1. At first Bob was puzzled by Virginia's waving, but then it _____ his mind that she was trying to tell him something.
A. crossed B. passed C. occurred D. opened

[注釋]cross one's mind 想起：
1)A sudden thought crossed my mind.
2)It never crossed my mind that he might refuse the request. (我從來沒有想到他可能會拒絕這個(gè)請求。)

如用pass則應(yīng)加through, 例如：
When Jane did not come home by midnight, many terrible fears passed through Mother's mind. (=Mother thought of many things that might have happened to Jane.)

occur的用法如下：
1）That view of the case did not occur to me before. (對這個(gè)案件的那種看法以前我沒有想到過。)
2）It occurred to her that she might adopt a homeless child.(她想到，她可以收養(yǎng)一個(gè)無家可歸的孩子。)

關(guān)于“想起”的以上三種表達(dá)法考生務(wù)必弄懂熟記。這些詞組和句形不僅在詞匯測試中經(jīng)常遇到，而且在短文寫作時(shí)也可以使用。
