English sentences consist of a subject and a predicate. While many languages can omit a sentence subject, English very rarely allows this. Though you might write Responsible for analyzing data on a résumé, in most varieties of spoken and written English you must explicitly state the subject.

English even requires a kind of “dummy” subject to fill the subject position in certain kinds of sentences.

It is raining.

There is a strong wind.

Transitive verbs typically require that objects—and sometimes other information—also be explicitly stated. For example, it is not enough to tell someone Give! even if it is clear what is to be given to whom. You must say, for example, Give it to me or Give her the passport.
