单选题Osteoporosis used to be called "the silent disease" because its victims didn" t know they had it until it was too late and they suffered a bone fracture. Today, doctors can identify osteoporosis early. Improved understanding of the disease has also led to new treatments and strategies for preventing the disease altogether. For post-menopausal women, the most common medical response to osteoporosis is hormone replacement therapy. Boosting estrogen levels strengthens the entire skeleton and reduces the risk of hip fracture. Unfortunately, it sometimes causes uterine bleeding and may increase the risk of breast cancer. To bypass such side effects, researchers have developed several alternative treatments. Synthetic estrogens called Selective Estrogen Receptor Modulators(SERMs)emulate estrogen with slight modifications. Another drug, alendronate, reduces spine, hip and wrist fractures by 50 percent. Researchers have even developed a nasal spray called calcitonin. Each of these alternatives has trade-offs, however. Patients must talk with their doctors to decide which therapy is best for them. The ideal way to address osteoporosis is by adopting a healthy lifestyle. And the best time to do this is in childhood, when most bone mass is accumulated. Because bodies continue building bone until about age thirty, some experts believe that women in their twenties can still increase their bone strength by as much as 20 percent. Calcium, which is available in low-fat dairy foods and dark green vegetables, is essential for preventing osteoporosis. So is vitamin D, which aides calcium absorption. Vitamin D comes from sunlight, but dietary supplements may be helpful in northern climates and among those who don"t get outside. The final component is regular moderate exercise because bone responds to the needs that the body puts on it. These are the simple steps that can help make "the silent disease" truly silent.

单选题(77)In what now seems like the prehistoric times of computer history, the early post-war era (战后时期) there was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are facing with a less dramatic but also less foreseen problem. People tend to be over-trusting(过分信任) of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction( 失灵 ). (78)Obviously, there would be no point in investing(投入) in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.
