the right.向左拐，医院就在右边。You have to turn right here.你必须在这里向右转。【拓展记忆】1）turn还用过连系动词，意为“变得”，相当于become。例如：In autumn,the leaves turn yellow.秋天树叶变黄。2）left还用作名词，意思是“左边”，其反义词是right，意思是“右边”。例如：Look at the picture on the left.请看左边的这幅图画。It is on the right of the garden.它在花园的右面。2.Go along Long Street and its on the right.沿着长街走，它在右边。【重点注释】on the right在右边，on ones right=on the ritht of在的右边；on the left在左边，on ones
