Keys to A：1．a→an 2．has→had 3．day→days 4．√ 5．去掉so 6．good→bad或在good前加not 7．在caught前加which／that 8．That→It 9．去掉to 10．came→went
解析：2．这里的now并非指现在，而是故事中的“当时”，如：He opened the door．Now the noise was very loud．文中说连续打鱼84天，在这之前应用过去完成时，故 has→had。5．前面after forty days without a fish是短语而非从句，故去掉so。6．这是一道文意题，老人一直没抓到鱼，小孩父母认为他交坏运而非交好运。故good→bad或在good前加not。8．made的主语应为后面的不定式，故用It做形式主语而不能用That。10．小孩前往帮忙而非过来帮忙。故came→went。
Keys to B：1．is→was 2．a前加into 3．√ 4．he前加when或将that→when 5．to→into 6．raised→rose 7．Exciting→Excited 8．shouted→shouting 9．去掉was 10．wildly→wild
解析：1．根据全文时态应用过去时，故is→ was。4．that引导noticed的宾语从句，而he got．．．是该从句的时间状语从句，故应加when或将that改为when。8．shouted是谓语动词，这儿应用shouting作状语。
