4. paragraph 6 ___.
Nanotechnology engineers try to mimic nature, building things atom-by-atom. Among other things, nanomotors could be used in optical circuits to redirect light, a process called optical switching. Futurists (未來主義者)envision(想象) a day when nanomachines, powered(被供以動(dòng)力) by nanomotors, travel(旅行) inside your body to find disease (疾?。゛nd repair(修復(fù)) damaged(受損的) cells(細(xì)胞).
4. F Nanomotors是段落主題詞,關(guān)注多次涉及段落主題詞的段尾句內(nèi)容與F一致。 因此F是答案。 從內(nèi)容上看:第六段預(yù)想了納米發(fā)動(dòng)機(jī)的用途,如用于光電路以改變光的方向 (redirect light) 和驅(qū)動(dòng)納米機(jī)器進(jìn)入人體,消滅病灶。選項(xiàng) F “Possible fields of application in the future” 概括了本段的大意。
A. remove(去除, 移動(dòng)) disease(疾?。?BR> B. resist separating考試大論壇
C. shuffle between two molten metal droplets
D. power nanomachine來源:考試大
E. sop up molecules from the large droplet
F. transport nanoscale objects考試大論壇
被選項(xiàng)語法結(jié)構(gòu)特征一致, 都是動(dòng)詞短語結(jié)構(gòu)。
5.Doctors(醫(yī)生) envision(幻想) that the nanomotor(納米發(fā)動(dòng)機(jī)) would travel through(穿越) human bodies to __________ .
5.答案是 A。題干出現(xiàn) doctors envision,選項(xiàng)的內(nèi)容應(yīng)與醫(yī)學(xué)有關(guān),選項(xiàng) A 是 remove disease, 正好與題干的內(nèi)容相配,是答案。也可利用問題句中的細(xì)節(jié)信息詞doctor作為答案線索, 在文章中查找答案相關(guān)句:
(第一段)One day a similar(相似的) engine(發(fā)動(dòng)機(jī)) might power(給...提供動(dòng)力) a tiny(微小的) mechanical(機(jī)械的) doctor that would travel through your body to remove your disease.
B. resist(反抗) separating(分開)
C. shuffle between two molten metal droplets
D. power nanomachine
E. sop up molecules from the large droplet
F. transport nanoscale objects
6.Surface tension (表面張力)means(意味著) the tendency(傾向/趨勢) of atoms(原子) or molecules (分子)to __________
6. B 利用問題句中的細(xì)節(jié)信息詞(surface tension)作為答案線索, 在第三段第一句找到答案相關(guān)句: “surface tension -- the tendency of atoms or molecules to resist(抗拒, 反抗) separating(分開)-- becomes more important(重要的) at small scales(級別)”。
C. shuffle between two molten metal droplets
D. power nanomachine來源:考試大網(wǎng)
E. sop up molecules from the large droplet
F. transport(運(yùn)輸) nanoscale(納米等級的) objects(物品, 東西)
7.Nanoconveyors(納米傳送帶) could be used to(被用于) __________ .
7.F 題干的 nanoconveyor 提示我們,納米傳送帶的功能自然是傳送納米等級的物體,所以F 是答案。也可以利用問題句中的細(xì)節(jié)信息詞(nanoconveyors)作為答案線索,找到答案相關(guān)句:In 2006, they built a nanoconveyor, which moves(移動(dòng)) tiny(微小的) particles(粒子) along( 往前) like(象) cars in a factory(工廠). F是定語從句的概括句。
C. shuffle(來回移動(dòng)) between two molten metal droplets
D. power nanomachinehttp://ks.examda.com
E. sop up(吸收) molecules from the large droplet
8.Applying(應(yīng)用, 申請, 施加) a small electric current (電流)causes(造成) atoms(原子) to __________ .
8.C 利用題干的細(xì)節(jié)信息結(jié)構(gòu)a small electric current作為答案線索, 在文章中找到答案相關(guān)句。
When a small electric current is applied to (被施加到)the droplets(小滴), atoms(原子) slowly get out of (從...出來)the larger(更大的) droplet and join(加入) the smaller one. The small droplet grows(增大) – but never gets as big as (與...一樣大)the other droplet – and eventually(最終) bumps into (撞擊)the large droplet. As they touch(接觸), the large droplet rapidly(迅速地) sops up(吸收) the atoms(原子) it had previously(以前) lost(失去). This quick shift in (變化) energy(能量) //produces(產(chǎn)生) a power stroke(動(dòng)力形成). E是對該段內(nèi)容的概括
