It was the development of that brain that drove the evolution of our early human (27) away from an apelike ancesto

But the question of just why and how we (28) such big brains, which consume 20 percent of our energy, has long bedeviled science.“A major difference in muscular strength between humans and nonhuman primates provide one possible (29) ,“ suggests a new study.
17、 The study, (30) Tuesday in the journal PLoS Biology, looked at how rapidly the metabolic needs of various organs, (31) our brains to our kidneys, have evolved. Some scientists have suggested that the rapidly evolving metabolism of the human gut, for example, drove the brains evolution. Instead, the

Over the same time period, the brain evolved four times faster than the rest of the body.（分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空

In December of 2012, three young men were living in a claustrophobic (患幽闭恐惧症的) apartment in San Francisco
27、s Tenderloin district, working on a technology startup. They had received a hundred and seventy thousand dollars from the incubator Y Combinator, but their projecta plan to make inexpensive cell-phone towershad failed. Down to their last seventy thousand dollars, they resolved to keep trying out new
28、 software ideas until they ran out of money. But how to make the funds last? Rent was a sunk cost. Since they were working frantically, they already had no social life. As they examined their budget, one big problem remained: food.B. They had been living mostly on ramen, corn dogs, and Costco frozen
29、 quesadillassupplemented by Vitamin C tablets, to stave off scurvy (坏血病)but the grocery bills were still adding up. Rob Rhinehart, one of the entrepreneurs, began to resent the fact that he had to eat at all. “Food was such a large burden,“ he told me recently. “It was also the time and the hassle.
30、We had a very small kitchen, and no dishwasher.“ He tried out his own version of “Super Size Me,“ living on McDonalds dollar meals and five-dollar pizzas from Little Caesars. But after a week, he said, “I felt like I was going to die.“ Kale was all the rageand cheapso next he tried an all-kale diet.
31、 But that did not work, either. “I was starving,“ he said.C. Rhinehart, who is twenty-five, studied electrical engineering at Georgia Tech, and he began to consider food as an engineering problem. “You need amino acids (氨基酸) and lipids, not milk itself,“ he said. “You need carbohydrates (碳水化合物), not
32、 bread.“ Fruits and vegetables provide essential vitamins and minerals, but theyre “mostly water.“ He began to think that food was an inefficient way of getting what he needed to survive. “It just seemed like a system thats too complex and too expensive and too fragile,“ he told me.D. What if he wen
33、t straight to the raw chemical components? He took a break from experimenting with software and studied textbooks on nutritional biochemistry and the Web sites of the F.D.A., the U.S.D.A., and the Institute of Medicine. Eventually, Rhinehart compiled a list of thirty-five nutrients required for surv
34、ival. Then, instead of heading to the grocery store, he ordered them off the Internetmostly in powder or pill formand poured everything into a blender, with some water. The result, a slurry of chemicals, looked like gooey lemonade. Then, he told me, “I started living on it.“E. Rhinehart called his p
35、otion Soylent, which, for most people, evokes the 1973 science-fiction film “Soylent Green,“ starring Charlton Heston. The movie is set in a dystopian future where, because of overpopulation and pollution, people live on mysterious wafers called Soylent Green. The film ends with the ghastly revelati
36、on that Soylent Green is made from human flesh.F. Rhineharts roommates were skeptical. One told me, “It seemed pretty weird.“ They kept shopping at Costco. After a month, Rhinehart published the results of his experiment in a blog post, titled “How I Stopped Eating Food.“ The post has a “Eureka!“ to
37、ne. The chemical potion, Rhinehart reported, was “delicious! I felt like Id just had the best breakfast of my life.“ Drinking Soylent was saving him time and money: his food costs had dropped from four hundred and seventy dollars a month to fifty. And physically, he wrote, “I feel like the six milli
38、on dollar man. My physique has noticeably improved, my skin is clearer, my teeth whiter, my hair thicker and my dandruff gone.“ He concluded, “I havent eaten a bite of food in thirty days, and its changed my life.“ In a few weeks, his blog post was at the top of Hacker Newsa water cooler for the tec
39、h industry. Reactions were polarized. “RIP Rob,“ a comment on Rhineharts blog read. But other people asked for his formula, which, in the spirit of the “open source“ movement, he posted online.G. One of Silicon Valleys cultural exports in the past ten years has been the concept of “life hacking“: de
40、vising tricks to streamline the obligations of daily life, thereby freeing yourself up for whatever youd rather be doing. Rhineharts “future food“ seemed a clever work-around. Lifehackers everywhere began to test it out, and then to make their own versions. Soon commenters on Reddit were sparring ab
41、out the appropriate dose of calcium-magnesium powder. After three months, Rhinehart said, he realized that his mixture had the makings of a company: “It provided more value to my life than any app.“ He and his roommates put aside their software ideas, and got into the synthetic-food business.H. To a
42、ttract funding, Rhinehart and his roommates turned to the Internet: they set up a crowd-funding campaign in which people could receive a weeks supply of manufactured Soylent for sixty-five dollars. They started with a fund-raising goal of a hundred thousand dollars, which they hoped to raise in a mo
43、nth. But when they opened up to donations, Rhinehart says, “we got that in two hours.“ Last week, the first thirty thousand units of commercially made Soylent were shipped out to customers across America. In addition to the crowd-funding money, its production was financed by Silicon Valley venture c
44、apitalists, including Y Combinator and the blue-chip investment firm Andreessen Horowitz, which contributed a million dollars.I. Soylent has been heralded by the press as “the end of food,“ which is a somewhat bleak prospect. It conjures up visions of a world devoid of pizza parlors and taco standso
45、ur kitchens stocked with beige powder instead of banana bread, our spaghetti nights and ice-cream socials replaced by evenings sipping sludge.J. But, Rhinehart says, thats not exactly his vision. “Most of peoples meals are forgotten,“ he told me. He imagines that, in the future, “well see a separati
46、on between our meals for utility and function, and our meals for experience and socialization.“ Soylent isnt coming for our Sunday potlucks. Its coming for our frozen quesadillas.（分数：71.00）(1).What will be the consequence of his direct study of raw chemical components?（分数：7.10）填空项 1:_(2).What we rea
