信號(hào)詞是定位詞，一般是名詞性質(zhì)的詞和短語，還有數(shù)字年代人名特殊類的，而關(guān)鍵詞每類題型都不一樣了，關(guān)鍵詞一般是動(dòng)詞或者形容詞居多，這個(gè)要講具體的題會(huì)比較明白。信號(hào)詞是定位詞，一般是名詞性質(zhì)的詞和短語，還有數(shù)字年代人名特殊類的，而關(guān)鍵詞每類題型都不一樣了，關(guān)鍵詞一般是動(dòng)詞或者形容詞居多，這個(gè)要講具體的題會(huì)比較明白。
雅思聽力的每段錄音平均為6-7分鐘，大約為700-800單詞，在比較冗長的語段中，說話人肯定會(huì)以重點(diǎn)探討的話題作為語言全面展開的重點(diǎn)，所以對(duì)聽力文稿中信號(hào)詞的定位可以為我們解題起到一種很好的指導(dǎo)，可以讓我們主動(dòng)找答案地聽，而不是被動(dòng)地聽。
1. 轉(zhuǎn)折信號(hào)詞 Contrasting Signals
but, on the contrary, instead, however, in spite of, by contrast, while, despite, unfortunately, although, while, on the other hand, though, whereas, otherwise分析：語意表示轉(zhuǎn)折的信號(hào)詞的出現(xiàn)往往提示說話人即將表達(dá)自己對(duì)某些事情的真實(shí)看法，在此之前的信息被轉(zhuǎn)折之后的信息覆蓋，在轉(zhuǎn)折信號(hào)詞之前的信息往往是語段中的干擾信息。

3. 否定關(guān)系信號(hào)詞 Negative Signals
no, not, none, never, neither, nor, seldom, scarcely, barely, rather than, instead of, hardly, rarely, too…to, few, little, at no time, by no mean分析：在正確信息出現(xiàn)的同時(shí)，往往會(huì)伴隨著干擾信息，所以聽題時(shí)可以借助否定信號(hào)詞來進(jìn)行排除，以確保答案萬無一失。
4. 表示解釋說明 Explanation
It says/shows, the meaning is that, what I mean/mention, that is to say, in other words, Let me put it this way, it means that, another way of saying, the point is that分析：解釋說明的信號(hào)詞重點(diǎn)在于解釋一些聽者可能理解困難的內(nèi)容，或者重復(fù)某重要的信息，當(dāng)信息被反復(fù)解釋或強(qiáng)調(diào)時(shí)，作為正確的答案的可能性會(huì)比較大，所以同學(xué)們要多加注意。
5. 表示例證關(guān)系 Illustration
