It is impolite to inquire of_________ affairs of others．

[　　]

Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.

Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill.

Today many governments have special departments which protect customers and workers．In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

【小题1】The main topic of the passage is ___________________________________________.

A policeman was questioning 3 blondes who were training to become detectives． To test their skills in recognizing a suspect, he shows the first blonde a picture for5 seconds and then hides it．

“This is your suspect, how would you recognize him?"

The first blonde answers, "That's easy, we'll catch him fast because he only has one eye!" The policeman says, "Well．．．uh．．．that's because the picture shows his profile．"

Slightly confused by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, "This is your suspect, how would you recognize him?"

The second blonde giggles, flips her hair and says, "Ha! He'd be too easy to catch because he only has one ear!"

The policeman angrily responds, "What's the matter with you two? Of course only one eye and one ear are SHOWING because it's a picture of his profile!! Is that the best answer you can come up with?"

Extremely frustrated at this point, he shows the picture to the third blonde and in a very testy voice asks "This is your suspect, how would you recognize him?" He quickly adds, "Think hard before giving me a stupid answer．"

The blonde looks at the picture intently for a moment and says, "Hmmmm…the suspect wears contact lenses．"

The policeman is surprised and speechless because he really doesn't know himself if the suspect wears contacts or not． "Well, that's an interesting answer．．．wait here for a few minutes while I check his file and I’ll get back to you on that．" He leaves the room and goes to his ．office, checks the suspect's file in his computer, and comes back with a beaming smile on his face． "Wow!  I can't believe it．．．it's TRUE! The suspect does in fact wear contact lenses． Good work! How were you able to make such an acute observation?"

"That's easy," the blonde replied． "He can't wear regular glasses because he only has one eye and one ear．"
