14.Scientists have always been interested in the high level of organization in ant societies.American researchers have watched ants build life-saving rafts (筏子) to keep afloat during floods.They also have documented how ant colonies choose their next queen----the female whose job is to produce eggs.
New technology is helping to improve researchers'understanding of the insects.But there is still a lot to be learned.
Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common.To save themselves,the insects connect their legs together and create floating rafts.Some ant rafts can be up to 20centimeters wide.
David Hu who is a mechanical engineer with the Georgia Institute of Technology,also known as Georgia Tech,says,"If you have 100ants,which means 600legs,99percent of those legs will be connected to a neighbor.So they're very,very good at maintaining this network."
David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering.They froze ant rafts and then look at them with the help of computed technology,or CT,images.The pictures showed that larger ants serve in central positions to which smaller ants hold.The larger ants form pockets of air that keep the insects afloat.
Scientists say small robots or materials that can change shape could be programmed in a similar way,working towards a shared goal.
Researchers at North Carolina State University are also studying ants.They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.Researcher Clint Penick says all the worker ants in the colony are females.His team found that the worker ants start a series of competitions or battles and that some workers become physically larger.

32.The duty of the queen ants is toD.
A.build rafts       B.keep organized
C.keep guard        D.lay eggs
33.The author takes fire ants as an example to tell usD.
A.how ants seek food perfectly
B.how ants connect their legs together
C.how ants communicate with each other
D.how ants save themselves from floods

A.Ants know the way to form a harmonious society.
B.The Georgia Tech researchers first discovered Indian jumping ants.
C.Small and shape-changeable things might work just like ants do.
D.All the worker ants in the colony are physically larger.
35.What's the best title of the passage?A
A.Ants'Ability to Organize         
B.Ants'Living Environment
C.The Life-saving Rafts of ants
D.The Election of the Queen Ant.

5.On a recent trip to California,I stopped by Natural Bridges,where the monarch butterflies overwinter.Many years ago,I livedclose enough to it that I could walk there regularly and study their gatherings-the most memorable experiences when living in California,This visit,however,turned out to be disappointing.Though the way to the protected monarch garden looked just as I remembered it,I spotted only a few butterflies there.So I had to drive about a mile south to Lighthouse Field a more open area visited by large numbers of bikers,dog walkers and tourists.Many monarehs-at least several hundred-gathered in a small forest of pines there.Why had they moved to this less hospitable habitat-John Dayton,a biologist from San Jose provided an answer.During the 1990s,a deadly disease killed off most large pines sheltering the monarch habitats at Natural Bridges,forcing monarchs to seek shelter elsewhere.Still,since the mid-1990s,the number of overwintering monarchs in California has declined by nearly 90 percent.Butterfly populations at Santa Paula  alone,for example,have dropped from about 120,000 to less than 1,000-the lowest figure in two decades.
In California,coastal development has reduced the area suitable for overwintering monarchs. Illegal logging,poorly regulated tourism and water withdrawals near the butterfly habitais are also  endangering the butterflies.
Throughout the butterflies'North American range,declines in milkweed plants-which monarchs need to reproduce-are also knocking down the insect's numbers.Chemicals are widely applied,wiping out the milkweed once growing in the agricultural land.
Climate change may worsen the monarchs'situation.As atmospheric levels of CO2 continue to rise,milkweeds are likely to produce fewer toxic compounds(有毒化合物) that protect both butterflies and caterpillars (幼蟲) from their enemies.Milkweed leaves also may get tougher. Caterpillars will have a harder time chewing the leaves.
66.Why did the author feel disappointed during his revisit to Natural Bridges?C
A.Because it had been overpopulated with Monarchs.
B.Because the monarch's living habit was changed a lot.
C.Because fewer monarch butterflies overwintered there.
D.Because the people there were not so hospitable as before.
67.Where did the author find those monarchs moved?A
A.Natural Bridges                  B.Lighthouse Field                  
C.San Jose                         D.Santa Paula
68.What caused a sharp decline of overwintering monarchs according to Para 3?A
A.The loss of large pines.        B.A disease of monarchs.
C.Water pollution.                D.Too many caterpillars.
69.According to the passage,the decline of the milkweeds is connected withD.
A.coastal development              B.illegal logging
C.poorly regulated tourism        D.the abuse of chemicals

