问题     As the baby-boomer generation contemplates the prospect of the Zimmer frame there has never been more interest in delaying the process of ageing. One consequence has been a(n) 【C1】______rise in the popularity of brain-training games. But how 【C2】______ really is a daily dose of cryptic crossword?
    Robert Wilson, a neuropsychologist at Rush University in Chicago, and his colleagues decided to【C3】______out, 【C4】______following a group of people without dementia. Participants were asked to【C5】______how frequently they engaged in cognitively【C6】______activities. The researchers were looking for such things as reading newspapers, books and magazines, 【C7】______ challenging games like chess, listening to the radio and watching television, and 【C8】______ museums.
    The good news, as they report in Neurology, is that【C9】______activity of this sort seems to slow the rate of【C10】______decline in those without cognitive【C11】______. The bad news is that in those who do then develop Alzheimer’ s disease it is associated with a more rapid【C12】______decline.
    What seems to be happening is that cognitive stimulation helps【C13】______the effect of theneurodegenerative lesions associated with dementia. It does not,【C14】______, make them go away. They continue to【C15】______, so that when the disease does eventually take【C16】______there are more of them around than there otherwise would be, which results in a more【C17】______cognitive fall off. That is not a message of despair, 【C18】______, because the length of time someone suffers from dementia is thus 【C19】______ and their healthy life prolonged. So the message is,【C20】______on with the crosswords.
【C18】
选项 A、until
B、though
C、unless
D、if
答案B
解析 考查逻辑关系。空格前阐述：当疾病最后开始发作时，带来的损害比原来的更多。空格后阐述：这并不是令人绝望的消息。据此推知，前后为转折关系，因此正确答案为B．though“尽管，虽然”。其他三项均不符合题意。
