今天我们继续学习“Just”。请在对话中合适的地方加入“Just” 例如：A: Hi there. Do you have a minute? (你好！你有时间吗?). I want to tell you some good news (我想告诉你一些好消息). B: Really? Hold on a second (真的吗？等我一下). I need to close the door (我去关门). Add "just" to these sentences (请加入“Just”). A: Do you have a minute? I just want to tell you some good news . B: Really? Hold on just a second。 I just need to close the door. 现在请在以下对话中加入“Just”  A: Hello (你好). B: Hi, dad. It's me. (你好，爸爸，是我！). Is mom there? (妈妈在吗?). A: Yeah. But hold on a second (在，但是稍等一下). She's upstairs (她在楼上). I need to call her (我要去叫她). A: Is this a good time to talk? (现在说话方便吗?). B: Sure. Could you hold on a second? (当然，能稍等一下吗?). Let me turn down the TV (我去把电视音量调低). So, what's up? (怎么了?). A: Well, I was calling to ask your advice about something (我给你打电话是来征求你的建议). A: Hi, I'm calling to say hello (我给你打电话是想向你问好). B: Oh, hi. Listen, can I call you back? (我能等会儿给你回电吗?). I have to finish something （我要完成一些东西). 请在合适的位置填入“Just”，并把你的答案评论在下方，我们下次课见！
