unable
to”表达否定意思比较自然一点.而“be able to”就专门用于肯定意思好了.
able
to点用?
答:
be able to=can=have the ability to do something=有能力去做一些事情 have been able to 和 will be able to 只不过是不同的tense have been able to = 现在完成式的"be able to" will been able to=错的,应该是will be able to ,是future tense

答:
It's
unable
for sb to do(do sth)是正确的句型,属于形式主语句。to do/do sth是真正的主语,it是形式主语。对某人来说,做什么是不可能做到的。
第三题她们说选c可是be able to的否定形式不是be

to 作为情态动词否定在be后,文中出现了上学期所以用过去时,答案选C
问下be not able to/be
unable
to/can't 有什么区别
答:
be
able
to 强调某种能力,而can只有“道义”上是否能够去做的意义。i am not able to touch it我没有能力去碰它【是够不着,还是另有隐情?】i cannot touch it我不能碰它【似乎是有人规定“我”】
