利用題干句中的特征詞 two LEDs搜索原文,發(fā)現(xiàn)他們出現(xiàn)在原文第三段后半部分內(nèi)容是關(guān)于兩個(gè)發(fā)光二極管在鼠標(biāo)中的具體工作方式。第三段說(shuō)道:鼠標(biāo)的部件有滾動(dòng)部件如滾球,還有光電裝置如二極管等。二極管將光信號(hào)轉(zhuǎn)換為電信號(hào),傳送到計(jì)算機(jī),計(jì)算機(jī)根據(jù)收到的電信號(hào)作出相應(yīng)的反應(yīng),因此,二極管是鼠標(biāo)的主要部件,而滾輪等只是輔助性的機(jī)械部件。題干句對(duì)短文信息的推斷是正確的。
