Just as mankind has always had a desire to fly, the human race has wanted to swim under the water since prehistoric times. Pictures of primitive devices to enable people to breathe underwater have been found dating from 3000 years ago, but our dream of moving freely beneath the ocean waves for long periods of time was only realized about 60 years ago, when French diving legend Jacques Cousteau developed the first practical Self Contained Underwater Breathing Apparatus(SCUBA). Since then the sport of SCUBA diving has gone from strength to strength.

Lovers of SCUBA diving like the feeling of weightlessness, the peace and quiet under the water, the ability to move in three dimensions and the sense of adventure they get while on a dive. SCUBA divers often travel to some of the most beautiful and remote places in the world in the search for rare underwater flora and fauna(動(dòng)、植物). Palau, The Red Sea, The Maldives and Hawaii have many of the most popular diving sites, but recreational divers often have to make do with less exotic local destinations, like the North Sea in Britain.

SCUBA diving is not without its dangers, however. The mixture of nitrogen and oxygen divers breathe underwater, combined with the pressure under the water can be deadly if a diver rises too quickly to the surface, causing a condition called ‘the bends’. Divers can also get lost or trapped when diving on wrecks, and fatalities(死亡)are particularly common in cave diving, where divers add to the dangers of diving by swimming through underground caves filled with water. Diving can also be harmful to the underwater environment. However with proper precautions diving can open up a whole new world, far from the stresses of daily life.

1. What is the writer trying to do in the text?

A. Advertise some popular diving sites.

B. Describe how to dive underwater.

C. Warn people against diving in the sea.

D. Give information about SCUBA diving.

2. What can the reader learn from the text?

A. There is uncertainty about SCUBA diving safety.

B. Divers have caused a lot of damage to the environment.

C. SCUBA diving is an old sport with a long history.

D. Divers always face the pressures in their life.

3. How might the writer describe SCUBA diving?

A. Interesting.   B. Relaxing.   C. Frightening        D. Unpleasant.

4. What do you think the author is most likely to suggest if he continues to write?

A. Getting out to dive underwater.   B. Stopping damaging environment.

C. Making better use of SCUBA.     D. Getting over the troubles of daily life.

Trouve sat up on its back legs arid growled（吼叫）the words “How are you, Grandmama?” The audience roared with laughter and clapped. Twenty-year-old Aleck gave the dog a morsel（一口）of food. His hard wok paid off. His dog could talk!
Aleck was fascinated with the different sounds of people’s speech. His father taught students who had a speech problem to improve their speech. Aleck paid close attention. Could an animal form sounds into words, too? He decided to experiment with Trouve, the family dog.
The easy part was teaching Trouve to growl whenever Aleck wanted. The little dog growled for a morsel of food.
Next Aleck moved the dog’s “l(fā)ips’ as it growled. It sounded like “ma ma ma.” Trouve learned quickly to stop the growling just as Aleck’s hand moved away. They practiced and practiced until the dog said “ma ma” perfectly.
Soon Aleck discovered more. If he pushed gently under the dog’s jawbone（下顎骨）, it made the “ga” sound. If he pushed once and moved the dog’s lips twice, he could make the dog say, “ga ma ma”. With even more practice, it sounded like “grandmama.” Whenever Trouve said “grandmam,” Aleck gave the god two treats, so Trouve loved the lessons.
Aleck tried to teach his dog to move its tongue. So that Trouve could say more words. That didn’t work, but Aleck didn’t give up.
After many hours of practice, Trouve could say, “Ow ah oo ga-ma-ma?” This sounded just like “How are you, Grandmama?”
Friends and neighbors traveled to see young Aleck and his amazing talking dog. Rumors spread that the dog could speak by itself, which wasn’t true. No matter how much Aleck tried, the dog was never able to move its lips without help.
Aleck’s full name was Alexander Graham Bell. He wanted to know more about the world all his life. He had many ideas. Some worked; others didn’t. But he kept trying—always learning; One of his inventions was something called the telephone.
