问题 综合

阅读材料,完成下列各题:

       材料一:温室效应是指由于全球二氧化碳等气体排放量不断增加,导致地球平均气温不断上升的现象。原来二氧化碳等气体就像温室中的玻璃顶棚一样既能使太阳光顺畅地透射到大地,又能截留和吸收地表放散出的热量,这就势必导致大气温度升高,全球气候变暖。温室效应使冰川加速融化,海平面逐渐上升,沿海低地被淹,旱涝灾害更加频繁,最终造成世界各地农作物的减产。目前,世界各国正在积极研究控制和减少温室气体排放量的措施。

       材料二、据科学家公布的数据,全球陆地生态系统储存的碳总量是2.48万亿吨,其中有1.15万亿吨是储存在森林中的,所以把森林叫储碳库。我们国家去年发布的应对气候国家方案,公布的数据足以说明它的作用。就是1980年到2005年,这25年间,我们的森林吸收和固定的二氧化碳就达到51.1亿吨。

       材料三、装机容量100万千瓦燃煤电站与核电站消耗燃料及排放二氧化碳比较

燃煤电站核电站
消耗燃料约300万吨煤约30吨核燃料
排放二氧化碳约675万吨煤发电阶段不排放二氧化碳

(1)由材料中可以看出,全球气候有                  的趋势,这是由于人类大量排放二氧化碳等气体,产生    “                          ”造成的。

(2)将下列地理知识重新排序,组成地理联系,并将序号填入对应空格内:     A、全球气温升高 B、海平面上升 C、二氧化碳增加     D、燃烧煤、石油 E、沿海低地被淹 F、两极冰川融化
(3)你认为人类可以采取哪些措施来减少大气中的二氧化碳?                                                                                                                                                         
答案

(1)变暖     温室效应

(2)

(3)植树造林,增加森林面积;减少对煤炭、石油的使用量,寻找新能源。(合理即可)

     Traveling without a map in different countries, I find out about different "styles"(方式) of directions

(方向)every time I ask "How can I get to the post office?"

     Foreign tourists are often confused (迷惑的) in Japan because most streets there don't have name

signs; in Japan, people use landmarks(地标) in their directions instead of street names. For example,

the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past

a fruit market. The post office is across from the bus stop."

     People in Los Angeles(洛杉矶), the US, have no idea of distance on the map: they measure (衡量)

distance (距离)by time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's

about five minutes from here." You don't understand completely, "Yes, but how many miles away is it,

please?" To this question you won't get an answer, because most probably they don't know it themselves.

     People in Greece(希腊) sometimes do not even try to give directions because tourists seldom

understand the Greek language. Instead, a Greek will often say, "Follow me." Then he'll lead you through

the streets of the city to the post office.

     Sometimes a person doesn't know the answer to your question. What happens in the situation? A

New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't

know." People there believe that "I don't" is impolite. They usually give an answer, but often a wrong

one. So a tourist can get lost very easily in Yucatan!

     However, one thing will help you everywhere in the world. It's body language.

1. Which one of the following is probably an example of Japanese directions?

A. "Go south two miles. Turn west and then go another mile."

B. "Turn right at the hospital and go past a school. The library is right in front of you."

C. "The post office is about five minutes from here."

D. "The post office is at Street Kamira."

2. People in Los Angeles don't give directions in miles because ______.

A. they use landmarks in their directions instead of distance

B. they prefer to lead you the way

C. they often have no idea of distance measured by miles

D. they prefer to use body language

3. Greeks give directions by ______.

A. using street names

B. using landmarks

C. leading people the way

D. giving people a wrong direction

4. Where is Yucatan?

A. In the USA.

B. In Japan.

C. In Greece.  

D. In Mexico.

5. Which of the following is NOT true?

A. People in Yucatan always give right directions.

B. There are different ways to give directions in different parts of the world.

C. People in some places give directions in miles, but people in other places give directions in time.

D. A person's body language can help you understand directions.
