Normal Version

Small dogs live longer than large dogs. This is an exception to the general rule in the animal kingdom where larger species tend to live longer. The reason for this exception is due to human selective breeding practices that have made large dogs more susceptible to serious diseases. Large dogs have not had enough time to develop sufficient defense mechanisms for their size due to the rapid increase in their size through selective breeding. The study suggests that the increase in cancer among large dogs is due to a delay in their natural defenses.

Here are some tips for getting the most out of this site.


Beginners: My strategy is to first read the translation while listening to the audio. Then I listen to each sentence individually. After that, I practice saying the vocabulary words out loud. Finally, I listen to the whole text again without reading the translation. I don't try to remember or understand everything. I just let the language sink in as I gain more exposure. (Videos about Comprehensible Input)


Intermediate Learners: To gain some speaking practice, try opening the translation in your native language and then translate it back into the language you're learning. If you encounter any difficulties, you can refer to the transcripts.


Although you may use these lessons for short, intense study sessions, it's important for intermediate learners to engage in extensive listening and reading with simple books, TV shows, and podcasts as soon as possible.
