教材试题 Unit 3 A New Dimension of Life

Unit 3 Under the seaUsing LanguageReading and discussingA NEW DIMENSION OF LIFE19th JanuaryIm sitting in the warm night air with a cold drink in my hand and reflecting on the day a day of pure magic! I went snorkelling on the reef this morning and it was the most fantastic thing I have ever done. Seeing such extraordinary beauty, I think every cell in my body woke up. It was like discovering a whole new dimension of life. The first thing I became aware of was all the vivid colours surrounding me purples, reds, oranges, yellows, blues and greens. The corals were fantastic they were shaped like fans, plates, brains, lace, mushrooms, lettuces, the branches of trees and the horns of deer. And all kinds of elegant fish were swimming in and around the corals.The fish didnt seem to mind me swimming among them. I especially loved the little orange and white anemonefish that hid in the poisonous tentacles of the sea anemones. And I also loved the small fish that clean the bodies of larger fish I even saw them get inside their mouths and clean their teeth! It seemed there was a surprise waiting for me around every corner as I explored small caves, shelves and narrow passages the yellow and green parrotfish hanging upside down, gathering tiny plants off the coral with its hard bird-like mouth；a yellow-spotted red sea-slug sliding by a blue sea-star；an orange and blue-striped angelfish looking straight at me；a large wise-looking turtle passing so close to me that I could have touched it.There were other creatures that I didnt want to get too close to an eel with its strong sharp teeth, with only its head showing from a hole, watching for a tasty fish (or my tasty toe!); and the giant clam half buried in some coral waiting for something to swim in between its thick green lips. Then there were two grey reef sharks, each about one and a half metres long, which suddenly appeared from behind same coral. I told myself. They werent dangerous but that didnt stop me from feeling scared to death for a moment!The water was quite shallow but where the reef ended, there was a sharp drop to the sandy ocean floor. I thought I was very brave when I swam over the edge of the reef and hung there looking down into depths of the ocean. My heart was beating wildly I felt very exposed in such deep clear water.What a wonderful, limitless world it was down there! And what a tiny spot I was in this enormous world!1 Glance quickly through the diary entry on the previous page and then number the paragraph topics in the correct order.
