There are plenty of creams etc on the market that help you look younger, but today, Dr Oz is going to show how some people are actually living longer.
“We are going to talk about extreme life extension,” he says. “I am talking in details about allowing us to go into our second century of life with the energy that you have when you are a young person.”
Owing to advances in technology and research on how diet affect the aging process, Dr Oz says it might be possible for some people to live to see their 120th birthdays.
There’s one man in Oprah’s audience who Dr Oz says may become the first man in history to live to be 150 years old. Joe Cordell is one of thousands around the world who believe they’ve found the key to an extreme long life --- calorie restriction leads to a longer, healthier life.
At 59 Joe weighs 130 pounds. He may not look like a person who needs to count calories, but as part of his life extension program, he inspects every mouth of food that passes through his system.
Every day for the past seven years, Joe has limited himself to about 1,950 calories.
He believes that by eating less and restricting his caloric intake, he will trigger a genetic switch that slows the aging process.
Joe doesn’t take away himself of food. Instead, the then 52-year-old father filled up on natural fruits, vegetables and lean proteins(瘦蛋白) that were packed with necessary vitamins and nutrients. “Whenever you are thinking about calorie restriction, you should continually think about getting the most nutritional amount per calorie,” Joe says.
In keeping with this principle, Joe starts every morning with three apples…but he only eats the peels. “Most of the fiber is in the peel, and more importantly, most of the nutrients are in the peel,” he says.
“It is important to eat some nuts with breakfast so that you do take in some fat, some healthy fats,” he says. “I think it helps the absorption of the nutrients, and it is very filling.”
For lunch, Joe usually eats a large salad, loaded with vegetables. At dinnertime, he and his family enjoy lean meat or fish and more vegetables.
When Joe started practicing calorie restriction, he weighed 175 pounds. Since then, he has lost 45 pounds, and he says he hasn’t had a cold in seven years. Though he is in his “golden years”, researchers studying Joe say he has the body of a 20-year-old athlete.
小题1: According to Joe, the appropriate fat intake may help ______?

Ifhas anyone noticed how, with the passage of time, one’s relationship with one’s grown-up daughters and sons becomes changed? I’ve been aware of this for some time but I’m not quite sure how to deal with it.
Take the kitchen sink for example.
Following a family get-together at my place, I walked into the kitchen to find Kate, my daughter, carefully cleaning the sink.
“Don’t do that; what are you doing that for?” I said, unhappy about the hidden criticism.
“Mum,” she said, “you really ought to put your glasses on when you clean the sink. Behind the tap here was black!”
But it’s not just things like kitchen sinks. Another time Kate arrived to pick me up to lunch. She looked at me and then asked, “Mum, why do you use brown eyebrow pencil when your hair is grey?”
A sudden memory of her, aged 14, going to her first mixed party flooded back. She had come in to say goodbye. For a moment I thought she’d been an accident. Both eyes were black. I remember suggesting that perhaps a little less eye make-up might be more effective.
Now I told her, “My hair used to be brown.”
“It looks absurd.(荒唐)”
“Mrs. Menzies had dark eyebrows with grey hair.”
“Yes, but you’re not Mrs. Menzies, are you?” she said triumphantly, as if that proved her point.
But a recent event made me realize that something really must be done.
She had returned home for a few weeks before getting married. One evening I went out on a dinner date. By the time my companion left me at the front door, it was about 2am. As I stepped in, an angry figure in a white nightgown（睡衣）stopped me.
“Well, what time of night is this to be coming home?” she shouted. “Where have you been? I’ve been worried sick!”
Shades of the past come back to disturb me. But what should I do about all this? Nothing, probably. Maybe, after all, it’s only a stage young people are going through.

Everyone has got two personalities (性格) —the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by new ideas. You don’t like to make people unhappy, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you’re always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel worried, but you don’t often get unhappy. You always say what you think, even if it makes people angry.

Before discussing different kinds of emotions, let us briefly talk about how researchers   1 bodily processes, actions and behavior, and how this relates to what we do in our daily lives when we observe emotions in 2  .
Bodily processes can be directly measured by   3  of a polygraph. (测谎器)When a polygraph is skillfully used to   4 how we react bodily with what we are   5 , it is called a "lie detector". Bodily processes can also be measured 6 . This is what we do when we observe someone blushing (脸红). However, we are not always 7  of what bodily processes respond to.
Measuring action   8  behavior is the other way researchers assess the emotions.    9 , one measure of fear of snakes is how 10 a person will go to the snake. Another procedure is to have a person 11 how afraid he is, or how he feels, in this way, researchers have 12 the so-called "fear thermometer" to assess a person’s fear. 13  our everyday living, we do very much the same thing. Only not too   14 . We react to what a person does, what he says, 15  he says it, and how he looks. Is he smiling? Is his voice trembling? We put all this 16 together to infer what a person is feeling.
17 , we do not always act as we feel. Sometimes we do things that we don’t feel like doing. 18 we say we feel one way and then we act another. Actors, for example, successfully learn to "make believe" emotions, or learn to   19  them. Thus we   20  always tell what a person is feeling by what he says or by what he does.

