Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body.

Our bodies use varying（不同程度的） amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food.

In-line skating（滚轴溜冰）is a fun sport that everyone can enjoy. Follow these safety tips to keep skating safe and fun.
Step 1: Gear up!
Even before you put on your skates, put on all your safety gear（护具）.
Step 2: Buckle up!
Strap（绑紧）on your skates. Make sure they fit well and are snugly（紧贴）around your ankles. This helps your ankles stay strong and straight.
Step 3: Fall down!
You probably do not usually try to fall. But it is good to practice falling on skates. Fall forward onto your knee pads. Put out your hands and let your wrist guards hit the ground. See? Are you surprised that it doesn’t hurt?
Practice falling until it is easy to fall forward and get up again. If you are not afraid to fall, you will try new things. Knowing how to fall will help you be a better skater and find your balance. When you can stay balanced, you won’t fall as much.
Step 4: Stop!
Make sure you can stop on your skates. The quickest and safest is probably the brake stop. The brake is usually on the back of the right skate.
The brake stop:
Roll forward with your skates pointing the same way. Let your right skate roll a little forward. Bend your knees as if you are sitting down. Then press your right heel down hard. This will make your brake pad drag on the ground until you stop.
The T stop:
Roll forward with your skates pointing the same way. Then turn your right foot out so the toes are pointing to your right. Drag your right skate. Let the wheels drag on the ground until you come to a stop.
Another way to stop is to run or jump onto the grass.
Step 5: Roll around!
Find a flat, smooth place to practice. Do not skate in streets. Parks and playgrounds are good places to practice. Look for “No skating” signs to make sure you can skate there.

In Greek mythology（神话）, the gods punished Sisyphus by forcing him to roll a rock up a steep hill for eternity（来世）. But he was probably better off than if they’d forced him to sit and stare into space until the end of time, conclude the authors of a new study on keeping busy. They found that people who have something to do, even something pointless, are happier than people who sit around.
“The general phenomenon I’m interested in is why people are too busy doing what they are doing in modern society,” says Christopher K. Hsee, of the University of Chicago. “People are running around, working hard, the way beyond the basic level.” Sure, there are reasons, like making a living, earning money, and so on. But, Hsee says, “I think there’s something deeper: We have extra energy and we want to avoid idleness.”
In a study 98 students were asked to complete two surveys. After they had completed the first they were made to wait 15 minutes to receive the next one. They were given a choice of either handing in the first survey nearby or at a more distant location they had to walk to. Whichever option they chose, they received a chocolate bar. Not everyone chose to go to the faraway location. Two-thirds chose the lazy option. Yet those who chose to stay busy by going to the faraway location were found to be happier than those who had stayed put.
But if the chocolate bars offered at the  two locations were different, they were more likely to choose the far location—because they could make up a good and acceptable reason for the trip, Hsee and his colleagues say.
Hsee thinks it may be possible to use this principle—people like being busy, and they like being able to show being busy right or reasonable—to benefit society. “If we can find a way for idle people to engage in activity that is at least not harmful, I think it is better than destructive business,” he says. Hsee himself has been known to  give a research assistant a useless task when he doesn’t have anything to do, so he isn’t sitting around the office getting bored and depressed.
