質問: it ではなくthatの理由を教えてください。 it ではなくthatの理由を教えてください。 ted was sad because he was going to change schools. when he told his friends about that, ......... 最後の about thatはabout itだと思いました。「he was going to change schools」これをitに置き換えて about itとするべきではないのでしょうか? 他のと比べてみて何が違うかわかりません。 but they didn't clean the place and went home. masako saw it and became very sad. ここはsaw itな理由はわかります。they didn't clean the place and went homeを当てはめることができますから。同じように上の文もitだと思いました。
回答: > ted was sad because he was going to change schools. when he told his friends about that, ......... この場合、that = he was going to change schools です。 > but they didn't clean the place and went home. masako saw it and became very sad. この場合は it = the place です。 前者は「学校を変る」ということ、後者は「その場所」で、後者は名詞であるという違いがあります。
