如今,中国正步入老龄化社会,因此独生子女一代面临着巨大的工作和生活压力。中国政府开始适当调整计划生育政策,允许一些家庭在特殊情况下生育二胎。但调查显示,很多夫妻迫于不断加重的经济压力,放弃生育二胎。因此,要从根本上解决老龄化的问题不能依靠出生率的上升,最有效的办法是建立有效的社会保障制度。
Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles. But by the middle of this century, men’s and women’s roles were becoming less firmly fixed.
In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam.
In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on “overtime” work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods.
In the 1970s, the feminist movement, or women’s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women’s jobs as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion.
Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations.

If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.
The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.
From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.
The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.
In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.
The airlines’ optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.
1.British airlines confide in the fact that__.
A.they are more powerful than other European airlines.
B.their total loss won’t go beyond a drop of 5% passengers.
C.their traffic levels will return in 2-3 years.
D.traveling by rail can never catch up with traveling by air.
2.The author’s attitude towards the drop of passengers may be described as__.
A.worried.B.delightedC.puzzled.D.unrivaled.
3.In the passage, British Rail (Para 6) is mentioned to__.
A.provide a comparison with Eurostar.
B.support the airlines’ optimism.
C.prove the inevitable drop of air passengers.
D.call for electrification and modernization of the railway.
4.The railway’s Brussels route is brought forth to show that__.
A.the Eurostar train service is not doing good business.
B.the airlines can well compete with the railway.
C.the Eurostar train service only caused little damage.
D.only some airlines, such as Air France, are suffering.
5.The passage is taken from the first of an essay, from which we may well predict that in the following part the author is going to__.
A.praise the airlines’ clear-mindedness.
B.warn the airlines of high-speed rail services.
C.propose a reduction of London/Paris flights.
