(人教版)高中英语必修3同步讲练：Unit 1 Grammar (含答案)
GRAMMAR情态动词（一）【归纳】一、can和could★表示能力。
can表示现在的能力，could表示过去具有某种能力。
如：My brother can speak four foreign languages.Sophia could read when she was four years old.注意：can表示“能够”时与be able to同义，但can只有过去式could，而be able to可用于各种时态。
另外，could表示某人过去有某种能力，而was / were able to表示某人通过努力、克服困难做成某事，相当于managed to。
如：She will not be able to visit the hospital tomorrow.Mike was an excellent tennis player when he was young. He could beat anybody.The fire spread through the building very quickly, but fortunately everybody was able to escape.★表示许可。
could比can表示的说话语气更委婉。
如：You can have a piece of cake after you’ve eaten your vegetables!Could I have a drink of water, please?★表示可能性。
此时could不是can的过去式，它表示推测的可能性比can小。
如：Can he still be alive after all this time?If you’re not careful, you could get into even worse trouble.二、may和might★表示许可或征求对方许可。
如：You may / might use my bicycle so long as you return it before 12:00.I can’t eat; may / might I have a little brandy?★表示可能性。
might比may语气更不确定，表示的可能性更小。
如：He may / might get here in time, but I can’t be sure.三、will和would★表示意愿。
will表示现在的意愿，有时可用于条件句中，would表示过去的意愿（would 如表示现在的意愿，语气较委婉）。
如：I will help her if she asks us to.Ask, if you will, who the owner is.My friend asked if I would go with him.★表示征求意见或提出请求。
will与would均可用于主语是第二人称的疑问句中，表示征求意见或提出请求，此时would并不表示过去，而表示委婉语气。
如：—I’m cold. Will / Would you shut the window, please?—Certainly.★表示习惯和倾向性。
will表示现在的习惯，would表示过去的习惯。
如：She will listen to records, alone in her room, for hours.When Ann was a child, she would often ask some strange questions.四、shall和should★shall在疑问句中用于征求对方意见，主要用于第一人称，也可用于第三人称，意为“要不要，……好吗”。
如：Shall we go out and have a walk after dinner?Shall Tom go there with me tomorrow?shall还可用于主语是第二、三人称的陈述句中，表示决心、允诺、警告、命令、威胁、规定或义务等。
如：Tell her that she shall have the bike tomorrow.You shall be punished if you break the rule.★should表示义务或责任、建议或劝告、推断等。
如：We should take good care of our children.You shouldn’t leave a baby alone in the house.I w onder what’s happened to Annie. She should be here by now.should还可以表示惊讶、失望、遗憾等情感，此时意为“竟会”。
如：It’s strange that Jane should be late. She’s usually on time.I’m sorry that you should think so badly of me.五、must和can’t★must可表示“必须做某事”，还可表推测。
must表示推测时用于肯定句中，意为“肯定，一定”。
如：I must go to the bank to get some money.—Where is Tran Nguyen from?—I know that’s a Vietnamese name. He must be from Vietnam.★can’t可表否定的推测和判断，意为“不可能”。
如：You’ve just had lunch. You can’t be hungry.【即学即练】I.1. With my help Peter ________ speak Chinese fluently now, but he ________ not when he came here last year.2. —May I take the book home?—No, you ________.3.

2020届高考英语(人教版)必修四课堂要点精析讲义Unit 1 Section Ⅲ Grammar—主谓一致含答案
Section_ⅢGrammar—_主谓一致语法图解探究发现①Following Jane’s way of studying chimps, our group are all going to visit them in the forest.②Watching a family of chimps wake up is our first activity of the day.③Everybody sits and waits in the shade of the trees while the family begins to wake up and move off.④Jane warns us that our group is going to be very tired and dirty by the afternoon and she is right.⑤Ten hours has passed since I came here.[我的发现](1)句①中group强调成员，故其后谓语动词用复数形式；句③中的family和句④中的group强调整体，故其后谓语动词用单数形式。
(2)句②中的主语为动名词短语，故其谓语动词使用第三人称单数形式。
(3)表示时间、距离、金额、度量衡等名词作主语时，常表示一个整体概念，谓语动词用单数形式，如句⑤。
谓语动词与主语必须在人称和数上保持一致，这叫主谓一致。
主谓一致的应用主要有以下几种情况：一、名词作主语主语谓语动词可数名词单数或不可数名词单数可数名词复数复数只表示复数意义的集体名词people, police, cattle等复数family, class, group, team类集体名词强调整体单数强调成员复数只作不可数名词用的集体名词clothing, equipment,furniture, jewellery等单数单复数同形的名词means, sheep, works, deer, fish等根据其表达的单复数意义而定The public was kept in the dark about the matter.关于这件事情公众被蒙在鼓里。

For some people, the answer is provided by the Guide Horse Foundation.Janet and Don Burleson founded the organization in 1999.They began training miniature horses to help guide blind people.Miniature horses look just like regular horses, only much smaller.They are generally less than 34 inches tall.Cuddles was the foundation's first guide horse in full service.She became 45yearold Dan Shaw's helper.Shaw has an eye disease and his sight is very poor.One night, while filling out a form to get a guide dog, Shaw heard a news story on TV about people training horses to guide the blind.Shaw loves horses and wanted a guide animal that would live a long time, He applied (申请), and a year later, Cuddles and Shaw began training as a team.On a trip to New York, Cuddles helped Shaw safely tour Times Square, a very busy part of the city at night.The next day, Cuddles calmly rode the elevator with Shaw to the crowded top of the Empire State Building, a famous tall building.Cuddles even guided Shaw on the boat ride to the Statue of Liberty, and traveled on the subway system.Shaw says that he is very lucky to have Cuddles.He believes that Cuddles has changed his life for the better by giving him the chance to do things himself and making him feel much more confident about himself.语篇解读：本文是一篇说明文。
