Question
Read the article about Maglev trains. What is unusual about this kind of train? Does the writer think this will soon become a popular form of transport? Why/Why not?
Answer
It is unusual because it has no wheels. It uses powerful magnetic levitation to move and floats above the tracks. The writer thinks it may become popular in the future if somebody finds a cheaper and simpler way to build the tracks but at the moment it is very expensive.
