    Have you used “um…” “like…” “you know…” in your speech? Catch words(口头禅) are unnecessary words used to fill up dead paces while you speak. Speaking too many catch words is like a bad habit that we are unaware of. While most people tend to ignore it in everyday conversation, in a formal speech or an interview, too many catch words can make even the best presentation look bad.____

    Stop when we are in doubt. Catch words are used more often when a person is unsure about the sentence to use next.____If you are lost or in doubt over what to say next, just stop speaking, take a long pause, breathe in , figure out what to say and start again.

    Speak consciously and slowly. If the speech is too long and you talk continuously without thinking, then you might also be pushing in a few catch words in between.

    ____It is best to memorize the tricky parts of the speech, like the introduction and the conclusion where a majority of the catch words are used.

____ Preparing for the speech is very important when trying to remove catch words. Make it a point to pause when there is a comma or give two pauses at the end of the sentence. If certain words in the speech need to be emphasized then underline them and practice them as they need to be said.

    Avoid catch words in conversations. Get a friend or your partner to help you out when rehearsing a conversation.____ Although it can be an unpleasant and often embarrassing process, but in the long run it helps in cutting down on catch words.

A. Practise your speech when you can.

B. Remember the saying that silence is golden.

C. Therefore we can find out best friends to guide us well.

D. Anytime you use a catch word, the friend can point it out.

E. So we should learn some ways to avoid speaking such words.

F. Structure the speech well to include as much information as is needed.

G. The mind is so busy trying to figure out what to say that there is a strong urge to speak such words.
