Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.
Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.
“What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.
May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.
“The fact that subtle(微妙的)differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.

Singles Day falls on every November 11th, and as the name indicates, this relatively new holiday is one specially for people who are still living the single life. I was a bit surprised when I googled “Singles Day” on the Internet, to find that China is the only country in the world that has set up a special day for singles to celebrate their lives.
An old story goes that once there were four single men, leading very boring lives. None of them were married, or had lovers, or did anything exciting. They just sat around all day and played Mahjong. One day they played Mahjong from 11 in the morning until 11 at night. During the game, no matter who won, the winning card was always the “four columns” card (the card shows four independent, parallel columns in two lines). Even more of a coincidence, it was Nov. 11. In order to remind them of the day, they nicknamed it Singles Day.
Singles Day was first celebrated at various universities in Nanjing, capital city of Jiangsu Province during the 1990s. These college students carried their university tradition into society after they graduated. Singles Day is now a special day for all.
The main way to celebrate Singles day is to have dinner with your single friends, but it’s important that each person pay their own way to show their independence. People also hold “blind date” parties in an attempt to say goodbye to their single lives.
For breakfast on Singles Day, singles often eat four youtiao (deep-fried dough sitcks) representing the four “ones” in “11.11” and one baozi (steamed stuffed buns) representing the dot in between.
Many singles also choose to say goodbye to their single lives on the day. Many attend “blind date” parties and many people choose to marry on this day. In addition to meaning “single”, the four “ones” of the date can also mean “only one” as in “the only one for me”. Some people will use this date and this meaning to tell their special someone that they are the only “one” in their heart.
45. Which of the statement is TRUE according to the passage?
A. Singles Day has a long history.
B. Only men celebrate Singles Day.
C. Singles Day is only celebrated in China.
D. Students in Nanjing University started Singles Day.
46. People celebrate the festival mainly by .
A. playing MahjongB. having dinner
C. getting marriedD. hanging out with friends
47. What is the best title of the passage?
A. Singles Day
B. Four Single Men’s Singles Day
C. University Culture on Singles Day
D. Symbolic Food on Singles Day

Long bus rides are like television shows. They have a beginning, a middle, and an end — with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by (滑过) outside the bus window. Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of “You Need It! Buy It Now!”?
The beginning of the ride is comfortable and somewhat exciting, even if you’ve traveled that way before. Usually some things have changed — new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly careless or daring, the ride can be as thrilling as a horror story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting, but you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you’ve sat with your legs crossed, with your hands in your lap, with your hands on the arm rests — even with your hands crossed behind your head. The end comes just at the right time. There just no more ways to sit.

Children are being indirectly affectly by the impact of the recession (经济衰退) on their parents, the Children’s society warns.
The chief executive of the Children’s Society, Bob Reitemeier, said that children were “on the front of recession”. He said the recession made it even more important to try to end child poverty.
The answers suggest children from poorer backgrounds are more likely to be affected, but over a third of children across all backgrounds said they were aware that the recession was worrying their parents.
Fifteen-year-old Patricia said her family felt the impact of the recession on their everyday budget(预算). “We have to save up our money and do not spend it so much on unnecessary things,”she said.
Those questioned appeared to have great awareness of the economic crisis, which, unsurprisingly, was higher among the older children. But around 15% said they hadn’t been affected by it.
Recent figures showed that in 2007 there were 850,000 young people with no particular occupation. An official from the government said it was so “disappointing” that some young people were concerned about the economy.
Parents are clearly best placed to talk to their children about their worries, but schools also play an important role in teaching young people the skills they need to become healthy, happy and confident individuals.
68.Which of the following is true?
A. It is more important to try to end child poverty in the recession.
B.Children from poorer areas are less likely to be affected.
C.All the children questioned are worried about the economy.
D.That some young people are worrying about the economy is “good news”.
69.What does the underlined word “it” refer to in Paragraph 5?
A. The poorer background. B.The impact of the recession.
C. Everyday budget. D.The government.
70.What’s the main idea of the passage?
A. Many children are concerned about the recession.
B.Children are being directly affected by the recession.
C.The recession affected children indirectly.
D. Schools play an important role in teaching young people how to become healthy, happy and confident individuals.

Every night for a year, Neil Simons quietly went out of his house. He wanted to “talk” to an owl (猫头鹰)settling for the night at the end of his garden. He made owl cries like a real wild owl and was happy to hear the bird “hooting (大声叫嚣)” back to him.
Last year Fred Cornes moved in next door. He heard an owl hooting and answered back. For 12 months the neighbors got into the back gardens of their homes, thinking they were talking with nature.

Some say everyday miracles(奇迹) are predestined(注定的)----the right time for the appointed
meeting. And it can happen anywhere.
In 2001, 11-year-old Kevin Stephan was a bat boy for his younger brother's Little League team in
Lancaster, New York. It was an early evening in late July. Kevin was standing on the grass away from the plate, where another youngster was warming up for the next game. Swinging his bat back and forth, giving it all the power an elementary school kid could give. The boy brought the bat back hard and hit Kevin in the chest. His heart stopped.
When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid.
Penny Brown hadn't planned to be there that day, but at the last minute, her shift(换班)at the hospital had been changed to see her son’s performance. She was given the night off. Penny bent over the senseless boy, his face already starting to turn blue, and giving CPR, breathing into his mouth and giving chest compressions. And he revived in the end.
After his recovery, he became a volunteer junior firefighter, learning some of the emergency first-aid
techniques that had saved his life. He studied hard in school and was saving money for college by working as a dishwasher in a local restaurant in his spare time.
Kevin, now 18, was working in the kitchen when he heard people screaming, customers in confusion,
employees rushing toward a table. He hurried into the main room and saw a woman there, her face turning blue, her hands at her throat. She was choking.
Quickly Kevin stepped behind her, wrapped his arms around her and clasped his hands. Then, using
skills he'd first learned in Scouts. The food that was trapped in the woman's throat was freed. The color began to return to her face.
"The food was stuck. I couldn't breathe," she said. She thought she was dying. "I was very frightened."
