Okay, guys, have you spotted it? It is " keep it down". "Keep" is a factitive verb which means make. "It" refers to something that disturbs someone else and it's used as object. "down" is a adverb which means low and it's used as complement of "it". "Keep it down" is very easy to think of it's meaning if we put it in a situation. 直译是：是它下降。把声音一步步的压下来，那么环境安静多了，不打搅大别人。因此它的意思就是：安静点儿，小声点儿。

【短语积累】
1 keep it down 安静点儿2 turn the music off 关掉音乐【咬文嚼字】
1 Would you keep it down? 翻译：你能安静点吗?
要点：would 是will 的过去式，表示一种婉转的请求，译为：请。
Would it be convenient for you to leave tomorrow? 明天走你方便吗? 例句点拨：这句话中很明显说话者是希望那个人走，可是为了不很明显表露自己的想法，不伤害别人的感情，在此用would 就是话中还有话，就是叫别人明天走。
2 I can turn this music off. 翻译： 我会关掉音乐的。
要点：can 在这里是表示说话者同意对方的要求。在句中因为b 开音乐吵到a了，a 教b安静点，b同意a的要求，把音乐关掉。

All right, how many have you caught . 【JULIET，你怎么读的和录音的不一样呀?】是的，没错，我的跟录音有很大区别，录音发的音是标准发音，我发的是美国人在日常生活中的真正发音。我们经常听不懂美剧中的句子和美国人说话，问题就在这里了。Now let's look at them one by one.
1 would you [wudju:]
当前一个单词的最后一个字母是d，后一个单词的第一个字母是 j 是， 美国人将其连读为 [dj]
2 keep it down ['ki:bi'daun]
Keep 以爆破音而且是清辅音结尾，it 以原音开头，前面的辅音[t]与后面的原因[i]连读, 就成了[ti]，由于清辅音在原音面前可以浊化为浊辅音，因此[ti]就读为[di]. It 是以爆破音[t]结尾, down 是以爆破音[d]开头，前面的爆破音就是去爆破。因此 it down 就读为 [i'daun].整个短语就读为 ['ki:bi'daun]，重音在第一和第三个音节。
3 can [k?n]
Can 在肯定句中是弱读的，在否定句中才是重读。
4 music off ['mju:zig?:f]
Music 是以爆破音而且是清辅音结尾，off 以元音开头，前面的辅音[k]与后面的元音连读, 由于清辅音在原音面前可以浊化为浊辅音。
