【文章內(nèi)容簡介】 a flood，what should we do?萬一發(fā)生洪水，我們該怎么辦？　　解題策略 1．牢記連詞詞義并能熟練運用是解答題目的先決條件；2．牢記固定句式結(jié)構(gòu)，確定從屬連詞；3．根據(jù)主從句的邏輯關系確定狀語從句的連接詞。 如果主從句是因果關系，則要考慮用because，as，since等；如果主從句有時間先后之分，則要考慮用時間狀語從句的連接詞；如果從句為主句的條件，則要考慮用if；如果從句表示讓步，則要考慮用although, though，while等。【典例1】　It is often said that the joy of travelling is not in arriving at your destination__but__in the journey itself． 解析：根據(jù)句意可知，空處前后為選擇關系，not．．．but．．．結(jié)構(gòu)表示“不是……而是……”，連接兩個并列成分，符合句意。故填but?！镜淅?】　 —How long do you think it is __since__ he arrived here?—No more than half a year，I believe．解析： “It is＋時間段＋since sb．did sth．”意為“自從某人做某事到現(xiàn)在有多久了”，為固定句型。故填since?！　∫族e聚焦 一、在寫作中往往缺乏并列句意識，主要存在以下兩個方面的傾向：1．機械排列簡單句I believe I am fit for it． I39。m writing to apply for the position．如果我們把意義相關的這兩個句子用適當?shù)倪B詞連接起來，可得到下面的句子：I believe I am fit for it, so I39。m writing to apply for the position．比較一下，同學們是不是感覺后者要優(yōu)于前者呢？并列連詞的使用可增強句子之間的邏輯性和美感，使句子之間顯得更加緊湊。2．逗號連接兩個簡單句I39。m enthusiastic and easygoing, I39。m easy to get along with and can cooperate well with others．在該句中含有兩個簡單句，中間用逗號起了連接作用，顯然這是不符合英語語法規(guī)則的。我們不妨做如下改動：I39。m enthusiastic and easygoing，so I39。m easy to get along with and can cooperate well with others．二、對于狀語從句，在實際運動中主要存在以下問題：1．從句意識缺乏The Expo is very attractive． We are all eager to pay a visit to it．The Expo is so attractive that we are all eager to pay a visit to it．通過比較不難發(fā)現(xiàn)，后句比前句更加緊湊且邏輯性強，增強了交際效果。2．狀語從句成分殘缺(誤)Please close the doors and windows before leave the classroom．(正)Please close the doors and windows before you leave the classroom．由于受漢語的干擾，第一句中狀語從句中漏掉了主語。3．連接詞誤用(誤)Teachers and parents should respect us no matter we are in or outside school．(正)Teachers and parents should respect us whether we are in or outside school．這兩句盡管從漢語角度來看意思相同，但是從語法角度no matter一般后跟特殊疑問詞，而whether可直接引導狀語從句。(誤)Though he is considered a great writer，but his works are not widely read．(正)Though he is considered a great writer, his works are not widely read．在讓步狀語從句中，though和although不能與but連用。達標檢測 Ⅰ．單句語法填空1．(2020新高考卷)They kept their collection at home until it got too big __or__ until they died, and then it was given to a museum． 解析：考查并列連詞。句意：他們把自己的藏品留在家里，直到收藏變得太大或者自己去世，然后這些藏品被捐給一家博物館。根據(jù)語境可知，前后陳述的是兩者可能性，應使用連詞or“或者”。故填or。2．(2020新課標卷Ⅲ)__When/As__ he asked the villagers on the banks of the river where he could find the legendary (傳奇的) artist, they smiled and pointed down the river． 解析：考查連接詞。句意：當他問河岸上的村民，他在哪里可以找到這位傳奇藝術(shù)家時，他們笑著指著河的下游。本句為時間狀語從句，表示“當……時候”，且從句中動詞asked為短暫性動作動詞，不能用while引導，故應用when或as引導。句首單詞首字母要大寫。故填When/As。3．(2019全國Ⅱ卷) I work not because I have to, __but__ because I want to．解析：考查并列連詞。根據(jù)句意邏輯可知，此處為轉(zhuǎn)折關系，句意：我工作不是因為我不得不做，而是因為我想做。此處用but與前文not 呼應，構(gòu)成“不是……而是……”之意。故填but。4．(四川)It was time for her to have a new baby, __and__ it was also time for the young panda to be independent．解析：句意：是時候再生一個孩子了，熊貓寶寶也到獨立的時候了。It was time for．．．和it was also time for．．．之間是并列關系，故用and連接。5．(新課標全國Ⅰ)But the river wasn39。t changed in a few days __or__ even a few months．解析：a few days和a few months為選擇關系，因此要用or連接。6．(廣東)So Nick called to his son, “Go to the village and buy some salt, but pay
