Diet, Alcohol Linked to Nearly One Third of CancersDiet is second only to tobacco as a leading (1) of cancer and，along with alcohol，is responsible for nearly one third of cases of the disease (2) developed countries, a leading researcher said on Tuesday.Dr. Tim Key, of the University of Oxford, told a cancer conference that scientists are still discovering how certain foods contribute to (3) , but they know that diet, alcohol and obesity (4) a major role."Five percent of cancers could be avoided (5) nobody was obese," he said.While tobacco is linked to about 30 (6) of cancer cases, diet is involved in all estimated 25 percent and alcohol (7) about six percent.Obesity raises the (8) of breast, womb, bowel and kidney cancer, while alcohol is known to cause cancers of the mouth, throat and liver. Its dangerous impact is (9) when combined with smoking.Key told the meeting of the charity Cancer Research UK (10) other elements of diet linked to cancer are (11) unknown but scientists are hoping that the EPIC study, which is comparing the diets of 500, 000 people in 10 countries and their risk of cancer, will provide some (12) Early results of the study have revealed that Norway, Sweden and Denmark have the (13) consumption of fruit and vegetables among European countries while Italy and Spain have the highest.

Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most (51) to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (52) increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil-workers (53) the .U.S.A. and Europe. It has brought in workers from many countries, (54) South Korea and Japan.In view of the difficult living and working (55) in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can (56) at least twice as much money in the Middle East as they can in their own country, and this is a major (57) .Sometimes a disadvantage has a compensating (补偿) advantage. For example, the (58) living conditions often lead to increased friendship when workers have to (59) on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the (60) of entertainment facilities. The work is often complex and full of problems but this merely (61) greater challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which (62) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on (63) , so it is not easy for them to plan ahead with great confidence. This is to be (64) since no country welcomes a large number of foreign workers as permanent residents. In any (65) , migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive. 52().
