[EX Q]: Article: 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 _ Sometimes the rainy season can come a month earlier or later. It can be prolonged 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 sre 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.

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.

[EX Q]: Article: These days, if you still think the cellphone is just for talking, you will get laughed at. Yes, it's true, voice-only handsets have become out of date. Today's do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minutes to use them. Some of the things a cellphone can do for you will be available this year: Surf at speed Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150. Listen as you go The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens. Say cheese Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video. Portable TV You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee. The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator... So what is there that a cellphone can't do?

[EX Q]: Article: An ATM that spits out cupcakes instead of cash is now filling a popular demand in the American market:late-night desire for freshly baked sweets.

Charles said each ATM serves about l,000 cupcakes per day.The machine is so popular that when it appeared in Manhattan, customers were lined up around the block to use _ Yet,inventing the first cupcake ATM was not as easy as convincing customers to use it.When the Nelsons started defigning the machine,they quickly realized nothing existed that could give a fully unbroken cupcake to a customer.The company had to partner with a European firm to develop the technology that could deliver a cupcake without dropping it several feet like a typical machine.After going through a seeond development cycle with the product, the ATMs can now satisfy tlle demand of growing customers and even make as many as four cupcakes at a time. In terms of the company, the-machine allows Sprinkles to do the impossible:increase hours of operation without raising costs.Now the company can sell cupcakes around the clock through the ATM without paying employees.
