　　參考答案&解析：

　　1、C　able有才能的，有能力的，指人的才智，而且是受過實際鍛煉的才干。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 強調(diào)客觀可能性，“可能的”程度比probable"大概的，很可能的低一些。

　　2、B　worthwhile值花時間(或精力)干的：1)The visit to Paris was worthwhile .2)He thinks teaching foreign languages is worthwhile.3)She has a very worthwhile job.4)I think it worthwhile to work on my stamp collection.

　　Worthy (of)配得上，值得：1)He is worthy of being praised.(=He is worthy to be praised.)2)He is a worthy winner.3)She is not worthy to talk to man like you.(她配不上與你這樣一位男士談話)。

　　3、B　soundly　sleep soundly熟睡。也可以說sleep heavily.

　　4、D　pick up學(xué)到，習(xí)得。

　　5、C. bound　be bound to sth.受...的約束：I was bound to my promise.(我受我的諾言約束)[注意]be bound to do sth.1)一定會：The plan is bound to win.(這項計劃一定會成功。)2)有責(zé)任(義務(wù))：You are bound to obey the laws.(你有責(zé)任遵守法紀(jì))。
