2017专八改错练习（6）

　　Ancient man attempted to change the weather by using magic. While experience taught him this was impossible, __1__ he tried to forecast weather conditions. Even earlier in __2__ 1000 B.C.there were weather seers in Babylon----and priests clever enough to denounce as frauds those predicted __3__ the weather a year in the advance. Some forecasters used __4__ methods that seemed to take no connection with the actual __5__ factors controlled the weather. Chickens and other animals __6__ were sacrificed and their intestines poked to find signs indicating rain and drought. Somewhat more scientific predictions were __7__ based on vegetation:"Onion’s skin very thin ,mild weather coming in. Onion’s skin thick and tough, coming weather is cold and rough." Insects and animals were also __8__ favorite weather clues: "Before the glowworm lights his __9__ lamp , then the air is always damp ." "If spiders their forsake cobwebs, the weather will for certain break ." "If frogs remained in pools , the weather will be fine . If they were seen on rocks, __10__ rain and cold were due." It’s difficult to say whether this rhyme should be taken seriously : " Hark , I hear the asses bray . Me thinks we’ll have some rain today ."

　　答案和解析:

　　1. While—When或After.本句的this指代的是to change the weather by using magic. when/after 引导时间状语

　　3. those之后加who.who引导定语从句

　　4. 删除advance前的the.in advance为习语

　　5. take—have.have connection with 为习语

　　6. controlled—controlling或在controlled前加that/which.controlling the weather 或that/which controlled the weather做定语修饰the actual factors

　　7. and—or.rain和draught只能是二者之一

　　8. 删除is.与上文平衡，均为省略句

　　9. before—when/if.条件句

　　10. will—would.if引导的是条件句用的是remained一般过去时
