雅思阅读多选题词汇题解析

小编要分享的是雅思阅读备考类：雅思阅读多选题词汇题解析

词汇题

词汇题对词汇的考查有两种:一是超纲词的含义推断,二是熟词僻义和熟词场合义.词汇感不是考词汇量有多大,而是主要考查是香读懂了上下文并具备结合上下文推测词义的能力.词汇题之所以归在阅读理解中,目的是考在考生对文章的理解.因此,做词汇题的方法就是通过认真阅读被考词周围的句子,尤其是该词前后的句子以及该词出现的句子的意义去推断.

例1

With as many as 120 varieties in existence,discovering how cancer works is not easy.

The researchers made great progress in the early 1970s,when they discovered that onco-

genes,which are cancer-causing genes,are inactive in normal cells.Anything from cosmic

rays to radiation to diet may activate a dormant oncogene,but how remains unknown.If

several oncogenes are driven into action,the cell,unable to turn them off,becomes cancerous.

Q:The word"dormant"in the paragraph most probably means

A.dead

B.ever-present C.inactive

D.potential

解析:dormant出现在第三句,第一旬"由于存在120多种高定,所以找到癌症起因并不容易.”对于猜词帮助不大、第二句"研究人员发现在正常细胞中,致癌基因并不活跃(inactive)."第三句“任何东西都可能激活致癌基因.但其内在机制仍不为人知.”第四句

"如果儿个致癌基因被激活,面细胞又不能将它们消灭,就会成为癌细胞.”据第二句、第三句推断“dormant”的意思与“不活跃”相近,故C正确
