1. tourists attraction：
Connected two nounfuls to expressed a new meaning,we can thought so: If a location will attracted tourists，this location certainly was named“tourists attraction”.

2. airplane:
This vocabulary has a special structure either：the former part is the operation-environment of the latter part,thus we could understood this vocabulary was narrate "flying plane at the air" since the first airplane’s shape just liked a “double layers plane”。

Type3.状语前缀➕动词➕人称（物主称）性质的后缀
example：refrigerator
The first part means"repeat、it's behavior was continue all along"; the middle part was the majority one and came from Latin language、it means“frozen”; the last one part means this vocabulary was just narrate a object/alived being/organism.

Type4：Combined a verb and a noun into a new nominal vocabulary.
Example: helicopter
The former part is a Greek vocabulary which means"circle/spin"; the latter part means"wing" or "aircraft"…thus this whole vocabulary has narrated a aircraft : it's normal operation only depanded the lift-energy which came from wing’s circle rapid…。
