新東方酷學酷玩夏令營介紹在學習青苔動詞時的復習指導。

   新東方酷學酷玩夏令營介紹，在英文中，情態(tài)動詞是使用頻率極高的一類詞。不同的情態(tài)動詞呈現(xiàn)說話者不同的態(tài)度，表達說話者不同的情感，聽話人自然也會因此有不同的心理感受。例如，你的朋友們對你說“we’ll do all we can to help you.”，這里的will 便體現(xiàn)了朋友們幫助你的意愿，關(guān)心你的情感，而你也會因為這份關(guān)愛而快樂。再如，你的室友對你說：“must you make so much noise, tom?”，這里的must 則向你傳遞了室友的不滿情緒，你也會意識到是自己行為不妥，影響了他們�？梢姡�情態(tài)動詞雖不起眼，卻能傳遞豐富的情感。在英語學習中，如何領(lǐng)會小小情態(tài)動詞所蘊含的深情厚意呢？毫無疑問，首先得了解它們的用法。這也正是本文所要解析的問題。下面就結(jié)合近幾年的高考題，分析歸納一下常用的情態(tài)動詞的重要用法，以便同學們能正確運用它們，領(lǐng)會它們傳遞的情感和態(tài)度。

　　a. couldn’t b. shouldn’t 
　　c. can’t d. might not 
　　2． 在口語中，can和 could可以代替may, 表示“許可”，could的語氣比can 更委婉，但答語中不可用could，應(yīng)還原成can。例如：

　　—of course, you can.he said i could use his computer. 
　　3. can和could都可用來表示對現(xiàn)在或過去情況的推測，用于疑問句或否定句，對現(xiàn)在情況的推測，后接一般式或進行式；對過去情況的推測，后接完成式或完成進行式。即： 
　　“can (could ) / can’t (couldn’t) do / be doing / have done / have been doing”。例如： 
　　(1) who can it be at this time of day?
