D．probable

Answer 1

B

able有才能的，有能力的，指人的才智，而且是受過實(shí)際鍛煉的才干。Capable“有才能的，能勝任的”(有褒、貶二義)，如：He is capable of anything.(他什么事都干得出來。)此句含有明顯得貶義。此外，作表語時，able接不定式，capable接of. capable還有一意思是“有可能的”，例如：The car is capable of being repaired .（這輛汽車是有可能修好的。）用于此義時，be capable of 后常接被動語態(tài)動名詞或有動作意義的名詞：The situation is capable of improvement .possible 強(qiáng)調(diào)客觀可能性，“可能的”程度比probable"大概的，很可能的低一些。
注意likely與possible在結(jié)構(gòu)搭配上的區(qū)別。Likely可用于下列句型中：1)It is likely that...例如：It is highly likely that he will succeed.（很可能他會成功。）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 .但下面的句型是錯誤的，It is likely for sb to do sth.所以think it likely for sb. to do sth.也是錯誤的，故本題不能選likely.
