XIX. I. READING

Read the text below. Match choices (A—H) to (1—5). There are three choices you do not need to use.

MOVING

Most children will move at least once during their childhood. While moving can often bring adventure and excitement, it can also mean leaving the easy familiarity of home, school, and neighbourhood, and saying goodbye to cherished friends and schoolmates. Through a child's eyes, even a move of a short distance is likely to seem cross-continental. The following hints will help ease the transition.

1. ( ) If tempting to send your child off to grandma's while you attend to a million details, reconsider! Your youngster gains control over the scary unknown by participating directly in move-related activities. For example, have your child pack and label a box of favourite belongings to be opened immediately upon arrival.

2. ( ) Distance permitting, drive to your new home and neighbourhood a few times prior to relocating. Subscribe to a local newspaper. Call the Chamber of Commerce for pamphlets describing your new community. Start a scrapbook containing photographs of the new surroundings: home, backyard, child's room, school, and playground.

3. ( ) Encourage your child to write or send cards to old playmates. Arrange periodic calls or visits. Read books together on how other children have coped with moving. In addition, some moving companies offer related pamphlets and colouring books for children.

4. ( ) Acknowledge feelings of sadness and hesitation along with the positive ones. Ask what worries and also excites your child most about the move. Stress that it will take a while to adjust to the new surroundings and feel settled again. Emphasise the support and security of the family itself.

5. ( ) Befriend parents with children of your child's age. Join a family-oriented community centre. If your child is interested, organise or find a Scouts or campfire group. Search out music, sports, or dance opportunities. (This is especially good in the summer months when the ready-made activities of school are not yet available.) Above all, let your child observe you taking steps to become involved.

A Talk over family feelings about the move.

В Include your child in pleasant conversation.

C Involve your child in the move as much as possible.

D Familiarize your child with the community before you move.

E Once relocated, join the new neighbourhood.

F Use a notebook to write everything down.

G Retain some ties to the past.

H Maintain frequent physical contact with your child.
