Homing pigeons are placed in a training program from about the time they are twenty-eight days of age. They are taught to enter the cage through a trap and to exercise above and around the loft(鸽棚) , andgradually they are taken away for short distances in willow baskets andreleased. They are then expected to find their way home in the shortestpossible time。
A few days ago, on 15th April, 2015, a terrified riot aimed at foreign residents happened in South Africa. For years, South Africa was named by its multi-racial environment and well-developed in economics. It is also called rainbow country. However, the whole riot is not happening suddenly and unreasonably. This essay is going to analyze the reasons that South Africa can become the second largest economy in Africa and also the reasons why there are such problem happened in South Africa. Finally a conclusion will be drawn.
In their training flights or in actualraces, the birds are taken to prearranged distant points and released to findtheir way back to their own lofts. Once the birds are liberated, their owners,who are standing by at the home lofts, anxiously watch the sky for the returnof their entries. Since time is of the essence, the speed with which the birdscan be induced to enter the loft trap may make the difference between gaining awin or a second place。
Become the First Class in Africa
The head of a homing pigeon iscomparatively small, but its brain is one quarter larger than that of theordinary pigeon. The homing pigeon is very intelligent and will persevere tothe point of stubbornness; some have been known to fly a hundred miles offcourse to avoid a storm。
Once upon the time, South Africa was one of the British colonies. Like many other colonies, British warlords not only brought humiliation but also great opportunities of industrialization. After the year 1866, gold mines and diamond mines were found in South Africa. Gold and diamond became the main export products and brought great amount of wealth to South Africa. Besides, after the establishing of the Republic of South Africa, the development in manufacturer, especially steel-making, led to huge economic growth to the country. The whole manufacturer industry made 16% of the nominal GDP in 2008. Unlike Venezuela, other industries like agriculture, fishery and service industry are also well-developed in South Africa compared with other African countries. Multi-race, especially the high percentage of white residents plays the very important role of the economic development of South Africa rather than other African countries.
Some homing pigeon experts claim thatthis bird is gifted with a form of built-in radar that helps it find its ownloft after hours of flight, for hidden under the head feathers are two verysensitive ears, while the sharp, prominent eyes can see great distances indaytime。
Problems of South Africa
Why do homing pigeons fly home? They arenot unique in this inherent skill; it is found in most migratory birds, inbees, ants, toads, and even turtles, which have been known to travel hundredsof miles to return to their homes. But in the animal world, the homing pigeonalone can be trusted with its freedom and trained to carry out the missionsthat people demand。
However, behind the great success, problems in South Africa are even more serious.
1. This passage is mainly about_______。
First and the most important problem is the high unemployment rate. In 2010 the official number was 24.2% which means based on the official statistical office there were 24.2% of labors could not find jobs in labor market. Actually the official number just counted those who were willing to work but not those who had already given up finding a job. In fact, there were only 41% of the whole population in labor age that were working in 2010. The cheerful social welfare for unemployed people even encouraged people not to work, which also made government’s burden heavier.
A. homing pigeons and their training
Secondly, the great distinguish between black people and others also aggravates the hate in normal people’s heart. Even if Nelson Mandala pushed very hard on the equality between black and white, in deep side of people’s mind blacks are still poor,dirty and uncivilized. In South Africa, 53.8% of people were under the poverty line and the Gini coefficient was 0.62 in 2011. The majority of those poor people are black. And they are also the majority of the riot happened recently.
B. how to buy a homing pigeon
Thirdly, in South Africa, illegal immigration is also very serious, especially in contraction,tourism and housing service industry. Because the salary of those illegal immigration are generally lower than local people. This makes the employment opportunities even fewer than before. Although the immigration policy have been more and stricter since 1994, there are supply and demand, then there are market. Local residents hate rich people but hate foreigners even more.
C. protection of homing pigeons againstthe threat of extinction
Forth is about the labor union. The labor union in South Africa asked that the growth rate of wage should be greater than inflation rate which is around 5%. They usually hold big campaigns and strikes. Finally government rose the growth rate of wages to 7.5%but only the members of labor union can enjoy newest salary. Those nonmember people are usually farmers and fishers who are all local residents. So the gap of income level between the each industry amplifies as time passes by, so does the unsatisfactory inside poor people’s mind.
D. liberation of homing pigeons
2. According to the passage, whathappens to homing pigeons when they are about a month old?
Every time a riot or a campaign happens, there must be some reasons behind it and these reasons are usually not made by the people but the government. Governments tend to blame on the chaos made by people and regard them as criminals. But try to imagine who would like to go on the street fight against a well-organized government rather than stay at home enjoy their happy life. The people are just sometimes irrational so that they think violence is the only way to solve the problem and force the government to become well-organized enough so that they can have happy life. If government cannot see through it and try to solve the problem,then the problem is always problem and violence will happen once and once again.Now what South African government should do is to figure out a way to decrease the unemployment rate instead of just making statement of strongly denunciation of the criminal.

