原文
Nowadays, people are paying more attention to health. They often do morning exercises to keep fit, eat healthily, and go to bed early. However, despite these efforts, some people still falls ill easily. One of the main reasons is because they lack of exercise. Another reason is their irregular diet. For instance, some people like to eat junk food and rarely eat fruits and vegetables. This kind of diet is harmful for our health. In addition, some people don't have enough sleep. Lack of sleep can lead to many health problems, such as headache and tired. Therefore, we should try to keep a balanced diet, take regular exercise, and ensure adequate sleep.
文章概要
本文讨论了现代人对健康的关注，尽管许多人通过锻炼、健康饮食和早睡等方式来保持健康，但仍有部分人容易生病。文章分析了其中一些原因，如缺乏锻炼、饮食不规律以及睡眠不足，并给出了相应的建议。
答案解析
错误1：falls - 更正为 fall
解析：主语"some people"是复数形式，因此动词"fall"也应使用复数形式，但动词原形"fall"在第三人称单数形式时并不加"s"。
错误2：because - 更正为 that
解析：在句子"One of the main reasons is because they lack of exercise"中，"because"用于引导原因状语从句，但此处是一个表语从句，表示原因，因此应使用"that"来引导。
错误3：lack of - 更正为 lacking
解析：在句子"because they lack of exercise"中，"lack"作为动词时，后面不需要加"of"，而应直接使用"lacking"作为形容词形式，或者改为"because they lack exercise"。
错误4：tired - 更正为 tiredness
解析：在句子"such as headache and tired"中，"tired"是形容词，表示"疲倦的"，而在此处需要的是一个名词，与"headache"并列，表示健康问题的一种，因此应使用名词"tiredness"表示"疲倦"。
以上就是英语四级改错示例，在英语四级备考中，需要保持持续的学习和练习，不断提高自己的英语能力。
