问题     Engaging in a hobby like reading a book, making a patchwork
quilt or even playing computer games can delay the onset of
dementia, a US study suggests. Watching TV but does not【M1】______
count—and indeed spending significant periods of time in front of
the box may speed up with memory loss, researchers found.【M2】______
Nearly 200 people aged 70 to 89 with mild memory problems were
compared to a group who had no impairment. The researchers【M3】______
from the Mayo Clinic in Minnesota asked the volunteers about
their daily activities within the past year and how mental active【M4】______
they had been between the age of 50 to 65. Those who had during
middle age busy reading, playing games or engaging in craft【M5】______
hobbies like patchworking or knitting was found to have a 40%【M6】______
reduced risk of memory impairment. In later life, those same
activities reduced the risk by between 30 and 50%. Those who
watched TV for less than 7 hours a day were also 50% more likely【M7】______
to develop memory loss than those who spent longer than that
staring at the screen.
    "This study is exciting because it demonstrates that age does【M8】______
not need to be a passive process," said study author and
neuroscientist Dr Yonas Geda. "By simply engaging in cognitive
exercise, you can protect against future memory loss. Of course,
the challenge with this type of research is what we are relying on【M9】______
past memories of the participants, therefore we need to conform【M10】______
these findings with additional research."

选项

答案more一less

解析 语篇错误。本文在开头第二句就提到“看电视起不到这个作用(减缓痴呆症)”,而本句说“与看电视超过7小时的人比,看电视少于7小时的人失忆的可能性要高50%”,显然与开头提到的研究结果相悖,故应将more改为less,表示看电视少于7小时的人患失忆的可能性要低。
