雅思閱讀速度慢的6大成因及應(yīng)對策略

1.沒有良好的閱讀習(xí)慣

隨著網(wǎng)絡(luò)的發(fā)展，信息進(jìn)入爆炸發(fā)展的時(shí)代，人們對信息的攝入顯得越來越浮躁，現(xiàn)在的人們對于閱讀材料一旦字?jǐn)?shù)超過140 就很難堅(jiān)持讀下去(這也是微博字?jǐn)?shù)限制140的原因)，相信很多同學(xué)讀到這個(gè)位置的時(shí)候已經(jīng)忍不住想關(guān)掉退出了，心想“mark一下回頭再看吧!”

但是雅思閱讀文章都是700-1000字不等的文章，在閱讀中容易出現(xiàn)走神的現(xiàn)象耽誤時(shí)間。

解決方案：每天堅(jiān)持泛讀一篇完整的，1000字左右的英文材料，BBC news就是個(gè)不錯(cuò)的選擇。

2.英語語言基礎(chǔ)薄弱

詞匯&語法基礎(chǔ)薄弱，閱讀過程中生詞太多，或是長難句難以抓住句子主干，不能了解中心思想，導(dǎo)致反復(fù)閱讀及猜想，耽誤了時(shí)間。

解決方案：通過精讀雅思閱讀文章的方式積累單詞，辨析長難句鞏固語法。為自己定下目標(biāo)，每天至少通過精讀的方式記住比如50個(gè)生詞(根據(jù)自身情況而定)，至少一個(gè)以前不會(huì)的語法點(diǎn)。

3.短時(shí)記憶力差

看完題之后回到原文中掃讀文章找出題點(diǎn)，結(jié)果找的過程中忘了題目說的是什么而讀漏了，再翻過去看題，來回翻來回找，浪費(fèi)了時(shí)間。

解決方案：循序漸進(jìn)鍛煉短時(shí)記憶力，從1道題開始，讀完閉上眼，腦中重復(fù)2次該題內(nèi)容。回到原文中每讀完一小段馬上再重復(fù)回憶題目內(nèi)容。能夠無障礙記憶一道題之后，同時(shí)記憶兩道題再掃讀原文。以此類推。

生活中也可以時(shí)刻鍛煉短時(shí)記憶能力，比如說朋友的電話號碼，走在街上看到瞬間開過的車牌照，等等等都可以加強(qiáng)你的短時(shí)記憶能力，這個(gè)是可以靠短期的訓(xùn)練來提高的。

4.患有注意力缺失癥

患有注意力缺失癥的話，會(huì)很難堅(jiān)持一句一句的掃讀原文，大腦會(huì)帶著眼睛在文章里亂掃，浪費(fèi)了時(shí)間卻完全沒走心。

解決方案：可以自行百度“舒爾特表”來進(jìn)行練習(xí)集中注意力。畫一個(gè)5X5的表格，1寫到正中間，其他2-25亂序隨機(jī)寫到其他空格，練習(xí)時(shí)眼睛盯著中間的1，用旁光去按順序搜索2-25。

5.對雅思閱讀考試不了解

沒有參加過雅思培訓(xùn)，不了解考官出題模式，不了解雅思閱讀文章寫作規(guī)律，還在用原始的“先看文章再看題作答”的模式，或是在用精讀原文每一句話的強(qiáng)迫癥閱讀方式，導(dǎo)致時(shí)間不夠。沒有在考場上正確的合理的分配閱讀和解題的時(shí)間

解決方案：反復(fù)計(jì)時(shí)刷題、來聽孟老師的雅思閱讀課程。

6.瞎

這個(gè)老師幫不到你，千萬不要放棄治療。

以上這些提升雅思閱讀解題速度的方法適用于還有一定準(zhǔn)備時(shí)間的同學(xué)，閱讀速度不是一朝一夕就能有效提升的，要靠慢慢的積累，綜合能力的加強(qiáng)。

