阅读下面的短文，并根据文章后的题目要求回答1-5小题。

     (1)While adults need to eat breakfast each day to perform their best, kids need it even more. Their

growing bodies and developing brain rely heavily on the regular intake of food. When kids skip breakfast,

they can end up going for as long as eighteen hours without food. This period of semi-starvation can create

a lot of physical, intellectual, and behavioral problems for them.

     (2)If you and your kids regularly skip breakfast to save time or to get a few more minutes of sleep,

remember that eating a healthy morning meal will probably save your time in the long run. By recharging

your brain and your body, you'll be more efficient in just about everything you do.

     (3)Interestingly, studies show that kids who skip breakfast are late for and absent from school more

often than children who eat breakfast on a regular basis. Time invested in breakfast is much more valuable

than the few extra minutes of sleep you might get by skipping the morning meal. If you and your kids seem

unable to make time for breakfast, consider enrolling your children in a school breakfast program. If possible,

pack a breakfast brown-bag the night before so that you and your kids can eat on the way to school and

work.

     (4)Some people skip breakfast in an effort to lose weight, but actually it is more likely to cause weight

gain rather than weight loss. Skipping breakfast is strongly linked to the development of obesity. According

to research, skipping meals, especially breakfast, can actually make weight control ________. Breakfast

skippers tend to eat more food than usual at the next meal or eat high-calorie snacks to get rid of hunger.

      (5)To teens, especially teenage girls, skipping breakfast may seem like a perfect way to lose weight.

It's important for moms to educate their kids about the importance of the morning meal and role it plays

in maintaining good health and preventing obesity.
