第一个论点前面我觉得绕得太远了。
And the latter kind of people, we call them true friends.
这句我觉得直接不要了,然后前面的内容尽量压缩,把重点放在“真正的朋友不会因为竞争而影响友谊”上面来写。这个论点不是特别好写,你选得这些内容they helping us getting through the difficulties, taking care of us to rid the illness, or just hanging out with us to have fun.是可以的,尽量表现出竞争只是相处中的一部分,主旋律还是生活学习中互相帮助等等
What's more, in most cases, the competition among friends bring positive motivation to every. Competition is a process during which we don't merely focus on exploring our own potentials. In order to perform better, we need to learn from our competitors and even share with them. 然后加你的例子,但是记得要精简一点。然后最后的话再多加半句到一句的总结。
