【4】At the moment of graduation from Senior High School, recalling the past, we cannot be too grateful to teachers for their guidance, to classmates for their help and to the school for her tolerance.

【解析】

【1】

考查It makes sense(that)…句型。分析句子可知，真正的主语是不定式to hold onto principle and distinguish right from wrong, 用It makes sense (that)…这一句型中it作形式主语，条件状语是in any circumstance；再根据其它汉语提示，故翻译为：It makes sense in any circumstance to hold onto principle and distinguish right from wrong.

【2】

考查动词indicate及which引导的非限制性定语从句。分析句子可知，主语为从句more and more people in developing countries can earn more than 1.9 dollars a day，谓语为indicates(表明)，宾语为从句they are living above the extreme，此处that省略了；which引导的非限制性定语从句指代前边整个句子，再根据其它汉语提示，故翻译为：More and more people in developing countries can earn more than 1.9 dollars a day, which indicates they are living above the extreme.

【3】

考查as+adj./adv.+as结构。分析句子可知，句子由表示转折关系的并列连词but连接，but之前的句子主语为the pictures posted on Wechat Moments，谓语为make，宾语为people，宾语补足语为envy their friends’ lives。but之后的句子主语为their real lives，谓语为might not be，表语为as attractive as the pictures showed us。as+ adj./adv. +as表示同级比较，第一个as后加形容词attractive，第二个as后加比较对象。再根据其它汉语提示，故翻译为：The pictures posted on Wechat Moments often make people envy their friends’ lives very much, but their real lives might not be as attractive as the pictures showed us.

【4】

考查cannot…too结构。分析句子可知，主语为we，系动词为be，表语为grateful，be grateful to“对……心存感激”，to后加感激的对象teachers for their guidance, classmates for their help and the school for her tolerance，时间状语为at the moment of graduation from Senior High School。用cannot…too表示“再……也不为过”，这一双重否定表肯定的句型用来强调；再根据其它汉语提示，故翻译为：At the moment of graduation from Senior High School, recalling the past, we cannot be too grateful to teachers for their guidance, to classmates for their help and to the school for her tolerance.
