The Dark Age of Greece
小題1:Among early civilizations, we call the low points "dark ages", because civilizations often dropped to such a low level that it is hard to get an accurate picture of their history during these periods. During a dark age, a civilization may not have produced monuments, statue, or other objects which we use to learn about early civilizations.
One' of the most important dark ages was the dark age of Greece,which lasted from about 1100 BC to 900 BC. Prior to-that-time,Greece had a highly advanced society called the Mycenaean civilization. The Mycenaeans were a trading civilization小題2:In fact, the Mycenaean civilization was so important that when it collapsed in the 12th centuryBC,most other civilizations in the region collapsed as well.The next 200 years are like a blank page to  historians and we know very little about this period.小題3:The collapse of the Mycenaeans brought an end to writing in the area, and thus an end to the written records historians rely on.
The little that we know about this period has been learned from archaeology. It seems that civilization became much less advanced. The pottery from this period is much simpler and less artistic. This suggests that there was lack of wealthy people to buy higher quality products. 小題4:   This would suggest a large decrease in population, possibly due to a widespread lack of food and consequent starvation.
Sometime around 800 BC, the Greeks began to emerge from this dark age, most probably due to the influence of other civilizations. They had lost their early writing system, but began to use the writing system of the Phoenicians at this time.小題5:Over the next 300 years, their civilization continued to rise, and their dark age was forgotten.
A．Many civilizations undergo a series of high points and low points during their history.
B．Many early civilizations underwent dark ages, but Greece never recovered from its dark age.
C．They began constructing larger cities and trading with their neighbors again.
D．Another interesting point is that most of the large cities of earlier time periods appear to have been abandoned in favor of much smaller settlements.
E.Many pieces of evidence suggest that there was a huge increase in population during the dark age of Greece.
F.and they did much to spread their culture across the eastern Mediterranean.
G.One major reason for this is that writing basically stopped.

Rules on how to be a fit kid
Being fit is a way of saying a person eats well, gets a lot of physical exercise, and has a healthy weight.   小題1: If you’re a kid who wants to be fit, here are three rules to live by.
1. Eat a variety of foods.
You may have a favorite food, but the best choice is to eat a variety.  小題2:  Taste new foods and old ones you haven’t tried for a while. Some foods, such as green vegetables, are more pleasing the older you get. Shoot for at least five servings of fruits and vegetables a day--two fruits and three vegetables.
2.    小題3: 
What does it feel like to be full? When you’re eating, notice how your body feels and when your stomach feels comfortably full. Sometimes, people eat too much because they don’t notice when they need to stop eating.   小題4:  And over a period of time, overeating can lead to unhealthy weight gain.
3. Limit screen time.
What’s screen time? It’ s the amount of time you spend watching TV or DVDs, playing video games, and using the computer. The more time you spend on these sitting-down activities, the less time available for active stuff, like basketball, bike riding and swimming.   小題5:

A．Drink water and milk.
