Dear Tom,
You asked me why I like living in New Mexico.I like it?21?it is so beautiful.We havemountains,mesas(平顶山),rivers,and forests.Mesa is the Spanish?22?for a broad,flat-toppedmountain.For 12 years,I have?23?across the state several times a month,and I still find newplaces that take my breath away.
24?else do I like about living in New Mexico?I like the sunshine.We have over 300?25?days a year,with deep blue skies.Because we are 7,000 feet above?26?level and the weather isvery dry,the air is very?27?and the nights here are much colder than the days.
The many days of sunshine are a very good thing for our state.Do you know that New Mexico?28?more than 3,200 hours of sunlight every year?With that much sunlight,we are one of thesunniest states in the United States.Some people?29?that if we could use the energy from all of thesunlight here,we could?30?more than enough power for the whole United States!
The weather in New Mexico is good for?31?energy out of sunlight,but sometimes the lack ofrain is a?32?for people living here.Most of the state is desert,and there isn't enough water?33?drinking,growing food,and other uses.Farming is very difficult here because of the water shortage(短缺).There are many laws about water use in New Mexico so that everybody uses just enough.The?34?for water increases as more and more new homes are built.
So,as with all places,there are things that are wonderful and yet others that are35aboutliving in New Mexico.How about you?Do you like living where you are?
Yours,
Anna