如果馬上就要考試的同學(xué)，短時(shí)間內(nèi)能做的就是練習(xí)合理的安排答題時(shí)間，記住一點(diǎn)：咱的目標(biāo)不是讀完三篇文章，而是做完40道題，其實(shí)也不是做完40道題，而是把30道題做對拿7分以上。讀完三篇文章和做對30道題是截然不同的概念。所以短期備考的同學(xué)要學(xué)會(huì)取舍。如果你的目標(biāo)是7分，你可以錯(cuò)10道題呢，一篇文章才13道題，相當(dāng)于可以放棄將近一整片文章。所以考試不怕錯(cuò)，只要你能快點(diǎn)錯(cuò)，抓緊時(shí)間錯(cuò)就好，把寶貴的時(shí)間留給真正能做出的題才是王道。

雅思閱讀機(jī)經(jīng)真題解析--Sunny Days For Silicon

Sunny Days For Silicon

You should spend about 20 minutes on Question 14-26 which are based on Reading Passage below.

AThe old saw that "the devil is in the details" characterizes the kind of needling obstacles that prevent an innovative concept from becoming a working technology. It also often describes the type of problems that must be overcome to shave cost from the resulting product so that people will buy it. Emanuel Sachs of the Massachusetts Institute of Technology has struggled with many such little devils m his career-tong endeavor to develop low-cost, high-efficiency solar cells. In his latest effort, Sachs has found incremental ways to boost the amount of electricity that common photovoltaics (PVs) generate from sunlight without increasing the costs. Specifically, he has raised the conversion efficiency of test cells made from multi-crystalline silicon from the typical 15.5 percent to nearly 20 percent—on par with pricier single-crystal silicon cells. Such improvements could bring the cost of PV power down from the current $1.90 to $2.10 per watt to $1.65 per watt. With additional tweaks, Sachs anticipates creating within Four years solar cells that can produce juice at a dollar per watt, a feat that would make electricity (rum the sun competitive with that from coal-burning power plants.

BMost PV cells, such as those on home rooftops, rely on silicon to convert sunlight into electric current. Metal interconnects then funnel the electricity out from the silicon to power devices or to feed an electrical grid. Since solar cells became practical and affordable three decades ago, engineers have mostly favored using single-crystal silicon as the active material, says Michael Rogol, managing director of Germany- based Photon Consulting. Wafers of the substance are typically sawed from an ingot consisting of one large crystal that has been pulled like taffy out of a vat of molten silicon. Especially at first, the high-purity ingots were left over from integrated-circuit manufacture, but later the process was used to make PV cells themselves, Rogol recounts. Although single-crystal cells offer high conversion efficiencies, they are expensive to make. The alternatives- multi-crystalline silicon cells, which factories fabricate from lower-purity, cast ingots composed or many smaller crystals—arc cheaper to make, but unfortunately they arc Jess efficient than single-crystal cells.

CSachs, who has pioneered several novel ways to make silicon solar cells less costly and more effective, recently turned his focus to the details of multi-crystalline silicon cell manufacture. The first small improvement concerns the little silver fingers that gather electric current from the surface of the bulk silicon," he explains. In conventional fabrication processes, cell manufacturers use screen-printing techniques ("like high-accuracy silk-screening of T-shirts," Sachs notes) and inks containing, silver particles to create these bus wires. The trouble is that standard silver wires come out wide and short, about 120 by 10 microns, and include many nonconductive voids. As a result, they block considerable sunlight and do not carry as much current as they should.

DAt his start-up company—Lexington, Mass- based 1366 Technologies (the number refers to the flux of sunlight that strikes the earth's outer atmosphere: 1.366 watts per square meter)—Sachs is employing "a proprietary wet process that can produce thinner and taller" wires that are 20 by 20 microns. The slimmer bus wires use less costly silver und can be placed closer together so they can draw more current from the neighboring active material, through which free electrons can travel only so far. At the same time, the wires block less incoming light than their standard counterparts.

