Watch the vide and talk abut it.
Frm the vide, we can knw what we are ging t learn tday?情態(tài)動(dòng)詞（Mdal verbs）是本身有一定的詞義，表示語氣的單詞。但是不能獨(dú)立作謂語，只能和動(dòng)詞原形一起構(gòu)成謂語。情態(tài)動(dòng)詞用在行為動(dòng)詞前，表示說話人對(duì)這一動(dòng)作或狀態(tài)的看法或主觀設(shè)想。 情態(tài)動(dòng)詞雖然數(shù)量不多，但用途廣泛，主要有下列： can (culd), may (might), must, need, ught t, dare (dared), shall (shuld), will (wuld)
