1. In some cases, liaison is much necessary. E.g. acknowledgment-of-our-efforts, standing-up-for, this-is-a, mis-conduct, and-I. You need to speed up to complete liaisons fluently.
2. Inappropriate stress on a few preposition/auxiliary words or syllables that should not have a stress. E.g. "a"-ppreciate, "our" efforts. Also, the words that should be stressed is " honoured", thus less stress should be on "rec-ei-ve".
3. Some pronunciation of consonants can be more relaxed. E.g. "s", it should be difference from that in a Chinese character such as "si". "Ch" should sound different from as in "Q-ian" in Chinese.
