材料一:我国局部地区秋季等压线分布图

(1)图中M为锋线,简述此时甲地的天气状况。(2分)

材料二:乙、丙是我国苹果的主产区,果农为减少冻害对苹果造成的损失,在气象预报将有霜冻出现的夜晚,点燃发烟物,提高果园气温。

(2)乙、丙两省发展苹果生产的有利自然条件有哪些?(3分)

(3)阐释果农采取防冻措施所依据的地理原理。(2分)

材料三:甲城工业结构及变化图

(4)简析该城市节能减排的压力。(3分)

答案

(10分)

(1)受冷气团控制,气温低,气压高,天气晴朗。(2分)

(2)暖温带地区夏季光热充足;大陆性强,气温日较差大;地处黄土高原,宜林宜果土地广。(3分)

(3)点燃发烟物所释放的烟雾,能增强大气逆辐射,减少近地面大气热量损失,提高大气的保温作用。(2分)

(4)工业结构中重工业比重大,且煤炭、油气等工业比重呈上升趋势;(2分)能源利用中煤炭占绝对地位;(1分)这种工业结构和能源结构能耗大、排污大,使节能减排压力大。

题目分析:

(1)本题考查锋面气旋系统对天气的影响。图中等压线越往中心气压越低,为低压系统,M处为锋面,甲处位置位于冷气团一侧所以甲地气温较低,气压较高,天气晴朗。

(2)乙位于陕西省,丙位于山西省。两地都位于黄土高原,苹果为暖温带水果,黄土高原位于秦岭以北,属于暖温带地区,夏季光照热量充足,气温日较差大,适合种植苹果的土地面积广阔。

(3)本题考查大气的保温作用。地面是低层大气主要的直接热源,大气在增温的同时,也向外放出红外辐射,也是长波辐射,其大部分辐射向地面,称大气逆辐射,补充地面热量的损失,对地面起到了保温作用。点燃发烟物所释放的烟雾,能增强大气逆辐射。

(4)本题考查区域可持续发展。分析表格数据,该区域煤炭、油气工业比重上升,能源利用中煤炭占绝对地位。重工业比重大,能源消费结构以煤炭为主,污染大,不利于节能减排。

概念冷气团主动向暖气团移动暖气团主动向冷气团移动准静止锋是指移动幅度很小的锋。
天气特征过境前单一气团控制,天气晴朗单一气团控制,低温晴朗冷、暖气团势均力敌,或遇地形阻挡,锋面移动缓慢,或较长时间在一个地区摆动,造成阴雨连绵的天气。
过境时阴天、雨雪、刮风、降温连续性降水
过境后气压升高,气温下降,天气晴朗气温上升,气压下降,天气转好
降水的分布降水一般出现在锋后降水一般出现在锋前 
大气举例北方夏季暴雨,冬春季大风,寒潮,沙尘暴春季,长江以南和东北地区,常有暖锋活动。夏初,我国长江中下游地区的梅雨就是准静止锋造成的;冬半年的昆明准静止锋使得昆明和贵阳天气有很大差异。

     A simple flower made headlines in the British press last week. How could that be?

     British Prime Minister David Cameron and his ministers were attending a reception hosted by Chinese

Premier Wen Jiabao in the Great Hall of the People in Beijing. They insisted on wearing poppies (罂粟花)

in their buttonholes.

     What's wrong with that?

     According to the Global Times, Chinese officials apparently had asked the UK delegation not to wear

poppies. The British said that their poppies meant a great deal to them and they would wear them all the

time.

     So what's the significance of the poppy? It's a flower which has different cultural and symbolic

meanings for British and Chinese people.

     From the Chinese point of view, the poppy is a symbol of China's humiliation (dishonor) at the hands

of European powers in the Opium Wars of the 19th century. Britain forced China to open its borders to

trade-including in the narcotic opium (a drug that affects your mind in a harmful way)-which was made

from poppies grown in India.

     Yet from the British viewpoint the poppy is a reminder of the killing during World War I. Blood-red

poppies grew on the battlefields of Flanders in Belgium where many thousands of British, Belgian and

French soldiers died or were buried.Since then, Poppy Day or Remembrance Day (November 11) has

become a time in the UK to remember the sacrifices of British soldiers and civilians in times of war.

     So you can see that the poppy set off strong feelings in the hearts of Chinese and British people for

different reasons. And it makes sense for us to try to understand each other's standpoint.

     Of course cultural differences can also be interesting and funny. And what one nation or nation's

leader thinks is an acceptable gift may be viewed very differently by their guest from overseas. US

President Barack Obama famously gave a gift of an iPod to Britain's queen-a dull person with no interest

in music. Obama also presented Gordon Brown(when Brown was British prime minister) with a fine

selection of American movies. But they were in US format and impossible to play on British DVD players.

     Many countries have diplomats stationed overseas. Diplomats provide information and advice to their

governments back home. However, sometimes it would seem that even diplomats can overlook the cultural

significance of a small flower.
