storms.更加严峻的困难包括极冷的天气状况和巨大的风暴。1）difficulty既可作可数名词也可作不可数名词，在此用作可数名词。,Language points,作可数名词时，difficulty通常用作复数，表示具体概念，即：各种各样的“困难；难题；难事”。例如：People learning a new language may face some difficulties.人们学习一门新的语言时可能会遇到一些困难。If you have any difficulties,you can call me forhelp.如果你遇到任何困难，给我打电话。,作不可数名词时，difficulty可译作“困难；艰难；辛苦；费劲”，例如：He had great difficulty in finding a new job.他找新的工作费了很大劲。We found the house without difficulty.我们轻而易举地找到了那座房子。,2）include表示“包括；包含”，是一个及物动词。例如：Does your price of the bike include this light?你们的车价包含这盏车灯吗？,2.The spirit of these climbers shows us that we should never give up trying to achieve our dreams.这些登山者的精神向我们表明：我们绝不应该放弃实现自己梦想的尝试。1）give up doing something 的意思是“放弃做某事；半途而废”He gave up learning a third language after he gotthe job.他找到工作之后就放弃了对第三门语言的学习。,2)achieve our dreams 相当于make our dreams come true 其中动词achieve表示“（通过努力）实现；取得；获取；达到（梦想、成绩、成功、目的)”等。例如：He achieved great success in a short time.他用很短的时间取得了极大的成功。Lin Tao achieved very good exam results.林涛考试取得了很好的成绩。,3.Thick clouds cover the top and snow can fall very hard.Even more serious difficulties include freezing weather conditions and heavy

outside now.现在外面冷极了。Its very cold today,the temperature has dropped to freezing point.今天很冷，温度降到了冰点。,描述天气时，英语形容词与名词的搭配与汉语不尽一致，值得注意。此处thick clouds(密集的云层；厚密的云块)、freezing weather(极度寒冷的天气)和heavy storm(大暴雪/雨)就是颇具说服力的例子。与weather、storm、snow、cloud、air这五个本单元课文所出现的天气名词有关的部分描述性搭配：,表现“寒冷”时常与weather搭配的形容词：cold,freezing,icy 表现暴风雨之“凶猛”时部分与storm搭配 的常见形容词：bad,big,great,heavy,terrible,disastrous,fierce,tremendous,violent 表现snow之“强弱”时的搭配：heavy,thick,light,表现云层“疏密”时常与cloud搭配的形 容词：light,thick,heavy,dense表现“乌云”时cloud一词的常见搭配：black,dark,gray,dense表现空气“稀薄”、“浑浊”、“潮湿”时与air搭配的形容词：thin,thick,humid,4.It is also very hard to take in air as you get near the top.1)动词不定式在作主语时，常用it作形式主语，而往往将动词不定式放在谓语或表语之后。Its not easy to learn a foreign language well.=To learn a foreign language well is not easy.学好一门外语不容易。,2)take in 吸入；吞入(体内)take in:(to understand completely the meaning or importance of something)理解；领会；领悟Fish take in oxygen through their gills(鳃).I had to read the letter twice before I could take it all in.,最危险的运动之一2.登山，攀岩3.全世界4.中国的东南边境5.山顶,one
