1. We can change the position of adverbs like even, just, simply, only. It depends on where we want to focus our attention.

Even I understand this rule.
I even understood his speech.

2. We often put these adverbs before the verb and other people can understand when we mean from stress and intonation:

Рис. $$1$$. Question

3. The adverb ‘too’ can change its meaning according to position.

The tea is too hot to drink now.
The cake is freshly-made and the tea is hot, too.
Рис. $$2$$. Cake

4. We use ‘too’ at the end of an affirmative sentence to mean also.

Рис. $$3$$. Reading
Рис. $$4$$. Tennis
