【題目】一位中國小朋友在放暑假前寫了三封信,分別邀請美國、澳大利亞、巴西的三位小朋友到緯度40°、經(jīng)度116°的地方一同度假旅游。他們按照信中所寫的經(jīng)緯度能聚會到一起嗎?可能發(fā)生什么差錯_____________。

【答案】上的地理坐標(biāo)沒有寫明東經(jīng)、西經(jīng)和南緯、北緯。這樣聚會的地點可能有4個,即40°N、116°E;40°N、116°W,40°S、116°E,40°S、116°W。因此他們聚會到一起的可能性很小,可能分散到四個地點

【解析】本題考查用經(jīng)緯網(wǎng)確定方向和任意地點的位置。題干中的地理坐標(biāo)沒有寫明東經(jīng)、西經(jīng)和南緯、北緯,這樣聚會的地點可能有4個,即40°N、116°E;40°N、116°W;40°S、116°E;40°S、116°W。因此他們聚會到一起的可能性很小,可能分散到四個地點。

【題目】閱讀理解
In his lowest days when few people bought his records, Taiwan singer Steve Chou lived alone in Canada and did little. One day, he passed by a local CD store and heard a song that greatly attracted him.
"My heart tells me that music is the thing I truly want to do, not for fame(名譽) or money," Chou said. That's how we luckily have such a music genius, who has since then composed(作曲) lots of hits for the pop music charts (排行榜).
