解析試題分析:考查定語從句。從結(jié)構(gòu)判斷cases后是定語從句，從句是主謂賓結(jié)構(gòu)所以從句用關(guān)系副詞引導(dǎo)，case是抽象名詞，應(yīng)該用where引導(dǎo)定語從句。而A選項(xiàng)why引導(dǎo)定語從句時(shí)需放在先行詞reason后；C選項(xiàng)as引導(dǎo)定語從句時(shí)先行詞前需有the same，such，so等修飾；while不引導(dǎo)定語從句，所以正確選項(xiàng)為B。句意：你能想出這樣一些情況嗎，司機(jī)顯然懂得交通規(guī)則，但是根本不遵守這些交通規(guī)則。
考點(diǎn)：考查定語從句。
