【正文】 eadi ng us to the hunt agai n. Usi ng a tel escope we coul d see that som ethi ng was happeni ng. As we drew cl oser, I coul d see a whal e being attacked by a pack of about si x other kil l ers. “What’re they doi ng?” I asked Gee. “Wel l, it’s team work the kil l ers over there are throwing them sel ves on top of the whal e’s bl owhol e to stop i t breathi ng. And those others are stoppi ng i t di vi ng or fl eei ng out to sea,” Gee tol d m e, poi nting towards the hunt. And just at that m om ent, the m ost extraordi nary thi ng hapened. The kil l ers started raci ng between our boat and the shal e just li ke a pack of exci ted dogs. Then the harpoon was ready and the m an i n the bow of the boat ai m ed i t at the whal e. H e l et i t go and the harpoon hi t the spot. Bei ng badl y wounded, the whal e soon di ed. Wi thi n a m om ent or two, its body was dragged swi ftl y by the ki l ers down i nto the depths of the sea. The m en started turni ng the boat around to go hom e. “What’s happened?” I asked. “H ave we l ost the whal e?” “O h no, ” Jack repli ed. “We’l l return tom orrow to bri ng i n the body. It won’t fl oat up to the surface for around 24 hours.” “ In the m eanti m e, Ol d Tom, and the others are havi ng a good feed on i ts li ps and tongue, ” added Red, laughing. ● ● ● Al though O l d Tom and the other ki l ers were fierce hunters, they never harmed or attacked peopl e. In fact, they protected them . There was one day when we were out in the bay duri ng a hunt and James was washed off the boat. “ Man overboard! Turn the boat around!” urged Gee, shouting l oudly. The sea was rough that day and it was diffi cul t to handle the boat. The waves were carryi ng James further and further away from us. From James’s face, I coul d see he was teri fied of being abandoned by us. Then suddenly I saw a shark. “Look, there’s a shark out there,” I screamed. “Don’t worry, O ld Tom won’t let it near, “Red replied. It took over hal f an hour to get the boat back to James, and when we approached hi m, I saw James being firml y held up in the water by O ld Tom. I couldn’t beli eve my eyes. There were shouts of “Wel l done, O ld Tom” and “Thank God” as we pul ed James back i nto the boat. And then Ol d Tom was off and back to the hunt where the other ki l ers were stil attacki ng the whal e. A NEW DIMENSION OF LIFE 19th January I’m sitti ng i n the warm ni ght ai r wi th a col d dri nk i n m y hand and refl ecti ng on the daya day of pure m agi c! I went snorkel ing on the reef offshore thi s m orni ng and i t was the m ost fantasti c thi ng I have ever done. Seei ng such extraordinary beauty, I thi nk every cel i n m y body woke up. It was l i ke di scoveri ng a whol e new di mensi on of li fe. The first thing I be e aware of was al the vi vi d col ors surroundi ng m epurpl es, reds, oranges, yel ows, bl ues and greens. The coral s were fantasti cthey were shaped li ke fans, pl ates, brai ns. Lace, m ushrom s, the branches of trees and the horns of deer. And al ki nds of sm al l, neat and el egant fi sh were swim mi ng i n and around the coral s. The fi sh di dn’t sem to mi nd m e swimm i ng am ong them . I especi al y l oved the li ttl e orange and whi te fish that hi d i n the wavi ng long thi n seaweed. And I al so loved the sm al l fish that cl ean the bodies of l arger fishI even saw them get i nsi de thei r m ouths and clean thei r teeth! It seem ed there was a surpri se waiti ng for m e around every corner as I expl ored sm al l caves, shelves and narrow passages with m y underwater fl ashl i ght: the yel ow and green parrotfi sh was hangi ng upsi de down, and sucki ng ti ny plants off the coral wi th i ts hard bi rdli ke m outh。on 6April , 1992, when he di ed as a result of an H IV i nfecti on that he had got from a bl ood transfusi on ni ne years earli er. When Asi mov was three, he m oved with hi s parents and hi s oneyearol d si ster to N ew York City. There hi s parents bought a candy store whi ch they ran for the next 40 or so years. At the age of ni ne, when hi s m other was pregnant wi th her thi rd chi l d, Asi mov started worki ng parttim e i n the store. H e hel ped out through hi s schol and uni versity years unti l 1942, a year after he had gai ned a master’s degree in chemi stry.

The next year he becam e a bi ochem istry teacher a Boston Uni versi ty School of Medi ci ne. In 1958 he gave up teachi ng to be e a ful lti m e writer. It was when Asi mov was el even years ol d that hi s tal ent for wri ti ng becam e obvi ous. H e had tol d a fri end two chapters of a story he had wri tten. The fri end thought he was reteli ng a story from a book. Thi s real y surpri sed Asim ov and from that m om ent, he started to take him sel f seri ousl y as a wri ter. Asim ov began havi ng stori es publi shed i n sci ence ficti on m agazi nes i n 1939. In 1950 he publi shed hi s first novel and i n 1953 his fi rst sci ence book.

It was l oosel y based on the fal of the Rom an Em pi re but was about the future. These books are fam ous because Asim ov i nvented a theoretical fram ework whi ch was desi gned to show how i deas and thi nking m ay devel op i n the future.
