How it works

What changes in the morning if you go to bed early? Follow the arrow: the action leads to the result below.
Use 「ことで」 to explain how a result is achieved. It means “by doing…” or “through…”.
「ことで」 can also explain a cause: what comes before it brings about the change or result that follows.
Verb dictionary form + ことで: for example, 「寝ることで」 and 「運動することで」.
This is more than “first do this, then do that”. 「ことで」 emphasizes that the first action brings about the result.

In this lesson, we practice using verbs. Nouns and similar words must first form a predicate; they cannot take 「ことで」 directly.

Although the results in the examples have already happened, 「減らす」 and 「運動する」 stay in dictionary form to describe the methods used.
