Defending the Theory of Evolution Still Seems Needed

Judith S. Weis, a biology professor who serves as president of the American Institute of Biological Sciences (AIBS) is leading a nationwide effort to "defend" the theory of evolution. Weis leads the effort in the face of what the institute views as opposition and indifference from school boards and government entities.

The Institute believes that the teaching of evolution in America is being diminished by the teaching of creationism as well as by an overall lack of teaching Darwin's theory in high school. "There's nothing that requires schools to teach evolution. Sometimes teachers in high schools just leave it out. However from the point of view of biologists, evolution is the central theory of biology upon which everything is based," said Weis. "Unfortunately, teaching evolution has become a political issue in many parts of the country and AIBS, as a representative of biologists, wanted to be a major force speaking out in favor of its teaching. "

Weis said the institute is working together with the American Geological Institute and the National Association of Biology Teachers and its 80-plus member organizations to address" the political and legislative threats to teaching evolution. In states challenging its teaching, the institute responds by sending letters to school boards and state legislatures, by providing testimony at public meetings and by notifying members and affiliated organizations. AIBS, with more than 80 member societies and 250,000 members, has established an email system enabling scientists and teachers in each state, and member societies, to keep each other informed about threats to the teaching of evolution.

Darwin's theory of evolution holds that living things change and adapt to their environment and that present-day species (including human beings) are descended from earlier species through modification by natural selection. The theory has been accepted by scientists for nearly 100 years, Weis said, and has been refined, extended and strengthened over the years by findings in paleontology and developmental biology. Discoveries in genetics, molecular biology and genomics—all of which provide significant benefits for human health—would not be possible without the underlying knowledge of evolution. And, Weis adds, "modem molecular biology and genomics have increased our understanding of how evolution works." Nonetheless, evolution remains a politically, if not scientifically, controversial issue.

Weis said that this year alone, seven states have had either local or statewide efforts to water down the teaching of evolution, or "balance" it with the teaching of creationism—a religious belief that different species were created separately by a higher power, such as God. "Rarely does anyone now use the word ' creationism, ' because that's too obvious," Weis said. "The current terminology is ' intelligent design. ' "

According to the first paragraph, which of the following statements about the theory or evolution is true？

A．Government entities support AIBS's effort to defend the theory of evolution.

B．School boards oppose AIBS's effort to defend the theory of evolution.

C．AIBS and school boards advocate the teaching of the theory of evolution.

D．The theory of evolution and that of creationism co-exist peacefully in schools.

see smoking as a productivity(生产力) problem. Although some people question whether smoking really affects one's productivity, it has, in fact, been proven that a smoker costs a company more than a non-smoker. According to Professor William Weis, a smoking employee costs his or her employer about $5,700 more a year than a never-smoker. These costs include medical care, lost earnings and insurance. And absence due to smoking breaks is one of the productivity problems, yet it accounts for a great deal of employer costs.

(78)When the issue of smoking at the workplace is discussed, perhaps the most important problem is the health risk that smoking causes to both smokers and never-smokers. It has long been proven that smoking is linked to lung cancer. Now many health experts warn that passive smoking can cause lung cancer and other illnesses in healthy never-smokers. Passive smoking can be defined as exposure to second-hand tobacco smoke in enclosed areas. Anyone who has been with smokers indeed knows that their smoke can cause eye irritation(刺激), coughing, headaches and throat soreness. While eye irritation may seem a small thing to some smokers, it nevertheless is a problem that occurs every workday in offices and break-rooms and can lead to greater health problems. Employees who do not smoke should not be subjected(遭受) to the risks of passive smoking and need to be able to work in a safe environment. Surgeon General Koop states that the right of the smoker stops at the point where his or her smoking increases the disease risk of those occupying the same environment.

A．an employer smokes while working in the office
