It is December 25th, 2050. The people in the city are all celebrating Christmas. I’m the mayor of our city. My citizens* and I are holding a big party under the sea, though you wouldn’t believe it. But please do not feel excited, you should feel sad because we have to live under the sea. Because of the pollution, the earth has been completely destroyed, from top to bottom. The atmosphere* has no oxygen* and moisture*. As a result, the plants are burned by the strong sunlight with a great number of harmful rays. Of course, none of them are still alive. Not only no green, but also the temperature reaches about 121℃ all day even in winter because there is too much CO2 circling the earth.

  On the land, there is no life. Luckily, the sea is not destroyed by human. So, we have to move into the sea. At the bottom of the water, people have built many new cities. There is a lot of advanced* equipment* in each city. Computers are used to control all the machines, even the people’s life. We can also make the seawater into fresh water. There are two machines making oxygen. If they stop working for only one minute, more than 10 million people will die.

The population of our city is over 30 million and, of course, it is quite crowded. We have lots of high buildings and bridges. The roads are wide, too. Our cars are miniature* UFOs, don’t be surprised, it is true. At the bottom of the sea you can’t see anything, because there is no light all day. However, we have advanced lighting equipment so that we can see the “sun” under the sea. Of course, the advanced lighting equipment is very expensive. And if it doesn’t work, we can see nothing under the sea. What should we do then?

Asking for information or help is a very common and necessary activity, especially when we visit a foreign country. So knowing how to ask for information politely is important. In English, "Where are the restrooms?" and "Could you please tell me where the restrooms are?" are similar requests—both are correct English, but the first could sound rude. It's important to use correct language, but sometimes this alone is not enough—we need to learn how to be polite when we make requests.

In English, just like in Chinese, we change the way we speak when talking with different people. The expressions you use might depend on whom you are speaking to or how well you know them. If you say to your teacher, "Where is my book?" this will sound rude. But if you say, "Excuse me, Mr West. Do you know where my book is?" your question will sound much more polite. On the other hand, it might be alright to say "Where is my book?" in some situations, perhaps with people you know well.

And you would not usually say, "Peter, lend me your pen. " A very direct order like this can sound rude in English. Usually in English polite questions are longer and include extra language, such as "Could you please...?" or "Can I ask...?" It sounds more polite to say, "Peter, could you please lend me your pen?" Sometimes we might even need to spend some time leading in to a question or request. For example, if you stop a stranger in the street, we might first say, "Excuse me. I wonder if you can help me. " or "I'm sorry to trouble you but," before asking them for help.

It might seem that speaking politely is more difficult than being direct, and in a way this may be true. However, in order not to offend people, learning about the language etiquette is just as important as learning grammar or vocabulary. And doing this will also help you become better at English, or any other language you wish to speak.
