正：He went to the market, bought some flowers and then returned home.
误：He will go abroad after he finishes his high school education and studies there until he gets his doctor’s degree.
正：He will go abroad after he finishes his high school education and (will) study there until he gets his doctor’s degree.
（2）“呼应”的原则：在同一句话中或在同一段文段中，一般不能产生时态的“跳跃”，应形成一种呼应状态。
误：He said he has been there for three days and he will leave the next day.
正：He said he had been there for three days and he would leave the next day.
规则一：和一般过去时“呼应”的时态应该是过去完成时、过去将来时或过去进行时。
误：He has lived in this old house since he had been a child and he would move into a new house soon. He works in an office not far from his new house.
正：He has lived (has been living)in this old house since he was a child and he will move into a new house soon. He works in an office not far from his new house.
规则二：和现在完成（进行）时“呼应”的时态不应该是过去完成时或过去将来时，反之亦然。

May 3rd suny
It’s a lovely day today! The students of our school visited the Red Star farm.
In the morning, we get together at the gate of the No.1 Middle School, then full of happy, we were singing and laughing on our way to the farm.
We walked and arrived at the farm nearly at noon, there we received a warm welcome. After that, the farmers guided us to see many kinds of vegetables, telling us a lot of knowledge about those plants, asking us to taste some fresh fruites.In the middle of the day, we had a picnic on the farm, talking with each other. Then we held a small party, singing and dancing with the beautiful music.
Time also flies quickly, we had to say goodbye to the farmers. Twilight was falling as we returned to our school.
Night is coming, I am still excited about the visit today, washing to have a second chance to visit the farm again.
日记格式；suny应为Sunny
farm也应大写为Farm
记述过去，应为got

on our way 改为all the way更好



telling 与asking用得好



with 应为to

also多余


结尾较好。但有两处不妥：1.washing似为wishing之误 ；2.a second chance与 again意义重复。

参考范文
May 3 Sunday Fine
Today we visited a farm. Early in the morning we met at the school gate and went there together. The farm workers gave us a warm welcome. Then the head of the farm showed us around. How glad we were to see the crops and vegetables growing well! At noon we had a picnic lunch in the sun-shine. After a short rest, we had great fun singing and dancing, telling jokes or stories. Two of us even played a game of chess. The time passed quickly. Before we knew it, we had to say goodbye to the workers.
