The truth about cloning cats and dogs When I first read about the controversial topic of pet cloning, I was shocked by the topic that was published on the Internet. Such services would have consumers who believe that to clone their pet is to extend time with a beloved friend. These merchants mislead pet lovers. Also important to consider is the influence of environment and experience on personality.,Thus, it is not sure that pet cloning will result in an animal that has the same appearance or personality as the original animal. “Clone your pet” companies claim that the cloning process increases scientific knowledge of animal. What they fail to mention is the research involved in pet cloning. It is done purely to further the purpose of reproduction through the cloning process, and not to find cures to diseases and genetic abnormalities(畸形). It does not benefit animals or humans. In fact, as pet cloning is done for only commercial purposes, it exploits(利用 ) animals. ①Research_involved_in_pet_cloning_is_not_publicly_regulated,_so_it_is_unknown_whether_advances_made_are_beneficial_to_any_scientific,_non-commercial_community.,Considering the millions of homeless cats and dogs each year, it is irresponsible(不負(fù)責(zé)的) of “clone your pet” companies to create more through cloning. The money that will be spent to create one animal would go a long way to help thousands of homeless dogs and cats to provide shelter. ②When_it_comes_to_cloning_animals_for_commercial_purposes,_the_only_benefit_is_the_money_made_by_cloning_companies. Consumers wrongly believe that a loved one will be brought back to life, while millions of dogs and cats that have already been born naturally wait in shelters to be adopted. I hope that customers will do their own research on the topic, rather than falling for clever marketing.,1．佳句仿寫 ①在這么短的時(shí)間內(nèi)她不可能完成這項(xiàng)工作。(it is ＋adj.＋主語從句) _________________________________________________________ ②說到德語，我什么都不懂！(when it comes to.) _____________________________________________,When it comes to German, I know nothing.,2．翻譯佳句 放眼高考 What they fail to mention is the research involved in pet cloning. __________________________________________,他們沒有提到的是有關(guān)寵物克隆的研究情況。,Ⅰ.單詞識(shí)記 1．________ v．to make someone extremely afraid 2．________ v．to quickly follow someone or something in order to catch them 3．________ v．a(chǎn) strong feeling of dislike, annoyance, or disapproval,terrify chase disgust,4．________ n．a(chǎn) strong human feeling such as love, hate, or anger 5．________ adj.not living, or not having living things on it 6．________ v．unlawful killing of a human being intentionally 7．________ v．say or show that one is unwilling to give, accept, grant or do sth,emotion lifeless murder refuse,Ⅱ.短語天地 1．____________(火)燃盡，燒完自滅 2．______________與……形成對(duì)照 3．____________________撲倒在……上 4．make a sound____________ 5．a(chǎn)gain and again____________,burn out contrast with throw oneself on.,發(fā)出聲音 一再，屢次,Ⅲ.句型搜索 1．Boris Karloff played the monster in the 1931 film Frankenstein，as shown in the picture on this page.
