we are lucky that parameter has been supportted

we are lucky that parameter has been supportted
这个句式怎么分析啊?

这种句型在英语出现的很多,语法学家也有不同的看法.在牛津版的初中课本中,把that从句看成是宾语从句.有些高中老师把它看成是状语从句.薄冰的语法书把它看成是做形容词的宾语从句.
lucky是形容词.
你可以根据自己的理解,看成是宾语从句或状语从句吧.
当然主句是we are lucky,从句部分是that parameter has been supportted
再问： 主句部分大都是It is + adj+ that, 而这里是we are lucky that,感觉怪怪的.有没有这种感觉? 但觉得从语法上应该没啥问题.
再答： 没问题的，这里有几个例子： 1.be lucky to do/be sth 　The children were lucky to survive the fire which destroyed their home. 2.lucky enough to do sth 　those of us lucky enough to own our own homes 3.lucky if 　I'll be lucky if I get any of my money back. 4.lucky (that) 　I was tremendously lucky that I didn't die in the accident. 5.lucky with 　We've been very lucky with the weather. 6.count/consider/think yourself lucky 　Count yourself lucky you've got a husband like Jack.。 7.resulting from good luck 　I didn't really know your name - it was just a lucky guess . 　A middle-aged woman had a lucky escape when a tree crashed down onto her car. 8.it is lucky (that) 　It's lucky that no-one was hurt. 9.bringing good luck 　a lucky charm 10.lucky you/me etc(spoken used to say that someone is fortunate to be able to do something) A：'My husband's a rich man, and devoted to me.'
