Unit 5 Why do you like pandas? Section B 教材知识全解 讲透知识 查漏补缺 知识点一get lost的搭配· 教材原文Elephants can walk for a long time and never get lost.大象能够长时间行走,而且从不迷路. get lost是固定搭配,意为“迷路”,和 lose one's way、be lost是同义表达.如: He never gets lost.他从来不会迷路. 例(2020四川天府新区六校期中)-Excuse me, where is the bus stop? I think I_________ . -Sorry, I don't know. I'm new here. A. get up B. get lost C. get dressed 解析 本题考查get短语.get up起床,起来;get lost迷路;get dressed穿上衣服.根据本题语境可知,我觉得我“迷路”了,get lost符合题意. 答案 B 知识点二 含with的介词短语 教材原文 They can also remember places with food and water.它们还能记住那些有食物和水的地方. 本句中的with food and water是介词短语,作后置定语,修饰名词places, with是介词,意为“带有;具有”.如: He is a man with long hair.他是一个留长发的男人. We want to buy a house with a garden.我们想要买一所带花园的房子. 例(2020广东广州明德实验学校期中改编)Sarah marries a man_________ a lot of money. A. has B. have C. on D. with 解析 句意:萨拉和一个有很多钱的男人结婚了.此处要填的是介词,先排除A和B项;with a lot of money 意为“拥有许多钱”,此时with的含义是“带有;具有”. 答案 D 知识点三 be in(great)danger的用法 教材原文 But elephants are in great danger但是大象正面临巨大的危险. be in(great)danger是固定搭配,意为“处于(极大的)危险之中”.in danger 意为“处于危险中”,其中danger作不可数名词,意为“危险”.如: These animals are in danger.这些动物处于危险中. You should ask police for help when you face danger.当你面临危险的时候,你应该向警察救助. 拓展danger的延伸 in danger 处于危险中 out of danger 脱离危险 反义词:safe adj.安全的 派生词:dangerous adj.危险的 例(2020山西太原志达中学四月月考)The virus(病毒)is_________. People will put themselves_________ if they go out without any protection(保护措施). A. dangerous; in danger B. in danger; dangerous C. dangerous; dangerous 解析 句意:病毒很危险.如果人们在没有任何保护措施的情况下外出,他们将会使自己处于危险境地.第一个空要填形容词dangerous“危险的”;第二个空要填in danger“处于危险中”,故答案为A. 答案 A 知识点四 cut down的用法······ 教材原文 People cut down many trees so elephants are losing their homes.人们砍伐许多树木,所以大象正在失去它们的家园. cut down 是固定搭配,意为“砍倒;砍伐”. 如果其宾语是名词 该名词宾语可以位于cut和down之间,也可以位于down之后 如果其宾语是代词 该代词宾语只能位于cut和down之间 They are going to cut down the trees/cut the trees down.他们打算砍伐这些树木. We don't want to cut them down.我们不想砍伐它们. 拓展常见的“动词＋down”的短语还有:come down下来,下降;sit down坐下;look down向下看;put down放下,记下;write down写下,记下;turn do
