  Passage 2

  Passage 1

If you still can’t figure out what the heck a bitcoin is…

  Q19: Some people say if kids didn‘t happen to go to school, they’d all be out in the streets。 My reply is no。 They wouldn‘t。 First, even as schools stay just what they are, children would spend at least some time there because that’s where they would be likely to find their friends。 Q20: Second, schools wouldn‘t stay the way they are。 They’d get better。 Because we would have to start making them what they ought to be right now。 Last, if we give children a little help, those who did not want to go to school, could find other things to do, since many children now do during their holidays。 Q21: There is something easier we could。 We need to get kids out of the school buildings to give them a chance to learn about the outside world at first hand。 In Philadelphia and Oregon, plans are being drawn up for public schools that won‘t have any school buildings at all。 That will take the students out into the city and help them to use it and its people as a resource。 In others words, students, perhaps in groups, perhaps independently, will go to libraries, museums, exhibitions, radios, and TV stations, meetings, businesses and laboratories to learn about their world and society at first hand。 A small private school in Washington is all ready doing this。 It makes sense, and we need more of it。

  In today’s job market, it is not a common for job seekers to send applications for many positions。 That is lots of time and lots of work to organize。 Certainly, you can’t want to waste your precious hours on following the developments on the fashion, and miss the important deadlines, confuse interview times or forget to follow up a result。 Accordingly, managing our work search properly is just as important as identify the job opportunities and send your applications。 If you familiar with Microsoft Excel or a similar program, creating a table is a simple and effective way to keep track your job applications。 If the excel isn’t used as drinking a cup of tea, don’t worried。 You can create a table in Microsoft。 Google is another tool to help you to organize your work effectively。 If you have a G-mail account, you can create a safe and send tables in addition to read a document like your cover letter and resume。 You can also link up with Google calendar to make sure you make top with the important dates。 Clearly, there plenty of days to keep track of search and to make efforts to simplify your job search well paid off。 Nevertheless you should always focus on the quality not the quantity。 Only you apply the position you are qualified for, and make each application count, personalizing each cover letters and updating your resume。

The apple’s yours! I can’t give you another apple because I don’t have any left. I can’t control it anymore. The apple left my possession completely. You have full control over that apple now. You can give it to your friend if you want, and then that friend can give it to his friend. And so on.

  Q21: What does the speaker say is the easiest thing we could do?

So that’s what an in-person exchange looks like. I guess it’s really the same, whether I’m giving you a banana, a book, or say a quarter, or a dollar bill….
But I’m getting ahead of myself.

  解析:

Back to apples!

金沙官网 2

Now say, I have one digital apple. Here, I’ll give you my digital apple.
Ah! Now it gets interesting.

How do you know that that digital apple that used to be mine, is now yours, and only yours? Think about it for a second.

It’s more complicated, right? How do you know that I didn’t send that apple to Uncle Tommy as an email attachment first? Or your friend Joe? Or my friend Lisa too?

Maybe I made a couple of copies of that digital apple on my computer. Maybe I put it up on the internet and one million people downloaded it.

As you see, this digital exchange is a bit of a problem. **Sending digital apples doesn’t look like sending physical apples.**

Some brainy computer scientists actually have a name for this problem: it’s called the double-spending problem. But don’t worry about it. All you need to know is that, it’s confused them for quite some time and they’ve never solved it.

Until now.

But let’s try to think of a solution on our own.

  篇章结构清晰,有明确的起承转合词,如second,因此,考生在做题时不容易听漏信息。重点把握试听一致,根据选项完整性可以做出题目。

Ledgers

金沙官网 3

Maybe these digital apples need to be tracked in a ledger. It’s basically a book where you track all transactions — an accounting book.

This ledger, since it’s digital, needs to live in its own world and have someone in charge of it.

Say, just like World of Warcraft. Blizzard, the guys who created the online game, have a “digital ledger” of all the rare flaming fire swords that exist in their system. So, cool, someone like them could keep track of our digital apples. Awesome — we solved it!

  Passage 3:

Problems

There’s a bit of a problem though:

  1. What if some guy over at *Blizzard *created more? He could just add a couple of digital apples to his balance whenever he wants!

  2. It’s not exactly like when we were on the bench that one day. It was just you and me then. Going through Blizzard is like pulling in Uncle Tommy(a third-party) out of court(did I mention he’s a famous judge?) for all our park bench transactions. How can I just hand over my digital apple to you, like, you know— the usual way?

