On an airplane, a spacecraft or a man-made satellite, there is usually an installed device called the “black 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 reveals a shocking fact that many aircrafts met their disasters only because 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 shuttle Challenger exploded soon after launch, because a screw on it was a bit loose!

An idea thus occurs to me: if a human being was equipped with a similar device, tracking all the subtle inner changes that had taken place over time, the results could astonish the world. Newspapers carry no few such stories from day to day-cases of graft or bribe-taking（行贿或受贿）,how an innocent man was robbed and killed, and so on. A fatal error, committed by a criminal at a particular point in his life, may have arisen from a small quarrel or out of envy. The number of those who were born evil and deliberately sent themselves to the “gallows（绞架）”is in fact extremely small. The disappointment towards the last moment of their life is on different from a struggle against an aircraft crash!

Behave properly in small matters and take best care of the soul-this, I insist, is the message from that mysterious box planted deep inside human souls.

1．The first two paragraphs are mainly about .

A．the mysterious box inside human souls.

B．the causes of the disasters.

C．the fatal mistake of space shuttles.

D．the function of the black box.

2．The underlined phrase “a similar device” in Paragraph 3 refers to .

A．a useful device B．a black box

C．an installed device D．an important instrument

3．According to the text, which of the following is NOT true?

A．Most of us were born kind, but those evil by nature are not in small numbers.

B．Many crashes should have been avoided if pilots had been careful.

C．Some small errors can even cause a long-lasting regret.
