Question

I guess we’ve already talked about this before but I’ll ask you again just _______.

A．by nature

B．in return

C．in case

D．by chance

Answer 1

C

試題分析：考查介詞短語：A. by nature天生B. in return 做為回報(bào)C in case以防D. by chance偶然，句意：我想我們以前談過這個(gè)問題，但以防萬一我會(huì)再問你一遍。選C。
點(diǎn)評(píng)：介詞的考查重在積累。解題技巧:  1）明確詞意  所選答案要符合句子意思；2）歸納比較平時(shí)要特別重視收集歸納比較同義詞、近義詞和相似詞的異同，牢記它們的用法。
