hold up an umbrella的用法和樣例：
例句
- He was wringing wet because he was caught in the rain without an umbrella.
由於未打傘在雨中行走，他全身濕透了。 - If it is a scorching day, I would pluck up my courage and take shelter under an umbrella, then dash as fast as I can inside the building for protection.
要真是太烈盛的陽光嘛，我會抖擻全身勇氣撐一派悠然自得姿態打傘，然後以最快速度躲入室內。
