第10-13题为套题 阅读材料一：历次全国人口普查的数据显示，我国65岁及以上人口在总人口中所占的比例，1953年为4.4%，1964年为3.6%，1982年为4.9%，1990年为5.6%，2000年为7.0%。现在中国的养老问题已经日趋严重，人口老龄化给中国的经济、社会、政治、文化等方面的发展带来了深刻影响，庞大老年群体的养老、医疗、社会服务等方面需求的压力也越来越大。养老保障的负担正日益沉重。 阅读材料二：为缓解人口老龄化的压力，上海市计划生育部门于2009年7月宣布鼓励符合条件者多生一胎，但强调计划生育政策并未改变。 根据世界卫生组织的标准，我国已于哪一年进入老龄化国家？（ ）

A:2000年 B:1990年 C:1982年 D:1964年

表面上看来，美国1982年和1964年的大学毕业生很像：相当保守，穿着入时，对传统有兴趣，并且尊重父母。但二者却存在着一个根本的不同点：1982年的学生有一大半的人在他们上大一接受调查时表示，有好的收入是他们决定上大学的一个重要因素。
上文最有效的支持了以下哪一个结论( )

A:与担心经济的1982年大学毕业生相比，1964年的大学毕业生更加注重学习本身 B:不到半数的1964年毕业生在大一接受调查时表示他们入学的重要原因是将来能挣得更多 C:事实上，1982年的大学毕业生比1964年的大学毕业生更实际 D:与1982年相比，1964年的教育背景并没有构成决定收入的重要因素

One of the oldest seafaring ships in the world has been reconstructed after seven years’ patient archaeological work. The ship, a 60- foot sailing vessel, sank off the coast of Cyprus in the days of Alexander the Great around the year 300 B.C. Its discovery and restoration have now thrown new light on the ancient trade routes and shipbuilding techniques.
What makes the Cyprus ship so informative is the remarkable state of preservation--mainly due to an unusual feature of its design. The hull was sheathed on the outside with lead that was fixed to the timber with bronze tacks which helped the wooden frame survive 2000 years under the sea.
The first clue to the wreck’s existence came in’ 1964 when a sponge diver from the present- day resort of Kyrenia came across a pole of amphorae (ancient storage jugs). Unfortunately his diving air supply ran out just at that moment, so that he had no time to mark the spot. It took him three years and hundreds of dives before he chanced upon them again.
He reported his find to an underwater archaeological team from the University of Pennsylvania which was surveying the Cypriot coasts for wrecks. After checking his description, the team decided to concentrate their resources on the Kyrenia ship, and over the next two years a team of no fewer that 50 archaeologists and divers took part in the excavation.
With the help of a metal detector, the team discovered that wreckage lay scattered over a 2000 - square - foot area, often buried beneath sand and sea - weed. Each item was carefully photographed in its place, and a system of plastic grids stretched over the whole site so that it could be accurately mapped.
More than 400 amphorae lay buried in the sand. The ship had been carrying a cargo of wine and almonds. More than 9000 of these were found in or nearby the amphorae, their outer shells still perfectly preserved. As well as these, there were 29 stone grain mills, being carried both as cargo and as ballast. These were carefully stored in three rows parallel to the axis of the keel.
As well as the main cargo, there were other small finds. Four wooden spoons, four oil jugs, four salt dishes and four drinking cups suggested the number of crew on the ship s last voyage. There was an axe, and near the intricately carved mast lay a wooden pulley, used to raise and lower the yard. A bronze cauldron, used perhaps to prepare the crew’ s meals was also lying in the wreck.
Of five bronze coins found, none dated earlier than 306 B.C. Carbon - 14 analysis of the almond cargo pinpointed their date at about 288 B. C. , but that of the ship’ s planking suggested an earlier of 370 B. C. Thus the Kyrenia ship was more than 80 years old the day she sank-a long life for a wooden hull and proof of the good craftsmanship of her builder.

A:In 1969. B:In 1964. C:In 1967. D:Seven years after 1964.
