一位逻辑学家被人绑架,绑匪向他家人索要赎金,后来发现他家一贫如洗,由于不想随意撕票,绑匪头子决定给他一次逃生的机会。
他说:“在你面前有且只有两扇门,一扇通向死亡,一扇通向自由,你可以选择一扇门离开。为了帮助你决定或选择,我的两个助手之一会和你在一起,并且只允许你对他说一句话,他会回答真或假(对或错),你可以据此作出判断。然而我必须警告你,我的两个助手一个完全说真话、另外一个则总是说谎。”说完绑匪头子哈哈大笑,并率众离开,只留下他的两个助手之一。
绑匪头子认为这样省却了自己做一个杀生决定的麻烦,只不过给了逻辑学家一个求生的赌注机会。但是,逻辑学家在他哈哈大笑的同时也在心里暗自窃喜,因为对于逻辑学家来说,不存在什么赌注机会,自己是可以必然求生的。接着他向留下来的助手说了一句话,按助手的回答,准确无误地走向了自由之门。
请问:他向留下的助手提的是什么问题?

In morden society,roads extend everywhere,you can go everywhere that you want to go.And owning a car is a good thing.It makes going out more convenient and comfortable.It travels so fast that it can save a lot of time of waiting for a bus.
However,owning a car can also bring us some trouble.First,it release remaining gas into our air,this pollute our beautiful environment. and it cause many species vanish from the earth,such these animals as dinosaur,indigene.In addition,many society problems appear follow increase of the car.In a big city,many travel accidents occur because of plenty of cars. These problems influence our society largely.
Nevertheless,the disadvantages of cars can be solve.We have the ability to improve and produce new cars to suit different tastes.Driving a car is a part of morden living.Nowadays China's economy has been developing rapidly ,so I am sure that cars will be widely used by more and more Chinese in their daily lives.

摘要: 1.不要看到别人的回复第一句话就说:给个代码吧!你应该想想为什么。当你自己想 出来
再参考别人的提示,你就知道自己和别人思路的差异。
2.别小家子气,买本书几十块都舍不得,你还学个P。为了省钱看电子书,浪费的时间绝对
超过书的价值。当然如果查资料,只能看PDF。
3.学习新的开发软件时,一定要看帮助手册。买的书不够全面。刚接触一个软件,什么都不
懂,就盲目的问东问西,让人看起来很幼稚。
4.不要蜻蜓点水,得过且过,细微之处往往体现实力。
5.把时髦的技术挂在嘴边,还不如把过时的技术记在心里。

Attitudes toward opportunity vary from person to perso.Some people hold that it isn't important for us to get success if you work hard.In contrast,other people insist that opportunity for one's success is important but not decisive.and I agree with the second opinion.
Last year,I wanted buy a computer and didn't have enough money.What can I do for it?I was searching something that can help me.At final,opportunity appeared--our scholarship.I got it and got my computer!Maybe I could get it in another way,but this way is more efficient.So we have to admit that opportunity is an important factor for our success.
This year,I wanted buy a mobile telephone ,and also opportunity appeared.but I failed to get the schalorship.I missed the opportunity.But I brought a mobile phone thourgh the money I did work. Therefore,we should agree that opportunity is not decisive to get success.
There are lots of examples like this around us ,or in out histor.Those can proved that opportunity is one of the most important factors for our success.

有甲乙丙三人,丙叫甲和乙各伸出一只手,给甲乙二人手心中各写了一个数字,并告诉他们:
“你们两个手心中的数字,都是比一大且比四十小的数字;我的两手的手心也各有一个数字,我这两个数字之和,就是甲手心中的数;我这两个数字之乘积,就是乙手心中的数。你们二人不妨互相猜猜对方手心中的数是什么。我要看看你们两个都是不是推理高手!”
甲和乙当然都是推理高手~~~
甲想了想,说:“我敢肯定,乙不知道我手心中的数是什么!”
乙听后,也想了想,说:“嗯,我到现在也没法确定你的数字。”
这时甲却说:“呵呵,不过,听了你的这句话,我就已经知道你手心中的数了!”
乙不甘示弱地笑道:“你别得意,听了你的这句话,我现在也知道你手心中的数是什么了!”
果然,他们两个互相都猜对了!
那么,到底甲乙丙手中的4个数字都是什么呢?

Online love is becoming more and more popular these year,especially among the young.It has both postive and negative sides.
For one thing, it offers a new way to make friends.In morden society, people communicate with each other less than before,and it cause many problems.but because of online love,it may reduce the problem.
But for another ,it causes many youth go online with aboundant,and it waste plenty of time which is important for our youth.
In my opinion,I am for the negative side,because true love is based on long-term and honest intercouse which needs face to face communication.Online love may be the first step but never the last.
