如图所示的电路叫热电偶电路．将铜丝与铁丝的两个接头分别放在温度不同的环境中，例如冰水混合物中和酒精灯的火焰上，此时会发现电流表有读数．课外小组的同学研究了这个电路中电流与温度差的关系，他们得到的数据如下表：

①从数据中，课外小组的同学可以得到这样的结论：两金属接点的温度差越 ____，电流大．

②写出一个这样的热电偶电路可以用在电路中作为 ____使用．它将 ____能转化为 ____能．

       霍丘^①知县阳湖左君，治霍丘既一载，其冬有年。父老数十人，来自下乡，盛米于筐，有稻有稉，豚蹄鸭鸡，伛偻提携，造于县门。君呼之入，曰：“父老良苦，曷为来哉？”顿首曰：“边界之乡，尤扰益偷。自耶之至，吾民无事，得耕种吾田。吾田幸熟，有此新谷，皆耶之赐，以为耶尝。”君曰：“天降吾民丰年，乐与父老食之；且彼家畜，胡以来？”则又顿首曰：“往耶未来，吾民之猪鸡鹅鸭，率用供吏，余者盗又取之。今视吾圈栅，数吾所育，终岁不一失，是耶为吾民畜也，是耶物非民物也。”君笑而受之，劳以酒食。皆欢舞而去，曰：“本以奉耶，反为耶费焉。”士民相与谋曰：“吾耶无所取于民，而禄不足以自给，其谓百姓何？请分乡为四，各以月入米若薪。”众曰：“善。”则请于君，君笑曰：“百姓所以厚我，以我不妄取也，我资米若薪于百姓，后之人必尔乎索之，是我之妄取无穷期也。”不可。亳州之民，有诉于府者曰：“亳旧寡盗，今而多，其来自霍丘。霍丘左耶不容盗，以祸亳，愿左耶兼治之。

    Mr. White's family decided to repair their house. Mr. White bought the house two and a half years ago. Since his kids were growing up, he and his wife wanted to make some changes to the house.

    They decided to knock down their living room wall to open up the space. When the wooden walls were moved, they were shocked to find a lizard (蜥蜴) stuck in the small space between the walls. The lizard's foot was stuck by a nail (钉子) which was knocked into the wall from the other side several months ago. However, they wondered how the lizard had survived so long without moving from that place.

    The family decided to wait for a while and see how the lizard survived several months without moving. While they were doing other things, they kept an eye on the lizard. The son, Ray, suddenly shouted, “Dad, look here!”

    Another lizard appeared, carrying food to the stuck lizard's mouth. That was a real surprise! Everyone was touched that the lizard fed the other one for all this time.

    Both lizards had never-ending hope for each other and carried their hearts with love and care. Why can't we humans always carry that kind of love in our hearts? Life is full of all kinds of difficulties. What we can do is to give our hand to the one in need and share our love. Sharing is caring.
