We still have to spend some money accessing (连接) the Internet at most time. Here comes a piece of good news.
A rich, powerful organization in the USA called the Development Media Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. They will send up hundreds of satellites into low Earth orbit (轨道) in 2015.
This is because they have made a survey and found that only 60% of the world's population have been able to get information on the Internet. And this is also because many countries are unable to offer people the necessary infrastructure (基础设施) to access the web.
We can expect to use free Wi-Fi everywhere in the near future.

【推荐3】When you write a text message or an email, you might put a smiling face or other picture at the end to make the message more fun. These pictures are emojis. The first emojis were on Japanese mobile phones in the 1990s. Later, they were used on Apple's iPhone and Android phones. Now they are everywhere!

Before emojis, there were emoticons. The word is formed by emotion and icon. Emoticons are made of the signs you can find on your keyboard, for example, :-) for a smile face or @):—for a rose. The first use of :-) dates back to 1982 and it was called "joke marker". Emoji is a Japanese word which means pictograph: e(picture) + moji(character). Emojis are real pictures, for example, or . According to Emojipedia, there are 1,851 emojis that can be used on mobile phones and other devices. There are all kinds of emojis, from faces and weather to things in the kitchen and animals.

In English, we have a saying: A picture paints a thousand words. For many people, an emoji is like a punctuation mark, or smiling at someone across the room. A written message is black and white, but an emoji adds emotions to our messages. It's like the tone of voice when we speak on the phone, or hand movements (gestures) used in conversation. Emojis are also changing the way we write. The more we use emojis, the less we use slang(俚语), such as LOL, IMHO or OMG.

When someone speaks and looks serious, we try to look serious, too, and when someone smiles, we smile as well. This is how we show empathy(同感) and make friends(and enemies!) But when we're online, we can't see the person's face and there's no emotion(情感).The invention of emojis changed that! Scientists in Australia have discovered that when we look at a smiley face online, the same parts of the brain start working as when we look at a real smiley face. Our mood changes, and we try to change our face to match the emoji. This is something which we are not born with, it's something we learn as we get older. Our brains have developed this ability over the last two or three years. This means that emojis created a new brain pattern in us!

【推荐3】Thinking about visiting Antarctica? If you are, then there are some things that you should know about before you go. Penguin highways, biosecurity and whale alerts are just the beginning! So here are things that you need to know before visiting the seventh continent.

When it comes to visiting Antarctica, there is pretty much no chance of avoiding such an expensive expedition (远征). Cruises (航行) booked at the last minute can go for as little as $4,000 and luxury cruises can go for as much as $ 50,000.

When people have asked about how cold it is in Antarctica, they are always told that it very rarely gets below freezing, and on the non-windy days, you could easily get around the ship in no more than a T-shirt. Cold wind is much more of a factor than the temperature itself, so as long as your clothing is windproof, the cold really shouldn’t give you any trouble at all. More importantly,   you need to respect the   penguin highways.   Yes, a penguin highway is exactly what it sounds like! The penguins follow the same paths up and down hills, resulting in discernible ( 可识别的) tracks in the snow that have been affectionately   ( 亲切地 )   named   “penguin   highways”.   These highways are the penguins favorite way of getting around, so it is important not to walk on or over them, and not to get too close.

A whale alert is exactly what you’d expect it to be. When whales are found by the ship, the captain will announce it over the loudspeaker to give anyone who wants to see the wildlife half a chance. Whale alerts can come at any hour of the day or night, so make sure you always have a battery and memory card in your camera.
