背景说明

　　这九句，非常有用，你看到任何朋友都可以用这些话向他们打招呼。
(1) Great to see you. 很高兴见到你。
美国人见到朋友，最常说的话就是Great to see you.这种说法很多。
Great to see you.                   = Wonderful to see you.
= Good to see you.                = Glad to see you.
= Nice to see you.                  = Pleased to see you.
(2) So good to see you. 看见你真好。
这句话是It's so good to see you的省略。so 用来将强good的语气。
(3) What's going on? 有什么新鲜事？
美国人见了面会说 What's going on? 其实不一定真的在问“有什么事？”只是在打招呼。
What's going on?= What's up? = What's happening?
(4) What's up today? 今天有什么计划？
What's up? 当成惯用语来看，意思是“发生了什么事？”加上today，意义完全不同。在此today= for today. 表示“今天有什么计划”。
(5) What are you doing? 你今天要做什么？
 这句话的字面意思是“你正在做什么？”可以引申为其他意思，要看当时的情况和语气来决定。
(6) You look great.  你看起来很棒。
根据美国人的习惯，见到朋友，就会说 You look...最常用的是You look great.
You look great.= You look cool.
(7) You look high-spirited. 你看起来精力充沛。
这句话很接近我们中国人常说的“你看起来很有精神。”这句话也可以说成You look in high spirits.
(8) You look like you're ready for anything. 你看起来已经准备好做任何事了。
美国人最喜欢说I'm ready或You're ready之类的话，因为美国人一切讲究事先准备。 这句话也可说成You look like you're ready. 或 You look like you're ready for any challenge.

背景说明
   
       称赞别人是一种美德，日常生活中，每天都有机会用。所以对老师的称赞有两个单元，背好以后，可以举一反三，用在其他地方。
(1) You're an excellent teacher.
这句话中文译成“你教得很好。”比译成“你是个很棒的老师。”要好。
(2) Your material is great.
凡是老师选的课本或教材，都叫material或teaching material。注意：material 作“教材”解释时，是不可数名词。
(3) You're never dull.

此句意思是“你从不乏味。”引申为“和你在一起绝不会无聊。”
You're never dull. = You're never boring. = You're interesting.
(4) You're full of pep.
pep [pep] n. 精力，活力
这个字来自于pepper  n. 胡椒。吃了胡椒，或闻了胡椒，都会刺激感官，就是“活力”的意思，full of pep就是“充满了活力”。
(5) You keep us on our toes.
on one's toes 可能是源自赛跑起跑时，踮着脚尖，准备听枪声，那个时候一定是“准备好了”、“有活力的”、“有警觉的”。
You keep us on our toes.的意思是“你使我们有警觉。”在此引申为“你让我们上课专心听讲。”
(6) I like your style.
这句话字面的意思是“我喜欢你的风格。”在这里是指“我喜欢你的方式。”或“我喜欢你教书的方式。”
(7) You do a good job.
You do a good job. 你教得真好。（语气谦卑，可用于学生对老师说。）
You're doing a great job. 你表现得很好。（适合老师对学生说。学生对老师这样说，就不太礼貌了。）
