A The history of cloning animals is as fol?lows. Cloning of nonmammals was first ac?complished in 1952. However,cloning of mam?mals proved much more difficult,with the first successful clone being the sheep,Dolly,in 1996. Dolly died a young death,probably due to the use of aged chromosomes (染色體) in her nuclear transfer (核移植) .Other mammal spe?cies followed rapidly,with mice and cows being cloned in 1998,and pigs in 2000. The first cat was cloned in 2001. Rabbits were cloned in 2002 and the first male mammal (a mule) was cloned in 2003. In 2004,a bull was cloned from a previously cloned bull. The first cloned human embryos were not produced until 2001,when a private company Ad?vanced Cell Technology produced 6-cell embryos. Howev?er,the first cloned human blastocyst (胚泡) was not pro?duced until 2004 by a group in Korea.
Cloning is classified as research and reproductive (繁殖的) cloning. When the embryo is not allowed to live,it is considered research cloning. Otherwise,it is classified as reproductive cloning. About ten states have banned repro?ductive cloning with five banning research cloning. Puerto Rico proposed a worldwide ban of reproductive and re?search cloning in 2003 through the UN. However,objec?tions by Great Britain and other countries resulted in the proposal being formally presented until 2004.
From a Christian theistic (有神論的) world view,cloning or deliberately making changes in the human blue?print is playing God. This is something that would not be forgiven. Alternatively,from the opposite humanist world view,human engineering is no more than helping evolu?tion. Our position on this issue,like so many other cultural issues,is dependent upon our belief on a more fundamental world view truth. This can be seen in the conflicting views regarding government funding and support or alternatively restrictions and moratoriums (暫停,中止) .
11. When was the first male mammal cloned?
A. In 1952. B. In 1996.
C. In 1998. D. In 2003.
12. Which of the following is the correct time order of the animals cloned?

14. Which of the following was probably in favour of clo?ning according to the passage?
A. Great Britain. B. The UN.
C. The United States. D. Puerto Rico.
11. D細節(jié)理解題。根據(jù)第一段"…and the first male mammal: (a mule) was cloned in 2003."可知,第一個雄性哺乳動物于2003年被成功克隆。
12. C推理判斷題。根據(jù)第一段可知,克隆Dolly的時間為; 1996年,cow為1998年,pig為2000年,cat為2001年,bull為2004年,因此C項的排列順序正確。
13. A細節(jié)理解題。根據(jù)第二段第二、三句可知,不允許胚胎存活的為"研究性克隆",否則為"生殖性克隆"。
14. A推理判斷題。根據(jù)第二段最后兩句可知,Puerto Rico I 于2003年向聯(lián)合國提出禁止生殖性和研究性克隆的研究,但是由于Great Britain及其他一些國家的反對,這項提議.”:被擱置到2004年。由此推斷,Great Britain極有可能支持i 克隆。

Last weekend we went mountainclimbing. Even the heavy rain can not stop us. We set off early and went along an extreme narrow road,all in high spirit. On either side of the road was green fields. We could hear the sound of the rain mixing with our laughter. At noon we reached to the top of the mountain,there we were amazed by the beauty of the scenes. After short rest,we started going down. It rained more harder. We were wet all over,and we still felt happy.
