问题 单项选择题

有专家建议,为盘活土地资源,有效保护耕地,让农民像城市人一样住进楼房是个不错的选择,这样就可以将农民现有的住房“叠起来”,从而节省大量土地资源。 以下哪项如果为真,最能削弱上述专家的观点( )

A.由于农民的生产生活习惯,他们大多表示不愿住楼房

B.建楼房消耗的资源与建现有的农民住房消耗的资源差不多

C.有农民表示,即使搬进楼房居住,他们也不会将现有的房子拆掉

D.农民住进楼房后远离田地,影响农业生产,会从效益上降低土地资源的利用

答案

参考答案:C

解析: 专家的建议正是建立在农民住房挤占耕地这一事实基础之上的,那么如果农民搬进楼房之后也不拆掉现有的房子,也就直接打击了专家立论的基础。故选C。

Exercising to music pumps up brain power


If music makes you smarter, and exercise helps brain function, can exercising to music really boost brainpower Some researchers said it can. Volunteers who listened to Vivaldi’s "Four Seasons" while working out on a treadmill did much better on a test of (1) ability than when they exercised without music, a team (2) Ohio State University found.
"Evidence suggests that exercise improves the (3) performance of people with coronary artery (4) ," said psychologist Charles Emery, who led the study.
"And listening to music is (5) to enhance brainpower. We wanted to put the two results together," Emery (6) in a statement.
Writing in the latest issue of the journal Heart & Lung, Emery and (7) said they studied 33 men and women taking (8) in a cardiac rehabilitation program after having bypass (9) , angioplasty or other procedures to treat clogged arteries.
The (10) said they felt better emotionally and mentally after working out (11) or without the music. But their improvement on the (12) fluency test doubled after listening to music on the treadmills.
"Exercise seems to (13) positive changes in the nervous system, and these changes may have a (14) effect on cognitive ability," Emery said.
"Listening to music may (15) cognitive function through different pathways in the brain. The combination of music (16) exercise may stimulate and increase cognitive arousal (17) helping to organize cognitive output."
Emery said he now wanted to (18) people using music of their own choice. "We used the ’Four Seasons’ because of its (19) tempo and positive effects on medical patients in previous (20) ," Emery said. "But given the range of music preferences among patients, it’s especially important to evaluate the influence of other types of music on cognitive outcomes.\
