Unit 12 What did you do last weekend? Section B 教材知识全解 讲透知识 查漏补缺 知识点一 由 put up 归纳常见的 put 短语 教材原文 There we put up our tents and made a fire to keep us warm and cook food on.在那里我们搭起帐篷,生火取暖并做饭. put up是固定搭配,意为“搭起;举起”.如: The box is too heavy. I can't put it up.那个箱子太重了,我举不起来. It's going to rain. Let's put up the tent.天要下雨了.我们把帐篷搭起来吧. 拓展put up还有“张贴”之意.如: They put up a notice on the wall.他们在墙上贴了一则通知. 归纳常见的put短语有: put up 搭起; 举起;张贴 put on 穿上,戴上;表演 put away收起来 put down放下;记下 put off推迟;拖延 put out 熄灭;扑灭 例(2020湖南郴州期末教学质量检测)-Hi, John. Could you come and help me________ the tent? -Sure, no problem. A. cut up B. wake up C. put up 解析 根据本题语境可知,问句问的是“你能来帮我把帐篷搭起来吗?”,put up符合题意. 答案 C 知识点二 surprise的用法和延伸 教材原文 The next morning, my sister and I got a terrible surprise.第二天早上,我和我姐姐大吃一惊. surprise作名词,意为“惊奇;惊讶”,可以作可数名词,也可以作不可数名词.如: He looked at me in surprise.他惊讶地看着我. What a surprise! He won first prize of the competition.太令人惊讶了！他赢得了比赛的一等奖. 拓展surprise还可以作动词,意为“使吃惊;使惊讶”,通常作及物动词,其后可以直接跟宾语.如: His story surprised everyone.他的故事使每个人都惊讶. 延伸surprise的常见短语和派生词有: get a surprise 吃惊;惊讶 in surprise 惊讶地;吃惊地 to one's surprise 令某人惊讶的是 surprising adj.令人惊讶的(用来修饰事或物) surprised adj.感到惊讶的(用来修饰人) 例(2020河北石家庄精英中学第二次限时练)根据句意和首字母提示写出所缺的单词 We got a s________ that he didn't pass the exam. 解析 本题考查surprise的写法.根据“他考试没有及格”可推断,我们很“惊讶”,所缺的词是surprise. 答案 surprise 知识点三so...that...引导的结果状语从句 教材原文 I was so scared that I couldn't move.我太害怕了,以至于无法动弹. 本句是含有结果状语从句的主从复合句,so...that...意为“如此······以至于····”,so后面跟形容词或副词.如: The boy is so young that he can't go to school.这个男孩太小还不能去上学. 注意含有so...that...结构的句型可以转化为too...to...结构的句式.如: The girl is so short that she can't reach the top of the shelf.＝The girl is too short to reach the top of the shelf. 那个女孩个子太矮了,够不着架子的顶端. 例改为同义句 The car is too expensive for me to afford it. The car is________ expensive________ I can't afford it. 解析本题考查so...that...和too...to...的同义转换. 答案 so; that 单元语法全解 熟悉句型 把握要领 一般过去时(II) 本单元的语法仍然是一般过去时,侧重行为动词的一般过去时的特殊疑问句.具体如下: (1)对人物进行提问时有两种情况: 如果人物作主语 Who+行为动词的过去式＋其他? 如果人物作宾语 W
