背景資訊(UFO的含義和“飛碟”的由來(lái))UFO是英文(UnidentifiedFlyingObject)的縮寫,意為不明飛行物.它的含義,從廣義講是天空中一切不明原因和無(wú)法解釋的飛行物,而狹義講指外星人的飛行器.人們常常提到的UFO是廣義上的飛碟,但外星人的飛行器至今也未收集到.一般UFO具有一些無(wú)法解釋的特性,如具有超出最快火箭的高速度,或可在高速運(yùn)動(dòng)時(shí)瞬間停止懸空,或停在空中有瞬間高速飛離的本領(lǐng),能直角轉(zhuǎn)彎,自身旋轉(zhuǎn),無(wú)聲無(wú)息,瞬間消失等特性.為什么會(huì)有這些特性還有待研究.“飛碟”名稱的由來(lái)1947年6月24日,肯尼思架著自己運(yùn)貨的飛機(jī)在美國(guó)華盛頓州卡斯卡德山脈上空飛行.下午他飛抵雷尼爾山附近,架著飛機(jī)兜了一會(huì)圈子,尋找一架曾在這里失蹤的飛機(jī).他突然發(fā)現(xiàn)左側(cè)稍遠(yuǎn)地面上有幾個(gè)發(fā)光的物體.九個(gè)發(fā)光物體排成一行前后高低,每個(gè)呈發(fā)光圓形,有飛機(jī)大小,這一行在峰巒間穿行,有時(shí)還繞過(guò)一個(gè)山頭.每小時(shí)約飛2700公里.著陸后記者問(wèn)他,這些物體如何飛行.他并未說(shuō)飛行物是碟子,而是說(shuō)物體飛行像貼著水面拋出的碟子.可是,第二天的美國(guó)報(bào)紙報(bào)道說(shuō),他看到了“飛碟”.Teachinggoals:1.Words:barbershop,well,bathroom,accident,earth,silence,playground,around,strange,kitchen,modern,follow,shirt.2.when,while引導(dǎo)的時(shí)間狀語(yǔ)從句。3.學(xué)習(xí)過(guò)去進(jìn)行時(shí)態(tài)。4.利用知識(shí)談?wù)撨^(guò)去發(fā)生的事情。5.復(fù)習(xí)過(guò)去式，學(xué)會(huì)講故事。6.
