47.Tom,did it ever________ to you that you would be punished for cheating
on exams?
A) happen C) reflect　　B) occur D) strike
答案：B
译文：Tom,你是否曾经想过会因为考试作弊受到处罚了吗?
解析：occur to sb.浮现在某人的脑海中; 被某人想到.
occur 比较正式的用语,可用于具体或抽象的事物,通常指按计划或规律在较为确定的时间“发生”的事,在表示具体的事物时,可与happen换用.
如：I'm
afraid that this would occur during my absence.
= I'm afraid that this would happen during my absence.
恐怕这事会在我不在时发生.
但是,如果表示“某想法”出现在人的头脑之中,这时不能用happen代替.
Dose it ever occur to you that I am sometimes thinking?
我时不时想的那件事你是不是也曾再你头脑中出现过?
happen常指具体事件的发生,特别指那些偶然的或未能预见的“发生”.
比如：
New things are happening all around us.我们身边总有新事发生.
Happen还可表示“碰巧；恰好”之意.
如：It happened that I had no money on me.我刚好没钱了.
