阅读表达。

     阅读下列短文并回答问题，然后将答案写到相应的位置上。

     [1] More than 40 million Americans move each year, but not always by choice. Whether you relocate

because of a new job or school for you or your spouse, for a lower cost of living, or for better

opportunities, adjusting to life in a new place can be scary and difficult-especially when you're not in love

with your new city. Here are some tips on how to make the most of your relocation and find happiness in

your new home.

     [2] Treat it as an adventure

Living in a new place is a great opportunity to experience new things and to grow as a person. So stay

positive, and get out there and explore! Sample the local cuisine. Visit landmarks and museums. Try local

activities that weren't available or popular in your former city, such as skiing if you came from a beach

town or surfing if you lived in the mountains. You may discover a talent or interest you never knew you

had.

     [3] Get involved

     Attend local events that interest you. Visit the weekly farmer's market or the neighborhood yard sale.

Volunteer. Take a class. Join a sports league. All of these things will help you meet people and feel

connected to your new town.

     [4] Locate the necessities

     Driving, riding, or walking around your new neighborhood is the best way to learn where everything

is. So head out and take note of the nearest supermarket, pharmacy, post office, library, etc.

     [5] Keep pieces of your old home

     To keep from getting too homesick, subscribe to your former city magazine or newspaper. Display

photos of or souvenirs from your favorite places in your old town. Hang decorations from your former

home. Just don't go overboard-hanging on to too much from your past will keep you from moving

forward and really enjoying your new home.

     [6] _________

     It takes time to get to know a new place, so don't expect to feel comfortable right away. Give yourself

time to adjust. To help the process and to meet new people, find a support group near you at Just Moved.org
