题组一 基础过关
1. before 句意，她关心自己的学生要超过美心自己的身体健康，这就上为什么两年后她才进行乳腺癌治疗，
此处表示“在她接受乳腺癌治疗之前过去了两年”，故用 before 引导时间状从句，表示“过了多久才……。”
2.unil 句意:直到他们的老师回来，他们才开始工作。此处 not… until...表示“直到........”.,引导时间状语从句。
3. whether 句意: 越来越多的人愿意在网上买自己想要的东西，我就是其中之一。无论我需不需要，我都会
情不自禁地买东西。根据语境可以推断出此处考查让步状语从句，whether...or not 意为:无论..还....。
4.that 句意: 正如我们看到的那样，养成一个好的习惯如此重要.以至于我想介绍一种好的学习习惯，即每天
