商务英语阅读试题Part 3

Part III Reading comprehension Passage 1 Richard Brasher, commercial director of Tesco?s non-food operations, is in the frame for the top job at Boots, where chief executive Steve Russell is to step down. Brasher is understood to be on a shortlist that includes Stuart Rose, the former boss of retailing group Arcadia, the Terry Duddy, chief executive of catalogue retailer Argos. Brasher is viewed as a high-flier within Tesco and is highly rated by the group?s chief executive, Terry Leahy. Boots has been looking for a chief executive and a new chairman since the middle of December, when its current chairman, John McGrath, admitted that the group had not acted fast enough to address strategic issues that were facing it. McGrath is due to step down at the end of his contract in the summer, after overseeing the search for a new chief executive. Boots has been trying to find a way to distinguish itself and its products from the increasing range carried by supermarkets. Last week Sainsbury, the food retailer, said it would be extending its own health and beauty offering after it axed a joint venture trial with Boots. Sainsbury and Boots have been working together since 2001, but Sainsbury now wants to roll out its own programme in about 50 stores. Under the original trial, Boots supplied the products, including exclusive lines, to a specific area within Sainsbury stores at nine out-of-town supermarkets. Although both sides agreed initial targets had been met, they could not agree terms to take the scheme forward. Observers suggested that the two had disagreed over sharing revenues. Boots has confirmed the departure of another senior member of management. Michael Bunting, head of treasury, will leave the company in April. Other senior staff who have left recently include Barry Clare, marketing director, and Ken Piggott, who was managing director of Boots? core business. Questions 31-35 are based on passage 1 31. Boots, according to the passage, is _______. A. a person B. a supermarket C. a hotel D. a factory 32. Richard Brasher is to ________. A. become chief executive B. be on a shortlist C. be a high-flier D. work within Tesco 33. Brasher is _______. A. scolded badly by Terry Leahy B. highly assessed by Tesco?s chief executive C. valued greatly by Tesco D. understood by Tesco 34. Sainsbury is a ________. A. person who worked with Boots B. business that wants to work with Boots C. supermarket that has developed its own program all the time D. supermarket that stopped cooperation with Boots 35. It seems that ________. A. a lot of people left Boots B. Boots is thriving quickly C. Boots has decided to reform D. Some senior staff have left or will leave Boots

BEC真题阅读--part4--综合总结

BEC中级reading part4选词填空题巧解 阅读第四部分应试技巧—完形填空题 (一)题型介绍 BEC Vantage阅读第四部分不仅是考查对文章的理解,还考查语法、词汇和结构,如词的搭配、固定短语等。考生首先必须阅读文章,了解文章的大意,在这个基础上再根据上下文确定最佳选择。具体而言,这部分主要考查考生以下三个方面:一是语法知识,主要包括时态、语态、虚拟语气、从句、强调句、倒装句等 二是词汇,包括近义词、形近词、介词搭配、形容词搭配、动词搭配、名词搭配等; 三是考生对语篇的理解和推理能力。 (二)解题技巧 以下是这部分常见解题技巧: 1.排除无关选项:把握文章的主题,将一些看上去和文章主题毫不相关的选项排除在正确答案之外。 2.把握文章结构:充分利用文章结构来做出选择。譬如总分结构,总述是分述的总结和概括,而分述又是对总述的展开。当一些未知填空出现在总述中时,解出这些填空的相关已知线索很可能出现在与其对应的分述部分。 3.积累商务词汇: 4.从文章衔接入手:如果填空题中需填人的词为名词,还需要确定其单数或复数形式。要特别注意填空题后面的代词,每个代词都会表明它所代表的名词或名词短语。因此,找到填空题后面的代词,对确定所要填入的名词有很大帮助。如果是动词,也应确定其相应

的形式,如是否用第三人称单数等。 (三)答题步骤 考生可按以下步骤做题: 1.把握文章主旨:细读文章首句。与其他阅读部分不同,完形填空的第一句一般不留空白(或者空白处是例子,答案已给),是完整的一句,全文信息从此开始,通过该句预测文章主旨。然后,快速浏览全文,阅读时要一气呵成,尽管有空格、生词或不明白之处,仍要快速读下去;注意找出关键词、核心词,划出承上启下的词组,以便于抓住文章主旨和线索,形成思路。 2.灵活选择答案:注意从上下文及其逻辑关系人手寻找最佳选项。先读所填词的句子及其上下文。如果一句中有两处空白,在做题时要“双管齐下”,在两处同时试填,然后通读全句,确定答案。如果答案一时难以确定,可从语法结构、词语搭配、上下文语境、习惯用法、词义辨析等方面,对选项逐一分析试填,从而排除干扰项,判定最佳选项。 3.速读填好的短文:考生在检查已填好的文章时应注意上下文的一致性,即时态语态的一致,代词、连词、单复数的一致;注意语法、惯用法、习惯搭配,看是否符合上下文的逻辑;同时也应注意段与段之间、句与句之间的衔接是否自然、连贯。 常考点: 1、固定搭配,尤其是动词固定搭配 2、动词加副词性小品词搭配 3、词的辨析 4、选在商务英语中经常考察的词,不要选自己不认识的词,不要想得太复杂 5、常考词 1)Base \basis On the basis of\be based on\customer base\manufacture base\skill base\use base其他情况使
