Do you know that men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
　　The largest study of the effects of ageing(變老) on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
　　“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
　　“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”
　　What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
　　“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
　　The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

A Avoid asking your child too many questions
B Tell your child stories about your growing up
C Don’t judge or criticize your child
D Listen to your kids with respect
E Provide pressure-free conversation opportunities
F Ask children gently what they think
   If your child has gone from a continuous chatterbox to making conversations that consist mostly of yes and no, it’s time to consider these tips on how to talk to kids, so you’ll know what’s going on in your child’s world.
小題1:  
The quickest way to get kids to shut up and, as a result, shut you out of their lives is to continuously press them about things. A more effective way is to sit back and patiently wait for them to open up in a low-stress family and then be prepared to listen.
小題2:  
Parents can sometimes make kids at a young age decide it is best not to talk about something when they are criticized. If you really want to know what’s on your child’s mind, then avoid passing judgment and focus instead on why something seems important to your child.
小題3:
If you want to raise a creative and independent thinker, stop telling your child what he ought to feel or think. You can gently encourage additional conversations by simply asking why he feels the way he does or what he would do in a certain situation.
小題4:  
You may think you’re just asking questions out of curiosity when communicating with your child, but an endless stream of questions about what they did, whether everyone got along, if they went to the bathroom, ect., are enough to make anyone shut up! Practice patience and let your kids open up on their terms.
小題5:
Kids can relate to you and other adults when you tell your stories happening when you were their age. Talking to kids by telling them about things like something embarrassing that happened or the first crush(迷戀) you had helps them to connect with you and understand that you might actually know what they are going through!

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.
Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.
“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.
The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.
“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近親交配) problems ... and at the end these species may disappear,” he added.
Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.
The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.
Other consequences could include the spread of invasive species and infectious diseases, it said.
The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(紅樹林), inland waters, forests, savannahs(非洲大草原) and grasslands.
The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.
The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.
It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.
小題1:What does the author tell us in Paragraph 2?
A．The theme of global climate negotiations in Durban.
B．The subject of research done by Eduardo Rojas.
C．Causes of damage done to ecosystems.
D．Harmful effects of damage done to ecosystems.
小題2:Why are animals living in mountains, islands and coastal areas most affected?
A．They are frequently attacked by invasive species and infectious diseases.
B．They have difficulty finding enough food for survival.
C．They can hardly find mates to produce their young.
D．They have little chance of moving to other places.
小題3:To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT ______.
A．restoring damaged ecosystems
B．limiting world population growth
C．creating movement channels for animals
D．urging governments and local communities to take action
小題4:What does the underlined word “mitigate” in the last paragraph mean?
A．increase or further improve something.
B．Make full use of something.
C．Make something become less serious.
D．Move from one place to another.
小題5:What would serve as the best title for the passage?
A．Animals at risk due to climate change.
B．Global warming and its consequences.
C．Climate change and ecotourism.
D．Solutions to animal distinction.

Earlier this year, the Environmental Protection Agency proposed a stricter nationwide health standard for smog-causing pollutants that would bring substantial benefits to millions of Americans. With a final rule expected by the end of this month, some opponents, mainly from industrial and oil-producing states, are pushing back. They say investments required to produce cleaner air are too expensive and not scientifically justified.
Lisa Jackson, the E.P.A. administrator, needs to stick to her guns. This is only the first of several political tests to come this fall, as she also seeks to tighten rules governing individual pollutants like mercury and global warming gases like carbon dioxide.
The health standard she is proposing covers ground-level ozone, commonly known as smog, which is formed when sunlight mixes with pollutants from factories, refineries, power plants and automobiles. Ozone is a major health threat, contributing to heart disease and various respiratory (呼吸道的) problems.
Ms. Jackson’s proposal—to reduce the permitted level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billion—is sensible, no matter what industry’s defenders may claim. It had been recommended by the agency’s independent scientific panel but rejected by the Bush administration, which proposed a weaker standard.
Industry will have to make investments in cleaner power plants, and new technologies may be required. As it is, about half the counties that monitor ozone levels are not yet in compliance with current standards, let alone the proposed standard.
Fears about burdening industry raised by critics like George Voinovich, a Republican of Ohio, and Mary Landrieu, a Democrat of Louisiana, cannot be dismissed out of hand, especially in the middle of a recession (蕭條). But the health benefits, E.P.A. says, far outweigh the costs, and the time frame for compliance (服從) is generous.
小題1:Why are some people strongly against a stricter limitation of smog-caused pollutants?
A．Because they have to live a poorer life.
B．Because they think they have to spend more money.
C．Because they hold different political view.
D．Because they want to make more money.
小題2: What does Ms Jackson propose to do?
A．To reduce the permitted smog level as much as possible.
B．To raise the permitted smog level as much as possible.
C．To keep the permitted smog level from 60 to 70 to 75 parts per billion.
D．To lower the permitted smog level from 75 to 60 to 70 parts per billion.
小題3:What is the attitude of the author to the smog-controlling issue?
A．Objective.B．Subjective.C．Critical.D．Unknown.
小題4:Which of the following can serve as the best title of the whole passage?
A．Cleaner power plant on the way.
B．Say no to smog pollutants.
C．Lower smog pollutant, better our life.
D．Debate on smog pollutants.

