请帮我看看一下句子翻译得对不对。

一二句是对的，第三句he was playing basketball yesterday.可被视为过去进行时态，he playing basketball yesterday. 是错误的，应将playing改为played过去式，因为有过去时间状语yesterday。
第四句有两个谓语动词是错误的，如果想表达这个意思可改为He rides bike to go to school every day.或Every day he goes to school by bicycle。
第五句-第八句是对的。
第九句His older brother walks two kilometers everyday.
第十句His younger brother is a good boy.
十一是对的
十二He is on the phone
十三句he works hard everyday.
十四句是对的
十五句he used to be a good student
绝对手工，望采纳。。。

1.he was playing basketball yesterday.这个可以当做是过去进行时来理解！
2.he playing basketball yesterday。句子中的playing是一个非谓语动词，不能用作谓语！
3.他昨天骑脚踏车到乡下去。可以这样翻译;he rode a bike to the countryside yesterday.
4.他正在唱歌。he is singing.可以加一个宾语补足语a song。意思比较完整一点！he is sing a song.或者是he is sing songs.
5.你的爸爸昨天来看我。your father saw me yesterday.你这样翻译就成了你的爸爸昨天看见我了！
看可以理解成是看望或者是拜访。your father paid a visit to me yesterday.
6.his brother.拼写错误！、
7.他每天都努力工作（work hard）。 he work hard everyday.谓语动词应该用第三人称单数！
8.你的弟弟喜欢游泳。your brther enjoys swimming very much..
9.他过去是个好学生。he was a good student.还差一个状语成分！he was a good student in the past.

4. he go to school by bike everyday
5. he went to country by bike yesterday
8. your father came to me yeaterday
12. he is on the phone

先回答第三个he playing basketball yesterday 这是不正确的 句子结尾是昨天 前面动词必须是过去式 怎么还能用PAYING 呢 对吧
还有最后一个 这种表达方法也对 但是有个专门的词组表示过去曾经he used to be a good student 这就是我看了你翻译之后的想法 谢谢
