Ladies and Gentlemen, Welcome to this electronics exhibition. Here you can find almost all of the 1 products about our company. Let's go to the hardware section first. Please follow me. The products on display in this section are 2for old people who wish to use a computer at home. Look at the keyboard; its big keys are 3easy to use by those whose eyesight is not good enough. Here, please take a close look at the mouse. It can fit 4 hands. Besides, it has a special sound effect. Listen, not only are the sounds 5but the two buttons give out different sounds. Now, I'll give you three minutes to try for yourselves. Then, we'll go to the software section.
