There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother's body which divides to form. two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form. babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.There is a third type of twins, but it is a very unusual one.

One of the greatest contributions ofFreud is that he elaborated the structure of human psyche as "Id","Ego" and "Superego". "Ego" is the natural humanpsychological characteristic that changes everything in its way and makeseveryone a victim to undesirable consequences in their life. The pride andself-esteem if they are overrated in our mind will be shown in the form of Ego.The Human Ego conceals our "natural intellect" to create falseownership over every object. Here is an interesting story which couldillustrate the case.Once there was a scientist who worked hardall through his life to make exact human physical body replicas of himself. Hemastered the art so perfectly that one could not easily tell the replica fromthe original. According to the natural process, the Angel Death knocked at hisdoor. The Angel Death felt puzzled by looking at the thirteen same persons.Obviously unable to recognize the original person, the Angel returned in vain.The scientist got the illusion that he can avoid death easily.Nevertheless the Angel Death who has clearunderstanding of human life did not give up and came back with a trick Sheagain approached the scientist and was staring at the thirteen human figures.Then she told the scientist, "You havemanaged everything correctly but you could not avoid a small flaw whilereproducing yourself′. The scientist hurriedly spoke out the small flaw that itwas impossible in his work. Then he was caught by Angel Death.The Ego blinds us to hide reality, so wetend to make small mistakes though we are given greater skills and strength.Therefore each one of us has to be careful about our accomplishments andachievements so that we don′t make us blind toward this living world whereevery individual is presented upon with equal grace and strength. Thus we haveto decrease the feeling of "All is I" and increase the feeling of"I am nothing before All", which makes us proud of everything wehave.How did the Angel Death find out theoriginal of the scientist?A.By her own naked eyes.B.By finding the flaw of the scientist.C.By cheating the scientist.D.By making small mistakes.

单选题A brand of cough syrup comes with a measuring cup attached so that customers can measure the proper dosage. A consultant has pointed out that this cup is unnecessary, since most customers have measuring cups at home. Since the cups increase the cost of packaging the cough syrup and reduce the total number of units that can be shipped in a standard package, the consultant advises that the company can increase its net revenue on this product (total revenue minus total costs) by selling the cough syrup without the measuring cups. Which of the following, if true, provides the strongest evidence that the company should not follow the consultant’s advice?AStudies have shown that customers who use cough syrup without a measuring cup frequently take either too little or too much of the medicine, rendering the dosage either ineffective or, in cases of overdose, dangerous.BThe company has included a measuring cup with each bottle of cough syrup for the last 18 years.CStudies have shown that 85 percent of consumers possess at home either a measuring cup, a set of measuring spoons or both.DMany customers neglect to follow the recommended dosage of cough syrup even when the measuring cup is packaged along with the bottle of cough syrup.EShipping the cough syrup bottles without the measuring cups will provide a marginal improvement in the number of cough syrup bottles that can be shipped is a standard package.
