(1)比较甲、乙两地气候特征的差异并分析原因。(3分)
(2)甲地所在国家是世界上人口增长数量最多的国家，分析原因。(3分)
(3)分析甲地的气候特征对当地农业生产的影响。(3分)
(4)与乙地同纬度的大陆西岸地区气候干旱。分析该纬度大陆东西两岸气候差异的形成原因。(3分)
正确答案及解析
正确答案
解析
(1)乙地冬季气温较甲地低，雨季较甲地长，夏季降水较甲地少。原因：甲、乙均为热带季风气候，但乙地纬度较甲地高，且冬季受冬季风影响，所以冬季气温较甲地低。甲地受西南季风影响，夏季降水较多，但雨季较短．而夏秋季乙地受东南季风和台风影响降水丰富．雨季较长。 (2)甲地所在国家为印度，印度生育观念落后，早婚现象严重，且受宗教的影响，人口出生率较高。而且，目前的人口死亡率较低，加上印度人口众多，导致其成为世界上人口增长数量最多的国家。
(3)有利影响：全年高温，热量充足，作物生长期长；雨季降水多，有利于作物生长。不利影响：降水变率大，农业生产易受干旱和洪涝灾害的影响。
(4)在北回归线附近的大陆东岸由于受海陆热力性质差异影响形成了亚热带季风气候，冬季盛行西北季风，温和少雨，夏季盛行来自海洋的东南季风，高温多雨。大陆西岸地区受副高或东北信风的控制，形成的是热带沙漠气候，全年高温干旱。

The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
