試題分析：考查動(dòng)名詞用法和情態(tài)動(dòng)詞用法。本題是一個(gè)強(qiáng)調(diào)句型，強(qiáng)調(diào)的是主語playing computer games。該動(dòng)名詞短語在句中做主語。第二空should have done本應(yīng)該做某事實(shí)際上卻沒有做；句意：正是打電腦游戲花去了這個(gè)年輕人很多本應(yīng)該用在學(xué)習(xí)上的寶貴時(shí)間。故D正確。
點(diǎn)評(píng)：強(qiáng)調(diào)句型的最大特點(diǎn)是把it is/was…that/who…去掉，句子仍然成立。本題強(qiáng)調(diào)的是動(dòng)名詞短語做的主語。動(dòng)名詞做主語，表示經(jīng)常性，習(xí)慣性的行為。
