Rice _____(grow) in many Asian and some European countries. 2. Yuan Longping _____(bring up) in China. 3. The new hybrid rice _____(develop) by the Yuan Longping High-tech Agricultural Company of China. is grownwas brought uphas been developed 3. 被动语态的特殊结构形式。 (1) 带情态动词的被动结构。其形式为：情态动词＋be＋过去分词。 *The question needn’t be discussed. 这个问题不必讨论。 *The classroom must be cleaned at once. 这个教室必须立即打扫。 (2) 有些动词可以有两个宾语，在用于被动结构时，主动结构中的间接宾语变为主语时，直接宾语仍然保留在谓语后面；直接宾语变为主语时，间接宾语前通常加上介词for/to。 *He was asked a number of questions at the press conference. 在记者招待会上人们问了他很多问题。 *A new MP4 was given to him as a birthday present/gift. 他收到了一个新MP4作为生日礼物。 二、难点突破 在下列情况中，谓语形式是主动的，但具有被动的含义。 (1)“系动词look, sound, feel, taste, smell, prove, appear+形容词”构成的系表结构，主动形式表示被动意义。 *The food tastes delicious. 这种食物尝起来很可口。 *The idea sounds good. 这个主意听起来不错。 (3)动词want, need, require, deserve后接动名词的主动形式表示被动意思，这时动名词和句中的主语存在逻辑上的动宾关系。 *The room needs cleaning. = The room needs to be cleaned. 这间房屋需要打扫。 (4)be worth doing sth. 动名词和句中的主语存在逻辑上的动宾关系。 *The film is well worth seeing. 这部电影很值得一看。【高考体验】 掌握被动语态的答题技巧: 1. 判断主语与谓语之间的逻辑关系。 2. 注意动词是及物的，还是不及物的。 3. 要熟记没有被动语态形式的常见的动词。1.
