In 1990 a report was published about what the earth might be like 20 years from then on. The report was a result of a three-year  36 .
According to the report, the picture of the earth in the year 2010 is not a  37  one. The world will be more  38  because the population will continue to grow . The population could be  39  6 300 million, almost 2 115 million more than in 1985 .More people would move into cities, especially cities in  40  countries . Cities like Cairo and Jakarta probably would  41  have 15 million by then .
Food production will  42  , but not enough to feed all the people . Farmers will grow 90% more food than they did in 1985,  43  most of the increase would be in countries that
 44  produce enough food for their people . Little increase is  45  in South Asia, Africa and the Middle East . Poor farming ways are 46  large areas of crop land, changing farms into deserts . More farmland is  47  as cities become larger and more houses are built . 48  will get worse as industrial countries burn more coal and oil .Many of the world’s  49  could disappear as more and more trees are cut down . Energy will continue to be a serious problem . The experts say their picture of the earth for the year 2010  50  . They only carried out the situation that  51  today . By changing the situation, by  52  the problems, the picture can be changed . There is  53  time for the nations of the world to work  54  a plan of action . But they warned that  55  too long to make decisions would greatly reduce the chances of success .

如图所示,理想变压器原、副线圈的匝数比为10:1,b是原线圈的中心接头,电压表V和电流表A均为理想电表.从某时刻开始在原线圈c、d两端加上交变电压,其瞬时值表达式为u=220sin100πt(V).下列说法正确的是(  )

A.当单刀双掷开关与a连接时,电压表的示数为22V

B.当单刀双掷开关与b连接时,电压表的示数为11V

C.当单刀双掷开关与a连接,滑动变阻器触头P向上移动的过程中,电压表的示数不变,电流表的示数变大

D.单刀掷开关由a扳向b时(滑动变阻器触头P不动),电压表和电流表的示数均变大
