答案解析：

36. 答案：quality
解析：good quality是“质量好”，名词短语修饰models。此词不要误写成quantity“数量”或动词qualify。

解析：根据前面的have，可知此处为动词的过去分词，所以不要漏写词尾d。
38. 答案：value
解析：value for money意为“性价比”。

解析：familiar常与with搭配，表示“熟悉……”，注意此词的拼写，也不要写成family或similar。

解析：此处需要一个与“估价”有关的词，由前面的being可知为过去分词。拼写要注意双写s及词尾的-ed。
41. 答案：recommend
解析：此处需谓语动词，由主语researchers可知为动词原形。
42. 答案：perhaps
解析：根据上下文可知此处需副词。
43. 答案：additional
