Sickness at work

Small firms are counting the cost of sickness among employees. Research estimates that illness cost small businesses in Britain a month and a half in lost (21) last year. A recent (22) of more than 1,000 small and medium enterprises revealed that last year the average small business lost around 42 days through staff phoning in sick, and that this had a serious (23) on 27 per cent of smaller companies.

Just over one in ten employees took time off for seven days in a

(24) Of these, 9.5 per cent were ill for a week on more than one occasion. In Britain, employees can take sick (25) for up to a week before they have to produce a medical certificate. Owner-managers were far less likely to be off sick than their staff: 3.3 days on average, compared with the 10 days taken by employees.

The head of the research team said, 'The most common (26) of absence was minor illness, such as colds or flu, but back strain, fractures and the like (27) for very nearly as much. Of greater (28) is that more that 40 per cent of employers felt that their employees' sickness may not have been genuine.'

Employers can do more to protect themselves by drawing up adequate (29) of employment that outline the company's sick pay (30) Enhanced sick pay is then at the employer's discretion.

Elizabeth Hazen and Rachel Brown copatented one of the most widely acclaimed wonder drugs
of the post-Second World War years. Hazen and Brown's work was stimulated by the wartime need to find a cure for the fungus(真菌类) infections that afflicted many military personnel. Scientists had been feverishly searching for an antibiotic toxic enough to kill the fungi but safe enough for human use, since, unfortunately, the new "wonder drugs" such as penicillin and streptomycin(链霉素) killed the very bacteria in the body that controlled the fungi. It was to discover a fungicide without that double effect that Brown, of New York State's Department of Health Laboratories at Albany, and Hazen, senior microbiologist at the Department of Health in New York, began their long-distance collaboration. Based upon Hazen's previous research at Columbia University, where she had built an impressive collection of fungus cultures, both were convinced that an antifungal organism already existed in certain soils.

They divided the work. Hazen methodically screened and cultured scores of soil samples, which she then sent to her partner, who prepared extracts, isolated and purified active agents, and shipped them back to New York, where Hazen could study their biological properties. On a 1948 vacation, Hazen accidentally collected a clump of soil from the edge of W.B. Nourse's cow pasture in Fauquier County, Virginia, that, when tested, revealed the presence of the microorganisms. In farm owner Nourse's honor, Hazen named it Streptomyces noursci , and within a year the two scientists knew that the properties of their substance distinguished it from previously described antibiotics. After further research they eventually reduced their substance to a fine, yellow powder, which they first named "fungiciden", then renamed "nystatin"(to honor the New York State laboratory) when they learned the previous name was already in use. Of their major discovery, Brown said lightly that it simply illustrated "how unpredictable consequences can come from rather modest beginnings."

What is the main topic of the passage?

A.The lives of Hazen and Brown.

B.The development of a safe fungicide.

C.The New York State Department of Health.

D.The development of penicillin.

Exercise Cuts Cancer Deaths in Men

Men who exercise often are less likely to die from cancer than those who 【51】______, new research published in the British Journal of Cancer revealed yesterday.

A team of scientists from the Karolinska Institute in Sweden looked 【52】______ the effect of physical activity and cancer risk in 40,708 men aged 【53】______ 45 and 79.

The seven-year study found that men 【54】______ walked or cycled for at least 30 minutes a day had a 34 percent lower 【55】______ of dying from cancer than the men who did less exercise or nothing at all. 【56】______ the period studied, 3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour's walking 【57】______ cycling a day increased survival among these men by 33 percent.

The researchers surveyed men from two counties in central Sweden about their lifestyle. and the amount of 【58】______ activity they were usually doing. They then scored these responses and compared the results with data on cancer diagnosis and death officially recorded in a central cancer registry(登记簿) over a seven-year 【59】______.

Lead author, Professor Alicja Wolk, said: "These results clearly show for the first time the effect that very simple and basic daily 【60】______ such as walking or cycling has in reducing cancer death risk in middle-aged and elderly 【61】______".

Dr. Lesley Walker, director of cancer information at Cancer Research UK, said: "This study gives us a clear indication that men who exercise are less 【62】______ to die from cancer, and that they are more likely to 【63】______ the disease if they get it. It's not entirely clear from this study what role exercise plays in preventing 【64】______ in men, but we do know that a healthy lifestyle. can prevent up to half of all cancers—and 【65】______ exercise forms a key part of this".

A.didn't

B.don't
