3.B
翻译：有两张大的画像挂在墙上.
此题考查完全倒装句型.
该句型要求把做状语的介宾短语提前,加上谓语动词（一般是不及物动词）,在加上句子的主语（必须是名词/名词短语）,即：介宾On the wall + 谓语动词hang + 主语two large portraits.
其正常句序为：Two large portraits hang on the wall.
此句主语two large portraits为复数,排除三单的A；
hanged做谓语动词（过去式）时,其意思只能是“绞死/吊死”,且为及物动词,句意也不通,排除C；
D如果做正常句序的句子的谓语没有问题,但是其倒装句型不能如此使用,必须改成：Hanging on the wall are two large portraits.
4.A
翻译：--当Tony给你打电话时,你正在做什么?--我刚刚完成了工作,正要去洗澡呢.
此题考查时态.
由问句的What were you doing即可判知答案最好用I was doing sth.
