Visitors to London are struck by the proud splendour and glamour of one of the world's oldest capitals, admiring iconic sites like Big Ben, the Palace of Westminster and Buckingham Palace.

This vibrant market has been featured in a number of films, documentaries and bestselling books, the most famous being the film ''Notting Hill'' starring Hugh Grant and Julia Roberts, which brought Portobello Market to the attention of audiences all over the world.
Portobello Market is divided into different sections selling second-hand items, clothing, jewelry, souvenirs and vegetables. The most sought-after area is devoted to antiques. Visitors may feel overwhelmed as there are over 1,000 booths manned by antique dealers from throughout England. It's a great fun to browse through antique cameras, watches, pottery and paintings that date back 300 years. They are sold at different prices, so it's possible to find a few good bargains. It seems that both buyers and sellers look forward to the weekends when they can meet and escape the city's fast pace at Portobello Market.
When tired from exploring the market, visitors can drop into the nearby food courts to savour an Indian curry, Italian pizza or sandwiches from Europe. It's a great pleasure to drink a cappuccino while listening to street performers. These represent the lively fun of Portobello Market, offering exciting experiences that keep people coming back.

Dolphins are one of the most intelligent species on the planet, which makes them a very interesting animal to scientists. In their natural habitats, dolphins use various vocalization techniques. They whistle and squeak to recognize members of their pod, identify and protect their young, and call out warnings of danger. They also make clicking sounds used for echolocation to find food and obstacles in dark and murky waters.
Amazingly, the whistling sound that the bottlenose dolphin makes has been found to have a similar pattern to human language. They always make conversational sounds when they greet each other. If you listen to dolphins' squeaks and squeals, it will sound like they are having a conversation.
Dolphins usually use both sound and body language to communicate with each other. It is through gesture and body language, however, that most of their communication with humans comes. Dolphins can be trained to perform complicated tricks. This suggests they have a high level of intelligence and communication capacity. If they work for a long time with a trainer, they are able to recognize and understand human commands.
A lot of dolphin communication has been studied using dolphins in captive environments. These studies have been criticized because some marine biologists believe that dolphins living in aquariums or research centers cannot be considered "normal." Even so, most believe that studying dolphin communication in captivity is useful for beginning to understand the complexity of dolphin communication. After all, dolphins are one of the most intelligent animals. Their ability to communicate is impressive and worthy of study. 
According to paragraph 4, what do some marine biologists think about captive dolphins?
A.Their relationships are too personal with marine biologists. 
B.They can't be considered accurate subjects for biological studies. 
C.They can communicate exactly the same as humans do.
D.They easily demonstrate how dolphins act in the wild.
