再请高手帮助我翻译这小段计算机英语，非常感谢！
one advantage of. net is that it provides a lot more security than the
base windows operating system: the managed environment is often referred
to as a "sandbox" where applications can only do what they're authorized and authenticated to do. the.net framework is also fast,
efficient, and multi-language,meaning that you can write applications in a number of languages,including visual basic, and c#,which is a new
language that combines the productivity of visual basic with the
fine-grained control offered by c++.
参考答案:.net的优势之一是比基础视窗操作系统更强大的安全性，即在被称为“沙盒”的管理环境中应用软件只能在授权范围内运行。同时，.net结构也是快速、有效、多语言的，这意味着你可以用包括visual basic和c#的多种语言编写软件。其中c#是一种新语言，它同时具备了visual basic的强大功能和c++的精确性。
