1. 结合语境可知此处用一般过去时，decide的过去式为decided；2. 由并列动词came和began可知此处用一般过去时，lay的过去式为laid；3. 此处修饰整个句子，需用副词，hopeful的副词形式为Hopefully；4. Two years ago是一般过去时的标志，ride的过去式为rode；5. tell lies是固定短语，意为“说谎”，故填lies。
四、按要求完成句子，每空一词。

答案
1. Did; turn 2. had; bread 3. How; was 4. How; does; go 5. When; did
解析
1. 原句为一般过去时，变一般疑问句需借助助动词Did，后面动词还原为原形turn；2. 用yesterday改写时，时态变为一般过去时，has的过去式是had；3. 对表示状况的not bad提问，用How，原句be动词was提前；4. 对交通方式on foot提问用How，一般现在时主语Tom是第三人称单数，疑问句借助助动词does，后面动词还原为原形go；5. 对时间last year提问用When，原句为一般过去时，借助助动词did。
