新版牛津英語8A期末語法復(fù)習(xí)資料
don't be careless. 別粗心。 don't let them play with fire. 別讓他們玩火。 (2) let型的否定式有兩種:“don't + let + 賓語 + 動(dòng)詞原形 + 其它成分”和“l(fā)et + 賓語 + not + 動(dòng)詞原形 + 其它成分”。 don't let him go. / let him not go. 別讓他走。 let them not play with fire. 別讓他們玩火。 (3) no開頭,用來表示禁止性的祈使句。 no smoking! 禁止吸煙!no fishing! 禁止釣魚! 3. 祈使句的強(qiáng)調(diào)形式,通常在肯定祈使句式前加上助動(dòng)詞do。 例如:do shut up! 快住口! 4. 祈使句的回答 祈使句的動(dòng)作通常是表示將來發(fā)生的動(dòng)作,所以回答祈使句時(shí),一般用 will或won’t。 在回答具有否定意義的祈使句時(shí),要注意兩點(diǎn): 1) 形式一致(即yes與will保持一致;no與won’t保持一致) 2) 意思相反(即yes是 “不”的意思;no是 “是”的意思)。 在回答時(shí),要注意分析上下文語境中所提供的條件。 如:--- don’t go out, please. it’s raining heavily outside. 請不要出去。外面雨下得很大。 ---- yes, i will. i have to meet my brother at the airport. 不行,我得去機(jī)場接我弟弟。 (二)易錯(cuò)點(diǎn)講解 1、放句首時(shí),要注意don’t后面要用動(dòng)詞原形; 2、當(dāng)人稱后面有標(biāo)點(diǎn)符號時(shí),要注意是用祈使句還是用三單。 如:lucy, don’t be late again. lucy, a 17-year-old girl, is not late again. 3、祈使句與or的搭配, 如:hands up, or we’ll shoot. 【趁熱打鐵】 1. _______ late again, bill! a. don't to be b. don't be c. not be d. be not 2. _______ cross the road until the traffic lights turn green. a. not b. won't c. doesn't d. don't 3. kate, _______ your homework here tomorrow. a. bring b. brings c. to bring d. bringing 4. ________ me the truth, or i'll be angry. a. telling b. to tell c. told d. tell 5 .her doctor said: “________ work so hard” a stop b don’t c can’t d no 6. sindy, ________ to be here at 8 o’clock a is sure b is sure that c will be sure d be sure
