GRE閱讀長難句重磅解析(24)
the molecular approach to detecting peptide hormones using cdna probes should also be much faster than the immunological method because it can take years of tedious purifications to isolate peptide hormones and then develop antiserums to them. (4)
采用cdna探子來測定肽激素的這一分子生物學(xué)方法同時(shí)也應(yīng)該比免疫學(xué)的方法速度來得快,因?yàn)閷τ诿庖叩姆椒▉碚f,需耗費(fèi)好幾年枯燥的提純進(jìn)程,方能將肽素分離了出來,然后再培養(yǎng)出針對它們的抗血清。
難句類型:
復(fù)雜修飾、易混指代
解釋:
主語后的修飾成分同樣隔開了主語和謂語,但本句的難度主要在because從句中。按照一般的習(xí)慣,作為從句主語的it應(yīng)該指主句的主語,但本句的主句是一個(gè)比較結(jié)構(gòu),a should be faster than b because it…,此處it也可以指b。但是因?yàn)檫@種指代不符合和我們以前所形成的習(xí)慣,所以閱讀現(xiàn)場不得不邊讀邊根據(jù)句意來判斷,這就增加了閱讀理解的難度。現(xiàn)場閱讀時(shí),類似antiserums的這種專有名詞不必理會,僅需從詞頭anti推出這是一個(gè)反p荷爾蒙的東西即可。
