问题     One of the most important results of research into ageing has been to pinpoint the significance of short-term memory. This faculty is easily (1)_____ as ageing advances. What seems to (2)_____ is that information is received by the brain, (3)_____ scans it for meaning in order to decode it at some future time. It looks as if the actual (4)_____ of the short-term memory itself may not change too much (5)_____ age. A young man and a man in his late fifties may (6)_____ be able to remember and repeat a(n) (7)_____ of eight numbers recited to them. But what (8)_____ change is that when the older man is asked to remember anything (9)_____ between the time he is first given the numbers to memorize and the time he is asked to (10)_____ them, he will be much less likely to remember the (11)_____ numbers than the young man. This is because the scanning stage is more easily (12)_____ by other activities in (13)_____ people.
    In (14)_____ living one experiences this as a fairly minor (15)_____—a telephone number forgotten while one looks (16)_____ an area code, or the first part of (17)_____ street directions confused with the last because the last ’turn lefts’ and ’turn rights’ have interfered (18)_____ remembering the first directions. In more formal learning, however, the (19)_____ of short-term memory is more than just a mild social embarrassment. It can be a serious bar to further (20)_____ or indeed to any progress at all.

选项 A、else
B、more
C、particular
D、special
答案A
解析 第一处空白处谈到短期记忆能力"is easily disturbed"，随后又谈到老年人和年轻人记忆的容量本身是相同的，可以看出老年人和年轻人的差别在于对干扰的耐受力不同。而本空白处下文谈到"is more easily…by other activities"，由此可以看出，本空白处应该指在记忆数字的间隙让他们记忆其他东西，从而形成干扰。故"else"正确。"more"放在这里不合适，因为文中强调的是其他事物的记忆会对原来的记忆造成干扰，而不是强调是否能记更多的事情。particular和special都没有"其他"的含义，不正确。