Wind , water, fire and ice-these powerful natural forces have shaped the land of America in the past. They are still changing it today.
The Colorado River slowly cut down through stone to make the Grand Canyon(大峡谷).
Long ago, ice sheets cut Yosemite Valley and the Great Lakes, and glaciers(冰川) are still on the move in Alaska.
Wind and rain storm hit the land from time to time. Fires sometimes burn down forests and destroy the homes of wild animals. This happened in Yellowstone Park in 1988.
Dead volcanic mountains such as Haleakala on Maui and Carter Lakein Oregon are beautiful to look at. But there are several active volcanoes in the US, especially along the Pacific Coast. There are also many earthquakes in this area. Scientists can do nothing to control earthquakes or volcanoes. This was shown clearly on May 18, 1980. At 8:32 that morning, Mount St Helens in Washington state broke out. The top of the mountain was blown off.
Over 60 people –campers, scientists, journalists, forest workers—were killed. Hundreds of square miles of forests were knocked down. In towns over 100 miles away, day suddenly became night. An ash cloud hid the sun for many hours. Towns and fields in Washington, Oregon, and Idaho were covered with dirty gray ash.
Scientists knew that Mt St Helens might erupt(爆发) soon. But no one could say when. And no one expected the terrible strength of the eruption. Many people were surprised and unready. Harry R. Truman, 84, owned a small hotel in Mt St Helens. Scientists had asked people to move away because the volcano was becoming dangerous.
But Harry Truman would not leave his home. Now it is covered with many feet of dirty ash. A small cross stands above the place where Harry probably died. Perhaps it is better that he did not see the destruction of Mt St Helens, the once beautiful lake, and the forests.
But slowly, life is returning to the dead area around the mountain. Grass and small plants are beginning to grow again. Deer and birds have been seen. The land will never be the same as it once was. Perhaps Mt St Helens will erupt again. But this is all part of nature’s pattern of change, and man has little power to control it.

In bringing up children, every parent watches eagerly the child’s acquisition(学会) of each new skill---the first spoken words, the first independent steps, or the beginning of reading and writing. It is usual that parents hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, and a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.
Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters, other are severe over time of coming home at night or punctuality (准时) for meals. In general, the controls imposed (强加的) represent the needs of the parents and the values of the community as much as the child’s own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parent teaching. To forbid a thing one day and excuse it the next is not foundation for morality. Also, parents should realize that “example is better than precept”. If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents’ principles and their morals can be a dangerous disappointment.
小题1: Eagerly watching the child’s acquisition of new skills ________.

A．should be avoided

B．is universal among parents

C．sets up dangerous states of worry in the child

D．will make him lose interest in learning new things

小题2:When children are learning new skills, parents should _________.

A．encourage them to read before they know the meaning of the words they read

B．not expect too much of them

C．achieve a balance between pushing them too hard and leaving them on their own

D．create as many learning opportunities as possible

小题3:The second paragraph mainly tells us_________.

A．parents should be strict with their children

B．parents controls satisfy only the needs of the parents and the values of the community

C．parental restrictions vary, and are not always enforced for the benefit of the children alone

D．parents vary in their strictness towards their children according to the situation

小题4:In moral matters, parents should _________.

A．observe the rules themselves

B．be aware of the marked difference between adults and children

C．forbid things which have no foundation in morality

D．satisfy their children’s needs

It’s interesting that the arrival of snow has a different effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others it is a catastrophe (灾难).
There are countries between these two extremes that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one such country, for which the arrival of snow quite simply creates problems. Within hours of the first snowfall, however light, roads are blocked, trains and buses stop in the middle of traffic. Normal communications are affected as well, telephone calls become difficult and the post immediately takes more time than usual. Almost within hours, there are also shortages(缺乏) –bread, vegetables and other things – not because all these things can no longer be produced or sent to shops, but mainly because people are frightened, and go out to store up these commodities, “just for fear that something bad should happen.”
Why then does snow have this effect? After all, the Swiss, Austrians and Canadians don’t have such problems. It is simply because there is not enough plan and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow ploughs and machines to spread salt. The reason why a country like Britain does not buy some ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospital education or helping the old.
小题1:According to the writer, Britain is a country____.

A．which has regular snow	B．which is not well prepared for snow
C．for which snow is not a catastrophe	D．for which snow is a wonder

小题2:The arrival of snow in Britain affects all of the following except____

小题3:After a few hours’ snowing there are often shortages of food because______

A．shops have closed down	B．people buy as much as they can
C．farmers can’t produce any more	D．people eat more vegetables in winter

小题4:The first reason why the British don’t buy snow ploughs is that______

A．spreading salt is good enough	B．old people need more money
C．snow ploughs are not used often	D．the hospital is more important

A．Don’t Play Games Any More	B．New Study of IQ
C．Brain Games Don’t Raise IQ	D．Brain Games and Super Mario
