帮忙把下面的内容概括一下大体意思
Hi Ben,
A new student joined our class today.She comes from London.Is Oxford like London?They are both cities in England,but I guess that doesn't mean they are like each other She doesn't know much about Oxford,except that it has a famous university.We've been e-mailing each other for a while but you haven't told me much about Oxford and I haven't told you much about LA.That's what we call Los Angeles.So I will tell you about Los Angeles now.You can tell me about Oxford when you write back.LA is one of the biggest cities in California.
There are about 10,000,000 people here.We learned in school last week that in 1900 there were only 100,000 people here.So it has grown fast.It is mostly sunny here.It gets very hot in the summer-up to 28℃.It doesn't get much colder than 9℃.In summer we often get a thick smog beacuse of all the petrol fumes from the cars.The heat,the way the land lies and the way the wind blow all make it worse.Some people even wear masks on bad days beacuse they don't want to breathe it in.Do you have smog in Oxford?
Eric

本 你好,
我们班今天来了一个新同学.她来自伦敦.牛津和伦敦差不多吗?它们两个都位于英格兰,但我猜那不是说它们很相似.她对牛津了解不多,只知道它是一所非常有名的大学.我们已电邮了一段时间,但是你一直没有跟我说太多关于牛津的事,我也没和你谈论太多关于LA,也就是洛杉矶的事.那么现在我就和你说一说洛杉矶.你回信的时候也可以和我说一说牛津.洛杉矶市加利福尼亚最大的城市之一.
这里大约有1亿人口.我们上周在学校里学到在1900年这里只有100万人.所以人口增长很快.这里大多时间都是晴天,夏天很热,气温会上升到28摄氏度.冷的时候,气温不会超多9摄氏度.因为汽车尾气,夏天这里烟雾很多.高温,地势,风向使这种情况变得愈发糟糕.在空气质量较差的时候,很多人会戴口罩因为他们不想吸入烟尘.牛津有烟雾吗?

再问： 能不能简短的概括一下？谢谢
再答： 作者向艾瑞克介绍洛杉矶的情况并向他咨询有关牛津的情况
