根据下文回答问题：

在我国960万平方公里土地上，山地占2/3，大致可分为三级台阶。第一级台阶是世界第一大高原——青藏高原。第二级台阶从黑龙江最北端开 始，一直到云贵高原南部，平均海拔近2000米，包括内蒙古高原、黄土高原、秦岭、大巴山和云贵高原。自第二级台阶以东至东南沿海为华东平原，即第三级台 阶。上一级台阶都是下一级台阶的支撑或庇护伞。青藏高原是我国整个生态的屏障，它把寒冷空气挡在这座大墙之外，使它的东面和南面即第二级台阶形成了优良的 生态条件，温暖湿润，物种丰富。而第三级台阶属平原生态系统，现代城市生活基本上都集中在这里，第二级台阶丰富的物种资源为下一级台阶的平原生态系统提供 了生存的物资。三级台阶囊括了地球大多数生态类型，将地球自赤道至极地之间的多数陆地动植物承载其中，为人类的生存繁衍提供了物种资源。 三级台阶中最关键的是青藏高原， ★ 但目前的情况却不容乐观，由于全球气候变暖，连年干旱，青藏高原上的许多湖泊湿地渐渐干涸。青海湖是中国第一大咸水湖，现在每年退水13厘米，干涸的过程 中，矿物质析出，若干年之后，过高的矿化度会杀死湖内所有生物。近些年来过度放牧也导致了草场退化，进一步破坏了涵养水源的生态条件。一旦青藏高原上的高 寒草甸消失殆尽，整个高寒草甸将会被荒漠和沙漠所取代。青藏高原是地质灾害多发地，它就像一堆5-8公里厚的碎石镶在旋转的地球表面，顶端的线速度比平地 快很多，所以它的板块碰撞和地质灾害表现得更加突出。地震、塌方、雪崩、泥石流等比平原剧烈得多，常有半面山坡倾倒而下，山坡上的树木成片成片地随之被连 根拔起。由于气候变迁和人类无序开发，青藏高原植被覆盖率大大降低，风沙危害逐年增大。全球变暖，雪线退缩，使许多5000多米的雪山岩石裸露。冰融水量 减少，许多湿地与河流干涸，缺水的居民只能搬家。 云南省号称“植物王国”，但看到的绿色与之并不相符。云南省只有西南部的森林长势良好，而中东部大部分植被很稀疏，干热河谷和干荒地区生态 更加脆弱，水土流失相当严重，在喀斯特地形区的土层很薄，很容易被侵蚀。著名的云南石林，看上去虽然壮观，但从生态的角度去看，不过是一片石漠，在云贵许 多地点，正在形成大量新石漠区。红色土壤流失后，裸露出灰色的石灰岩，就像动物被剔去了皮肉，剩下肉架一样，比沙漠更难治理。在云南德宏地区的热带雨林， 人们砍掉它改种农作物，这样做是捡了芝麻，丢了西瓜。热带雨林是地球最重要而且无法替代的生态系统，农作物能够带来的经济效益与之相比不可同日而语。这里 的湿地、湖泊也在退缩或消失，以前碧波荡漾的纳帕海现在已消失不见。经询问才知道，是无序开发把地下水系破坏了，就像在我们的盆底钻一个孔，高原湖盆的水 全部漏掉了。

将以下6句话（注：省略了标点符号）还原到文中横线处__★____，排列正确的一项是（） ①正是这个“大水塔”维持了中国乃至东南亚的整个生物世界的新陈代谢 ②高原上的山脉就像一条条水坝，坝顶部几乎都是冰川 ③形成一个涵养水源的生态系统 ④它是亚洲生态系统的支柱 ⑤水是生命之源 ⑥既围出大面积湿地、河流与湖泊，又有冰雪融水源源不断地补给湿地

A．⑤①④③⑥②

B．④①②⑥③⑤

C．①②③⑥⑤④

D．④②⑥③⑤①

The desire for a better life is sometimes so big that it makes people leave their countries and their families and work in other countries. They know that they will have to face difficult moments，that they won’t be able to communicate with the persons around them，and that maybe they will have to work in illegal conditions to get the money they need for their families，but they all take these chances and they hope they will succeed.

On the other hand，there are people who immigrate(移民)just for the sake of the people they love. They leave their families to make other families with the people they love. Women go to meet their men who have chosen other countries to start a new life，even if they miss their families and friends. Maybe they don’t have a place to work but they are able to wait to see what destiny(命运) has for them.

There are also the cases of the people who are forced to leave their countries because of a war which threatens their lives. They’d rather start from the very beginning again than risk putting their lives in danger.

When well­developed countries see that their homeland is being “invaded” by lots of immigrants，they set new laws that make immigration harder. As a result of this，many illegal immigrants cross the borders and are eager to work，although they are paid only half the amount of money native workers receive for the same kind of job.

The opinions of the local people are varied and they range from total refusal to complete acceptance. Immigrants in countries which have large communities of them are fighting for the recognition of their social rights and for equal treatment.

Many immigrants have managed to be fully accepted by the communities where they live and have managed to change the opinions of the local people about them.

A．culture shock causes great anxiety in some immigrants

B．illegal immigrants cause great damage to developed countries

C．stricter laws should be set to prevent immigration
