[单选题]It is everywhere,as visible as it is vilified.From car parts to crisp packets,plastic has suffuse the Earth,and beyond-in 1969 Neil Armstrong planted a nylon Stars and Stripes on the moon.More than 8bn tonnes has been produced since the 1950s,enough to wrap the continents in cling film four times over.1 Untold tonnes end up as irretrievable ocean flotsam,which sunlight and salt fragment into microscopic pieces that attract toxins and may be gulped by creatures that become seafood Plastic weighs heavily on the mind,too.2 In Britain hatred of plastic unites the right-wing Daily Mail,the leftie Guardian,and the queen,who has banned plastic straws from her castles.But hold on.The little scientists know about plastic suggests that although it is the most noticeable pollutant it is far from the most harmful.Using less is at best a partial solution.a bet-ter answer is to collect more-especially in Asia The effects of plastic on nature and human health are hard to gauge.Most polymers are chemically inert.That makes them durable.3 It also makes them less likely to be a health risk to humans and beasts.As a pollutant,their impact is much lower than less tangible menaces.By one estimate,the environmental and social costs of plastic run to 9 139bn a year,chiefly from the greenhouse gases produced in its production and transport.The figure for farming is$3trn.Fertiliser run-off alone causes S 200bn-800bn worth of damage to the ocean,compared with S 13bn from plastic marine litter.Then look at the alternatives.A cotton tote bag must be used 131 times before its carbon footprint improves on that of a throwaway carrier bag This does not stop plastic from being a problem.4 Prohibition makes sense in poor places like Bangladesh and Kenya that lack proper waste-management systems.It is less useful in tidy France where rubbish collection works smoothly.It would be more effective for rich countries to shore up their recycling industries.They may have little choice in any case A carbon tax may spur recycling,which is less energy-intensive than producing virgin plastic Mandating minimum recycled content in plastic containers,as California has since 1991,is also a useful tool.Governments could exempt second-hand polymers from value-added tax;after all,the tax has already been paid on the fresh source material 5.Among the ten biggest plastic polluters,all but two are in developing Asia.Together,they account for two-thirds of the plastic spewed into the ocean.Of these,only China could afford Western-style waste-management in the near future.Others are just waking up to the problem;before plastic began piling up,it reasonably seemed less of a priority for governments.Bangladesh may be able to copy India which,despite its 1.3bn people,falls outside the top ten thanks to armies of ragpickers.The rest,like Vietnam or Thailand,may be too wealthy for raddiwallahs,yet too poor for sophisticated rubbish collection.The rich world should focus its attention-and resources,including charity-on chivvying them along.That is the surest way to stem the plastic tide

[单项选择]In the thirteenth century, in order to discover what language a child would speak if he heard no mother tongue, Frederic II told the nurses to keep silent, all the infants died before the first year. But clearly there was more than language deprivation here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is serious affected.
Today no such ruthless deprivation exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the cues and signals of the infant, whose brain is programmed to mop up language rapidly. There are critical times, it seems, when children learn more readily. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once
A. Frederick’s experiment proved that children are born with the ability to speak.
B. Good mothering is important only after the child has learned to speak.
C. The author does not believe that children select and analyze their language.
D. If the mother does not respond to her child’s signals, the child will make little effort to speak.
