材料一：农业谚语和诗歌反映了中国劳动人民对生产经验的总结：

谚语一：立夏到小满，种啥也不晚……清明请，六畜兴；清明雨，百果损。

谚语二：三分种来七分管，十分收成才保险。

诗歌：昼出耘田夜绩麻，村庄儿女各当家。

材料二：从烟台入口的洋布除少部分在本埠附近及山东东部、南部消费外，大部分进入山东北部、西部地区……。1875年，烟台海关税务司就此谈到：“棉布货物由运输商人们运到这里，……有八分之六的棉布运往内地，八分之二的棉布可能留下来就地出售……。”在90年代，济南府的商人每年购进大约200万海关两的洋布，这几乎全部包揽了烟台进口的洋布。

    Can you imagine a pair of shoes that could tie themselves? All you would have to do is to put them on and push a button. Well, this idea is becoming a real reality. The shoe company Nike created the self-tying shoe! This idea first came from the movie Back to the Future II, Nike has been working for years to create a shoe that can do this in real life. They have finally done it with Nike HyperAdapt 1.0.

    So how do they work? According to Nike, the shoe is “powered by an underfoot-lacing mechanism (脚下系带装置)”. This is kind of like a small motor (发动机) that has the power to lace the shoes. All the wearer has to do is to put them on, and at first, the shoes are very loose (松的). But then you can push the “+” button (按钮), and the shoes will tighten to be the perfect fit for the wearer. To take them off, all you have to do is to push the “－” button, and the shoes will be easily off.

    They haven't been released to the public yet, and the cost of the shoes is still unknown. But you might be able to get a pair of your own closer to the holiday season this year.
