情态动词：have to，should，can及ought to· 基本用法have tohave to 是一个比较特殊的情态习语，虽然也具有情态动词的功能，但却与其他的情态动词不同。它有人称、数和时态的变化，其否定式和疑问式的构成方式也与情态动词不一样。在使用have to时必须弄清它的真面目，否则容易出错。1. have to 与其他情态动词一样也是后接动词原形，表示外界的强制作用，强调被迫性。含有不情愿的色彩，常译为 “必须，不得不” 。2. have to 可用于多种时态，而且不同时态使用不同的形式：一般现在时中，主语为第三人称单数时用has to ;一般过去时中，用 had to 。have to 还可以用在其他的情态动词之后。例如：I have to do some washing.我必须洗洗衣服。She has to look after her little sister.她不得不照顾她的小妹妹。I had to do my homework last night.昨晚我不得不做作业。3. have to 的否定式和疑问式一般要借用助动词do的适当形式构成。have to 的否定式是don’t have to; has to 的否定式是doesn’t have to; had to 的否定式是didn’t have to 。have to的疑问式同样也借用助动词do的相应形式构成。例如：He doesn’t have to do the homework now.他没有必要现在做作业。—Do I have to go there now?我现在就得去那儿吗?—Yes, you do. /No, you don’t have to.是的，你必须去。/不，你不必。We didn’t have to answer the question yesterday.昨天我们没有必要回答这个问题。can1. 表示能力(如体力和脑力方面)，意为“能;会”等。例如：Can you speak English?你会讲英语吗?Can you play the piano?你会弹钢琴吗?2. 表示请求或允许，多用在口语中，意为“可以;能”等。用于疑问句中用来提出要求，用于否定句表示不允许。例如：Can I help you?我能帮助你吗?You can’t play basketball.你不能玩篮球。Can you...?“请你??好吗?”表示说话人的请求;Can I...?“我可以??吗?”用来征求对方是否允许自己做某事。如在句末加上please一词就显得更有礼貌了。例如：Can you help me, please?请你帮助我好吗?3. 表示可能。例如：He can be at home now.他现在可能在家。The moon can’t always be full.月亮不可能常圆。4. 表示怀疑。在表达此意时，只能用于一般疑问句中，带有感情XX 。例如：Can it be true?那会是真的吗?注意：can的句式变化如下：1. 在变否定句时，直接在我后加上“not”,可缩写成can’t或cannot, 但不能写成cann’t 。例如：He can swim. → He can’t swim.Emma can see the pen on the desk.→ Emma cannot see the pen on the desk.2. 在变一般疑问句时，把我直接移到主语前(原主语的首字母改成小写，第一人称应变为第二人称)即可。例如：I can see an orange on the table. → Can you see an orange on the table?其回答可用Yes, OK或Certainly等作肯定回答;用No或Sorry等作否定回答。例如：—Can you look after my books, please?你能照看一下我的书吗?—OK.可以。ought to1. ought没有人称或时态的变化，后跟带to的不定式。常译作“应该”，“应当”等，和should同义，只是口气稍重一些。其否定式为ought not to (oughtn't to )，疑问式为Ought I /you to??You ought to start at once.你应该立刻出发。Such things ought not to be done.这种事不应该干。--Ought he to go?他应该走了?--Yes, he ought to.是的，应该走了。2. 表可能性Mary ought to be home by now.玛丽这会儿该是到家了。There is a fine sunset. It ought to be a fine day tomorrow.今天有晚霞，明天应该是个好天。It ought to be a fine day tomorrow morning.明天旱晨大概是个好天气。3. 表示没有履行过去的义务时，用“ought to +完成时。You ought to have told me about this earlier.(But you didn't)你本来应该早一点把此事告诉我。(但没有)I ought to have written that letter yesterday.(But I didn't)我本应该昨天写那封信。(但我没写)It ought to have been done long ago.这事早该做完的。2.高二上册英语必修一知识点
