CAADB试题分析：这篇文章为旅游者们介绍了热带的气候状况

【题目】I live in north Celebes which is near Philippines. Since early December 2010 most tropical regions have been frequently hit by rain. Just like my hometown, tropical regions only have two seasons, including the dry season that usually starts from April to September and the wet or rainy season which usually happens from October to March. But, it could be indeterminate. Sometimes the rainy season can come a month earlier or later. It can be prolonged(延长) even more than 4 months and so can the dry season. Even during the dry season, rain can occur several times in certain areas.

The prolonged dry season in tropical areas usually causes a lot of losses. It will be very harmful to local farmers, because most of the tropical areas are regions of the developing countries. Sometimes agricultural and plantation crops will be damaged because of so much dry land and the fact that the river used to flow the water for rice fields are also dry. Rain is very important for plants because rain contains many nutrients that plants are in great need of.

What’s more, if the prolonged rainy season arrives and then floods usually occur in certain areas of low lands. Even for the capital city of Jakarta floods have struck several times during the prolonged rainy season. In addition to floods, the rainy season can cause many diseases. During the dry season, diseases are usually caused by mosquitoes such as dengue fever. While in the rainy season, people who have the weak immune will be more easily attacked by some diseases such as flu, fever, diarrhea, and much more.

If you live in the other places and want to travel to the tropical regions, make sure that you have known much about the season and the effect for these months in which you want to travel as tourists. Only in that way, can you at least prepare to deal with tropical weather.
