第一周的生活过的有一点困惑。

First, I had to think very carefully about which courses I wanted to take. The school adviser helped me choose the suitable ones: maths, English, chemistry, world history, and Chinese. I know Chinese is a very difficult language, but I hope to be fluent when I graduate. My adviser recommended that I should sign up for advanced literature because I like English and I'm good at it.词汇自测④fluent adj.

welcome．/It's nothing．/That's all right．/Don't mention it．/It's a pleasure．/It's my pleasure．/That's nothing/It was no trouble at all．等．C项意思是"不麻烦，没什么，这不费事，容易得很"．A项意思为"乐于效劳"；D项"当然可以；一定，务必"，表示同意等；B项"不要紧，没关系"．句子表达的意思是：﹣我们必须感谢你为我们做了一顿饭．﹣一点也不麻烦．故选：C．【点评】情景对话题主要考察英语的日常用语、习惯用语以及各种场合的交际性语言，并从实际出发，考查交际语言的运用能力．做题时仔细阅读上下文，找出上下文之间的联系．2．﹣Excuse

funC．What great fun D．How great a fun【分析】看一场势均力敌的足球比赛是多么快乐的一件事啊！【解答】答案：C．根据句意可知这里使用感叹句，what修饰名词，fun是不可数名词，不能用不定冠词a，排除AD；how修饰形容词或副词．故选C．【点评】由what 引导的感叹句，其句子结构可分为以下三种：1．可用句型：" What + a/an +形容词+可数名词单数+主语+谓语！"．2．可用句型：" What +形容词+可数名词复数+主语+谓语！"．3．可用句型：" What +形容词+不可数名词+主语+谓语！"．二、由how 引导的感叹句，其句子结构也分为三种：1．可用句型：" How +形容词/ 副词+主语+谓语！"．2．可用句型：" How +形容词+ a/an +可数名词单数+主语+谓语！"．3．可用句型：" How

where【分析】这个是上周一些德国朋友参观的学校吗？【解答】答案：B．根据句意和结构可知这句话是一般疑问句，主语是this，is是系动词，表语是this school，后面接省略定语从句，因为visited后面缺点宾语，用that/which或省略关系代词．故选B．【点评】本题考查定语从句，找到先行词，判断定语从句中缺少什么成分，这句话是疑问句，容易将主语this弄丢，注意分析句子成分．5．If you don't go there，________．（）A．so will I B．nor do IC．neither shall I D．so do I【分析】如果你不去那里，我也不去．【解答】答案：C 考查倒装句．由于从句If you don't go there是否定句，主句也应用否定句，排除A、D项；在条件状语从句中，主句用一般将来时，从句用一般现在时，排除B项，只有C项正确．故选：C．【点评】考查倒装句，要弄清楚各种倒装句的构成的原因，然后根据上下文及结合语境给出正确答案．6．The radio set _____ last week has been out of order．（）A．I bought B．I bought itC．which I bought it D．what I bought【分析】考查定语从句，句意：我上周买的收音机已经出故障了．【解答】答案：A，先行词为the radio，在定语从句中作bought的宾语，用that或which 引导定语从句，that或which省略了．所以选A．【点评】做定语从句题时：我们可先将不是关系代词或关系副词的选项去掉，然后采用"代入原则"并同时结合定语从句的关系词之间的相关区别来进行解题．所谓"代入原则"就是试着把先行词即被定语从句修饰限制的那个词放进从句中，能直接代入的就用关系代词（不包括whose），不能直接代入的可能有三种情况，要么用关系副词，要么用介词加关系代词which或whom，要么就用关系代词whose．7．The