EAT YOUR VEGETABLES.Wash your hands. Always say  “please” and “thank you”. We are full of advice for our children, but when it comes to money, we often have little to say. As a result, our children may grow up with clean hands and good manners, but without any idea how tomanage their money.
　　Here are some basics that will help guide them their entire lives:
　　Show them the future. If your 13-year-old girl were to save $1.000,invest(投資)it at 8% and add $100 every month, by the time she’s 65,she would have $980,983!
　　Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history, but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card, you can easily end up paying two or three times what you would have paid if you used cash.
　　Teach patience. Suppose your child wants a new bicycle that costs $150.Rather than paying the cash, give him some regular pocket money and explain that by putting aside,say,$15 each week, he will be able to buy it for himself in only ten weeks.
　　Provide incentive. Tell your children the importance of saving. “For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot,” says Cathy Pareto, expert in money planning.
　　Explain your values. Values and money are deeply intertwined, says Eilleen Gallo,co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don’t want to buy it.“You might say, ‘I’d rather save that money for your  education,’” advises Gallo. Every time you spend or don’t spend money, you have a chance to share your values.
小題1:The writer gives some basics to help________ in a proper way.
A．parents teach their children how to deal with money
B．children follow their parents’ instructions
C．children manage their money
D．parents save their money
小題2:The writer thinks that, if a child wants to buy something, his parents should________.      .
A．give him some regular pocket money
B．encourage him to put money away for it
C．explain to him the importance of investment
D．tell him to save some money by using a credit card
小題3:The underlined word “incentive” in paragraph 6 means_________.       .
A．honorB．praiseC．excitementD．encouragement
小題4:What leads the writer to write this article?_________
A．Parents want to know how to educate their children.
B．He wants to share his good ideas about money matters.
C．He thinks money management the most important for children.
D．Parents care Little about their children’s management of money.

To master a language one must be able to speak and understand the spoken language as well as to read and write．Lenin and his wife translated a long English book into Russian but when they went to England in 1902, English people couldn't understand a word Lenin and his wife said, and Lenin and his wife couldn't understand what was said to them．This shows the importance of spoken language．
Speaking, of course can't go without listening．If you want to pronounce a word correctly, first you must hear it correctly．The sounds of Chinese and English languages are not exactly the same．If you don't listen carefully, you'll find it difficult or even impossible to understand the native speakers．
Well, what about writing﹖ Like speaking, it's to exchange ideas．People usually use shorter words and shorter sentences in their writing．
The important thing is to make your idea clear in your mind and then to write it in a clear lively language．
Chinese students read too slowly．If you read fast, you understand better．If you read too slowly by the time you have reached to the end of a page you have forgotten what the beginning is about．When you meet with new words don't look them up in the dictionary．Guess the meaning to form the context. You may not guess quite correctly the first time but as new words appear again and again in different context their meaning will become clearer and clearer. If you look up every word you'll never finish a book．
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they're studying. They should study those subjects in the foreign language not only in translation．In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time．
小題1:In England Lenin        ．
A．could be understood by Englishmen
B．could understand Englishmen
C．a(chǎn)nd Englishmen couldn't understand each other
D．a(chǎn)nd Englishmen could understand each other
小題2:In the first paragraph the writer told us        ．
A．how to speak English
B．how to read and write
C．why English people couldn't understand the Lenins
D．spoken English is important
小題3:In the fifth paragraph the writer advised us on        ．
A．how to guess the meaning of the words
B．how to read fast
C．how to look up new words in the dictionary
D．how to read carefully
小題4:“Kill two birds with one stone” means        ．
A．to get some particular knowledge
B．to get more than what one pays
C．the stone is very useful
D．the birds are blind enough
小題5:In the last paragraph the writer advised us        ．
A．to kill two birds with one stone
B．to learn two languages at the same time
C．to study all the subjects in a foreign language
D．to get some knowledge of the foreign country whose language we are studying
