Cloning plants is straightforward while cloning animals is a difficult task to undertake. From time to time people suggest that extinct animals should be brought back to life through cloning. Last Friday, we had a discussion about whether we should clone animals.Some are in favour of it. Large quantities of commercial food can be produced. Besides, the extinct animals can be cloned, if their DNA is still in good condition. It can also be used to cure serious illnesses.Others have a strong objection to it.

Above all, it is bound to disturb the balance of nature.◆　高频单词1.differ (vi.) 不同；相异→difference (n.) 不同；差异→different (adj.) 不同的2.exact (adj.) 精确的；准确的→exactly (adv.) 精确地；准确地3.undertake (vt.) 着手；从事；承担→undertook (过去式)→undertaken (过去分词)→undertaking (n.) 任务；项目；事业4.cast (vt.) 扔；投；掷→cast (过去式/过去分词)5.altogether (adv.) 总共；完全地6.object (vi.) 反对；不赞成→objection (n.) 不赞成；反对；异议7.obtain (vt.) 获得；赢得→obtainable (adj.) 可获得的；可得到的8.moral (adj.) 道德(上)的；伦理的→morally (adv.) 道德上地；伦理上地9.accumulate (vt. vi.) 积累；聚积→accumulation (n.) 积累；聚积10.shortly
