问题描述：
to being done 与 being done 区别
Now English is one of the foreign languages ________ in high schools in shanghai.
A to being taught
B being taught
是不是两个都能选?
怎么区分.帮下,感激不尽!
答
A是肯定错误的。
选择B
being done做后置定语，表示某事正在被做。
而第一个表达中 to是介词，句子已经没有意义了。
不知道你可明白？
答
答案：B.
翻译：现在英语是上海市中学被授的外语之一.
1.分析句子结构可知,____ in high schools in Shanghai为后置定语,修饰句中的表语foreign languages.
考虑被修饰词foreign languages和非谓语动词teach之间为被动关系,且后者所表示的动作当前正在发生,所以用being done做后置定语,即B为正解.
2.A的结构有误.
如果to是不定式符号,则其后不可能紧跟Ving形式的.如果是to be done（即to be taught）,则其表示该动作当时尚未发生,也不符合句意.
如：I will attend the meeting to be held tomorrow morning.
3.此时只能将to理解成介词,但是又没有句中此种结构搭配,由此排除A.
A类的结构试举一例给楼主看下：
I‘m looking forward to being sent to work in a big city like Shanghai.
我盼望被送到像上海这样的一个大城市中去工作.
