The information tells me that the way of education in Canada is quite different from          in China.

one

it

that 

those

考察代词。句意：这条信息告诉我们在加拿大的教育方式和在中国的教育方式很不一样。前后比较的是教育方式，用that 指代the+名词。A. one 是泛指一个，B.it 指的是同一个东西，D. those指代the +名词复数。故选C项。

— Father, you promised!

—Well,____．But it was you who didn't keep your word first．

so was I 

so did I 

so I was 

so I did

考查部分倒装“So + be/情态动词/助动词 + 主语”与表强调的“So + 主语 + be/情态动词/助动词”区别。根据语境“you promised（你许诺过）”和答语“But it was …”可知爸爸回答“我的确许诺过”，且promised是过去时，所以表强调要用助动词did,故选D。句意：——爸爸，你许诺过。——好啦，我的确许诺过。但是是你先没有遵守诺言。

Her father         a writer.

turned

grew

has turned

has become

考查系动词的区别。句意：她的父亲变成了一位作家。Turn，grow，become用作系动词均可表示“变化”，使用时要注意：become主要指一个人暂时性的身心变化或永久性的自然变化，另外还可用于指天气变化和社会的趋势；grow主要表示逐渐变化，强度变化过程；turn后接名词，往往表示意想不到的变化，名词前通常不加冠词。故选D项。

The old rules have to be          because they only applied to the circumstances that existed when they were made a hundred years ago.

developed

established

observed

revised

考查动词的辨析。句意：老的规则需要被修改因为它们只适合一百年制定时的状况。A.develop发展；培养；B.establish建立；C.observe观察；D.revise修改，由because they only applied to 可知它只适用于以前，需要修改。故选D项。

It was last night ________ I saw the comet.

the time

when

that

which

强调句的结构是：It＋be＋强调部分＋that(who)＋主谓句。强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用“who”，其余用that。因此选C。
