Question

请给以翻译并分析语法结构。

Being more realistic, the elderly have learned to focus on things that make them happy and let go of those that don't.

Answer 1

老年人更实际一些，他们懂得去专注于那些让他们开心的事情，并尽量忘却那些让他们不开心的事。

Being more realistic(being分词作状语), the elderly(主语) have learned to focus on things that（that引导定语从句，修饰things） make them happy and let go of those(those代指things) that (that引导定语从句， 修饰those) don't (don't 后面省略 make them happy).

Answer 2

Being more realistic是分词结构作原因状语，
the elderly 主语
have learned to focus on things that make them happy and let go of those that don't.是并列的两个动宾结构。
have learned to focus on things that make them happy
谓语 不定式作宾语 定语从句修饰things

let go of those that don't（make them happy ）
谓语 省略to的不定式作宾语 定语从句修饰those

分析定语从句 that make them happy
关系代词在从句中作主语 从句的谓语动词 宾语 宾语补足语

这句意思是：
因为更实际，所以老年人知道只去关注那些愉悦他们的事，抛开那些烦心事。

Answer 3

Being more realistic, the elderly(主语) have learned to focus on things （that make them happy 修饰things）and let go of those (that don't 修饰those，those又代指things).

Answer 4

老年人更实际一些，他们知道要专注于那些让他们开心的事情，抛开那些让他们不开心的事。
