英語頻度副詞用法要點(diǎn)
一、頻度副詞的概念與用法
頻度副詞是指表示動(dòng)作發(fā)生的次數(shù)副詞，常見有的never, seldom, sometimes, frequently, often, usually, always 等。頻度副詞通常位于實(shí)義動(dòng)詞之前，動(dòng)詞be、助動(dòng)詞、情態(tài)動(dòng)詞等之后。如：We often get together. 我們常常聚會(huì)。Jane usually goes to work by bike. unt: 2.0">He sometimes goes there on business. 他有時(shí)到那里出差。He can never understand. 他永遠(yuǎn)也不會(huì)明白的。I was never very good at maths. 我的數(shù)學(xué)從來不好。I shall always remember this. 我將永遠(yuǎn)記住這一點(diǎn)。You have often been told not to do that. 多次告誡過你別干那事。注：如果有兩個(gè)助動(dòng)詞，頻度副詞通常放在第一個(gè)助動(dòng)詞后面。如：We have never been invited to one of their parties. 他們聚會(huì)，一次也沒邀請(qǐng)過我們。She must sometimes have wanted to run away. 她有時(shí)候一定想到過要逃走。

二、頻度副詞位于助動(dòng)詞之前兩種情況
1. 為了表示強(qiáng)調(diào)，頻度副詞有時(shí)也可位于動(dòng)詞be、助動(dòng)詞、情態(tài)動(dòng)詞之前；此時(shí)助動(dòng)詞等應(yīng)重讀。如：She alwas late她老是遲到。I never can remember. 我永遠(yuǎn)也記不住。She hardly ever has met him. 她幾乎從來沒有遇見過他。He never should have joined the army. 他根本不應(yīng)當(dāng)參軍。2. 在簡(jiǎn)略答語中，當(dāng)頻度副詞與動(dòng)詞be、助動(dòng)詞或情態(tài)動(dòng)詞位于句末時(shí)，頻度副詞必須前置。如：“Philip is late again.” “Yes, he always is.”“菲利普又遲到了?！薄笆堑?，他總是遲到?！薄癈an you park your car near the shops?” “Yes. I usually can.” “你可以在商店附近停車嗎?”“是的，通?？梢?。”?”“I know I should take exercise, but I never do. 我知道我應(yīng)該進(jìn)行體育鍛煉，但我從來沒這樣做過。

三、頻度副詞位于句首的用法
1. sometimes?？捎糜诰涫?。如：Sometimes she comes late. 有時(shí)她來得晚。Sometimes she didn’t agree with me. 有時(shí)她和我意見不一致。Sometimes we get a lot of rain in August. 有時(shí)在8月份雨水很大。2. often用于句首時(shí)，通常表示強(qiáng)調(diào)，且其前一般有2. oftenquite, very修飾。如：Very often he comes in late. 他常常遲到。Quite often the phone rings when I’m in the bath. 電話經(jīng)常在我洗澡時(shí)響。3. usually有時(shí)也用于句首，其前不用修飾語。如：Usually I get Roman'我平時(shí)起得早。Sometimes he comes by bus, but usually he comes by taxi. 有時(shí)他坐公共汽車來，不過他通常還是打的來。
