我也想试着改一下。

Attched please find a copy of a news release entitled "ABC Plastic To Feature its Extrusion and Injection Molding Products at the NPE and ANTEC Shows."

This news release highlights the output extruder screw. As I know,this extruder screw is no longer a viable end product. Thus it should no longer be promoted. However this release has caused some confusions among our potential customers since three inquiry letters  have been sent to the Kansas City office. To be sure, I would like to confirm with you about the current status of this product. Please respond to my email as soon as you can.

Thanks a lot.
