They are often called “the rainforests of the sea” because they are home to thousands of species of fish, plants and other creatures. Coral reefs cover less than 0.1% of the ocean floor, but they support more than 25% of all marine species.Coral reefs are not just rocks. They are made up of tiny living creatures called coral polyps. These polyps live in groups and secrete a hard substance that forms the structure of the reef. Coral reefs grow very slowly—only about 1 to 2 centimeters per year. Some coral reefs have been around for millions of years.However, coral reefs are in great danger now. Climate change is causing the ocean temperature to rise, which makes the coral turn white and die. Pollution from factories and farms is also harming the reefs. Plastic waste in the ocean can get stuck on the reefs and kill the polyps. In addition, overfishing is destroying the balance of the marine ecosystem.But there is hope. Many organizations and individuals are working hard to protect coral reefs. Scientists are researching ways to help coral reefs adapt to climate change. Volunteers are cleaning up plastic waste from the ocean. Governments are making laws to stop overfishing and pollution.We can also do our part to protect coral reefs. For example, we can reduce our carbon footprint by saving energy and using public transport. We can also avoid buying products that harm coral reefs, such as certain sunscreens. Every small action can help save these beautiful natural wonders.4．What does the underlined word “secrete” mean in Chinese?A．吸收B．分泌C．消耗D．储存5．Which of the following is NOT a threat to coral reefs?A．Rising ocean temperatures.B．Plastic pollution.C．Overfishing.D．Marine protected areas.6．What can we infer from the passage?A．Coral reefs grow very quickly.B．Only scientists can protect coral reefs.C．If we take action, coral reefs can be saved.D．Coral reefs are not important for the marine ecosystem.7．What is the main idea of the passage?A．Coral reefs are home to many marine species.B．Coral reefs are in danger and need protection.C．How coral reefs are formed.D．Why coral reefs are important.CRoald Amundsen was the first explorer to reach the South Pole (南极). Born on July 16, 1872 in Norway, Roald grew up with his three older brothers. His father, a businessman in the shipping industry, died when he was just 14. Roald had dreamed of becoming an explorer, but his mother wanted him to become a doctor. He followed his mother’s wish until she died when he was 21. Then Roald left school to go after his dream of exploring. His adventure (冒险) on a Belgian research ship in 1896 was his first real polar exploration. When the ship got stuck in ice, the people on board were forced to spend the winter in terrible conditions. But Roald used his skills to find fresh food, and showed himself to be an able explorer. This was perhaps one of the most important experiences that would lead to him becoming an Arctic (北极的) explorer. Roald had planned to be the first man to reach and explore the North Pole. However, hearing that Robert Peary had already reached there, Roald changed the plan and decided to go to the South Pole. In January, 1911, Roald’s ship arrived at the Bay of Whales in Antarctica. His team set up camp there and prepared for the trip to the South Pole. The team set out to reach the South Pole months later. At first, they traveled quickly, but soon they had to pass over mountains and avoid dangerous places. Finally, after nearly two months of hard traveling, on December 14, 1911, they reached the South Pole. The exploration took 99 days and the team traveled over 1,800 miles to the pole and back.8．What can we know about Roald from Paragraph 2?A．He enjoyed his life in the Arctic very much.B．He was better at scientific research than others.C．He had already learned some skills to explore.D．He realized his dream of exploring the North Pole in 1896.9．Which picture shows the change of the speed on their way to the South Pole?A． B．C． D． 10．What can we learn from the last paragraph?A．Some members lost their lives during the trip.B．Roald was the first man to explore the North Pole.C．Roald’s ship arrived at the South Pole in January, 1911.D．They stayed at the Bay of Whales for months before setting out.五、单词拼写。(本大题共10小题，每小题1分，共10分)1.
