材料一：2017年1月，我国进出口总值2．18万亿元人民币，比去年同期增长19．6%，以超出本场预期的增速迎来2017年“开门红”。对于1月外贸增速的“超预期”，专家表示，一个直接原因就是价格的上涨，1月份铁矿砂、原油、煤等大宗商品价格分别上涨81．3%、46．7%、110%。国际大宗商品价格上涨的背后，是因为国际市场的活力正在逐步恢复，全球经济呈现出比较明显的回升态势。另外，去年以来人民币总体上呈贬值态势，客观上也对出口产生了推动作用。从内部因素看，国家稳出口、促增长等一系列政策举措的实施，为我国外贸回稳向好发展创造了良好的政策环境。

对于外贸增速的“超预期”，专家表示，单月数据的波动，并不能代表我国外贸的整体状况。当前，原材料产品价格提升较快的态势可能会对国内产品成本形成一定压力，对今后的出口带来不利影响；与此同时影响我国外贸发展的不确定因素仍然很多，支撑外贸持续向好的基础尚不牢固。中国外贸的转型升级还必须在产品结构上下功夫，资源类产品出口比重要下降，劳动密集型产品也要有所下降，真正把技术密集型产品的出口比重增上来，我们仍须攻坚克难、加倍努力。

材料二：2017年1月18日，******在日内瓦万国宫出席“共商共筑人类命运共同体”高级别会议，并发表题为《共同构建人类命运共同体》的主旨演讲。***指出，人类正处在大发展、大变革、大调整时期，也正处在一个挑战层出不穷、风险日益增多的时代。回收过去100多年的历史，全人类的共约愿望，就是和平与发展。让和平的薪火代代相传，让发展的动力源源不断，让文明的光芒熠熠生辉，是各国人民的期待，也是我们这一代政治家应有的担当。中国方案是：“构建人类命运共同体，实现共赢共享。”主张共同推进构建人类命运共共同体伟大进程，坚持对话协商、共建共享、合作共赢、交流互鉴、绿色低碳，建设一个持久和平、普遍安全、共同繁荣、开放包容、清洁美丽的世界。

    His palms were sweating. He needed a towel to dry his grasp. The sun was as hot as the 1 he faced today at the National Junior Olympics. The bar (横竿) was set at 17 feet. That was three inches higher than his personal best. Michael Stone faced the most 2 day of his pole-vaulting(撑竿跳高) career.

    You couldn't tell whether Michael Stone was surprised, excited or vain about clearing the bar at 17 feet. As soon as he 3 on the inflated(充了气的) landing mat, Michael immediately began 4 for his next attempt at flight. He seemed 5 the fact that he had just beaten his personal best 6 three inches and that he was one of the first two competitors in the pole-vaulting 7 at the National Junior Olympics.

    When Michael 8 the bar at 17 feet 2 inches and 17 feet 4 inches, again he showed no 9. As he lay on his back and 10 the crowd sigh, he knew the other vaulter had missed his final jump. He knew it was time for his final jump. Since the other vaulter had 11 misses, Michael needed to clear this vault to win. A 12 would get him second place. It was nothing to be ashamed of,13 Michael would not 14 himself to have the thought of not winning first place.

    He rolled over and found his pole, stood and stepped on the runway that 15 the most challenging event of his 17-year-old life.

    As he sprinted (冲刺) down the runway, something felt wonderfully different, yet familiar. When he took a deep breath, it happened. He began to 16 like an eagle.

    He later went on that day to clear 17 feet 6 inches: a new National and International Junior Olympics record.

    With all the media attention and sponsorship possibilities, Michael's life would never be 17 again. It wasn't just because he won the National Junior Olympics and18 a new world record. And it wasn't because he had just increased his personal best by 9 inches. It was simply because Michael Stone is blind.

    A chance encounter can sometimes make all the 19 to whether hardship brings 20 the best in us or the worst.
