[填空题]According to a survey in the US, age and gender have great influence on the frequency of heart attacks.
Less than 6% of all heart attacks occur in the 29 to 44 age group. The number of women who suffer heart attacks in this group is negligible(微不足道的)—only 3000 per year, compared to 123,000 men.
However the proportion of men and women with heart attacks rises dramatically between 45 and 64, with over half a million per year. Over 420,000 men a year in this age group have heart attacks. The incidence amongst women increases— women have one heart attack for every three men in this age group.
Over the age of 65, the number of men suffering heart attacks only increases slightly. However there is a huge increase in the number of women with heart attacks—they comprise over 40% of all victims.
From the survey, it is clear that men are more likely to be the victims of heart attacks at all ages, but women are in-creasingly likely over the age of 60.

[填空题]A CONDENSED EMPLOYEE LIFE CYCLE
An employee life cycle is the steps the employees go through from the time they enter a company until they leave. Often Human Resources professionals focus their attention on the steps in this process in hopes of making an impact on the company’s bottom line. That is a good thing for them to do. Their goal is to reduce the company’s cost per employee hired. Employees are one of a company’s largest expenses these days. Unlike other major capital costs (buildings, machinery, technology, etc.) human capital is highly volatile. You, as a manager, are in a key position to reduce that volatility using the condensed employee life cycle of HIAR ( pronounced hire)--Hire, Inspire, Admire, Retire.
Hire: This first step is probably the most important. It is important to hire the best people you can find. (8) The cost of replacing a bad hire far exceeds the marginal additional cost of hiring the best person in the first place.
Inspire: Once

[单项选择]Being smart is the most expensive thing we do. Not in terms of money, but in a currency that is vital to all living things: energy. One study found that newborn humans spend close to 90 percent of their calories on building and running their brains. (Even as adults, our brains consume as much as a quarter of our energy.) If, during childhood, when the brain is being built, some unexpected energy cost comes along, the brain will suffer. Infectious disease is a factor that may rob large amounts of energy away from a developing brain. A great deal of research has shown that average IQ varies around the world, both across nations and within them.
Higher IQ predicts a wide range of important factors, including better grades in school, a higher level of education, better health, better job performance, higher wages, and reduced risk of obesity. So having a better understanding of variations in intelligence might yield a greater understanding of these other issues as well.

C. show the history of less infectious diseases there.
D. show that people there are slimmer than those with lower IQ.
