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。

Passage 2

Questions 6 to 10 are based on the following passage:

When aluminum was first produced about a hundred and fifty years ago, it was so difficult to separate form the ores in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricity approximately three quarters of a century later. The new method was so much cheaper that aluminum because practical for many purposes, one of which was making pots and pans.

Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientists have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much.

Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engine of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge “airbus” planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them, Aluminum is also being used extensively in the building industry in some countries.

Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite (铝土矿), which is one of its chief sources, is also one of the earth’s most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal.
