【解析】

本文包含兩段。第一段：科學(xué)家想了解太空，他們通過望遠(yuǎn)鏡可以發(fā)現(xiàn)很多，想了解更多的話，就要把人類送上月球，但是飛機(jī)無法到達(dá)距離地球184000公里的月球，需要火箭才可以。第二段：我們可以拿一個氣球來看火箭的原理，火箭內(nèi)有加熱氣體，沖出火箭尾部時，火箭就被推上太空了�？傆幸惶�，火箭可以到達(dá)太空中的任何地方。

【1】句意：他們通過望遠(yuǎn)鏡看著它，以這種方式他們發(fā)現(xiàn)了很多。

in this way表示“以這種方式”；根據(jù)“They have looked at it through telescopes (望遠(yuǎn)鏡) and ____1____ they have found out a lot.”可知此處是缺“以這種方式”，故選B。

【2】句意：了解更多情況的唯一方法是把人類送上月球。

find out表示“找到”，根據(jù)the only way to do sth表示“唯一的方法做什么”，所以此處缺動詞原形，結(jié)合所給單詞，故選C。

【3】句意：一架普通的飛機(jī)不能飛到月球上，因?yàn)樵?/span>240公里以上的太空中沒有空氣。

根據(jù)“there is no air above 240 kilometres in space”可知此處是“原因”，所以此處是用“because”，故選D。

【4】句意：但是有些東西在沒有空氣的時候可以飛。

根據(jù)“that can fly when there is no air.”可知此處是定語從句修飾先行詞，此處此處缺名詞，結(jié)合所給選項(xiàng)，故選A。

【5】句意：它不需要翅膀。

根據(jù)“need”接名詞，結(jié)合“It rushed out through the neck of the balloon and this pushed the balloon into the air. ”可知不需要翅膀，故選D。

【6】句意：金屬不能很重，但必須很堅固。

根據(jù)be動詞+形容詞，構(gòu)成系表結(jié)構(gòu)。結(jié)合“be”，可知此處缺形容詞。所以此處是“堅固的”，故選A。

【7】句意：載人火箭已經(jīng)在月球上著陸了。

根據(jù)“have already”可知此處是現(xiàn)在完成時，所以此處缺過去分詞。結(jié)合所給單詞，故選B。

【8】句意：一些沒有載人的火箭被送到了更遠(yuǎn)的另一個世界。

根據(jù)“Rockets with men inside them ”是載人火箭，結(jié)合“Several rockets ____8____ men have been sent to the other world much farther away”可知此處是“沒有載人的火箭”，用“without”，故選E。
