Natural wonders crying aloud for help
“大声呼救”的自然奇观
cry在这里意为“喊叫”，cry for help则意为“呼救”。标题中crying aloud for help采用了拟人的修辞手法，呼应了正文中自然奇观正在消失的情形，表达了强烈的情感，引发共鸣。cry for...还可以表示“需要……，亟需……”。例如：
The disaster-stricken area is crying for help.
灾区迫切需要援助。
本文大量使用了拟人的修辞手法，如：标题中自然奇观在“大声呼救”；文中的I’m not a sea but a lake，I’m the rainforest of Madagascar和I’m a glacier at the...。第一人称的使用使文章读起来像是这些自然奇观的自我介绍，有一种这些自然奇观和人类面对面谈话的感觉，这使文章更具生动性和感染力，也使读者更能身临其境地感受到环境问题的严重性。
I'm not a sea but a lake. And I'm not dead. In fact, there is some life within me, and many plants and animals live around me. I'm saltier than any sea, so people can lie on my surface. Rivers flow into me. But now people take too much water from them. My water level is going down. I am becoming smaller year by year. Take less water, or I'll dry up within the next 100 years. Then I really will be dead!
The Dead Sea could die!
adj.咸的，含盐的
v.躺，平卧
n.表面，面
n.水平高度；相对高度
det.不那么多，更（较）少
The Dead Sea could die! 死海可能会死亡！
死海湖面海拔约– 430米，是世界陆地表面的最低点。同时，死海无出海口，进水主要靠约旦河。
Take less water, or I’ll dry up within the next 100 years.
少抽些水吧，不然用不了一百年我就干涸了。
句中的or用作并列连词，意为“否则，要不然”，后面跟的句子往往表示一种不好的结果。例如：
Wear your jacket or you’ll catch a cold.
穿上夹克，要不你会感冒的。
Walk faster or we’ll be late.
走快一点，不然我们就迟到了。
dry up意为“干涸；（供应等）耗尽，枯竭”。例如：
As the climate changed, the lake began to dry up.
随着气候变化，这个湖开始干涸。
I’m the rainforest of Madagascar. As my name suggests, I make rain for my plants and animals, such as monkeys, snakes and many kinds of flowers. For 80% of them, I’m their only home in the world. However, people are cutting down my trees for wood and to make space for farming. Please stop it. I’m disappearing.
Rainforest - forest ≠ rain
v.暗示，暗指
像，诸如，例如
n.木头；木材，木料
v.消失，不见
I’m the rainforest of Madagascar.
我是马达加斯加的雨林。
马达加斯加共和国（简称“马达加斯加”），位于非洲大陆以东、印度洋西部，是非洲第一大、世界第四大岛。该国森林面积约占国土面积的21%，珍稀动植物种类繁多，一些动植物为马达加斯加独有。位于马达加斯加岛东部的阿钦安阿纳雨林被联合国教科文组织世界遗产委员会批准作为自然遗产列入《世界遗产名录》。
I’m a glacier at the Glacier National Park in America. It’s a land full of ice and snow. Do you want to explore the white world in the film Frozen Then my home is the best choice. Two hundred years ago, there were about 150 glaciers. But now, there are around 25. Please stop climate change. I’m turning into Waterworld!
If Frozen turns into Waterworld…
n.冰川
adj. 国家的，全国性的
