There are two factors which determine an individual's intelligence. The first is the sort

of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual the sort of environment in which he is reared (抚养). If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster (收养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

This selection can be titled ______.

A．Measuring Your Intelligence

B．Intelligence and Environment

C．The Case of Peter and Mark

D．how the Brain Influences Intelligence

Section B – TWO questions ONLY to be attempted

GNT Co is considering an investment in one of two corporate bonds. Both bonds have a par value of $1,000 and pay coupon interest on an annual basis. The market price of the first bond is $1,079？68. Its coupon rate is 6% and it is due to be redeemed at par in five years. The second bond is about to be issued with a coupon rate of 4% and will also be redeemable at par in five years. Both bonds are expected to have the same gross redemption yields (yields to maturity).

GNT Co considers duration of the bond to be a key factor when making decisions on which bond to invest.

Required:

(a) Estimate the Macaulay duration of the two bonds GNT Co is considering for investment. (9 marks)

(b) Discuss how useful duration is as a measure of the sensitivity of a bond price to changes in interest rates. (8 marks)

The difference between biological and physical science is not that one is inexact, the oth

er exact, but in degree of exactness, this being related to the number of variables which must be dealt with simultaneously and the extent to which they can be controlled. In general, the biological sciences must deal with larger errors than the physical sciences; but this is not uniformly true, as the student will realize when he considers the accuracy of meteorological prediction or if he comprehends the meaning of the fact that the structural engineer considers it necessary very often to use a safety factor of two or three hundred per cent. The statistical principles of dealing with error of measurement, or in prediction and generalization, are the same whether the errors are large or small. Statistics is not a means of confusing issues that would otherwise be clear, nor a substitute for obtaining clear answers, but a means of checking and controlling conclusions by providing an estimate of the error to which a conclusion is subject.

What do statistics do for science？

A．They get rid of intuition,

B．They make it more logical.

C．They reduce everything to numbers.

D．They give an idea of the amount of error involved.

Questions are based on the following passage.Romantic love has clear evolutionary roots

Questions are based on the following passage.

Romantic love has clear evolutionary roots but our views about what makes an ideal romanticrelationship can be swayed by the society we.live in.So says psychologist Maureen O'Sullivan from theUniversity of San Francisco.She suggests that humans have always tried to strengthen the pair-bond tomaximise (使最大化) reproductive success.Many societies throughout history and around the world today have cultivated strong pressures tostay married.In those where ties to family and commtmity are strong, lifelong marriages can bepromoted by practices such as the cultural prohibition of divorce and arranged marriages that are seenas a contract between two families, not just two individuals.In modern western societies, however, thefocus on ndividuality and independence means that people are less concerned about conforming to (遵守 ) the dictates of family and culture.In the absence of societal pressures to maintain pair-bonds,O'Sullivan suggests that romantic love has increasingly come to be seen as the factor that shoulddetermine who we stay with and for how long."That's why historically we see an increase in romantic love as a basis for forming long-term relationships," she says.According to O'Sullivan culture also shapes the sorts of feelings we expect to have, and actually doexperience, when in love.Although the negative emotions associated with romantic love-fear of loss,disappointment and jealousy-are fairly consistent across cultures, the positive feelings can vary. "If youask Japanese students to list the positive attributes they expect in a romantic partner, they rate highlythings like loyalty, commitment and devotion," says O'Sullivan. "If you ask American college women,they expect everything under the sun: in addition to being committed, partners have to be amusing,funny and a friend."We judge a potential partner according to our specific cultural expectations about what romanticlove should feel like.If you believe that you have found true romance, and your culture tells you thatthis is what a long-term relationship should be based on, there is less need to rely on social or familypressures to keep couples together, O'Sullivan argues.

What does the author say about people's views of an ideal romantic relationship？

A.They vary from culture to culture.

B.They ensure the reproductive success.

C.They reflect the evolutionary process.

D.They are influenced by psychologists.

Are you planning a vacation？ If you like hot and extremely dry summers, go to Phoenix, Ari

zona. For hot temperatures but lots of rain and thunderstorms, try Miami, Florida. If you want average temperatures and rainfall, St. Louis, Missouri, is the spot. Or if you' re a cold weather fan, head to Fairbanks, Alaska. Its winters are very cold with little precipitation. Each of these cities has a certain type of weather. The average weather for a place over many years is called climate, and in no two places in (he world is it exactly the same. How can this be？

Many things in nature, such as sunshine, temperature, and precipitation, affect climate. Nearness to mountain, oceans, and large lakes affects it loo. Another factor is altitude, or height above sea level. Air cools as altitude increases. So a city at a higher altitude may be colder than one at a lower altitude. Finally, winds affect climate. They move heat and moisture between the oceans and continents. Winds keep the tropics from overheating. They keep the polar regions from getting overly cold.

Climate changes over long periods of time. Some scientists think, for example, that the earth' s climate changed at the time of the dinosaurs. They think the dinosaurs died because of the change. What causes a climate to change？ One possible cause may be changes in the sun. Sunspots, for example, are cool, dark spots that form. on the sun. Sunspots may decrease precipitation on the earth and cause unusually dry periods. Changes in the atmosphere may change climate too. Volcanic eruptions, for instance, release solid particles into the air. These particles may form. a cloud that blocks out the sun ' s heat. Human activity is another cause of climate change. Air pollution and the reduction of forest cover may have long-term effects on climate.

This passage is concerned with things that affect______.

A．precipitation

B．climate

C．altitude

D．sunspots

第6题

The housing market has been for two years propping up consumers' spirits while the rest of

the economy lies exhausted on the floor, still trying to struggle to its feet. According to the National Association of Realtors, the national median existing-home price ended the year at $164,000, up 7.1 percent from 2001. That's the strongest annual increase since 1980.

Although residential real estate activity makes up less than 8% of total U.S. GDP, a housing market like this one can make the difference between positive and negative growth. Most significantly, consumer spending is 66% of GDP, and the purchase of a new home tends to have an "umbrella effect" on the homeowner's spending as he has to stock it with a washer/ dryer, a new big-screen TV, and maybe a swing set for the yard.

The main factor in housing's continued strength is a classic economic example of zero-sum boom: the persistent weakness everywhere else. As the 2003 recovery continues to be more forecast than reality. Falling stock prices raised investor appeal for U.S. Treasury Bonds, which in turn, allowed most interest rates to drift even lower. But there are not many signs that there's a bubble ready to burst.

December's new record in housing starts, for example, was nicely matched by the new record in new home sales. If you build it, they will buy and even if an economic pickup starts to reduce housing's relative attractiveness, there's no reason why modest economic growth and improved consumer mood can't help sustaining housing's strength. "The momentum gained from low mortgage interest rates will carry strong home sales into 2003, with an improving economy offsetting modestly higher mortgage interest rates as the year progresses", said David Lereah, chief economist at the National Association of Realtors.

Just as housing has taken up much of the economic slack for the past two years, both as a comforting investment for fretting consumers and a driver of consumer spending itself, a big bump elsewhere in the economy in 2003 could be housing's downfall. If stocks roar back this spring, capital inflows could steal from the bond market, pushing up long-term interest rates. Or Alan Greenspan and the Fed could do the same to short-term rates, as a way to hit the brakes on a recovery that is heating up too fast. In other words, if everything possible goes wrong for housing, homeowners should have plenty to compensate them in terms of job security and income hikes.

The author draws a sharp contrast between the housing market and the rest of the economy so as to show

A．the boom of real estate activity.

B．the statistics on home prices.

C．the role of housing market.

D．the degree of consumer spirits.
