Activity: The Zippers

Now guys you could do this activity ready?
Well it's easy just try to find 3 sentenses in passive voice I'll write my 3.

1.-An early device superficially similar to the zipper, was patented in the United States by Elias Howe in 1851.

2.-The clasps were joined together by a string, which, when pulled taut, caused the clasps to be evenly spaced along the closure.

3.-Initial versions of the zipper were based on the "hook and eye" principle.

See that was very easy now it's you turn tell me if you found more.
See you.
Xoxo, Sandy.
