【科技创新  喜事多】

材料一：如图

【备注】①研发经费的多少是考察一国科技水平与能力的重要指标，2015年我国研发投入总额实现新的突破。②2015年中等发达国家研发经费投入强度（研发经费与GDP之比）为2.07．2014年美国、德国、日本的研发投入强度分别为2.74、2.84和3.59。

材料二：2016年11月是我国科技成果的收获月：1日，我国自主研制的新一代隐身战斗机歼一20在第十一届珠海航展开幕式上首次公开亮相；3日我国最大推力新一代运载火箭长征五号，在中国文昌航天发射场点火升空；4日使用中国自主芯片制造的世界上首台运行速度超过十亿次的超级计算机“神威•太湖之光”问鼎全球超算排行榜的最高席位；17日中科院软件研究所获得国际高胜能计算应用领域最高奖﹣戈登贝尔奖；18日神舟十一号飞船返回舱在内蒙古中部预定区域成功着陆。

    In the Charles E. Johnson Elementary School in New York, there is a special radio. It gives people warnings (警报) about bad weather.

    One day, there came a sound from the radio. This sound brought the piece of news: a heavy storm was coming. William Tomic, principal (校长) of the school, he asked teachers to bring children indoors and put them in a safe place at once.

    Minutes later, the storm came. However, because of the warning of the radio and the quick work of the principal, no one was hurt. “The radio really did work very well. 我们对它的工作感到很高兴,” William Tomic said. “The parents were as well.” The US government hopes there will be more such success stories. It plans to give this kind of radios to all 97, 000 public schools in the country.

    Every year, more than 10,000 big thunderstorms, 2,500 floods, 1,000 tomatoes (龙卷风) and some hurricanes (飓风) take place in the US, so the warning radios are very useful.

    They not only give people warnings about bad weather, but also give warnings about other dangerous things.
