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 dark­or­light 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 light­colored rings are very wide，it means that the tree has been growing quickly that year.If the rings are narrow，it has been growing slowly.If the rings on a tree trunk were greatly magnified，you would be able to see why the rings are light­colored when the tree is growing quickly and dark­colored when the tree is growing slowly.The tree trunk is made up of microscopic tubes，like some pipes，carrying water from the soil，through the trunk，and up to the leaves.They are wide and thin­walled 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 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 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.

They go up and they go down. They take people from one floor of a building to the exact same spot on another floor. A new technology will break elevators free from their vertical (垂直的) prisons, allowing them to move side to side, at an angle (角度), even go outside into a city. German company Thyssenkrupp has developed a new kind of elevator that uses maglev (磁悬浮) technology to move elevator cabins. Called Multi, these elevators are no longer limited to a single vertical path.

A funny thing happens when elevators can go anywhere. Tall buildings, which are designed to work around elevators, can start taking on different shapes. They can go wide, add towers or go in unusual directions, and make room for green spaces that otherwise would have been an inconvenience. A single elevator can run from the east side of the first floor to the far west side of the 30th, no transferring or walking necessary. It gets even more interesting when an elevator leaves the building. Patrick Bass, Thyssenkrupp’s North America CEO, has worked in the elevator industry for 26 years. He thinks these elevators will create new transportation networks to support the cities of the future. As more people go into cities, there’s a renewed interest in creating energy efficient spaces. Moving people around quickly is a huge part of that.

He imagines Multi working perfectly with other Thyssenkrupp technology like the Accel moving walkway. Accel, which also uses maglev technology, speeds up after you step on and can go twice the speed of a regular moving walkway. It was the first use of maglev technology outside of a train. The Accel is already in use in some cities now.

1.Compared with traditional elevators, Multi can __________.

A.go more smoothly B.go in any directions

C.go up and down freely D.go directly from floor to floor

2.What will happen to buildings with Multi?

A.They will hold more people.

B.They will become much higher.

C.They will be in different shapes.

D.They will be connected to one another.

3.In what way can Multi support cities of the future?

A.They save space in cities.

B.They help avoid the rush hours.

C.They help people save money.

D.They help move people around quickly.

4.Why is the Accel mentioned in the last paragraph?

A.To show how Multi works.

B.To show the importance of the Accel.

C.To tell us other products by Thyssenkrupp.

D.To explain the wide use of maglev technology.
