IV. Language studies

长难句分析：

1. Luckily, a solution was born in the form of the 2-D barcode.

句意为：幸运的是，一个解决方案诞生了，那就是二维条形码。Be born in the form of的意思是“以……的方式诞生”。

2. Looking like lots of small black and white squares in an area similar to the size of a stamp, the 2-D barcode can be seen everywhere - on magazines, buses, business cards - almost any object that users might need information about.

这句话的主干是the 2-D barcode can be seen everywhere。Looking like…用作伴随状语，其逻辑主语是the 2-D barcode。句末的that…是定语从句修饰前面的先行词any object，that代替先行词在从句中作介词about的宾语。句意为：二维条形码看上去像许多微小的黑白矩形图案嵌在邮票大小的区域里，人们到处都能看见它——在杂志上，公交车上，名片上——它几乎被应用于所有需要相关信息的物体上。
