[语篇解读] 文章讲述了Christopher Cockerell改进了妈妈的缝纫机，使其工作更快，但是妈妈却不想用的故事。该故事告诉我们一个道理；很多人不喜欢新的观点。

1．解析：watched [由前面的时间状语When he was a little boy可知，应用过去时。]

2．解析：knew [文章整体是叙述的过去的事，应该用过去时。]

3．解析：had bought [buy这个动作发生在there was 这个动作之前，即“过去的过去”，故用过去完成时。]

4．解析：shall/will make [句意为：我将要更好地利用它。表示一个将来的动作，应该用将来时。]

5．解析：was not using [句意为：当他的妈妈不用缝纫机的时候，他将玩具蒸汽机固定在了上面。根据语境可知此处应用过去进行时。]

6．解析：was finished [job与finish之间是被动关系，时态用过去时，故填was finished。]

7．解析：would like [根据语境可知，此处表示过去的将来，故过去将来时。]

8．解析：saw [由his mother said可知，应该用过去时。]

9．解析：have been working [由for many years 可知，这个动作从过去持续到现在，有可能延续下去，故用现在完成进行时。]

10．解析：has [此处表示一个客观的事实，用一般现在时。]
