but

or

so

for

考查連詞。句意：我以為我們音樂會遲到了，但是我們提前到達了那里。but 但是；or 或者；so 因此；for因為；兩個分句在意義上bu是轉折關系，故用but。故選A項。

the first time

every time

for the first time

for every time

考查時間狀語從句。句意：每次聽孩子對錯誤行為的辯解，聰明的父母都能分辨出他們是否在說真話。此處引導時間狀語從句，表示“每一次” 應用every time。the first time表示“第一次”，與語境不符；for the first time作時間狀語，不可引導從句；沒有for every time 的表達方式。故選B項。

You don't have to know the name of the author to find a book. You           find the book by the title.

need

can

would

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