The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as “environmentally friendly”and “non-polluting”cannot be verified. (05.6 Passage 2)
分析主干The standards ban claims本句只含一个原因状语从句,结构上较为简单。值得注意的是,句中的名词词组大多含有修饰成分,如:The ISO labeling standards, claims on product packaging, terms such as...。
译文ISO 标识标准禁止在商品的包装上出现模糊的或会引起误导的产品说明,因为我们无法证明类似“环保”、“无污染”等这样的字样。
While the kinds of instruction offered in these programs will differ, distance learning usually signifies a course in which the instructors post syllabi (课程大纲), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. (07.12 Passage 1)
分析主干:distance learning signifies a course
1.句首While 引导状语从句,有让步、对比之意。
2.in which 引导定语从句修饰a course,该从句本身是and 连接两个分句构成的并列结构,两个分句分别讲到有关老师和学生的情况。post... on Websites 结构中,post 含有3 个宾语。
译文:虽然网络课程提供的教学形式会各不相同,但远程学习通常都表现为这样一种课程:教师将课程大纲、阅读作业及课程进度安排在网站上公布,学生通过电子邮件提交作业。
Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most distance learning courses can run on existing or minimally upgraded ( 升级) systems. (07.12 Passage 1)
分析主干:courses can run (on...)
Although 引导让步状语从句。investment in...表示“在......方面的投资”。不定式to support... 是宾语investment 的补足语,“项目需要投资来支持相关软件”(因为)support 的逻辑主语不是programs 而是investment,所以该不定式应该是补语,而非目的状语)。
译文:虽然一些规模更大的课程需要斥资增加新的服务器、扩建网络来支持配套的软件,但大部分远程教育课程可以在现有的或稍加升级的系统上运行。
