• A global network of networks 由网络组成的全球网络

• The wires which connect computers together 连接计算机的电线

• Another word for the World Wide Web 万维网的另一个词

Answer explanation

Correct Answer: B.

Answer A: This answer is not quite right because it makes it sound like the internet is just one small part. The internet is actually made up of many networks all connected together.

Answer C: This answer is too simple. It only talks about the wires, but the internet is much more than that. It includes all the connections and information shared between computers.

Answer D: This answer is a common mistake. Many people think the internet and the World Wide Web are the same, but they are not. The World Wide Web is just one part of the internet.

So remember, the internet is like a big map that connects many smaller networks around the world!

正确答案 B.

答案 A：这个答案不完全正确，因为它让人觉得互联网只是其中的一小部分。实际上，互联网是由许多网络连接而成的。

答案 C：这个答案过于简单。它只提到了电线，但互联网远不止这些。它包括计算机之间的所有连接和信息共享。

答案 D： 这个答案是一个常见错误。许多人认为互联网和万维网是一样的，其实不然。万维网只是互联网的一部分。

所以请记住，互联网就像一张大地图，连接着世界各地的许多小网络！

• Connect networks together 将网络连接起来 ✔

Answer explanation

The first three answers are correct!

1. Connect networks together: This means routers help different networks join together to make a bigger network, which is important for the internet to work.

2. Send information around the internet: Routers help direct messages and data so they can travel across the internet to where they need to go.

3. Choose the quickest route for information: Routers decide the best and fastest way for information to travel based on different factors.

The last two answers are not correct because routers don’t keep networks safe or store websites. This shows that we need to learn more about how networks work!

前三个答案都是正确的！

1.         将网络连接在一起： 这意味着路由器可以帮助不同的网络连接在一起，组成一个更大的网络，这对互联网的运行非常重要。

2.         在互联网上发送信息： 路由器帮助引导信息和数据，使它们能在互联网上到达需要到达的地方。

3.         为信息选择最快捷的路径： 路由器根据不同的因素决定信息传输的最佳和最快路径。

后两个答案不正确，因为路由器不能保证网络安全或存储网站。这说明我们需要更多地了解网络是如何工作的！
