【分析】
连词成句需先根据标点判断句子类型（陈述句/疑问句），再梳理句子成分（主语、谓语、宾语等），结合固定搭配和句型结构组合单词，注意大小写和标点。1题标点为句号，是陈述句，先找主语They、谓语use、宾语a spaceship，用固定搭配use sth to do sth连接fly there；2题标点为问号，是there be句型的一般疑问句，需将be动词Is提前；3题标点为句号，是陈述句，主语I，副词really修饰want，结合固定搭配want to do sth；4题标点为问号，是特殊疑问句，疑问词What开头，助动词do提前；5题标点为句号，是陈述句，结合固定搭配a lot of work即可。
