There have been great changes 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 about eight children, of whom about 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(方便) 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.

Electric ears are dirty.In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about "zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---usually coal, oil,but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.
In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greens are. covering their eyes---"If I can't see it, it's not happening." Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat---at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars bum more fuel than gas-powered ones. If our electricity came mostly from nukes; or geothermal,or hydro, or solar, or wind,then an electric car truly would be clean. But for political, technical,and economic reasons,we don't use much of those energy sources.
In addition,electric cars' batteries which are poisonous for a long time will eventually end up in a landfill.And finally, When cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.
