     Typhoons usually come to Taiwan in summer. They bring lots of rain. It gives us water to

use. But typhoons also bring us floods if it rains too much. After the floods, there may be

diseases such as dysentery or dengue fever. Typhoons also come with a lot of wind. The

wind damages houses, trees, crops and hurts people. So staying at home, preparing food

and water, and watching the news on TV are the safest things to do.

     The confirmed death toll (伤亡人数) in Taiwan caused by Typhoon Morakot, which

first hit the island on August 6th, causing the worst floods since 1959, is bad enough. By the

middle of this week, over 100 people were reported dead and more than 60 were missing.

But there had been fears that 500 people had been buried alive in Hsiao Lin, a village in the

wooded mountains of Taiwan's south, and even more in remote neighboring villages. These

made people feel a little comforted on August 12th, when almost 1,600 people were found

alive by a 25-helicopter search mission(任务). Survivors had not eaten for days and helicopters

dropped foods and drinks and began a slow evacuation(撤离), blocked by heavy rain. The

army says it does not know how many people may have died there. The government faced

criticism for not having arranged an evacuation as soon as it heard the typhoon was coming.

"We should brace ourselves(振作起来) against typhoons as if they are an invading enemy,"

said Chu Wen-sen, one of Taiwan's leading water-management experts.
