The No.2 elementary school of Shixianzhen in Tumen
The No.2 Middle school of Shixianzhen in Tumen
The No.1 senior high school of Tumen
华师大一附中实验中学
直接用一个of把上面的那些英文名称连起来就可以，译作：
experimental middle school of no.1 high school afflicated to east china normal university
中学在美国一般译作high shool，主要是指高中，初中可以译作junior high school, middle school也比较常用，尤其是在英式英语中。secondary school 当然也可以，但没有上面那些说法普遍而已~
我是英语专业出身的，希望可以帮到你~
