China's revised traffic regulations have stirred up controversy since it took effect on January 1st. They are believed to be the most stringent(严厉的) traffic regulations in the country.
According to the new rules, 52 different kinds of violations can result 48 penalties, up 49 38 under the previous regulation. And the new rule also doubled penalties 50 drivers face. In addition, drivers counterfeiting(伪造) the motor vehicle plates（车牌） 51 not installing one properly will have 12 points deducted immediately from the previous 6 points.
Many drivers say the punishment is quite heavy and they need to be more careful than before.
"If I run a red light twice, I will have to retake the traffic training course. I am very busy. I could lose my job for this. I can't afford to take the risk." some complain. But 52 voiced their worry about the yellow light rule. "I don't know whether I can stop if the light suddenly turns yellow. Plus, I think it will be better 53 the traffic lights are installed with countdown meters. If I know how much time is left I can decide whether 54 stop or not."
The new rule also stipulates(规定) that drivers with less than one year's driving experience cannot drive on expressways 55 .
阅读下列短文, 从所给的四个选项中, 选出最佳答案。
If you can find a tree which has been cut down, you will see many rings, or circles on the base of the trunk. By learning to read these rings, you can find out about the tree's life.
The number of rings tells you how old the tree is. Each year, new wood is formed on the outside of the tree. This new wood is light in color when the tree is growing in spring and summer, and dark in winter when the tree is not growing much. So, if you count the rings of dark-or-light-colored wood, you can often find out how old the tree is.
You can also tell which years have been good years and which years have been bad years. When the light-colored rings are very wide, it means that the tree has been growing quickly that year. If the light rings are narrow, it has been growing slowly. If the rings on a tree trunk were greatly magnified (放大), you would be able to see why the rings are light-colored when the tree is growing quickly, and dark-colored when the tree is growing slowly. The tree trunk is made up of microscopic tubes (毛细管), like some pipes, carrying water from the soil, through the trunk, and up to the leaves. They are wide and thin-walled when the tree is growing quickly and they are carrying a lot of water. They are narrow and stuck together when the tree is not growing so quickly.
When a tree is old, the tubes in the center of the tree don't carry water. The walls of the tubes have become thick with materials which have stuck along them over the years, forming a kind of wood called "heartwood". This kind of wood is darker in color than the young, growing wood on the outside of the tree.
You don't very often see whole tree trunks which have been cut across. But once you learn to read a cross section (横截面) of the wood, you can see much more in wood which has been used to make boxes, houses, and other things.
In most wood, instead of seeing the trunk cut across, you are seeing it cut along its length. Because you don't see the whole tree, you can't tell how old it is.
(1) The writer says you can tell the age of a tree by _______.
[ ]
A. the number of rings in its trunk
B. the size of the base of its trunk
C. the color of its rings
D. the rings on the outside of the tree
(2) When wood of a tree is mostly light in color, this means that the tree _______.
[ ]
A. grew slowly
B. grew quickly
C. only grew in winter D. only grew in summer
(3) If all the rings in the cross section of a tree trunk are wide and about the same width, then we can tell that the tree _____.
[ ]
A. grew quickly all its life
B. grew slowly all its life
C. grew quickly when it was young and more slowly later
D. grew slowly when it was young and more quickly later
(4) In a certain country, it is usually dry and rains heavily every three years. Which drawing given below shows a tree trunk from this country?

阅读下面短文，从每题所给的四个选项中选出最佳答案.
If you can find a tree which has been cut down, you will see many rings, or circles, on the base of the trunk（树干基部）. By learning to read these rings you can find out the tree's life.
The number of rings tells you how old the tree is. Each year, new wood is formed on the outside of the tree. This new wood is light in colour when the tree is growing in spring and summer, and dark in winter when the tree is not growing much. So, if you count the rings in dark-or-light-coloured wood, you can often find out how old the tree is.
You can also tell which years have been good years and which years have been bad years. When the light-coloured rings are very wide, it means that the tree has been growing quickly that year. If the light rings are narrow, it has been growing slowly. If the rings on a tree trunk were greatly magnified（放大）, you would be able to see why the rings are light-coloured when the tree is growing quickly, and dark-coloured when the tree is growing slowly. The tree trunk is made up microscopic tubes（毛细管）, like long pipes, carrying water from the soil, through the trunk, and up to the leaves. They are wide and thin-walled when the tree is growing quickly and they are carrying a lot of water. They are narrow and stuck together when the tree is not growing so quickly.
When a tree is old, the tubes in the centre of the tree don't carry water. The walls of the tubes have become thick with materials which have stuck along them over the years, forming a kind of wood called “heartwood”. This kind of wood is darker in colour than the young, growing wood on the outside of the tree.
You don't very often see whole tree trucks which have been cut across. But once you learn to read a cross section（横断面）of the wood, you can see much more in wood which had been used to make boxes, houses, and other things.
In most wood, instead of seeing the trunk cut across, you are seeing it cut along its length. Because you don't see the whole tree, you can't tell how old it was.
