Dear Li Ming,

    You have 2 a difficult but great job. Architecture is unusual because it is a mixture of both art and science. You need to be 3 to think of new and interesting designs(设计). You also need to be good at math and science so that you can translate your creative ideas into buildings that are safe and 4. Even language is important to an architect. You need to be able to express your ideas 5 so that other people can understand them.

He or she 9 a plan that shows all the details of how the building will be constructed(建造). The architect does not actually build the structure. But questions often come up during the construction, 10 the architect always needs to be found easily.

    11 the idea in my mind becomes a real building is my favorite. That is always12for me!

    Please let me know if you have any other questions. You are also welcome to visit me anytime.
