Online language programs keep students interested by ______.
A．supplying them with healthy diet
B．rewarding them With lower tuition
C．shortening the learning period
D．offering funny games as rewards
参考答案
正确答案：D
解析：该句中的crossword puzzles...games均属于有趣的游戏，表明为了让学生保持兴趣，语言程序给他们提供这些游戏，D符合文意。A利用diet一词进行干扰，原文提到dieting是为了说明学习语言像节食一样难，A与原文不符；B、C的lower tuition和shortening均无原文依据，可排除。
