suitable for a family of fivebafter my pubic lectures on evolution, someone in the audience asks. “are we still evolving?” people want to know if humans are getting taller, smarter, better looking or more athletic. my answer is truthful but disappointing: were almost certainly evolving, but we dont know in what direction or how fast.weve seen some evolution in our species over the past few millennia(千年), but it was detected by reconstructing history from dna sequences. for example, we know that during the past 10,000 years, several populations of humans those keeping sheep, cows or goats for milk gained the ability to digest dairy products. this trait was useless in our earlier ancestors who, after babyhood, never encountered milk. and in the past 3,000 years, tibetans have acquired genetic adaptations that allowed them to develop well in their high-altitude. low-oxygen home. but these well-documented changes are limited to particular populations, so the evidence for recent evolution of our entire species, remains not much.the authors of “evolving ourselves” disagree. not only, they claim, are we evolving faster than ever, but were doing it to ourselves. juan enriquez and steve gullans argue that humans have controlled evolution not just in our own species but virtually in all species: “for better or worse, we are increasingly in charge. we are the primary drivers of change. we will directly and indirectly determine what lives, what dies, where, and when. we are in a different phase of evolution: the future of life is now in our hands.”according to the authors, weve replaced natural selection with what they call “unnatural selection.” overfishing, for example, has reduced the average size of many fish species, for taking the biggest fish selects in favor of those that reproduce when younger and smaller.yet while theres no doubt that were changing the planet, the claim that were completely changing evolution on the planet does not follow. lets take those fish that are evolving to reproduce smaller and younger. this phenomenon has been documented in many species that we eat, but this is just a minuscule fraction (极小的一部分) of the 30,000 known species of fish.the authors speak with unwarranted assurance about how our species is evolving in response to nearly everything. when they assert, for example, our ingestion (摄取) of drugs and exposure to chemicals mean that “our childrens brains are evolving fast,” they are overplaying their hand and abusing the word “evolution.” out childrens brains may be changing fast in response to the new pharmacological (药理学的) environment, but change alone is not evolution.58. the two examples in paragraph 2 are given to .a. show in what direction humans evolveb. explain the importance of dna sequencesc. illustrate the evidence for evolution of our entire species is insufficientd. demonstrate how slow humans have evolved over the past few millennia59. the authors of “evolving ourselves” claim that .a. humans dominate the future of other lifeb. fish become smaller because of natural selectionc. humans are to blame for changing the planet for the worsed. the boundary between natural selection and unnatural selection is unfixed60. what is the major question discussed in the passage?a. are humans still evolving?b. is unnatural selection powerful?c. are humans the main driver of evolution?d. does evolution require many genetic changes?camericas businesses are getting older and fatter, while many new businesses are dying in infancy.a study last month by the brookings institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. in addition, young people are starting companies at a sharply lower rate than in the past.a new report from the national association of manufacturers shows a major cause: the cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the gdp, and this cost falls disproportionately on smaller, newer businesses.its risky, difficult and expensive to start a business, and getting more so. governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in california, compulsory paid sick days for even hourly employees. these regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.this is partly an unintended issue of resources-established companies can cope with new costs more easilybut its also deliberate. for instance, big insurance companies got a seat at the table to help write obamacare, but less politically powerful firmslike medical device manufacturers-got squeezed.mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. they are also more likely to want to protect steady revenue streams than revolutionize their industry.major companies that have been so ill-managed they would otherwise collapse-airlines, car companies and banksstagger (蹒跚) on because politicians ride to the rescue with bags of taxpayer money.the genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. as such, the rise of a well-connected oligarchy (寡头政治) that protects big business at the expense of small business, and the established over the new, is opposite to american ideals.income inequalitywhich is directly caused by faulty government policyis being promoted as the reason to impose more of that bad policy. but lets be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.politics is, and always has been, about balancing competing interests seeking to benefit themselves, and thats as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies (垄断) by harming the consumer, the taxpayer and the economy. policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.61. we can learn from the passage that .a. over several decades, new companies have grown steadily.b. mature, successful corporations prefer to maintain their stable incomes.c. less politically powerful firms also have their voice in making regulations.d. the cost of obeying government regulations falls equally on all businesses.62. we can infer from the last three paragraphs that .a. the rise of a well-connected oligarchy is contrary to american idealsb. the state economy may depend on those innovative businessesc. income inequality is what the government should take action to resolved. the government picks winners and losers through the law of free market63. it can be concluded from the passage that .a. larger and older firms have a command of resources of various aspectsb. most of the ex-lawmakers work in mature, successful corporationsc. politicians like providing financial aids to the companies of worse operationd. big insurance companies have better relationship with obama64. as to the development of smaller businesses, the writer is .a. contentedb. confidentc. concernedd. convinceddthe phone id flashed, “emergency vet”. “oh no” i whispered. i could not lose merlin now.ron and i had tried to have children for a long time with depressing results. i threw myself into my work. any maternal feelings i had were spent on merlin.i couldnt wait to get home from work each night. i wanted to pick up that warm bundle of loving fur and nestle him. i wanted to sing “rock-a-bye merlin”, as i did every night as he would put his paws around my neck.merlin was my comfort especially at times when i wondered if god was listening. but last night something had changed. not only did i sing “rock-a-bye merlin”, but i asked, “what will i do after youre gone?”although merlin was 19 years old, a senior in the age of a cat, he didnt look or act that way. i didnt want to accept the fact that he was nearing the end of
