答案：
1.because 改为so. 前面是因，后面是果。
2. send改为sent 时间是yesterday，应该用过去式。
3. 去掉第一个for prepare 为直接准备，prepare for是间接准备。
4. took改为take take和前面的come为平行结构，是省略了to的动词不定式。
5.was 改为were there be 结构的主语在其后，cold drinks是复数，谓语动词用复数。
6. talking改为talked 三个动作是连续不断的动作，不是分词短语做状语。
7.they改为we 人称用错，我们感到我们是世界上最快乐的人。
8. quick改成quickly 应该用副词修饰动词passed。
9.clock前加the clock后有on the wall限定。
10.正确。
