When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against

33、to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts
34、 for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms chewing alone was not responsible for the polyethylene breakdown, the researchers made so
35、me worms into paste (糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass apparently broken down by enzymes (酶) from the worms stomachs. Their findings were published in Current Biology in 2017.Federica Bertocchini, co-author of the study, says the worms ability
36、to break down their everyday food beeswax also allows them to break down plastic. “Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well,” she explains. “The wax worm evolved a method or system to break this bond.”Jennifer DeBruyn, a microbiologist at
37、 the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the bre
38、akdown. Is it an enzyme produced by the worm itself or by its gut microbes (肠道微生物)?Bertocchini agrees and hopes her teams findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process not simply “millions of w
39、orms thrown on top of the plastic.”43. What can we learn about the worms in the study? A. They take plastics as their everyday food. B. They are newly evolved creatures.C. They can consume plastics. D. They wind up in landfills.44. According to Jennifer DeBruyn, the next step of the study is to . A.
40、 identify other means of the breakdown B. find out the source of the enzymeC. confirm the research findings D. increase the breakdown speed45. It can be inferred from the last paragraph that the chemical might . A. help to raise worms B. help make plastic bagsC. be used to clean the oceans D. be pro
41、duced in factories in future46. What is the main purpose of the passage? A. To explain a study method on worms. B. To introduce the diet of a special worm.C. To present a way to break down plastics. D. To propose new means to keep eco-balance.DPreparing Cities for Robot CarsThe possibility of self-d
42、riving robot cars has often seemed like a futurists dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also clea
43、red the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isnt leading the way here. Companies have been testing their vehicles in cities across the country. Its hard to predict when driverless cars will be
44、 everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.While much of the debate so far has been focused on the safety of driverless cars (and
45、rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly an
46、d more shared.Do we want to copy or even worsen the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride,
47、which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer p
48、eople to take public transport an unwelcome side effect researchers have already found in ride-hailing (叫车) services.A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissi
