WHAT time of day do you feel most clear-headed? Are you more of a morning person? Or does it take you a few hours to get your brain going? A lot of recent studies show that we should pay attention to our body clock. It can tell us at what time of day we are a1.to perform best, says the report.

When it comes to the human brain (大腦), many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you w2.up can help speed this up.

But everyone’s body clock is different and some have special patterns (模式). Morning people will get up early and work better early in the day. E3.people will get up later but their brain work better towards the end of the day.

Studies show that we are better at some activities at certain times of the day. Physical performance is at its best b4.3 p.m. and 6 p.m, so it’s better to exercise later in the day.

F5., it is best to eat during our active periods. This allows our body to burn calories better and stop our blood sugar levels (血糖水平) from getting too high.

Do you want to know something about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of the weather even further back.

It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would limit the growth of a tree. The change from a favorable to an unfavorable climate can be determined by reading the pattern of rings in a tree trunk. To find out the weather of ten years ago, count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.

Studying tree rings is important not only for the history of weather, but also for the history of man. In a region of New Mexico you can find only sand--no trees and no people. However, many centuries ago a large population lived there. They left suddenly. Why?

A scientist studied patterns of dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.

In this instance studying tree rings uncovered an exciting fact about the history of man.

1.It is understood that in a favorable climate____________.

A.tree rings grow close together

B.tree rings grow far apart

C.trees in New Mexico will grow big and tall

D.people can cut down most of the trees in New Mexico

2.Why did ancient people usually live where there were plenty of trees?

A.Trees provided them with shades.

D.Trees provided them with fruit and food.

3.Scientists are interested in studying tree rings because they can tell__________.

A.a lot about what happened in history.

B.whether a particular tree was healthy or not.

C.whether people took good care of the trees or not.

D.how old the trees were.

4.By studying the dead tree rings in Mexico the scientist found out____________.

A.where the people had to go

B.what the people had to eat

C.how the people left

D.why the people had to leave

5.The people had to leave the region of New Mexico because__________.
