一、含有名詞的固定搭配

四級(jí)完形填空經(jīng)常出現(xiàn)的考點(diǎn)之一便是對(duì)固定搭配的考查,例如:動(dòng)詞詞組、介詞詞組和名詞詞組。在上述三類詞組中,會(huì)出現(xiàn)交叉測(cè)試現(xiàn)象,即對(duì)同一詞組的考查,有時(shí)側(cè)重名詞,有時(shí)則側(cè)重介詞等?？忌杈邆渖詈裨鷮?shí)的基礎(chǔ)知識(shí),注意在平時(shí)練習(xí)中對(duì)常見詞組進(jìn)行積累,例如:beyond one's means(不能用measure,也不能用method,更不能用approach)；by mistake (這個(gè)短語就不能說成by error或者by fault)；in the long run (而不是period, interval或time)等等。

Sleep Smart records the distinct pattern of brain waves produced during each phase of sleep, via a head-band equipped with electrodes (電極) and a microprocessor. This measures the electrical activity of the wearer's brain, in much the same way as some machines used for medical and research , and communicates wirelessly with a clock unit near the bed. You program the clock with the latest time at which you want to be wakened, and it then duly (適時(shí)地) wakes you during the last light sleep phase before that.

A) findings ?B) prospects

C) proposals D) purposes

[解析]此題是對(duì)名詞的考查。固定搭配for ... purpose 表示"被用于......目的"。此句句意為:它測(cè)量被測(cè)試者腦電活動(dòng),其方式如同一些機(jī)器被用于醫(yī)療和研究一樣。正確選項(xiàng)應(yīng)為D)。含有名詞的固定搭配在完形填空的測(cè)試中雖對(duì)考生對(duì)文章整體的把握要求較低,但對(duì)考生掌握英語固定搭配短語的質(zhì)和量都提出了很高的要求,這也是對(duì)四級(jí)舊題型詞匯和語法部分的沿襲和延伸。
