句意：1870年9月中旬，在一个凉爽、繁星点点的夜晚，四个男人在火洞河边的营火前放松，这里现在是怀俄明州的西北部。
后文为介词in的宾语，is前缺主语，指物，主语用what引导宾语从句，作介词in的宾语，故填what。
2.【2024浙江1月卷】If most of their customers are happy to buy larger quantities,that’s____39____they’ll promote.But that leaves the solo(单独)customers out of pocket and disappointed.【39题详解】考查名词性从句。
句意：如果他们的大多数客户都乐意大量购买，那他们就会推广。
在表语从句中缺少宾语，且是指事物，所以应用连接代词what。
故填what。

年高考第一轮复习语法专题之名词性从句
年高考第一轮复习语法专题之名词性从句名词性从句【互动导学】【知识梳理】在复合句中起词名词作用的句子叫名词性从句 (Noun Clauses）。
名词性从句的功能相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句可分为、表语从句、宾语从句和同位从句。
引导名词性从句的连接词1）连接代词： who, whose, whom, what, which有词义，在从句中必须充当句子成分，如主语、表语、宾语或定语等。
2）连接副词： when, where, why, how有词义，在从句中必须充当成分，只能作状语。
3）连接词： that, whether, if, as ifthat 无词义，在从句中不充当成分，做宾语时可省略；if ，whether，as if虽有词义，但在从句中不担任成分。
注意：连接代词与连接副词在句中不再是疑问词，因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。
根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。
4）连接代词：whatever, whoever, whomever, whichever 5）语序名词性从句都必须与陈述句语序相同，即“主语＋谓语”。
【导学】一：主语从句：在复合句中其语法作用是主语的句中，叫主语从句。
【知识点】1：主语从句位于句首e.g. （1）That he finished writing the composition in such a short time surprised us all.（2）Whether we will go for an outing tomorrow remains unknown.(注意：不能把whether改为if，因为if不能引导主语从句)（3）Whatever you did is right.（4）Who will be our monitor hasn't been decided yet. （5）What caused the accident remains unknown.1（6）Which of the two is better remains to be seen. （7）When we willstart the work is important.【知识点】2：为了避免句子头重脚轻，用it作形式主语，主语从句放在句末。
