情况＃1 Jim与同伴交谈，并提醒他们有关将研究文件保存在云中的信息

Jim: I’m reminding everyone to save a copy of our research files on  cloud.

Hailey : I have already saved it on my hard drive.

Rose: I made copies as well on email.

Ben: It’s on my memory stick (USB/ flash drive) as well.

Jim : I understand that most of you would like to use your cloud storage for videos and photos, but then it’s also nice if we save our group files there. It’s better safe than sorry.

Mikko: Yes, I totally agree with Ben. Sometimes,  memory sticks and hard drives stop working because of virus.

情况2：Kyle与Ben谈了皮划艇时穿救生衣的重要性

Kyle: Hey Ben~ Don’t forget to wear your life vest before you go kayaking.

Ben: Wearing life vest will ruin my Instagram post

Kyle: I know that you know how to swim and that life vest doesn’t look good photos, but it’s better to be safe than sorry. The current’s strong right now.

Ben:Thanks for the concern Kyle. I will wear it later on.
