Question

一个英语被动语态的语法问题，请高手解释。

1。extra expenses are to be borne by you. （原句）
2. extra expenses are borne by you.
这两句的区别是什么？ 为什么要用are to be borne ?
extra expenses will be borne by you. 与原句的区别

Answer 1

我的理解是：
1.是指“多余的费用由你承担！”而不是指2.“多余的费用由你产生！”人一般是不会“生”钱的！
注释：
borne
不作“产，生”解的 bear1 的过去分词。★在作“产，生”解时只限于生育(子女等)一义，有以下两种情况：一是用于完成时，置于助动词 have 之后；一是用于被动语态，置于介词 by 之前。 She has borne two children. Two children were borne by her. 她生了两个孩子。

Answer 2

"to"具有后时性，也就是说to be borne说明bear这个动作还没有发生。
而第二句则已经是一个事实了。
翻译过来就是：
1.额外的费用将要由你承担。
2.你承担而外的费用。

Answer 3

不定式 (inf.) to be 表式将来。be done 表被动。

Answer 4

to be means for future.both means the extra expenses should be borne by you.

Answer 5

将来时？！
