Take a look at both sides before you cross a street.Take a look at both sides ofroad before you cross a street. 应该这样吧- -不用了，后面已经明确说明是street，再说road就是画蛇添足了。或者你这样说也行：Take a look at both sides of the street before you cross it.Before you cross the street, you must look at the left and right.我觉得这样更好，只是没把注意翻译出来这位不知道是大姐还是大哥的童鞋........翻译句子不是逐个翻译单词啊，非要变成chinglish才甘心么......你就按照你自己觉得正确的写吧.......我承认我是有点钻牛角尖....
