Dolphins(海豚)are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this, they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time―at least twenty or thirty years. Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.
Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.
There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area-except for The Penguin.
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

Top lists are lecturing people on everything from “100 places to visit” to “100 books to read ”.
Aren't you just tired of being told what to do with your time?
Now you have a list to end all lists!
Take a look at the following two examples from the list of “101 things not to do”:
Swim with Dolphins(海豚)?
Swimming with dolphins is one of the world’s most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming and pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded with tourists, they could get caught up in ropes and killed by propellers(螺旋槳).
Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening their mouths.
Go to See the Mona Lisa?
There must be something about the mysterious(神秘的)smile. The 6 million people who visit the lady in the Louvre every year can’t all be wrong, after all. But they can be quite annoying, standing in front of you, holding up their cameras to prevent you from seeing anything. In fact, it is hard for you to see the painting clearly because you have to stay away from it for security reasons. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds at most.
If the mysterious lady in the picture knew her fate, she wouldn’t just be smiling, she’d be laughing.
So, still long to see the Mona Lisa? If you want to find out more about the list, read 101 Things NOT to Do Before You Die. Visit www.not2dobeforeidie.co.uk and buy the book at a 20% discount.
【小題1】According to the passage, swimming with dolphins________.

A.is the world’s most popular tourist activity
B.gives fun to both tourists and dolphins
C.will make tourists busy and tired
D.can cause danger to dolphins
【小題2】What does the author think about going to see the Mona Lisa?
A.It is wrong to go and see the mysterious smile.
B.It is not as satisfying as expected.
C.Fifteen seconds in front of the painting is enough.
D.Queuing for hours is worthwhile.
【小題3】The list of “101 things not to do” is made most probably because its author_______.
A.thinks it boring to do the things suggested by other lists
B.believes other lists are not humorous enough
C.intends to persuade people to read more lists
D.wants to provide a list different from other lists
【小題4】What is the main purpose of the passage?
A.To advertise a book
B.To introduce a website
C.To comment on popular lists
D.To recommend tourist activities.
