1st Google Classroom Homework: Crusades 十字军东征 (Due Wednesday 11:59 p.m.)

Please read the textbook Chapter 14 from page 376-385 and answer the following on a Google Doc or on a piece of loose leaf paper and take a picture of it and submit to Google Classroom. 请阅读 课本十四章 376-385 页数， 然后用一到两个句子解释以下词汇的历史重要性。 可以直接用Google Doc 或者在一张纸上写， 然后拍张照片提交到Google Classroom.
same rule goes for online learning：if I see two HWs with exact same answers, BOTH of you will receive 0. 远程教学功课的规定是一样的， 如果有两位同学的答案是一模一样的， 则两人都会拿到0分。

I will be entering your attendance on Wednesday. If you don't have a post here or on Google Classroom by Wednesday 11:59 p.m., you will be marked absent.
