(1)The Moto 1100 is a small family car.It has seats for 4 people. →The Moto 1100 is a small family car which has seats for 4 people. (2)The man teaches physics.He is a graduate of Delhi University. →The man who teaches physics is a graduate of Delhi University. 2文を1文にする場合、(2)は”who teaches physics”の部分が関係詞節となりますが、(1)はどこが関係詞節となっているのかが分かりません。 それと、同じ2文を1文に直す時でも、どうして(1)と(2)のつなげ方が違うのでしょうか。 例えば(もっと簡単な例で)、 An object is left in the sun.An object becomes hot. →An object which is left in the sun becomes hot. となりますが、なぜこれは、An object is left in the sun which becomes hot.のようにしてはいけないのでしょうか。逆に、(1)の文は(2)のように、The Moto 1100 which is a small~has seats~.としてはいけないのですか?
