A new study has found evidence of aggressive(富于攻击性的)behaviors 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. The women were also asked to complete a checklist of their children’s behaviors.
The researchers found that 43 percent of the boys and girls drank at least one daily serving of soda, 4 percent of the youngsters had four or more servings of soda to drink every day.
Shakira Suglia is with Columbia University’s Mailman School of Public Health in New York City. She worked on the study with researchers from the University of Vermont and Harvard University School of Public Health. She says they found that children who drank the most soda were more than two times as likely as those who drank no soda to show signs of aggression.
“For the children who consumed four or more servings of soft drinks per day, we see an association between aggressive behaviors, attention problems and withdrawn behaviors. ”
The aggressive behaviors included destroying possessions belonging to others, taking part in fights and physically attacking people.
Doctor Suglia says it’s not clear why young children who drink a lot of soda have behavior problems.
“We can’t prove that this is a direct cause and effect relationship, having said that, there are a lot of ingredients in soda, a lot of ingredients that have not been examined in relation to behaviors. ”
Earlier studies of young adults have found the highest sugar levels in those who carry weapons and show signs of negative social behaviors.

Special Bridges Help Animals Cross the Road
——Reported by Sheila Carrick
Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U. S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U. S. today. The main reason? Road kill.
“Ecopassages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These ecopassages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lions used the passage.
Builders of ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive th
rough an area with a lot of wildlife, look around. You might see an animals overpass!The writer uses the example of “ocelots” to show that _____________.
| A．wild animals have become more dangerous |
| B．the driving conditions have improved greatly |
| C．the measure for protecting wildlife fails to work |
| D．an increasing number of animals are killed in road accidents |
From the news story, we know an ecopassage is _____________.
| A．an underground path for cars |
| B．a fence built for the safety of the area |
| C．a bridge for animals to get over a river |
| D．a pass for animals to cross the road |
When the writer says that animals seem “to be catching on”, he means ___________.
| A．animals begin to realize the dangers on the road |
| B．animals begin to learn to use ecopassages |
| C．animals are crossing the road in groups |
| D．animals are increasing in number |
The writer asks visitors and drivers to look around when traveling because _________.
| A．wild animals may attack cars |
| B．wild animals may jam the road |
C．they may see w ild animals in the park |
| D．they may see wild animals on ecopassages |

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?”? He looked perturbed (不安). “Do you want to try it first?” he said. It didn’t quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it？” This made him look a bit insulted and I started to feel bad. “No, no. But you should try it,” he said encouragingly. “Compare it with the others. ”
I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.
But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out of my chosen camera from cupboard, show how it took excellent pictures of my fellow shoppers… and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.
Why do we think that new options still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.The shop assistant insisted that the writer should________.
| A．try the camera to see if there was anything wrong with it. |
| B．compare the camera he had chosen with the others. |
| C．get more information about different companies. |
| D．trust him and stop asking questions. |
What does the writer mean by “it would be worth half what I paid for it ”(paragraph 2)
| A．He should get a 50% discount. |
| B．The price of the camera was unreasonably high. |
| C．The quality of the camera was not good. |
| D．The camera would soon fall in value. |
The writer decided to try the model he had chosen because he________.
| A．knew very little about it. |
| B．didn’t trust the shop assistant |
| C．wanted to make sure the one he chose would be the best. |
| D．had a special interest in taking pictures of his fellow shoppers. |
It can be inferred from the passage that in the writer’s opinion__________.
| A．people waste too much money on cameras |
| B．cameras have become an important part of our daily life |
| C．we don’t actually need so many choices when buying a product |
| D．famous companies care more about profit than quality |
It’s hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy’s former top secret system of underwater listening devices across the oceans.
Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope(听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.The underwater listening system was originally designed _________________.
| A．to trace and locate enemy ships |
| B．to observe deep sea volcanic eruptions |
| C．to study the movement of ocean currents |
| D．to replace the global radio communications network |
The deep-sea listening system makes use of __________________.
| A．the ability of sound to travel at high speed |
| B．the top-level technology of focusing sounds under water |
| C．the unique characteristic of layers of ocean water in carrying sound |
| D．low-frequency sounds traveling across different layers of water |
What can we infer from the passage?
| A．New radio devices are developed for tracking the blue whales. |
| B．Blue whales are no longer endangered with the new system. |
| C．Opinions differ on the use of military technology. |
| D．Military technology has great potential in civilian use. |
What is the passage chiefly about?
| A．An effort to protect an endangered marine species. |
| B．The civilian use of a military detection system. |
| C．The exposure of a US Navy top-secret weapon. |
| D．A new way to look into the behavior of blue whales. |
New York: Staying positive through the cold season could be your best defence against getting ill, new study findings suggest.
In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help protect us from the common cold and other illnesses.
Researchers believe the reasons may be both objective----as in happiness improving immune, function----and subjective----as in happy people being less troubled by a sore throat or funny nose. "People with a positive emotional style may have different immune responses to the virus," explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe."
Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional trait itself had the effect.
For the new study, the researchers had 193 healthy adults complete standard measures of personality traits, self-perceived health and emotional "style." Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style.
The researchers gave them nasal(鼻的) drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, sneezing or congestion they had, while the researchers collected objective data, like daily mucus production. Cohen and his colleagues found that based on objective measures of nasal woes, happy people were less likely to develop a cold.Which is the best title for the passage?
| A．Stay Away From Being Negative |
| B．Positive or Negative, It’s Up To You |
| C．An Effective Medicine For Being Fit |
| D．Warm People Likely To Keep Cold Away |
According to Dr Cohen’s research, the reason why some people are unlikely to catch a cold is that ___________________.
| A．their cheerful mood benefits the immune system |
| B．they have developed a certain gene against flu virus |
| C．they are less likely to have s sore throat and funny nose |
| D．they have got a stronger self-confidence in their health |
The underlined word “disposition” (paragraph 2) probably means ________.
| A．character | B．day | C．future | D．occupation |
The passage is probably written for ___________________.
| A．medical students | B．lead authors | C．the public | D．the volunteers |
