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.
