Careers for Women
It is only seventy years since British women got the right to vote.Some people think this is the main reason why women are so under-represented in politics,trade unions and big businesses.Others feel it is simply because that they are much too busy doing other things.The old saying"a woman's place is in the home"may seem out of date to most people,but the old,fixed image of a woman as a supporting wife and caring mother is certainly still usual一one only has to watch a few television ads.
In 1975 the law did not allow women to be paid less than men doing the same work.Certainly it is usually the case nowadays that women doing the same jobs as men get the same money for doing it. But generally women do not do the same jobs:they do different ones that offer lower salaries.
In the United States,there are two million women entering the workforce every year. The new workers include all ages and backgrounds:teenagers,college students,young housewives,and older women who have lost their husbands.Altogether,more than half of the eighty-four million women in
the United States are now employed or seeking employment.Most of them are still holding tightly to the womanly jobs such as nursing,teaching,catering and office work jobs that can be seen as an extension of the mothering role.
Although the areas women work in are almost all those of"service",a growing number of pioneers are venturing into other fields. They run business;they manage farms;they become astronauts, carpenters,lawyers,truck or taxi-drivers,coal miners,or politicians.They join the army or the navy.So far no woman has become president of the country;but that might happen,as indeed it has happened in other countries.
Apart from looking after people during the day at work,women often have to take care of a family at home too,which may mean they have less energy to compete in the race for professional development. In almost every field,top positions are more likely to be filled by men. While most teachers are women,for example,most head masters are not.School cooks are women,head cooks are men and even cleaners tend to be watched over and directed by male caretakers.
Decades ago women were too busy to get involved in social affairs.
A.Right
B.Wrong
C.Not mentioned

Natural Medicines{{/B}}
Since earliest days, humans have used some kinds of medicines. We know

big hospitals with strange and wonderful equipment. Many parts
of the world still do not have university-educated doctors. Nor do they have
expensive hospitals. Yet injuries are treated. And diseases are often cured.
How By ancient methods. By medicines that might seem mysterious, even

however. Through A. may never be exhausted B. may be dropping rapidly C. is surprisingly big D. is as rich as ever
