PART THREE   READING  PREHENSION （共15小题；每小题 2分，满分30分）
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.
A
With school out and hot weather in, it’s not unusual for youngsters to gather around the refrigerator or the television rather than take part in active play. Such habits may be relaxing but can wreck a healthy lifestyle, say specialists at Texas Children’s Hospital.
“For some kids, the state of feeling bored triggers（引发）eating,” says Jennifer Thomas, a doctor at Texas Children’s Hospital in Houston, Texas. “A child can pick up 5 to 10 pounds over the course of a summer, so it’s important to recognize the difference between boredom（无聊）and hunger.”
Because children may be adjusting（适应）to lack of routine, adding some structure to their daily schedules can help. “For example, instead of letting kids eat while they watch television, permit eating only in the kitchen with the television turned off,” says Thomas. “This way can help determine if they are really hungry or just bored.”
If hunger causes a snack attack, nutritious snacks should be available（可得到的）and easy to reach, says Thomas. She suggests two or more servings of fruit and three or more servings of vegetables as a reasonable（合情理的）daily goal. Thomas says, “Fresh or frozen fruit is better than fruit juice. Fresh or frozen vegetables are better because canned vegetables usually contain salt.”
In general, kids should avoid snacks with high sugar content, says Thomas. “More importantly, if a sugary snack takes the place of healthier food, the child is not getting the nutrition he or she needs. High-fat food tends to make a child feel worried, while eating foods that are naturally lower in fat will make it easier for kids to feel more energetic and stay on the go.”
