1. the first thing that my brother and __ did in the morning to go out to see the pony.
1）首先指出句子有错,应该是 the first thing that my brother and I did in the morning is to go out to see the pony.）丢掉了谓语动词 is.
2）句子结构
* 主句：the first thing is to go out to see the pony.
* 定语从句：that my brother and I did in the morning
3）定语从句中的主语是 my brother and I. 既然用作主语,当然应该是主格 I,而不是宾格 me.
2. It is time the dog __ how to behave properly.
1）答案选 c. learned
2）It is time 本意是“到了该做某事的时间”,它有两种用法：如果表达真实语气,用不定式作宾语；如果表示虚拟语气,宾语则用从句.
3）本句的意思是“那只狗是该学会如何做才会得体的时候了”,言外之意是至今都没有学会,所以用过去时 learned 表示对现在的虚拟.
3. Unfortunately, even computers can not completely __ errors.
1）选择 d. eliminate
2）消除错误用 eliminate errors 表示.
3）其他选项： reduce 表示在范围、数量上或程度上减少； decrease 表示在数目、数量或强度方面减少；diminish 是使役动词,表示使宾语减少, 使宾语变小.
