products本题问的是在展示会上参观者可以看到什么，根据文中"Here you can find almost all of the latest products of our company．”可知答案。

Ladies and Gentlemen:
    Welcome to this electronics exhibition. Here you can find almost all of the latest products of our company. Let’s go to the hardware section first. Please follow me. The products on display in this section are specially designed for old people who wish to use a computer at home. Look at the keyboard. Its big keys are particularly easy to use by those whose eyesight is not good enough. Here, please take a dose look at the mouse. It can fit all sizes of hands. Besides, it has a special sound effect. Listen, not only are the sounds pleasant, but 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.
