读图1,完成问题。

小题1:如果该图是从极地上空所视地球自转图,则甲点位于乙点的

A.东南方

B.西南方

C.东北方

D.西北小题2:条件同上,下列叙述正确的是

A.自转线速度甲地大于乙地

B.自转角速度甲地小于乙地

C.地方时相差11小时

D.12月22日白昼时间甲地大于乙地小题3:若该图是某地近地面反气旋示意图,则甲乙两地风向为:

A.东南风、东北风

B.东南风、西南风

C.西南风、西北风

D.东北风、西北风小题4:若该图为控制亚欧大陆的主要天气系统,则:

A.开普敦正值雨季

B.南极地区常见极光

C.华北平原水稻生长旺盛

D.伦敦的当月平均气温高于哈尔滨小题5:若该图为控制北太平洋西岸沿海地区的天气系统时,则:

A.此时江淮地区出现梅雨天气

B.长江下游流域出现伏旱天气

C.武汉、南京等地多为连续性暴雨

D.华北平原进入春旱季节

答案

小题1:B

小题2:D

小题3:C

小题4:D

小题5:B

本题考查地球运动、天气系统和读图分析能力。

小题1:根据图示的自转方向判断为南半球上空,故甲位于乙地的南方;从东西方向上看,从乙地看甲地与自转方向相反,故为向西。

小题2:地球自转角速度规律:除两极点外,处处相等;线速度规律:纬度越高,线速度越小,故甲乙两地的角速度相等,线速度乙大于甲。

小题3:若为近地面反气旋,则根据水平气流呈顺时针,故判断为北半球,则甲处的风向由中心指向四周,并向右偏,形成西南风;乙处水平气压梯度力由中心指向四周,风向向右偏,形成西北风。

小题4:结合上题分析,当高压中心为控制亚欧大陆的主要天气系统时,北半球为冬季,南半球为夏季,即可排除A、B、C三项。

小题5:结合第3题分析,当高压中心为控制北太平洋西岸沿海地区的天气系统时,即夏威夷高压势力强盛时,此时为7、8月份,长江下游流域可能出现伏旱天气。

"What does the middleman do but add to the price of goods in the shops " Such remarks are aimed at the intermediate operations between manufacturers and final customers. This practice usually attracts a lot of attention from the public and the press and the operation most talked about is what is often called wholesaling.The wholesaler buys goods in large quantities from the manufacturers and sells them in smaller parcels to retailers, and for this service his selling price to the retailer is raised several percent higher. But his job is made more difficult by retail demand not necessarily running level with manufacturers’’ production. Because he adjusts or regulates the flow of goods by holding stock until required, he frees the manufacturer, to some extent, from the effect on production of changing demand and having to bear the whole risk.The manufacturer can then keep up a steady production flow, and the retailer has no need to hold heavy stocks, who can call on the wholesaler for supplies any time. This wholesale function is like that of a valve in a water pipe. The middleman also bears part of the risk that would otherwise fall on the manufacturer and also the retailer.The wholesaler provides a purely commercial service, for which he is too well rewarded. But the point that is missed by many people is that the wholesaler is not just someone adding to the cost of goods. It is true one could eliminate the wholesaler but one would still be left with his function: that of making sure that goods find their way to the people who want them.

The wholesaler obtains higher selling prices for________.

A.small parcels he sells

B.goods he buys in bulk

C.the service he provides

D.the information he offers