EThe second innovation alters the wide, flat interconnect wires that collect current from the silver bus wires and electrically link adjacent cells. Interconnect wires at the top can shade as much as 5 percent of the area of a cell. "We place textured mirror surfaces on the faces of these rolled wires. These little mirrors reflect incoming light at a lower angle--around 30 degrees-—so that when the reflected rays hit the glass layer at Lire top, they stay within the silicon wafer by way of total internal reflection,” Sachs explains. (Divers and snorkelers commonly see this optical effect when they view water surfaces from below.) The longer that light remains inside, the more chance it has to be absorbed and transformed into electricity.

FSachs expects that new antireflection coatings will further raise multi-crystal line cell efficiencies. One of his firm's future goals will be a switch from expensive silver bus wires to cheaper copper ones. And he has a few ideas regarding how to successfully make the substitution. "Unlike silver, copper poisons the performance of silicon PVs," Sachs says, "so it will be crucial to include a low-cost diffusion barrier that stops direct contact between copper and the silicon." In this business, it's always the little devilish details that count.

GThe cost of silicon solar cells is likely to fall as bulk silicon prices drop, according to the U.S. Energy information Administration and the industry tracking firm Solarbuzz. A steep rise in solar panel sales in recent years had led to a global shortage of silicon because production capacity for the active material lagged behind, but now new silicon manufacturing plants are coming online. The reduced materials costs and resulting lower system prices will greatly boost demand for solar-electric technology, according to market watcher Michael Rogol of Photon Consulting.

太陽能硅電池

A

古語“細(xì)節(jié)決定成敗”形象地刻畫出了了那種針尖大小的障礙足以阻止一個(gè)創(chuàng)新的概念轉(zhuǎn)化成一項(xiàng)實(shí)用的技術(shù)。它往往也描述出了這樣一類問題：通過降低產(chǎn)品的成本來吸引消費(fèi)者來購買。麻省理工學(xué)院的Emanuel Sachs在他的職業(yè)生涯中一直在努力通過許多這樣的小細(xì)節(jié)開發(fā)低成本且高效率的太陽能電池。在他最新的研究中，Emanuel Sachs己經(jīng)發(fā)現(xiàn)許多在不增加成本的前提下提高普通光伏（PV）從太陽光中產(chǎn)生的電量。具體來說，他將由多結(jié)晶硅制成的測試電池的轉(zhuǎn)換效率從典型的15.5%提高至近20%——達(dá)到了比其價(jià)格更高的單晶硅電池的轉(zhuǎn)換效率。這種改進(jìn)可能將光伏發(fā)電的成本由現(xiàn)在的$1.90到$2.10每瓦下跌到$1.65每瓦。隨著更多的調(diào)整，Sachs預(yù)計(jì)在四年內(nèi)發(fā)明出太陽能電池，他可以講成本降到$1每瓦，這將使轉(zhuǎn)化自太陽能的電力由燃煤電廠生產(chǎn)的電力形成競爭關(guān)系。

B

大多數(shù)光伏電池，比如那些在家里的屋頂，是依靠硅材料將太陽光轉(zhuǎn)換成電流。金屬互相連接將電流從硅中導(dǎo)出來向電網(wǎng)輸電。德國Photon Consulting公司常務(wù)董事Michael Rogol，認(rèn)為自太陽能電池在30年前被普遍推廣使用起，工程師們大多是釆用單晶硅作為活性物質(zhì)的。該物質(zhì)的晶片通常是從由一大塊晶體組成的錠上鋸下來的，而該晶體是從一大桶熔化了的硅中像太妃糖似得被拔出來的。Rogol補(bǔ)充說，特別是在剛開始的時(shí)候，髙純度硅錠被廢棄在集成電路制造廠，但之后就被用來制造太陽能電池。雖然單晶電池能提供商的轉(zhuǎn)換效率，但它們的生產(chǎn)成本很高。其替代品——多晶硅電池，是工廠用低純度的由許多小的晶體組成的鑄造錠中制造的，生產(chǎn)成本低廉，但不幸的是他們比單晶電池的轉(zhuǎn)換效率要低。

