"Таксі - дорогий транспорт."
Translation:A taxi is an expensive means of transportation.
the last comment below is quite correct but when I offered "the taxi is an expensive form of transport" I got told I was wrong and it should be "The taxi is an expensive modes of transport." This is quite simply formally grammatically incorrect. It should be at least 'mode' (singular) not 'modes'. But 'mode' is a very formal word, the kind of word used by bureaucracies rather than commonly in daily speech - so 'form' is actually better: it means the same thing and is more street-friendly. But actually better again would be "taxis are an expensive form of transport" or best of all "taxis are expensive"
