Unit 6 When was in invented? Section A 新知点拨 ▶1.pleasure ①意为“高兴;愉快”,是不可数名词.例如: It gives us much pleasure to talk with you.与你谈话(我们)很愉快. ②表示具体的“乐事”“愉快的活动/经历”等时是可数名词.例如: It is a pleasure to talk with you.与你谈话是一件乐事. 【拓展】pleased 形容词,意为“高兴的,满意的”;pleasant 形容词意为“使人高兴的,讨人喜欢的”. ▶2.remain 不及物动词,意为“留下,剩余;保持不变”. ①表示“留下”“逗留”,特指在他人走后留下.例如: They went, but I remained.他们走了,但我留了下来. ②表示“尚待”“留待”,后面接被动语态的动词不定式.例如: One problem remains to be solved.有一个问题尚待解决. ▶3.invent 作动词,意为“发明,创造”;invention 作名词,意为“发明”;inventor作名词,意为“发明家;创造者”.例如: The great inventor has invented many great inventions.这个伟大的发明家发明了许多伟大的发明. ▶4.by accident 与 by mistake 的区别 by accident 意为“意外地(无主观意识,很客观的意外)”.by mistake也表示“意外地”,但更强调是无意识犯的错(带有主观色彩).例如: I took away his book by mistake.我错把他的书拿走了.(无意识犯错把他的书当成自己的书拿走了) I took away his book by accident.我意外地拿走了他的书.(不是因为误认为是自己的书而拿走的) 名师讲坛 一般过去时的被动语态 (一)构成:主语＋was/were动词的过去分词.例如: The TV was invented in 1927.电视于1927年被发明. (二)将一般过去时的主动语态变为被动语态时需要注意以下三个方面: 1.将主动语态的宾语改为被动语态的主语; 2.将主动语态的谓语动词改为”was/were+过去分词”结构; 3.将主动语态的主语改为介词by之后的宾语,放在谓语动词之后(有时可以省略).例如: They built a school in our hometown.他们在我们家乡建了一所学校.(改为被动语态)→A school was built(by them) in our hometown. 自主探究 一、阅读1a,听1b的材料,根据其内容填空.