C

Sachs率先推出了一些新的方法使得太陽能硅電池更便宜更有效，最近他又將重點(diǎn)放在多晶硅電池制造的細(xì)節(jié)上。他解釋說，第一個(gè)需要小幅改進(jìn)的問題是關(guān)于“收集電流從硅表面上匯集電流的小的銀制線路”。在傳統(tǒng)的制造工藝中，電池制造商使用絲網(wǎng)印刷技術(shù)（“就像像高精度絲網(wǎng)印刷T恤一樣，”Sachs注）和含有銀粒子的油墨來創(chuàng)建線路。麻煩的是，標(biāo)準(zhǔn)的銀制電線一般寬而且短，大約120微米長10微米寬，并包含許多不導(dǎo)電的空隙，因此阻擋了大量的陽光的吸收從而減少了本該傳輸?shù)碾娏餍恰?/p>

D

在他創(chuàng)辦的第一家位于馬薩諸塞州Lexington的Technologies公司（該數(shù)字意指太陽光撞擊地球外層大氣的流量是：每平方米1366瓦特）——Sachs采用一項(xiàng)專有技術(shù)來制造更薄更高的電線：20.0微米。這種更細(xì)的電線使用成本較低的銀，并且可以放置得更近，使它們能夠從鄰近的活性物質(zhì)吸引更多的電流，在這些活性物質(zhì)中，自由電子只可以在有限的范圍內(nèi)移動(dòng)。與此同時(shí)，該電線比其它對應(yīng)電線阻擋較少的入射光。

E

他的第二項(xiàng)創(chuàng)新改變了用來收集從銀制電線以及電氣連接的相鄰的電池中的電流的扁平較寬的互相交錯(cuò)的電線。位于頂部的互相交錯(cuò)的電線可遮擋一個(gè)電池多達(dá)5%的區(qū)域。Sachs解釋道，“我們在這些軋線的表面放上質(zhì)感的鏡面。這些小反射鏡在一個(gè)較低的角度——大約30度左右反射入射光。因此，當(dāng)反射光線擊中頂部的玻璃層時(shí)，它們將會(huì)通過全內(nèi)反射的方式留在硅晶片內(nèi)?！保ó?dāng)潛水和浮潛的人從水下面看水的表而時(shí)，通常會(huì)看到這種光學(xué)效應(yīng)。）該光線在硅晶片中停留的時(shí)間越長，它越有機(jī)會(huì)被吸收且被轉(zhuǎn)化成電能。

F

Sachs預(yù)計(jì)新的抗反射涂層將進(jìn)一步提高多晶電池的效率。他公司的未來目標(biāo)之一是用較便宜的銅制電線替代目前使用的價(jià)格昂貴的銀制電線。他對于如何成功地完成這項(xiàng)轉(zhuǎn)換已經(jīng)有了一些想法。Sachs說“銅不像銀，它會(huì)削弱硅光伏電池的性能，所以使用阻斷銅與硅之間的直接接觸的材料將是至關(guān)重要的?！痹谶@個(gè)行業(yè)，往往是細(xì)節(jié)決定成敗?！?/p>

G

美國能源信息署和行業(yè)跟蹤公司Solarbuzz認(rèn)為，太陽能硅電池的成本很可能會(huì)隨著硅價(jià)格的下降而走低。最近幾年太陽能電池板銷售的陡然上升己經(jīng)導(dǎo)致硅的全球性短缺，因?yàn)榛钚晕镔|(zhì)的產(chǎn)能落后，但是現(xiàn)在新的硅制造工廠即將上線。Photon Consulting公司的市場觀察員Michael Rogol認(rèn)為，降低的材料成本以及隨之降低的價(jià)格大大提高提振太陽能光電技術(shù)的需求。