C. the texture of the feathers D. thesize of the brain
4. The author mentions all of thefollowing attributes that enable a homing pigeon to
return home EXCEPT_______。

C. To compare their home-findingabilities with those of homing pigeons。
D. To interest the reader in learningabout other animals。
Are some people born clever, and othersborn stupid? Or is intelligence developed by our environment and ourexperiences? Strangely enough, the answer to both these questions is yes. Tosome extent our intelligence is given us at birth, and no amount of specialeducation can make a genius out of a child born with low intelligence. On theother hand, a child who lives in a boring environment will develop hisintelligence less than one who lives in rich and varied surroundings. Thus thelimits of a person's intelligence are fixed at birth, but whether or not hereaches those limits will depend on his environment. This view, now held bymost experts, can be supported in a number of ways。
It is easy to show that intelligence isto some extent something we are born with. The closer the blood relationshipbetween two people, the closer they are likely to be in intelligence. Thus ifwe take two unrelated people at random(任意的) from the population,it is likely thattheir degrees of intelligence will be completely different. If on the otherhand we take two identical (完全相同的) twins they will very likely be asintelligent as each other. Relations like brothers and sisters, parents andchildren, usually have similar intelligence, and this clearly suggests that intelligencedepends on birth。
Imagine now that we take two identicaltwins and put them in different environments. We might send one, for example,to a university and the other to a factory where the work is boring. We wouldsoon find differences in intelligence developing, and this indicates thatenvironment as well as birth plays a part. This conclusion is also suggested bythe fact that people who live in close contact with each other, but who are notrelated at all, are likely to have similar degrees of intelligence。

A. To some extent, intelligence is givenat birth。

In the last 12 years total employment in the United Statesgrew faster than at any time in the peacetime history of any country – from 82to 110 million between 1973 and 1985 – that is, by a full one third. The entiregrowth, however, was in manufacturing, and especially in no – blue-collar jobs… This trend is the same in all developedcountries, and is, indeed, even more pronounced in Japan. It is therefore highlyprobable that in 25 years developed countries such as the United States andJapan will employ no larger a proportion of the labor force I n manufacturingthan developed countries now employ in farming – at most, 10 percent. Today theUnited Statesemploys around 18 million people in blue-collar jobs in manufacturingindustries. By 2010, the number is likely to be no more than 12 million. Insome major industries the drop will be even sharper. It is quite unrealistic,for instance, to expect that the American automobile industry will employ morethan one –third of its present blue-collar force 25 years hence, even thoughproduction might be 50 percent higher。
If a company, an industry or a country does notin the next quarter century sharply increase manufacturing production and atthe same time sharply reduce the blue-collar work force, it cannot hope toremain competitive – or even to remain “developed。” The attempt to preservesuch blue – collar jobs is actually a prescription for unemployment…
This is not a conclusion that Americanpoliticians, labor leaders or indeed the general public can easily understandor accept. What confuses the issue even more it that the United Statesis experiencing several separate and different shifts in the manufacturingeconomy. One is the acceleration of the substitution of knowledge and capitalfor manual labor. Where we spoke of mechanization a few decades ago, we nowspeak of “robotization “ or “automation。” This is actually more a change interminology than a change in reality. When Henry Ford introduced the assemblyline in 1909, he cut the number of man – hours required to produce a motor carby some 80 percent in two or three years –far more than anyone expects toresult from even the most complete robotization. But there is no doubt that weare facing a new, sharp acceleration in the replacement of manual workers bymachines –that is, by the products of knowledge。

What does the future hold for the problem ofhousing? A good deal depends, of course, on the meaning of “future”. If one isthinking in terms of science fiction and the space age, it is at least possibleto assume that man will have solved such trivial and earthly problems ashousing. Writers of science fiction, from H.G. Wells onwards, have had littleto say on the subject. They have conveyed the suggestion that men will live ingreat comfort, with every conceivable apparatus to make life smooth, healthyand easy, if not happy. But they have not said what his house will be made of.Perhaps some new building material, as yet unimagined, will have beendiscovered or invented at least. One may be certain that bricks and mortar(泥灰，灰浆) will long have gone outof fashion。
But the problems of the next generation or twocan more readily be imagined. Scientists have already pointed out that unlesssomething is done either to restrict the world’s rapid growth in population orto discover and develop new sources of food (or both)， millions of people willbe dying of starvation or at the best suffering from underfeeding before thiscentury is out. But nobody has yet worked out any plan for housing thesegrowing populations. Admittedly the worst situations will occur in the hottestparts of the world, where housing can be light structure or in backward areaswhere standards are traditionally low. But even the minimum shelter requiresmaterials of some kind and in the teeming, bulging towns the low-standard“housing” of flattened petrol cans and dirty canvas is far more wasteful ofground space than can be tolerated。
Since the war, Hong Konghas suffered the kind of crisis which is likely to arise in many other placesduring the next generation. Literally millions of refugees arrived to swell thealready growing population and emergency steps had to be taken rapidly toprevent squalor(肮脏)and disease and the spread crime. The city is tacklingthe situation energetically and enormous blocks of tenements(贫民住宅)are rising at anastonishing aped. But Hong Kong is only onesmall part of what will certainly become a vast problem and not merely ahousing problem, because when population grows at this rate there areaccompanying problems of education, transport, hospital services, drainage,water supply and so on. Not every area may give the same resources as Hong Kong to draw upon and the search for quicker andcheaper methods of construction must never cease。
