D、" We present a new optical-probe (光学探子) technique based on light-scattering spectroscopy (分光镜检查) that is able 【55】 detect precancerous and early cancerous cells in cell-rich epithelia," he added in a statement.The new technique relies on the fact 【56】 cell nuclei change in the early stages of cancer and the differences scatter light in a characteristic way. Until now the changes were only detectable 【57】 a biopsy (活检) was taken, the scientists sai

The tip of the optical probe was brought into contact with the tissue to be tested and the scattering of light was recorded without the need for any tissue to be 【62】 , the scientists sai
D、" Our results show that light-scattering spectroscopy has the potential to detect pre-cancerous body damages and preinvasive cancers throughout the body. This technique should 【63】 improve the efficiency of cancer screening and surveillance," the scientists sai

网考网解析：
考虑到空白处后面已有介词with，而所列选项中A)项“contract”只有当不及物动词用时才能与with连用，意思是“与…签合同”，此处是过去分词作定语(当及物动词用)，故可排除之；B)项“issue”只有当名词用时才可与with连用，意为“与…争辩”，此处为过去分词，也可排除之；D)项“cope”是不及物动词，可与’with连用，意为“对付，处理”，虽然用现在分词coping符合语法，但意思不对，也可排除之；只有equip是及物动词，可与with连用，意为“装备，配备”，用过去分词“equipped”也符合语法，又符合上下文意思，故是最佳选择。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
