英语语法 句子分析
The research suggests that even the most opulent,luxurious hotels seem to have underestimated the most basic needs of their customers - be they travellíng for work or ple的ure:the need to feel at home in surroundíngs which are both familiar and inviting.这句的 be之後我看不懂,请分析主谓宾出来

在这里是同位语从句,whether they should be .
whether和should省略后be前提,the need to feel...是同位语,进一步解释the most basic needs,which are both...是定语从句修饰surroundings.
再问： 怎麼看出是同位语从句整句来看，the research suggests 什麼呢？“ even the most opulent, luxurious hotels seem to have underestimated the most basic needs of their customers” even 作连词吗？这小段是可看成一句话还是从句
再答： 主句结构 the research(主语) suggests(谓语) that(宾语从句)，宾语从句中even不是连词，是副词，从句的主语the most opulent, luxurious hotels，谓语seem to have underestimated ，宾语the most basic needs of their customers，破折号后面是needs的同位语，起解释说明的作用。 还原句型：...customers, whether they should be...， whether 和should省略，be前提。首先根据意思判断：研究表明，即使是最奢华的旅馆，也会忽略顾客最根本的需求——他们是出差还是旅行，使周围环境显得安逸、舒适，像家一样的需求。
再问： 还原句型whether 和should省略，be前提。这是什麼语法，叫什麼？2.Even friends disagree sometimes.” “Even with the lights on full beam I couldn't see very far.” even作副词，怎麼看待这两句，第一句我觉得都不是句子。加分
再答： 1. 还原句型不是语法术语，我的意思是把完整的句子给你还原出来。把引导词whether加进去，就是whether they should be, 这里用了倒装，省略引导词和助动词。 2. Even friends disagree sometimes ， even是副词做状语。 Even with the lights on full beam I couldn't see very far. Even with the lights on full beam 是短语作让步状语， with + n + adj/介词短语。这个句子也可以还原：Even if/though the lights are on full beam, I couldn't... 你要分清楚状语和状语从句。even用作“即使、退一步说”的时候，让步状语或让步状语从句
再问： even用作“即使、退一步说”的时候，是让步状语或让步状语从句吗？怎麼分清楚状语和状语从句？Even with the lights on full beam 是短语作让步状语从句吗？
再答： 这里不是从句，是even+介词短语作让步状语。 从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，就像一个句子一样。所不同在于，从句须由一个关联词（connective）引导。根据从句语法功能的不同可分为：主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；定语从句功能相当于形容词，称为形容词性从句；而状语从句功能相当于副词，称为副词性从句。状语从句还可以分为条件状语从句、原因状语从句、地点状语从句、目的状语从句、让步状语从句、比较状语从句、方式状语从句、结果状语从句和时间状语从句。
