词语辨析：

1. anywhere 与 somewhere 两者都是不定副词。

anywhere 在任何地方，常用于否定句和疑问句中。I can’t find it anywhere.

somewhere 在某处，到某处，常用于肯定句。 I lost my key somewhere near here.

2. seem + 形容词 <看起来….. You seem happy today.

3. decide to do sth.决定做某事 < < <They decide to visit the museum.

decide + 疑问词 + 动词不定式 <He can not decide when to leave.

4. start doing sth = start to do sth. 开始，可与 begin 互换。He started doing his

homework.

但以下几种情况不能用 begin .

1)创办，开办： He started a new bllkshop last month.

2)机器开动： I can’t start my car.

3)出发，动身： I will start tomorrow morning.

5. over 介词，多于，超过，在…以上（表示数目、程度）= more than

My father is over 40 years old.

在 …之上，与物体垂直且不接触，与 under 相反。 There is a map over the

too much 太多，修饰不可数名词，修饰动词作状语。<

分辨三者的口诀：

too much, much too, 用法区别看后头：<

much 后接不可数， too 后修饰形或副。

too many 要记住，后面名词必复数。
