試題分析:這是一篇富有科學(xué)的短文。短文介紹了一種高科技產(chǎn)品----全球定位系統(tǒng)。全球定位系統(tǒng)由三個部分組成-----接收器、衛(wèi)星群、網(wǎng)絡(luò)。它能正確確定你所在的位置,讓你不再迷路。她已經(jīng)廣泛應(yīng)用于汽車、飛機(jī)、輪船等交通工具,將來它還會像手機(jī)一樣普及在日常生活中。
小題1:細(xì)節(jié)理解題。短文最后說到:Everyone will have one and you will never be lost again.每個人都會有一個全球定位系統(tǒng),這樣你再也不會迷路了。故選A。
小題2:細(xì)節(jié)理解題。短文第二段說:There are three parts to GPS.全球定位系統(tǒng)有三個部分。所以應(yīng)該選A。
小題3:細(xì)節(jié)理解題。這個題目要結(jié)合上文理解,短文說:The third part of the system is a network of ground stations all over the world. They control (控制) the satellites and make sure they are working well.第三部分是全世界的地面基站網(wǎng)絡(luò),他們控制著衛(wèi)星確保衛(wèi)星正常運(yùn)轉(zhuǎn)。所以這里的they是指地面基站網(wǎng)絡(luò)。故選D。
小題4:細(xì)節(jié)理解題。從短文最后一段可以看出全球定位系統(tǒng)將會廣泛應(yīng)用于日常生活中。Some people think that in the future the GPS will be as common as the mobile.人們認(rèn)為將來全球定位系統(tǒng)會像手機(jī)一樣普遍。Perhaps they will become like watches.也許他們會像手表。所以選D。
