In the past hundred years, the world’s attitude toward whales has changed a lot. The animals are no longer seen as frightening creatures and worldwide protection efforts have reduced whale hunting. Through careful observation, scientists have shown that whales are generally peaceful, playful creatures, and that they have a high level of intelligence.
But even now, some behaviour of whales is still a mystery. A lot of information gathered by whale researchers has raised new puzzles about the animals. Whales’ communication is particularly difficult to understand. Male humpbacks (also known as bulls) give off a sequence (一连串) of low moans（呻吟）, high screams and clicking noises. These noises are sometimes combined in songs that last as long as 30 minutes. And in a particular region, every male will sing the same song, making small changes every once in a while so that it evolves (逐渐形成) into a completely different song over time.
This behavior seems to be related to reproduction. During the mating (交配) season, a male humpback starts the long song sequence, stopping only to join a passing female whale (also known as a cow). Eventually, the bull and the cow may dive deep into the ocean, probably to mate. Male humpbacks’ songs are similar to what birds display to attract mates (配偶), except that the sound carries over many miles, attracting some other male humpbacks in the area. It’s very odd that a male would call his own competition to him, unless he actually wanted to test his strength against others. Some whale researchers believe that the songs are actually acoustic (听觉的) contests of strength.What can we infer from the first paragraph?
| A．We used to have wrong ideas about whales. |
| B．Whales are in danger of dying out today. |
| C．Whales have always been considered as fierce creatures. |
| D．Whales are only protected in some parts of the world. |
We can learn from the second paragraph that .
| A．male whales and female whales both sing songs |
| B．people can’t fully understand whales’ communication |
| C．people only understand the songs of male whales |
| D．the songs of male whales never change |
The last paragraph suggests that male humpbacks sing songs most probably to .
| A．find their own family members |
| B．work together with others to hunt |
| C．compete against other male humpbacks |
| D．frighten away other male humpbacks |

There are no exact differences between physics and other natural sciences because all sciences overlap(重叠）.In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects.
One major branch of physics deals with the states of matter—solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane.
A branch of mechanics is statics(静力学）,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism（磁力）,heat,light,and sound.From these branches of physics scientists find clues(线索） which have revealed(揭示） the constructions of atoms and how the atoms react to various kinds of energy. This knowledge is often called the basis of modern physics.Among the many subdivisions（细的分支）of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the “natural laws” of electricity to help in designing and electric generator(电动机）.Physics is not exactly different from other natural sciences because_________.
| A．physics and other natural sciences have parts in common |
| B．it is the scientific study of forces and qualities such as heat,light and sound |
| C．it studies the ways in which forces and qualities affect other objects |
| D．it is a part of other natural sciences |
The following statements are included in the study of dynamics except_________.
| A．the design and construction of skyscrapers |
| B．the motions of heavenly bodies |
| C．the motions of water pumped by a fire engine |

Among many branches of modern physics is _________.
| A．states | B．electricity | C．electronics | D．mechanics |

| A．electricity and magnetism,light and sound |
| B．the construction of atoms and their reactions to various kinds of energy |

Ted Shreds doesn't like cars.He wants people to stop driving because cars make the air dirty.Ted had an idea.He said,“I'm going to cycle around North America.I want to show everyone that cycling is a fun way to get around.If more people ride bikes,the air will be cleaner.”
He left his hometown with $160 in his pocket.When he got to San Diego,he met another cyclist.The cyclist invited Ted to speak at a big meeting about the environment.He said,“We'll pay your airfare to Texas and we'll pay you to talk about your cycling trip.”Two hours late,Ted was on a plane to the environmental conference and to a big surprise!
While he was at the conference,he met Deanna,it was love at first sight!They talked for six hours straight.
The next day,Ted called Deanna and asked her to finish the trip with him.Deanna said yes,sold everything in her apartment,gave her notice at work,and was on the road with Ted 20 days later!
“It was difficult at first,”said Deanna.“Ted got up every morning at 6:00 a.m.,but I wanted to sleep until noon.”After a few days,they started having fun.As they cycled from Florida to Montreal and then back to Vancouver,every day was an adventure.People paid for their food in restaurants and gave them extra money.Some people gave them $50 or $100.They slept in people's backyards and drank beer with motorcycle gangs.
On their way back to Vancouver,they stopped in Edmonton to visit Ted's relatives.During the stopover,they got married.People tied a “Just Married” sign and tin cans to the backs of their bikes.They got married.They now want to write a book about their trip.“We want people to know that you can be an environmentalist and still have fun,”Shreds said.Ted Shreds went cycling because_________.
