       Now scientists say that they can change the genetic makeup of certain animals so that their organs may be        humans. With this gene-altering technique to overcome our immune rejection to foreign organs, scientists hope to use pig hearts for transplants by the year 2010.

       Animal-rights activists say the whole idea of using animal organs is cruel and unjust. "Animals don't exist as tools for human beings, or for replacement parts," they protest. Some scientists also worry about unforeseen consequences of this technique. They fear such transplants may transmit unknown disease to humans.

       Others believe transplanting animal organs into humans is unnecessary. The millions of dollars spent on breeding cows and pigs for their organs could be better spent on health education  programs. Seventy-five per cent of the heart and liver disease cases that lead to a need for organ transplant are preventable, they say. The key is to convince people to have a healthy diet, and not to smoke or drink alcohol. Scientists could also use research funds to improve artificial organs.

       Still others believe that though new inventions and prevention programs may help, spending money to encourage more people to donate their organs is an even better idea. "Each year we lose 50,000 to 80,000 organs because doctors don't tell us about deaths, or because families say no," says Swasey, who had a heart transplant seven years ago. "If we educated enough people about organ donations, we could take everyone who needed an organ off the waiting list in a year."

How does it happen that children learn their mother tongue SO well?When we compare them

With adults learning a foreign language，we often find this interesting fact．A little child without

knowledge or experience often succeeds in a complete mastery of the language．A grown—up person with fully developed mental powers，in most cases，may end up with a faulty and inexact corflllland．What accounts for tllis difference?

Despite other explanations。tlle real answer in my opinion hes partly in the child himself，partly in the  behaviour of the people around him．In the first place，the time of learning the mother tongue  in the most favorable of all，namely，the first years of hfe．A child hears it spoken from morning till night and，what is more important，always in its genuine form，with the right pronunciation，rightIntonation，right use of words and right structure．He drinksin all the words and expressions which come  to him in a hsh．ever—bubbhng spring．There is no resistance：there is perfect assimilation．

Then the child has，as it were，private lessons all the year round，while an adult language—

student has each week a limited number of hours which he generally shares with others．The child

has another advantage：he hears the language in all possible situations，always accompanied by the

right kind of gestures and facial expressions．Here there is nothing unnatural，such as is often found

In  language lessons in schools，when one talks about ice and snow in June or scorching heat in January  And what a child hears is generally what immediately interests him．Again and again，when his attempts at speech a聪successful，his desires are understood and fulfilled．

Finally，though a child’S“teachers”may not have been trained in language teaching，their re-

lations with him are always close and personal．ney take great pains to Inske their lessons easy．
