真诚的希望各位朋友帮我解答下这两句英语

Question

我现在背诵新概念英语第三册59课,其中遇见两句难懂的句子现在需要请求各位朋友帮我解答下!both of which are essential in turning out and throwing away, and sentiment这句话书上翻译为,，这二者是清除无用的东西必不可少的因素；另一原因是感情因素!这里的in turning out 是什么意思,难道是因素的意思吗\???throwing away, and sentiment又怎么理解呢??? to save buying these two requisites这句话书上翻译为,省得日后去买!似乎这样翻译,脱离了原文的意思???

Answer 1

【全句是： people also accumulate things for two other reasons, lack of physical and mental energy, both of which are essential in turning out and throwing away, and sentiment.】

essential是必不可少的意思，”必不可少的因素“是根据essential翻译的。lack of physical and mental energy和sentiment（感情）就是那两个reasons，both...这句是插入的。可以先不看这一句，结构就很清楚：people also accumulate things for two other reasons, lack of physical and mental energy and sentiment。人们积攒东西还有两个原因，身心无力和感情因素。

插入句中的：turning out 和throwing away对应“清除无用的东西”，turn out是把东西腾出来，throw away是丢东西。
