Dear NMAI(National Museum of the American Indian) Supporter，

Old stereotypes(思维定式) die hard. And when it comes to the way Native Americans have been viewed throughout history and continue to be viewed today, the stories about life in Indian Country are sadly overshadowing the truths. Most Native Americans don't live in tipis(圆锥形帐篷), and we don't greet one another by saying,  “How.”

To combat misconceptions like these, I need help from people who understand there's more to Native American cultures than the offensive cartoons that you see in movies and television.

I think that you might be one of these people.

Please join NMAI today and enjoy exclusive benefits like our full－color quarterly magazine American Indian, and Members－only discounts at all Smithsonian, NMAI Museum Stores, and at our Zagat－rated Mitsitam Native Foods Café.

Plus, through this email, you can take advantage of our special price of $22－more than 10% off our regular membership charge.

With your support, the National Museum of the American Indian can tell the story both past and present of Native life and culture in North, Central, and South America.

In just one visit to either of our Museums in Washington, DC, or New York City, you can watch a performance by traditional Native dancers... attend a lecture by a leading voice from the world of Native literature... spend an afternoon taking an informative audio tour of the Museum's distinctive grounds... and try your hand at Native crafts like pottery and beadwork. And for those who are unable to visit the museums in person, much of our extensive collection of more than 800，000 objects is cateloged on our website.

Only with your generosity can we share the Native story, awaken children to an interest in Native culture, and bring the Museum experience to people who can't travel to our Museums in person.

By joining the Museum today, you will take the first step in putting an end to the old stereotypes and long－held prejudices that have contributed to an incomplete picture of Native traditions and accomplishments.

Sincerely，

Kevin Gover

Director

阅读材料，回答问题。

材料一：自从德国打了败仗，“公理战胜强权”，这句话几乎成了人人的口头禅。……德国倚仗着他的学问好，兵力强，专门侵害各国的平等自由，如今他打得大败，稍微懂得点公理的协约国，居然打胜了。这就叫做“公理战胜强权”。——《独秀文存》

（1）材料一中，陈独秀评论的是哪一重大历史事件？为什么中国人非常关注这一事件？

材料二：1918年11月，北京大学举行集会。胡适在演讲中说：“这一次协商国所以能大胜，全靠美国的帮助。美国所以加入战国，全是因为要寻一个‘解决武力’的办法。”“如今且说美大总统所主张，协商各国所同声赞成的‘解决武力’的办法……”——彭明《五四运动史》

（2）材料二中的“协商国”主要指哪些国家？胡适为什么说“协商国所以能大胜，全靠美国的帮助”？美国提出了怎样的“解决武力”的办法？

材料三：在北京大学1918年11月所组织的演讲中，李大钊说：“我老老实实讲一句话，这回战胜的，不是联合国的武力，是世界人类的新精神。不是那一国的军阀或资本家的政府，是全世界的庶民。……这新纪元的世界改造，就是这样开始。资本主义就是这样失败，劳工主义就是这样战胜。”——《北京大学日刊》1918年12月6日

（3）结合所学知识，指出演讲中提到的“新纪元的世界改造”指的是什么？演讲反映中国思想界发生了什么变化？

（4）综合上述材料，分别概括陈独秀、胡适、李大钊的观点，并分析当时的国内背景。
