LaTeX技巧671：LaTeX编写带答案的练习薄

通常，我们写练习题都是没有答案的，所以，我们想提前写好题目和答案，需要答案时再打印出来。是比较好的解决方案。 

 1，这里推荐一个比较好的类https://code.google.com/p/exercisesheet/下载地址：https://code.google.com/p/exercisesheet/downloads/list其代码：git clone https://code.google.com/p/exercisesheet/

2，exsheet 做得也是很不错的, 下载地址如下：https://bitbucket.org/cgnieder/exsheets/wiki/Home 参考：http://tex.stackexchange.com/questions/70599/problem-solution-environment

3，使用 answers 包来实现：

选自：http://tex.stackexchange.com/questions/301/how-can-i-produce-exercises-in-one-part-of-a-latex-document-with-selected-answer

代码如下：

\documentclass[12pt,openany,twoside]{book} 
\usepackage{fouriernc}
\usepackage[thmmarks,standard,thref]{ntheorem}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{answers}

\theoremseparator{.}
\theorembodyfont{\upshape}
\newtheorem{pro}{Problem}[chapter]
