二、阅读理解
Scientists in England are using two self-directed water vehicles to explore the animal and plant life of the Celtic Sea.
The Celtic Sea is a body of water off the southern coast of Ireland. The area is known for its unusual sea life. Scientists want to know why sea creatures are so attracted to this part of the Atlantic Ocean.
One of the research vehicles is powered by batteries(电池). It collects information for the National Oceanography Centre in Southampton, England, and the World Wildlife Fund. The vehicle's low energy requirements permit it to stay floating on water for up to 30 days. Reports of what it finds in the Celtic Sea are sent by satellite.
Stephen Woodward is an engineer who helped design the vehicle. He says the vehicle has equipment that can discover small organisms called zooplankton(浮游动物) and fish. He adds that other sensing devices measure water currents and other features of sea life. The vehicle also creates a map of the sea.
Another vehicle is powered by the sun and the wind. It can stay floating on water for months. The robotic vehicle sends information about the so-called biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activity.
Lavinia Suberg is one of the scientists studying the Celtic Sea. She says productive ocean areas, like the Celtic Sea, attract zooplankton. The zooplankton then attracts fish. She adds that areas with a large increase of fish often attract sea mammals and birds.
Using these robotic ocean vehicles greatly reduces the cost of exploring the seas with manned laboratories. Scientists can spend more time analysing the collected information. They say the research will give them a better understanding of the needs of the Celtic Sea for future management and protection.
1. Why do the British scientists explore the Celtic Sea
A. To study the geography of the sea.
B. To learn why the sea is rich in sea life.
C. To test their self-directed water vehicles.
D. To learn about the sea creatures in the sea.
2. According to the text, the water vehicles _____.
A. are controlled directly by humans
B. work depending on the map of the sea
C. can send the information back directly
D. can keep floating on water for a long time
3. According to Lavinia Suberg, the sea mammals and birds _____.
A. are afraid of living alone
B. mainly feed on zooplankton
C. like to live in warm ocean areas
D. are especially interested in fish
4. What is the last paragraph mainly about
A. The aim of sea exploration.
B. The cost of exploring the sea.
C. The importance of the water vehicles.
D. Ways to deal with the collected information.
Zheng He had over 200 ships, some of which were over 150 metres long and could carry up to 1, 000 people. In addition to the supplies for the long journeys, the ships carried gold, silver, silk, china and other treasures to give as gifts to the rulers of the neighbouring countries. Some of the ships even had earth on board so that the sailors could grow their own crops for food.
On Zheng He's first voyage, he set sail across the Indian Ocean. His fleet travelled for many days far away from land. One day, they were hit by a storm. All the sailors thought the fleet was going to sink. Then a strange light appeared at the top of the ships, masts, and after that, the storm passed. The strange light that appeared on the masts was probably electricity from the thunderstorm.
Many sailors today see such lightning on the masts of their ships during a storm. But the sailors in Zheng He's fleet believed it was a sign of protection from the ancestors. From then on, they were happy to follow Zheng He wherever he led them.
Zheng He completed seven famous voyages between 1405 and 1433. He visited many countries in Asia and Africa. Zheng He also brought back many gifts from the countries he visited, such as medicines, pearls and strange animals. The most famous of these gifts were a giraffe and a zebra.
When Zheng He came back from his seventh voyage in 1433, he was sixty-two years old. In 28 years travelling, he had managed to share the glory of China with many different countries. When he died in 1433, the stories of his travels made him one of China's most famous sailors.
5. Zheng He was famous for _____.
A. his seven voyages B. his 200 ships
C. his crops grown on the ships D. the large amounts of treasures
6. What might not be found on Zheng He's ships
A. Food. B. Metal. C. Flowers. D. Earth.
7. Why were the sailors happy to follow Zheng He wherever he led them
A. Because Zheng He was a rich officer.
B. Because they thought they could be free from danger with Zheng He.
C. Because they thought they could travel around the world.
D. Because Zheng He's fleet never sank.
8. What's the most important achievement of Zheng He's voyages
A. He was very old when he finished his last voyage.
B. He set sail across the Indian Ocean.
C. He brought back many gifts from the countries he visited.
D. He promoted the communication between China and other countries.
