今天早上我完成了第一堂考试i finished my first exam this morning,不能加介词在this that的前面，只能说this morning,今天早上我就要考试i will take an exam this mornig,考试不说meet an exam,exam前面要用an不是a。在这两个句子中第一个句子是过去式，第二个句子是将来时，但是这个两个句子都不需要用到be动词的过去式was.

Using "was" became passive. (in) This morning i finished my first exam - My first exam was finished this morning ( I is understood) (in) This morning i will begin to meet a exam - I will take an exam this morning ( it is a future tense ) " i" should be in capital letter, always. The first letter in a sentense must be in capital letter, always
