    On November 12, 2017, the student in our class paid visit to China Science and Technology Museum.

    At 8:00, we left to China Science and Technology Museum by bus. At 8:30, a guide introduced it to us briefly and told us that what we should pay attention to during we visit. Ten minutes late, we began our visit. Some students took notes carefully as they visited. All the students were amazing at the rapidly achievements in science and technology. Three hours has gone by before we knew it. At 11:30, we returned to our school.

    This visit no only broadened my outlook but also aroused my interest in science and technology.
