刚写的OG上关于无私的作文，请版主帮忙看看

我觉得要克服使用笔记上那些原词好困难，所以写的时候不顺手，有时候自己实在说不出新鲜词，只好照用，会扣分吗？还有字数也只能达到200出头，怕不够。请版主赐教。

The lecturer talks about the benefits of meerkats and humans（不要s） through some activities to demonstrate that there is no altruism in such behaviors. In this way, the main idea of the passage is refuted by the lecturer.

In the first place, the lecturer mentions a study about meerkats which reveals that this animal does not take on the responsibility of guarding without eating（否定太多了，句子很awkward）. On the contrary, it eats in advance. This fact is in conflict with the passage which says that the meerkat on guard has nothing to eat while it has to help others（从句套从句，还跟在with后面，结构不好，句意不清晰）. What's more, the lecturer also offers the information that just because of the chance to be a guard, meerkat could run quickly into the burrow near it and take the advantages of the other meerkats which are running all directions. Obviously those poor creatures will draw attention of the enemy and protect the guard. This is described as a high risk mission in the reading while it's not the truth.

In addition, donators are not so great in the lecture considering their gain, I mean, the respect of society. It is those donators who receive the pride and fame as feedback of their behaviorS. This also contradicts the information from the passage that donators receive nothing（歧义，从句修饰啥的？）.
