答案和解析
基本同意前边的回答,详细解释下,第一个解答是个人观点,不能保证正确:
1)"has been already"这种顺序似乎不太正规,already是修饰某种动作的副词,一般在过去分词之前(have/has already done)或句末,所以此句真要用现在完成时的话应为:Mr.Li as well as two sons has already been in the waiting room./ Mr.Li as well as two sons has been in the waiting room already.
另外,个人认为这句不适于用现在完成时,already用于现在完成时一般是强调动作的完成(如:* She had already left when I phoned.我打电话时,她早已走了.* I've already seen that film.我已经看过那部电影了.),所以,像这种表示状态的句子只要用一般现在时或一般过去时就能表达“已经”的意思,如:The teacher was already in the room when I arrived.我到的时候,老师已经在屋里了.
2)当两个名词或代词由as well as连接时,其谓语动词的单复数由as well as前面的主语决定,这是主谓一致的法则之一.举例:
The teacher as well as the students was reading in the library.这位老师和学生们一起在图书馆阅读.
The students as well as the teacher were reading in the library.学生们和这位老师一起在图书馆阅读.
遵循同样法则的还有:with,together with,except,but,like,rather than,more than,no less than,besides,including等,也就是说谓语动词的单复数不受这些词组的影响,这类短语只用作修饰语.
以上~建议好好研究下时态和主谓一致这部分的语法,有问题多问老师啊,以前班里都是一下课老师就被围住了(貌似走题了……
