Of all the websites, one that has attracted attention recently is myspace．corn．Most of this attention has come from the media and tells every reason why the website should be shut down．The threat of internet predators （掠夺者） is indeed a tough reality, but shutting down the site is not the answer．If myspace．corn．were shut down, another site would quickly take its place．Therefore, the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them．
The key to staying safe on the Internet is to make sure that your profile （个人资料）is secure．The simplest way is to change the privacy setting on your profile to "private", which protects your information so that only the people on your friend list can view it．Although this is effective , it is not perfect．Predators can find ways to view your profile if they really want to, whether through hacking in or figuring out their way onto your friend list．Thus, you should never post too much personal information．Some people actually post their home and school addresses, date of birth, and other personal information, often letting predators know exactly where they will be and when．The safest information is your first name and province．Anything more is basically inviting a predator into your life．
Another big issue is photos．I suggest completely skipping photos and never posting a photo of a friend online without asking permission．
Most importantly, never, under any circumstances, agree to a real - life meeting with anyone you meet online．No matter how well you think you know this person, there are no guarantees that they have told the truth．But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are．Hopefully, the next time you edit your profile, you' 11 be more informed about the dangers of Internet predators and take the steps to defend yourself．

Everyone has heard of the San Andreas fault （断层）, which constantly threatens California and the West Coast with earthquakes．But how many people know about the equally serious New Madrid fault in Missouri?
Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River．Property damage was severe．Buildings in the area were almost destroyed．Whole forests fell at once, and huge cracks opened in the ground, releasing some strong smell chemicals．
The Mississippi River itself completely changed character, developing sudden rapids and whirlpools （激流和旋涡）. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards．Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811 ; but the severity of the earthquakes is shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast．Buildings shook in New York City, and clocks were stopped in Washington, D．C．
Scientists now know that America' s two major faults are essentially different．The San Andreas is a horizontal （水平的）boundary between two major land masses that are slowly moving in opposite directions．California earthquakes result when the two masses make a suddenly move．
The New Madrid fault, on the other hand, is a vertical fault; at some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface．Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks．
Even now, the rock continues to settle downwards, and sudden sinking motions cause earthquakes in the region．The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois．
Scientists who have studied the New Madrid fault say there have been lots of smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but the scientists say they have no method of predicting when a large earthquake will occur．
1.This passage is mainly about _____．
A．the New Madrid fault B．the San Andreas
C．the causes of faults D．current scientific knowledge about faults
2.Which of the following pictures best describes the type of the New Madrid fault?
3.This passage implies that ______．
A．horizontal faults are more dangerous than vertical faults
B．vertical faults are more dangerous than horizontal faults
C．more people would die if the 1811 New Madrid earthquakes happened today
D．the volcanoes that caused the New Madrid fault are still alive．
4.The underlined word "vertical" most probably means ______．
A．moving straight up B．terribly changing
C．breaking suddenly D．extending largely
A Train Floating On Air
A train that floats on air? It' s not magic — it' s magnets （磁）．And it' s close to reality．
In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus．In Japan, a whisper - quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power．And in China, a magnet train line linked Shanghai with nearby Pudong Airport．
These trains use magnetic levitation （悬浮）technology, "maglev" for short．They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles repel each other．
How does it work?
Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet - filled guiding way．With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past．
When an electrical current is sent through the track, the train moves．Turn the current backwards and the train slows down．
Maglev doesn't rely on the friction （摩擦力）of wheels on track, so it can climb a much steeper hill than a traditional train．And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop．
1.This passage is about ．
A．maglev B．magnets C．levitation D．electricity
2.Which of the following is a repelling action?
A.→←
B.←→
C.↑↑
D.↓↓
3.What can we learn from the text?
A．A magnet - filled guiding way is formed inside a maglev train．
B．Instead of electricity, magnets are used as the power of a maglev．
C．Maglev trains can climb hills with the help of magnet wheels．
D．Electric currents decide the movements of a maglev train．
4.What is the difference between a maglev train and an ordinary train?
A．A maglev train can climb mountains without power while an ordinary one can' t．
B．A maglev train can travel in college campus while an ordinary train is not allowed．
C．Travelling without a track, a maglev train is safer and smoother than an ordinary one．
D．Floating on a track, a maglev train is faster, quieter than an ordinary railway train．
Years ago while lying in my hammock （吊床）and drinking JD from the bottle, I noticed my dog dragging something under the fence．Upon inspection, to my disappointment, I realized it was the next door neighbor' s 10 - year - old daughter' s rabbit．For years I had watched her come home from school and head straight out to its cage, free it and play with it in the yard．I knew that day would be no different and fearing for our dog, I had to think fast．
The rabbit was quite dirty, as if it had put up quite a struggle, so I washed it, combed it with the dog brush and blew it dry with the leaf blower．Upon finishing its grooming I jumped the fence and replaced it back in its cage hoping its death would be written off as "natural caused"．
Back to the hammock and JD．Within the hour the neighbor' s Volvo palled in as usual and out popped the little girl, and as usual she headed straight for the cage．Only this time she stopped about six feet away and screamed: " D - A - D - D – Y！！！"
Her father, panic stricken, stood looking at the cage．Being the good neighbor that I am, I rushed to fence and asked if there was anything I could do．
Her father less than calmly shouted, "What kind of sick individual would dig up a little girl's rabbit and put it back in its cage?"
1.The girl was shocked because _____．
A．the rabbit was killed by someone
