Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.
The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells which make it beat.Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha.“This is part of the ageing process.”
What amazes scientists is that the female heart suffers very little loss of these cells.A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.
“This gender （性别）difference might give the reason why men live shorter than women,”said Samantha.They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease.“The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.
But there is also good news -- men can enjoy the health of their hearts with regular exercise.Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.

After two days’ travel, the girls began to realize that Canada is quite empty. At school, they had learned that most Canadians live   71   a few hundred kilometres of the USA border, and Canada’s population   72   only slightly over thirty million, but now they were amazed   73   see such an empty country. They went through a wheat-growing province and saw farms   74   covered thousands of acres.   75   dinner, they were back in an urban area, the busy port city of Thunder Bay at the   76   of the Great Lakes. The girls were surprised at the   77   that ocean ships can sail up the Great Lakes. Because of the Great Lakes, they learned, Canada has more fresh water   78   any other country in the world. In fact, it has one-third of the world’s total   79  water, and   80  of it is in the Great Lakes.

Latest data shows an estimated 39.5 million people around the world are living with HIV, the virus that causes AIDS. According to the report, this means every eight seconds somebody in the world is infected with HIV, resulting in 11,000 people becoming newly infected every day.
The director of UNAIDS, Peter Piot, says most of the new infections, nearly two-thirds, are in Sub-Saharan Africa. But, the biggest increases are in Eastern Europe and Central Asia, where infection rates have risen by more than 50 percent since 2004. He says 2.9 million people died from AIDS-related illnesses this year, the highest number ever.
UNAIDS senior epidemiologist(流行病学家), Karen Stanecki, says infections are rising in countries where HIV prevention programs have not adapted to the changing nature of the epidemics(流行病).  Stanecki noted，"In Thailand, one of our past success stories, a large percentage of new HIV infections are occurring in people considered to be low risk. One third of new infections are among married women."
It says data shows increased use of condoms has resulted in drops in HIV prevalence(流行) among young people between 2000 and 2005 in a number of African countries, including Botswana, Kenya and Zimbabwe. Nevertheless, the report notes young people between the ages of 15 and 24 account for 40 percent of new HIV infections. It finds the risk behavior, such as injecting drug use, homosexuals, is a factor of concern in many regions of the world, especially in Asia, Eastern Europe and Latin America.

An old problem is getting new attention in the United States—bullying．Recent cases included the tragic case of a fifteen-year-old girl whose family moved from Ireland．She hanged herself in Massachusetts in January following months of bullying．Her parents criticized her school for failing to protect her．Officials have brought criminal charges against several teenagers．

Judy Kaczynski is president of an anti-bullying group called Bully Police USA．Her daughter Tina was the victim of severe bullying starting in middle school in the state of Minnesota．She said, "Our daughter was a very outgoing child．She was a bubbly personality, very involved in all kinds of things, had lots of friends．And over a period of time her grades fell completely．She started having health issues．She couldn't sleep．She wasn't eating．She had terrible stomach pains．She started clenching her jaw and grinding her teeth at night．Didn't want to go to school．"

Bullying is defined as negative behavior repeated over time against the same person． It can involve physical violence．Or it can be verbal — for example, insults or threats．Spreading lies about someone or excluding a person from a group is known as social or relational bullying．

And now there is cyberbullying, which uses the Internet, e-mail or text messages．It has easy appeal for the bully because it does not involve face-to-face contact and it can be done at any time．

The first serious research studies into bullying were done in Norway in the late 1970s．The latest government study in the United States was released last year．It found that about one-third of students age twelve to eighteen were bullied at school．

Susan Sweater is a psychologist at the University of Nebraska-Lincoln and co-director of the Bullying Research Network．She says schools should treat bullying as a mental health problem to get bullies and victims the help they need．She says bullying is connected to depression, anxiety and anti-social behavior, and bullies are often victims themselves．

From the case of Tina, we can know that            ．

         A．bullying is rare                     B．victims suffered a lot

         C．schools are to blame                   D．personalities are related

Which of the following is NOT bullying?

         A．To beat someone repeatedly．                  B．To call someone names．

         C．To isolate someone from friends．  D．To refuse to help someone in need．

Why is cyberbullying appealing to the bully?

         A．Because it can involve more people．      B．Because it can create worse effects．

         C．Because it is more convenient．               D．Because it can avoid cheating．

According to Susan Sweater,           ．

         A．bullies are anti-social                            B．bullies should give victims help

         C．students are not equally treated      D．bullies themselves also need help

Which of the following can be the best title of the text?

         A．Bullying—Old Irish Girl Committed Suicide

         B．15-Year-Old Irish Girl Committed Suicide

         C．Cyberbullying-Taking Off in Schools  

D．How to Find Bullying among Teens

Would you eat a ready meal from the fridge rather than cook? Have you been doing internet shopping rather than going to the stores? What can’t you be bothered to do?

    A study into how lazy British people are has found more than half of aduhs are so idle（闲散的）they’d catch the lift rather than climb two flights of stairs.

    Just over 2,000 people were quizzed by independent researchers at Nuffield Health, Britain’s largest health charity. The results were shocking.

    About one in six people surveyed said if their remote control was broken, they would continue watching tile same channel rather than get up.

    More than one third of those questioned said they would not run to catch a bus. Worryingly, of the 654 questioned people with children, 64% said they were often too tired to play with them.

This led the report to conclude that it’s no wonder that one in six children in the UK are classifted as obese（肥胖）before they start school.

Dr Sarah Dauncey, medical director of Nuffield Health, said: “People need to get fitter, not just for their own sake, but for the sake of their families, friends and obviously their pets too. If we don’t start to take control of this problem, a whole generation will become too unfit to perform even the simplest tasks.”

    And Scotland’s largest city, Glasgow, was shamed as the laziest city in the UK, with 75% surveyed admitting they do not get enough exercise, followed closely by Birmingham and Southampton, both with 67%.

The results pose serious challenges for the National Health Service, where obesity-related illnesses such as heart disease and cancer have been on a steady increase for the past 40 years and are costing billions of pounds every year.

72. According to the researchers at Nuffield Health, about_______people who were surveyed would not run to catch a bus.

A. 10            B. 150             C. 330              D. 660

73. One in six children in the UK are classified as obese before they start school because ________.

A. they stay too long a time with their pets  

B. they spend too much time watching TV

C. their parents don’t play with them much  

D. they suffer from obesity-related illnesses

74. ________ is the second laziest city in the UK.

    A. Scotland       B. Glasgow         C. Birmingham       D. Nuffield

75. What’s the writer trying to tell us?

    A. Parents have much to do with their children’s obesity-related illnesses.

    B. British people are getting lazier, which can cause serious social problems.

    C. The National Health Service has to face a lot of serious challenges every year.

    D. A study into how lazy British people are has been carried out at Nuffield Health.
