He landed in this country when he was 4 years old without a word of English, and there he has recently graduated with honors from Loyola Academy.
An immigrant kid whose family rents an apartment in a city two-flat, he attended the North Shore school with full scholarship. All the aunts and uncles were so proud that they made their way from the old country or from various comers of this country to celebrate his graduation.
A debate is raging about whether immigrant children first should be taught English, then their other subjects; or whether they should be taught other subjects in their native tongue as they are more gradually introduced to English over two to three years.
California voters recently banished the gradual approach—bilingual education—in favor of immersion in the English language. The Chicago Public Schools in February put a three-year deadline on moving into all English classes in most cases. But that was never an issue for this

Optimists Really Do Live Longer,Say Scientists
1 For the philosopher Arthur Schopenhauer optimism was fundamentally wrong,banal and corrupting while the father of psychoanalysis Sigmund Freud simply declared it to be neurotic.
2 Experience shows that looking on the bright side of life does have advantages and recent scientific evidence points to the positive mindset as being beneficial to health.In other words,optimists live longer.
3 That was the conclusion reached by experts at the Mayo Clinic in the US State of Minnesota who evaluated answers given by people to a set of questions in the 1960s.Of the 729 candidates,200 had died and according to scientists,there were a disproportionate number of pessimists among them.
4 Ten points more on the pessimism scale-that was the difference between"slightly pessimistic"and "averagely pessimistic”-were enough to boost a person's chances of dying by 19 percent,according to the study by prominent psychologist Martin Seligman of the University of Pennsylvania.
5 The study does not say why pessimists die.But an older survey taken among children in San Francisco and Los Angeles makes it clear that personal attitude towards the world is a key factor in the ion- gevity equation.
6 The latest evidence to support the theory that optimists tend to cope better with illness of all kinds has been provided by Professor Raif Schwarzer of Berlin's Free University who questioned 600 heart and lung patients.His conclusion:Optimists recover more swiftly from operations than their pessimistic counter- parts,tend to be happier after treatment and return to work more swiftly.
7 There have been suggestions that optimists do not stay healthier but rather turn into optimists later because they enjoy good health.Numerous surveys have taken into account a person's state of health at the outset and the effect remains the same.
8 Studies have shown that optimists do not blind themselves to reality either.They thus interpret it in a positive way."Sublimating and denying things tend to alter reality but illusions are a way of seeing reality in the best light,"said Californian psychology professor Shelley Taylor.
9 German science journal Buld der Wissenschaft，which carries a major article on the topic in its current March issue,commented on"the right attitude"to having a tumor.
10 It seems psychotherapy can go some way towards extending the life span and life quality of a sick person although a complete recovery using psychological technique alone is unlikely.
1 1 Doctors like,however,to point to the example of US cycling professional Lance Armstrong,who was seriously ill with cancer,but whose unshakeable optimism helped him to take the top trophy twice at cycling's premier Tour de France.
1 2 The magazine also quoted a study by Sheldon Cohens of the Carnegie-Mellon-University in Pittsburgh: 420 volunteers were deliberately infected with strains of various common cold viruses.A day later checks were carried out to see who had caught a cold.
13 The results showed that in the case of people who had.satisfactory,long-term relations with friends, neighbors or colleagues, the virus was less likely to trigger a cold.Of people with three or fewer firm relation- ships 62 percent became ill compared with only 35 percent of those who had six or more close human links.
An optimist does not necessarily try______.
A.to avoid unpleasant things in life
B.in looking on the bright side of life
C.less likely to catch cold
D.how one looks on life
E.to be unhappy all the time
F.more likely to get cancer
