3、look for the boy, however. 【自我歸納】 1. 二者都意為“_”。2. _是并列連詞，連接兩個(gè)并列分句，兩分句間可用逗號(hào)也可不用，兩句在總的意義上構(gòu)成了對(duì)比關(guān)系。3. _不能直接連接兩個(gè)分句，必須另起新句，并常用逗號(hào)與句子隔開(kāi)。【名師指津】 1. (1)從語(yǔ)意上看，but所表示的是非常明顯的對(duì)比關(guān)系，轉(zhuǎn)折意味比however強(qiáng)。(2)從語(yǔ)序上看，but總是位于所引出的分句之首， but之后一般不使用逗號(hào)。2. however作副詞用時(shí)，表示“然而；但是”，可以位于句首、句中和句末。(1)位于句中時(shí)，其前后都要用逗號(hào)隔開(kāi)；(2)位于句首時(shí)，要用逗號(hào)與句子其他部分隔開(kāi)；(

5、while意為“_”，用作并列連詞，表示前后的對(duì)比關(guān)系，所引導(dǎo)的句子不能置于_。2. while也可用作從屬連詞，引導(dǎo)讓步狀語(yǔ)從句，意為“_”，可與although換用，所引導(dǎo)的句子多置于_。3. although為從屬連詞，引導(dǎo)讓步狀語(yǔ)從句，意為“_”，相當(dāng)于though, 所引導(dǎo)的句子通常置于_。【名師指津】1. while引導(dǎo)的讓步狀語(yǔ)從句在意義上一般與主句的對(duì)比不太強(qiáng)烈，即主句與從句只是部分不一致；而although引導(dǎo)讓步狀語(yǔ)從句時(shí)，所引導(dǎo)的從句往往使主句內(nèi)容含有使人感到意外或料想不到之意。2. although/though不能與but同時(shí)出現(xiàn)在同一個(gè)句子中，但可以與still,

6、yet連用。【想一想】 while除了引導(dǎo)讓步狀語(yǔ)從句和并列句外，還有沒(méi)有其他用法？試舉例。 【知識(shí)鏈接】 1)while可引導(dǎo)時(shí)間狀語(yǔ)從句，表示“當(dāng)時(shí)候，趁著時(shí)”，但要注意，while從句的側(cè)重點(diǎn)在于描述動(dòng)作正在發(fā)生的狀態(tài)，即當(dāng)while事件正在發(fā)生的時(shí)候，另一件事如何。You cant do your homework while youre watching TV. 你不能一邊看電視一邊做家庭作業(yè)。2)while表示條件，意為“只要”。There will be life while there is water and air. 只要有水和空氣就會(huì)有生命。【活學(xué)活用】1. 選詞填空(b
