2.分析in fact前后的句子可以看出，他们是转折的关系，在所有选项中，只有while可以表转折、对比。

3.while意思是“趁……”。as 引导时间状语从句表示“当...的时候”、“在... 期间” 时，该从句的谓语通常是那些表示动作意义的动词，而不能是 be(是，在),have(有)，like(喜欢)，belong(属于)等表示状 态或静态意义的动词。

【易错点】:D有学生会错误地把这句话当作非限制性定语从句了

【备考提示】:分清句子类型，识别连词性质，选择正确答案

2. 本题考查连词的用法。由语境分析可知，此处表达的意思为“在公共汽车将要停止的过程中不能下车”，能表达此意的连词只有while，表示“在……过程中”

3.when 在此的意思不是“当……的时候”，而是“尽管”、“虽然”的意思。
