Salt plays an important role in our daily diet. Even a small reduction(减少) in salt in the diet can be a big help to the heart. A new study used a computer model to predict -how just three grams less a day would affect heart disease in the United States.
The result: Thirteen percent fewer heart attacks. Eight percent fewer strokes（中风）. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings. Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodiu(钠), which is how foods may list their salt content．
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference(干预).
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows that the calorie information on the menu can influence what parents order for their children. Ninety-nine parents of three to six year olds took part. Half had calories between the two groups for foods that the parents would have chosen for themselves. McDonald's menus clearly showing how many calories were in each food. Parents given the counts chose an average of one hundred two fewer calories when asked what they would order for their children. Yet there was no difference in calories between the two groups for foods that the parents would have chosen for themselves.
Study leader Pooja Tandon says even small calorie reductions on a regular basis can prevent weight gain over time. The study was published in the journal Pediatrics.

Newborns begin to develop language skills long before they begin speaking. And, compared to adults, they develop these skills more quickly. People have a hard time learning new languages as they grow older, but babies have the ability to learn any language easily.
For a long time, scientists have tried to explain how such young children can learn the complicated grammatical rules and sounds of a language. Now, researchers are getting a better idea of what’s happening in the brains of the tiniest language learners. This new information might help kids with learning problems as well as adults who want to learn new languages. It might even help scientists who are trying to design computers that can communicate like people do.
Most babies go “ma ma” by 6 months of age, and most children speak in full sentences by age 3. For many years, scientists have wondered how the brains of young children figure out how to communicate using language. With help from new technologies, scientists are now finding that babies begin life with the ability to learn any language. They get into contact with other people, listen to what they say and watch their movements very closely. That is why they quickly master the languages they hear most often.
Studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world. Starting at around 6 months old a baby’s brain focuses on the most common sounds it hears. Then, children begin responding only to the sounds of the language they hear the most.
In a similar way older babies start recognizing the patterns that make up the rules of their native language. For example, English children who are about 18 months old start to figure out that words ending in “-ing” or “-ed” are usually verbs, and that verbs are action words.
1.The new research in the second paragraph can be helpful in _____.
A. finding successful language learners
B. teaching kids with learning problems
C. designing human-shaped computers
D. improving babies’ language ability
2.The researchers found out that babies learn a language mainly by _____.
A. repeating the words of other people
B. remembering the full sentences they hear
C. hearing and closely watching others speak
D. figuring out the meaning of different sounds
3.The purpose of the text is to _____.
A. discuss
B. educate
C. inform
D. entertain
My roommate Lily was well organized, while I was not. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签) everything. I always looked for everything. Over time, Lily got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

LONDON—Terror struck in the heart of London on Thursday as explosions ripped through three subway trains and blasted(炸开)the roof off a crowded red double-decker bus. At least 37 people were killed and more than 700 wounded in the deadliest attack on the city since the blitz(闪电战)in World War II.
British Prime Minister Tony Blair blamed Islamic extremists and said the bombings were designed to coincide with the opening in Scotland of a G-8 summit of the world’s most powerful leaders. Foreign Secretary Jack Straw said the bombings—which came the day after London won the bid to host the 2012 Olympics--- have the “hallmarks(特点)of an al-Qaida-related attack”.
Trapped passengers in the Underground railway threw themselves on the floor, some sobbing. As subway cars quickly filled with smoke, people used their umbrellas try to break the windows so that they could get air. Passengers emerged from the Underground covered with blood and soot(黑烟). On the street, in a light rain, buses ferried the wounded, and doctors used a hotel as a hospital.
“I didn’t hear anything, just a flash of light, people screaming, no thoughts of what it was. I just had to get out of the train,” said subway passenger Chris Randall, 28, who was hospitalized with cuts and burns to the face, the legs and hands.
“It was chaos(混乱),” said Gary Lewis, 32, evacuated(撤离)from a subway train at King’s Cross station. “The one haunting(萦绕)image was someone whose face was totally black( with soot) and pouring with blood.”
Police said there had been no warning and that the blasts at three subway stations went off within 26 minutes, starting at 8:51 a.m. in an Underground train just outside the financial district. Authorities initially blames a power failure but realized it was a terror attack after the bus bombing near the British Museum at 9:47 a.m.—less than an hour after the first explosion.

Last week our class voted on how to do for you class outing: visit the Singapore Zoo and go to the Night Safari(夜间动物园). We girls wanted to go to the zoo, but since we are in minority, we lost to the boys, that all wanted the safari. We got the admission rate for the students, which was great since I still had not enough money to buy a brochure about the park as well as something at the souvenir shops. The safari was scary(吓人的)but real fun. As we took the ride across the park’s dark jungle, we could see the eyes of many creatures look at us. Most of the animal there sleep when there sunlight and wake up at night.
