Penguins are flightless birds that spend half their time on land and half in the water.
1. They have dark and white feathers, and their wings have evolved into flippers (脚蹼). Most penguins feed on fish, squid and other forms of sea life caught while swimming.
2. They are mostly found in groups that include thousands of penguins. Penguins each have their own unique mating call, and they use that to locate their mate and chicks in such a large group.
Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold Antarctica.3. Several species are even found in the temperate zone, and one species, the Galátpagos penguin, lives near the equator (赤道).
Unfortunately, many penguin species worldwide are facing threats. The biggest is climate change and global warming. As the earth warms up, the sheets of ice have melted, and the algae (藻类)that grow under the ice decrease. The algae are eaten by tiny creatures called zooplankton. When there is a drop in zooplankton, it affects the fish that depend on it.4.
Another major threat is from oil spills. If coated with oil, penguins cannot float or swim in water. Also, if oil is swallowed, penguins will die from poison.5.
A.These birds are very social.
B.In fact, only a few of them live so far south.
C.Penguins are highly adapted for life in the water.
D.The biggest threat for penguins comes from humans.
E.They have a tendency to live in a community together.
F.As a result, penguins have less fish to eat and thus starve.
G.Others include overfishing, illegal egg harvesting, and natural enemies.

高一英语单项填空中等难度题查看答案及解析
Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.
In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point—Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise for different kinds of groups of birds and have been called“Bird Islands”．
Each March and April, when ice and snow covering the QinghaiTibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.
To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997.Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.
Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' nestbuilding, egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.
1.Why are more and more birds coming to the biggest saltwater lake in the Great Northwest?
A. Because it is getting warmer and warmer. B. Because it is being reformed
C. Because environments there are getting more and more agreeable for them to live in. D. Because the people there are becoming richer and richer
2.The birds feed on_______according to the passage.
A. floating fish and various grass
B. grass moving on the water surface and different kinds of fish
C. salt water and plenty of grains
D. corn from the local farmers
3.Which of the following statements is TRUE according to the passage?
A. The ice and snow covering the QinghaiTibet Plateau doesn't change into water, unless more than 20 kinds of birds come to the Bird Islands.
B. Flocks of birds fly up to the whole sky over islands to lay eggs.
C. Visitors can listen to the singing of birds from miles away, but they couldn't see any bird
D. “The ice on the Plateau begins to change into water” means spring is coming.
4.The officials go around the lake mainly to________.
A. let the farmers there know the animal protection law
B. tell the farmers there some knowledge about animal protection
C. call on people to love and protect the birds
D. all of the above
