China’s Jade Rabbit moon rover (月球车）has “ woken up” since it entered the lunar night two weeks ago. The moon rover, known as Yutu in Mandarin Chinese, and the Chang’e-3 lander were restarted by the Beijing Aerospace Control Center (BACC), China’s Xinhua news agency said.
It had been set to sleep for two weeks to ride out extreme climatic conditions and will finally undertake its scientific mission. The Jade Rabbit was “ put to sleep” on 26 December at the onset of the first lunar night of the mission. One night on the moon lasts for around two weeks on Earth and during this time, temperatures fall to -180℃ ---conditions too cold for the equipment to function in. There is also no sunlight to power the Jade Rabbit’s solar panels.
Zhou Jianliang, chief engineer with the BACC, explained: “ During the lunar night, the lander and the rover were in a power-off condition and the communication with Earth was cut off.
“ When the night ends, they will be started up with the power provided by sunlight and resume operation and communication according to preset programmes. He added that the Jade Rabbit surviving the lunar night showed Chinese technology had proved successful.
The Jade Rabbit and the lander compose Chang’e-3 landed on the moon on 14 December. With the landing, China became one of only three nations to soft-land on the moon, and the first to do so in more than three decades.
Scientists said the mission was designed to test new technologies and build the country’s expertise of space exploration. The Jade Rabbit will gather scientific data and capture images from the Moon. China was planning further missions planned to collect lunar soil samples and it is thought officials are looking to conduct manned lunar landings if they prove successful.Jade Rabbit fell into sleep because ________.
| A．there was something wrong in the machine |
| B．the Chang’e-3 lander struck it by accident |
| C．it was designed to avoid the bad weather |
| D．it had completed the scientific mission |
According to Zhou Jianliang we can know that ________.
| A．on the moon the rover can’t communicate with the lander |
| B．sunlight is the necessary power for the rover and the lander |
| C．Chinese technology has been regarded the most successful |
| D．the lunar night can destroy the equipment on the moon |
It can inferred from the passage that ________.
| A．China had made great achievements in 10 years |
| B．no country can be equal to China in exploring space |
| C．scientists can get more proof to research the moon |
| D．the soil from the moon has been taken to China |
What does the author intend to tell in the passage?
| A．Jade Rabbit wakes up to begin moon mission. |
| B．Jade Rabbit was put to sleep on the moon. |

All of us, at some point, experience nights where we have difficulty falling asleep or staying asleep. The National Institute of Health estimates that one in three adults has bouts of infrequent sleeplessness or insomnia, while one in 10 sufferes from chronic insomnia. Being unable to get a good night's sleep can cause disruptions in our daytoday life. But persistent sleeplessness can lead to physical and emotional health problems.
The body needs sleep to rejuvenate itself and rebuild the cells necessary to keep the immune system strong and the brain functioning properly. Everyone's body requires a different amount of sleep to accomplish these goals. The average amount of sleep needed by an adult is around seven or eight hours a night. However, some people can function quite well with less than that, while others need more to be at peak performance.
Sleeplessness can be caused by many different things. Most people experience sleeplessness for a short period of time due to an outside stimulus such as stress, improper diet, a poor sleeping environment or an acute medical concern such as the flu. Once the stimulus passes, the ability to sleep will usually return. Chronic sleeplessness may be caused by ongoing health concerns such as the physical pain of arthritis or the emotional pain of anxiety and depression.
Prolonged sleeplessness can have a negative effect on the way the body performs daily tasks. Those that suffer from sleepless nights may find themselves feeling drowsy or fatigued during the day. The ability to concentrate or focus on a task diminishes and you are less mentally alert. Because the body needs sleep to support a healthy immune system, those that are sleepdeprived may be more susceptible to both acute and chronic illnesses such as high blood pressure and diabetes.
Sleeplessness not only takes a toll on your physical self but also your emotional wellbeing. Being unable to sleep well for a few nights may only produce minor irritability. However, if sleeplessness becomes chronic, the price could be much higher in the form of anxiety, depression and possibly substance abuse. Those with chronic sleeplessness may turn to controlled substances such as sleeping pills and alcohol to aid them in their quest for a good night's sleep.
