人教版必修三第二单元语法情态动词用法归纳和练习Book3Unit2Grammar课件(共33张PPT)

人教版必修三第二单元语法情态动词用法归纳和练习Book3Unit2Grammar课件(共33张PPT)
【答案】A
【详解】 考查dare的用法。dare作为情态动词的用法是dare (not) do敢/不敢做某事 (有一般过去时),作为实义动词的用法是(not) dare to do敢/不敢做某事, 结合以上用法说明可知该题用dared not符合语法规则,此时的dared是情态 动词的过去时形式,其后接动词原形。故选A项。
3) 在表示“应该”方面 must, ought to, should 都能用来表示“出于某种职责、 义务而应该”的意思。must的语气最强烈,ought to居 中,而should是表达这方面意思的普通词。 如: You must cut down on smoking. You ought to visit your parents more often. You should try that new restaurant.

Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin’s work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.One day Merlin received an invitation to attend a fancy dress ball(化妆舞会). He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He thought he would get a lot of attention if he could skate into the room.Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forget Merlin’s grand entrance for a long time!30.The text is mainly about ____.A. a strange manB. an unusual partyC. how roller skating beganD. how people enjoyed themselves in the 18th century31.People thought Merlin was a dreamer because he ____.A. often gave others surprisesB. was a gifted musicianC. invented the roller skatesD. was full of imagination32.Merlin put wheels under his shoes in order to ____.A. impress the party guestsB. arrive at the party soonerC. test his inventionD. show his skill in walking on wheels33.What is the main point the writer is trying to make in the last paragraph?A.

He used to read whenever he was not doing something else. He found a book is especially useful during the periods of waiting: waiting meals, buses, doctors, haircuts, telephone calls and for something to happening. That was why he found fifteen minutes a day in reading. That was how he read his twenty books a year-one thousand book in a life time!人教版必修三Unit 2 Healthy eating3.
