1. 她双手托着腮帮子，不知道在想什么。
with hands holding her chin, her mind went away.

2. 他脑袋那么大，脖子那么短，结果头简直就象是架在肩膀上。
with a head so big and a neck so short, it looks like he has had his head directly upon his shoulders.

3. 别用你那手指戳我的腰好不好？
don't poke me on the waist with your finger!

4. 先把鳞刮干净了，再把肚子剖开，一定记得要把内脏掏了，胆千万别弄破。

5. 夜深了，月儿爬上了梢头。
it was late at night. the moon rose above the tree tops/branches.

6. 一到夏天，知了就没命地叫“知了，知了...”吵死人了。
once in summer, cicadas would cry "to know, to know..." as crazy, making me extremely annoyed. 

7. 秋老虎刚过，天就一天比一天凉了。
the hot autumn is just over and the weather's getting cooler day by day.

8. 眼泪模糊了她的双眼，她眨了眨眼睛，泪水劈劈啪啪地掉了下来。
tears blurred her eyes, after a blink, beginning to drop down.
