It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic
variations(变异). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for th
e first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.
Lewis and his co-workers carried out their study by videotaping(录像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”The writer’s purpose in writing the text is to _________.
| A．show the relationship between parents and children |
| B．teach parents ways to keep order at the dinner table |

TOKYO, Japan (AP) – Japan is very serious about robotics (机器人技术). If the androids are going to fit in, they probably need to learn the Japanese custom of serving tea. Fortunately, researchers at the University of Tokyo are exploring just that. In a show this week, an android（有人特点的）with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup. Then another robot on wheels delivered the cup of tea in an experimental room that has sensors(感应器)embedded in the floor and sofa as well as cameras on the ceiling, to simulate（模仿）life with robot technology.
“A human being may be faster, but you’d have to say ‘Thank you,’” said University of Tokyo professor Tomomasa Sato. “That’s the best part about a robot. You don’t have to feel bad about asking it to do things.”
Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden（卧床不起的）. Already, monitoring technologies, such as sensors that automatically turn on lights when people enter a room, are becoming widespread in Japan.
The walking, child–size Asimo from Honda Motor Co. greets people at showrooms. NEC Corp. has developed a smaller companion robot on wheels called Papero. A robot available since 2004 can entertain the elderly and others in need of companionship.
Sato says his experimental room is raising awareness about privacy questions that may arise when electronic devices（设备）monitor a person’s movements down to the smallest detail.
On the bright side, the tea – pouring humanoid has been programmed to do the dishes.What is the best title of this passage?
| A．“Thank You” Will Never Be Needed in Japan |
| B．Monitoring Technologies Are Widespread in Japan |
| C．Robot Is Designed to Care for the Elderly. |
| D．Robot technologies are widespread in Japanese daily life. |
The underlined word “embedded” in the first paragraph probably means .
| A．fixed | B．established | C．settled | D．rooted |
According to Professor Sato, .
| A．the robot serves tea much faster than a human being |
| B．the robot does anything like human beings |
| C．tea – serving robot helps to form laziness of the aging society |
| D．tea – serving robot doesn’t need any reward for the service |
Which of the following statements is NOT true?
| A．A robot can imitate people to complete complicated tasks. |
| B．A robot has been programmed to clean the dishes. |
| C．All the problems in the aging society can be solved by robots. |
| D．The number of aging people is increasing rapidly in Japan. |
We can infer from the passage that .
| A．people are afraid of being monitored by robots. |
| B．the technology of robots has been highlighted（强调） in Japan. |
| C．robots can completely take the place of human beings. |
| D．people’s privacy should be strictly protected |
"Beating is a sign of affection, cursing (骂）is a sign of love."
Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been—but experts say they still ring true.
Today, it seems, Chinese parents are more likely to send their children to pre-college military academies in the United States in the hope that some tough love will pave the way tosuccess.
"Good education doesn't mean letting your child enjoy privileges, especially our boys," said Song Wenming, an entrepreneur(企业家）in Jinhua, East China's Zhejiang province." They should be raised in tough conditions to know what to fight for in the future."
In August, Song sent his 17-year-old son to Valley Forge Military Academy (VFMA) in Pennsylvania. And he is far from alone, even though it takes a lot of money - around $48,000 per year —to send a child to a strict military school.
Statistics shows that an increasing number of Chinese students have been registering with such academies.
A few years ago, there were no Chinese students at Valley Forge. Today, there are 28."All of the Chinese students at Valley Forge came from wealthy families, some of them were spoiled," said Jennifer Myers, director of marketing and communications at the school.
Song's only son, Song Siyu, had a rocky start during his first six weeks at the school. The teenager said he went to the school voluntarily but did not expect it to be as difficult.
Now, three months later, he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision. He can even take criticism, no matter how unreasonable.
"The training is hard but I know it is good for self-development of individuals," said Song Siyu.'The endless training and scolding are just ways to build up our character, they are not personal."
But his enthusiasm is not universal. Ten of the 13 Chinese students who joined the academy this year have transferred to other schools.
