23、詞不重讀。(1)名詞、動詞、數(shù)詞、形容詞、副詞是實詞，一般要重讀。從句子入手寫好文章文章是由句子構(gòu)成的，要寫好文章，首先要寫好句子。句子至少應具備下列幾點才能有效地表情達意正確、一致、明晰、連貫、有力。然而考生受其英語基礎和母語的影響，總是會犯這樣那樣的錯誤?，F(xiàn)將句子寫作中應該注意的事項和可能出現(xiàn)的錯誤介紹如下：1內(nèi)容要明晰句子表達的內(nèi)容必須清楚，不能造成歧義。如：模糊：He told his father that he was wrong.他告訴父親是他錯了。(從句中的 he 指代不清)清楚：He told his father that his father was wrong.他告訴父

24、親是父親錯了。清楚：He told his father that he himself was wrong.他告訴父親是他自己錯了。2句子結(jié)構(gòu)要對等句子中的并列成分之間在結(jié)構(gòu)上應該對等。如：誤：You may either ask your brother or your sister.正：You may ask either your brother or your sister.你可以問一下你的哥哥或姐姐。3句子要合乎邏輯(1)句子中的名詞和代詞的數(shù)前后應保持一致。如：誤：Being a student, we all wish to learn English well.正：As st

25、udents, we all wish to learn English well.作為學生，我們都希望能學好英語。(2)句子中的語氣、語態(tài)和句法結(jié)構(gòu)應一致。如：誤 ： Thinking of his son, who died a week ago, tears camedown from the old mans face.正 ： Thinking of his son, who died a week ago, the old manburst into tears.一想到一周前去世的兒子，老人就潸然淚下。4避免斷句句子結(jié)構(gòu)要完整，避免寫成一個短語或從句。如：斷句：How we shou

26、ld write.我們應該怎樣寫。修訂句：That is how we should write.這就是我們應該怎樣寫。修訂句：How should we write？我們應該怎樣寫呢？5避免碎句一個連貫的信息不宜用若干短句表達，改正方法主要有并列法、從屬法，也可將那些不太重要的句子縮成短語。如：碎句：He is our English teacher.His name is Wang Bin.He hastaught us for two years.他是我們的英語老師。他的名字叫王濱。他教了我們兩年。連 貫 ：Wang Bin, our English teacher, has taugh

27、t us for twoyears.王濱，我們的英語老師，已經(jīng)教了我們兩年。連貫：Wang Bin has taught us English for two years.王濱已經(jīng)教了我們兩年英語。6避免混雜句混雜句是指句子與句子之間缺少必要的標點和連詞，也指誤用連詞，通常是千篇一律地使用 and, but, so 這樣幾個并列連詞。如：混雜句：You enter the city and you will see the tower.修訂句：If you enter the city, you will see the tower.如果你進了城，你就會看到那座塔。7避免累贅所謂累贅是指句中使

28、用了不必要的詞。如：累贅：The student put a letter that came from Fujian on mydesk.簡潔：The student put a letter from Fujian on my desk.學生把一封來自福建的信放在我桌上。與累贅相反的情況是缺詞。如：缺詞：Our country is larger than any country in Asia.完整：Our country is larger than any other country in Asia.我們國家比亞洲其他任何國家都大。8避免中式英語中式英語指句子表達不符合英語句型或英語習慣，或是書寫時只根據(jù)漢語意思選擇詞匯，而忽視該詞在英語中的特定含義和用法。如：誤：Tomorrow will be fine.正：It will be fine tomorrow.明天天晴。
