I II III 首页 目录 回归教材·知识梳理 课堂达标·高效提能 词汇盘点·素养积累 Each number in a barcode is shown by seven blocks of the same size.These are colored either black or white to show the number zero to nine.For example，the number “one” is shown in turn by two white stripes(条)，two black stripes，two white stripes，and one black stripe.Even if you turn it upside down，it isn’t similar to any other number. I II III 首页 目录 回归教材·知识梳理 课堂达标·高效提能 词汇盘点·素养积累 A barcode includes different parts and each one provides a specific meaning.The first part of a barcode tells you the country where the product was made.For example，690－692 is the barcode for China.The next part tells you who produced the product.The final part is about the product itself.This is how barcodes work.
