材料一  罗斯福在1933年的就职演说中把“免于匮乏的自由”和“免于恐惧的自由”与“言论自由”“信仰自由”并列为“四大自由”，这是资本主义政治理念的重大发展。

——陈启懋《罗斯福“新政”是现代资本主义的开端》

材料二1945年4月，罗斯福总统逝世，重庆各界举行各种悼念活动。***机关报《新华日报》也发表了题为《民主巨星的陨落——悼罗斯福总统之丧》的社论，指出“他(罗斯福)用大无畏的精神推行新政……度过了危机，安定了国民生活”。

材料三  新中国成立后，罗斯福新政从中学历史教科书中消失……1982年，罗斯福新政首次作为一个约定俗成的历史概念被写入高中历史教科书。此后，罗斯福新政成为中学历史教科书重要的学习主题之一。

——据杨梅《“时空”坐标中的罗斯福新政》

    Most American families like to have a vacation in summer. Summer is a good season for vacation. It is often hot in July and August.

    Children do not go to school in those two months. Some people like to stay at home, read books, or watch TV. Many families take their lunch to eat at a place with many trees or a nice lake. Some people have enough time and money to travel to other countries like France, Japan and Australia. They usually fly to these countries. Many families travel by car or train to see interesting places in their own countries. Their favorite city is New York.

    Not everyone likes to go to busy cities. Some families travel to mountains or beautiful valleys（山谷）.
