In order to make sure he would be able to attend the meeting, I called him two weeks _ _______.
A. in advance
B. all at once
C. at a time
D. over time
题目解答
答案
A. in advance
解析
本题考查介词短语的辨析，核心在于理解每个选项的含义及适用语境。关键点在于确定“two weeks”后接的短语需表达“提前”的意思，从而选出最符合句意的选项。
句意分析：句子中的“to make sure he would be able to attend the meeting”表明“提前联系”是必要动作，因此空处需填入表示“提前”的短语。
选项辨析：
- A. in advance：意为“提前”，符合句中“提前两周联系”的语境。
- B. all at once：意为“突然”，与句意无关，排除。
- C. at a time：意为“每次”，表示频率或数量，不符合“提前”的含义，排除。
- D. over time：意为“逐渐”，表示时间推移中的变化，与“提前”无关，排除。
综上，A选项“in advance” 是唯一符合句意的答案。
