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

one

it

that 

those

考察代詞。句意：這條信息告訴我們在加拿大的教育方式和在中國的教育方式很不一樣。前后比較的是教育方式，用that 指代the+名詞。A. one 是泛指一個(gè)，B.it 指的是同一個(gè)東西，D. those指代the +名詞復(fù)數(shù)。故選C項(xiàng)。

They elected him          captain of the team for         second time.

the; a

a; the

a; a

/; a

考查冠詞的用法。句意：他們再次選他當(dāng)隊(duì)長。職位，官銜前面不加冠詞，a second time表示“又一次，再次”；the second time表示第二次（順序）。故選D項(xiàng)。

—Have you watered the flowers?

I am

I’m going

I’m just going to

I will go

句意為：——你澆花了嗎？——沒有，不過我正打算澆。I’m just going to.相當(dāng)于I’m just going to water the flowers。故選C。

There                   in the world              China is a great country with a long history and rich culture.

are no doubt; that 

are not doubts; if

is no doubt; that

is not doubt; if

考查固定句型和同位語從句。句意：毫無疑問，中國是世界上有著悠久歷史，豐富文化的一個(gè)大國。分析句子可知，這個(gè)句型為 there is no doubt that 引導(dǎo)，表示“毫無疑問......”.本句為that that 引導(dǎo)的同位語從句，句意和句子結(jié)構(gòu)完整。故選C項(xiàng)。
