Here are some of the most common reasons why kids hate school—and strategies（对策） to put them back on the road to success.

One fear that keeps children from enjoying school is separation    36    . It most frequently occurs during times of family stress or    37    a child is about to enter a new school.   38   , parents can feed a child’s anxieties by the way they    39  . With younger kids, watch how you say    40    those first few days of school. A firm “Have a great day, and I’ll    41    you up at 2:30!” is more confidence-inspiring than “Don’t worry, I can be there in ten    42    if you need me.”

You can help your child    43    fearful situations—from speaking up in class to taking tests—by rehearsing（预演）at home. Teach your child to    44    thoughts such as “I’m going to give up” with “I can handle this.”

Without any    45   , some kids dislike school .This may be the    46    if your child is always alone, pretends    47    to avoid class outings or give away treasured possessions in an attempt to be    48   .

Often loneliness problems can be solved. A child may need to learn how to    49    others in the eye when he speaks, or how to talk    50    a whisper—or below a yell. You might teach a young child a few “friendship    51   ”, such as “My name’s Tom. What’s yours? Do you want to play games?”

“A lot of kids who are very lonely have never been told anything    52    about themselves,” says Miami    53   Matty Rodriguez-Walling. “If a lonely kid is   54    some area—computers, for example—I’ll often have other students work with him. That does    55   for self-respect and helps the lonely child make friends.”
