一、含有名詞的固定搭配

四級完形填空經常出現的考點之一便是對固定搭配的考查,例如:動詞詞組、介詞詞組和名詞詞組。在上述三類詞組中,會出現交叉測試現象,即對同一詞組的考查,有時側重名詞,有時則側重介詞等?？忌杈邆渖詈裨鷮嵉幕A知識,注意在平時練習中對常見詞組進行積累,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:它測量被測試者腦電活動,其方式如同一些機器被用于醫(yī)療和研究一樣。正確選項應為D)。含有名詞的固定搭配在完形填空的測試中雖對考生對文章整體的把握要求較低,但對考生掌握英語固定搭配短語的質和量都提出了很高的要求,這也是對四級舊題型詞匯和語法部分的沿襲和延伸。
