关于able的用法 辅导书上说able接不定式时,只能接肯定的、主动的不定式,不能接被动的不定式.需要时可由can代替：His voice was not able to be heard.（误)His voice couldn't be heard.（正）但朗文字典上给出的例句：I'd like to do more gardening ,but I never seem able to find the time.I haven't been able to read that report yet.这不是出现否定了吗?到底应如何理解【只能接肯定的、主动的不定式】ps：不要和我说辅导书错了,那本还是比较权威的.

首先,只能接主动的不定式,不能接被动的不定式,这一点,你所指出的朗文字典上给出的例句并没有违反； 其次,只能接肯定不定式,这是说,不能出现be able not to do,但是可以说not be able to.那be notable to. 可以吗 His voice was not able to be heard对不对可以用be notable to.His voice was not able to be heard不对，able一般表一种能力。
