【分析】做语法填空时，需先通读全文把握语境，再结合句子结构、语法规则、固定搭配等逐一分析每个空：第1空前后为转折关系，需用转折连词；第2空主语是单数概念，谓语动词用单数；第3空all后接可数名词复数；第4空是固定短语搭配；第5空是固定句型的非谓语形式；第6空需用副词表顺序；第7空是固定动词搭配；第8空需遵循条件状语从句的时态规则；第9空修饰名词需用形容词性物主代词；第10空修饰动词需用副词。
【解析】1. 考查转折连词，前句提到太空站生活有趣，后句指出存在诸多问题，为转折关系，故填but；2. 考查主谓一致，主语为“one of +复数名词”，表单数概念，时态为一般现在时，be动词用is；3. 考查名词复数，all后接可数名词复数，meal的复数形式为meals；4. 考查固定搭配，for a long time是固定短语，意为“很长时间”，故填a；5. 考查非谓语动词，固定句型It takes sb +时间+to do sth，故填to prepare；6. 考查副词，此处表示“首先”，修饰动词短语fix...，用副词first；7. 考查固定搭配，tie sth to sth是固定搭配，意为“把某物绑在某物上”，故填to；8. 考查时态，if引导的条件状语从句遵循“主将从现”原则，主句用一般将来时，故填will get；9. 考查代词，修饰名词food需用形容词性物主代词，故填their；10. 考查副词，修饰动词float需用副词，easy的副词形式为easily。
【答案】1. but 2. is 3. meals 4. a 5. to prepare 6. first 7. to 8. will get 9. their 10. easily
