Leon and Amy:
有时候有的人突然联系不上了，让人非常担心。今天我们来学习一下关于失联和迷失的英语。
失去联系，lost contact.迷失，lost.联系，contact.
我应该怎么联系你呢？请告诉我你的联系方式。How can I contact you? Please tell me your contact information.
你昨天去哪里了？我找不到你。Where were you yesterday? I could not find you.哪里，where.昨天,yesterday.找到，find.
有一部美剧《Lost》(《迷失》）我以前看过，不记得有几季了，第一季比较好看，后面的好像不怎么好看，我没继续追下去。
我曾经觉得很迷茫，不知道做什么。I once felt very confused, did not know what to do.曾经、一度，once.迷茫、迷惑，confuse.也可以说我曾经迷失了，不知道去哪里。I was lost, did not know where to go.
我曾经迷失了，现在找到了自我。I was lost, now I am found.
先找到你自己，再去找别人。Find yourself, before you find someone else.
昨天我找不到你，很担心你。I could not find you yesterday, I was worried about you.担心,worry, worry about.
你上个星期不在这里，我很想你。You were not here last week, I missed so much.这里，here.那里,there.想念，miss.有一首歌的歌词是：I miss you, I miss you, I miss you everyday...
请不要离开我,留下和我在一起。Please don't leave me, stay with me.离开，leave.留下，stay.
下课了，明天见。
