18.今年因?yàn)楦珊,蔬菜價(jià)格增長(zhǎng)了10%.
Because of drought,the prices of vegetables haveincreasedby 10% this year.

分析 increased by

解答 答案:increased by,這里是表示增加了10%,用短語(yǔ)increase by,再者這里是現(xiàn)在完成時(shí)have+過(guò)去分詞,故答案是increased by

點(diǎn)評(píng) 這里是表示增長(zhǎng)了多少用increase by,若是增長(zhǎng)到多少用increase to,這里還要注意時(shí)態(tài)
