阅读理解When a new movement in art attains a certain fashion, it is advisable to find out what its advocates are aiming at, for, however farfetched and unreasonable their principles may seem today, it is possible that in years to come they may be regarded as normal. With regard to Futurist poetry, however, the case is rather difficult, for whatever Futurist poetry may be--even admitting that the theory on which it is based may be right--it can hardly be classed as Literature. 　　This, in brief, is what the Futurist says: for a century, past conditions of life have been conditionally speeding up, till now we live in a world of noise and violence and speed. Consequently, our feelings, thoughts and emotions have undergone a corresponding change. This speeding up of life, says the Futurist, requires a new form of expression. We must speed up our literature too, if we want to interpret modern stress. We must pour out a large stream of essential words, unhampered by stops, or qualifying adjectives, or finite verbs. Instead of describing sounds we must make up words that imitate them ;we must use many sizes of type and different colored inks on the same page, and shorten or lengthen words at will. 　　Certainly their descriptions of battles are confused. But it is a little upsetting to read in the explanatory notes that a certain line describes a fight between a Turkish and a Bulgarian officer on a bridge off which they both fall into the river--and then to find that the line consists of the noise of their falling and the weights of the officers: "Pluff! Pluff! A hundred and eighty-five kilograms." 　　This, though it fulfills the laws and requirements of Futurist poetry, can hardly be classed as Literature. All the same, no thinking man can refuse to accept their first proposition: that a great change in our emotional life calls for a change of expression. The whole question is really this: have we essentially changed?

阅读理解 The American Society of Clinical Oncology wrapped its annual conference this week, going through the usual motions of presenting a lot of drugs that offer some added quality or extension of life to those suffering from a variety of as-yet incurable diseases. But buried deep in an AP story are a couple of promising headlines that seems worthy of more thorough review, including one treatment study where 100 percent of patients saw their cancer diminish by half. First of all, it seems pharmaceutical companies are moving away from the main cost-effective one-size-fits-all approach to drug development and embracing the long cancer treatments, engineering drugs that only work for a small percentage of patients but work very effectively within that group. Pfizer announced that one such drug it's pushing into late-stage testing is target for 4% of lung cancer patients. But more than 90% of that tiny cohort responded to the drug initial tests, and 9 out of ten is getting pretty close to the ideal ten out of ten. By gearing toward more boutique treatments rather than broad umbrella pharmaceuticals that try to fit for everyone it seems cancer researchers are making some headway. But how can we close the gap on that remaining ten percent? Ask Takeda Pharmaceutical and Celgene, two drug makers who put aside competitive interests to test a novel combination of their treatments. In a test of 66 patients with the blood disease multiple myeloma, a full 100 percent of the subjects saw their cancer reduced by half. Needless to say, a 100 percent response to a cancer drug (or in this case a drug cocktail) is more or less unheard of. Moreover, this combination never would've been two competing companies hadn't sat down and put their heads together. Are there more potentially effective drug combos out there separated by competitive interest and proprietary information? Who's to say, but it seems like with the amount of money and research being pumped into cancer drug development, the outcome pretty good. And if researchers can start pushing more of their response numbers toward 100 percent, we can more easily start talking about oncology's favorite four-letter word: cure.

阅读理解Passage 3It was the summer of 1965. De Luca, then 17, visited Peter Buck, a family frienD、Buck asked De Luca about his plans for the future. “I’m going to college, but I need a way to pay for it,” De Luca recalls saying, Buck said, “You should open a sandwich shop.”That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1, 000. De Luca rented a storefront (店面) in Connecticut, and when they couldn’t cover their start-up costs, Buck gave another $1,000.But business didn't go smoothly as they expected De Luca says, “After six months, we were doing poorly, but we didn't know how badly, because we didn't have any financial controls”. All he and Buck knew was that their sales were lower than their costs.De Luca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They ’ d meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, “We are so successful: we are opening a second store.” And they did in the spring off 1966. Still, it was a lot of learning by trial and error.But the partners’ learn-as-you-go approach turned out to be their greatest strength. Every Friday,De Luca would drive around and hand-deliver the checks to pay their suppliers. "I drove probably two and a half hours and it wasn't necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out,” De Luca says.And having a goal was also important. “There are so many problems that can get you down.You just have to keep working toward your goal,” Deluca adds.Deluca ended up founding Subway Sandwich, the multimillion-dollar chain restaurant.Deluca opened the first sandwich shop in order to __________.

阅读理解Directions: In this part for the test, there will be 5 passages for you to read. Each passage is followed by 4 questions or unfinished statement, and each question or unfinished statement is followed by four choices marked A, B, C and D. You are to decide on the best choice by blackening the corresponding letter on the ANSWER SHEET.Passage Two Researchers have created male mice with no trace of a Y chromosome, supposedly the defining hallmark of being male.Reproductive biologist Monika Ward of University of Hawaii in Honolulu and colleagues started with mice that have only one X chromosome ( and no second sex chromosome). Normally those animals would develop as females. But when the researchers manipulated genes found on the X and another chromosome, the mice became males that could produce immature sperm. Those engineered males fathered offspring with reproductive assistance from the researchers, who injected the immature sperm into eggs, Ward and colleagues report in the Jan. 29 Science.The experiments demonstrate that there are multiple ways to make males, says Richard Behringer, a developmental geneticist at MD Anderson Cancer Center in Houston. “They’ve done it without any Y chromosome gene information,” he says “There’s not even a sniff of the Y around. ”At first glance, the experiments would seem to suggest Y chromosomes aren’t necessary for reproduction, which hints that evolution may eventually show Y’s the door. “To me it is a paradigm of the decline and fall of the Y chromosome，” says reproductive biologist Jennifer Marshall Graves of La Trobe University in Melbourne, Australia.But Ward and other researchers say the Y isn’t going anywhere and that interpreting the new results as the chromosome’s death knell is wrong. Because the Y-less males needed help to reproduce, “clearly we need the Y chromosome for full natural male reproduction，” says Mary Ann Handel, a reproductive biologist at the Jackson Laboratory in Bar Harbor, Maine.Ward and colleagues had previously shown that two chromosome genes一Sry and Eif2 s3y—are crucial for male mouse development. Sry is a master gene that turns on male developmental programming in early embryos. It turns on a gene called Sox9, which then sets off a biochemical chain reaction that leads to male development.But in the new experiments, the researchers turned on Sox9 through other means. Activating Sox9 in a genetically female embryo will cause it to develop as a male, Ward and colleagues found. But those males didn’t make sperm. “The testes were empty,” says Ward.In order to produce sperm, mice need the Eif2s3y gene, the researchers had previously discovered. In the new experiment, the mice were missing the gene because they didn’t have Y chromosomes. So researchers substituted a similar gene from the X chromosome called Eif2s3x. Only one copy of the Y version is needed to make immature, tailless sperm, but it takes at least five copies of the X version to do the same thing. “ This indicates that the Y chromosome gene is the strong one,，’ says Ward.Her research suggests that the Y chromosome has optimized production from genes that are necessary for making males. Making just the right dose of male development factors is how the Y protects itself from evolutionary erasure, Ward says. “ Our work does not support that the Y chromosome will disappear. ’，Graves disagrees, Ward’s work is “a lovely example of how you can lose even a really important gene,” she says. At least two species of rodents have already jettisoned their Y chromosomes entirely. Primates, including humans, don’t have EiJSs3y genes on their Y chromosomes. The new work may help explain how primates get along without the gene, Graves suggests, and the research may “give us useful information about what happens at the end of the Y chromosome. ”
