Humpback whales
| Humpback whales are sometimes called performers of the ocean. This is because they can make impressive movements when they dive. The name "humpback", which is the common name for this whale, refers to the typical curve shape the whale's back forms as it dives. Sometimes the humpback will dive with a fantastic movement, known as a breach. During breaching the whale uses its powerful tail flukes to lift nearly two-thirds of its body out of the water in a giant leap. A breach might also include a sideways twist with fins stretched out like wings, as the whale reaches the height of the breach. A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head. It blows a double stream of water that can rise up to 4 meters above the water. The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black, and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same. Humpback whales live in large groups. They communicate with each other through complex "songs". |

For generations here in the deepest South, there had been a great taboo（禁忌）: publicly crossing the color line for love. Less than 45 years ago, marriage between blacks and whites was illegal, and it has been forbidden for much of the time since.
So when a great job about an hour’s drive north of the Gulf Coast attracted him, Jeffrey Norwood, a black college basketball coach, had reservations. He was in a serious relationship with a woman who was white and Asian.
“You’re thinking about a life in South Mississippi?” his father said in a skeptical voice, recalling days when a black man could face mortal（致命的） danger just being seen with a woman of another race, regardless of intentions. "Are you sure?"
But on visits to Hattiesburg, the younger Mr. Norwood said he liked what he saw: growing diversity. So he moved, married, and, with his wife, had a baby girl, who was counted on the last census（人口普查） as black, white and Asian. Taylor Rae Norwood, three, is one of thousands of mixed-race children who have made this state home to one of the nation's most rapidly expanding multiracial populations, up 70 percent between 2000 and 2010, according to new data from the Census Bureau.
In the first comprehensive accounting of multiracial Americans since statistics were first collected about them in 2000, reporting from the 2010 census, made public in recent days, shows that the nation’s mixed-race population is growing far more quickly than many researchers had estimated, particularly in the South and parts of the Midwest. That conclusion is based on the bureau’s analysis of 42 states; the data from the remaining eight states will be released soon.
In North Carolina, the mixed-race population doubled. In Georgia, it grew by more than 80 percent, and by nearly as much in Kentucky and Tennessee. In Indiana, Iowa and South Dakota, the multiracial population increased by about 70percent.
Census officials estimated the national multiracial growth rate was about 35 percent since2000 according to the known result, when seven million people ----- 2.4 percent of the population chose more than one race.If a black man married a white woman 50years ago, the worst result was that _____.
| A．he was sentenced to death | B．he was considered to be immoral |
| C．he was criticized by the public | D．he was treated as a lawbreaker |
The underlined word “serious” in Paragraph 2 can be replaced by “____”.
| A．stable | B．bad | C．mixed | D．dangerous |
What can we infer from Paragraph 4?
| A．Jeffrey Norwood was born in Hattiesburg and grew up there. |
| B．Taylor Rae Norwood’s mother is a white-Asian. |
| C．70 percent of the people in Mississippi are multiracial. |
| D．Mississippi has the largest multiracial population in the US. |
Which of the following states had the fastest growth rate of mixed-race population?
| A．Georgia. | B．Tennessee. | C．North Carolina. | D．South Dakota. |
People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.What can we learn from Paragraph l?
A. Driverless vehicles are now legal in the whole USA.
B. Volvo will be the first to sell driverless cars.
C. Driverless cars are pointing us' a faraway future.
D. Google's self-driving cars have covered a long distance.We learn that Governor of California Jerry Brown_________.
| A． helped design self-driving cars. |
| B．supports self-driving cars on roads. |
| C．considers self-driving cars science fiction. |
| D．improved the self-driving car systems. |
What is the role of the systems mentioned in Paragraph 3?
| A．They can help people drive more safely. |
| B．They can take the place of drivers now. |
| C．They can make cars run without fuel. |
| D．They can help cars run much faster. |
According to Richard Mason, what is the biggest challenge for driverless cars?
| A．They are not allowed to run on the road. |
| B．Their technical problems remain to be solved. |
| C．They are now too expensive for consumers. |
| D．They are more dangerous for people on the street. |

