I found a treefrog in my studio some months ago .I took it to my greenhouse , as I thought itwould be a better place for the frog .But it came back and insisted taking theresidence in the studio .why? I couldn`t get an idea. Then, after five monthsof being together, we seemed to be able to communicate with each other. It maysound weired, but I did feel I came to understand what it wanted me to do. Thefrog came to me probably attracted by the humming tone of my computer, whichsounded like that of other tree frogs. Or with a message to tell me that frogswere dying around the word because of their sensitivity to the pollution andglobal climate change .As frogs are an indicator species , what has happened tothem may happen to us, if we sit back and nothing .We must act now, or it wouldbe too late.

It seems the young Albert Einstein was never exactly an ordinary child. When he was given a compass at the age of five , it ignited his inspiration. Not only was the young Albert passionately curious, he was also remarkably persistent and would not easily give up on a problem. Albert`s development was also stimulated by the company of intelligent adults such as an uncle of his who was an engineer and a medical student who was a friend of the family. Einstein was inspired to take up mathematics by Euclidean geometry. His true genius lay in his ability to express complex ideas in simple language. By the age of twenty-six Einstein had already produced his most famous work, although he never stopped looking for answers.

The example of Proctor and Gamble's famous Ivory Soap shows the potential that lies in mass marketing and planned advertising and the importance of recognizable brand names.Ivory Soap,first produced in 1879,was well promoted with clever slogans.These slogans,particularly the idea that the soap is so pure that it floats,proved so successful that they are still popular today. At the same time,the use of the radio serial for Ivory promotion gave rise to the expression "Soap opera",which has become a modern giobal phenomenon.The development of Proctor and Gamble itself, from a small-scale operation founded by two immigrants to a multinational empire of today serves as a good example to build brand names.

The Italian doctor Severino Antinori has announced plans to offer human cloning facilities in his private fertility clinics. Antinori is already famous for previous controversies such as helping grandmothers to have babies. Yet this time he is not alone in promoting the idea of human cloning. US scientists are working with him on this project, and a religious group -- the Raelians -- have also announced their intention to offer the service. Of course, with so many couples desperate for a child yet unable to conceive through traditional IVF treatments, there is no shortage of volunteers. It would probably not work trying to prevent cloning, thus some form of regulation is almost inevitable. At the moment, cloning techniques are far from perfert and most attempts to clone animals end up in failure.

This is an amusing short story which illustrates how little people know about their mother tongue sometimes.The narrator is a woman,a passenger in a taxi whose driver is a Pakistani man eager to learn English by asking his passengers about new words.Struggling to explain the meanings of a proverb and an idiom,she realizes how little she really knows about the vocabulary of her native language and also wonders what kind of answers other,probably equally ignorant,native passengers might give.In the end she is left hoping that the driver has a dictionary and that he will use it to teach himself rather than depend on the native speakers for explanations.
