1. this much = so much
this much 是口语的用法，正式的用法是 so much，
Do you always bring this much money with you？
I can only tell you this much.
France did not have the military resources to control this much territory and still protect itself and maintain order at home.
2. able 的比较级
able 的比较级有三个，意思稍有不同
(1) abler 更能干
(2) more able 更能够
(3) better able 更能够, 和 more able 大致相同。
He is an abler actor than I thought. 比我预想的更有才能。
Mary is more able to help you than I am. 玛丽比我更能帮助你
She is better able to speak French than you are，because she was born and bred in France
不要混用，如不能说 more abler,
同样，最高级也有相应的三个，ablest / most able / best able
简友 MarvinTau 介绍一个练习听力的方法，应该有效，分享在这里：
看美剧时，不论谁讲一句话，都暂停下来把那句话重复一遍，语音语调尽可能模仿。虽然这样看一集会很吃力，但是坚持一个月会有奇效。
这个方法应该适用于所有听力练习，不限于美剧。
