1) URead：体验英语
What is airport check in?
You register your arrival at an airport, etc
You report your arrival, esp. at an airport or hotel, so that you can get the service you are paying for
Airport check in is the procedure by which an airline or hotel formally registers the arrival of a passenger for a flight or a guest for a stay.
Airport check-in is normally handled by an airline.Passengers usually hand over any baggage they do not wish or are not allowed to carry-on to the aircraft's cabin and receive a boarding card before they can proceed to board their aircraft.
When a passenger checks in at the airport, he will show his passport or ID card and his air ticket at the check-in counter and hand over his luguagge and receives his boarding pass.
2) UTalk： “学”“用”同步“使用英语”
要提请注意的训练要点是：这几段英语向给我们所传递的信息，不是让我们去用中文把它们逐字逐句翻译一遍，也就是“使用中文”。它们提供给我们的信息是要我们锻炼“使用英语”造句表达的能力，也就是“用英语输入，再用英语输出”，“学”“用”同步“使用英语学英语”。我们要训练的是这个。否则，这些用于“使用英语”训练的英语就失去了训练价值和训练意义。
你读了里面出现的这么多让人感觉非常有用的、你刚开始一下没想到的词汇和句子，你有没有一种“哦，我知道了!看到了好多有用的机场登机词汇!”的顿悟?现在，我们可以根据这些英语有所取舍的“学”“用”同步“使用英语”了：
读到一再重复的词汇You register your arrival at an airport, etc/You report your arrival, esp. at an airport or hotel, so that you can get the service you are paying for/ Airport check in is the procedure by which an airline or hotel formally registers the arrival of a passenger for a flight or a guest for a stay等英语时，你的“反应”是什么?
不会是“这些英语的中文是什么呀?”吧?
我们应该这么来训练自己“学”“用”同步“使用英语”：
Well I know when we say airport check in, we can say we register our arrival at an airport,or we can also say we report our arrival at an airport so we can get the servicewe are paying for.
也就是说，我们不说check in这个表达，我们也可以说register our arrival at the airport或report our arrival at the airport这样的表达。
能这么练就我们“使用英语”的能力，我们对check in的英语表达就丰富起来、多样化起来了。
其实，你学习英语这么多年，最缺乏的就是在这个能力上得到他人的系统训练，而不是让他人教你“办理英语登机用英语怎么说?”从而学会和记住airport check in 这个单词而已。
