              Summer is almost here, and the weather is heating up.   (1)  you drink enough water every day? Many kids don't, according to a new study   (2)   (publish) in the American Journal of Public Health.

              Erica Kenney, a   (3)   (science) at Harvard's T. H. Chan School of Public Health, originally planned to look into the amount of sugary drinks that kids were consuming in schools. However,   (4)    she was doing the research, she noticed that many kids were    (5)   (simple) not drinking enough water.

              Kenney and her team examined figures from a group of 4,000 children, ages from 6 to 19, between the years of 2009 and 2012. While looking through the survey results, she  (6)   (find) that more than half of the kids were dehydrated (脱水的).

              A lack   (7)  water can lead to health problems such as headaches, poor physical performance, and even more serious problems. Your body needs more water when you are in hot climates, when you are physically active, and when you have a fever.

              Kenney said,   (8)   is good news that this public health problem has a simple solution. If we can focus on encouraging kids   (9)   (drink) more water — a low cost, no sugary drinks — we can improve their drinking habits, which may allow many kids to feel  (10)   (great) throughout the day and do better in school."
