of Pennsylvania, Dr. Carl June and colleagues have used the technique to disrupt a gene in patients’T cells, the type attacked by the AIDS virus. They have then infused those cells back into the body. A clinical trial is now under way to see if the treated cells will reconstitute a patient’s immune system and defeat the virus. The technique, which depends on natural agents called zinc lingers, may revive the lagging fortunes of gene therapy because it overcomes the inability to insert new genes at a chosen site. Other researchers plan to use the zinc finger technique to provide genetic treatments for diseases like bubble-boy disease, hemophilia and sickle-cell anemia. In principle, the zinc finger approach should work on almost any site on any chromosome of any plant or animal. If so, it would provide a general method for generating new crop plants, treating many human diseases, and even making inheritable changes in human sperm or eggs, should such interventions ever be regarded as ethically justifiable. Zinc fingers are essential components of proteins bused by living cells to turn genes on and off. Their name derives from the atom of zinc that holds two loops of protein together to form a “finger”. Because the fingers recognize specific sequences of DNA, they guide the control proteins to the exact site where their target gene begins. After many years of development, biologists have learned how to modify nature’s DNA recognition system into a general system for manipulating genes. Each natural zinc finger recognizes a set of three letters, or bases, on the DNA molecule. By stringing three or four fingers together, researchers can generate artificial proteins that match a particular site. The new system has been developed by a small biotech company, Sangamo BioSciences of Richmond, Calif., and, to some degree separately, by academic researchers who belong to the Zinc Finger Consortium. “We now have a full alphabet of zinc fingers,” Mr. Lanphicr, head of Sangamo, said, “but when we started the company it was like typing a novel with two fingers.” Zinc finger proteins have many potential uses. One is to link them to agents that turn on or turn off the gene at the site recognized by the fingers.The passage mainly discusses_______.
A．bone marrow transplant
B．the structure of DNA
C．a new way to edit DNA
D．how to mimic mutations in human DNA
7、Which of the following is NOT true about the zinc finger technique?

D．It will provide a general method for generating new crop plants and treating many human diseases.
8、Zinc fingers are essential to______.
A．making inheritable changes in human sperm or eggs
B．switching genes on and off
C．providing a general method for generating new crop plants
D．treating diseases like hemophilia and sickle-cell anemia
9、The zinc finger technique would probably involve______if it was effective on anychromosome of any plant or animal.
A．many clinical trials
B．interventions in DNA
C．moral issues
D．endorsement from the government
10、All of the following are true EXCEPT______.
A．that zinc fingers have a full alphabet
B．that the researchers were writers before they started the company
C．that Zinc finger proteins can be linked to agents that turn on or tum off the gene
D．that the fingers guide the control proteins to the exact site
