188. Is it difficult for you to get up in the morning? Do you sometimes oversleep? Are you often late for work or school? Yes? Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed will get you up in the morning! Here is how it works: The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music or other pleasant sounds. A few minutes later, a second recording plays. The second recording can be loud music or unpleasant sounds. If you don’t get up after the second recording, you’ll be sorry. A mechanical “foot” is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few more minutes. What! You’re still in bed! Slowly, the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical. You slide off the bed and onto the floor. You are awake and out of bed. Hiroyuki made his bed because he wanted to win a contest. He works for Honda Motor Company. Once every two years, Honda has a contest—the “All Honda Idea Contest”. In 1996 Hiroyuki won a prize for his bed.

What is NOT a problem when carrying coal ________．A.The requirement for through-ventilationB.The corrosion some types of coal will cause to the shipC.Spontaneous heatingD.Generation of methane gas
Which statement is correct concerning the carriage of coal in bulk ________．A.Coal should be vented with surface ventilation onlyB.Because of its inherent vice，coal should not be loaded wetC.Dunnage should be placed against ship's sides and around stanchionsD.Through ventilation，as well as surface ventilation，should be provided whenever possible
A growing number of countries want to phase out coal entirely, a transition eased by cheap natural gas and cost of wind and solar power. That is good news. Coal has been the largest engine of change to date, accounting for nearly a third of the rise in average temperatures since the Industrial Revolution. Any pressure on it therefore counts as progress.Asia accounts for 75% of the world's coal demand. The Chinese goverment has taken steps to limit pollution and support renewables. Yet coal consumption there rose in 2018, as it did the year before. In India coal demand grew by 9% last year. In Vietnam it swelld by altmost a quarter.To keep the rise in global temperatures to no more than 1.59C relative to pre-industrial times, climatologists insist that almost all coal plants must shut by 2050, which mcans starting to act now.Today's trends would keep the last coal plant open until 2079, cstimates UBS, a bank. Asia's coal-fired power regiment has a sprightly avcrage age of 15, compared with a creaky 40 years in America, close to retirement.There are several reasons for this, but one stand out govemment I support. In India state-owned companies invest more than $6bn in coal mining and coal-fired power each year,statebacked banks provide some $10.6bn in financing. Indoncsia doles out more than S2bn annually for consumption of coalfired power. Japan and South Korca finance coal projccts outside their borders.Govermment support is hardly surprising. State-backed coal firms make money and create jobs. W ind turbines and solar panels provide power only intermittently; for now, dirtier power plants are needed as back up. Gas is pumelling coal in America, but remains a bit-player in India and much of South-East Asia, since it has to be imported and is relatively expensive.Neverheless, govermments betting on coal face three big risks. One is environmental.Emissions from coal plants that are already built- -let alone new ones- will ensure that the world exceeds the level of carbon-dioside emissions likely to push global temperatures up by more tham 1.5%C.There is an cconomio risk, too. Public-sector zeal for coal is matched only by private-sector distaste. Banks, including Asian ones, have increasingly said they will stop funding new coal plants. Wind and solar farms make coal look increasingly expensive. A study has found that private banks provided thre-quarters of loans to Indian renewables projects last year, state-backed banks doled out two-thirds of those for coal.And then there is politics. Voters do not like breathing soot. More of them are concemed about elimnate change, too, as they face unpredictable growing seasons, foods and droughts. Which of the followving statements is true?( ).。A. Govemment support is an important factor for rising coal demand in AsiaB. Japanese govermment does not support coalC. Solar power is the most used energy in rich countriesD. Gas is playing a bigger role in most Asian countries
