读化肥的污染示意图（图4） ,完成18～19题。

小题1:如图所示施肥过程,可能造成的后果有（ ）

①水体富营养化②酸雨危害③臭氧层破坏

④全球变暖⑤土壤板结

⑥有毒有害物质在作物体内积累

A．①③⑤⑥

B．③④⑤⑥

C．①②④⑤

D．①②③④小题2:由图可以看出,过量施肥可能造成（ )

①土壤污染②白色污染③臭氧层破坏④水体污染⑤农作物污染

A．①②③④⑤

B．①③④⑤

C．①②④⑤

D．①④⑤

答案

小题1:A

小题2:B

小题1:本题考查环境问题的产生。根据图示：图中划分的使用会导致水体富营养化，臭氧层破坏，土壤板结，有毒有害物质在作物体内积累。图示未能反映全球气候变暖和酸雨的产生。所以本题选择A选项。

小题2:本题考查地理图表的判读能力。根据图示：过量施肥可能造成土壤污染，，臭氧层破坏，水体污染，农作物污染。白色污染是塑料垃圾造成的，与过量使用划分无关。所以本题选择B选项。

How to Tell Which Side You Favor


Brain researcher Ned Herrmann tested more than 7,000 people to find out which side of the brain they favored. He found a p relationship between hemisphere (26) and the way subjects made a (27) : left-brain-oriented subjects were more often lawyers, writers, bookkeepers, doctors, tax experts, etc. —jobs (28) with logical, language-related information. Those who favored the right hemisphere (29) out to be poets, politicians, musicians, architects, entrepreneurs, dancers and (30) —top executives. Herrmann’s studies showed that the most successful people in any (31) are those who use both the left and right brains.
One test for hemisphere dominance is to (32) how you turn your head and eyes when (33) questions asked by someone in front of you. Research suggests that if you generally turn to the left, you have a right-brain (34) ; if you turn to the right, (35) are you prefer work that (36) use of logic or language.
Another test for dominance involves directions for (37) a product. A left-hemisphere- oriented person usually follows instructions in a step-by-step (38) —from written sentence to written sentence. Someone with p right-side input will probably (39) the written directions and assemble the pieces by (40) the diagram or picture.
If you think you’re right-brained, (41) this teaser. Read the sentence below carefully and count the number of f’s:
FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE EXPERIENCE OF MANY YEARS.
Did you find all six fs If not, don’t be surprised. Only 15 percent of those who take this test (42) .If you counted less than six—most count three—you probably (43) the f in each "of". Since "of" is pronounced "ov", the verbal left hemisphere took the verbal (44) and overrode the right, "seeing" hemisphere; (45) forcing the wrong conclusion.

A．dominance
