Climate change will force exhausted birds migrating to Europe from Africa to travel further, with possibly disastrous consequences, according to a study.

The annual voyage of some species, which fly north in search of food and suitable habitats, could increase by as much as 400 kilometers (250 miles), the research found. “Marathon migrations for some birds are set to become even longer,” said Stephen Willis, a professor at Durham University in Britain and the main architect of the study. “This is bad news for birds like the White throat, a common farmland bird. The added distance is a considerable threat. As temperatures rise and habitats change, birds will face their biggest challenge since the Pleistocene era (更新世), which ended 11,000 years ago,” he said in a statement.

Some 500 million birds migrate each year from Africa, some weighing as little as nine grams (three-tenths of an ounce). To complete a voyage that can be thousands of kilometers long, birds have to fatten themselves up to twice their normal weight. Some even shrink their internal organs (收缩内脏) to become more fuel efficient, so any additional distance may be dangerous.

The study finds that from 2007 to 2010, nine out of 17 species examined are going to face longer migrations, particularly birds that cross the Sahara Desert. Some birds travel the Sahara and the Mediterranean Sea in a one go, while others have a break in northern Africa before crossing. Many fly at night, when temperatures are cooler.

A few — such as the Blackcap — have started to adapt by spending winters in Britain, but such behavior remains exceptional, the study said. The study forecasts that the migration distance of the Orphean Warbler will jump from 2,700 kilometers (1,700 miles) to between 3,050 and 3,350 kilometers (1,900 and 2,100 miles), with even longer increases for the Subalpine and Barred Warblers.

1.What does traveling extra distance mean for some migrating birds?

A. Better living conditions.　　 B. Better physical health.

C. Stronger ability to fly.　　 D. Bigger threat to life.

2.To complete the marathon migrations, some birds have to do the following except ______.

A. have a break in the Sahara　　 B. put on more weight

C. reduce the size of internal organs　　 D. fly at night to avoid the heat

3.What can we infer from the text?

A. Birds have to migrate from Africa to Europe in winter.

B. Global warming is bad for all birds worldwide.

C. Birds that are of small size don’t need to migrate.

D. Some birds have to migrate unless they adapt to climate change.

4.What’s the best title of the text?

A. Climate change leads to disastrous consequence

B. The annual voyage of some species

C. How birds migrate for longer distances

D. Climate change pushes birds to migrate farther

The UN Environment Programme says that rising temperatures could mean the end for some migrating animals.

Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the World to another, perhaps stopping at feeding grounds on the way. Whales and turtles(海龟) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough, "said the report author Dr. Robert Hepworth.

Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.

With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.

Other animals picked out as particularly in danger include:

the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows.

·the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.

The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international level. The clock is running," said Dr. Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.

1. What is the main topic of the text ?

A．The effect of climate change on migrating animals.

B．How animals are adapting to changes in temperature.

C．The actions required to save migrating animals.

D．The need for government policies to prevent global warming.

2.By saying "The clock is running" in the last paragraph, Dr. Hepworth means that" ______"

A．it may be too late to save some animals

B．it is time to start protecting the animals

C．there is not much time to solve the problem

D．it takes time to complete the actions

A．They will only produce female babies.

3.WhVich of the following is mentioned as a consequence of rising temperatures?

A．More storms will affect the ability of whales to find their feeding grounds.

B．20 percent of all birds are likely to die out because of land loss.

C．Migrating animals are likely to start adapting to the changes more quickly.

D．Warmer oceans will increase the competition between different kinds of dolphins.

4.What can be inferred about turtles from the text?

       A．They are the only animals besides humans that suffer from cancer.

B．They have traditionally lived longer than other ocean-based animals.

C．Those born nearer a hotter area are more likely to be female.

D．Most kinds of turtles are likely to die out within 50 years.

As they migrate (迁移), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

Fascinating as their skills of flight are, migrating behavior has been difficult to study in　　 insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect (测出) such little creatures at such great heights.

To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.

Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate (补偿). Many migrating birds do the same thing.

The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

Migration(迁徙), is a long journey carried out by some birds to other areas where they hope to find more food and a warmer place to spend winter. Hundreds or thousands of miles' journey is actually difficult and dangerous. So why do birds migrate?1.However, it all comes down to survival.

Migrating for a Meal

For all birds, one of the main driving forces behind migration is food shortage. If all birds were to stay in the same warm regions all the year round, food would become lacking and producing their young would be less successful. As food resources are rich in the north each spring, millions of birds migrate there for the food supplies.2.

Migrating for Family

Over thousands of years, birds have evolved different migration patterns, timing and destinations to fly around the world to produce their young. Birds take advantage of a wide variety of suitable conditions to raise their young.3.

Migrating for Climate

Birds have evolved different types of feathers to survive different climates.4.So many birds leave the Arctic producing grounds, for example, when temperatures begin to fall and they need warmer habitats. Similarly, the hottest regions can be a bad environment for raising little chicks, and they will choose cooler areas to lay eggs.

Migrating for Predators(掠食动物)

Habitats that have rich food resources all the year round also attract a greater number of predators that can threaten their nests.5.It gives their young a better chance of reaching maturity. Many birds even migrate to specialized habitats that are nearly inaccessible to predators.

A.Birds always tend to fly to warmer places.

B.And changes in those climates can affect migration.

C.This increases the surviving chances of little chicks.

D.Birds have adapted themselves to their own surroundings.

E.There is more than one reasons for different birds to migrate

F.As the food supplies decrease in fall, they return to warm regions.

G.So birds migrate to different habitats to avoid being eaten by predators.
