三道OG上的SAT语法题

In Germany, foresters discovered that trees killed by acid rain had begun to die four years (earlier, even though the trees had shown no signs of disease them)
n.
D earlier without any signs of disease shown then
这个题答案选A，不知道D为什么错。。
test 3, section 6,18
(As) children mature, they develop (an independence) that their parents, who (have been) responsible for them since they were born, often find difficult (to accept). (No error)
为什么用an independence不用independences

Test3 Section10 5
The Poetry Book Society is an organization in London that (provides information and guidance for all lovers of contemporary poetry and giving them discounts on books of poetry.)
C not only provides information and guidance for lovers of contemporary poetry and were giving discounts on books of poetry
B provides information, guidance, and the getting of discounts on books of contemporary poetry
答案是C，可是C里面的they会不会指代不明？按照句子结构的话they应该指information and guidance吧。。。觉得B也挺对的

Answer 1

1. show没有被动 只能说trees show signs 而不能说sign are shown 这样跟你说可能好点，如果你想用D的形式，那也得是without showing any signs of disease 也和逻辑主语有点关系
2.这是单复数下一个比较难的考点。这么记好点：情感上能共享的用单数：have a feeling, a desire, an independence..etc 生理上不能共享的用复数： raise their voices, change their minds, win their hearts
3.其实是个平行 简化一下就是 it is an organization that not only provides something for lovers but also gives them something.平行成分一provide sth for lovers 成分二 gives them discounts them的指代在这里是明确的(借此提醒一下你的C打错了...)
B项 一个 the getting of 直接废了，第一不平行了（若平行直接删了就留discounts) 第二根本没这个用法 这个get是想指让them 得到 折扣，但是没这么用的，读着就奇怪

Answer 2

1 因为没有病变症状和前面的一句话没有太多关系，要用表转承的词（even though)来连接，without虽然意思上没有错，不过不能表转承
2 因为independence这里翻译成独立性，大家都有独立性（是一种东西）所以不能用复数
3 不会指代不明啊，因为就近原则，只可能是说information and guidance，B项不能体现出即提供了information and guidance又提供了discounts on books of poetry，而且provides the getting of discounts on books of contemporary poetry句意也有所改变，不如C好啦
