Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for-its stadium and theatres, its shops and restaurants. The tourists do not, however, see Pompeii’s people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2000 years.

Once, Pompeii was a busy city of 22,000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano. Mount Vesuvius had not erupted for centuries, so the people of Pompeii felt safe, But they were not.

In August of AD 79 , Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii . When the eruption ended , Pompeii was hurried under 20 feet of stones and ashes. Almost all of its people were dead.

For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861,an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD79 , There  were streets and fountains, houses and shops, There was a stadium with 20,000 seats , Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue color in the bottom, so we know that the people of Pompeii liked wine, They liked bread, too; metal bread pans were in the bakery .In one bakery there were 81 round , flat loaves of bread –a type of bread that is still sold in Italy today . Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye-makeup.

习 * * * * 指出：“科技是国家强盛之基，创新是民族进步之魂。”阅读材料，回答问题。

材料一：表一：我国研究与试验发展（R&D）经费支出

注：R&D经费支出占GDP比重是目前国际通用的衡量科技活动规模、科技投入水平和科技创新能力高低的重要指标。目前，西方发达国家该指标平均水平为3%左右。

材料二：因为利用了最新的科技成果，专车方便、快捷、支付简单。加上企业推广的补贴，优惠的价格吸引不少市民选择专车服务。目前，出租车行业主要依赖政府限制运营数量，实施保护价格的措施来进行运营和管理。专车服务与出租车行业产生了强烈的利益冲突，因此在许多国家的扩张都受到了激烈反对。政府出于经济稳定和就业保障的目的，保护出租车行业的做法受到社会质疑，这种做法会损害消费者权益，容易滋生腐败现象。

材料三：由于专车“跑得太快”，法规“跟不上”，结果就出现了一个灰色地带，使政府对交通客运行业的管理变得困难。但专车服务的新模式，又能满足市场上高品质、多样化和差异化的出行需求。对此现状，中国交通运输部认为，不能对专车“一棍子打死”，要按照以人为本、鼓励创新、趋利避害、规范管理的原则进行管理。

根据材料和所学《政治生活》知识，谈谈我国政府怎样才能在科技进步和社会和谐中达成平衡。
