Overpopulation causes crisis on the earth, for instance, shrinkingof the natural resource, worsened environment, shortage of food and water（跟资源短缺重复）,heavy burden of welfare of the governments and so on. On the other hand, humanactivities cause disastrous impact on the animal world: extinction of them is at a terrific （这个词貌似是褒义词啊）speed. There is a fierce discussion on that （多余）whether it is moreimportant to reserve land for human beings than for endangered animals. For mypart, I don’t think neither side is of more important.（双重否定用错了~~您的意思应该是我认为没有任何一方比另一方更重要，所以要删掉don’t）

It can be imagined that being lack of land for human dwellingor planting food will lead to disastrous consequence. However, humankind is not the exclusive species on the earth which is composed of plants, animals and us.We human beings have well (比较级)developed brain than any other lives and are the wisest species on the world. It is our responsibility to reserve land for the animals that strongly rely on the environment they inhabit, and some of the animals have resided on the earth for a longer time than human.（这句用意不明显，要解释清楚这些动物比人类存在时间长和人类不应占它们地的关系）) y.

真是不好意思，前几天有点事没有及时改作文，今天补上！！！望楼主见谅
A large amount of movies are produced each year, which cover varies of themes,such as love, wars, social problems, humanity and so on. Some people hold the point of view that we should watch those serious ones that help people think than to those could only amuse and entertain people. As for me, the former（一般用在之前有论述2个事物的情况下，指前者，而你这里之前只论述了一个观点） perspective is coincidental with mine for the following reasons.
f9 r, q# Q+ t
Firstly,one of the basic functions of the movies is to amuse and entertain people, no matter which type of the movie is. Thus, both the brisk comedies and the serious movies which reflect the severe problems of the world and individuals could help people to relax themselves. The good examples are those movies won the Oscar, “Forest Gump” is one of them which was a comedy told a disabled boy succeeded by the accumulation of small and lasting effort. The movie was shot at a humorous angle, and I could remember we watched the movie with laughs. However,the very movie gives voice to us that patience, braveness and kindness of the success of ordinary people.（that 后面怎么没动词啊~~不明白这句话的意思）
Obviously, we could say this film not only amuse us but also convey some serious meritsto us. Nevertheless, the pure recreational films only deliver us the content of entertainment but（后面的短语是修饰content吧~~那么but可以省了）
without any deepmeanings.$ `" l. _  @; m( M  x7 \) O/ ^1 G
Another important factor is that, those serious movies provide us materials could cause us to（没有cause sb to do sth） deeply think about the essence of the whole life. （用特技和思考人生有什么联系？是不是要过渡一下）Some films are of elaborate shooting techniques which employ the advanced scientific technologies. Take the film “Crash” as an example, which is composed of detached stories referring different persons. Kin relationship, racialism, problems of the adolescents,and even wars are discussed in this film. We make a deep reflection of those events of the films and we may change our society toward a better direction.(we是谁？？这句话不明白)Last year, there was a heat discussion about the 3D film “Avantar” which stimulates the directors use more advanced technologies to produce films with more grand vision effects.（这段完全偏离主题,为什么除了第一句后面都是特技了）
t8 s
According to （what）I have mentioned above, those serious films have more merits than those could only entertain us. The serious ones offer us the mental and physical enjoyments.
大概看懂了楼主的思路，第一段想说严肃和喜剧都可以娱乐大家，第二段是讲严肃好于戏剧在内容深刻上。但是尤其是第一段，观点不是很明显，最好强调严肃剧也可以放松身心，因为大家的普遍观念是喜剧更能使人放松。第二段论述有些混乱。还有就是文章有些语法错误，语句连贯性不好，不过有用些高级词汇。
