There’s no easy answer to this question. Your genetic makeup, the physical traits that get passed down1 to you from your parents, plays a big part in determining your size and weight.

    ___1___ But if your parents are smaller than average, you may want to rethink that professiona1basketball career!2

    The same goes for your body type.3 Have you ever heard someone say a person is “big boned4”? It’ s a way of saying a person has a large frame, or skeleton. Big bones usually weigh more than small bones. ____2 ___

    Like your height or body type, your genes have a lot to say6 about what your weight wi11 be. But that"s on1y part of the story. Being overweight can run in someone"s farnily, but it may not be because of their genes.7___3__ And even though some kids gain weight more easily than others, when they eat right and exercise , most kids can be a hea1thy and happy weight that"s right for them. It" s true — the way you live can change the way you look.

    How much you weigh is a ba1ance between calories you eat and the calories you use.

    ___4___If you spend your free time watching TV, your body won’t use as many calories as it would if you played basketball, skated, or went for a walk. If you are in balance, your weight will stay right for you as you grow. But if you eat more and exercise less, you may become overweight. ___5__

Privacy Worry May Keep HIV2¹ Patients from Therapy

    Patients infected with HIV are often concerned about² the confidentiality of their HIV-positive status. In fact, some patients are so worried that they will actually give up treatment to prevent the release of this information, according to a report published in the August issue of AIDS Care.

    Dr. Kathryn Whetten-Goldstein and colleagues from DukeUniversity,Durham, North Carolina³, studied the confidentiality issues of 15 HIV-infected patients from ruralNorth Carolinalocations. They were divided into groups designed to explore their attitudes toward, and experiences with, breaches in confidentiality.

    “The fear of a breach in confidentiality is definitely affecting the care that HIV-infected patients receive,”  Whetten-Goldstein said. “Most studied patients had experienced or knew someone who had experienced a breach in confidentiality.”

    “Two types of breaches occurred, ”Whetten-Goldstein noted. “The first was a more obvious type of breach. One example was a nurse who told her child that her patient was HIV-positive out of concern that her child would play with the patient’s child.⁴”

     “The other type of breach was more subtle, one that providers might not consider breaches, ⁵” Whetten-Goldstein explained. “This type of breach involves providers talking about a patient’s HIV status without the patient’s knowledge of the interaction.”

    “The law allows the sharing of information between providers within the same institution, but patient’s consent must be obtained before providers at different institutions can share information,” she pointed out.

    “Patients in the study wanted providers to tell them when they are going to share information with other providers and why it is being done,” Whetten-Goldstein said. “They also felt that providers should be punished when a breach occurs.”

    “However, because patients are often reluctant to seek legal action which may further expose their status, they felt that the system should regulate itself,” she added.

词汇：

privacy /ˈpraɪvəsi,ˈprɪvəsi/ n.隐私,秘密
breach /bri:tʃ/n.破坏,违反
therapy /"θerəpɪ/ n.疗法,治疗
consent /kən"sent/ n.答应,允许
confidentiality /ˌkɒnfɪˌdenʃiˈæləti/ n.保密性
regulate /"reɡjʊleɪt/ vt.调整

注释：

1.HIV (human immunodeficiency virus):人类免疫缺陷病毒
2.be concerned about:为……而担心（忧虑、烦恼）
3. North Carolina：(美国）北卡罗来纳州
4.One example was... with the patient’s child.例子之一就是某个护士由于担心自己的孩子会与病人的孩子一起玩,所以就告诉自己的孩子,这个病人是HIV阳性的病人。本句中who 至the patient’s child 是nurse 的定语从句,其中that her patient was HIV-positive又是told的宾语从句；out of concern (出于担心）是介词短语,作told的状语；而that her child would play with the patient’s child 则是concern的同位语从句。
5.one that providers might not consider breaches：即医生可能不认为是泄露个人机密的一类。one是代词,代替type,作the other type的同位语，that至breaches是one的定语从句，that在定语从句中作consider的宾语，breaches是宾语补足语。而provider则是指美国经保险公司认可为投保人看病的医生。

Quite a few patients will firmly defend their own right if such a breach occurs

Beyond the Pap

    Scientists have known for some time that virtually all cases of cervical cancer are triggered by a family of viruses called human papillomavirus, or HPV. ¹Most women who become infected with HPV are able to shake off the virus and suffer no apparent long-term consequences to their health. But a few women develop a persistent infection that can, for reasons that are not entirely clear, eventually lead to cancerous changes in the cervix.

     Now researchers at the Digene Corp of Beltsville,Maryland, have developed a test that detects an active HPV infection by looking for its genetic byproducts in the vagina. The HPV test was better than the standard Pap test at finding cervical cancer at any stage, according to two studies published this month in the Journal of the American Medical Association. So far, so good. Unfortunately, the test"s false-positive rate—how often it indicated that there was a problem when none existed was almost twice as high as that for the Pap smear.² In these cases, a biopsy of the woman’s cervix showed no sign of disease.

    And that’s the crux of the problem. How many women should undergo what is, when it comes right down to it, unnecessary treatment to find a few more cases of cervical cancer?³ Shouldn’t health officials focus instead on making sure that more women undergo regular Pap-smear examinations? After all, Pap smears, though far from perfect, have helped dramatically lower the death toll from cervical cancer taking it from the No. 1 cause of death due to cancer in American women to the 10th.

    Complicating matters is the fact that HPV is a very common infection. In some parts of theU.S.as many as half of all women under age 35 have an active case. Yet 99 out of 100 women who are HPV-positive will never get cervical cancer, estimates Dr. Joanna Cain, vice president of theAmericanCollegeof Obstetricians and Gynecologists. “If those 99 women live their lives as if they’re going to develop cancer”, she says, “we’re not necessarily doing them any good.”

    At present, the HPV test is approved in theU. S.only to help resolve ambiguous results from a Pap-Smear test. Many gynecologists believe that HPV will eventually replace the pap. But they’re not willing to abandon it without a lot more detailed information and neither should you.
