If you are looking to putting a tree in your home for Christmas, there is always one debate that seems to arise in most households: whether you want a real tree or fake tree. Year after year, as we find ourselves cleaning old pine needles (松针) for months on end, we decide that we will never get another real tree. So that begs the question: Which kind of tree is better?

There is certainly a lot to be said for real trees. There is something fun about gathering the family together, going to a Christmas tree farm, and selecting or even cutting down your own tree. Real Christmas trees have that lovely holiday pine needle smell and they look great in your home.

Of course, on the other hand, they also leave a complete mess behind and needles that seem to keep appearing for weeks or even months after the tree comes down. You must also find a way to deal with your real Christmas tree after you’re done, which may mean cutting it into pieces so it will fit in the trash. Many dustmen will refuse to take away a tree that is left beside your regular trash, especially if it is a big tree or an old, yellow one with falling needles, making it hard to pick up. They don’t want a face full of sharp needles any more than you do!

With a fake Christmas tree, there is no mess, but there is also no Christmas smell and no exciting trip to the Christmas tree farm. Of course, these trees look the same in appearance as a real tree when decorated. Many of them come already with lights, so using that old, messy string of lights will be a thing of the past. For some people, a can of pine air freshener is enough to recreate the pleasant smell of a real tree.

As to which tree is the better choice, it is really a matter of personal preference. Both real and fake trees certainly have their benefits, and knowing which is better for you this Christmas really depends on what your family wants.

a.providing more fun

b.easy to clean up

c.giving off a natural smell

d.easy to decorate