2.Whether or not to go university will probably be the biggest educational decision you ever make.After battling with student finance,deciding whether or not to take a year out can be as terrifying as deciding where to move to for the three years.
Some students will have planned their year out for months,but,for others,slipped grades may force a gap year (間隔年),either to retake exams or to apply to different universities.Others might just need time to think.Thankfully,for U.K.Students,taking a gap year remains a good option and it can be one of the most productive and fulfilling years of their life.
Whether you've planned and budgeted for a year abroad,or have made a last-minute decision to delay your first year,the options are endless.Traveling,volunteering and so on are all there for the talking,With so many things on offer,it's important to remember that 12months won't be enough time to do all of them,so decide early and work towards making whatever you want to do a reality.
Researching a gap year is exciting,and often the place to start is at home.Family and fiends can be a great source of inspiration.Your school or college might fully equipped to advise you on what to do when further education is on hold.Don't understimate(低估)the power of the Internet,either.Typing a"gap year"into a search engine might seem too obvious,but planning to travel around the world for months on your own is not appropriate.
To stay at home or go abroad is likely to be the first question you consider,but in this era of budget flights,doing both is practicable.A European inter-rail ticket(火車票)can be as little as£159.For those loving traveling,they must be on the special watchfulness for tricks in the process.Agencies can organize your year abroad for you,and often,it is more effective to make the bookings through the agencies.But flights and other forms of transport within Asia and America are much cheaper when bought in the countries rather than bought in advance.

32.According to Paragragh 2,why do other students have to take a gap year?C
A.Because they are faced with financial problems
B.Because they dislike what they are learning
C.Because they haven't got satisfying grades
D.Because they intend to hang out for a year
33.The underline words"on hold"in Paragragh 4mean"B"
A.taken in     B.Put off    C.Given up     D.Turned put
34.What can we learn from the last paragragh?D
A.Few students can afford to go abroad
B.Traveling around Europe costs nothing
C.It's better to go to Asia and south America
D.Travellers should make sure they aren't cheated
35.The auther's attitude towards a gap year may best described asA
A.Supportive     B.negative      C.Defensive     D.Sensitive.

9.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 (節(jié)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 (八度音階),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.

63.The underlined words"converge on"in Paragraph 3probably meansA.
A.tend towards  B.refer to  C.turn into  D.put forward
64.Which of the following shows the advanced musical ability in humpback whales?B
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.
65.What is the main idea of the article?D
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.
66.The main purpose of the passage is toB.
A.a(chǎn)rgue and discuss        B.inform and explain
C.compare and advertise    D.examine and assess.

“Folk singers are more like poets than singers,” Li Yahe, a music businessman, once told China Youth Daily.

That saying perfectly describes Zhang Lei, the 34-year-old champion of the fourth “Voice of China” singing competition, which ended on Oct 7.

Critics thought Zhang’s success as a victory for folk singers. The Voice of China used to attach great importance to singing skills and vocal techniques, which are not necessarily what folk singers are good at. “Folk songs are more about emotions and storytelling,” said Li.

Folk is one of the oldest musical styles. It dates back to ancient times, when people sang about their everyday lives and the society around them.

A powerful comeback

Folk music became popular again in the Western world in the 1960s. During social revolutions, many young Westerners turned to the simple rhythms of folk. Pioneers included US singer Bob Dylan, whose songs are reflections of some social issues like the Vietnam War. Singers at that time used traditional folk instruments like the banjo, the upright bass, the mandolin and the piano.

In the late 1970s, folk music was introduced to Taiwan. The rise of singers like Lo Tayu and Chyi Yu popularized folk music, particularly among young Chinese people.

