据说这个过桥谜题只有5%的人能解开，是不是迫不及待地要试试你是不是那5%的人呢？那赶紧开始吧！

You are doing an internship at a laboratory in a secluded area

（你在偏远山区的一间实验室里实习）

You need to escape the horrible zombies.

（你必须躲避可怕的僵尸）

The janitor, the lab assistant, and the old professor are with you.

（门卫、实验室助理、老教授和你一起）

There is only one way to flee, across the bridge over deadly river.

(逃生的路径只有一条，要越过死亡之河上方的那座桥梁）

Here are the facts: You can make it to cross the bridge in one minute.

（情况是这样的：你可以在一分钟之内成功过桥）

The lab assistant needs two minutes.

（实验室助理需要两分钟）

The janitor is a bit slower and takes five minutes.

（门卫慢一点，需要五分钟）

And the professor needs 10 whole minutes, because he needs to hold tight to the ropes of the bridge every step of the way.

（而教授需要整整十分钟，因为他走每一步都得紧抓绳索）

According to the professor’s calculations, the zombies will reach you in just 17 minutes.

（根据教授的计算，僵尸们在仅仅十七分钟内就会追上你们）

You have only got until then to cross the bridge and cut off the ropes on the other side。

（你只有那些时间来过桥并从另一端切断绳索）

Sadly, the bridge can only take two people at a time.

（不幸的是，桥一次只能承载两个人）

Also, it’s also dark that you can hardly see anything.

（此外，天色十分黑，你几乎什么都看不到）

The lantern you quickly took along only lights up a small area.

（你匆忙带上身上的灯笼只能照亮一小块地方）

Can you manage to get everyone across?

（你有办法让每个人都通过吗）

Remember, only two people can cross the bridge together, and one of them has to hold the lantern. There is only one lantern.

（记住，只有两个人一起过桥，而其中一个人得提灯笼。只有一个灯笼）

The people waiting at either side of the bridge can do without the lantern.

（在桥任一侧等待的人可以不用灯笼）

Solution:

The secret is to minimize time by letting the two slowest people cross the bridge together, and the two fastest hold the lamp.

（秘诀是让两个最慢的人一起过桥好让时间减到最少，然后最快的两个人提灯笼

So first, you need to cross the bridge with lab assistant. After two minutes, you, being the fastest, can bring the lantern back to the other side.

（所以首先你需要和实验室助理一起过桥。两分钟之后，身为最快的那个人的你就可以带着灯笼回去另一侧）

So, it has taken three minutes so far. Fourteen minutes left until the zombies are back.

（那么目前已经用掉三分钟了，在僵尸回来前还有十四分钟）

Next, the professor and the janitor take the lantern and cross the bridge together. That will take 10 minutes. 

（接下来，教授和门卫提着灯笼然后一起过桥，那会用掉十分钟）

Now you’ve got 4 minutes left, and you are on the wrong side of the bridge. 

（现在你还剩四分钟，而你在桥不对的那一侧）

Luckily, the lab assistant, the second-fastest is waiting on the other side. She takes the lantern and runs across to you. 

（幸好，实验室助理，第二快的人，她在另一侧等着。她提着灯笼然后跑过去你那边）

Now you can use the remaining two minutes to cross the bridge together.

（现在你们可以用剩下的两分钟一起通过桥梁）

As soon as you’ve arrived on the other side, you can cut off the rope just in time.

（当你抵达另一侧时，你就可以及时将绳索剪断了）
