water closet,is old⁃fashioned English.It sounds dirty to me,”says Charlie Shifflet,a young man from the US.The old sign will become“Gents/Men”and“Ladies/Women”.“I see lots of poor English in everyday life,not only on signs,”he says.“I know what they mean.But they are Chinglish(中国式英语),not real English.For example,when someone says to me‘My hometown is Henan Province.’I know he should say,‘My hometown is in Henan Province.’‘Hometown’is a smaller place in a province.”The common mistakes he picked up include“Not Entry”,which should be“No Entry”.“Direction of Airport”should be changed into“To the Airport”.And it is“room rate”,not“room price”.And remember to “Keep off the grass”,rather than“Care of the green”.(E9301003)26.What does the writer think of the use of“WC”?A.He doesn't think it

2010年第20号超强台风“卢碧”已于10月20日早晨减弱为强台风，20日5时“卢碧”的中心位于北纬20度、东经131度。

读图回答2、3题。

2.20日5时，台风中心位于图中的（）A.A点B.B点C.C点D.D点3.若某轮船航行到图中B地，此时轮船位于台风中心的（）A.东北方B.西南方C.东南方D.西北方【解析】2选A，3选B。

结合图中各点的经纬度位置判断,A点与题干台风中心最为符合；从纬度看B点位于A点的南方，从经度看B点位于A点的西方。

（2010·湖南常德）下图H、F是圆圈上的两个点，O是圆心。

据此回答4、5题。

4、假如圆圈表示一个经线圈，站在H点的科考专家的前后左右都是北方，则F点的纬度为（）A.90°NB.60°NC.90°SD.0°5、假如圆圈表示一条纬线，H的经度为20°E，则F地（）A.其经度为160°EB.位于海洋上C.位于南半球上D.位于西半球【解析】4选A，5选D。

H点在南极点上，前后左右都是北方，所以H点的纬度是90°S，与之相对的F 点是北极点,纬度应是90°N。

若H点的经度为20°E，因为相对的两条经线度数和为180°,且分别属东经度和西经度，所以F地位于160°W经线上,由于纬度不确定，因此无法确定F地位于海洋还是陆地,也无法确定F地位于南北半球中的哪个半球，但160°W经线位于西半球,因此F地位于西半球。

我国某优秀跳水运动员在跳台上腾空而起的英姿，运动
员从离水面10 m高的平台上向上跃起，举起双臂直体
离开台面，此时其重心位于从手到脚全长的中点，跃起
