Question

【题目】Directions: Read the following passage. Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.

As we all know that the biggest safety threat which faces airlines today may not be a terrorist attack with a gun, but the man with the portable computer in business class during the flight. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic (电磁)interference. The source of this interference remains unconfirmed, but increasingly, some experts are pointing the blame at portable device such as portable computers, radio and cassette players as well as mobile phones.

RICA, an organization which advises the aviation(航空)industry, has recommended that all airlines should ban such devices from being used during"critical "stages of flights, particularly take-off and landing. Some experts have gone even further, calling for a total ban during all fights. Currently, rules on using these devices are left up to individual airlines. And although many of the airlines prohibit passengers from using such equipment especially during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.

The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Some experts know that portable devices send radiation which affects those wavelengths that aircraft use for navigation and communication. But because they have not been able to reproduce these effects in a lab, they really have no idea whether the interference might be dangerous or not.

The fact that aircraft may be vulnerable(易受损的) to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions clearly to turn off his radio because the music is too loud. So it still takes time to impose a ban on the use of portable devices during flights. (total words 311)

Answer 1

【答案】Safety threat to airline may be the portable devices. RICA recommended a ban during important stages of flights. Some experts even require it during all fights. Many airlines prohibit it during take-off and landing, but not enforce a total ban. Besides, experts aren’t sure whether the interference might be dangerous . So it takes time to handle .

【解析】

本文为概要写作。本文首先要用不超过60个词来概括大意和要点，但不能用文章中的原句。

概要写作一般分为以下几步：

首先，弄清题目要求。概要应包括原文中的主要事实，略去不必要的细节；

第二，要细读原文，找出文章主旨和结构，析原文的内容和结构，将内容分项扼要表述并注意在结构上的顺序。用一些具有概括功能的词和句式，如各种复合句或非调语等对文章的具体信息进行概括、表述出来；

第三，列出原文要点。本文的要点需要包括（1）Safety threat to airline may be the portable devices.（航空公司的安全威胁可能是便携式设备）

（2）Many airlines prohibit it during take-off and landing（许多航空公司在飞机起飞和降落时都禁止这种做法）

（3）experts aren’t sure whether the interference might be dangerous（专家们也不确定这种干扰是否危险）

注意：

写概要时，要把文章的具体信息用一些具有概括功能的词和句表述出来，略去不必要的细节。不要抄袭原句，通过对文章中的单词、词组和句子进行合理转换，对文章的具体信息进行概括，再用合适的语言表述出来。切忌只简单地写出一些互不相干的句子，但也不要每两句之间都加关联词语，以免显得生硬。写作时注意抓住文章的主旨大意，避免逻辑混乱。概要应与原文一致，字数应在要求之内。
