问答题 Read the following passage quickly and don’t look back when you answer the questions numbered 1-8 later. The Hawaiian Islands If you would like to go to a beautiful, faraway place, you should go to the Hawaiian Islands. Located in the middle of the Pacific Ocean, these islands are far from any other land. They are, in fact, the farthest from land of any islands on earth—about 2,400 miles from San Francisco, 3,830 miles from Tokyo, and 5,540 miles from Hong Kong. There are eight Hawaiian Islands. In order of size, they are Hawaii (the "Big Island"), Maui, Oahu, Kauai, Molokai, Lanai, Niihau, and Kahoolawe. In 1959, the islands together became Hawaii, the 50th state of the United States. While they differ from one another in some ways, the islands share many of the same features. They all have a tropical climate, first of all. The average daytime tem¬perature is about 78 degrees Fahrenheit in the winter and 85 degrees Fahrenheit in the summer. However, it is never uncomfortably hot. The nighttime temperature is always cooler and there is generally a little wind. Rain falls often, but usually not for long. People in Hawaii say that it rains every day somewhere on the islands. The islands also are similar in their natural beauty. They all have volcanic moun¬tains and waterfalls, rain forests and beautiful beaches. The warm, clear water around the islands is filled with many kinds of sea creatures. There are giant sea turtles, whales, and dolphins as well as lots of tropical fish. The forests are full of beautiful birds and flowers. Many of them cannot be found anywhere else in the world. The Hawaiian Islands, in fact, have an interesting natural history. Until modern times, birds and insects were the only kinds of animals living on the islands, with just a few exceptions. The exceptions were the monk seal (a sea mammal) and a kind of bat (a flying mammal). There were no other mammals until people arrived in about 500 a.d. They brought some animals, such as pigs, for food. Other animals, such as mice, probably traveled to the islands hidden in their boats. Each of the islands also has features that are special. For example, the Big Island, Hawaii, is the only island with active volcanoes. Both Manna Loa and Kilauea on Hawaii occasionally erupt, pouring out hot lava and smoke. The island of Oahu is the site of the modern capital of Hawaii, Honolulu. This island also has one of the world's most famous beaches, Waikiki Beach, especially popular with surfers. And finally, the island of Maui is important to HawaUans for its role in the history of the islands. In 1800, Kamehameha the Great became the king of the islands. He established his capital on Maui, where it remained until early in the 20th century. Today, with its tropical climate and natural beauty, Hawaii is a major tourist attraction. People come from all over the world to view the volcanoes, the seacoast and the rain forests. They come to sunbathe or surf at the beaches, or they come just to relax in the warm, sweet air. This passage is about _______. The Hawaiian Islands are called remote because they are ______________ The Hawaiian Islands are closest to The temperature in the islands is The features that you can find on all of the Hawaiian Islands are Many kinds of birds and flowers on the islands You can infer from this passage that, apart from Hawaii, the other islands The island of Maui is especially known for its
