高中英语人教版选修七Unit 3 Under the sea同步练习

阅读下列短文,从每题所给的四个选项 (A 、B 、C  和 D )中,选出最佳选项。

    The pillage (掠夺) and destruction of ancient shipwrecks and sunken archaeological sites by treasure hunters seeking gold and other valuables may be illegal under the terms of an international treaty under discussion by UNESCO's 188 Member States.

    "Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott.

    According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the world's oceans. Even the figures for the known wrecks are impressive. The Northern Shipwrecks Database for example contains 65,000 ship loss records for North America alone from 1500 AD to the present. The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12,542 sailing ships and war vessels lost between 1824 and 1962.

    Then there are sunken cities such as the trading town and pirate stronghold(海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692. Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah's great flood.

    These treasures of cultural heritage are under serious threat. Technology now allows extraordinary access to the ocean depths for determined and well-financed treasure hunters. And the potential rewards are huge. In 1985, American salvor Mel Fisher discovered the wreck of the Señora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US $400 million.

    An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings. We gain an enormous amount of information and knowledge from this work. With treasure hunters, all of this is lost. This is tragic, for humanity as a whole.

(1)、Why is it important and urgent to protect our underwater heritage?
A、Underwater heritage is easily accessible to treasure hunters. B、Underwater heritage is out of reach of archaeologists. C、New technology makes protection of underwater heritage easier. D、There is no law to protect underwater heritage.
(2)、What is the third paragraph mainly about?
A、Shipwrecks discovered by commercial salvors. B、The main cause of shipwrecks. C、The history of sunken ships. D、The figures of shipwrecks around the world.
(3)、What happened to Port Royal in 1692?
A、It was washed away by flood. B、It was beneath the waves after an earthquake. C、It was discovered under the Black Sea. D、It was rebuilt by Noah.
(4)、Why is Mel Fisher mentioned in the fifth paragraph?
A、He risked his life in treasure hunting. B、He was one of the most successful commercial salvors. C、He made a great discovery of shipwrecks. D、He had no trouble in finding a shipwreck.

    I still remember my first day at school in London and I was half-excited and half-frightened. On my way to school I wondered what sort of questions the other boys would ask me and practiced all the answers: “I am nine years old. I was born here but I haven't lived here since I was two. I was living in Farley. It's about thirty miles away. I came back to London two months ago.” I also wondered if it was the custom for boys to fight strangers like me, but I was tall for my age. I hoped they would decide not to risk it.

    No one took any notice of me before school. I stood in the center of the playground, expecting someone to say “hello”, but no one spoke to me. When a teacher called my name and told me where my classroom was, one or two boys looked at me but that was all.

    My teacher was called Mr. Jones. There were 42 boys in the class, so I didn't stand out there, either, until the first lesson of the afternoon. Mr. Jones was very fond of Charles Dickens and he had decided to read aloud to us from David Copperfield, but first he asked several boys if they knew Dickens' birthplace, but no one guessed right. A boy called Brian, the biggest in the class, said: “Timbuktu”, and Mr. Jones went red in the face. Then he asked me. I said: “Portsmouth”, and everyone stared at me because Mr. Jones said I was right. This didn't make me very popular, of course.

    “He thinks he's clever,” I heard Brian say.

    After that, we went out to the playground to play football. I was in Brian's team, and he obviously had Dickens in mind because he told me to go in goal. No one ever wanted to be the goalkeeper.

    “He's big enough and useless enough.” Brian said when someone asked him why he had chosen me.

    I suppose Mr. Jones, who served as the judge, remembered Dickens, too, because when the game was nearly over, Brian pushed one of the players on the other team, and he gave them a penalty (惩罚). As the boy kicked the ball to my right, I threw myself down instinctively (本能地) and saved it. All my team crowded round me. My bare knees were injured and bleeding. Brian took out a handkerchief and offered it to me.

    “Do you want to join my gang (帮派)?” he said. At the end of the day, I was no longer a stranger.

    From ancient stories to modern researches, the label(标签)attached to being left-handed is undeniable. Left-handed people, or "lefties" as they are often called, are generally believed to be good at art — Leonardo da Vinci, Picasso and Michelangelo are all left-handed.

    Our brain is divided into two parts: the left hemisphere(大脑半球)and the right hemisphere. The left hemisphere, linked to logic and analysis, is responsible for the right side of the body. The right hemisphere, linked to creativity and imagination, controls the left side of the body. So, people tend to believe lefties are controlled by the right side of the brain, and are more creative than right-handers. Some also think that lefties may not be as good as right-handers in mathematics and problem-solving skills.

    However; a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong. The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old. They were asked to complete several mathematical tasks of different levels. It turned out the left-handers outperformed the others when the tasks involved difficult problem-solving. This pattern was particularly clear in male adolescents. However; when it came to simple arithmetic, there was no difference between left-handers and right-handers.

    It was also discovered that those who are "severely" right-handed performed less well in all the experiments compared to "medium" right-handers and left-handers.

    "Taken together, these findings show that handedness does influence abilities to some degree," the study's authors wrote. However, "handedness is just an indirect expression of brain function," wrote psychology professor Giovanni Sala from the University of Liverpool in the UK, the lead author of the study. Sala also noted that only one third of people with a highly-developed right side of the brain are left-handed. It means that there are lots of right-handed people with a similar brain function as left-handers.
