Native English speakers can understand each other even if they dont speakthe same kind of English.这里的even if they dont speak the same kind of English是让步状语从句，整个句子可以翻译成“以英语作为母语的人，即使他们所讲的语言不尽相同，也可以互相交流”。even if等于even though，意思是“即使、尽管”，引导让步状语从句。Even if we have learned “even though” we still find it difficult to use.尽管我们学过“even though”，但我们还是发现运用它很难。Mr. Smith likes to help us even if/though he is very busy.史密斯先生虽然很忙，他还是愿意帮我们。2. It became less like German, and more like French because those who ruled England at that time spoke French.这里的because those who ruled England at that time spoke French是原因状从句，who ruled England at that time是定语从句，整个句子可以翻译成“它（英语）不那么像德语，而更像法语了，因为那时的英国的统治者讲法语”。3. Believe it or not, there is no such a thing as Standard English.这里的Believe it or not意思是“信不信由你、不管你信不信”，通常在句子中作插入语，有逗号和句子分开。such(. . . )as在这里相当于like或for example。整个句子可以翻译成“信不信由你，（世界上）根本没有什么标准英语”。Believe it or not, what I said just now is true.信不信由你，我刚才说的是真的。4. The US is a large country in which many different dialects are spoken.这里的in which many different dialects are spoken是由介词in+which引导的定语从句，修饰先行词country，介词in也可以放在定语从句中，即which many different dialects are spoken in。整个句子可以翻译成“美国是一个大国，国内说着许许多多的方言”。They went to a large garden in which were many green trees and red flowers.他们来到一个大花园，里面长着许多红花绿树。5. These men spent nearly all of their lives trying to collect words for their dictionaries.句子中的spend. . . (in)doing. . . 意思是“花费（时间等）干”，有时也用spend. . . on+n. 。整个句子的意思是“这些人几乎用了他们一生的时间为了编词典收集单词”。Now more and more city adults spend their leisure time trying to improve themselves at school or college.现在越来越多的城市里的成年人把他们的闲暇时间花在学校里提高自己。Mary spent 10 dollars on the new beautiful dress.玛丽花10美元买了这条漂亮的裙子。6. So why has English changed over time?句子中的over相当于throughout(a period)或during，意思是“贯穿（一时间段）”，所以整个句子可译成“那么，英语在一段时间里为什么会起变化呢？”。Over the years he has become more patient.这几年他越来越有耐心。Rick came to town over the weekend.瑞克周末到城里来过。7. Actually, it was based more on German than present day English.句子中base sth. on sth. (to use sth. as grounds, evidence, etc. for sth. else)，意思是“以某事物为另一事物的根据、证据等”，也常用be based on的形式。因此，该句可翻译成“实际上，当时的英语更多的是以德语为基础的，而现代英语不是”。He based his hopes on the good news we had yesterday.他把希望寄托在我们昨天得到的好消息上。This novel is based on fact.这部小说是以事实为根据的。Step 6 ConsolidationShow the exercises on the screen or give out test papers.1.
