1.第一句 life改为 lives复数形式
2.第二句开头定冠词The 改为冠词A
3.第三句说法不妥当 不可以说you will have an effect on sb.optimistic的冠词应该是an 本句改为 And your optimistic mood can influence people around you as well.更为妥当.
4.第四句 句首It''s 表达不够明确 其实这个it应该是代替to have a good mood.但是前文中并没有用到过to have a good mood 作主语 所以此处不可以简单的用代词it代替 这句话话句末加上to have a good mood.
5.第五句 you may be fail in something or something like that 十分不通顺 首先 fail in something前不加be 你写道 is that 应该是明确表达确定的某一个原因 是单数 而你后面却又含糊其辞 原因并不够明确 而且可能不止一种 这样极为不妥 建议本句改为：The reason why you sometimes have a bad mood might be that you failed in something.
6.第六句 things' 罕见这样的复数形式 side 也应为复数 改为 about the bright sides of things.
7.第七句中间不可以用逗号隔开 因为都好两端是两个完整的句子 而不是短语或句子片段.所以中间应该用句号 或者分号隔开 或者 把Maybe 改为When.
8.第八句 we being in the trouble 应该改为when we get into trouble 后面 cames 首先过去式不加单三s 其次 这个地方应该为一般现在时 因为你前面没有明确说明过去时间 所以改为comes
9.第八句和第九句没有明确因果关系 不可以因为坏心情会在我们不知道的情况下来临 所以我们必须保持好心情 因果关系不明确 所以 应该把So删掉.如果坚持要用So,最好把so前面改为逗号.
10.第十句是口语化因为没有主语 严格来说语法是错误的 比较牵强附会 专业论文中绝不可出现 请楼主自行权衡
