Hi, Joe, I wonder if you could do me a favor and tell the professor I've lost my voice.

嗨，乔，你能不能帮我一个忙，告诉教授我嗓子哑了。

I took out my shovel and took care of both our sidewalks and driveways because it was my turn to do a favor back.

我拿出铲子，打理好我们的人行道和车道，因为这回轮到我帮忙了。

Next time you see my family and someone's telling a joke, do yourself a favor: Make yourself invisible.

下次你见到我的家人，并且有人在说笑话，帮你自己个忙：变成隐形人吧。
