For the study, researchers had people read for four hours in the evenings using either an iPad or a 1 printed book. Then at 10 p.m., it was lights out. The researchers 2 the participants’ levels of melatonin, a hormone that helps 3 the sleep cycle, as well as the amount of sleep they got and how alert they were the next morning. What they 4 was that people who read on the electronic tablets took 10 minutes longer to fall asleep and had 5 less REM [rapid eye movement] deep sleep during the 6 of the night, as compared to people who read on paper. In the morning, the e-reading group also found it harder to wake up and feel fully alert—even when they’d had a full 8 hours of sleep. Doctors say adults need 7 to 9 hours of sleep to 7 at their best, but about a third of Americans regularly get by on less. Sleep deprivation can take a serious toll on health; among other things, it’s been linked to an increase risk of heart disease, diabetes and mood problems. Not only that, lack of sleep is also 8 with weight gain. One recent study found children who don’t get enough sleep are almost twice as 9 to be obese by their teenage years. The study was 10 Monday in the Proceedings of the National Academy of Science.

But the research from the OECD (Organization for Economic Co-operation and Development) reveals a wide cultural gap—with a much more positive perception of teacher status in Asia than in Europe. Teachers in England were above average in feeling valued, at 35%, unlike France where the figure was only 5%. The OECD’s Michael Davidson described these as "shocking statistics". B. The OECD, responsible for Pisa tests comparing international education standards, has turned its attention to the state of teaching, examining the working lives of 100,000 teachers and heads in 34 education systems. The economic think-tank argues that the quality of teaching, more than any other factor, determines the outcomes of an education system. C. But the report—Teaching and Learning International Survey (Talis)—shows that many teachers do not feel that the importance of their role is recognised. Only 31% believed that their work was valued by the rest of society. The report says that has implications for attracting young teachers into the profession. D. Within this average were some very wide differences. In Malaysia, South Korea, Singapore and Abu Dhabi there was a strong sense of teaching being highly respected. In Europe, Finland was the only country where a majority of teachers were confident in the status of their job. The Netherlands and England were the next best valued in Europe. But there was a much gloomier outlook for teachers in France, Spain and Sweden, where more than nine out of 10 teachers felt their profession was not respected. Despite this sense of being unappreciated, there were still high levels of job satisfaction—with a large majority saying they would choose teaching again as a career choice. E. The study provides an overview of the different working weeks. It shows that teachers in England are working 46 hours per week in term time, considerably above the international average of 38 hours, with only Singapore, 48 hours, and Japan, 54 hours, working longer. In contrast, teachers in Italy are only working 29 hours per week, with Finland’s teachers working 32 hours. South Korea’s teachers, with some of the best test results in the world, work 37 hours per week. The research includes a comparison of how much time is wasted in lessons because of bad behaviour. Poland has the best behaved pupils, according to this measure, losing 8% of lesson to poor behaviour, with Brazil’s pupils the most disruptive, losing 20%. England has less of a problem with discipline than most other countries, with teachers spending 11% of lesson time on poor behaviour. F. But a more detailed analysis inEngland’s schools shows that higher achieving state schools, rated as outstanding, have less disruption and more teaching time than weaker schools. And independent schools faced less disruption than state schools. In terms of more aggressive behaviour, in Brazil, Mexico, Australia and Sweden, there are reports of regular intimidation and verbal abuse towards teachers. G. The study examines how teachers are deployed—and whether the most experienced staff are where the need is greatest. The research reveals wide differences. In South Korea, the Netherlands and Chile, all high performing education systems in their regions, the most experienced teachers are more likely to be working in schools with the most disadvantaged pupils. In England, the trend is in the opposite direction, with the most experienced staff less likely to be in these more challenging schools. H. The study also provides a profile of the teaching profession. Most are women, with the average age 43 years old. Apart from Singapore, England has the youngest teaching force of any of the education systems in the survey. It has fewer head teachers over the age of 60 than any other developed country. I. The research found that many teachers were working in isolation—a majority did not use "team teaching" with another colleague and only a third observed other teachers’ lessons. Almost half did not receive any feedback from senior staff. The report says that job satisfaction is improved by a greater sense of participation and collaborative working. "We need to attract the best and brightest to join the profession," said Andreas Schleicher, the OECD’s education director. J. A spokeswoman for England’s Department for Education said: "There has never been a better time to be a teacher—and there have never been more teachers in England’s classrooms, with a rise of 9,000 in the last year. "We are incredibly fortunate to have many thousands of dedicated, hard-working teachers, committed to teaching excellence. Teaching is now one of the most attractive career paths for graduates, with a record number of top graduates now joining the profession." K. Labour’s shadow education secretary Tristram Hunt said: "This report is more evidence that raising teacher quality improves children’s learning." He called for all teachers to be qualified and "undertake continued professional development throughout their careers". InEngland, the most disadvantaged students may not receive education from the most experienced teachers.
A storm surge is a mound of water produced when a hurricane moves across a large body of water. Driving wind "pushes" the water so quickly that it "piles up" on the water in front of it, producing a mound of water that is higher than normal sea level. As the storm approaches land, the storm surge can be pushed up the beach and deep into inland areas. It arrives as a rush of water and can be capped by large, strong, pounding waves. Storm surge flooding is often the most deadly and damaging impact of a hurricane. Storm surges are capable of causing total inundation(淹没) of entire coastal areas. A powerful hurricane can produce a storm surge of 15 feet or more. Storm surges of 20, 30 and 40 feet have been experienced in extreme storms. Portions of many important coastal cities and resort areas have thousands of people living on land that is less than 10 feet above sea level. Storm surges can knock down buildings, move trains off of their tracks, carry ships and docks inland, fill subways and do many other types of damage. People who live in vulnerable areas should heed evacuation orders. If they wait for the water to arrive, escape can be impossible. This is because the surge arrives suddenly, and quickly covers a very broad area. Less than two feet of water can drown out a car. Walking through moving water is very difficult. The water can be very cold and the wind chill will cut right through wet clothing! People who cannot escape quickly to higher ground or second stories can easily die of hypothermia in under an hour. Forecasting a storm surge and its characteristics is difficult because there are so many variables. It is difficult to predict the time of arrival, and that makes it impossible to know if high tide or low tide will be contributing to the height of the surge or detracting from it. It is also difficult to know the windspeed at the time of landfall, how much water will be contributed by rainfall, the exact location of landfall and how topography(地形) will influence the movement of water. If you live in an area where an evacuation is ordered, obey that order and leave promptly. What is the difficulty in predicting a storm surge
A. Its arrival time and the tide height.
B. The windspeed and rainfall when it arrives.
C. The place and topography.
D. Multiple factors that are liable to change.
