题目内容

【题目】我国南极地区第34次科学考察中,中国科考队在罗斯海区域的“难言岛”完成了我国第5个南极考察站的优化选址作业。阅读材料完成下列各题。

科考日记一 3月21日是南极冬天开始的日子……4月和5月上旬,南极虽然不完全黑暗,但几乎没有足够的光线看清附近的冰山,直到8月,光线再次蒙蒙出现。

(1)难言岛位于昆仑站的___________方向,濒临___________洋。材料说明南极地区此时出现了___________现象。

科考日记二 这里夏季平均气温只有-33℃,如果有一丝微风,你会听到自己呼吸飘走时被冻住的声音,就像爆竹的噼啪声;七级大风真是平平常常,早上施放的探空气球,还没灌满气,就被吹爆了;暴风雪里的雪根本不是天上来的,而是地上卷起来的,南极年平均降水量55毫米,南极点附近只有5毫米。

(2)根据日记,概括南极地区的气候特征。

科考日记三 南极地区真是个天然实验室!在地球这个大系统内的一切要素变化的迹象,如气候变化、火山喷发、人类活动甚至太阳活动等,都可以通过物理的或化学的变化“记录”在南极冰盖的积雪和冰川里。全球已有许多国家在此建立了一系列科学考察站。

(3)结合所学知识,说明南极地区被称为“天然实验室”的地理原因。

科考日记四 虽然气候条件恶劣,但南极风光美丽迷人。资料统计,中国游客登陆南极大陆的人数从2008年的不足100人次到2017年的超过5000人次,十年时间里增长了50倍。

(4)假如你去南极旅行,结合南极环境请说明应携带的物品及旅行中保护环境的做法。

【答案】(1)东北 太平 极夜

(2)酷寒(气温低、严寒、寒冷) 干燥(降水少) 烈风(风力强、风速大)

(3)丰富的自然资源;独特的地理位置;原始的自然环境

(4)准备羽绒服、太阳镜等防寒、防护物品(携带物品答出一种即可,但必须与南极的特殊环境密切相关);垃圾要回收处理;保护南极生物资源。(答出一点,合理即可)

【解析】本题考查南极地区地理概况。

(1)据图可知,难言岛位于昆仑站的东北方向,濒临太平洋,3月21日太阳直射赤道附近,结合日记内容分析,此时南极地区开始出现极夜现象。

(2)结合材料分析,夏季平均气温只有-33℃”,表明其气温低,具有酷寒的特点;“七级大风真是平平常常”表明南极地区的风级极大,具有烈风的特点;南极年平均降水量55毫米,南极点附近只有5毫米。表明其气候降水少,具有干燥的特点。

(3)南极地区有丰富的自然资源丰富的淡水资源,是世界上最大的淡水宝库;有丰富的煤铁资源;有大量的海洋生物和独特的极地生物;独特的地理位置世界上最南的地点,跨经度最广的大洲;原始的自然环境未经人类雕饰,保留有人类活动影响较小的冰川等等,故南极地区被称为“天然实验室”。

(4)南极旅游时要注意防寒保暖,准备羽绒服、太阳镜等防寒、防护物品;旅行中要保护环境垃圾要回收处理;保护南极生物资源。

【题目】

Next time if you're unhappy or complaining about your life, don't turn to a cheerful comedy. You might find a tragedy (悲剧) is just the thing you need to make your day bright.

A team of researchers at Ohio State University, US, has found sad movies can make people happier, Science Daily reported last month.

Many people find tragedies make them realize how good their own lives are, the research showed.

Silvia Knobloch Westerwick, leader of the study, told the reporter that tragic stories often focus on themes of love, and this leads viewers to think about their loved ones and count their good and helpful things.

361 college students took part in the study. They were shown a sad movie. The movie was about two lovers who couldn't be together and finally died during World War II. Before and after the movie, the students were asked questions measuring (衡量) how happy the), were with their lives. Researchers also asked them before, after and three more times during the movie to measure various moods, including sadness.

Researchers found that the sadder students felt while watching the movie, the more likely they were to think about real people they had close relationships with in life. This increased their happiness after watching the movie.

Knobloch Westerwick also explained that sad feelings make people more thoughtful.

"Happy feelings show that everything is fine. You don't have to worry. You don't have to think about problems in your life," she said. "But sadness makes you think more seriously about your situation.So seeing a tragic movie may make you sad, but that will make you think more about your own close relationships and be more grateful."
