Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my daughter‘s experience. (07.12 Passage 2)
分析主干：I had to accept the fact...
Because 引导原因状语从句。该从句用了know little about...结构，about 有两个宾语。that 引导的从句是即farm animals 和angels，中间用or 连接，两个名词分别都有定语从句加以修饰。主句部分fact 带有that 引导的同位语从句。
译文：因为我对会使用工具的家畜和上一年级的天使一无所知，所以我得承认这样的事实：我在借用我女儿的经验。
The I SO 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)
分析主干院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。
