English Experimental Room

Why English is so difficult for Non-Natives？

This is an experimental room where I try to uncover the mysteries of English using mathematical tools.

Generally, English grammar explanations often show sentence examples of sufficient conditions, or other words, sentence examples of well-known usage.

In here, I try to explain the definition(or necessary and sufficient condition) of grammar rules using Visualization as much as possible.

For example, there are strict grammar rules about time-series events in English, but it's necessary to select an appropriate tense.

Get the true meaning of Simple Tense by Visualizations

The Simple Present doesn't simply mean Present, but covers the Past, Present, and Future.

However, Simple Past and Simple Future can be understood as they are.

To master Perfect Tense without Visualizations is impossible

It's appropriate to call "Present Perfect Tense" "Past and Present Linked Tense."

Similarly, it's appropriate to call "Past Perfect Tense" "Older and Newer Past Linked Tense."

Annotation : The older event is expressed in "Past Perfect Tense," and the newer event is expressed in "Past Simple Tense" in a complex sentence. If you use Past Perfect Tense in a simple sentence, it must have implicit meanings of these two tenses.

Also, Future Perfect Tense describes events in the small future that approach the great future as an end point.

Again, it's appropriate to call "Future Perfect Tense" "Start and End Future Linked Tense."

To summarize them, the essence of Perfect Tense is that it can express a story that involves multiple events in chronological order.

It must be common knowledge for Natives, but ESL does not have clear images about it, so I think I'll talk more again.
