WASHINGTON(Reuters)‑People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer (胰腺癌), an unusual but deadly cancer, researchers reported on Monday.

People who drank mostly fruit juice instead of sodas did not have the same risk, the study of 60,000 people in Singapore found.

“Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits,” said Mark Pereira of the University of Minnesota, who led the study.

“The high levels of sugar in soft drinks may be increasing the level of insulin(胰岛素) in the body, which we think contributes to pancreatic cancer cell growth,” President said in a statement.

Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and his colleagues said they followed 60,524 men and women in the Singapore—Chinese Health Study for 14 years.

Over that time, 140 of the volunteers developed pancreatic cancer. Those who drank two or more sweetened soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer.

Pereira said he believed the findings would apply elsewhere.

“Singapore is a wealthy country with excellent healthcare. Favorite pastimes(消遣) are eating and shopping, so the findings should apply to other western countries.” he said.

But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious.

“Although this study found a risk, the finding was based on a relatively small number of cases and it remains unclear whether it was a causal(因果的) connection or not.” Said Mayne, who serves on thee board of the journal, which is published by the American Association for Cancer Research.

Pancreatic cancer is one of the deadliest form of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34, 290 die of it.

1.We can infer from Pereira’s word that_________

A. the healthcare in Singapore should be greatly improved

B. 2 soft drinks a day are considered harmful to health

C. 87 out of 140 volunteers developed pancreatic cancer

D. sugar might not be the only cause of pancreatic cancer.

2.How does Susan seem to feel about the findings of the study?

A. Satisfied        B. Doubtful        C. Worried         D. Hopeful

3.The best title of the text might be_______

A. The Deadliest Forms of Cancer

B. Drink Fruit Juice Instead of Sodas

D. Sugary Soft Drinks Lead to Cancer

Drinking Water: Bottled or From the Tap（水龙头）?

In America, people will include a case or two of bottled water when buying the week's groceries（日用杂货）．When they are going to a soccer game or activity, it's common for them to grab a cold bottle of water out of the fridge with them．In fact, Americans buy more bottled water than any other nation in the world, about 29 billion bottles a year．

But all these plastic bottles use a lot of fossil fuels and pollute the environment．In order to make all the 29 billion bottles, producers use 17 million barrels of crude oil, which is enough to keep a million cars going for 12 months．

So why don't people drink water straight from the tap? Some people have a strong belief that bottled water is better than water out of the tap, but that's not necessarily true．In the US, the local governments make sure water from the tap is safe．There is also growing concern that chemicals in the bottles themselves may go into the water．

People love the convenience of bottled water．But maybe if they realized the problems it causes, they would try drinking from a glass at home or carrying water in a reusable steel container instead of plastic．

Some argue that plastic bottle recycling can help．Recycled bottles can be turned into items like carpeting or clothing．Unfortunately, only one in six bottles is recycled．The rest make it to landfills（垃圾填坦场） or end as trash in other places．Plastic bottles take hundreds of years for them to disintegrate．

Water is important for you, so keep drinking it．But think about how often you use water bottles, and see if you can make a change．

And yes, you can make a difference．Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours．

1.How many cars can be kept going for a year by the crude oil used to make 29 billion bottles?

2.Why do Americans prefer bottled water?

3.What does the underlined word "disintegrate" in the fifth paragraph probably mean^

4.The author's intention of writing this passage is to recommend Americans

A new study has found evidence of aggressive (攻击性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.

The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.

Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.

“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”

The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.

The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.

Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.

It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.

The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centers are set up. In their study, the researchers examined groups of nine-month-old babies in new South Wales and Britain.

And they came across astonishing results—it was found that infants had “social brains” and focused not just on their mothers but on social 1ife in groups as well,

“They communicate with more than one baby at once，and show jealousy and generousness，”said Professor Bradley．

He added，“They develop their own meanings through group interaction，they notice if a group member is behaving differently and they take on roles，such as leaders and followers．”

“A baby who has a depressed mother tends to be withdrawn(内向的)，but put that same baby in a group of its peers(同龄人)and they behave and interact like any other baby．”

It was the first all-baby group study ever to be conducted．“Most studies of babies concentrate on the infant-mother relationship，assuming that is the single foundation for mental health．but babies are constantly involved with groups of people other than their mothers：fathers，siblings，grandparents and those taking care．Therefore。the ‘mother-baby approach’ needs to be combined with a‘ group approach’．”said Bradley．

Phoebe Christison ，a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west．said she often noticed what appeared．to be emotional attachments developed between toddlers．

She said，“Joel(10 months)and Isabella (11months)always like to hold hands when they sit in their high chairs and eat．And babies definitely show jealousy．They push and touch each other，and copy what the other is doing．”

1.A baby who has a depressed mother ____  ．

A．tends to be a follower

B．also enjoys group interaction

C．has poor social ability

D．pays more attention to its mother

2.What can be inferred from the result of this study?

A．Babies are affected by groups more than by their mothers．

B．There’s no need of child-care centers at a11．

C． Adults should include babies when having social activities．

D．The normal infant-mother bond alone isn’t enough for the good mental health for babies．

3.The underlined word “toddlers” in Para．8 can be replaced by_________

A．adults            B．infants            C．peers            D．groups

4.The example given in the last paragraph proves that a baby________ .
