19、, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move. B

The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.Prof. Millan, the team leader, s

22、ays scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

23、He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.21BCI is a technology that can _Ahelp to update computer systemsBlink the hu

27、一家咖啡店，故應(yīng)選went。3Ato sit at作tables的后置定語，意為“可以在旁邊就座的桌子”。4C按常理“我”應(yīng)把報紙等放在桌子上，而不是“推到”或“拉到”桌子上，故應(yīng)選 put。5C由下文可知，回來時“我”發(fā)現(xiàn)他開始吃“我”的東西，說明他坐在旁邊的座位上，故選 sitting。6B用it指代前文中未知的人。7D頭發(fā)應(yīng)是被染成艷紅色的，故應(yīng)選colored。8B面對這樣一個人，“我”不想惹麻煩，trouble合乎文意，為正確選項(xiàng)。9C由下文可知，“我”吃的是這個男孩正吃的巧克力，這引起了對方的某一反應(yīng)。比較四個選項(xiàng)，再根據(jù)上下文，用名詞surprise比較合乎當(dāng)時的情形。10B“a

28、 序數(shù)詞名詞”常用來表示“再一個，又一個”，與下文took a third piece相呼應(yīng)。11A根據(jù)文意可知那個男孩起身要走，故選擇stood。12B男孩生氣了，必定說了發(fā)泄的話，比較四個選項(xiàng)，wrong為最佳選擇。13B男孩罵了“我”，導(dǎo)致大家都朝“我”看，而“我”不想與他爭吵，可見“我”的反應(yīng)與上文描述的氣氛恰恰相反，故選擇but構(gòu)成轉(zhuǎn)折關(guān)系。14C固定搭配make a mistake意為“犯了個錯誤”。15B“我” 在喝完咖啡準(zhǔn)備離開時發(fā)現(xiàn)了自己的過錯，故應(yīng)選leave。.A本文講述了沉迷網(wǎng)絡(luò)游戲所引起的問題。16C詞義猜測題。diversion意為“轉(zhuǎn)移”，在文中意指人們通過虛擬世

29、界來逃避現(xiàn)實(shí)，故選C。17C推理判斷題。第二段通過三個年輕人的例子說明了網(wǎng)絡(luò)游戲?qū)δ贻p人的負(fù)面影響，故選C。18D推理判斷題。根據(jù)SueHuei Chen的研究，沉迷網(wǎng)絡(luò)游戲的人缺少友誼和人際交往，故可推斷增強(qiáng)個人的交往能力可以防止玩游戲上癮。19C細(xì)節(jié)理解題。根據(jù)第二段最后一句可知答案。20B主旨大意題。全文講述的是網(wǎng)游上癮的問題，故B項(xiàng)最符合文意。B這是一篇科普類文章。作者向我們報道了關(guān)于人腦信息和電腦信息研究的最新突破，該技術(shù)目前正準(zhǔn)備在病人身上應(yīng)用。21B細(xì)節(jié)理解題。由第一段可以看出，BCI技術(shù)是科學(xué)家一直研究的to link the brain with computers技術(shù)，由此

30、可知B項(xiàng)正確。C項(xiàng)有極大的干擾性。22D細(xì)節(jié)理解題。由第三段的In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.可知是說通過他的思維。故選D。23C事實(shí)排序題。由該段可知，信號從the scalp(頭皮)發(fā)出后被a special cap接收，接著傳到了a computer，然后到輪椅，由此可知C項(xiàng)正確。24B細(xì)節(jié)理解題。最后一段One is testing with real patients, so as to prove that this is a technology they can benefit from.中的they指的是patients，證明他們能從中獲益，也就是對于他們是有用的(useful)，因此可知答案。25C主旨大意題。 文章向我們介紹了瑞士BCI研究中心的一個新技術(shù)的工作原理，以及給殘疾人帶來的實(shí)惠。
