CHICAGO -- New research on vegetables and aging gives mothers another reason to say "I told you so." It is found that eating vegetables appears to help keep the brain young and may slow the mental decline（下降） sometimes associated with growing old.

On measures of mental sharpness, older people who ate more than two servings of vegetables daily appeared about five years younger at the end of the six-year study than those who ate few or no vegetables.

The research in almost 2,000 Chicago-area men and women doesn't prove that vegetables reduce mental decline, but it adds to mounting evidence pointing in that direction. The findings also echo（回应） previous research in women only.

Green leafy vegetables including spinach（菠菜）, kale and collards （甘蓝） appeared to be the most beneficial. The researchers said that may be because they contain healthy amounts of vitamin E, an antioxidant（抗氧化剂） that is believed to help fight chemicals produced by the body that can damage cells.

Vegetables generally contain more vitamin E than fruits, which were not linked with slowed mental decline in the study. Vegetables also are often eaten with healthy fats such as salad oils, which help the body absorb vitamin E and other antioxidants, said lead author Martha Clare Morris, a researcher at the Rush Institute for Healthy Aging at Chicago's Rush University Medical Center.

The fats from healthy oils can help keep cholesterol（胆固醇）low and arteries （动脉）clear, which both contribute to brain health. The study was published in this week's issue of the journal Neurology and funded with grants from the National Institute on Aging.

1.In which part of newspaper can you find this article?

A. entertainment　　 B. sports　　 C. health　　 D. education

2.According to the passage, which of the following statements is TRUE?

A. The research has showed that eating vegetables may be beneficial to our brain.

B. The new research is tested among 2,000 females.

C. The findings of the new research do not agree with the previous one.

D. It has been clearly proved that eating vegetables can help keep the brain young.

3.We can conclude from the text that our brain can be healthy if our body contains the following except_____.

A. green leafy vegetables　　 B. fats and oil

C. clear arteries　　 D. healthy amounts of vitamin E

"This is a sound paper and contributes to our understanding of cognitive（认知的）decline, "said Dr Meir Stampfer of Harvard's School of Public Health.

"The findings specific for vegetables and not fruit add further credibility（可信性）that this is not simply a marker of a more healthful lifestyle, "said Stampfer, who was not involved in the research.

The research involved 1,946 people aged 65 and older who filled out questionnaires about their eating habits. A vegetable serving equaled about a half-cup chopped or one cup if the vegetable was a raw leafy green like spinach.

Scientific research gives new explanations to a very old relationship.

Dog Sense: How the New Science of Dog Behaviour Can Make You a Better Friend to Your Pet. By John Bradshaw. Basic Books; 324 pages; $25.99. Buy from Amazon.com, Amazon.co.uk

Dogs seem to have been our beloved companions since there was written history. It is hard to be precise(精确地) about when the friendship began, but a reasonable guess is that it has been going strong for more than 20,000 years. For John Bradshaw, a biologist who founded the anthrozoology department(the place known as human-non-human-animal studies) at the University of Bristol, having some idea about how dogs got to be dogs is the first step towards gaining a better understanding of human-dog relationship. It is generally accepted that dogs were raised by human beings from wolves. However, Bradshaw’s research refuted the wrong ideas about the close relationship of dogs to wolves and the mistakes that this has led to, especially in the training of dogs over the past century or so.

Dogs are not like nicely brought-up wolves, says the author, nor are they much like people despite their excellent ability to enter our lives and our hearts. However, dogs have a distinguish talent: they experience and react to the world through their extraordinary sense of smell: their sensitivity to smells is between 10,000 and 100,000 times greater than ours. And their trainability allow dogs to perform almost unimaginable tasks, such as smelling the early stages of a cancer long before a normal medical diagnosis(诊断) would discover it.

The latest scientific research can help dogs and their owners have happier, healthier relationships by encouraging people to understand dogs better. But Mr. Bradshaw is also fearful. In particular, he fears the incestuous（近亲繁殖）narrowing of the gene pool that modern breeders have brought about. He also worries that the increasing urbanization of society and the pressures on couples to work long hours are putting dogs under huge stress.

