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.
