【文章內(nèi)容簡(jiǎn)介】 n’t very well these days and has to stay at home. We have to go and help him. You don’t have to tell me this. Do you have to do everything. She doesn’t have to e this afternoon. 注意： have to 在口語(yǔ)中也可用 have got to 代替，意思與 have to 一樣，也表示 客觀需要或義務(wù)。 辨析： have to 與 must 兩者都有“必須”的意思，它們的基本區(qū)別是： have to 表示客觀的需要，而 must則表示主觀的需要，例如： We have to clean our classroom every day. We must clean our classroom every day. must 也表示“義務(wù)”，這種義務(wù)來(lái)自講話人，表示講話人的要求，當(dāng)我們表示這種要求不是來(lái)自講話者，而是來(lái)自別人或其他外界因素。（如各種規(guī)章制度）時(shí)，常常用 have to。例如： You have to do your exercises in class. K] I really must stop smoking. 2. raise v. 舉起 例如： If you have any questions, you can raise your hands first. Please raise your voice, I can’t hear you. 同義詞 lift 辨析： raise， rise 和 lift raise 是及物動(dòng)詞，后面可接賓語(yǔ)，多指將物體垂直向高處或?qū)⑵鋸妮^低的平面移至較高的平面。 rise 是不及物動(dòng)詞，不可以