“Dog Sense” is neither a report nor a description of the joys of dog-ownership. At times its use of research data can be slightly difficult to understand. But this is a wonderfully informative, instructive book that will do good to every dog whose owner reads it.

1.What’s the meaning of the underlined word in Paragraph 3?

A.Proved B.Disagreed C.Described D.Explained

2.Which of the following statements about dogs is not true according to the passage?

A.Dogs and wolves are close relatives.

B.Some dogs can smell early stage cancers.

C.The relationship between dogs and humans has a long history.

D.Dog may suffer from depression.

3.The purpose of the passage may be 　　　　　 .

A.to introduce something about dogs

B.to present the result of a book

C.to change people’s attitude towards dogs

D.to advertise a book about dogs

4.How does the author find Dog Sense?

A.Boring B.Interesting C.Useful D.Hard

New research has found that even if you give up smoking,the damage it has done to your genes（基因）will stay there for a much longer time.

In the research,a team of US scientists studied the blood of 16,000 people.Among them, some were smokers,some used to smoke,and the rest were non-smokers.Scientists compared their genes and found that more than 7,000 genes of smokers had changed a number that is one-third of known human genes.

When you stop smoking,a lot of these genes will return to normal within five years.This means your body is trying to heal（治愈）itself of the harmful effects of smoking.But the changes in some of the genes stay for longer.They can stay for as long as 30 years.It’s almost like leaving a footprint on wet cement（水泥）— it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy,there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer ricks.

New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time.

In the research, a team of US scientists studied the blood of 16, 000 people. Among them, some were smokers, some used to smoke, and the rest were non­smokers. Scientists compared their genes and found that more than 7, 000 genes of smokers had changed—a number that is one­third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day­to­day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years. This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years. It’s almost like leaving a footprint on wet cement (水泥) — it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side:the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

1.The function of Paragraph 1 is to ______.

A. give an example

Leonardo da Vinci’s mother may have been a Chinese slave according to a new research by an Italian historian and novelist—Angelo Paratico, who has spent the last 20 years living and working in Hong Kong, researching the links between his homeland and China over the past half century.

Mr Paratico said the documents he has uncovered during two years of research form the basis of his latest book Leonardo Da Vinci, a Chinese scholar lost in Renaissance(文艺复兴)Italy. The book, which is due to be published next year, uncovers evidence that there’s a link between Da Vinci and the Far East.

Speaking to the South China Morning Post, Mr Paratico said, “I am sure that Leonardo’s mother was from the East, but to make her a Chinese, we need to use a deductive method(演绎法). One wealthy client of Leonardo’s father had a slave called Caterina. After Leonardo’s date of birth, she disappeared from the documents．She was no longer working there.’’

It is believed that his mother was called Caterina, who, according to some reports, was a local peasant. But Mr Paratico’s new work claims it is most likely that Da Vinci’s mother was a slave. Supporting his theory, he said, “During the Renaissance, countries like Italy and Spain were full of slaves from the East.”

He claimed that there were certain aspects of Da Vinci’s life and works which suggest a Chinese link. For instance, he was writing with his left hand from left to right and he was also a vegetarian, which was not common. Mona Lisa is probably a portrait of his mother，as Sigmund Freud said in 1910. On the back of Mona Lisa, there is a Chinese landscape and even her face looks Chinese.

Mr Paratico said he believes the only way to solve the mystery is to dig out some of Da Vinci’s relations in Florence and extract some DNA.

1.What is Mr Paratico’s latest book based on?

A. His research findings．　　 B. His living experience．

C. His final visit to Italy．　　 D. His interest in Renaissance．

2.What may suggest there is a link between Da Vinci and Chinese?

A. His working habit．　　 B. His ways of writing．

C. His birth date．　　 D. His father’s friend．

3.What can we learn about Da Vinci’s mother?

A. She was a slave of Leonardo’s father．

B. She quit working after her marriage．

C. She was buried in Florence after death．

D. She was probably the model of Mona Lisa．
