Ⅰ　阅读理解
What do the following animals have in common? Pandas, rhinoceros, Mexican burrowing snakes, pink pigeons and small tooth sawfish.
They are all endangered animals! Animals become endangered for a variety of reasons. Sadly, humans are behind every one of them!

For centuries, humans have hunted elephants for their tusks, and killed tigers for their beautiful furs, caught fish for food. While we still have elephants, tigers, and fish in the wild, we cannot say the same about many others that have simply died out!
Year 1505 was a dreadful turning point in the natural history of the island of Mauritius—European sailors discovered this beautiful island in the Indian Ocean and brought dogs, pigs, monkeys with them. The arrival of humans and those introduced animal species were bad news for dodo birds (渡渡鸟). About 50 pounds and flightless, dodo birds did not have any natural enemies until then. They picked fruits fallen from trees and built their nests on the ground. Shortly after humans set foot on Mauritius, however, dodo birds realized that they were in big trouble—men killed them for their meat, and those introduced animal species destroyed their nests and ate their eggs. The effects of excessive hunting and foreign species drove dodo birds to first become much fewer and then die out. The last dodo bird was killed in 1681.
Humans and animals have always competed for land and other natural resources. We clear an area of a forest for farming. We cut down trees and use wood to build beautiful houses. We build reservoirs to make sure that we have enough water to use. At the same time that we are trying to make our life comfortable, we destroy the habitats of wild animals.
More than once we have seen on television that rescue workers are trying their best to save seabirds in spilled (泄漏的) oil. More than once we have heard about how emissions of carbon dioxide (二氧化碳的排放) and other gases have raised the Earth temperature and caused global warming. Pollution has a serious and long­lasting effect. If we choose to do nothing and continue to pollute our planet Earth, our next generations will have to face an Earth without birds singing and beasts roaring.

Ⅱ　七选五
(2019·大连市高一联考)Recently some American scientists have given a useful piece of advice to people in industrialized nations. They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.__1__
The scientists say that the human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses.__2__So they are called “diseases of civilization”. Many cancers and diseases of the blood system are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.__3__However, a change in food is one of the main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains.__4__We eat six times more salt than our ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C
__5__But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.
A．Stone Age people lived a simple life.
B．These new sicknesses were not known in ancient times.
C．In that case, they would live much healthier.
D．Ancient people also got lots of physical exercise.
E．But today, we enjoy eating a lot of these.
F．People today probably don't want to live like our ancestors.
G．Modern people used to suffer from “diseases of civilization”．

2．B　上文提到，我们的身体不能应对生活方式的改变因此带来了一些新的疾病，现在人们称之为“文明病”，而以前呢？在古代却没有听说过这些疾病。故选B。
3．D　此处关联语境为新时期和旧石器时代人们的生活方式，5个选项中只有D与之匹配。
4．E　前面为古人的饮食特点，下文为现代人的饮食结构，而此处承上启下，作为过渡。
5．F　所在部分为全文结论。But表转折，后面为科学家建议的饮食结构，故空格处应表达与此相反的内容。
Ⅲ　概要写作
阅读下面短文，根据其内容写一篇60词左右的内容概要。
Every time we breathe or burn something we turn oxygen in the air into carbon dioxide. The carbon dioxide in turn is used by plants to breathe and is changed back into oxygen creating a balanced cycle. The total amount of carbon dioxide in the atmosphere is quite small. If we increase our oxygen burning—for example, by burning a lot of coal or oil to generate electricity or run our cars—and cut down trees, we increase the amount of carbon dioxide in the air. This makes the air a little heavier and it starts acting like a thicker blanket around our earth, warming it up. The actual amount of warming is only a few degrees but it is enough to disrupt (使混乱) the delicate balance of nature—melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as the polar bears and some rare birds.
The polar bears are born in dens or caves on land while their mother sleeps through the winter. The mother and the babies emerge around March famished (挨饿) from a long seclusion and must immediately hunt to feed themselves to stay alive. Now, polar bears cannot hunt on land; the only hunting they know is to catch seals from floating ice in the open ocean.
The floating ice is located at the edge of the polar ice cap—a floating frozen mass that covers the North Polar arctic region, which is all ocean. So in March the polar bear mother and cubs swim from the land in Spitsbergen to the edge of the polar ice cap so that they can hunt.
Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, even babies, are good swimmers. However, last year we saw that the polar ice cap had really shrunk in size due to meltdown from global warming.
This meant that the polar bears had to swim many miles from the land in Spitsbergen—sometimes hundreds of miles—to find the floating ice where they could hunt.
Swimming hundreds of miles, especially when they are famished and have hungry babies in tow is really very hard and many bears are dying through drowning and starvation.
写前导读：本文是一篇说明文。讲述了因为人类使用了太多的煤和石油，造成了二氧化碳的急剧上升，北极熊因此而面临着生存威胁。　
[精彩范文]
Due to our burning a lot of coal or oil, the amount of carbon dioxide is increasing very rapidly. (要点1) So the ice in the North Pole is melting quickly. (要点2) This is a great threat to the polar bears. (要点3) After a long hunger, they are weak and can not swim a long distance, but they have to swim a few miles and even hundreds of miles. (要点4) Many starve or get drowned on the way. (要点5)
