ANSWER: 

Some people suggest that schools for young children should recruit only pupils of similar interests. However, I believe teaching by enrolling children in a school where peers have a variety of interests will be better for them.

It is argued that interests are the source of motivation. When children are given a favourable environment to practice their interests, their academic performances can be improved due to the maximized motivation. Furthermore, they would feel it is easier to make more friends and are therefore feel more joyful. 或者这么说：they would feel (more comfortable)/(at ease) making friends and hence feel more joyful.

Despite these advantages of educating children in such an environment, I still prefer otherwise for the reasons below.我想你要说的是你'比较同意以下的看法'：I still stand by my own opinions as stated below. Firstly， children in their early age tend to change their interests easily or develop other new interests. In a school where their mates have other interests, it is likely that they can be inspired by their mates to have other interests. This helps them to explore the potentials notthat are yet to be discovered. Secondly, these children can be taught by their everyday experience to understand and handle the differences. 这句子我帮你改成：these children could learn how to handle and be tolerant of differences between themselves and other children. 但是原本的意思就不在了。所以你可能比较想要表达的是：these children could teach themselves how to understand and handle differences between themselves and other children through everyday experiences in school.This is of significant importance for a becoming sociable and healthy adult thatwho is able to cope with people who are different from them in other aspects. Finally, this nurtures children’s tolerance. The world is still far from being peaceful and one of the most important reasons is that people of different political or religious backgrounds sometimes goes into war due to the differences in their interests. Experts believe that children brought up in such schools are more tolerant in their personality.

In conclusion, I am convinced that children educated in schools that have pupils of various interests enjoy a number of more important merits than those in schools that recruit pupils of similar hobbies. I propose that teachers should help children to learn about the differenceshow to be tolerant of their differences with other people and encourage them to try something different in such schools.

"I'm very glad to make friends with you

Hello everybody ,My name is Zhangzhenyu.I'm from Mianyang City ,Sichuan Province,China.I want to make friends with you。Also,I want to make friends with foreign people more。And I can prove my English skills.Can you help me ? "

"I'm very glad to make friends with you" - 这样的说法意思是说你已经和我交朋友了所以你很开心。我想你想要说的是 '很高兴如果能够和你做个朋友'对吗？应该是：'I would be glad if we could become friends'. 

"I want to make friends with foreign people more." － 以我能够理解的是你比较喜欢和外国人交朋友。这样的说法比较恰当：'I would prefer to make friends with foreigners'

"And I can prove my English skills"－ 这句子意思中文翻译是 '我可以证明我的英文水准'.如果你想要说的是'你可以清楚理解我的英文水在那里' ：'I would prefer to make friends with foreigners because（因为）they could 

guage my level of proficiency in english language。' 因为这句子开头是'And'，我就想说那两个句子应该是连在一起的吧。
