[辨析] sound, voice & noise
sound，noise和voice这三个名词都可表示“声音”，但有区别：
(1) sound可以指人或动物发出的声音，或物体碰撞的声音。这个词的使用范围很大。可以说，大自然的任何“声音”都可以用sound。如：
At midnight he heard a strange sound.
半夜里他听到一种奇怪的声音。
We couldn’t hear a sound here.
在这里我们一点声音也听不到。
(2) noise常指不悦耳、不和谐的嘈杂声。如：
The noise of traffic kept him awake.
车辆的喧闹声使他睡不着。
We were woken up by noises in the night.
我们夜间被噪声吵醒了。
(3) voice一般指人的声音，说话、唱歌；谈笑都可用voice。

那女孩嗓音很美。
They are talking in low voices.
他们正小声交谈。
注意：
sound和noise不仅能指人的声音，还可以表示别的动物发出的声音；
而voice除了有时可指鸟的声音外，很少表示其它动物的声音。

[辨析]
too many, too much和much too
这三个词语的主要区别在于它们的中心词以及它们所修饰的词不同。三者之中的前一个词都是修饰词，用来加强语气，后一个词是中心词。因此，在使用时只需要考虑后一个词的用法就行了。
(1) too many的中心词是many, 用法与many相同，用来修饰复数可数名词。如:
He's got too many questions to ask you.
他有很多问题要问你。
They bought too many eggs yesterday.
昨天他们买了太多的鸡蛋。
(2) too much的中心词是much, 用法与much相同，用来修饰不可数名词。如:
We both have too much work to do.
我们俩都有很多工作要做。
She spent too much money on clothes.
她花太多钱买衣服。
The teacher told him not to spend too much time playing games.
老师叫他不要花太多时间玩游戏。
I'm afraid that I've given you too much trouble.
恐怕我太麻烦你了。
另外， too much还可作名词性短语，用作宾语; 也可作副词性短语，在句中用作状语，修饰动词。如:
You've given me too much.
你给我的太多了。
I have too much to do every day, so I am very busy.
我每天都有很多事情要做，所以我很忙。
He talked too much at the meeting, didn't he
他在会上讲得太多了，是吗？
Don't eat too much.
不要吃得太多。
(3) much too的中心词是too, 用法与too相同，用来修饰原级形容词或副词。如:
You're walking much too fast. Slow down.
你走得太快了，慢点。
I'm afraid that this cap is much too big for me.
这顶帽子我戴恐怕太大了。

A
[考题链接]
( ) He eats ______ food, so he is _______ fat. A. too many; too much
B. too many; much too C. too much; too much
D. too much; much too
解题思路：根据该题句意“他吃了太多的事物，因此他很胖”可知，该题正确答案为D。
D
Health is very important to us. We should eat more vegetables and fruit instead of _______ rich food. (2006 黑龙江哈尔滨)
A. too much B. much too
C. very much
解题思路： too much 意为“太多”，用来修饰不可数名词；而much too 的含义是“(实在)太……”，用来修饰形容词和副词。分析比较三个选项，由题中的关键信息rich food 可知正确答案为A。
A
—The meat is ______ delicious.
—Yes, but don't eat ______. (2013广西玉林)
A. too much; too much
B. much too; too much
C. too much; much too
D. much too; much too
【解析】考查副词的用法。too much太多，修饰不可数名词；much too太，非常，修饰形容词或副词原级。根据delicious可知要用much too来修饰，意为非常美味，第二空根据句意可知别吃得太多。所以选择答案B。
B

A. too much B. too many
C. much too D. many too
