脑筋急转弯：1，If two old friends run into each other, what do they say?

1. If two old friends run into each other, what do they say?
答案：Ouch! （这其实没有什么道理，就是两个人撞一块，会说Ouch,“疼！”的意思。

2. What did the ghost use to project his voice?
答案：Loud spooker.

原因：本身应该是Loud speaker，因为Ghost都是Spook（可怕的），所以用Loud Spooker，Loud Speaker的意思是扬声器。

3. How do you start an insect race?
答案：One, two, flea, go!
为什么呢？本来应该是One, two, three, go!意思是1，2，3开始！而Flea正好是一种昆虫（Insect，就像题目里说的）也就是跳蚤。所以这么说。

其实这些都不算脑筋急转弯，不过有点像。网上一般都可以查到。顺便问一下，你这些从哪里来的？

1. They might probably say "Hi".
2. Eject insecticide!! (如何使昆虫开始赛跑？当然是喷杀虫剂啦)
3. 还没想出来，这句英文好像不是很通顺，没看懂，想到了再来更新。。

1.Hi,long time no see, you are still a baldhead!(because they are rival in love)

3.Become to an insect!

2. because they are afraid to tread by human or others,they are a see-through.
