Do you know that more than half of the people living in Copenhagen(哥本哈根), the Danish capital, ride a bike to school or work every day? The city has set a goal(目标)to become the world's first carbon neutral(碳中立) capital by2025.

Cycling(骑行)is actually a faster and more time-saving way to travel in Copenhagen.That's why you'll find more bikes than people and more than 5 times as many bikes than cars in this city!

Copenhagen is a cycling paradise(天堂). The city has done its best to encourage people to ride bikes-it has built more than 1,000 km of cycling roads. The city planners have made plans to help park bikes and repair bikes for free--wow!

Copenhagen's cyclists hardly break traffic rules. Several of the city's main streets are only used for bike lanes(车道). Bike lanes along major roads are wide. Copenhagen is building 38 highways along the main city roads. The city's subways also allow cyclists to bring their bikes in the train, free of cost

The city planners are working hard to make cyclists feel safe So when cyclists get closer to a main crossing, sensors(传感器)down the streets ‘tell’ the traffic lights to give them a ‘green’ light,which means cyclists don' t have to worry about the heavy traffic. Isn't that cool? One smooth journey from home to school! Even in the cold winters, the workers clean snow on the cycling lanes before car lanes.

Lately, however, the city is facing a new problem-there are not enough parking lots for cyclists. Some people now start leaving their bikes just about anywhere. Perhaps the best way is to make more space for bikes or build underground parking lots.

At the same time, other big cities are following Copenhagen's example, such as London, Paris,New York, Beijing and San Francisco They are all taking actions to encourage cyclists.

1.What goal does Copenhagen hope to reach by 2025?

A.To build more and wider roads for cyclists.

B.To set a good example for other cities to follow.

C.To encourage more people to go to work by bike..

D.To become the world’s first carbon neutral capital.

2.Much more people in Copenhagen ride bikes than driving because_______.

A.the traffic is too heavy B.it's faster and saves more time

C.there are more bike lanes D.the city doesn't allow driving

3.What problem is the city facing now?

A.Other cities are following its example. B.Some cyclists often break traffic rules.

C.There isn't enough space for bike parking. D.Car drivers are not pleased with cyclists.

Do you know what the hump(驼峰) of a camel is used for? If you answered to store water, guess again. In fact, a camel's hump is a place for storing fat.

Most animals, including humans, store fat throughout their bodies, under their skin. But camels store their fat in one place, their hump. A hump can weigh as much as 80 pounds. Why do camels keep their fat this way? The answer is most likely because of their environment. Camels can go up to two weeks without eating because they have this fat to live off.

Also camels are great at handling(处理，应付) changes in body temperature. Their humps can help the camels keep cooler. Their coats also help them adapt(适应) to the heat. While the coat is thick, it reflects(反射)the sunlight and protects the camel from the heat that rises off the desert sand.

There are two kinds of camels, those with one hump and those with two humps. Camels with one hump are called Dromedary or Arabian camels. They live in the dry deserts in West Asia. Camels with two humps are called Bactrian camels. They live in Central and East Asia.

Besides their humps, camels have a lot of interesting facts. They can live between 40~50 years. They can carry about 400 pounds and run up to 40 miles per hour. It's true that camels can go long time without drinking water, and they can drink about 26 gallons of water at a time. Camels can also close their nostrils(鼻孔). So whether a camel has one hump or two, it is one amazing animal that is very well adapted to its environment.

1.What is a camel's hump used for?

A. Storing water.　　 B. Storing fat.

C. Carrying food.　 D. Carrying riders.

2. From the passage we can learn that ________.

A. camels' humps are very interesting