But for those who stick with it, there is a reward for all the hard work.From the second paragraph, we can know the old Chinese saying _____.
| A．is out of date in modern times. |
| B．is disagreed by rich parents. |
| C．is still worth trusting. |
| D．is deeply believed by better educated parent. |
The underlined sentence means that _____
| A．Song sent his only son to military school, so he feels lonely. |
| B．Song is the only one who sends his child t to military school. |
| C．There are other people sending their children to military school besides Song. |
| D．The fee of the military school is so high that only Song can afford it. |
Song Siyu got some achievements in the military school except _____.
| A．taking a bath in a short time | B．having his meal with his eyes closed |
| C．taking unreasonable criticism | D．improving his character |
How many Chinese students are there at Valley Forge before this year?
| A．10 | B．13 | C．15 | D．25 |
Which of the following can be inferred from the passage?
A. It's likely that more and more Chinese students will attend VFMA.
B. Most Chinese parents approve of educating their children by beating and cursing nowadays.
C. Song Siyu had no difficulty in adjusting to the life at VFMA.
D. Most Chinese students support the way of education at VFMA.
Philip was a nine-year-old boy in a Sunday school class of 8-year-old girls and boys. Sometimes the third graders didn’t welcome Philip into their group and usually tricked him. This was not because he was older, but because he was “different”. You see, Philip suffered from a condition called Downs’s Syndrome. This made him “different”, with his facial characteristics, slow responses and mental problems.
One Sunday after Easter, the Sunday school teacher gathered some plastic eggs that pulled apart in the middle. The teacher gave one to each child. On that beautiful spring day, the children were to go out and discover for themselves some symbol of “new life” and place it inside the plastic eggs.
After the children returned to the classroom, the teacher opened their eggs one by one, asking each child to explain that symbol of “new life”. The first opened egg contained a flower. Everyone cheered. In another was a butterfly…. When the teacher opened the last egg, it was empty. “That’s stupid,” said someone. The teacher felt a pull at his shirt. It was Philip. Looking up, Philip said, “It’s mine. I did it. It’s empty. I have new life, because the tomb is empty.” Not a sound was heard in class at all. From that day on, Philip became a real part of the group. They welcomed him, and whatever made him different was never mentioned again.The underlined word “condition” in the first paragraph probably means ________.

Roman Pantheon （万神殿） is one of the greatest achievements of the ancient Romans. The ancient Romans were good architects and they built many wonderful buildings. Another good example of a Roman architectural style is the Roman Coliseum, which is a large building used for public sports events or entertainment. The Roman architectural style has been borrowed by many of the western countries.
The architecture of Pantheon is unique to Rome. In Latin and Greek, pantheon means "Temple of all the Gods". Marcus Agrippa built the original Pantheon in 27 BC. But the Pantheon built by Agrippa was completely destroyed in 80 AD when a fire broke out. The Roman Pantheon that is visited by many tourists today was rebuilt in 125 AD by the Roman emperor Hadrian. Hadrian's architects followed the exact design of Marcus Agrippa. Historians believe that the Pantheon was a place of worship(崇拜) because it housed all the gods and goddesses of the ancient Romans.
The Pantheon of Rome is an amazing example of ancient Roman architecture. This building has been in use for over 2000 years. The Roman Pantheon is famous for its design, size. The most unbelievable feature of this building is its huge concrete dome(圆顶). The Pantheon’s dome was thought to be the largest, until recent times.
Phocas, the Byzantine Emperor presented the Roman Pantheon to Pope Boniface IV to save it from the destruction. In 609 AD, it was turned into a church. During Papal rule, it was used as a burial ground (坟场) for kings and other famous people. There are tombs of Raphael (a painter), King Victor Emmanuel II, King Umberto I and many more in the Pantheon.
Some of the buildings that were constructed on the model of the Roman Pantheon are The Rotunda - University of Virginia, Low Memorial Library - Columbia University, Grand Auditorium - Tsinghua University, Jefferson Memorial - Washington D.C. and Duomo - Florence.From the first paragraph, we can learn that _______.
