看问题确认答案：
1. The people of Kiribati worry that one day their country will be taken away by a sudden high tide.
A. Right B.Wrong C. Not mentioned
分析：题干中涉及2层信息：The people of Kiribati worry 和 their country will be taken away by a sudden high tide. 利用题干中的关键词在文章中查找答案相关句 --文章前两句（注意题干中在用词和时态上的细节）。
The people of Kiribati are afraid （与题干中的第1层信息呼应）that one day in the not-too-distant future, their country will disappear from the face of the earth----literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. （与题干中的第2层信息呼应）
考点：考察考生的总结归纳能力。
补充：
Literally：adv. 照字义, 逐字地， 真正, 完全
Synonyms: actually, exactly, really, word-for-word
e.g. The city was literally destroyed.城市差不多全毁了。
2.High tides （与上一题相关）used to attack Kiribati when there was strong wind or heavy rain.
A. Right B.Wrong C. Not mentioned
分析：题干中涉及信息有两层：High tides used to attack Kiribati 和when there was strong wind or heavy rain.当题干中有表示条件的结构，尤其要认真对比原文和题干中对“条件”的描述和题干中的其他细节。利用题干中的关键词在文章中查找答案相关句。该题可能会丢分：没有注意到画线句。提示：在确认答案直接相关句后还需要把前后句再“扫一眼”，以防陷阱。
These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. “This never happened before,” say the older citizens of Kiribati.
补充：
Sweep: vt, vi (swept,swept)（常与off, away连用）清除; 掠过；拂过
e.g. The waves swept the deck. 波浪扫过甲板。
Destroy vt摧毁；破坏；毁坏；消灭；杀害
The fire destroyed all my books. 这场大火毁了我的全部书籍。
比较：
kill vt, vi杀死, 摧毁；破坏；毁灭
e.g. Ten people were killed in the train crash. 在火车相撞事故中有10人死亡。
kill time 消磨时间 
4.Scientists are not sure how serious the effects of global warming（暗示该题的答案位置应该与前一题的答案位置接近） will be.
A. Right B.Wrong C. Not mentioned
分析：题干中出现两层信息：Scientists are not sure和how serious the effects of global warming。 利用题干中的关键词在文章中查找答案相关句。
（What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned , pollutants(污染物) are released; these pollutants trap heat in the earth’s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers(冰川) and polar (极地的) ice caps.）
If the trend continues, scientists say, many countries will suffer.
补充：
suffer: v. 受苦；受难; 遭受（磨难）
e.g. She was suffering from a headache. 她正经受头痛之苦。
e.g. suffer death 丧生
5. The coral island nations of the Pacific have a long history of civilization.
A. Right B.Wrong C. Not mentioned
分析：题干中出现1层信息, 利用题干中的关键词在文章中查找答案相关句，发现文章中根本没有涉及到这些关键词的句子，所以答案为“没提到”。
6. The people of the coral island nations are unable to do anything substantial about the problem of global warming.
A. Right B.Wrong C. Not mentioned
分析：题干中出现3层信息：The people of the coral island nations, unable to do anything substantial和 about the problem of global warming。利用题干中的关键词在文章中查找答案相关句（注意利用关键词跳读），
Bangladesh, for example, might lose one-fifth of its land. The coral(珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate----they would be swallowed by the sea. The loss of these coral islands would be everyone’s loss. Coral formations are home to more species than any other place on earth.（跳读）
The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don’t have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.
7. Some industrialized countries are unwilling to spend money in reducing pollution.
A. Right B.Wrong C. Not mentioned
分析：题干中出现2层信息：Some industrialized countries和unwilling to spending in reducing pollution.利用题干中的关键词在文章中查找答案相关句，发现包含答案线索词的句子中并没有提到题干的内容，因此判断问题句的说法为“没提到”。
And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.
