I find that many learners have an obsession(困扰) with slang and idioms,as if repeating some very colloquial expressions is going to upgrade how they sound in a language.In fact it is the opposite.Idioms are difficult to use correctly.They can easily sound very strange coming from someone who obviously does not have a good sense of the language. Yes,occasionally you hear idioms or slang and do not understand.But,in my experience,there are always situations where you do not understand.It is best to focus on the most important words,what they mean and how they are used.Certainly,it is best for a non-native speaker to stick to standard speech. Some teachers even try to teach the “real language”.Then you hear non-native speakers saying things like “I gonna” ,“You wanna” etc.I just cringe(厌烦). You will learn all the idioms you need just by exposing yourself to the language.In general,you can save any phrase that you find interesting,and if that includes idioms,go to it.But I would not make any special effort to go after idioms.I,in fact,avoid them.If I come across something in Russian that strikes me as a particularly slangy or idiomatic use of words,I just leave it aside; do not even bother trying to learn it.If it keeps on appearing,then I will learn it.But I would certainly be reluctant(勉强的) to try to use it. 1.In the writer's opinion,when one learns a new language,one should learn its idioms ________. A.at the beginning B.on one's own C.in the end D.without help 答案与解析:C 细节理解题。从第一段中的“To me they are kind of...They come at the end of a meal.”可知。 2.The underlined word “colloquial” in Para.2 means “________”. A.oral B.informal C.formal D.written 答案与解析:A 词义猜测题。从画线词后的upgrade how they sound in a language,特别是sound一词可知colloquial 的意思是“口语的”,故A项符合语境。 3.It can be inferred from the passage that________. A.idioms are the most important part in a language B.the writer is not very willing to use idioms C.non-native speakers should learn more idioms D.there are no ways to master idioms 答案与解析:B 推理判断题。从第一段提到的最后学idioms和最后一段中的I would not...go after idioms,avoid them(idioms)及be reluctant to try to use it 可知答案为B。 4.Which of the following is the best title of the passage? A.It's better to avoid idioms in a language B.Idioms are very charming in a language C.How to learn idioms in a language D.Why it's difficult to use idioms in a language 答案与解析:C 标题概括题。从全文尤其是首段第一句话可知作者是在讲述如何学习一门语言中的习语。 5.How did the writer develop the passage? A.By inferring. B.By comparing. C.By listing examples. D.By giving explanations. 答案与解析:D 篇章结构理解题。综观全文可知,作者是通过逐段解释与说理来展开文章的,故D项正确。
