初三 情態(tài)動(dòng)詞 語法講解及習(xí)題 沖刺

1、初三英語講義（3月16號(hào)）情態(tài)動(dòng)詞考點(diǎn)解讀：情態(tài)動(dòng)詞在中考單項(xiàng)選擇中一般會(huì)占一分的比例，但是在完形填空，閱讀理解和作文中會(huì)經(jīng)常遇到，所以學(xué)習(xí)和掌握情態(tài)動(dòng)詞非常重要。 每日一句：. 千里之行,始于足下. The longest journey begins with the first step.初中所有的情態(tài)動(dòng)詞：May/might can/could must/have to shall/should need, dare, ought to, had better一 含義情態(tài)動(dòng)詞是表示說話人的語氣。二 特征1. 情態(tài)動(dòng)詞有一定的詞義，但不能單獨(dú)做謂語，要和系動(dòng)詞和行為動(dòng)詞共同構(gòu)成謂語。2.
