1. 刚刚；勉强；仅仅
    You use barely to say that something is only just true or only just the case.

    e.g. Anastasia could barely remember the ride to the hospital...
           阿纳斯塔西娅几乎记不起来怎么去的医院。
    e.g. It was 90 degrees and the air conditioning barely cooled the room...
           当时气温达到了90度，空调也不能让房间凉快多少。

2. 刚刚…（就）
    If you say that one thing had barely happened when something else happened, you mean that the first event was followed immediately by the second.

    e.g. The Boeing 767 had barely taxied to a halt before its doors were flung open...
           这架波音767刚刚停住，它的舱门就弹开了。
    e.g. Barely had the bulldozers started when Museum of London archaeologists swooped.
           推土机刚一启动，伦敦博物馆的考古学家们就蜂拥而至了。
