★★★★★★★★★★★★

3. Super-Earths and Life 超級地球與生命
https://www.edx.org/course/super-earths-and-life

What life lies beyond our small world? Thirty years ago we only knew about nine planets; today we know of thousands nearby stars. In this course, students will learn about exoplanets, which ones might be the best candidates for harboring life, and why those planets are of the greatest interest. Combining concepts in astronomy and biology which have rarely been put together before, the class is an excellent introduction to one of the most interesting eras in astrobiology; today.

In this class, students will identify their own style of learning and find out how that style fits into the ever-changing landscape of education. Later lectures focus on how to apply that knowledge to leadership, organizational structure, and the future of learning.

你如何學習？你為什麼要學習？你能說出三個可以分享答案的人嗎？在本課程中，學生將辨認自己的學習風格，並了解該風格如何適應不斷變化的教育環境。後段課程聚焦於如何將這些知識應用於領導力、組織結構和未來。

★★★★★★★★★★★★

6. American Government 美國政府
https://www.edx.org/xseries/harvardx-us-government

The federal government of the United States can seem like a far off and alien system, one which acts in strange ways; but it is a powerful force in the life of every American. To not understand how it works, and your place in it as a citizen and voter, is to be an irresponsible citizen. This course introduces students to the function, history, institutions, and inner workings of American government. No previous study or understanding of American politics is required, making the course ideal for non-American students who want to understand what exactly is going on there.

美國聯邦政府看起來像個運作方式奇特，遙不可及的陌生體系。但在每個美國人生活中這是一股強大的力量。如果不了解它是如何運作的，以及自己作為公民和選民在其中所處的位置，會成為不負責任的公民。本課程向學生介紹美國政府的職能、歷史、機構及其內部運作。無需對美國政治的事前學習與了解，使該課程成為想要了解美國到底發生了什麼的非美國學生的理想選擇。

★★★★★★★★★★★★

7. Humanitarian Response to Conflict and Disaster 人道主義對衝突與災難的應對
https://www.edx.org/course/humanitarian-response-to-conflict-and-disaster

We live in a world with staggering humanitarian crises, and responses to them that are often lacking. In this class, students will ask questions on how to deal with humanitarian disasters through the case studies of Zaire, Syria, The Balkans, and elsewhere. The history of humanitarian responses, and the frameworks that those responses past and present operate in, will be covered as well, and students will be challenged to ask if they remain sufficient.

我們生活在充滿令人震驚的人道主義危機的世界中，而對這些危機往往缺乏應對。在本課程中，學生將通過薩伊、敘利亞、巴爾幹地區和其他地區的案例研究，提出有關如何應對人道主義災難的問題。本課程還將涵蓋人道主義應對的歷史以及過去與現在的應對所運行的框架，並且挑戰學生去提出這些應對是否足夠。
