[解析]
(1)A.细节理解题。根据第二段"The company has already successfully cloned at least 400 dogs,mostly for US customers,ever since it pioneered the technique in 2005. (自2005年率先采用这项技术以来,该公司已经成功克隆了至少400只狗,大部分是为美国客户克隆的。)"可知,这个组织提供克隆狗的服务。故选A项。
(2)D.细节理解题。根据第三段"To clone a dog,researchers first need to take a skin cell from a living dog or one that has just died.Meanwhile,another dog is selected to supply an egg.Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog.The egg grows into a puppy over the following two months.(为了克隆一只狗,研究人员首先需要从活着的狗或刚死去的狗身上提取皮肤细胞。与此同时,另一只狗被选中提供卵子。然后,研究人员用皮肤细胞中的DNA替换卵子中的DNA ,并将卵子植入母狗的子言中。卵子在接下来的两个月里长成一只小狗。)"可知,克隆狗的过程为: (1)从狗身上提取皮肤细胞; (2)选择另一只狗来提供卵子; (3)用皮肤细胞中的DNA替换卵细胞中的DNA; (4)在一只母狗的子言内放入卵细胞; (5)两个月后卵子发育为一只小狗。因此正确顺序为:baedc。故选D项。
(3)C.推理判断题。根据第四段"However,magical as cloning might sound,there is no guarantee that the dloned dog will be a perfect copy of the original one.(然而,尽管克隆听起来很神奇,但并不能保证这只克隆狗会是原来那只的完美复制品。)"中的no guarantee可知,克隆狗可能不会让主人得到完全一样的狗。故选C项。
(4)A.推理判断题。根据最后一段"Perhaps bringing our dogs back by cloning is not the best way to remember them after all.Kirkwood,a dog owner himself,pointed out, "An important aspect of our relationship with them is coming to terms with the pain of letting go."(也许通过克隆把我们的狗带回来毕境不是记住它们的最好方式。Kirkwood自 己也是一名狗主人 ,他指出:"我们与狗狗之间关系的一个重要方面就是要接受放手的痛苦。" )中的letting go可知,Kirkwood认为,在人与宠物之间的关系中最重要的一方面就是处理好它们离去所带来的痛苦。由此可推测,Kirkwood是反对克隆狗的。故选A项。
