shot and killed 12 other students and a teacher before taking their own lives.The massacre was the largest in the history of this nation.This type of crime didn't exist 10 years ago.
Americans should stop acting surprised that these shooting happen in "nicer" neighborhoods.That's the only place they happen.None of the recent school massacres took place at an inner-city campus; they all occurred in smaller towns or suburbs.These killers haven't been from impoverished or extremely violent families.They don't appear to have been picked on(挨骂受罚) any worse than kids have been for generations.They chose alienation and destruction,and they found the tools to carry out their hate-filled plan.
Do not blame schools for these massacres.Schools simply take what they are sent.Question the killers' parents.The parents are supposed to teach their children respect and empathy for others' lives.Parents should help their offspring learn to handle taunt or conflict without resorting to violence.
All concerned adults should take a youth's threat to shoot someone as seriously as airport security guards take jokes about bombs.Students must be encouraged to tell teachers if a classmate threatens or jokes about violence.Administrators at schools around the country need to emphasize they will take such reports seriously,and that they will not identify any student who comes forward with such a report.
More gun regulations probably won't stop these shootings,but gun owners and sellers must take more responsibility for keeping weapons away from young people.Gun owners should keep their guns unloaded,locked up and hidden away.Most car owners don't leave their keys in the car even when they park in their own garage; gun owners should be at least as careful with weapons.
The federal government can't solve this problem.Schools alone can't solve it.More guns won't solve it.Americans must consciously create a culture that makes violence unacceptable.Parents need to stop allowing their children's minds to be polluted with violence.News media need to show more restraint and thought about how and what they report.
The Colorado massacre is a national tragedy.More's the pity if Americans do not stop,reflect and vow to make it the last school massacre.

The great majority of all earthquakes occur in two specific geographic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indians to the Atlas Mountains, including the Himalayas, Iran, Turkey, and the Alpine regions. It is in these two great belts or zones that ninety percent of all earthquakes take place; they may, however, happen anywhere at any time.
This element of the unknown has for centuries added greatly to the dread and horror surrounding earthquakes, but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior, patterns of movements in the earth‟s shell, variations in the earth‟s force of attraction, and the frequency with which minor earth shakes are observed, scientists have shown increasing success in expecting when and where earthquakes will strike. As a result, a worldwide earthquake warning network is already in operation and has helped to prepare for (and thus lessen) the vast destruction that might otherwise have been totally unexpected.
It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether, but as how and why earthquakes happen become better
understood, man will become more and more able to deal with their possible damage before they occur.
1.Which of the following statements is true according to the passage?
A. Earthquake destruction is declining
B. Earthquake forecast is improving
C. Man is no longer fearful of earthquakes.
D. Man is capable of conquering earthquakes
2.We can infer from the passage that quakes __________.
A. may happen anywhere at any time
B. mostly strike in oceans and mountains
C. are unobservable in masses of land
D. are hardly the direct cause of fatalities
3.The phrase “this element of the unknown” (Paragraph 3) refers to ___________.
A. the extension of earthquake zones
B. the percentage of earthquake occurrences
C. when and where earthquakes may occur
D. what big damage earthquakes may cause
4.Man‟s research on earthquake forecast at present is to ____________.
A. reduce the loss from earthquake disasters
B. lower the frequency of earthquakes
C. release the energy that causes earthquakes
D. analyze the relationship between different earthquakes
5. Which of the following describes the author‟s purpose in writing the passage?
A. Inform. the reader
B. Entertain the reader
C. Disprove a concept
D. Question a concept
The smallest bat in the world is from Southeast Asia.This kind of bat measures about 30 millimeters in length. The world's largest bat, the Giant Golden-Crowned Flying Fox, has a wingspan of 1.5 meters.Most bats eat insects,but many feed on fruit or nectar from flowers.
Many people think bats are blind,but this is not true.Many species have very good sight.Most bats communicate and find their way by making"echolocation" (回声定位法 ) noises.They produce high-frequency noises and can estimate the distance of an object by using the sound echoes that bounce back to them. So, while bats may travel in total darkness, they"see"using sound.
Sadly, bats are widely feared and misunderstood. Most bats come out of their shelters only at nightfall. Three bat species feed on blood. Because of these qualities, bats have long been linked in many cultures to death, darkness and blood-drinking.
Yet bats are important for agriculture and our environment. They help pollinate (授粉)plants and spread seeds. They also help control insects. Bats eat huge numbers of insects,including kinds that damage crops.
For example, a brown bat can eat more than 1,000 insects in one hour.Onereport says bats save American farmers billions of dollars every year by reducing crop damage and limiting the need for chemicals that kill insects.
Over one-fifth of all bat species are under threat. They face disease and the human destruction of their natural environments.In some areas, diseases have killed nearly 100% of bat populations.
