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 being 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.

(答案→)C
解析：文章讲述了克隆人类细胞的问题以及不同的人的不同反应。
【小题1】形容词辨析。感觉上下文可知人类胚胎已经被成功的克隆出来了。
【小题2】名词辨析。A研究；B报道；C作品；D任务；对人类胚胎进行的肯定是研究。
【小题3】词义辨析。根据上下文可知这里是在11月25号宣布了这一消息。Make known宣布，使…为别人所知；
【小题4】名词辨析。根据上下文可知克隆人并没有被研究出来，只是克隆出人类的胚胎。所以说克隆人是活着的，会走路，会呼吸。而现在克隆出来的只是胚胎。
【小题5】动词辨析。根据上下文可知克隆胚胎可以救人。
【小题6】上下文出来。根据后面的such as heart disease知道这里提及的是疾病。
【小题7】介词辨析。根据句意可知：根据医生的说法。应该使用according to.
【小题8】动词辨析。A击打；B失去；C引起；D错过；句意：这个消息引起了人们的担心。
【小题9】名词辨析。A国家；B国家，种族；C民族；D州；句意可知是美国的几个州禁止克隆。
【小题10】词义辨析。A支持；B反对；C搜寻；D表扬；根据句意可知Bush总统是反对克隆人的。
【小题11】名词辨析。根据上下文可知ACT是一个研究机构，那么应该是科学家。
【小题12】名词辨析。根据常识胚胎应该先成为婴儿。
【小题13】动词辨析。A生活；B出现；C变化。根据句意可知Dolly是在1977年出现的。
【小题14】名词辨析。A问题；B事务；C生意；D难题。根据句意可知：克隆人类胚胎已经没有技术难题了。
【小题15】上下文串联。根据后文的可知是egg。
【小题16】连词辨析。根据上下文可知是在t was given DNA之后。
【小题17】动词辨析。A生长；B死亡；C改变；D出现。根据句意可知是egg开始生长。
【小题18】上下文串联。根据上下文可知这里是转折关系，egg本应该继续长，但是却停止了生长。
【小题19】副词辨析。根据文意可知egg停止生长以后仍然是一个a ball of cells。
【小题20】上下文辨析。根据上下文可知是同样的技术被运用到别的到我身上。
