【分析】
做连词成句题时，首先第一步先观察句末给出的标点，判断句子是陈述句还是疑问句；第二步优先挑选首字母大写的单词作为句首词，再梳理句子的主谓宾主干结构，最后把剩余的时间、地点等修饰状语放到对应合适的位置，组合完成后通读整句，检查语法是否通顺、所有给出的单词都没有遗漏。
【解析】
① 本句是祈使句+时间状语从句的结构：大写的Look是祈使句的句首，before作为连词引导后面的时间状语从句，从句主语是you，谓语是cross，宾语是the street，组合后得到句子：Look before you cross the street.
② 本句是含情态动词的否定陈述句：大写的We是句子主语，后接情态动词否定形式shouldn't，之后是固定搭配play computer games，最后接时间状语for too long，组合后得到句子：We shouldn't play computer games for too long.
③ 本句是现在进行时的特殊疑问句：标点为问号，大写的特殊疑问词What放句首，特殊疑问句结构为"特殊疑问词+be动词+主语+现在分词+状语"，be动词是are，主语是they，现在分词是doing，地点状语是in the garden，组合后得到句子：What are they doing in the garden?
④ 本句是there be句型的一般疑问句：标点为问号，大写的be动词Are放句首，遵循"Are there + 名词 + 地点状语"的结构，名词是any fish，地点状语是in the river，组合后得到句子：Are there any fish in the river?
⑤ 本句是一般过去时的否定陈述句：大写的I是句子主语，后接助动词否定形式didn't，之后是固定动作搭配go ice fishing，组合后得到句子：I didn't go ice fishing.
⑥ 本句是一般过去时的陈述句：大写的We是句子主语，谓语是过去式climbed，宾语是the hill，时间状语last Sunday放句末，组合后得到句子：We climbed the hill last Sunday.
【答案】
① Look before you cross the street.
② We shouldn't play computer games for too long.
③ What are they doing in the garden?
④ Are there any fish in the river?
⑤ I didn't go ice fishing.
⑥ We climbed the hill last Sunday.
