类似问题1：Modern China is experiencing a completely new period___respect for science and creativity has become the guiding principle of society.A.of which B.where C.which D.in which选D.为什么?作定从中的地点状语吗?要是这样,那B呢?[英语科目]
不是做定从中的地点状语.而是做时间状语.注意先行词是period 意思是一段时间,那就应该选D了,如果答案中有when的话,也是对了.
类似问题2：第五题~(>_
类似问题3：-泪奔.一小船从A出发,沿北偏东40°方向航行20海里后到达B,然后又沿北偏西30°方向航行10海里到达C,问此时小船距离A多少海里?（接过精确到1海里）提示：sin40°≈0.6428,cos40°≈0.7660,tan40°≈0.8391[数学科目]
20×cos40+10×cos30≈24
20×sin40-10×sin30≈8
S距离=24²+8²=根号640=8倍根号10≈25
类似问题4：初一几何证明题……在线等～泪奔和同桌想了一下午,郁闷.题： 四边形ABCD中,∠A＝∠C＝90°,BE平分ABC,DF平分ADC,则BE与DF有何位置关系?试说明理由.图：（点开见大图,速度画的,不够标准,见谅~）[数学科目]
四边形内角和=360°,又∠A=∠C=90°
所以∠ABC+∠ADC=360°-90°*2=180°
所以2∠2+2∠4=180°
所以∠2+∠4=90°
又∠DFC+∠4=90°
所以∠2=∠DFC
所以BE‖DF