D．the；a【分析】句意：史密斯夫妇一般不喜欢呆在酒店，但是去年夏天他们在海边一家很不错的酒店住了几天．【解答】答案：C．根据句意：hotels这里表示泛指，用名词复数即可．后一空by sea 是坐船，通过海路；by the sea 是在海边．旅馆应该是在海边的．故选：C．【点评】本题考查冠词的用法，答题时要分区by sea 和by the sea的意思．8．Dorothy was always speaking highly of her role in the play，___________，of course，made the others unhappy．（）A．who B．which C．this D．what【分析】Dorothy总是高度表扬自己在戏剧中的作用，这件事情大人让其他人不高兴了．【解答】B考查定语从句．在定语从句中which指代一句话的内容在句中做主语，引导非限制性定语从句．句意：Dorothy总是高度表扬自己在戏剧中的作用，这件事情大人让其他人不高兴了．故B正确．【点评】定语从句又称为形容词性从句，综观历年高考试题，我们可以发现该语法项目是测试中的热点与难点，解定语从句的题目首先要知道哪一句是主句，哪一句是从句，被修饰的词是谁，从句中的句子成分缺失什么，根据缺失成分的不同从而选出相对应的关系代词或者关系副词，从而选出正确的答案，解题的关键是从句句子的成分分析．9．﹣Do you need any help，Lucy？﹣﹣Yes，the job is _____I could do myself．（）A．less then B．more thanC．no more than D．not more than【分析】﹣﹣Lucy，需要什么帮助吗？﹣﹣是的，这份工作我自己独自做不来．【解答】答案：B．less than少于；no more than无非，只不过；not more than不多于，至多；more than之后的从句含有can或could时常表示否定意义．此时，从句中的谓语动词必须是及物动词，并且与主句的主语为逻辑上的动宾关系．根据第二句中的yes可知，对方需要帮助，所以应该是这个工作超过了他个人的能力；故选B．【点评】本题考查程度副词的特殊用法．在辨别不同短语意义的基础上，再联系句子的语境和句子所表达的含义，从而选出正确的答案．10．You are not polite enough．When you serve customers，you don't turn your head your body towards them．（）A．either B．or C．not D．neither【分析】你不够礼貌．当你为顾客服务时，不能把你的头或身体对着他们．【解答】答案：B．考查连词．either意为或是，或者，与or连用；or意为或，或者；not 是副词；neither意为既不……也不……，与nor连用．根据句意：你不够礼貌．当你为顾客服务时，不能把你的头或身体对着他们，可知or符合句意．故选：B．【点评】连词的选择首先要准确理解句子意义，然后辨析连词的意义，句意加连词意义才能做出正确选择．11．Don't worry，I won't tell your mother you've been punished in school．Yousee，．A．It's none of your businessB．I feel on top of the worldC．my lips are sealedD．I'm all thumbs【分析】别担心，我不会告诉你妈妈你在学校受到了惩罚，我保守秘密．【解答】答案C 本题考查交际用语．根据题意说话人是对对方做出承诺，不会泄露秘密．A 不关你的事．B 我感觉飞上天了．D

Section ⅡReading and Thinking基础知识预习自检中国书写体系：连接过去与现在尽管在历史的长河中有盛有衰，中国古文明一直流传至今，并被世界广泛认识。

中国古文明之所以广泛流传的原因有很多，但其中最主要的因素是中国的文字体系。

在一开始，中国文字是以图画为基础的。

这可以追溯到几千年以前使用龙骨的时期——被古代中国人刻上了符号的动物骨头或贝壳。

一些古代的符号在今天的汉字中仍然能看到。

到商朝(约公元前1600～1046年)时这些符号已进一步发展成了完善的文字体系。

历经时代发展，这个文字体系发展成不同的形式，因为当时的中国人口按地域被划分开来，导致人们说不同的方言，写不同的文字。

然而，秦王朝(公元前221～207年)的秦始皇改变了这一切。

秦始皇统一了七个主要国家之后统一了中国文字。

文字体系对于统一人民和文化非常重要。

即使在今天，无论中国人住在哪里，说什么样的方言，大家都能用文字沟通交流。

中国文字也成为连接中国过去和现在的重要方式。

现代中国人能够阅读古人撰写的经典作品。

中国文字体系所受到的高度重视体现在汉字发展为一种艺术形式：书法，并成为中国文化的重要一部分。

如今，中国文字体系仍然是构成中国文化的重要部分。

随着中国在全球事务中扮演着更为重要的角色，越来越多的国际学生开始通过汉语这一奇妙的语言来欣赏中国的历史和文化。
