(1)教室必须每天被打扫。
The classroom ____ ____ ____ every day.
(2)水稻不应该种在山上。
Rice ____ ____ ____ on the hill.
(3)废纸不应该被扔在这儿。

答案：
(1)must be cleaned
解析：“必须被打扫”用“must be cleaned”，must表示“必须”，be cleaned是被动语态。
(2)shouldn't be planted
解析：“不应该被种”用“shouldn't be planted”，shouldn't表示“不应该”，be planted是被动语态。
(3)shouldn't be thrown
解析：“不应该被扔”用“shouldn't be thrown”，shouldn't表示“不应该”，be thrown是被动语态。

B. 句子转换
(1)We should plant more trees. (变为被动语态;变为一般疑问句)
____
(2)Teenagers under 18 should be allowed to drive. (变为否定句;变为一般疑问句)
____

答案：
(1)More trees should be planted by us.
Should more trees be planted by us?
解析：主动语态变被动语态，把宾语more trees提前作主语，谓语动词用“should be planted”，by us放在后面；变一般疑问句把should提到主语more trees前面。
(2)Teenagers under 18 should not be allowed to drive.
Should teenagers under 18 be allowed to drive?＜/解析：否定句在should后面加not；一般疑问句把should提到主语teenagers under 18前面。

2. across
解析：“穿过马路”是从表面穿过，across表示“从表面穿过”，符合语境。
3. Cross

2. wasting
解析：“regret doing sth.”表示“后悔做某事（已做）”，浪费时间玩游戏是已经发生的事情，所以用wasting。
