上将该项涂黑。   ，

On an—airplane，a spacecraft or a man-made satellite，there is usually an installad device called the“biack box ”Made of a special kind of material．it would remain unbroken，even if the entire craft were blown to pieces．The box records some important data,which provide clues as to what changes had occurred before the real thing came along and help to discover the causes of the

disaster．

The black box．Therefore, becomes the last piece of evidence left.More often,it reveal a Schocking fact that many aircrafts met their disasters only beeanse of a simple but fatal mistake

Some hadn’t been supplied with sufficient fuel；others crashed due to a bird flying in their paths.In many cases。the pilot had been tired．In 1986，the famous US space siadttle Challenger exploded

soon after launch, because a screw on it was a bit loose!
