D．probable

Answer 1

B

able有才能的，有能力的，指人的才智，而且是受过实际锻炼的才干。Capable“有才能的，能胜任的”(有褒、贬二义)，如：He is capable of anything.(他什么事都干得出来。)此句含有明显得贬义。此外，作表语时，able接不定式，capable接of. capable还有一意思是“有可能的”，例如：The car is capable of being repaired .（这辆汽车是有可能修好的。）用于此义时，be capable of 后常接被动语态动名词或有动作意义的名词：The situation is capable of improvement .possible 强调客观可能性，“可能的”程度比probable"大概的，很可能的低一些。
注意likely与possible在结构搭配上的区别。Likely可用于下列句型中：1)It is likely that...例如：It is highly likely that he will succeed.（很可能他会成功。）2)think(feel, consider)it likely ...例如：I think it likely that we will ultimately get a certain amount of money.3)be likely to do sth.例如：He is likely to see you again .但下面的句型是错误的，It is likely for sb to do sth.所以think it likely for sb. to do sth.也是错误的，故本题不能选likely.
