"Time is a problem for children," states a news report for a new Swiss watch. Children in some countries" learn time slowly" because" they don’t wear watches" and " parents don’t really know how to teach them time. " The children grow up with this handicap and become adults (成人) —and then can’t get to work on time. Is there an answer to this problem? Of course — it’s the Flik Flak, made by a famous Swiss watch company.

The Flik Flak is being marketed as something teaching watch for children aged 4 to 10. The watch itself does not teach children how to tell time, of course; it merely " takes their imagination" by presenting the " hour" hand as a beautiful red girl named Flak and the " minute" hand as a tall blue boy named Flik. Flik points to related" blue" minutes on the dial, while Flak points to " red" hour numbers. The characters and colors combined with parental help, are supposed to teach young children how to tell time.

The watch comes equipped with a standard battery (电池) and a nylon band (尼龙表带). Peter Lipkin, the United States sales manager for the Flik Flak, calls it " childproof if it gets dirty you can throw the whole watch in the washing ma­chine. " The product is being sold in select department stores in Europe, Asia and the United States for a suggested price of $25. Parents who buy the watch may discover that it is one thing to tell time; it’s quite another for them to be on time.

D. children usually have trouble telling time if they don’t wear watches

3. The underlined word handicap in Para. 1 means

A. displeasure        B. discouragement        C. disappointment     D. disadvantage

4. The United State sales manager calls the new watch " childproof" because ______.
