Sometimes, we hear stories of people behaving badly on airplanes. People _________ each other, as people feel stress. But _________ makes flying such a heated（激动的）time for our anger?

One of the main _________ is the crowded cabin（机舱）, according to Leon James, a scientist at the University of Hawaii. “When you _________ people together, there is a point at which they are no longer able to function appropriately, James said. People begin to feel unconnected（没有联系的）in this crowd. This can make them _________ control of their emotions（情绪）.”

Yet it’s not just the cabin that is the problem. Think of the _________ journey you have to take even before you board the plane. You have to arrive sometimes hours _________ a flight（飞行）. You have to pass security（安检）. Then you take off your shoes and coat. Then you put them back on. It can be very tiring.

Each of us should take responsibility（责任）for our actions, _________ airlines could be doing more to care for people. An easy step they can take is to ask questions to the _________. For example, “How many of you are going home?” or “How many of you have never been on a flight before?” It sounds simple, but according to James, it is more likely to make them feel __________ and friendly. How do you think we should make a friendlier flight?

Have You Got the Time?

People today are always thinking about the time.

There never seems to be enough time to do all the things we want to do. Believe it or not, there was a time before time was so important.

It was enough to know that the ________ was out in the sky. That meant it was daytime. During these days when the clock seems to control us, doesn’t that sound kind of nice?

Time can mean a lot of different things. That’s one way we know ________ important it is for us. We have so many words about it! The ________ amount (量) of time we can measure (测量) is called a second (秒). When you put 60 seconds together, you get one ________. If you take 60 minutes, you get one hour. The hands (指针) of the clock go all the way around twice in 24 hours, giving us one day.

If you want to look at time more than one day, you look at a calendar (日历) ________ a clock. There are about 30 days in one month. Some months have an extra day; February has a couple less. There are 12 months in one year. Time ________ stops.
