In academic English it is acceptable to begin a sentence with a subject gerund.

“Drinking and driving is dangerous” How

can you begin sentences with infinitives?

Why did you ask that question? A: Is there a way to satisfy my curiosity. E: I need to be clever/innovative!

Even the longer form using ‘in order to’ is not proper written academic English.

Why did you ask this question? C: To satisfy my curiosity. B: I want more freedom.

In other words, I would never begin a sentence with ‘to’ on a research paper that I planned on submitting to a college professor. In addition to that, my students are instructed not to

do so either.
