　　下面小编跟大家一起了解考研英语长难句每日一句解析分享，希望对大家的学习有所帮助。
　　all the subjects were drawn from a population of European extraction, care was taken to see that all subjects, friends and strangers, were taken from the same population.
　　译文：尽管所有的对象都选自欧洲裔的人群，但还是刻意小心确保包括朋友和陌生人在内的所有研究对象都从相同的人群中选取。
　　分析：本句是一个主从复合句。主干结构是： care(主语) was taken(谓语)。不定式结构“to see that引导的宾语从句”做目的状语;宾语从句中，主语是all subjects, friends and strangers做all subjects的同位语, were taken做谓语，介词短语from the same population做状语。句首是由Though引导的让步状语从句;从句的主语是all the subjects ，谓语是were drawn，介词短语from…extraction做状语。
