10，E，they前面有2个pl。指代模糊。牵强吧，实在找不到别的错了。

12，D，当specially有especially的意思时，specially只在口语中用。GMAT不考口语。to deal 可能会修饰system。这是A为什么不用of结构的原因。

ETS很狡猾。专门考我们容易错的地方。请NN发表高见。

同意解释

谢谢！

能再解释一下这句话?

1.ablity to do 是习惯用法,对吗? to deal 可能会修饰system?

2.system 's ablity不是说只有人的所有格时候才用'S吗?这里为什么可以用?

我觉得第一题的d和e主要是句子重心的差别，句子主要强调结果，而不是原因，所以d对

代词指带的错误有点牵强

2.system 's ablity不是说只有人的所有格时候才用'S吗?这里为什么可以用?

这条公理我认为可以不记，gmat中非人的所有格用'S的不少。

睡了一晚上。想出点ETS的思路供大家来批。

I do not think A, because B...     ETS要我们翻译成认为A不是因为B；即逻辑中的A->~B, 是个逆否命题，强调结论。　

上句话也可以是：B->~A就是原命题的逻辑；

所以当原因状语主从句表达否定意思时，because在后是逆否命题，强调结果。because在前是原命题，强调原因。

但是表示肯定意思时，就不大清楚了。因为英语和中文的意思是一样的。

请指教？？？

不愧为逻辑区的版主。我感觉这么说是有些道理，不过最好还有更多的例子来说明佐证，否则还是有点抽象。

这题我没想到这么深，选的依据主要是选最常见的，最不可能产生歧义的选项。就如doing sth. ，sb+谓语和sb.，doing sth，谓语，如果其它看不出什么不同，只是doing的位置不同，我就选前者，因为这最常用，最不容易错。

I do not think A, because B 的意思只有：因为B，所以不认为A（I don't think A and the reason is B)

I do not think A because B的意思可能是：因为B，所以不认为A (I don't think A and the reason is B)or 不是因为B才认为A(I think A and the reason is not B)，一般取后者。

逗号很关键,没有逗号会引起歧义，书面语中一般取后者，口语中根据重音决定。

这点我同意！！

weiyu考虑的好仔细！

不过，ets应该不会考的这么细吧~~
