填空题

Have you had a headache during a test Have you ever been so worried about something that you have a headache or even can’t sleep at night If so, then you know what stress is. Stress is what you feel when you are worried about something. This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid—all of which can give you a stomachache or a headache.
However, there are different kinds of stress. Some kinds of stress are good and others are bad. Good stress might happen when you’re called to answer questions in class or when you have to give a speech. This kind of stress can help you to get things better done. For example, you may do a better job on your test if the stress pushes you to prepare better before the test.
On the other hand, bad stress can happen if stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you’re having problems at school, or if anything else makes you unhappy every day. That kind of stress isn’t going to help you. And it can actually make you sick.
The best way to fight stress is to have a balanced life. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure(休闲), and Food. If you get enough sleep and eat properly, and if you exercise and leave time for fun, you’ll probably feel less stressed.

President Barack Obama had a big pat on the back for his young daughters on Tuesday, saying they have got used to life in the White House.

After more than a year at the US presidential mansion, Malia Obama, 11, and Sasha Obama, 8, have made their dad proud with their ability to balance their private life with life in the public eye, he told NBC television.

"The happiest thing about the past year and a half has been the girls' adjustment (适应). They have just been great. They're doing well in school," Obama said.

"They're not as constrained. They can wander around. Their Secret Service protection is a lot more low key (低调)," he explained. "So they've got soccer, they've got basketball, they go sleep over at their friend's houses.

"Sometimes I've got 12 little girls screaming on the third floor of the White House. And they made a great adjustment."

The president also admitted he was concerned about how his daughters would deal with his public life as they get a bit older.

"Now I get a little worried about them when they're teenagers because I think that's the time when you're already feeling uncomfortable about your parents, and then imagine if your dad's in the newspaper every day and people are calling him a fool. I feel a little worried about that."

"But on the other hand, Malia and Sasha have just turned out to be unbelievably well adjusted kids," Obama said.

"The thing that's most important to me is that they are so respectful of everybody and haven't gotten on any airs (摆架子). It’s all because of Michelle as she wouldn't put up with (容忍) any of that stuff."
