考查連詞。句意：我以為我們音樂(lè)會(huì)遲到了，但是我們提前到達(dá)了那里。but 但是；or 或者；so 因此；for因?yàn)?；兩個(gè)分句在意義上bu是轉(zhuǎn)折關(guān)系，故用but。故選A項(xiàng)。

for every time

考查時(shí)間狀語(yǔ)從句。句意：每次聽(tīng)孩子對(duì)錯(cuò)誤行為的辯解，聰明的父母都能分辨出他們是否在說(shuō)真話(huà)。此處引導(dǎo)時(shí)間狀語(yǔ)從句，表示“每一次” 應(yīng)用every time。the first time表示“第一次”，與語(yǔ)境不符；for the first time作時(shí)間狀語(yǔ)，不可引導(dǎo)從句；沒(méi)有for every time 的表達(dá)方式。故選B項(xiàng)。

考查情態(tài)動(dòng)詞辨析。句意：你不需要知道作者的名字就能找到一本書(shū)。你可以按書(shū)名找到這本書(shū)。A.must必須，一定；B.need 需要；C. can可能；可能；D.would愿意。根據(jù)句意可知，此處表示一種客觀的可能性，應(yīng)使用情態(tài)動(dòng)詞can。故選C項(xiàng)。
