Music for Humans and Humpback Whales

As researchers conclude in Science, the love of music is not only a universal feature of the human species, but is also deeply fixed in complex structures of the human brain, and is far more ancient than previously suspected.

In the articles that discuss the field of bio-musicology, the study of the biological basis for the creation and appreciation of music, researchers present various evidence to, show that music-making is at once an original human "business", and an art form with skillful performers throughout the animal kingdom.

The new reports stress that humans hold no copyright on sound wisdom, and that a number of nonhuman animals produce what can rightly be called music, rather than random sound. Recent in-depth analyses of the songs sung by humpback whales show that, even when their organ would allow them to do otherwise, the animals converge on the same choices relating to sounds and beauty, and accept the same laws of song composition as those preferred by human musicians, and human ears, everywhere.

For example, male humpback whales, who spend six months of each year doing little else but singing, use rhythms (节奏) similar to those found in human music and musical phrases of similar length—a few seconds. Whales are able to make sounds over a range of at least seven octaves (八度音阶), yet they tend to move on through a song in beautiful musical intervals, rather than moving forwards madly. They mix the sounds like drums and pure tones in a ratio (比例) which agrees with that heard in much western music. They also use a favorite technique of human singers, the so-called A-B-A form, in which a theme is stated, then developed, and then returned to in slightly revised form.

Perhaps most impressive, humpback songs contain tunes that rhyme. "This suggests that whales use rhyme in the same way we do: as a technique in poem to help them remember complex material," the researchers write.

1.The underlined words "converge on" in Paragraph 3 probably　 means__________.

A. tend towards　 B. refer to

C. turn into 　　 D. put forward

2.Which of the following shows the advanced musical ability in humpback whales?

A. They can remember complex material.

B. They can create pleasing patterns of music.

C. They can make sounds like drums continuously.

D. They can sing along with rhythms of western music.

3.What is the main idea of the article?

A. Animals are able to compose and enjoy music like humans.

B. Human beings borrow ideas in music from humpback whales.

C. Humpback whales are skillful performers in the animal kingdom.

D. Music-making it an ancient activity of both humans and animals.

4.The main purpose of the passage is to __________.

A. argue and discuss　　　　　 B. inform and explain

C. compare and advertise　　 D. examine and assess

Flying out of an airport in the United States is not always easy. You will need to complete the ticketing process, baggage check, and security clearance procedures before boarding the plane.

If you are flying on an international flight, you'd better arrive two hours before your plane is scheduled to leave. You might need more time in a busy airport in a large city. If you are traveling on a domestic (国内的) flight, you may only need to arrive at the airport 90 minutes before your plane takes off.

Every airport in the States is now moving its ticketing procedure to electronic ticketing device. By using a ticketing machine, you have the chance to choose a seat you like on the plane. If you use it to check-in your bags, you will only have to talk to the ticketing agent when you turn in your luggage to be tagged (加标签). At the same time a real person will be nearby to help you if you need it.

After you have checked in, you will have to pass through airport security. Have your ID card or passport and boarding pass ready to show the security officer when entering the security checkpoint line. Airport security is getting tight in the States today. You're not allowed to travel with any prohibited things like knifes or fireworks.

After the security staff has checked your travel documents, you shall put all of your belongings through a scanning machine and then walk through a metal detector (探测器) or a full body scanner. You need to take off your coat, belt, and sometimes your shoes to go through one of these scanners. Be sure not to have any metal in your pockets. If you do not understand a question you are asked at a security checkpoint, ask the person to repeat their question until you are able to respond with an accurate answer.
