Having meals at the restaurant is much more expensive than eating at home.謝謝你，你的回答太好了。還想再追問(wèn)一下，如果是確切的3倍，又怎么說(shuō)呢？是Having meals at the restaurant is three times than eating at home這樣的么？感覺(jué)不太對(duì)不是的..is three times than 沒(méi)有突出是價(jià)值還是什么..Having meals at the restaurant is three times as expensive as eating at home.或者 increase threefold或者increase by 300％都可以表示增長(zhǎng)三倍的意思對(duì)的，太感謝了！就是后面兩個(gè)的話，整個(gè)句子是Having meals increases three fold than eating at home? Having meals increases by 300% than eating at home?是這樣子么？不好意思，又麻煩您了，我的這個(gè)比較級(jí)總是反應(yīng)不過(guò)來(lái)The cost for having meals at the restaurant increases threefold than that at home? The cost for having meals at the restaurant is increases by 300% than that at home?這兩個(gè)是說(shuō)增長(zhǎng)了三倍,要提出是價(jià)格增長(zhǎng)了三倍
