【解析】短文大意：無(wú)人機(jī)是一種遙控飛機(jī)，近年來(lái)，新技術(shù)使得無(wú)人機(jī)更便宜、更容易買到。無(wú)人機(jī)的使用對(duì)人類有有利的一面，同時(shí)也會(huì)給社會(huì)帶來(lái)很多問題。

【1】句意： 近年來(lái)，新技術(shù)使得無(wú)人機(jī)更便宜、更容易買到。根據(jù)后文時(shí)間短語(yǔ) in recent years可知，本句使用現(xiàn)在完成時(shí)態(tài)，主語(yǔ)是單數(shù)含義，所以助動(dòng)詞為has; made是make的過(guò)去分詞。 故填：has made。

【2】句意：在澳大利亞，無(wú)人機(jī)用于搜索大面積區(qū)域和保護(hù)動(dòng)物。根據(jù)句意可知，主語(yǔ)與謂語(yǔ)存在被動(dòng)關(guān)系，且是一般現(xiàn)在時(shí)態(tài)；所以使用一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)are used。故填：are used。

【3】句意：“你不需要擔(dān)心被鱷魚襲擊，”凱倫·喬伊斯博士說(shuō)。need to do sth. 需要做某事。worry動(dòng)詞，擔(dān)心。 故填：to worry。

【4】句意：越來(lái)越多的生物學(xué)家使用無(wú)人機(jī)，沒有人真正知道它們是否會(huì)對(duì)動(dòng)物造成傷害(通過(guò)恐嚇?biāo)鼈?/span>)。use動(dòng)詞，用，using現(xiàn)在分詞或動(dòng)名詞。根據(jù)句型：There be+sb. doing sth.，意為“有某人在做某事”，所以動(dòng)詞doing形式。故填：using。

【5】句意： 一天，一架無(wú)人駕駛飛機(jī)在美國(guó)的海灘上墜毀，嚇壞了在場(chǎng)的游客。crash動(dòng)詞，墜落；本句描述過(guò)去發(fā)生的事情，所以謂語(yǔ)動(dòng)詞使用過(guò)去式crashed。故填：crashed。

【6】句意：如果無(wú)人機(jī)在我們的社會(huì)中得到廣泛應(yīng)用，就會(huì)出現(xiàn)很多問題。本句是if引導(dǎo)的條件狀語(yǔ)從句，時(shí)態(tài)遵循“主將從現(xiàn)”，所以主句為“will+動(dòng)詞原形”。故填：will be。
