参考答案
I am an Engineer working for a large construction company in the city. To be more precise, I specialize in the building of railway bridges. When I am assigned a new bridge-building task, my colleague and I have to travel to the site, have a review of the surroundings, and then decide what type of bridge will be suitable. Lastly, we have to make recommendations to the railway company of all the alternatives, and give them some idea of the costs.
