积温是一个地区一年内日平均气温≥10℃，持续期内日平均气温的总和。读我国局部地区积温分布图（图），回答下题。

民主政治是人类迈向现代化的重要表现，民主思想的发展与自然科学的进步息息相关。阅读材料，回答下列问题。

材料一  天子受命于天，天下受命于天子，一国则受命于君。君命顺，则民有顺命；君命逆，

则民有逆命。受命之君，天意之所予也。故号为天子者，宣视天为父，事天以孝道。

                                                ——董仲舒《春秋繁露》

材料二  没有权柄不是出自神的......君主的权力是上帝通过教皇赐予的......治理人民的国

王是上帝的一个仆人。                             ——（意大利）阿奎那

材料三   牛顿已经发现了一个数学上能证实的根本的宇宙规律......实际上，自然界好像一个巨大的机械设置，按照通过观察、实验、测量计算可以予以确定的某些自然法则进行运转，人类的各门知识都可以分解为有理性的人所能发现的少数简单的、始终如一的定律。人们开始把牛顿的物理学分析方法应用于整个思想和知识领域，不仅应用于物理学领域，而且应用于人类社会。                      

              ——(美)斯塔夫里阿诺斯《全球通史》

材料四  牛顿确立的新规范不仅是近代科学革命的顶点，而且也是人类思想史上最深刻的革命，它的影响远远超出了物理学范围。

材料五  人人享有自由平等的权利而不论其出身。人们应自由订立社会契约，组成国家。社会中应有“共同意志”，人人遵守。社会契约就是共同意志的体现，代表所有人的权利与自由。这是至高无上的人民主权，不可侵犯，不得转让，不受限制，不准分割。为维护这一主权，必须使人人在法律面前一律平等，包括立法、司法、守法、受法律保护和受法律制裁各方面的平等。政府官员只是人民委派的工作人员，不享有主权。随着政府职位诱惑力的加大，人民应采取更有力的监督手段。人们在行使自由权时，绝不允许损害他人的自由，否则他自身也就不自由了。这时，共同意志就要通过法律手段制裁他，“强迫他自由”     

                                             ——卢梭《国家契约论》

      The freezing Northeast hasn't been a terribly fun place to spend time this winter, so when the chance came for a weekend to Sarasota. Florida. my bags were packed before you could say “sunshine. I left for the land of warmth and vitamin C(维生素C), thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness.Swimming pools, wine tasting, and pink sunsets(at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part—particularly to my taste, dulled by months of cold­weather root vegetables—was a 7 a．m. adventure to the Sarasota farmers'market that proved to be more than worth the early wake­up call.

      The market, which was founded in 1979, sets up its tents every Saturday from 7 a．m. to 1 p．m., rain or shine, along North Lemon and State streets.Baskets of perfect red strawberries; the red­painted sides of the Java Dawg coffee truck; and most of all, the tomatoes:

amazing，large，soft and round red tomatoes.

      Disappointed by many a broken, vine­ripened(蔓上成熟的) promise, I've refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they're unfailingly dry, hard, and tasteless.But I homed in, with uncertainty, on one particular table at the Brown's Grove Farm's stand，full of fresh and soft tomatoes the size of my fist.These were the real deal—and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn't be experiencing again for months.

       Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown's Grove Farm is one of the suppliers for Jack Dusty, a newly opened restaurant at the Sarasota Ritz Carlton, where—luckily for me—I was planning to have dinner that very night.Without even seeing the menu, I knew I'd be ordering every tomato on it.
