3. OK. That can be fixed. 好的，我来修理它。
fix 修补，修理。

我的表停了，需要修理了。
辨析：repair, mend与fix
这三个动词都可以用来表示“修理”某一事物，使其能恢复到原来的形状或形态的意思。
1) repair的对象范围很广，从房屋、道路、机器到日常生活必需品，是使受到一定损失或失灵的东西恢复其形状或功能。
Who has repaired the broken leg of the table 谁把桌子的断腿修好了
Language points
2) fix用于需要重新“调整”物体的结构，把松散的部件固定结实，将分离的物体各部分装配起来。在美国口语中，它与repair无太大区别。
Can you fix the broken chair
你能修理那把坏了的椅子吗？
fix指“修理”时，是个非正式的用语，它的基本含义是将某物“固定”在某一地方。 fix可用来指“修补”或“整理”任何出了毛病的东西，使用范围较repair广。
I am going to fix my bicycle tomorrow.
我准备明天修理自行车。

thousands of 成千上万的

当这些词与具体数字连用时, 习惯上用单数，而且其后也不接介词of 。
He was prepared to pay two million. 他愿意支付200万。
More than a hundred people were injured.有一百多人受了伤 。
但是，当这些词后面的名词有了the，these, those等特指限定词修饰时，或其后接的是us, them这样的人称代词时，此时必须用介词of。
About three hundred of them have left there.
他们当中约有300人离开了那儿。
Language points
拓展：hundred，thousand 及 million的具体用法
2) 用复数的场合
当这些词不与具体数字连用，而是表示不确定的泛指概数时，则不仅要用复数，而且要接介词of, 然后才能接名词。
The sun was shining. Thousands of people were lying on the beach.
阳光灿烂，数以千计的人躺在海滩上。
A careless mistake cost the company millions of pounds.
一个粗心的错误使公司蒙受数百万镑的损失。
Language points
分析:一些长的句子需要按照意思的群落（即“意群”）适当断开、稍加停顿（即“停顿”），断开的几部分都具有相对完整的意思。按照一般语法结构，可划分为以下意群单位：
(1)短句 (2) 名词短语 (3) 介词/不定式/分词短语 (4) 动词短语 (5) 主谓结构 (6)动宾结构 (7) 系表结构 (8) 动状结构 (9)主句-从句。
