英语作文批改张楠的父亲有位美国同事,他的孩子约翰?史密斯即将来华.约翰写信向张楠询问一些有关他所在城市的问题.张楠回信,

1.I'm glad to know your son John Smith will arrive to (改为 in) china!
到达某地应该用 arrive in (大城市或国家),arrive at(小城镇或农村)
2.Let me tell you something that different from USA.
句子不通,有两种改法：
1）改为 something + 形容词短语——Let me tell you something different in our city from that in yours.( 所不同的不是美国与 something,因为国家和事情不能类比,改为指代 something 的 that in USA 就可比了)
2) 改为 tell sb.about sh.——Let me tell you something about the difference between our City in China and yours in USA.（用名词 difference）
以上两种改法都另外加上城市,用以直接点题.
3.The first is （the）climate.（只这里的气候,是特指）
4.In this city,with snows sometimes,it is very cold in winter ,and it rains rarely ,but hardly had it rained,then it would very large.
句子较长,其后表述有些脱节,改动如下：
In our city,north of the lower reaches of the Changjiang River(用江北作同位语,以说明下文冬天既下雪又下雨的特殊气候现象,不然下文有些唐突) ,with snows sometimes,it is very cold in winter raining rarely（分词短语作陪衬状语）；however（比用 but 更为妥贴）,did it rain,it would very be very heavy.
1) 注意不要混淆 hardly...when/before 和 no sooner ...than 中的关联词.不过这两种用法用在这里都不妥,应该改为条件虚拟语气,改动处还是用了倒装句.
2）大雨只能用 heavy,不能用 large.
5）So you should have John （删去to） carry （the 改为 an）umbrella.
1） 使役动词动词 have,make 和 let 后用不定式作宾语补足语都不带 to.
2) the umbrella 双方心照不宣的雨伞,an umbrella 任意一把雨伞.
6）The second is food,it is a lot of different from USA,so John should try to adapt to the Chinese food.
改动如下：
The second is the food here.It is quite different from yours,so John should be ready to try to adapt himself to the Chinese food.
1) 还是要注意上面提到的可比性；
2）Tom 还没有到怎么去适应呢,所以添加 be ready to 建议有思想准备；
3）adapt 是使役动词,adapt sb.to sth.使某人适应某事
7）In addition,he must learn （to 多余） how to use chopsticks which is the tool to eat （in China）.
8）Finally,please (添加 remmember to) carry a USA's map,(添加 for I'd like to know more about your country) .
9) I hope we'll see each other as quickly ( 此处还是用 soon 为好) as possible
