问题补充：
单选题Themicrophoneenabledthemtokeepintouch,inotherwords,itmadeit_____forthemtocontacteachother.A.likelyB.capableC.possibleD.probable
答案：
C解析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.
