A ten year old girl saved about one hundred other tourists in 2004 by warning them that a tsunami, a huge ocean wave, was on its way across the sea. She knew what was happening because she learnt about underwater earthquakes at school only a few weeks earlier, a newspaper reported.
“I was on the beach and the water started to go funny, ” Tilly Smith told the reporter from the newspaper. “There were bubbles and the water went back suddenly. I knew there was going to be a tsunami. I told Mum, ” she said.

拓展延伸
Around the world
Special buildings in Japan
Earthquakes are very common in Japan.
Many can cause a lot of damage. But
now there are new ways of constructing
buildings to make them safer and stronger
during earthquakes. The Yokohama Landmark Tower is one of the tallest buildings in Japan.
It is heavy and strong. It sits on rollers. This means the earth can rise and fall beneath the building without shaking it.

成“Don’t＋动词原形＋其他成分”。

① 以let开头的祈使句，如果后面跟第一、
第三人称名词或代词的宾格，在let前加

（3）在公共场合的提示语中，否定祈使句常用
“No＋名词/动词的 ing形式”结构，表示
“禁止做某事”。
eg: NO PHOTOS! 禁止拍照！
本题考查祈使句的反意疑问句的用法，否定祈使句的反意疑问部分用will you，故选A。

语法要点
祈使句的反意疑问句，肯定祈使句的反意疑问部分will you/won’t you；否定祈使句的反意疑问部分用will you。但以let’s开头的反意疑问部分用shall we。

（二）情态动词表推测
推测的情态动词有must, can, could, may, might等。它们在表示推测的时候用来说明说话者的主观看法。
从句式上理解情态动词表推测的用法：表示推测时，肯定句中用must, can, could, may, might；否定句中用can’t或couldn’t, may not或might not；疑问句中用can或could。
语法要点
从可能性上理解推测情态动词的用法：情态动词must, can, could, may, might表示推测时，其中must表示的可能性程度最大，表示“必然”。can，could, may, might都表示“可能”，其中might表示的可能性程度最小。可能性由大到小排列为：must→can→could→may→might。
