下图为1961—2008年四川省年平均暴雨日数分布图(单位:天)。读图回答问题。

小题1:由图中所示信息能得出的正确结论是

A.图中28度纬线与l06度经线交点处年平均暴雨日数小于3天

B.不同地形区的过渡地带年平均暴雨日数往往差别明显

C.从32度纬线与106度经线交点处沿32度纬线往西,年平均暴雨日数持续增大

D.总体而言,盆地内部年平均暴雨日数相对较少小题2:下列关于四川地区暴雨形成及其影响的说法正确的是

A.年均暴雨日数少的地区,各种地质灾害发生的可能性均更小

B.暴雨给四川地区农业生产带来的影响是消极的

C.山前地带往往更容易形成暴雨

D.川西南山地和盆地西部边缘形成暴雨的水汽来自于同一个大洋

答案

小题1:B

小题2:C

题目分析:

小题1:28度纬线与106度经线交点处附近的等值线为3,其周围的数据小于3,按照“大于大的,小于小的”的规律,该处的平均暴雨日数应大于3天,排除A选项;选项C可据图直接排除;从图中的暴雨分布来看,暴雨日数较多的地区主要在盆地内部(如成都平原及以西地区),排除D选项;四川盆地和横断山区的过渡地带等暴雨日数线分布比较密集,说明地形过渡地带平均暴雨日数差别明显,故选B

小题2:地质灾害的种类有很多,如地震、火山、滑坡、泥石流等,地震、火山的发生则与暴雨关系不大,排除A选项;川西南山地形成暴雨的水汽来自印度洋,盆地西部边缘形成暴雨的水汽来自太平洋。

      "Teenager" means people from 13 to 19 years old. Although they're young, they have to make many

important choices by themselves. They need to think about questions like these: Should we go to college?

What kind of jobs do I want? However, other people also influence their choices. Who influences teenagers?

      It depends on the kind of choice. When teenagers buy things,friends are the most important influence.

This is especially true for clothes and music. TV shows, advertisements and parents also influence teenagers.

In more serious things, parents are probably the most important influence. Some teenagers say it's best to

regard both parents and friends as influences. James, a seventeen-year-old boy says he's "just a crazy man",

he also says, "Parents are really important because they can tell you what's right and wrong. " But teenagers

also feel they need to make choices-to make their own mistakes. As one teenager girl said, "If our parents

don't let us make our own choices, maybe in the future we don't know how to do it. " And they feel friends

can often be a big help, especially because friends sometimes know more about their situation than their  

parents do.

      Do you depend on parents or others when you decide what to do and how to do it? Whoever you depend

on, the correct choice is the most important. Your future is in your hand.
