Flying is a fast way to travel. But it is a big headache for some people. They can’t help worrying about things like “Is it dangerous if we don’t change our mobile phones to airplane mode (飞行模式)?” Here are some interesting facts about flying.

Why are plane windows round?

It’s for safety. As the airplane flies higher and higher, the atmospheric pressure (气压) outside gets lower and lower. During the flight, the pressure inside the plane becomes greater than the pressure outside. When this happens, square windows can break. That’s because having different pressures inside and outside puts stress on the corners of square windows. But rounded corners can spread the pressure more evenly (均匀地) across the window’s surface, making it less likely to break.

What happens when a phone isn’t in airplane mode?

Some passengers believe mobile phones and tablets(平板电脑) need to be turned off because they can bring the plane down. However, this is not true. If you don’t change your phone to airplane mode, pilots and air traffic controllers may hear unpleasant sounds in their headphones. This makes it harder for them to communicate. So it’s still best to put your devices (设备) in airplane mode.

【解析】

文章大意：本文介绍了关于乘飞机的有趣的事实。飞机的窗户是圆的，它能使飞机内部的压力更均匀地穿过窗户的表面，从而减少破裂的可能性。当手机不在飞行模式时，就会干扰飞行员和空中交通管制员们之间的沟通交流。

1.

考查动词。根据第一段最后1句“Here are some interesting facts about flying”，可知本文主要谈论一些关于飞行的有趣的事实。由空前的介词about考虑此处填动词-ing形式，故答案为flying。

2.

考查名词。根据第三段第1句“It's for safety”，可知飞机的圆窗是为了安全。故答案为safety。

3.

考查介词。根据第三段第3句“During the flight, the pressure inside the plane becomes greater than the pressure outside”，可知在飞行过程中，飞机内部的压力比外部的压力大。此处介词inside表示“在……内部”，故答案为inside。

4.

考查介词。根据第三段第3句“During the flight, the pressure inside the plane becomes greater than the pressure outside”，可知在飞行过程中，飞机内部的压力比外部的压力大。此处介词outside表示“在……外部”，故答案为outside。

5.

考查动词。根据第三段第4句“When this happens,square windows can break”，可知当这种情况发生时，方窗可能会破裂。由动词不定式作宾语补足语，考虑此处填动词原形形式，故答案为break。

6.

考查动词。根据第五段第1句”Some passengers believe mobile phones and tablets need to be turned off because they can bring the plane down”，可知一些乘客认为，手机和平板电脑需要关闭，因为它们可以使飞机坠毁。原文用短语bring down 表示”坠毁”之意，此处可以同义转换为动词crash，故答案为crash。

7.

考查形容词。根据第五段第2句“However, this is not true”，可知这种情况不是真实的。故答案为true。

8.

考查名词。根据第五段第3句“If you don't change your phone to airplane mode, pilots and air traffic controllers may hear unpleasant sounds in their headphones”，可知如果你不把手机换成飞行模式，飞行员和空中交通管制员可能会在耳机里听到不愉快的声音。此处sounds表示“响声”，为可数名词，考虑填复数形式，故答案为sounds。

9.

考查名词。根据第五段第3句“If you don't change your phone to airplane mode, pilots and air traffic controllers may hear unpleasant sounds in their headphones”，可知如果你不把手机换成飞行模式，飞行员和空中交通管制员可能会在耳机里听到不愉快的声音。此处headphones表示“耳机”，为可数名词，故答案为headphones。

10.

考查名词。根据第五段第4句“This makes it harder for them to communicate”，可知这使得他们更难交流。原文用动词不定式to communicate表示“交流”之意，此处由空前的物主代词their可知要转换为名词communication，故答案为communication。
