英语每日小练习之情态动词并附答案.doc

情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。考点一：can，may，must 等情态动词在陈述句中的用法：1. can 的用法：（1）.表示能力、许可、可能性。 表示能力时一般译为“能、会”， 即有种能力，尤其是生来具备的能力，此时may 和must 均不可代替它She can swim fast, but I cant . 她能游得很快，但我不能。（2）.表示许可，常在口语中。You can use my dictionary. 你可以用我的字典。（3）.表示推测，意为“可能”， 常用于否定句和疑问句中， 此时cant 译为“ 不可能”。Can the news be true? 这个消息会是真的吗？2. could的用法：（1）.can的过去式，意为“ 能、 会”，表示过去的能力。He could write poems when he was 10. 他十岁时就会写诗。（2）. could在疑问句中，表示委婉的语气，此时 could 没有过去式的意思。Could you do me a favour? 你能帮我个忙吗？3. may的用法：（1）.表示请求、许可，比can 正式，May I borrow your bike? 我可以借你的自行车吗？(2) .表示推测，谈论可能性，意为“ 可能， 或许”，一般用于肯定句中。It may rain tomorrow . 明天可能会下雨。(3) .may的过去式为might ，表示推测时。可能性低于may。He is away from school. He might be sick.他离开学校了，可能是他生病了。(4) . 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V May you have a good time. 祝你过得愉快。4. must的用法：(1).must 表示主观看法，意为“必须、一定”。You must stay here until I come back. 在我回来之前你必须呆在这儿。(2) 其否定形式mustnt表示“ 一定不要 ” “千万别” “禁止, 不许”. You mustnt play with fire. 你不许玩火。（3）对must引导的疑问句，肯定回答为must，否定回答为neednt 或 dont have to .Must I finish my homework?我现在必须完成作业吗？No, you neednt.不，你不必。(4)must表示有把握的推测，用于肯定句。The light is on, so he must be at home now.灯亮着，他现在肯定在家。5. need的用法：（1）.need 表示需要、必须，主要用于否定句和疑问句中，其否定形式为neednt，意为“没有必要，不必”。 用need 提问时，肯定回答为 must，否定回答为 neednt或dont have to。 Need I stay here any longer? 我还有必要留在这儿吗？Yes, you must .是的。 No. you neednt /dont have to. 不， 你不必。(2).need 还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语后边多接动词不定式。I need to do it right now. 我需要马上做这件事。6. dare 的用法：dare意为“敢、敢于”, 用法近似于need，有两种词性：（1）dare 作为情态动词，多用于否定句、疑问句或条件句中，无第三人称单数形式，只有一般现在时和一般过去时。 Dare he tell them what he knows? 他敢告诉他们所知道的情况吗？（2）dare 作为实义动词，此时有人称、数及时态的变化。He doesnt dare to break his promise.他不敢食言。7. shall 的用法：shall表示征求对方意见（多用于第一、三人称），Shall we go out for a walk? 我们出去散步好吗？8. should的用法：（1）.should 意为“应该” ，可表示劝告、建议、义务、责任等。We should protect the environment. 我们应该保护环境。（2）Should have done 表示对过去动作的责备、批评。You should have finished your homework. 你应该已经完成作业了。（事实上你没有完成。）9. will 的用法：will表示意愿、意志、打算，可用于多种人称。I will help you if Im free this afternoon.今天下午如果我有空，我就会帮你2、will 与be going to do sth区别：. be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。. be going to 含有“计划，准备”的意思，而 will 则没有这个意思.在有条件从句的主句中，一般不用 be going to, 而多用will,1、_ you pass me a pen?

Many years ago it was hunted for its white fur. Catching or killing Harp Seal is now against law. The Seals spend the summer months moving in large groups. Harp Seals close their noses and ear holes when swimming deep in water, but they have to come out of the water for air from time to time. Their favourite place to rest is on the top of icebergs(冰山). The mother Harp Seal gives babies in February or March and feeds her children for 1418 days. Baby Harp Seals begin to lose their white fur at around six to eight weeks of age. When they grow up, the Harp Seals have brown skin. At birth, Harp Seals weigh 12kg but can weigh up to 130kg as they become grown-ups. Harp Seals eat small fish, shrimps(虾) and krill(磷虾). However they are living in different places. Father Harp Seals can live as long as 29 years while mother Harp Seals usually live for longer than 30 years. Since the Canadian Government passed laws to keep the baby seals from hunters, their numbers have gone up to more than one million. Now every year, thousands of visitors crowd to the pack ice(大片浮冰上) to witness the wonderful picture of newly-born Harp Seals.46.What is the passage mainly about?A.Keeping Harp Seals.
