ury, womens progress can be celebrated across a range of fields.They hold the highest political offices from Thailand to Brazil, Costa Rica to Australia. A woman holds thetop spot at the International Monetary Fund; another won the Nobel Prize in economics. Self-madebillionaires in Beijing, tech innovators in Silicon Valley, pioneering justices in Ghana—in these andcountless other areas, women are leaving their mark. But hold the applause. In Saudi Arabia, women arent allowed to drive. In Pakistan,1,000 womendie in honor killings every year. In the developed world, women lag behind men in pay and politicalpower. The poverty rate among women in the U.S. rose to I4.5% last year. To measure the state ofwomens progress. Newsweek ranked 165 countries, looking at five areas thataffect womens lives: treatment under the law, workforce participation, political power, and access toeducation and health care. Analyzing data from the United Nations and the World EconomicForum,among others, and consulting with experts and academics, we measured 28 factors to come up with ourmakings. Countries with the highest scores tend to be clustered in the West, where gender :discrimination isagain.st the law, and equal rightsare constitutionally enshrined (神圣化). But there were some surprises.Some otherwise high-ranking countries had relatively low scores for political representation. Canadaranked third overall but 26th in power, behind countries such as Cuba and Burundi. Does this suggest thata woman in a nations top office translates to better lives for women in general？ Not exactly. "Trying toquantify or measure the impact of women in politics is hard because in very few countries have there beenenough women in politics to make a difference," says Anne-Marie Goetz, peace and security adviser forU.N. Women. Of course, no index can account for everything. Declaring that one country is better than another inthe way that it treats more than half its citizens means relying on broad strokes and generalities. Somethings simply cant be measured. And cross-cultural comparisons cant account for differences of opinion.Certain conclusions are nonetheless clear. For one thing, our index backs up a simple but profoundstatement made by Hillary Clinton at the recent Asia-Pacific Economic Cooperation summit. "When weliberate the economic potential of women, we elevate the economic performance of communities, nations,and the world," she said. "Theres a stimulative effect that kicks in when women have greater access tojobs and the economic lives of our countries: Greater political stability. Fewer military conflicts. Morefood. More educational opportunity for children. By harnessing the economic potential of all women, weboost opportunity for all people. " What does the author think about womens progress so far？

A.It still leaves much to be desired.

B.It has greatly changed womens fate.

C.It is too remarkable to be measured.

D.It is achieved through hard struggle.

Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate take one penny and double every day for one month. After the first week, you would have only 64 cent, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on“all of a sudden” took from he beginning of human 1ife to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行) a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960 only thirty years and in 1975 world population reached 4 billion which is another billion people in only fifteen years.

World population is increasing at a rate of 9, 000per hour, 220,000 per day and 80 million per year.

This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries such as Columbia, Thailand, Morocco, Costa Rica and the Philippines are doubling their population about every twenty-one years with a growth rate of 3.3 percent a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8 percent per year.Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.
