帮我检查一下这段英语语法和字母有没有错误

麻烦帮我检查一下这句英语是否有语法错误(附更正)~

请补全问题，我是英语本科生，四级分数547，虽然分数一般，但是足以解决基本常见英语问题

hi，这个句子有一些问题：
Personally I believe that with the development of society.（后面缺句子，随着社会的发展，然后呢？一般是with the development of the society, more and more people are becoming.....）
If every member is willing to contribute himself to the society，than I am confident that a bright future is waiting us
(这句话你想表示的是，只要人人都有奉献意识，等着我们的一定是美好的未来，你想看每个 人为什么一定是男的呢，所以你这个himself是有问题的。改成这样比较好：
If everyone is willing to make contirbution to the society, then I am confident that a brighter/better furture is waiting for us.)
直接用make contribution to 贡献,就避免了不知道用him 还是Her 的问题了
wait for sb 等待某人一定要加介词for
这里我用的 brighter 比较级是想表示一个更美好更明朗的未来。你也可以直接用bright。

B: I suggest you to have some medicines.
我建议你去吃些药
C: Yeah,i did,but it is little better than before.
是的，我吃了，但只比以前好了一点

应为:
B: I suggest you to take some medicines.
C: Yeah,i did,but it was just a little better than before.
[时态要保持一致，前面说了did,表示已经吃了，后面要用was]

C: I did all you say.
你说的我都做了

应为：I did all you said.
[已经说了，再做的，所以say用said]

C: I fell bad today.
我今天感到不太好
[这个是你打错了吧？feel或者felt都行，前者比较严谨]

B: Well,you ought to drink lots of water and keep enough sleep.
噢，你应该喝多点水并且保持充足的睡眠

[充足睡眠应为：keep an adequate sleep，enough sleep有汉化成分]

打错字的就不说了吧，如果有用请采纳，谢谢！

B: I suggest you to have some medicines.
我建议你去吃些药
C: Yeah,i did,but it is little better than before.
是的，我吃了，但只比以前好了一点

1.一般吃药用take some medicines,而不用have.
2.如果想表达“只”，则应该加上just。并且little前应该有a。所以是but it's just a lttle better than before.
--------------------------------------------------------------------------------------------------------
C: I did all you say.
你说的我都做了

另外，这个句子本人觉得无语病但别扭。建议加上as。 I did as all you say.
仅供参考

倒数第六句英文，是“you should”;还有倒数第二句英文是“You're”,除此之外没有什么问题，希望这些能帮到你。

我觉得很不错

哦，我相信你的没错，谢了~~~~(>_<)~~~~ 我会尽量采纳的
还有，应该是I feel bad today 还是i feeling bad today?
这句话我没有给你改。不过惯用法一般是I‘m not feeling very well. 一般feeling前应该有系动词。
