根据材料,完成下面的题目。Kicking the Habit What is a bad habit? The most definition is that it is something that we do regularly, almost without thinking about it. and which has some sort of negative consequence. This consequence could affect those around us, or it could affect us personally. Those who deny having bad habits are probably lying. Bad habits are part of what makes us human. Many early habits, like sucking out thumb, are broken when we are very young. We are either told to stop doing it by our parents, or we consciously or subconsciously observe that others do not have the same habit, and we gradually grow out of it. It is when we intentionally or unintentionally pick up new habits in our later childhood or early adulthood that it becomes a problem. Unless we can break that habit early on, it becomes a part of our life, and becomes "programmed" into our brain. A recent study of human memory suggests that no matter how hard we try to change out habits, it is the old ways that tend to win, especially in situations where we are rushed, stressed or overworked. Habits that we thought we had got rid of can suddenly come back. During the study program, the researchers showed a group of volunteers several pictures, and gave them words to associate with them. They then showed the volunteers the same picture again, and gave them new words to associate with them. A few days later, the volunteers were given a test. The researchers showed them the pictures, and told them to respond with one of the words they had been given for each one. It came as no surprise that their answers were split between the first set of words and second. Two weeks later, they were given the same test again. This time, most of them only gave the first set of words. They appeared to have completely forgotten the second set.The study confirms that the responses we learn first are those that remain strongest over time. We may try to change out ways, but after a while, the response that comes to mind first is usually the first one we learned. The more that response is used, the more automatic it becomes and the harder it becomes to respond in any other way. The study therefore suggests that over time, our bad habits also become automatic, learned behavior. This is not good news for people who pick up bad habits early in life and now want tochange or break them. Even when we try to put new, good intentions into practice, those previous learned habits remain stronger in more automatic, unconscious forms of memory.Boys usually develop bad habits when they are very young.
根据以下材料回答下面的题目:Benefited or HurtFor the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich country counterparts to benefit, because they have less to lose and more to gain. Orthodox economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labor have already been used up. If pool countries lower their barriers to trade and investment, the theory goes: rich foreigners wilt want to send over some of their capital.If this inflow of resources arrives in the form of loans or portfolio investment, it will supplement domestic savings and loosen the financial constraint on additional investment by local companies. If it arrives in the form of new foreign controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investmentought to push incomes up, partly by raising the demand for labor and partly by making labor more productive. This why workers in FDI receiving countries should be in an even better position to profit from integration than workers in FDI sending countries. Also, with or without inflows of foreign capital, the same static and dynamic gains from trade should apply in developing countries as in rich ones. This gain from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets though trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all these transactions, sides exporters and importers, borrowers and lenders, shareholders and workers can gain.According to the passage, who may be reasonably afraid of the globalization?

根据下列材料,回答下面的题目DNA Fingerprinting DNA is the genetic material found within the cell nucleus of all living things.In mammals the strands of DNA are grouped into structures called chromosomes.With the exception of identical siblings(as in identical twins),the complete DNA of each individual is unique. DNA fingerprinting is sometimes called DNA typing.It is a method of identification that compares bits of DNA.A DAN fingerprint is constructed by first drawing out a DNA sample from body tissue or fluid such as hair,blood,or saliva.The sample is then segmented using enzymes,and the segments are arranged by size.The segments are marked with probes and exposed on X—ray film,where they form a pattern of black bars—the DNA fingerprint.If the DNA fingerprints produced from two different samples match,the two samples probably came from the same person. DNA fingerprinting was first developed as all identification technique in 1985.Originally used to detect the presence of genetic diseases,it soon came to be used in criminal investigations and legal affairs.The first criminal conviction based on DNA evidence in the United States occurred in l988.In criminal investigations,DNA fingerprints derived from evidence collected at the crime scene are compared to the DNA fingerprints of suspects.Generally,coups have accepted the reliability of DNA testing and admitted DNA test results into evidence.However,DNA fingerprinting is controversial in a number of areas:the accuracy of the results,the cost oftestin9,and the possible misuse of the technique. The accuracy of DNA fingerprinting has been challenged for several reasons.First,because DNA segments rather than complete DNA strands are “fingerprinted”;a DNA fingerprint may not be unique;large—scale research to confirm the uniqueness of DNA fingerprinting test results has not been conducted.In addition,DNA fingerprinting is often done in private laboratories that may not follow uniform testing standards and quality controls.Also,since human beings must interpret the test,human error could lead to false results. DNA fingerprinting is expensive.Suspects who are unable to provide their own DNA to experts may not be able to successfully defend themselves against charges based on DNA evidence. Widespread use of DNA testing for identification purposes may lead to the establishment of a DNA fingerprint database. If two sisters are identical twins.their complete DNAs are _________.
