Have you ever imagined that you could be cloned(克隆)like Dolly，the sheep，in the not too distant future? The news that a human embryo(胚胎)has been 36 cloned for the first time has caused mixed reactions(反应)． The 37 was carried out by scientists from the Advanced Cell Technology Inc(ACT)，in Massachusetts，US. The group 38 the news on November 25. This is not a cloned human being. “A 39 is alive，it walks，it breathes，”said Jamie Grifo，an expert on the study of cloning at New York University School of Medicine. “This is a set of cells in a lab that will be used to 40 someone's life.” Such research could lead to treatment for 41 such as heart disease，AIDS and even cancer， 42 scientists. Despite high hopes from other scientists，the news 43 concerns immediately from religious and political leaders. Several 44 in the US do not allow human cloning. President George W ．Bush also made it clear that he is 45 any type of human cloning. However，the 46 at ACT said they have no interest at present in developing an early embryo into 47 . Animals have been cloned repeatedly since Dolly，the sheep, 48  in 1997.And there were no real technical  49 to stand in the way of scientists making a cloned human embryo. This time the research group used traditional cloning technology with a human 50 . 51 it was given DNA from an adult cell，the egg began to 52 . 53 it was stopped from becoming a baby—at a stage in which it was 54  a ball of cells. The  55 technology has been used to clone sheep，cattle and monkeys. 小题1: A．in failure B．never C．successfully D．not 小题2: A．research B．report C．works D．task 小题3: A．made known B．made C．said D．had 小题4: A．cell B．person C．man D．clone (克隆人) 小题5: A．save B．kill C．cure D．treat 小题6: A．patients B．health C．diseases D．things 小题7: A．according to B．including C．besides D．argued 小题8: A．beat B．lost C．raised D．missed 小题9: A．countries B．nations C．peoples D．states 小题10: A．for B．against C．researching for D．praising 小题11: A．scientists B．president C．people D．research 小题12: A．a baby B．a man C．a woman D．a white man 小题13: A．lived B．appeared C．turned D．was no more 小题14: A．questions B．affairs C．business D．problems 小题15: A．egg B．bless C．meat D．cell 小题16: A．Before B．After C．While D．And 小题17: A．grow B．die C．change D．appear 小题18: A．And B．But C．However D．Yet 小题19: A．yet B．still C．not D．/ 小题20: A．different B．usual C．ordinary D．same
