【解析】有压力的学校生活和不健康的生活方式对学生会引起一些问题。坐的时间太久引起一些疾病，建议每小时站起来活动五分钟，不要发信息而是亲自送去；吃饭不规律睡眠太少，建议吃健康的食品，每天按时吃饭，晚上睡八个小时中午休息30分钟。

1.句意：如此多的家庭作业和电脑游戏使学生坐几个小时不站起来活动，make sb do sth使某人做某事，是一个固定短语，故用动词原形sit

2.句意：不站起来走动。Without介词，没有；介词后用doing,故填standing

3.句意：每小时站起来活动五分钟是必须的。It’s +形容词+to do做某事是什么样的，是一个固定句型，故填to get

4.句意：繁重的学习和压力妨碍了学生有规律的吃饭和足够的睡眠。Prevent ---from---预防，阻止，妨碍；from是介词，后用doing，故填eating

5.句意：不健康的生活习惯被学生具有。develop动词，发展，具有；Unhealthy eating habits做主语，应是被发展，被具有，故用被动语态，被动语态结构是be+过去分词， habits是复数，故用are,所以填are developed

6.句意：记住一天按时吃三顿饭。remember to do记住去做某事，是固定短语；故填to have

点睛：用所给单词的适当形式填空补全短文，要注意上下文的联系，句子的语态、时态、人称和数的变化、词性、固定短语等。例如小题5，句意：不健康的生活习惯被学生具有。develop动词，发展，具有；Unhealthy eating habits做主语，应是被发展，被具有，故用被动语态，被动语态结构是be+过去分词， habits是复数，故用are,所以填are developed
