汉译英:今天他们一起去上学

【翻译】
Today they went to school together. [上课完了]
Today they will go to school together. [将要上学]
They went, in pair, to school today.
【说明】
* 由于汉语中没给出时态，因此有不同翻译。
* Today they go to school together.没语法错误，但现实中没意义。
* 最后一句很有文采。首先，in pair表示一对，可能是好朋友或者情侣哈。其次，in pair作插入语，很地道。

Today they go/went to school together .

Today, they go to school together

- -他们不一定是两个人，可是in pair就是两个人啦。
有一点点画蛇添足。

Today they went to school together