There are numerous home remedies for mild sleeplessness. Prepare your body for sleep by avoiding caffeinated drinks such as tea or coffee before bed. Don't exercise strenuously before bedtime; instead do something relaxing such as meditate or take a warm bath. Go to bed only when you feel sleepy and not because of a selfappointed bedtime.Finally, create a favorable sleeping environment by removing stimulants from your bedroom such as extra lighting or a television. If you still cannot find relief, it may be time to visit your physician for help. A sleep study will be done that can help to determine the cause of the sleeplessness and possible solutions.
Mark Twain has been called the inventor of the American novel.And he surely deserves additional praise：the man who popularized the clever literary attack on racism.
I say clever because antislavery fiction had been the important part of the literature in the years before the Civil War.H.B.Stowe's Uncle Tom's Cabin is only the most famous example.These early stories dealt directly with slavery.With minor exceptions，Twain planted his attacks on slavery and prejudice into tales that were on the surface about something else entirely.He drew his readers into the argument by drawing them into the story.
Again and again，in the postwar years，Twain seemed forced to deal with the challenge of race.Consider the most controversial，at least today，of Twain's novels，Adventures of Huckleberry Finn.Only a few books have been kicked off the shelves as often as Huckleberry Finn，Twain's most widely read tale.Once upon a time，people hated the book because it struck them as rude.Twain himself wrote that those who banned the book considered the novel “trash and suitable only for the slums(贫民窟)．”More recently the book has been attacked because of the character Jim，the escaped slave，and many occurences of the word nigger.(The term Nigger Jim，for which the novel is often severely criticized，never appears in it.)
But the attacks were and are silly—and miss the point.The novel is strongly antislavery.Jim's search through the slave states for the family from whom he has been forcibly parted is heroic.As J．Chadwick has pointed out，the character of Jim was a first in American fiction—a recognition that the slave had two personalities，“the voice of survival within a white slave culture and the voice of the individual：Jim，the father and the man.”
There is much more.Twain's mystery novel Pudd'nhead Wilson stood as a challenge to the racial beliefs of even many of the liberals of his day.Written at a time when the accepted wisdom held Negroes to be inferior(低等的)to whites，especially in intelligence，Twain's tale centered in part around two babies switched at birth.A slave gave birth to her master's baby and，for fear that the child should be sold South，switched him for the master's baby by his wife.The slave's lightskinned child was taken to be white and grew up with both the attitudes and the education of the slaveholding class.The master's wife's baby was taken for black and grew up with the attitudes and intonations of the slave.
The point was difficult to miss：nurture(养育)，not nature，was the key to social status.The features of the black man that provided the stuff of prejudice—manner of speech，for example—were，to Twain，indicative of nothing other than the conditioning that slavery forced on its victims.
Twain's racial tone was not perfect.One is left uneasy，for example，by the lengthy passage in his autobiography(自传)about how much he loved what were called“nigger shows”in his youth—mostly with white men performing in blackface—and his delight in getting his mother to laugh at them.Yet there is no reason to think Twain saw the shows as representing reality.His frequent attacks on slavery and prejudice suggest his keen awareness that they did not.
Was Twain a racist？Asking the question in the 21st century is as wise as asking the same of Lincoln.If we read the words and attitudes of the past through the“wisdom”of the considered moral judgments of the present，we will find nothing but error.Lincoln，who believed the black man the inferior of the white，fought and won a war to free him.And Twain，raised in a slave state，briefly a soldier，and inventor of Jim，may have done more to anger the nation over racial injustice and awaken its collective conscience than any other novelist in the past century.How do Twain's novels on slavery differ from Stowe's?
| A．Twain was more willng to deal with racism. |
| B．Twain's attack on racism was much less open. |
| C．Twain's themes seemed to agree with plots. |

| B．The slave's voice was first heard in American novels. |
| C．Jim grew up into a man and a father in the white culture. |
| D．Twain suspected that the slaves were less intelligent. |
The story of two babies switched mainly indicates that________.
| A．slaves were forced to give up their babies to their masters |
| B．slaves' babies could pick up slaveholders' way of speaking |
| C．blacks' social position was shaped by how they were brought up |
| D．blacks were born with certain features of prejudice |

| D．Twain's works should be read from a historical point of view. |
If cars had wings，they could fly and that just might happen，beginning in 2012.The company Terrafugia，based in Woburn，Massachusetts，says it plans to deliver its carplane，the Transition，to customers by the end of 2012.
“It's the next ‘wow’ vehicle，” said Terrafugia，vice president Richard Gersh.“Anybody can buy a Ferrari，but as we say，Ferraris don't fly.”
