Even after centuries of exploration(探险), the ocean still holds its mysteries. Although we know more today about the world’s oceans and creatures living in them than ever before, every once in a while the sea brings up something so strange, so unexpected, that makes the world wonder what it could be.

Such was the case when the currents (水流) of the Mediterranean Ocean recently washed a 13-foot-long, smelly body onto the shores of the village of Villaricos in Andalusia, Spain. An early report in the Spanish publication Lavante described the strange, horned (带角的) body as what might seem like a big fish, but it was already in pieces. Locals joked that it was some kind of Loch Ness Monster.

The media jumped right on the creature, of course. Some sites called it a horned sea monster. The popular newspaper Boing Boing called it a dragon. Some people guessed that it might be an oarfish(皇带鱼), which is actually a rarely seen kind of big fish that can grow up to 55 feet long.

But now the experts have weighed in and we’re sorry to report that it’s not a dragon, a Loch Ness Monster, or even an oarfish. “That is actually a shark skeleton (骨架),” Professor Grubbs from Florida State University told NBC News. “The parts toward the back were confusing me, but those are the lower caudal fin (尾鳍) supports. The “horns” are the scapulocoracoids which support the pectoral fins(胸鳍).” Scapulocoracoids are backbones common to many animals.

So there we go, another mystery solved. Well, the ancient maps that once described areas of the ocean as places of dragons have yet to be proven true. But it’s good to know that the ocean still has a few surprises for us, even in cases where they’re just dead, smelly bodies.

1.The creature mentioned in the text _____.

A. was about 15 feet long with a horn

B. could probably grow up to 55 feet long

C. was already in pieces but it was still alive

D. was found on the shores of a village in Spain

2.What does the underlined word “it” in Paragraph 2 really refer to?

3.The third paragraph is mainly about _____.

D. Boing Boing’s opinion of the creature

4.The main purpose of the text is to _____.

Many Chinese have been greatly shocked by the traffic accident caused by the drunk driver Sun Weiming, who has killed five and injured some others in Chengdu, Sichuan. However, such a case is not rare.

Today, the traffic accidents may have been regarded as a social problem. The car has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral(道德的) rights of others. In fact, the enemies of society on wheels are rather harmless but just ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even far beyond carelessness that can be imagined.

Researchers have estimated that as many as 80 percent of all automobile accidents can be attributed to(归属于) the psychological condition of the driver. Emotional upsets can change drivers' reactions incorrectly, slow their judgment, and make them blind to the dangers that might otherwise be obvious. The experts warn that it is important for every driver to make a conscious effort to keep his/her emotions under control.

Yet the irresponsibility that accounts for much of the problem isn't only put upon drivers. Street walkers regularly ignore or break traffic regulations. They are blamed in most vehicle walker accidents, and many cyclists even believe that they are not subject（受…支配） to the basic rules of the road.

Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicles have been raised both at the point of manufacture and through regular road inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to make people believe that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things present a threat to those with whom they share the road.

1. Traffic accidents may be regarded as a social problem because ________.

A. auto driving has become dangerous and harmful in today's society

B. people usually pay no attention to law and morality when driving

C. they have caused serious psychological problems among drivers

D. the car has killed and disabled more people than any weapon in history

2. Who are NOT mentioned as being responsible for the road accidents?

A. Careless bicycle-riders.                  B. Careless people walking in the street.

C. Irresponsible auto drivers.              D. Irresponsible auto manufacturers.

3. Discussing solutions to traffic accidents, the author seems to be________.

A. doubtful and hopeless

B. angry and disappointed

C. objective (客观的) and concerned

D. anxious and annoyed
