4. other 改为 others 。不定代词 other 指另一个， 而 others 指另一些。

3. where 改为 which/that 或删去 where。此为定语从句， 先行词 place在从句中作 find 的宾语， 只能用关系代词 which 或 that 或省略。

2. them 改为 it。依据上下文， 前句 a chocolate cake 为可数名词单数， 后边的代词显然用 it， 而不是 them。

1. want 后加 to。want to do sth. 为固定搭配。

10. comfortable 后加 with。comfortable with 意为“与……自在/愉快”。例如：

　She feels comfortable with those who speaks English。她和讲英语的人谈话觉得很自在。

　My brother Tom was very selfish when he was a little boy.

　He did not want share things with other people. For 1._______

　答案及解析

9. friend 前加 a。friend 为普通可数名词单数， 其前应加不定冠词 a。

8. clean 改为 cleaning。应与 cooking， doing， washing 一致， 作介词宾语。

7. any 改为 some。any 一般用于疑问句、 否定句、 条件从句中， 而 some 一般用于肯定句中。此处为祈使肯定式， 故用 some。

6. 删去 for。因为 change 作“改换”讲时为及物动词。如： Can you change me one yuan note?你能兑换一元零钱给我吗?而 change for作“转换车到……”解。如： Where should you change for Guilin? 你在什么地方转车到桂林去?

5. life 改为 lives。这是考查名词的数， life 是可数名词单数， 句子主语用的是they， 与其一致应用lives。
