I not only play the guitar，I sing as well（＝I also sing ）.

　　我不但彈吉他，而且還演唱。

　　2、as well 在口語(yǔ)中也可用于句中，作“也好，也行”或“倒不如”解，用來(lái)緩和語(yǔ)氣。如：

　　You may as well go.

　　你去也好。

　　The weather was so bad that we might（just）as well have stayed at home.

　　天氣太壞了，早知道如此，倒不如呆在家里為好。

　　3、as well 可以直接用于just后，用作應答語(yǔ)（可視為It's just as well、的省略），作“幸虧，幸而；無(wú)妨；沒(méi)關(guān)系”解。如：

　　—We were too late to see the film.

　　我們去得太晚了，沒(méi)有看上電影。

　　—Just as well、I hear it isn't very good.

　　不必遺憾，我聽(tīng)說(shuō)電影也不怎么樣。
