Panting for breath after reading

When I was studying in Form 1, my English teacher was Mr Ang Chek Ming. Through him, I learnt the intonation of English words. He was very forceful when he spoke. He encouraged us to listen to English news broadcast over the radio. I could not catch what the newsreader was reading at first. Later, I was able to follow the news. According to Mr Ang, if we really pronounce every word correctly, we will be panting for breath at the end of reading a long passage.

I tried what he had said and I was panting for breath after reading quite a long passage.
