B

Scientists found that our Earth is not cold, hard rock all the way through. Not at all. Only the crust, the outside of the earth is cold, solid rock.

Below this cold solid crust of the Earth, there is hot rock that melts in places. Every now and then some of the hot, melted rock is pushed out.

This hot, melted rock expands, and can push its way out through a weak spot in the Earth’s crust. When this happens, a volcano is made.

The melted rock below the Earth’s crust can flow, like toothpaste (牙膏), if it is squeezed. If you squeeze a partly filled tube of toothpaste in one place, what happens?

The toothpaste flows to another part of the tube. If you press down on one part of the tube with a finger, what happens? This tube rises in another place, as the toothpaste flows there, making a hill.

Strangely enough, when a volcano forms, the Earth may be behaving like a tube of toothpaste. If the Earth is pressed down in one place, it may rise in another place. Hot, melted rock within the Earth may flow to another place as the Earth is pressed down. When this hot, melted rock breaks through the Earth’s crust, a volcano forms.

A volcano is only one kind of mountain. Other kinds of mountains form when the Earth’s crust is raised. But each time the Earth is raised in one place, something is pressing against the Earth in another place.

E

New York State has passed the USA’s first state law banning motorists talking on hand-held cell phones(手机)．The ban will begin November 1，although drivers caught using hand-held cell phones will be given only warnings during the first month．

First-time violators(违法者)will face a ＄100fine．A second time call for a ＄200fine and every violation after that will cost＄500．

At least a dozen localities(地方)have established bans，starting in 1999；and 40 states have had bans proposed but not passed．At least 23 countries，including the Great Britain，Italy， Israel and Japan，ban drivers from using hand-held cell phones．

There are about 115 million cell phones in use in the United States and more than 6million in New York State．

“To think that I'm not going to use cell phone when at the same time I can still use my laptop(膝上电脑)，I still can read a paper，I can still change my pants(裤子)while driving 65 mph．I think there’s just something wrong，”an official said．

Other critics(批评)noted that other things like eating，drinking coffee and applying make up while driving posed(造成)at least as much of a concern(关注)．They suggested that the ban include a broader range of things．
