How to Research Paper Introduction

I've been reading a lot of ecological research papers for school this semester, and in addition to such papers becoming easier to understand, a few patterns are beginning to show themselves. Here's how to write an introduction for a research paper:

1. Find a topic in science

2. Based on that topic, write these two sentences with as few changes as possible: "Many studies have revealed this. Very few studies, however, have looked at this aspect of this."
     E.g. "Many studies have shown that people tend to sleep in beds. Very few studies, however, have looked at how bed type affects lifespan."

With an introduction like this and a lot of hard work, the data will essentially research themselves.
