网友回答
(答案→)students改成student
解析：文章介绍汤姆是个勤奋的学生，周末都不休息，但是因为太疲劳效果不好，爸爸建议他好好休息一下，全家人到郊区野餐，放风筝，玩得很愉快，星期一，汤姆也能精力充沛的上课。
【小题1】汤姆是个高二学生，因为是单数，所以students改成student
【小题2】在晚上，他在家学习到深夜。因为是上个星期六的事情，用一般过去时：studies改成studied
【小题3】他太困太累以至于不能有效的学习。这里用so…that句型：too改成so
【小题4】在星期天的早上用介词In
【小题5】他刚要学习这时爸爸过来建议他休息一下。词组：have a break休息一下
【小题6】他们买了一个非常喜欢的风筝。这句话用了定语从句，先行词是kite，定语从句省略的关系代词，所以定语从句中应该缺少宾语，去掉it
【小题7】他们到了郊区，在那里汤姆自己玩放风筝。Enjoy后面接动名词：fly改成flying
【小题8】全家人一起野餐，在户外感觉很放松。这两句话是并列关系：but改成and
【小题9】星期一的时候，汤姆在教室里面精力充沛很积极。和energetic并列做表语，应该是形容词： actively改成active
【小题10】他说这只是因为他度过了一个很好的周末。This is why“那就是为什么”，改成That is because“那就是因为”
