How is it that siblings (兄弟姐妹) can turn out so differently? One answer is that in fact each sibling grows up in a different family. The firstborn is, for a while, an only child, and therefore has a completely different experience of the parents than those born later. The next child is, for a while, the youngest, until the situation is changed by a new arrival. The mother and father themselves are changing and growing up too. One sibling might live in a stable and close family in the first few years; another might be raised in a family crisis, with a disappointed mother or an angry father.

Sibling competition was identified as an important shaping force as early as in 1918. But more recently, researchers have found many ways in which brothers and sisters are a lasting force in each others’ lives. Dr. Annette Henderson says firstborn children pick up vocabulary more quickly than their siblings. The reason for this might be that the later children aren’t getting the same one-on-one time with parents. But that doesn’t mean that the younger children have problems with language development. Later-borns don’t enjoy that much talking time with parents, but instead they harvest lessons from bigger brothers and sisters, learning entire phrases and getting an understanding of social concepts such as the difference between “I” and “me”. 

A Cambridge University study of 140 children found that siblings created a rich world of play that helped them grow socially. Love-hate relationships were common among the children. Even those siblings who fought the most had just as much positive communication as the other sibling pairs.

One way children seek more attention from parents is by making themselves different from their siblings, particularly if they are close in age. Researchers have found that the first two children in a family are typically more different from each other than the second and third. Girls with brothers show their differences to a maximum degree by being more feminine than girls with sisters. A 2003 research paper studied adolescents from 185 families over two years, finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents.

First lady Michelle Obama turns 50 on Friday, Jan. 17, 2014.

Michelle Obama has spent the first half-century of her life breaking barriers and checking off a series of firsts. Now, as she reaches her milestone birthday Friday, the nation will be watching to see in what other areas she will leave her mark.

Five years after moving into the White House, and without a re-election campaign to worry about, she has more room to relax in her role and, political watchers say, possibly become more vocal (声音的) on political issues in the three years left in office.

So far, critics have complained about Michelle’s silence on issues where they expected to hear her voice: Last year, at the start of her husband's second term, she disappointed advocates for tighter gun-control measures after she failed to push harder on the issue in response to the massacre (残杀) at Sandy Hook Elementary School in Newtown, Conn. She also disappointed some feminists (女权主义者) who wanted her to defend their causes instead of falling back on her self-described role as the nation’s “mom-in-chief.” Nor did she handle racial issues during her second term, as some had expected.

“The most important thing to remember is, whether you are black, white or Hispanic, you’re the first lady and the president of all the people in the United States. That’s a huge melting pot, so to reinforce (强化)that she's African American over anything else would not be wise,” said Anita McBride, who directs programming and national conferences on the legacies (遗产) of America’s first ladies and their historical influence at American University.

Valerie Jarrett, a top White House adviser and a close friend of the Obamas, said the first lady doesn't want to “spread herself too thin.”

“She really wants to have a maximum impact and to do that in fewer areas,” Jarrett told the Associated Press. “That, she said, “is better than trying to take on every single possible cause.”

But Robert Watson, a Lynn University professor, said he expects Obama to “go a little harder at issues” over the next several years. “Second-term first ladies usually feel more at ease to speak more forcefully about issues close to their heart,” he said.

Myra Gutin, a Ryder University communications professor and frequent lecturer on first ladies, said she expects Obama to continue making both of them a priority in her remaining years in the White House, given their success. Michelle launched the “Let’s Move” campaign in 2010. It in particular has gained widespread support, ranging from the National Football League to the Sesame Street franchise (特许), which even gave permission to the produce industry to use its licensed characters for free on fruits and vegetables.

“There’s no such thing as a traditional first lady, not anymore in this technology-filled world. Is Mrs. Obama cutting edge? Is she an activist? No. As first ladies go, I think she’s been politically careful because she does not want there to be a major flare-up that would require her husband to use his political capital to clean up,” she said. “But she’s not exactly just sitting in the White House pouring tea and having receptions, either.”

A. she didn’t put gun-control measures into effect

B. she failed some feminists to stand out to be a career woman

C. she didn’t solve some racial problems

D. she failed to voice her opinion on some issues

2.According to the professors or advisers, which of the following statements is NOT true?

A. It’s not wise to reinforce Michelle is African American over anything else.

B. It’s better for Michelle to have a maximum impact than to take on every possible cause.

C. It's expected for Michelle to go a little harder at issues.

D. It’s a tradition for first ladies to stay out of political issues.

3.What does the underlined phrase “spread herself too thin” in Paragraph 6 mean?

A. Try to do a lot of work at the same time.

B. Get very tired.

C. Try to improve physical fitness.

D. Move herself away from others.

4.In Paragraph 9, the campaign “Let’s Move” might be aiming to help people _______..

a. gain widespread support

c. have access to healthier foods

d. raise awareness about gun control

A. a, c        B. a, b        C. b, c        D. c, d

Driving a Car is not just handing controls and judging speed and distance, it requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制药), damaging eyesight, judgment and co-ordination（协调）,slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like a shower or having a cup of tea or coffee.
The present traffic ordinance states clearly that the limit of alcohol concentration is:
●50 milligrams of alcohol per l00ml of blood; or
●22 milligrams of alcohol per l00ml of breath; or
●67 milligrams of alcohol per l00ml of urine(尿液)
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any drive found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK﹩25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens (样本) far breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible, driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.
【小题1】The first paragraph is mainly about_____________.

Even if we have an extremely healthy diet and lifestyle, the human body is programmed to wear out at a maximum of about 120 years, and usually less. We all have a biological clock inside us which determines the moment when our organs cease to function properly. This is because our cells have stopped renewing themselves and our body can no longer repair itself. This is also the moment when we are more likely to begin to suffer from the diseases of old age such as arthritis and Alzheimer’s. However, rapid advances in DNA research are beginning to throw light on the secrets of the ageing process. By the end of this century we could literally have the power of life over death.
Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to live indefinitely. The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing.
Another new area of research involves the oxidation（氧化） theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young.
Perhaps the most immediate advance we are likely to see in the battle to halt（停止）the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing injured bones or even organs like livers and kidneys with ones “grown” in laboratories. By 2050 perhaps every organ in the body, except the brain, will have become commercially available. Recent experiments also show that it may one day be possible to “grow” new organs inside our body to replace worn-out ones, something which lizards and alligators already do.
Suddenly immortality（不死，不朽） seems within reach. We can begin to imagine a future where we are born, we grow to maturity, but we never grow old and die. But do we really want to live forever?

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 car-plane, the Transition, to customers by the end of 2012.
“It’s next ‘wow’ vehicle,” said Terrafugia vice president Richard Gersh. “Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car-plane 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 from 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 hold 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 car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Thrrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的) conditions.
The Transition’s price tag: $194,000. But there may be additional charges for options like a radio, , a transponder or a GPS. Another option is a full-plane 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.
