英语小问题<翻译>

Luckily ,I passed the examinations of all the subjects

Fortunately, I passed all classes.
就这么简单

Fortunately,I passed all the exams.

Fortunately, I have passed all the tests of all the subjests
或者说学科就不要说了，因为所有的考试就暗示了所有的学科
Fortunately, I have passed all the examinations.

如果你的英语水平高点的话，你会觉得楼上两位说的其实都对。除非你是高中生，为了强调语法，It is fortunate that I pass the examination of all the subject 。
