Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is try­ing to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

When someone has deeply hurt you, it can be extremely difficult to let go of your anger. But forgiveness is possible - and it can be surprisingly helpful to your physical and mental health. In­deed, research has shown that people who forgive report more energy, better appetite (胃口) and better sleep patterns. "People who forgive show less anger and more hopefulness," says Dr. Freder­ic Luskin, who wrote the book Forgive for Good. "So it can help save on the wear and tear on our system and allow people to feel more energetic."

So when someone has hurt you, calm yourself first. Take a couple of breaths and think of some­thing that gives you pleasure: a beautiful scene in nature, someone you love. Don’t wait for an apology. "Many times the person who hurt you may never think of apologizing," says Dr. Luskin. "They may have wanted to hurt you or they just don't see things the same way. So if you wait for people to apologize, you could be waiting a very long time. "Keep in mind that forgiveness does not necessarily mean accepting the action of the person who upset you. Mentally going over your hurt gives power to the person who brought you pain. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person’s perspective 视角). You may realize that he or she-was acting out of ignorance (无知), fear 　– 　even love. To gain perspec­tive, you may want to write a letter to yourself from that person’s point of view.