At that time, folk tunes were based on simple song structures, with pleasant chord progression and pretty lyrics, just like during old times. But they focused more on the dreams and sorrow of youth than on politics.

This continued to be the case when the folk “wave” swept Chinese mainland in the 1990s.

Folk pioneers

Sadly, it didn’t last long in China. Folk gave way to pop in the late 1990s, when people started living more fast-paced lives. But that didn’t mean folk music had disappeared from the music world entirely.

“The drop in the popularity of folk songs is because the business mode of the music industry is outdated, not because of the music itself,” folk singer Song Ke once said.

He was right. Recent years have seen folk songs gaining popularity, with the appearance of singers like Li Jian and Song Dongye.

“The popularity of the Internet has shocked the traditional profit model in music industry,” Lu Zhongqiang, manager of 13-Month, a music recording and publishing company, told Tencent Entertainment.

“Not-so-well-known music starts showing its strength when the production of mainstream music is declining,” he added.

1.Which would be the best title of the passage?

A. The History of Folk Music. B. Folk Music Pioneers

C. The Folk Music Industry. D. The Voice of China

2.The underlined world “it” in the last but four paragraph means________.

A. the popularity of folk music.

B. the focus of folk music.

C. the tradition of folk pioneers.

D. the new model of pop music.

3.Which statement is true according to the passage?

A. The Voice of China is very popular among young Chinese people.

B. Folk music once was a way to voice opinions about social issues.

C. Folk songs are more about expressing emotions than storytelling.

D. Outdated music mode is what leads to the decline of folk songs.

4.Which word can best describe the attitude of Lu Zhongqiang towards folk music?

A. Objective B. Confident.

C. Critical. D. Worried

One afternoon I was driving along the narrow dirt road. Ahead of me was a small red car with two people in the front seats. You can’t go very fast on a dirt road so I was driving carefully after it.

As we did, I began to watch the car in front of me. The driver was a middle-aged man with thinning hair, and beside him sat a woman with long, wavy blond hair. I could see the man’s face because he kept turning and talking and talking to the woman, but I couldn’t see her face because she never turned to look at him and answer.

As we drove along, the man turned again and again, talking to the woman. He leaned(靠) toward her and he smiled. But she sat without movement or response, staring straight ahead. She never once looked in his direction, and I wondered why.

I supposed of course that they were fighting. The long blond hair suggested someone beautiful. I thought she might be too coldhearted, the way a beautiful woman can usually be. I thought that the man might be her husband, or her lover, and that he was pleading with her. I thought she was turning cold to him: perhaps she was ending things completely, and he was trying to win her back.

We both slowed down to cross a little stone bridge, and once past it, on the straight, he turned again to her. I wondered then if I’d gotten it wrong. The man was definitely middle-aged, and the woman’s long, thick blond hair suggested youth. Perhaps the man was not her husband but her father. Maybe she was sitting silently still, not heartlessly. Or maybe she was weeping and unable to look at her father.

I watched them closely, trying to be sure. The man turned to her, smiling. She still did not look at him. We reached the stop sign at the end of Mount Holly Road, and the man turned once more to the blond woman. This time, at last, she turned toward him. She leaned over and licked his nose with her tongue. She was a golden retriever, a large dog used in hunting.

1.The real relationship of the two sitting in the front seats of the small red car is _______.

A. a husband and an angry wife

B. a loving father and a weeping daughter

C. a master and a big dog

D. lovers in quarrel

2.We can infer from the text that______.

A. the author followed the man out of curiosity at the very beginning

B. the man couldn’t match the woman beside him

C. the man loved the one sitting beside him very much

D. the man was a good husband or a good father

3.The underlined sentence in the text means_____.

A. he was begging her

B. he was playing with her

C. he was quarrelling with her

D. he was joking with her

4.Which is the most suitable title for the text?

A. A Poor Middle-aged Man

B. An Unexpected Companion

C. A Beautiful Proud Woman

D. An Unforgettable Experience
