There are nearly 400 different types of sharks, but only about 30 types have even been reported as attacking human beings.
The chances of being attacked by a shark are very small compared to other dangers. Many more people drown（溺死）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（后者的）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.
Don’t be frightened（受惊吓）by sharks as there is 30 times greater chance of being hit by lightning than being attacked by a shark.

A leading biologist has found the angels and fairies that sit at top of Christmas trees did not get there under their own power.
Prof Roger Wotton, from University College London, found that flight would be impossible for angels with arms and bird-like feathered wings.  
"Angels cannot take off and cannot use powered flight,” said Prof Wotton. “They would need to be exposed to very high wind velocities at take off - such high winds that they would be blown away."
Some the world’s most famous religious paintings and architecture make most Americans believe in angels.
The study found that 68 per cent of the 36,000 adults thought that angels and demons (魔鬼) were at work in the world.
According to the latest study, angels lack the powerful muscles which allow birds to beat their wings.
Prof Wotton’s paper explores why there are so many stories about angels. “Angels are very powerful religious icons for people with faith. Their similarity to humans adds to their power. At the same time, they have wings on them because they are more than human. They take messages to heaven and therefore have to fly.” said the academic.

There are about 80,000,000 mines*  under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50  people including many children were’ killed ‘or htirt each iay.  In 2003,  APOPO,  a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng rats to search for the mines.
The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp*  sense of smell.  The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana.  The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’  training, the rats were taken to a minefiel山  They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers*  that they smelt out’a mine.  Then the mine was cleared. It had  taken two ‘deminers  a day to clear a 200㎡ . minefield,  but with the help of two rats ‘they could finish it in two hours.
The rats and ~he deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
【小题1】 The APOPO trained the rats to search for     .

【小题2】 While training the rats, the trainers have to be

Sharks frighten most of us, but Daniel Weaver, a shark scientist, swims with them for a living! We asked him some questions about this unusual job.

So Daniel, what’s it like to be a shark scientist?

Well, it’s a great job. I often travel to faraway places like South Africa and Fiji to study sharks. On the other hand, a shark scientist sometimes does boring desk work, such as writing reports. Also, shark scientists don’t usually get paid a lot.

What qualities (品质) do you need to become a shark scientist?

Shark scientists need to be wise and strong. They enjoy working outdoors and they have to be cool and patient (耐心). They also have to be quite brave!

So do you think it’s a dangerous job?

Well, sharks have up to 15 rows of sharp teeth. However, sharks hardly attack (攻击) humans. There are over 350 kinds of sharks in the world and only about 10 are dangerous to us. In fact, dogs kill more people every year than sharks! Humans kill over 12 million sharks a year for food and sport!

How do you become a shark scientist?

A shark scientist usually studies Marine Science or Zoology at university. It’s also good to get some work experience in an aquarium (水族馆). In my opinion, I have the best job in the world!
