A meaningful trip
The teenagers in the pictures are from Hangzhou,the capital of Zhejiang Province.They are having a trip in Zhejiang University.The number of them is 50.The trip is only 5 days,but it's meaningful.With the help of the professors there,the teenagers can use the scientific machines to have some tests.These scientific tests are about the environment.From the tests,they learn how to protect the environment.The professors there also give them some lessons about the environment.
From their faces,we know that they like to know more about the environment.They also help the scientists to do many things during their trip.After the trip,they will come back to their schools and families;they will tell their teachers;classmates and families something about how to protect the environment.Now they are students.They are learing something from their teachers.But in the future,they may become teachers,they will teach more people around them.Do you think this trip is meaningful?
