Accidents happen, but when they destroy the delicate balance of nature and cause the whole world to suffer, they become disasters, and we should do all we can to prevent them from happening again.
Bhopal chemical leak, December 1984, Bhopal, India
An explosion in the Union Carbide chemical plant in Bhopal, India, released a deadly gas called methyl (甲基) isocyanate(异氰盐酸), which is used to make pesticides. The gas formed a cloud that killed 2500 people; another 50000- 100000 people became ill. Trees and plants in the area became yellow and brittle. The explosion was caused by a mechanical failure that was not noticed in time to stop it.
Exxon Valdez oil spill, March 1989, Alaska, U.S.
On March 24, 1989, 11 million gallons of crude oil spilled into Prince William Sound from the tanker Exxon Valdez when its hull hit a reef and tore open. The oil, which is not yet cleaned up after billions of dollars have been spent and the millions of birds, fish, and other wildlife have died, was caused by human error and could have been avoided.
Chernobyl, April 1986, USSR
At 1:23 A.M. on Saturday, April 26, 1986, the reactor blew at nuclear power plant in Chernobyl, ripping open the core, blowing the roof off the building, starting more than 30 fires, and allowing radioactive material to leak into the air. Some 31 people were killed and 200 people were treated for radiation poisoning. Still at risk are 135000 people from the 179 villages within 20 miles, of the plant who were exposed to the radiation before being evacuated. Glaring violations of safety rules were at the bottom of this tragic event.
Love Canal, 1953, New York, U.S.
Love Canal, a small town in upstate New York near Niagara Falls, was destroyed by waste from chemical plants. Beginning in 1947, chemical companies could legally dump their waste products into the canal. The area developed a foul smell, trees lost their bark, and leaves fell throughout the year. A health survey found that the drinking water contained excessive levels of 82 industrial chemicals, 7 of which were thought to cause cancer. The people of Love Canal had an unusually high rate of cancer and birth defects. Eventually, many of the houses had to be abandoned. Today, the town has been partly cleaned up and some families have moved back to the area.
Three Mile Island, 1979, Pennsylvania, U.S.
On March 28, 1979, the worst accident in U.S. nuclear reactor history occurred at the Three Mile Island power station, near Harrisburg, Pennsylvania. No one was killed, and very little radioactivity was released into the air when coolant (the fluid that keeps a machine cool) escaped from the reactor core due to a combination of mechanical failure and human error. After 10 years and $ 1 billion in cleanup costs, the lower extremes of the reactor are still so radioactive that workers must use remote - control equipment to remove the remaining fragment of fuel core.

School violence is in the headlines again after recent shootings at schools in Pennsylvania, Wisconsin, and Colorado. After hearing the news, it’s natural for students — no matter how old they are or where they go to school — to worry about whether this type of incident may someday happen to them.
So how safe are schools? It’s actually safer to be in a school than in a car. Twice as many 15-to-19-year-olds die in car accidents than in shootings (and that’s all shootings, not just the ones that happen in schools). According to the Centers for Disease Control and Prevention, less than 1% of all homicides (杀人罪) among school-age children happen on school grounds or on the way to and from school. So the vast majority of students will never experience violence at school.
However, some schools have re-evaluated their safety needs in response to the concerns of families and communities. Some now require that guests check in at the office or have more guards on duty. Some schools have fixed metal detectors. Another thing that helps make schools safer is greater awareness of problems like bullying and discrimination. Many schools have practiced programs to fight these problems and to help teachers and administrators know more about protecting students from this type of violence.
The cause of school violence isn’t easy to understand. There is no single reason why students become violent. Some are just copying behavior they’ve seen at home, in the streets, or in video games, movies, or television. There’s one thing experts do agree on, though: Having access to guns or other weapons makes it easier for some people to lash out against the things or people they don’t like.
1.Which of the following statements can prove that schools are safe?
A.About 99% of 15- to-19-year-olds are safe at school. |
B.Fewer students have died in car accidents than in shootings. |
C.Students shot to death at school are half of all students. |
D.Fatal shootings of students are less than 1% of all homicides. |
2. After schools have re-evaluated their safety needs, ________.
A.families will be more concerned about schools |
B.communities will be responsible for schools |
C.teachers will pay more attention to shootings |
D.administrators will arrange to have more guards on duty |
3.From the last paragraph we can conclude that ______.
A.experts have found no reason for school violence |
B.students with weapons are easily upset about things |
C.school violence could be copied from violence in society |
D.no single reason makes students violent |
4.We could probably see this passage in ______.
A.an analysis report |
B.a realistic novel |
C.a case investigation |
D.a news journal |
