我们每天上课前有一个Duty Report,我找好了一篇文章,请帮忙修改一下语法错误,并精简一下可有可无的句子,或让句子语法简单点（七年级,不要太难）.
Tom's father wants to know how his son is getting along in school.One day he asks Tom:”Tom,how are you getting along in school?What’s your place in the class?” “Number Twenty-one,father.” “And how many students are there in your class?” “Twenty-one.”
One Saturday afternoon Tom gives his test paper to his father.“I am getting along better now,father.” “What’s your place in the class now?” “Number Twenty now.” “Good,then you are one place in the class now?” No,father,one of the students isn’t in our class.He studies in another school now.”
还有,并给出相应的答案!（我想的是Tom有没有进步,但不知怎么说...
getting alone 在这里怎么翻译？
