Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds. A new study suggests that warmer waters could make their numbers dwindle.
Most king penguins live on the Crozet Archipelago, a group of islands in the Indian Ocean, about 1,000 miles north of Antarctica. After the penguin chicks are born in November (which is summer in the Southern Hemisphere), both parents spend 4 months collecting fish to feed their children. When the fish move to deeper waters in March, the adults leave their chicks alone for months. They swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood, such as squid, to add their own energy stores. In October, nearly a year after their chicks are born, the parents return to feed and finish raising them.
Scientists from the French National Center for Scientific Research (CNRS) in
Ocean surface temperatures vary from year to year. And former research had shown that fewer squid, fish and other creatures grow when the water is warmer. Le Maho suspected that this drop in the food supply would make it harder for adult penguins to survive the tough times ahead. King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend could cause big trouble for a bird that depends on cold and ice.

| A. A sense of humour is not an inborn ability. B. A sense of humour can be developed in our life. C. A sense of humour helps us from several aspects. D. A sense of humour means more than telling jokes. E. A sense of humour can be expressed in many ways. F. A sense of humour helps people to better enjoy life. |
【小题2】Many people mistakenly believe that we are born with a sense of humour. They think that when it comes to a sense of humour. “Either you have got it or you don’t.” This is
false! What is true, however, is that the ability to laugh and smile is actually something we are born with. For example, we laugh when we are tickled under the arm, even without thinking about how to react.
【小题3】The parts of the brain and central nervous system that control laughing and smiling are mature at birth in human infants, but that is not the same thing as having a sense of humour. (After all, when a baby laughs in his small bed we don’t rush over and say, “That kid has a great sense of humour!”) Your sense of humour is something you can develop over a lifetime. Don’t be nervous before others and try to laugh at yourself-then you will make them laugh too.
【小题4】Humour includes a lot more than laughing and joke telling. Many people worry needlessly that they do not have a good sense of humour because they are not good joke tellers. More than jokes, a sense of humour requires being willing and able to see the funny side of life’s situations as they happen. In fact, one of the best definitions（定义）of a sense of humour is “the ability to see the nonserious element in a situation.”
【小题5】There may be a thousand different ways to express your sense of humour, but joke telling is only one of those ways. As more is discovered about how humour benefits our life, more people will be able to see and enjoy the humour when they are in a difficult situation. Life depends on air, food and water, but it is made easier to live with a good sense of humour. 查看习题详情和答案>>
I first visited hutong as part of a tourist group several years ago. We rode on a trishaw（脚踏三轮车） with a guide explaining the history, architecture and lifestyle of the local inhabitants.
Having visited the "must-sees" of Beijing, like the Forbidden City, the Temple of Heaven, the Drum Tower and the Summer Palace, going into the hutong home of some famous ancient families gave the “Beijing experience” a human element.
My curiosity has sharpened over the years from reading about them at every opportunity. During the preparation for the Olympics I was eager to learn that some siheyuan courtyards in hutong were turned into accommodations（食宿） for visitors. I wished to stay in one someday.
Preparing for a recent trip to the capital, I eagerly sought one out. On my limited teacher’s salary, I settled on an affordable option, though I looked longingly at the more upscale courtyard accommodations.
As usual, I ended up having something closer to a true experience. A real family still lives in the courtyard, which is closer to the original. The rooms all opened into the central courtyard. Flowers were blooming, beans and peas were climbing up the bamboo fence, and the cat was napping in the sun. Every day after exploring the city, I'd hurry back to the hutong, take a quick shower and join the cat – snoozing（小睡） in a bamboo-made chair with a book ready nearby.
As the other guests came back we’d greet one another. There was a mother and young daughter from France, a guy from Canada, a mother and teenage daughter from the Netherlands, a teacher from England and several guests from various parts of China.
Coming and going through the narrow alleys（小巷） of the hutong, the residents would smile and give cheery “ni hao” （hello）. Laughing children were playing under the watchful eyes of the neighbors. I felt right at home in this friendly neighborhood.
The main idea of the passage is about ______________.
A. hutong days realize my desires to live local life
B. Trishaw is the only way to visit the hutong
C. living in the hutong with other visitors
D. exploring the deeper of Beijing
When did the author have the idea to visit Beijing hutong?
A. As early as he was a little child
B. when he was reading the text books at school
C. during the preparation for the Olympics
D. the author doesn’t mention it specifically
The underlined word “upscale” in the fourth paragraph means _________.
A. inexpensive B. high-class C. appropriate D. secondary
What is the impression of the author about the people in hutong?
A. They came from all over the world.
B. They all wanted to enjoy the old life of Beijing.
C. They are living together in harmony.
D. They are living in a heavenly peace life.

Excused from recycling（回收利用） because you live in a high rise with a rubbish chute（垃圾道）? You won't be for long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .
In Shantzis' Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal, and other rubbish to go into separate boxes.
The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials （as well as for unrecyclables）. At the press of a button, a microcomputer locks all other floors' chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables
Sorting（分类） recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective.
57．The purpose in writing this text is _________.
A．to encourage people to recycle their rubbish
B．to introduce a recycling system for high rises

D．it won't be long before you'll have to recycle your rubbish
59．Before dropping rubbish into the chute you have to ___________
A．lock the other floors' chute doors
B．check if the container is full
C．press the correct button
D．break up the rubbish
60．The biggest advantage of this new system is that _________
A．it readuces the cost of recycling
B．it saves time and space
C．it saves money for people living in high rises
D．it makes better use of the existing recovery equipment
His first successful fight was for the equal rights of black people in South Africa. Then, as the first black president, he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.
On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.
Mandela was born in a small village in South Africa in 1918. He was adopted by the chief of his tribe and could have been a chief himself and lived a happy country life.
But he refused to be a chief when his people lived under racial discrimination(歧视). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law, colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.
For his opposition to the system, Mandela was arrested and spent 27 years in prison. He was freed in 1990 and became the president of the country after the first election were held in which everyone could vote.
Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer and fought in the ring when he was young.
“Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat”, he wrote in his autobiography.
As a skillful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.
