一、主旨 还有个阅读是说语言和biology relationship(待确认) 二、段落大意 P1. conventionalmethod只能trace the origin of language至thousands of years ago,但是a biologist运用新方法能将其追溯至a hundred thousand years ago。这个方法类似DNA序列研究,利用statistics method来分析phoneme(音位,language中最小的单位),从而进行推断。这个biologist发现距离southwestern Africa越远,氏族搬离的离这个地方越远,语言中的pronounce越少,phoneme也就越少,这是生物多样化基因不断重组的结果。进而得出the originof language是在southwestern Africa的结论。/P越小说明语言才开始发展,然后人口迁徙P也会小。先是M开头的一人给提出一个结论,根据statistical method,然后第一段最后一句又有个C开头的人反驳M的观点。然后两个人就collaborate搞在一起干嘛了。
请确认作文: The following appeared as part of a newspaper editorial: “Two years ago Nova High School began to use interactive computer instruction in three academic subjects. The school dropout rate declined immediately, and last year’s graduates have reported some impressive achievements in college. In future budgets the school board should use a greater portion of the available funds to buy more computers, and all schools in the district should adopt interactive computer instruction throughout the curriculum.”
