习题精选系列答案Britain is set to face an increase in cold winters, with up to one-in-seven hitting the UK with longer periods of time when temperatures are below freezing, a study has suggested．The prediction was based on research that found out how low solar activi
ty affected winter weather patterns．
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age"．The findings appear in the journal Environmental Research Letters．"We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading．
Using the Central England Temperature （CET） record, the world's longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures．"The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3．50℃ and 2．53℃ respectively," they wrote．
"However, the mean value for the previous 20 winters had been 5．04℃．The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future．"
Last year．Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditio
ns that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region．Professor Lockwood, while acknowledging that there were a range of possible meteorological factors （气象因素） that could influence blocking events, said the latest study moved things forward by showing that there was "impro
vement in the predictive skill" when solar activity was taken into consideration．
【小题1】We can know from the second paragraph that _____．
| A．research shows that Britain will soon fall into an ice age |
| B．Mike Lockwood's research focuses on space environment physics |
| C．it was quite cold in Britain over the entire winter last year |
| D．so far one-in-seven winters have been very cold in Britain |
| A．average | B．stable | C．ungenerous | D．changeable |
| A．It was sunspots that blocked warm westerly winds reaching Europe． |
| B．Meteorological factors hardly have any influence on blocking events． |
| C．The latest study done by Professor Lockwood was of little practical value． |
| D．Considering solar activity or not affects the accuracy of weather forecasting． |
| A．Another big danger approaching the UK |
| B．Research finds out solar activity is to blame for the cold |
| C．UK faces more cold winters due to weaker solar activity |
| D．Changes in weather patterns should be responsible for low solar activity |
The greatest recent changes have been in the lives of women, during the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty five and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances （家用电器）and convenience foods.
This important change in women’s way of life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full time job. However, when they married, they usually left work at once and never returned to it. Today the school leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards, return to full or part-time work. Such changes have led to a new relationship in marriage, with both husband and wife accepting a greater share of the duties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the home, according to the abilities and interest of each them.
