英语简单句子翻印
it is a little boat which has sailed across the Atlantic many times.
这里面有个which 在这里做什么啊?
Topsail(船名) be in the race across the Atlantic.
Topsail(船名) was in the race across the Atlantic.
这两个句子 be was 是什么作用啊?是干什么的?
请翻印一下这三个句子.小弟刚学英语,答的好有追加.

答案

it is a little boat which has sailed across the Atlantic many times
这个句子是个强调句型,which 指代little boat,意思为就是这只小船已经穿越大西洋多次.
Topsail(船名) be in the race across the Atlantic.
这是个虚拟语气的句子,省略了should这个助动词,意思为Topsail本应该在穿越大西洋比赛的途中.而这句话本身隐含的意思却是这艘般并不在穿越比赛中.
Topsail(船名) was in the race across the Atlantic.这句话却是另一种意思,是一个一般过去式,意思为Topsail曾出现在穿越大西洋的比赛中.
