        情態(tài)動詞是歷屆中考的重、難點(diǎn)之一。 同學(xué)們在復(fù)習(xí)備考時(shí)要注意以下三點(diǎn): 1. 從句式角度進(jìn)行分類復(fù)習(xí)。2. 利用對比法進(jìn)行復(fù)習(xí)。3. 注意近年來中考情態(tài)動詞的新考點(diǎn)的復(fù)習(xí)和運(yùn)用。現(xiàn)就歷屆中考的幾個(gè)重點(diǎn)、難點(diǎn)作一講述。

        [考點(diǎn)一] can / could ; may / might; must 表推測的用法

        [考點(diǎn)點(diǎn)撥] (1)can / could 表示推測的用法時(shí),意為"可能",常用于疑問句、否定句,could表示推測時(shí),不表示時(shí)態(tài),其程度不如can。

        (2)may / might 表推測時(shí),用在肯定句中,意為"可能; 也許",might此時(shí)也不表示時(shí)態(tài),其推測程度弱于may。

        (3)must 表示很有把握的"一定",用于肯定句。

        [考題回放] 1. Tom ___ be in Shanghai. Because I saw him just now. (2003 上海)

        A. shouldn't B. mustn't C. may not D. can't (答案為D)

        2. Return home quickly. Your parents ______ be worrying about you now. (2004 重慶)

        A. can B. would C. must D. could

        (答案為C)

        [考點(diǎn)二] can 與be able to 的區(qū)別與運(yùn)用

        [考點(diǎn)點(diǎn)撥] can 可以表示能力及可能性,它沒有人稱和數(shù)的變化; be able to 除了表示能力外,還可以表示"經(jīng)過一番周折干成某事", 它有人稱和數(shù)的變化。can只有現(xiàn)在式和過去式,而be able to可用于各種時(shí)態(tài)。

        [考題回放] 3. He was a clever student. So he ______work out the problem at last. (2002安徽)

        A. could B. would C. might D. was able to (答案為D)

        [考點(diǎn)三] used to與would的區(qū)別及運(yùn)用

        [考點(diǎn)點(diǎn)撥] 二者均可表示"過去常常"之意, 但would 常表示過去的習(xí)慣動作,而不表示過去的狀態(tài), 且沒有與現(xiàn)在對比的含義。used to 表示"過去常常......(而現(xiàn)在已不如此)",它既可以表示動作,也可以表示狀態(tài),強(qiáng)調(diào)過去與現(xiàn)在的對比。

        [考題回放] 4. He said there ______ be a hospital here. (2003黑龍江)

        A. would B. used to C. must D. can (答案為B)
