3. 【答案】B

【知识点】unless、if…not=unless引导的条件状语从句
4. 【答案】D
【解析】考查连接词。句意：在美国和其他的一些国家，务必不要让十四岁以下的孩子坐在前排座位上是司机的职责，除非他们系好某种安全带。A. while 当……的时候，引导时间状语从句；B. even 甚至；更；C. until 一直；D. unless 除非，如果不，引导条件状语从句。分析句子结构可知为条件状语从句，故选 D。

6. 【答案】D
【解析】此题考查状语从句。句意：我额外多带了一些钱。因为如果我看到适合买给我儿子当礼物的东西的话。就可以买了。in case 常被误译作“以防”，使大家误认为其后从句中只能接坏事儿，其实 in case 是双重逻辑结构，即等于“if + because”，先以从句为条件，若条件为真，则再以从句为原因，发生主语动作结果；若条件为假，则主句无用。翻译时，in case 应被译作“因为如果……所以 + 主句”，so that 除了表示“以致于”的结果外，还和 in order that 共享“为了”的意思表目的。这其中表目的是强干扰项。题目中多带钱的目的不是从句中的 found something，而应该是 could buy my son birthday gift。
