動詞agreeの使い方

先日、中級クラスの生徒さんから質問をいただいた内容をシェアします。

Q: agreeは、他動詞、自動詞の両方があるが、I agree your proposal. I agree with your proposal. なぜ前置詞が必要なのか。

初級・中級クラスの方と受験生は、まず主語＋agree with + 目的語（賛成する対象物・人）で覚えましょう。自分や身の回りのネタで例文を作り、agree with ~ が自然に出てくるように。

I agree with you.  Tom agreed with Anna's idea.  

1. agreeは、他動詞と取り違えやすい自動詞で、前置詞を落としやすい動詞です。hope、object、apologize、なども同様です。
We all hope for your success.
I object to her going to the party.
I apologise to him for my rudeness.
He quite agreed with me on that point.

2. agreeは自動詞 + 前置詞で、１つの他動詞のような働きをします。look at、look for、look after、consists of、なども同様です。
I quite agree with you.
Neither of my parents agreed to my marriage.
We agreed on an early start.

3. agreeが他動詞として使われる構文には次のようなものがあります。
+ to 不定詞　　We agreed to go to the party.
that節 We agreed that S + V

公式に承認するという意味でagree＋目的語の形も取ります。Congress approved the plan by a large majority.

上級者クラスの生徒さんはこの先も読んでください。
