Unit 5 What an adventure! My parents and I had just driven down the narrow mountain road from Marrakesh, with all its sharp bends, and had finally arrived at Merzouga.Before us stretched the unending sand dunes that marked the beginning of the Sahara. A small boy walked past with a group of noisy goats as I took a long look at the yellow roadside sign that told us we were entering a “fragile natural environment”.I made a resolution to respect and protect this unique landscape while I was here.We set off, our vehicle quietly running over the sand and small stones.It wasn’t long before we were surrounded by enormous sand dunes towering above us on all sides. The wind was blowing grains of sand from the tops of the dunes, the sun was beating down hard and bright, and the sky was a deep shade of blue that I had never seen before. The wild beauty of the desert was about to reveal itself.There was not a plant to be seen.The desert appeared completely empty, which was calming and threatening at the same time.The colours of the dunes contrasted strikingly with the blue of the cloudless sky. 词汇 积累 1.stretch /stret /v.延伸；绵延；伸展；拉长 2.fragile /'fr d a l/adj.脆弱的；易碎的 3.resolution / rez 'lu n/n.解决→决心，决定(熟词生义) 4.tower /'ta (r)/n.塔→vi.高耸；超过 (词类活用) 5.reveal /r 'vi l/vt.显出；展示；揭示；透露 6.threatening /'θretn ?/adj.威胁的；恐吓的；阴沉沉的 7.beat down (阳光)强烈照射，曝晒 佳句 背诵 1.Before us stretched the unending sand dunes that marked the beginning of the Sahara.(倒装句) 在我们面前绵延不绝的沙丘标志着撒哈拉沙漠的开始。 2.It wasn’t long before we were surrounded by enormous sand dunes towering above us on all sides.(It wasn’t long before...) 很快我们就被四周高耸的巨大沙丘包围住。 3.The wind was blowing grains of sand from the tops of the dunes, the sun was beating down hard and bright, and the sky was a deep shade of blue that I had never seen before.(场景描写) 风吹动着沙丘顶上的沙粒，阳光猛烈而耀眼地照射着，天空是我以前从未见过的深蓝色。 Period Ⅰ Starting out & Understanding ideas———通文本 Step Ⅰ Read for the main idea (Ⅰ)Read the text quickly and match the main ideas with the paras.
