also的用法
1.表示“也”, 放在肯定句中,在be動(dòng)詞和情態(tài)動(dòng)詞后,實(shí)意動(dòng)詞前
例Lucy is listening to the radio, Lily is also listening.
露茜正在聽(tīng)收音機(jī),莉莉也在聽(tīng).
2.與其他單詞構(gòu)成短語(yǔ)
如：not only...but also（其中also可以根據(jù)習(xí)慣省去）
注意：只有當(dāng)Not only… but also連接兩個(gè)分句時(shí),才在第一個(gè)分句用倒裝結(jié)構(gòu).如果置于句首的Not only… but also僅連接兩個(gè)并列詞語(yǔ),不可用倒裝結(jié)構(gòu).
