通り (Tōri or Dōri)

とおり and どおり

「人生は自分の（　　　）とおりにはいかない」
Which is the correct answer for the above blank?
A: 考え
B: 計画
C: 思う

The correct answer is C.

Explanation)
とおり and どおり have the same meaning, but the usages are different.

The basic principle is shown below.

動詞(a verb) + とおり
　名詞(a noun) + どおり

On that case, the question sentence uses とおり, then you should place a verb in the blank parenthesis.
考え and 計画 are nouns, 思う is a verb, so 思う is the correct answer.

考え may seem like 連用形 of the verb 考える, but it can be used as a noun also. In this case, 考え is a noun, the meaning is “What you thought”.

If you try to write A,B or C properly, please use the examples below.

考えた　　とおり
考え　　　どおり

計画した　とおり
計画　　　どおり

思う　　とおり
思い　　どおり
