Unit 8 Have you read Treasure Island yet? Section A 教材知识全解 讲透知识 查漏补缺 知识点一(be)full of 的用法 教材原文 Oliver Twist is about a boy who goes out to sea and finds an island full of treasures.《雾都孤儿》是关于一个男孩的故事,他出海,然后找到了一个满是宝物的岛. (be)full of意为“满是·····的”,其中full是形容词,意为“满的”. The box is full of old toys.这个箱子装满了旧玩具. 温馨提示 full还可表示“吃饱了的”.如:Thank you. I'm full.谢谢,我饱了. 拓展full的延伸 empty adj.空的 hungry adj.饿的 fill v.使填满;使充满 fill...with...用······装满······ be filled with...装满(＝be full of) 例1(2020山西晋城高平期末)He was very excited and his eyes were________ of tears when he saw the good news. A. full B. prepared C. filled 解析 句意:当他看到这则好消息时,非常激动,眼里充满了泪水.短语be full of=be filled with,表示“充满”,故选A. 答案 A 知识点二 already与yet的用法区别 教材原文 I've already finished reading it!我已经看完它了！ 本句用了现在完成时,already是副词,表示“已经”,通常用在现在完成时的肯定句中. We have already cleaned the classroom.我们已经把教室打扫干净了. 辨析 already和yet都是表示时间的副词,区别如下: Already 可以用在现在完成时或一般现在时的肯定句中,already一般位于助动词或be动词之后,行为动词之前,还可以位于句尾 Yet 多用在现在完成时的否定句或疑问句中,yet通常位于句尾 I have already finished my homework.我已经完成我的作业了. Supper is already ready.晚餐已经准备好了. -Have you finished your homework yet?你已经完成作业了吗? -No, I haven't finished it yet.不,还没完成. 例2 (2020安徽钢陵枞阳自梅中学期末)I have________ decided when to leave, but my sister hasn't decided________. A. yet; yet B. already; already C. already; yet D. yet; already 解析 句意:我已经决定何时离开,但我的妹妹还没决定呢.already多用于现在完成时的肯定句中;yet多用于现在完成时的否定句或疑问向中,通常位于句尾. 答案 C 知识点三 hurry up的用法 教材原文 You should hurry up.你应该快点. hurry up是固定搭配,意为“赶快;急忙(做某事)”,其中hurry是动词,意为“匆忙;赶快”.该短语与be quick是同义表达. Hurry up, or else you'll be late.快点,否则你就要迟到了. 拓展 hurry还可以作名词,意为“匆忙”.in a hurry 意为“匆匆忙忙”. You will make mistakes if you do things in a hurry.如果你匆匆忙忙地做事,那你就会出差错. 温馨提示 hurry表示匆忙到某处去,hurry之后直接跟表示方向的副词或介词短语即可,习惯上不接go、come、move等表示运动方向的动词.例如: 匆匆忙忙吃完早餐,他就赶到车站去了. 误:After a quick breakfast, he hurried to go to the station. 正:After a quick breakfast, he hurried to the station. 例3-________ ,let's help the blind man. He is lying on the road. -OK. I'm coming. A. Hurry up B. Come around C. Cheer up D.
