仔细阅读
46. A it is unfair to those climate-venerable nations.
细节题，题目定位词除了Paris climate agreement之外还有一个重点定位词critical，问作者为什么对此协议是批判态度，在文中并不是很明确找到。第一段交代这项协议的具体时间内容等，第二段才谈到作者的批判态度。即we reveal just how deep this injustice runs,作者认为这是不公的，this injustice指代前两句，遭遇气候伤害的国家(少数4%国家)却承担一大半全球温室气体排放的责任，这是不公的。injustice=unfair
47.C They hardly pay anything for the problem they have caused
细节题。定位词“free-riders”，这个词在第三段，冒号后解释说，通过大量温室气体排造成严重问题，同时却不用承担气候变化的代价。In other words后面的句子也在解释同一件事情。原文出现cost和problem 在正确答案中以pay和problem复现。
48.C They have to bear consequences they are not responsible for
细节题，定位词“forced-riders”和second-hand smokers，定位在第四段，who are suffering from climate impacts despite having scarcely contributed to the problem.这些forced-riders没有助长全球变暖这个问题但却要承担气候问题的不良后果。答案为近义词替换：bear consequences=suffer from impacts，be not responsible for=scarcely contribute to
49.B There is no final agreement on where it will come from
细节题，定位词“100 billion”，定位到第7段，该段出现核心考点“however”，说明整个段落对这笔资金的使用是转折后的评价，即负评价。答案应该选择B或C两个包含负评价的词之一(均出现no)。其中B There is no final agreement on where it will come from是对应转折后面的两个不足中的第二个不足，即对There is also very little detail on who will provide the funds or importantly who is responsible for their provision的同义改写，即协议中对谁提供资金及谁承担募集资金的责任没有做明确说明，探讨资金来源而非资金花费的方式。
50. D putting in effect the policies in the agreement at once
细节题，定位词urgent action 对应第8段(倒数第二段)，there must urgently be a meaningful mobilization of the policies outlined in the agreement即动用协定中拟定的政策，近义词替换put in effect(生效)=mobilization(动用)，及原词复现。

passage 2
51.C Teenagers’ mental problems are often too conspicuous not to be observed.
句子理解题。考查句子意思与上下文相同或相反，此处上下文无转折词，应读下一句话：Their risky behaviors can alert parents and teachers that serious problems are brewing.其意思是青少年的一些危险举动—喝酒吸毒等—能警告父母老师大事不妙了。对应答案青少年的心理问题是非常显而易见得观察到的。serious problems指心理问题，conspicuous behaviors指破折号中的危险举动的概括改写。
52. D Many hitherto unobserved youngsters may have psychological problems
细节题。对应第二段转折but a new study：有一些青少年(睡眠不足不爱活动等行为)可能会有着同样的得精神疾病(psychiatric symptoms)的危险，正确答案对此处是概括型改写，那些行为对应着unobserved youngsters，也与上文的易观察的行为有着转折关系，psychological problems对应psychiatric symptoms。
53. B Their behaviors do not constitute a warning signal.
细节题，定位词invisible risk,对应第三段，直接给出原因句：because their behaviors are not usually seen as a red flag. 同义替换warning signal=red flag
54.A They are almost as liable to depression as the high-risk group
细节题，顺序原则+定位词invisible group，至定位句but the invisible group wasn’t far behind the high-risk set,with more than 13%of them exhibiting depression. 定位即答案，两句话均表示，这一群体和高危青少年群体在表现抑郁症的比例上几乎不相上下。
55. B it provides new early-warning signals for identifying teens in trouble.
细节题，Carli和significance 对应最后一段it provides new early-warning signs for parents teachers and mental healthcare providers.
