鲨鱼英语短文

There are nearly 400 different types of sharks, but only about 30 types have ever been reported as attacking human beings. Most people know that the most dangerous shark is the great white shark, mainly because they have seen the movie 'Jaws'. However, there are still two other sharks which are fierce. They are the tiger shark and the bull shark. The chances of being attacked by a shark are very small compared to other dangers. Many more people drown in the ocean every year than are bitten by sharks. The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. There are three types of shark attacks. The main one is known as a 'hit and run'. The shark attacks because it thinks you are a fish, but when it tastes a human it decides not to eat you. The second type is called a 'bump and bite'. The shark bumps you to find out if you are fit to be eaten and then bites you if it thinks you are. The third type is called a 'sneak'. When attacking in this way, the shark waits for you to swim by and attacks you suddenly. The latter two types of attack are more likely to be deadly for humans. However, your chances of being attacked by a shark can be reduced if you follow the advice below. • Do not swim in the dark. Sharks can still see you but you cannot see them. • Do not swim if you are cut or if you have a fresh wound. Sharks can smell blood over a long distance. • Do not wear bright clothing or jewellery because sharks are attracted to colours and shiny objects. • Try and stay in groups, as sharks usually avoid large numbers of people. Recently, shark attacks have been increasing as water sports are becoming more popular. If a shark attacks you, try some of the following tips to help you. • Do not panic. • Hit the shark on the nose. • Stick your finger in the shark's eye. Don't be frightened by sharks as there is 30 times greater chance of being hit by lightning than being attacked by a shark.

shark-skin like swimsuit A new high-performance swimsuit, developed by mimicking the skin of sharks, will be worn by top athletes in Athens from this week. The revolutionary new fabric, developed by Speedo, is the result of four years of research and development that began with the study of shark skin at the Natural History Museum . The new swimsuit, called Fastskin FSII, increases a swimmer's speed by reducing passive drag through water by up to 4% more than the next best swimsuit. Research into shark skin texture and movement through water was carried out under the guidance of Natural History Museum fish expert Ollie Crimmen. Tiny 'teeth' cover the surface of a shark's skin and the shape and positioning of these 'teeth' vary across the body to manage the flow of water. With these findings Speedo created a full 'bodyskin' with different fabrics on different parts of the body and for the first time, male- and female-specific and stroke-specific swimsuits.

谁更危险？鲨鱼是一个警醒全世界游泳者和冲浪者的一个单词。许多人认为海里遍布着危险的鲨鱼，并以为鲨鱼都想攻击人类。但是大多数种类的鲨鱼从来不攻击人类。一共有超过350种不同的鲨鱼，只有4种对人类来说是非常危险的。他们是白指针鲨，老虎鲨，公牛鲨和白鳍鲨。鲨鱼以小鱼，海豹及别的海洋动物为食。他们通过看，听，闻来寻找食物。在水里它们的听力非常灵敏，也能在几百里以外地地方闻到食物的味道。鲨鱼有又大又锋利的牙齿。当它们找到动物去吃的时候，它们把食物撕扯粉碎。人们总是害怕鲨鱼。但是鲨鱼并不总攻击人类。全世界每年只有75起鲨鱼攻击人类的事件，只有10人被鲨鱼所杀。但是，每年，人类杀死数以百万计的鲨鱼。所以谁更危险呢？鲨鱼还是人类呢?

对不起，现在比较忙！还请原谅！

Others carry all the blunt force of a baseball bat. "Shark Tale," a computer-animated mob spoof ---- not incidentally featuring the voices of two men previously involved in a mob movie co-starring a baseball bat ---- goes for funny.The end result of a film made by some of the same people who brought us "Shrek" is a visually creative underwater escapade, often charming and amusing, but not supremely clever or all that heart-tugging. "Shark Tale" swims as a technically impressive entertainment, hip and supercool, but not totally engaging.The story is of Oscar, voiced by Will Smith, who is at the bottom of the food chain, working at the local whale wash. Oscar talks the talk but doesn't walk the walk, seeking fame and glamour but never choosing wisely in his attempts to find those things. If it wasn't for the well-meaning advice of co-worker Angie (Renee Zellweger), an angelfish who harbors a secret affection for Oscar, he would be even deeper into his go-nowhere approach.Things change thanks to happenstance. The mob-boss shark, Don Lino (Robert De Niro), runs things but has trouble getting his vegetarian son, Lenny (Jack Black), to display the toughness necessary to become a boss himself. When Oscar quite accidentally slays Don Lino's other son, Frankie, then takes undeserving credit for the kill, he becomes a hero and cultural superstar, acquiring the wealth and fame he always desired.Trouble comes when Oscar must then repeatedly prove he's the shark-slayer he claims. Along with the way, and with the help or interference of several other comical characters ---- voiced by Martin Scorsese, Angelina Jolie, Peter Falk, Katie Couric and other talents, Oscar learns the true meaning of self-respect."Shark Tale" is loaded with amiable gags and likable characters, and some juicy touches that end up very funny, such as when a squirming, squealing shrimp is pleading for his life to great comical effect. It also has a primary lesson of accepting yourself and who you are as its main teaching, along with sidebar issues about respect and playing fair.It all adds up to a reasonably amusing but not oh-wow experience, lacking the same look-at-that ingenuity as "Shrek," even if some of the small touches are very clever.The movie gives us a chance to hear old pals De Niro and Scorsese trading funny lines ---- many of them improvised ---- taking us back to their many collaborations, including "GoodFellas," referenced above.Smith is ready-made for the role, and other supporting voices fit just fine. Ultimately, "Shark Tale" is just that ---- fine ---- though nowhere close to a genre breakthrough. Instead, it's a mildly entertaining underwater escapade, a little too aware of itself and its hip intentions, but sometimes dazzling to observe. 有点多啊。。
