Question

Ann is so careful that she always goes over her exercises to ________ there are no mistakes.

[　　]

A．look for

B．make sure

C．find out

D．think about

Answer 1

答案：B
解析：

解析：據(jù)題意，要檢查自己作業(yè)的目的是確保不犯錯(cuò)誤。make sure是固定詞組，意為“確信”。故選B。

提示：

啟示：sure是形容詞，意為“確信的，把握大的，一定的”。如：I'm sure that he is right. 我深信他是正確的。 She isn't sure where she puts it. 她不確定把它放在什么地方了。 be sure to do sth.主語為人或物，表示說話人推測“一定，必然會”。 be sure of (that) 主語為人，表示主語感到“有把握，確信”。如：It is sure to rain. 天準(zhǔn)會下雨。 She is sure of her answer.她對自己的回答有把握。