Is there any way to closely replicate our park bench, just you-and-me, transaction digitally? Seems kinda tough…

  Before there was the written word, there was the language of dance。 Dance expresses love and hate, joy and sorrow, life and death, and everything else in between。 (22) Dance in America is everywhere。 We dance from Florida to Alaska, from Harison to Harison and coast to coast。 We dance at weddings, birthdays, office parties or just to fill the time。 (23) “I adore dancing,” says Lester Bridges, the owner of a dance studio in a small town in Iowa。 “I can‘t imagine doing anything else with my life。“ Bridges runs dance classes for all ages。 ”Teaching dance is wonderful。 My older students say it makes them feel young。 It’s marvellous to watch them。 For many of them, it‘s a way of meeting people and having a social life。” So why do we dance? (24) “I can tell you about one young couple,” says Bridges。 “They arrive at the class in a bad mood and they leave with a smile。 Dancing seems to change their mood completely。”

The Solution

金沙官网 4

What if we gave this ledger — to everybody? Instead of the ledger living on a Blizzard computer, it’ll live in everybody’s computers. All the transactions that have ever happened, from all time, in digital apples will be recorded in it.

You can’t cheat it. I can’t send you digital apples I don’t have, because then it wouldn’t sync up with everybody in the system. It’d be a tough system to beat. Especially if it got really big.

Plus it’s not controlled by one person, so I know there’s no one that can just decide to give himself more digital apples. The rules of the system were already defined at the beginning. And the code and rules areopen-source—you know, kinda like the software used in your mom’s Android phone. Or kinda like Wikipedia. It’s there for the smart people to contribute to, maintain, secure, improve on, and check on.

You could participate in this network too and update the ledger and make sure it all checks out. For the trouble, you could get like 25 digital apples as a reward. In fact, that’s the only way to create more digital apples in the system.

  So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier, a dance teacher says,“Dance, like the ryhtem of a beating heart, is life。 Even after all these years, I want to get better and better。 I keep practicing even when I‘m exhausted。 I find it hard to stop! Dancing reminds me I’m alive。”

I simplified quite a bit

…but that system I explained exists. It’s called the Bitcoin protocol. And those digital apples are the “bitcoins” within the system. Fancy!

So, did you see what happened? What does the public ledger enable?

  1. It’s open source remember? The total number of apples was defined in the public ledger at the beginning. I know the exact amount that exists. **Within the system, I know they are limited(scarce)**.

  2. When I make an exchange I now know that digital apple certifiably left my possession and is now completely yours.** I used to not be able to say that about digital things. **It will be updated and verified by the public ledger.

3)** Because it’s a public ledger, I didn’t need Uncle Tommy(third-party**) to make sure I didn’t cheat, or make extra copies for myself, or send apples twice, or thrice…

*Within the system, the exchange of a digital apple is now just like the exchange of a physical one. It’s now as good as seeing a *physical apple leave my hand and drop into your pocket. And just like on the park bench, the exchange involved two people only. You and me — we didn’t need Uncle Tommy there to make it valid.

In other words, it behaves like a physical object.

But you know what’s cool? It’s still digital. We can now deal with 1,000 apples, or 1 *million apples, *or even .0000001 apples. I can send it with a click of a button, and I can still drop it in your *digital *pocket if I was in Nicaragua and you were all the way in New York.

I can even make other digital things ride on top of these digital apples! It’s digital after-all. Maybe I can attach some text on it — a digital note. Or maybe I can attach more important things; like say a contract, or a stock certificate, or an ID card…

So this is great! How should we treat or value these “digital apples”? They’re quite useful aren’t they?

Well, a lot of people are arguing over it now. There’s debate between this and that economic school. Between politicians. Between programmers. Don’t listen to all of them though. Some people are smart. Some are misinformed. Some say the system is worth a lot, some say it’s actually worth zero. Some guy actually put a hard number: $1,300 per apple. Some say it’s digital gold, some a currency. Other say they’re just like tulips. Some people say it’ll change the world, some say it’s just a fad.

I have my own opinion about it.

That’s a story for another time though. But kid, you now know more about Bitcoin than most.

  22。 What does the passage say about the dance in America?

  23。 What do we know about the Lester Bridges dance studio?

  24。 What happened to the young couple after they attended last Bridges in class?
