English中问题
1.The series of book is very interesting.这句子中是否有误?我有疑问的是book是否加s,is是否改为are?
2.翻译：士兵们从急流中救出那几个男孩,我们为他们感到自豪.
----That boy was rescue by the soldiers from the rapids,we were proud of them.
我认为应该改为：（不知道“急流”-rapid是否可以加s ）
The soldiers rescued those boys from the rapids ,we were proud of them.(请帮忙评价）
我认为此句原翻译的句意不对，

Answer 1

“book”后面应该加s,is改为are
好像“急流”本来就是rapids（英语书后面的单词表里是这么写的）
“was rescue”应该是"was rescued"