Born in America in 1898, William was an extraordinary boy, gifted with an amazing IQ between 250 and 300. The genius went to a grammar school when he was only 6 years old and graduated just within 7 months. At the age of 11, he became the youngest student of the Harvard University. He graduated with high scores at the age of 16 and entered Harvard Law School at 18.
Gifted with an amazing IQ between 220 and 230, Terence Tao makes it to this list of the people with the highest IQ in the world. Born in Adelaide, Australia in 1975, this genius first displayed his incredible intelligence at a mere age of 2, when he managed to solve basic arithmetic questions on his own. At the age of 16, he graduated with both Master's and Bachelor's degrees at the Flinders University. He has been considered as ''Mr. Fix it " by Charles Fefferman, who is a professor of Mathematics at Princeton University, and many other mathematicians want to interest him in their problems.
This 31-year-old Japanese-American astrophysicist lands him third in this list. At the age of 12, Christopher Hirata already worked on college-level courses, around the time most of us were just in the 7th grade. At the age of 13, this gifted kid became the youngest American to have ever won the gold medal in the International physics Olympiad.
At the age of 16, he was already working with NASA on its project to conquer planet Mars. After he was awarded the Ph.D. at Princeton University, he went back to California Institute of Technology.
The next person with very high IQ is Albert Einstein. With an IQ between 160 and 190, Albert Einstein is the genius behind the theory of relativity, which has had great impact on the world of science.

Endless playing of songs like All I want for Christmas in shops during the festive season doesn’t just drive us mad —the songs also make us more careless with our money, research has warned.
While repeated performance of Jingle Bells may seem like an innocent attempt to raise customers’ spirits during the nightmare of Christmas shopping, the songs also have a more delicate impact.
“Background music, or “Muzak”, can be used by marketers to impose cultures ---such as the commercialization of Christmas--- onto consumers and influence their behaviour,” experts said.
Dr. Alan Bradshaw of Royal Holloway, University of London, said, “Festive jingles are force-fed to Christmas shoppers in a bid to change their mood, influence their sense of time and what sort of products they buy. In other words, this is an attempt to control your shopping habits in a way that you might hardly be aware of.”
“Often we are told that we have the freedom to choose where we want to shop, but during Christmas the use of music in this way is so common that our freedom to choose disappears.”
Dr. Bradshaw and Prof Morris Holbrook of Columbia University examined the phenomenon and found that retailers often “dumb down” the music played in shops to relax customers, meaning it is easier to control their behaviour.
It is thought that slowing down the rhythm of music in shops can trick customers into thinking less time has passed, and therefore spend more time examining the shelves, for example.
Some providers of background music have been known to promote their services by claiming they can boost profits by controlling the behaviour of customers.
“A common trick is to take a popular current song and record an instrumental version which can be slowed down or sped up at different time of the day to influence behaviour in different ways,” Dr. Bradshaw said.
Background music is often classed as “Muzak” in honor of the Seattle-based company which began producing its soft-sounding melodies in the 1930s.According to Dr. Bradshaw, in what ways does Christmas music influence customers?
①their mood ②their income ③their sense of time ④ the sort of products they buy
| A．①②③ | B．①③④ | C．②③④ | D．①②④ |
Shopkeepers slow down the rhythm of music in shops to ___________.
| A．let customers spend more time shopping |
| B．make customers and sales assistants relaxed |
| C．let customers enjoy the beautiful music |
| D．help customers find what they really want |
What kind of music is now often adapted to influence customers in shops?
| A．Classical music | B．Popular modern songs. | C．Folk songs. | D．Jazz music. |
What is the best title of the passage?
| A．Music makes happy Christmas |
| B．Christmas “Muzak” |
| C．How to make Christmas music? |
| D．Christmas music makes us spend more |