The carplane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving.A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies，although it is both.The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble of trying to find another mode of transportation to get to and from airports：you drive the car to the airport and then you're good to go.When you land，you fold up the wings and hit the road.There are no expensive parking fees because you don't have to store it at an airport—you park it in the garage at home.
The carplane is designed to fly primarily under 10,000 feet.It has a maximum takeoff weight of 1,430 pounds，including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(边缘的) conditions.
The Transition's price tag：$194,000.But there may be additional charges for options like a radio，transponder or GPS.Another option is a fullplane parachute.
“If you get into a very awful situation，it is the necessary safety option，”Gersh said.
So far，the company has more than 70 orders with deposits.“We're working very closely with them，but there are still some remaining steps，” Brown said.We can learn from the first paragraph that ________.
| A．carplanes will be popular in 2012 |
| B．people might drive a carplane in 2012 |
| C．both the Transition and the Ferrari can take off and land |
| D．Richard Gersh is the vice president of Massachusetts |
It takes the carplane one minute to ________.
| A．fold and unfold its wings |
| B．unfold wings for flying |
| C．land in the airport |
| D．meet flying safety regulations |
According to the passage，which of the following is NOT true?
A．The carplane needs a runway to take off and land.
B．To meet aircraft regulations，the company has been working with FAA.
C．The carplane may fly as high as normal planes.
D．People can park the carplane in the garage at their home.The underlined word “it” in the last but one paragraph refers to ________.
| A．the radio |
| B．the transponder |
| C．the GPS |
| D．the fullplane parachute |
Want to find Bigfoot? Matt Moneymaker, president of Animal Planet's Finding Bigfoot, says the creatures have been seen in every state but Hawaii.
Redwoods State Park, California
With its towering redwoods and thick forest, it's hard to beat the atmosphere at this Northern California park.Moneymaker recommends taking a walk along the Smith River on Howland Hill Road.“We heard of lots of different sightings and sounds in there，”he says.“I've found tracks crossing that road.”7074657335.
SalmonHuckleberry Wilderness, Oregon
You don't have to go far to find Bigfoot.This area 20 miles east of Portland in the Mount Hood National Forest is prime spotting territory.Bigfoot apparently has a sweet tooth and goes ape for huckleberries, which grow in the area.Scores of campers have been scared off by noises and have had rocks thrown at them.5036681700.
Valles Caldera National Preserve, New Mexico
The high density of deer attracts Bigfoot to this place.The creatures may use the park's mountainous lookouts to watch over deer in spring.Even when there's no wind, dead trees often topple mysteriously, with their roots above the earth.“They let you know that they're there.”5056613333.
Bird Mountain Wildlife Management Area, Vermont
This prominent mountain peak outside the town of Rutland has had its share of activity, including a trailcam picture famous in Bigfoot circles of what appears to be a female one carrying her offspring (后代). Centuries ago，American Indians reported seeing an apelike creature and，more recently, hikers say that they have come upon a Bigfoot.8007568880.

Urbanization
(2013·高考北京卷)Until relatively recently，the vast majority of human beings lived and died without ever seeing a city.The first city was probably founded no more than 5,500 years ago.__ __In fact，nearly everyone lived on farms or in tiny rural (乡村的) villages.It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.
Britain was only the beginning. __The process of urbanization—the migration (迁徙) of people from the countryside to the city—was the result of modernization，which has rapidly transformed how people live and where they live.
In 1990，fewer than 40% of Americans lived in urban areas.Today，over 82% of Americans live in cities.Only about 2% live on farms.__ __
Large cities were impossible until agriculture became industrialized.Even in advanced agricultural societies，it took about ninetyfive people on farms to feed five people in cities._ _Until modern times，those living in cities were mainly the ruling elite(精英) and the servants，laborers and professionals who served them.Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.
Over the past two centuries，the Industrial Revolution has broken this balance between the city and the country. _Today，instead of needing ninetyfive farmers to feed five city people，one American farmer is able to feed more than a hundred nonfarmers.
| A．That kept cities very small. |
| B．The rest live in small towns. |
| C．The effects of urban living on people should be considered. |
| D．Soon many other industrial nations became urban societies. |
E．But even 200 years ago，only a few people could live in cities.
F．Modernization drew people to the cities and made farmers more productive.
G．Modern cities have destroyed social relations and the health of human beings.
