问题     The Web sometimes seems like a siren specter that lures us into sitting around like some species of houseplant while our trunk grows abnormally wide. Its【C1】________enticements (诱惑) keep us from doing what we know we should, like, say, making any movement whatsoever or【C2】________foods that do not come packaged in Styrofoam.
    But according to a new research, the Internet can also be something else: a place for helping people keep weight off.
    The new study,【C3】________over a two-and-a-half-year period, found that the more often people logged on to a website, the more likely they were to【C4】________weight loss. Of course, it wasn’t just any old website, but one that investigators at the Kaiser Permanente Centre for Health Research (KPCHR) had designed【C5】________to help people keep the pounds off.
    What made the website work was its mixture of accountability (责任) and【C6】________. Users were asked to log in once a week to【C7】________their weight and the amount of exercise they’d done. If they didn’t log in regularly, they got a little nudge by e-mail, then an【C8】________phone call. Once on the site, users could chat with other【C9】________of the study in a kind of mini-Facebook setting.
    The site was designed to mimic as much as possible what it’s like to be in a weight-loss program that offers【C10】________counseling and group meetings. It wasn’t quite as effective as human-to-human interaction, but it was better than nothing at all.
    A) abundant    F) enter        K) personal
    B) attracts      G) establish     L) separately
    C) automated   H) maintain     M) sociability
    D) conducted   I) obligation     N) specifically
    E) consuming   J) participants   O) warning
【C4】
选项
答案H
解析 动词辨析题。根据空格前的were to和后面的weight loss可以推断。此处应填动词原形。空格后的weight loss意为“减肥”。结合备选项可知，maintain“保持，维持”符合句意，故答案为H)maintain。
