#考研英语# 长难句每日一句

But if the district is essentially giving a pass to students who do not do their homework because of complicated family lives, it is going riskily close to the implication that standards need to be lowered for poor children.

1.本句是复合句。
2. 主句主干为It is going riskily close to the implication, that引导的同位语从句解释说明implication。
3. If引导的条件状语从句中又包含一个who引导的定语从句，修饰students。
