Comprehensive Samples
Sample 1

Thank you, Mr. Chairperson, Mr. Director-General, distinguished members of the ILO's Governing Body and friends. I welcome this opportunity to be here today, with an Organization which in many ways belongs to all of us workers. I can think of, in fact, no other international body that one can claim as one's own so unambiguously.

I have also had a longstanding formal association with the ILO. Many of my early pieces on women and technological change and on land rights were published by the ILO, as well as was the work of many other scholars. It is therefore a pleasure for me to be here on this important Symposium.

The canvas of the Symposium is very large. I will focus on two aspects of gender  inequality that centrally effect millions of women as workers but perhaps have failed to receive the attention they deserve. First, the gender gap in command over property and Productive assets and, second, gender biased social perceptions and social norms.

Sample 2

I learned last May that you have to be careful in speaking to a group of professional communicators. After I conducted a writer' s workshop at the Toronto Conference of the International Association of Business Communicators, Janine Lichaczwrote asked me to speak here tonight and used the communication techniques I had recommended. She even included a footnote citing my lecture. I am susceptible to good communication and to flattery so I am pleased to be with you to discuss your topic for the evening, the use of language in the art of speech writing.

I suppose we must begin by shaking our heads, woefully, over the sad state of language today, whether in formal speeches, casual conversation, or in writing. Most of us in this room no doubt agree with the generally negative tone of Time Magazine's year-end assessment which claims “our language has been besieged by vulgarities”. But to preserve our sanity as professionals in communication of us would probably join Time in optimistically expecting English somehow to   survive and even to prosper.

Expressions on Other Occasions
Correcting the Title of the Presentation

First of all, I would like to mention that the title of my presentation should be ...

Please allow me to correct a mistake in the title of my speech which appeared in the program. Instead of... it should read...

I'm going to read the paper by Dr. Wang. It's a great pity that, because of a health problem, he could not be here.

I was asked by the author to read his paper. He apologizes for not being able to come here.

The next speaker, Prof. Zhang, regrets that she could not be here and has submitted her paper to me. I am not sure if I can present it as well as she expected.

I am not sure whether I' 11 be able to be very confident in answering specific questions. However, I am somewhat familiar with his work, so I' 11 try my best.

Checking the Microphone
First I want to check if all of you can hear me clearly.

Am I speaking clearly and loudly enough for those in the rear of the room?

I wonder if those in the rear of the room can hear me.
