2019-2020年高中英語 Unit 3 Science and nature教案 牛津譯林版必修5 【美文閱讀】　 克隆動物早已不再“猶抱琵琶半遮面”。為了保護克隆的福利，歐盟委員會這次走得更遠…… EC approves the sale of cloned young into the food chain The European mission has published a report approving the right of member states to sell cloned animals young and their products into the food chain. The mission said a ban would not be proper in terms of protecting animal welfare and public health.It added that a clone traceability(可追蹤)system would be needed，because food from the clones young “cannot be distinguished from food from other animals”． The move could cause a big change from the UK Food Standards Agency(FSA) which at present forbids the sale of food from the clones young without a license—farmer Steven Innes was found to have done so last year and should be punished.Under the missions proposal，Mr.Innes would not be punished.Indeed all farmers in the UK would be able to buy materials from clones from outside the European Union and sell their products into the food chain. George Lyon，Liberal Democrat MEP for Scotland，said，“Its clear that the FSA is out of line with the rest of member states in how it explains the present rules and，of course，under these new rules，it still is out of line.So hopefully they will e to their senses and see they do have to move on this subject.” 【誘思導學】 1．Whats the passage mainly about? ________________________________________________________________________ 2．Why is a ban on selling cloned animals not suitable for the present situation? ________________________________________________________________________ 【答案】　1.The sale of cloned young has been made legal by EC.或：The EC approves the sale of cloned young into the food chain. 2．Considering cloned animals have appeared，there is a possibility that people sell them and get food from them.If there is a ban，some people may sell them illegally and then its likely to prevent animal welfare and public health from protection.
