下图为某河流的年径流量变化曲线示意图。读图，完成下面问题。
(1)结合图就“河流的位置”和“河流的水文特征”两个教学内容分别设计一道单项选择题，并附答案。
(2)简要说明试题设计意图。
(1)①该河流位于()。 A．亚热带季风区
B．亚热带大陆西岸
C．温带季风区
D．高寒地带
【答案】C。
②能正确反映该河流水文特征的是()。
A．由雨水和地下水补给
B．冬季断流
C．有一个汛期
D．年径流总量大
【答案】B。
(2)第一题的设计意图是考查河流的水文特征和气候之间的关系．不同气候区河流的补给方式不同，由图中河流的年径流量变化可判断出河流的补给特征，进而判断出河流所处地区的气候。由图可知．河流有春汛和夏汛两个汛期，所以有季节性冰雪融水和夏季降水补给两种补给形式，因此可判断出河流位于温带季风区，既有冰雪又有夏季降水。
第二题的设计意图是考查河流年径流量变化曲线的判读，通过读图可判断出河流的年径流总量、流量季节变化、汛期和补给等方面的特征。图中明显有春汛和夏汛两个汛期，河流由季节性冰雪融水和夏季降水补给，且年径流总量小，冬季流量几乎为零有断流现象。

If you don′t think a phone is the rightgift for a lover, the smart choice this year is a smart phone.

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.
