2．Textbooks for junior students ______ for free in most areas of China．（　�。�
A．provideB．providedC．are provided

分析 在中國大部分地區(qū)都免費提供初中學生的課本．

解答 答案：C
聯(lián)系語境，根據(jù)本句的主語為textbooks，結(jié)合選項謂語動詞為provide，可知主語為謂語的動作承受者，指課本被提供，所以應(yīng)該用被動語態(tài)；結(jié)合句意可知本句描述的為客觀事實，所以應(yīng)該用一般現(xiàn)在時，故此句應(yīng)該用一般現(xiàn)在時的被動語態(tài)來表達，其構(gòu)成為：am/is/are+過去分詞；本句的主語textbooks為復數(shù)，所以用are，provide的過去分詞為provided，故選：C

點評 本題考查一般現(xiàn)在時的被動語態(tài)．首先根據(jù)主謂語的關(guān)系確定出被動語態(tài)；再結(jié)合句子的意義確定出正確的時態(tài)；最后套用相關(guān)時態(tài)的被動語態(tài)的構(gòu)成即可得出正確答案．
