What can we learn from the passage about the Paris Agreement?

参考解析：

推理判断题。根据文章第二段“The U.S. is now the only major country in the world not committed to the accord, which aims to keep global temperatures from rising more than 3.6 degrees Fahrenheit (2 degrees Celsius) above pre-industrial temperatures”可知，它的目标是防止全球气温比工业化前上升超过7.2摄氏度，因此A项错误；根据文章第一段第一句“the United States officially withdraws from the Paris Agreement, the landmark international accord to keep climate change in check and limit future greenhouse gas emissions”可知，美国正式退出巴黎协定，这是一项具有里程碑意义的国际协定，旨在遏制气候变化，限制未来的温室气体排放，因此B项正确；根据文章第一段最后一句“because the drafters of the Paris Agreement made it hard to leave and relatively easy to join”可知，巴黎协议的起草者让他们很难离开，而且相对容易加入，因此C项错误；根据文章第六段“Now, the U.S. has officially become the first and only signatory to leave the pact, joining Iran and Turkey as the only major emitters to eschew the international deal”可知，现在，美国正式成为第一个，也是唯一一个退出协定的国家，加入伊朗和土耳其的行列，成为唯一一个回避国际协定的主要排放国，因此D项错误。故选B。
