1、高中二年级英语学案Units 7-8 (B2)【知识网络】一、重点词汇与短语1lack（1）lack表示 “缺乏; 欠缺”之意时可作及物与不及物动词.作不及物动词时常与介词for连用. 例如:I dont seem to lack anything.我好像什么也不缺.They lacked for nothing.他们什么都不缺.（2）作为一个不及物动词, 用于 “缺乏或缺少”之意的lack, 主要和in一起用于现在分词. 例如:You will not be lacking in support from me.你会得到我的帮助.（3）lack作名词表示 “欠缺; 不足; 没有”时, 常为不

2、可数名词, 后接介词of. 例如:He cannot do the work for lack of skill.由于缺乏技术, 他不能做这项工作.（4）lack作名词表示 “缺少的东西; 需要的东西”时, 常为可数名词. 例如:There has been a lack of rain and the ground is very dry.此地缺少雨水, 地面非常干燥.（5）习语: for (by, from, through) lack of因缺乏lack in在缺少/不足no lack of不缺乏; 很多.supply the lack补缺（6）同义词: need n需要反义词: pre

3、sence n存在2英语中的 “同源宾语”现象英语中有少数不及物动词后面能跟一个特定的名词作宾语. 这个名词和前面的动词在词根上是相同的或者在意义上是相近的. 这样的宾语就叫做同源宾语.（1）常见的能带同源宾语的动词有: live, die, sleep, dream, breathe, smile, laugh, fight, run 等. 例如:Under the leadership of the Party, the peasants are living a happy life.在党的领导下., 农民过着幸福的生活.I dreamed a terrible dream last n

4、ight.昨晚, 我做了一个噩梦.Our soldiers fought a wonderful fight against the floods last August.去年八月份, 我们的战士在与洪水作斗争时, 打了一个漂亮仗.（2）同源宾语前面可带形容词作定语. 这时, “动词+定语+同源宾语”的结构在意义上相当于 “动词+与定语意义相同的状语”. 二者相比, 前者语气更强一些. 例如:We slept a comfortable sleep last night. =We slept comfortably last night.昨晚我睡得很舒服Professor Smith died

5、 a sudden death last Wednesday. =Professor Smith died suddenly last Wednesday.史密斯教授上星期突然去世了.注意同源宾语前通常带有不定冠词. 例如: fight a good fight; breathe a deep breath; laugh a foolish laugh; smile a forced smile.（3）同源宾语的修饰语是形容词最高级或含有最高级意义时, 该同源宾语常常可以省去. 例如:You should run your fastest (race).你应该尽快地跑The old man b

6、reathed his last (breath)this morning.那位老人今天早晨停止呼吸, 撒手西去了.二、词义辨析1英语中via, by way of, through三个词都可以表示 “经过; 经由;”, 区别如下:2（1）via这个词的词义是 “经过; 取道” (by way of). 常与travel, shipping等词连用. 例如:Mr Wang is on his way to Hangzhou via Shanghai 王先生在经由上海前往杭州途中. 注意A. 美国人也常将其用于表示通过某种运送手段或交通工具的意思, 相当于by. 例如:You are going

7、 via car or railroad?你打算乘汽车还是坐火车去.这种用法在美国用于正式的场合. 例如:Via Air Mail (航空邮递; 英国人则用By Air Mail).B此外, 美国人还把via作为 “用”的意思使用; 相当于by means of. 例如:An American officer pleaded vainly with him via radio to turn back.一个美国军官用无线电向他恳求要他回来; 但没有结果.（2）by way of等于via, 意思也是 “经由; 经过”(using a route through), 二者常可以互换. 例如:He

8、 went to Hangzhou by way of Shanghai,他经由上海前往杭州.By way of其他常用的意思如下:A表示 “当作”, 相当于as. 例如:Fred was employed by way of experiment弗雷斯是作为试用而雇佣的.B表示 “作为, 为了”, 即for the purpose of, with the intention of. 例如:We make inquiries by way of learning the facts of the case.我们为了了解事情的真相而进行探询.I called on him by way of

9、returning compliments.作为回访, 我拜访了他.C表示 “有的习惯”, 即in the habit of. 例如:The Greens were by way of luring me away from my duty.格林一家惯于引诱我离开职守.（3）through的意思是 “通过”, 在乘坐火车, 轮船且全线不换车船时用.例如:He went to Hangzhou through Shanghai.他途径上海直达杭州3proper, fit suitable和appropriate的区别这几个词语都有 “合适的; 恰当的”意思.（1）fit是常用词, 指 “能适合某

10、些条件, 环境, 目的 或要求的”, 有 “吻合的”含义. 例如:The dress is not fit to wear.这衣服不适合穿.（2）suitable指 “符合某时或某一环境下的要求或需要的”. 例如:The shoes are suitable to travel.这鞋适于旅游.（3）proper指 “正当的; 正确的”. 例如:Fill in the blanks with proper words.用适当的词填空.（4）appropriate指 “恰如其分的”, 比fit和suitable有更强的正面意义. 例如:His quotation from Shakespeare

11、is appropriate.他引用沙士比亚的话恰如其分的.三、重点句型1If we were to get hurt trying to save someone, we would not be able to help. 如果我们在试图救某人时受了伤, 我们就不能帮助别人了.get hurt意为 “受伤”. “get+过去分词” 是一种被动语态形式, 强调动作. 如:Our team got beaten by the visitors.trying to save someone是现在分词作时间状语, 相当于when we were trying to save someone. 现在

12、分词作时间状语通常放在句首, 但也可放在句末. 如:He got knocked down by a car crossing the main street.2Seconds count in an emergency, and knowing what to do can mean the difference between life and death. 在紧急情况下, 每秒钟都是重要的, 懂得应做些什么可能意味着生死之差别.knowing what to do 是动名词短语作主语. 又如:Being short of money led to the failure of the p

13、lan.3“If I were to live long enough to have a job, I would choose to be a doctor, helping these ALDS patients,” Xiaohua says. 小华说: “如果我能活到参加工作, 我要选择医生这个职业, 帮助这些艾滋病患者.”I were to live是虚拟语气. 在虚拟语气中, 不管主语是第几人称, be动词一般都要用were.If I were you, I would accept his offer.helping是现在分词作状语, 表示补充说明. 如:He wrote me

14、a letter, encouraging me to study hard.【考点透视 考例精析】考例1 Why did you leave that position? I _ a better position at IBM.
