在阅读中不理解的:
1.now engineers have a little more than another decade to finish the job.
首先 decade不加s?这里材料中的解释是 工程师们还有十几年的时间来完成
如果decade加上s 指的就不是十几年?
2.Lavitrano said that five to seven other pig genes will need to be silenced or replaced by human genes before useful organs could be harvested from the animal.
材料中答案(与这句意思接近的):human genes will need to take the place of about another six swine genes.
我怎么觉得一看到 six就觉得这个答案不能选呢?它不是说five to seven么?
decade加上s 是几十年不是十几年.因为decade是十年.
five to seven =five or six or seven
