写作思路：根据题目要求，以我最喜欢的博物馆作为主题，比如以航空博物馆为例子，可以写明博物馆里面的特色，最后总结参观博物馆，学习到了什么，正文：
My favorite museum is the Aviation Museum.
我最喜欢的博物馆就是航空博物馆。
Because I have been to the Aviation Museum once, the scene that caught my eye most is the real big planes hanging from each other, and then going inside, there are all kinds of planes inside, including fighter planes, passenger planes and reconnaissance planes.
因为我去过一次航空博物馆，最映入我眼帘的一幕是一架架悬挂着的真实的大飞机，再往里走，里面的飞机各种各样，有战斗机、有客机、有侦察机。
What impressed me most was the astronauts who went forward bravely. They want to exercise and eat in weightlessness, in order to hold their own lives. How brave and noble they are in our hearts.
让我印象最深的是那一个个勇往直前的航天员。他们要在失重的状态下运动吃饭，来为持自已的生命，他们在我们的心中是多么的勇敢、多么的高尚。
On this day, I learned a lot about aviation. I want to study hard and be a brave and strong person like an astronaut.
这一天，使我学到了无比多的航空知识，我要好好学习像宇航员一样做一个勇敢、坚强的人。
