【答案】

(1)西高东低,呈三级阶梯状分布

(2)青藏高原

(3)塔里木盆地, 云贵高原

(4)喜马拉雅山脉

(5)秦岭 0

【解析】

试题分析:

(1)我国地势的总体特征是西高东低、呈三级阶梯状分布这种地势特征有利于海洋上的湿润气流深入内陆形成降水;许多大河滚滚东流沟通了东西交通,方便了沿海和内陆的联系;阶梯交界处水能资源丰富。

(2)我国地势各级阶梯上分布着不同的地形区。第一级阶梯包括青藏高原和柴达木盆地,地形以高原为主;第二级阶梯包括塔里木盆地、准噶尔盆地、四川盆地、内蒙古高原、黄土高原、云贵高原,地形以高原、盆地为主;第三阶梯主要包括东北平原、华北平原、长江中下游平原,以及辽东丘陵、山东丘陵和江南丘陵,地形以平原和丘陵为主。据图可知:C是位于我国地势第一阶梯的青藏高原。

(3)我国面积辽阔,地形复杂多样,山脉构成了我国地形的基本骨架,平原、山地、高原、丘陵镶嵌其中。据图可知:A为塔里木盆地;H为云贵高原。

(4)据图可知:G是巨大的弧形山脉喜马拉雅山脉,位于西藏自治区与巴基斯坦、印度、尼泊尔、不丹等国边境上,东西绵延3400多公里,南北宽约200~300公里,由几列大致平行的山脉组成,呈向南凸出的弧形

(5)据图可知:E是秦岭,它和淮河一线是我国东部地区重要的地理界线,在它的南北两侧,自然环境、地理景观和居民的生产生活习惯有明显的差异。是我国南方与北方地区的分界线;一月份0等温线通过的地方;800mm等降水线通过的地方;暖温带与亚热带分界线;湿润区与半湿润区分界线;温带季风气候与亚热带季风气候分界线;旱地与水田的分界线;亚热带常绿阔叶林与温带落叶阔叶林的分界线、河流有无冰期的分界线等。

【题目】【2016山东济宁】阅读下面短文,从每小题 A、B、C、D 四个选项中,选出能回答所提问题或完成所给句子的最佳答案。

Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.

The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, The Cathedrals and Red Canyon, the sandy ro cks have different colors. Sometimes the rocks are so brown that

they turn the sea brown, like coffee.

Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests—eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

About 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking(徒步)there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream(防晒霜)makes the water dirty. So it is necessary to manage the visitors. For example, people maynot use motor boats or go fishing in the lakes, and they need official papers to drive there.
