Answer 1

【答案】

【1】 aren't allowed　

【2】 What's made　

【3】 isn't watered

【4】 How are

【5】 is heard to

【解析】

【1】句意：学校不允许我们没有老师就进入化学实验室。主动语态为一般现在时，改成被动语态后，时态不能发生变化。一般现在时态被动语态的构成am/is/are+及物动词的过去分词，主语是we，助动词用are，否定式为aren’t，后跟过去分词allowed，故答案为(1). aren't (2). allowed。

【2】句意：这辆自行车是钢制的。对材料提问选择疑问词what，后跟一般疑问句语序，故答案为(1). What's (2). made。

【3】句意：奶奶每周给花浇水。此句是一般现在时态的被动语态，变否定句直接在助动词is后加not，缩写成isn’t，故答案为(1). isn't (2). watered 。

【4】句意：那架模型飞机是手工制作的。by hand用手，对方式状语提问用疑问词how，后跟一般疑问句语序，故答案为(1). How (2). are 。

【5】句意：我们经常听到那个女孩在房间里愉快地唱歌。变被动语态，两个句子的时态不变，此句要变成一般现在时态的被动语态，一般现在时态被动语态的构成am/is/are+及物动词的过去分词，主语是The girl，助动词用is，hear的过去分词为heard；在主动语态中hear后跟省略to 的动词不定式作宾语补足语，变成被动语态后，必须加上to，故答案为(1). is (2). heard (3). to。
