請看下面的例子:there are social, medical and technical problems associated with the use of mobile phones. what forms do they take? do you agree that the problems outweigh the benefits of mobile phones?
這個題目中給出的話題是mobile phone,所以考生可以從它產(chǎn)生的原因來考慮,就是科技的繁榮,而科技的繁榮,手機(jī)的廣泛使用是在20世紀(jì)末,這樣背景句就有內(nèi)容可寫了。當(dāng)然要通過相應(yīng)的句型來寫了。如… (time) witnessed …這個背景句就可以寫成: the late 20th century witnessed the boom of science and technology, which gave rise to a series of technological innovations, including the mobile phone.
再看一例:nowadays, some universities offer students skills that assist them to find employment, but some people believe that the main function of a university should be to provide students with access to knowledge for its sake. what is your opinion?
這題要求大家討論培訓(xùn)中心是提供職業(yè)技能還是傳授知識。那從傳統(tǒng)觀點來看,培訓(xùn)中心是傳授知識的地方,為什么會提出要傳授技能呢,所以這里考生也可以用追根溯源法思考下,大家肯定可以想到是由于找工作已經(jīng)成為當(dāng)今教育的目的之一了,所以很多培訓(xùn)中心就轉(zhuǎn)移到以傳授技能為主了。那當(dāng)然還是要結(jié)合句型,這里可以用as 引導(dǎo)的原因狀語從句。參考:as job-hunting has become one of the main purposes of university education, the majority of the universities tend to offer vocational trainings to prepare the students for their future career.
