Shortly after the British naturalist, Charles Darwin, published his theory of evolution, a Victorian lady was asked what she thought of the idea that humans and animals were descended from a common ancestor. "Let us hope it is not true," she said. (46)
This story is probably apocryphal, but it illustrates well the attitudes of the time. (47) Many people accept Darwin's view of how we came into being that our bodies evolved through the process of natural selection acting on our genes.
However, Darwin believed evolution was responsible for far more than just our physical characteristics. He saw it as the major influence in shaping our psychology. In- deed, he predicted that "in the distant future, psychology will be based on a new foundation". (48)
To proponents of concepts like free will and personal responsibility, such an idea seems absurd. (49) Their research has revealed increasing evidence that the human mind is made up of innate mechanisms, which control everything from the way we perceive time and space, to how we learn survival techniques and choose mates.
(50) Steven Pinker, Professor of Cognitive Science at the Massachusetts Institute of Technology, likens language ability to computer software, "children learn a new word every 90 minutes of their waking life for years, then they have to figure out how to string them together using a kind of mental computer program. The essence of human language is the ability to convey new ideas by putting words together in different combinations. Since we all have this language 'software' in our minds, we can figure out what others are saying by the meanings of the words and the order in which they are arranged."
A. Today, we are more comfortable with out past.
B. "And, if it is true, let us hope it does not become public knowledge."
C. But a growing number of scientists are questioning the extent to which our behavior. is controlled by our culture.
D. Many people are calling for controls on cloning immedicte1y before the practice is abused.
E. The foundation was, of course, his theory of evolution.
F. Nowhere is this more obvious than our innate ability to learn languages.

听力原文： When people succeed, it is because of hard work, but luck has a lot to do with it, too. Success without some luck is almost impossible. The French emperor Napoleon said of one of his generals, "I know he's good. But is he lucky？" Napoleon knew that all the hard work and talent in the world can't make up for bad luck. However, hard work can invite good luck..
When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you're preparing yourself opportunity. Opportunity very often depends on luck.
How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance？ One of the biggest lucky mistakes in history is Columbus' so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus' chance discovery wasn't pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round.
People who work hard help make their own luck by being ready opportunity knocks. When it comes to success, hard work and luck are always hand in hand.
(30)
A．Hard work is the most important thing for one's success.
B．Hard work may invite good luck.
C．Good luck plays an important role in one's success.
D．Success has nothing to do with luck.

听力原文： The new US Trade Representative said today that the US will reactivate its complaint against European' subsidies for the aircraft maker Airbus. Both the US and the European Union had filed complaints with the World Trade Organization accusing each other of subsidizing aircraft companies. The US said the European governments were providing cheap loans to help Airbus develop new aircraft. The EU said that the US subsidizes the Boeing Company by giving it government contracts and Washington State tax breaks. Both sides had agreed to suspend their cases in January while they tried to find a negotiated settlement. Today Trade Representative Rob Portman said the EU has continued its cheap loans to Airbus forcing the US to go back to the WTO.
What's the main idea of the news？
A．The EU government provides cheap loans to help Airbus develop new aircraft.
B．The US government subsidizes the Boeing Company by giving it government contracts.
C．The Eli and the US try to find a negotiated settlement on trade war.
D．US make a new complaint against EU subsidies for the aircraft maker Airbus.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory. As philosopher of science, Karl Popper has emphasized a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation. Each time new experiments are observed to agree with the predictions the theory survives, and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory. At least that is what is supposed to happen, but you can always question the competence of the person who carried out the observation.
In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein's general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while Newton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (Newton's theory also. has the great advantage that it is much simpler to work with than Einstein's ! )
It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break the problem up into bits and invent a number of partial theories. Each of these partial theories describes and predicts a certain limited class of observations, neglecting the effects of other quantities, or representing them by simple sets of numbers. It may be that this approach is completely wrong. If everything in the universe depends on everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation. Nevertheless, it is certainly the way that we have made progress in the past. The classic example again is the Newtonian theory of gravity, which tells us that the gravitational force between two bodies depends only on one number associated with each body, its mass, but is otherwise independent of what the bodies are made of. Thus one does not need to have a theory of the structure and constitution of the sun and the planets in order to calculate their orbits:
Today scientists describe the universe in terms of two basic partial theories-the general theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. Unfortunately, however, these two theories are known to be inconsistent with each other-they cannot both be correct. One of the major endeavours in physics today, is the search for a new theory that will incorporate them both-a quantum theory of gravity. We do not yet have such a theory, and we may still be long way from having one, but we do already know many of the properties that it must have.
According to the passage, why can't any physical theory be permanently established？
A．Such a theory is only suggested as a possible way of explaining an idea.
B．The person proposing such a theory may be incompetent.
C．Observations always disagree with predictions.
D．Observations are always falsified by predictions.

A few years ago it was common to speak of a generation gap between young people and their elders.Parents said that children did not respect and listen to them, while children said that their parents did not understand them at all.What had gone wrong？ Why had the generation gap suddenly appeared？ Actually, the generation gap has been around for a long time.Many people argue that it is built into every part of our society.
One important cause of the generation gap is the opportunity that young people have to choose their own ways of life.In a more traditional society, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and like, and often to continue the family jobs.In our society, young people often travel great distances for their education, move out of the family at an early age, marry or live with people whom their parents have never met, and choose jobs different from those of their parents.
In our society, parents often expect their children to do better than they did, to find better jobs, to make more money and to do all the things that they were unable to do.Often, that is another cause of the gap between them.Often, they discover that they have very little in common with each other.
Finally, the speed at which changes take place in our society is the third cause of the gap between the generations.In a traditional culture, senior people are valued for their knowledge, but in our society the knowledge of a lifetime may become out of date.The young and the old seem to live in two very different worlds, separated by different skills and abilities.No doubt, the generation gap will continue in American life for some time to come.
1.The first paragraph tells us that ______.
A、the problem of the generation gap draws much attention from people
B、it is out of date to talk about the generation gap
C、children and parents are trying to understand each other
D、it is very important for people to frequently communicate with each other
2.In a more traditional society, old people_______.
A、have their children respect and listen to them
B、do not care for their children at all
C、expect their children to rebel against them
D、do not live together with their children

A、do not need to find jobs
B、leave home at an early age
C、have better education than their parents
D、marry people younger than them

A、Young people like to depend more on themselves.
B、Parents do not love their children dearly.
C、American society changes rapidly.
D、Parents expect too much of their children.
5.The main idea of the passage is ________.
