33. The passive voice 被动语态 语态是表示主语与谓语的关系的。如果主语是动作的执行者，动词要用主动语态；反之，如果主语是动作的承受者，动词就要使用被动语态。 被动语态谓语部分结构为助动词be + 过去分词。

34. 各种句型的被动形式 重点内容 肯定句 主语 + be + 过去分词 + （by …） 否定句 主语+ be not +过去分词 +（by …） 一般疑问句Be +主语+过去分词 + (by …)? 特殊疑问句 疑问词 + be +主语 + 过去分词 + （by …）？ 注意：这里 be的形式决定了被动语态的时态，其后的过去分词没有变化。

42. 2. It’s used for scooping really cold ice cream. • 它是用来舀十分冰冷的冰淇淋的。 • 句型be used for意为 “被用来做……”,介词for表示用途,后接名词或动名词。如: (1) sweater is used for keeping warm. 毛衣是用来保暖的。 (2) The knife is used for cutting. 小刀是用来切削东西的。
