Do you want to live another 100 years or more? Some experts say that scientific progress will one day help humans to last tens of years longer than what is now seen as the natural limit（限制）of the human life span（寿命）.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate（保守估计）.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said progress in using genes as well as nanotechnology（纳米技术）makes it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who research into aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also disagree on what kind of life the super aged might live. “It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120.” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”

Sigmund Freud was one of the first scientists to make serious research of the mind. The mind is the collection of activities based in the brain that involve how we act, think, feel and reason.
He used long talks with patients and the study of dreams to search for the causes of mental and emotional problems. He also tried hypnosis(催眠术). He wanted to see whether putting patients into a sleep-like condition would help ease troubled minds. In most cases he found the effects only temporary.
Freud worked hard, although what he did might sound easy. His method involved sitting with his patients and listening to them talk. He had them talk about whatever they were thinking. All ideas, thoughts and anything that entered their mind had to be expressed. There could be no holding back because of fear or guilt.
Freud believed that all the painful memories of childhood lay buried in the unconscious self. This part of the mind he said contains wishes, desires and experiences too frightening to recognize.
He thought that if these memories could somehow be brought into the conscious mind, the patient would again feel the pain. But this time, the person would experience them as an adult. The patient would feel them, be able to examine them and, if successful, finally understand them.
Using this way, Freud reasoned, the pain and emotional pressure of the past would be greatly weakened. They would lose their hold over the person's physical health. Soon the patient would get better.
Many of Freud's theories about how the mind works also had strong sexual connections. These included what he saw as the repressed feelings of sons toward their mothers and daughters toward their fathers.
If nothing else, Freud's ideas were revolutionary. Some people rejected them. Many others came to accept them. But no one disputes his great influence on the science of mental health

1.
How many methods did Sigmund Freud use to study the mind?
1. A.
  One
2. B.
  Two
3. C.
  Three
4. D.
  Four
2.
Sigmund Freud’s research was difficult because ______
1. A.
  he had to work hard and have patients talk freely
2. B.
  he had to live with people who had troubled minds
3. C.
  he had to listen to unhappy stories of different people
4. D.
  he had to give his patients a sense of security
3.
Sigmund Freud held the idea that the painful memories of childhood ______
1. A.
  could be forgotten forever
2. B.
  could have a life-long influence
3. C.
  could become wises and desires

  could be understood unconsciously

As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you

1. A.
  the common cold is caused by only one virus

When someone has deeply hurt you, it can be extremely difficult to let go of your grudge. But forgiveness is possible and it can be surprisingly helpful to your physical and mental health. Indeed, research has shown that people who forgive report more energy, better appetite （胃口） and better sleep patterns. "People who forgive show less anger and more hopefulness," says Dr. Frederic Luskin, who wrote the book Forgive for Good. “So it can help save on the wear and tear, and allow people to feel more energetic."
So when someone has hurt you, calm yourself first. Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love. Don’t wait for an apology. "Many times the person who hurt you may never think of apologizing," says Dr. Luskin. "They may have wanted to hurt you or they just don't see things the same way. So if you wait for people to apologize, you could be waiting a very long time.” Keep in mind that forgiveness does not necessarily mean accepting the action of the person who upset you. Mentally going over your hurt gives power to the person who brought you pain. Instead, learn to look for the love, beauty and kindness around you. Finally, try to see things from the other person' s perspective. You may realize that he or she was acting out of ignorance(无知), fear even love. To gain perspective, you may want to write a letter to yourself from that person’s point of view

1.
The word “grudge” in the first paragraph most probably means______.
1. A.
  understanding
2. B.
  forgiveness
3. C.
  anger
4. D.
  pity
2.
What’s the main idea of the first paragraph?
1. A.
  Forgiveness keeps yourself from being hurt
2. B.
  Forgiveness helps stay mentally healthy
3. C.
  Forgiving others does good to your health
4. D.
  Forgiving yourself is the biggest challenge
3.
According to the writer, what is the best way to calm down after being hurt?
1. A.
  Try to figure out why you get hurt
2. B.
  Writer a letter to person who hurt you
3. C.
  Persuade yourself to accept what others have done to you
4. D.
  Think about pleasant things and forget about the hurt
4.
Dr. Luskin advises us not to wait for an apology after being hurt because ______.
1. A.
  people seldom want to apologize
2. B.
  we’d feel worse accepting others' apology
3. C.
  we are not patient enough
4. D.
  people don’t mean it when they apologize

Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives

1.
What’s the main idea of the passage?
1. A.
  An auto revolution is on its way
2. B.
  Google has developed a driverless car
3. C.
  The Carbot has passed its early testing stages
4. D.
  Science fiction has turned into reality
2.
The driverless car is safer than an auto with people because _______
1. A.
  it uses radar, lasers and video cameras
2. B.
  it knows speed limits, traffic patterns and road maps
3. C.
  the computer has a better sense of direction than drivers
4. D.
  the software responds to emergencies faster than a human driver
3.
The advantage of the Carbot is that _______
1. A.
  it can drive all by itself
2. B.
  it can avoid any traffic accident
3. C.
  it doesn’t pollute the environment
4. D.
  it is the most fashionable car nowadays
4.

Puerto Rico may be part of the USA but its music and dance is a mixture of both Spanish and African rhythms. The country, as a result, is a mixture of very new and very old. It exhibits the open American way of yet retains the more formal Spanish influences. This is reflected in the architecture, not just the contrast between the colonial and the modern in urban areas but also in the countryside, where older buildings sit side by side with concrete schools and buildings.
However, if you do not wander beyond the tourist areas on the coast, you will not experience the real Puerto Rico. Old volcanic mountains, long inactive, occupy a large part of the interior（内陆）, with the highest peak, Cerro de Punta, at 1,338m in the Cordillera Central. North of the Cordillera is the karst （岩溶）country where the limestone（石灰石）has been acted upon by water to produce a series of small steep hills and deep holes. The mountains are surrounded by a coastal plain with the Atlantic shore beaches cooled all the year round by trade winds.
The population is 3.8 million, of which about 1.5 million live in San Juan, although about another two million Puerto Ricans live in the USA Average life expectancy is 73.8 years and GDP per capita is US $12,212, the highest in Latin America, although not up to the level of mainland USA. Most Puerto Ricans do not speak English and less than 30% speak it fluently. Second generation Puerto Ricans who were born in New York but who have returned to the island, are called Nuyoricans. The people are very friendly and hospitable but there is crime, liked to drugs and unemployment

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.
First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above. Lastly, there are many people who do not eat meat because they just do not like the idea of killing animals for food. They believe that life, all life, is valuable , and that we do not have to destroy life to feed ourselves when there are other good sources of food

According to the passage, people choose to be vegetarians for the following reasons EXCEPT______.

  Heart disease and cancer are caused by large amounts of protein
3. C.
  There are twice as many meat-eaters as vegetarians who die of cancer

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, “ You should have goals(目标） like climbing the mountain.” Without the mountain- climbing that we both enjoyed, we couldn’t have enough time to spend together because my father was very busy. I really got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.
Once we climbed a very high mountain. It was so challenging(挑战) for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the bird’s singing. But as time passed, I got a pain （痛）in both of my legs. I wanted to give up climbing, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before reaching the top. Only there can you see all of the nice things, which is just like your life.”
At that time, I was too young to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal.

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(伤害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch（伸展）to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.
Many snakes eat birds’ eggs or frogs（青蛙）. Others eat pests（害虫）, mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts
