易错句子Round the price into the nearest dollar.
正确表达Round the price to the nearest dollar.
表示“四舍五入到某个数值”时,round 后面固定用介词 to,不能用 into。汉语的“到”常被直译成 into,但 into 表示“进入某空间或变成某状态”,不能用来引出取整的目标数值,所以应说 round ... to the nearest dollar。

易错句子The car rounded around the corner and disappeared.
正确表达The car rounded the corner and disappeared.
round 表示“绕过、拐过(弯)”时是及物动词,直接跟宾语 the corner,后面不再加 around。学生受汉语“绕过”这种“动词+补语”结构影响,容易给已经及物的 round 再补一个介词,造成语义重复;去掉 around 后意思不变。

易错句子Please round up it to the nearest ten.
正确表达Please round it up to the nearest ten.
round up 是“动词+副词小品词”构成的短语动词;当宾语是代词 it/them 时,代词必须夹在 round 与 up 之间,即 round it up,不能放在 up 之后。宾语是名词时两种位置均可(round up the number / round the number up),但代词只能放中间。
本组反义取 round 作动词的“使成圆形/弄圆”之义。straighten 指把弯曲或圆曲的东西拉直,与 round 的曲线义相对;flatten 指压平,square 指加工成方形/直角。这些反义仅适用于具体形状变化的语境,不能用于 round 的“四舍五入”“绕过”“完成”等义项。
