Most people are right-handed．This fact also seems to have held true （26）throughouthistory．In 1977，scientists studied works of art made at various times starting with cave drawings from 15，000B．C．a(chǎn)nd ending with paintings from the 1950s．Most of the people（27）shown/showed（show） in these works of art are right-handed．
Many researchers claim （28）to have found（find）relationships between left-handedness and various physical and mental characteristics．However（29）someof these connections are very weak，and others have not been proven．What makes a person become right-handed rather than left-handed？As yet，no one really knows for sure．（30）No matter whatreasons may be behind it，people's attitudes toward left-handedness have changed a lot over the years．There are even a number of shops（31）specializing（specialize） in selling products for left-handed people，such as left-handed scissors，can openers，guitars，and even a left-handed camera．In 1976，Left-Handers International，a group of left-handed people in Topeka，Kansas，in the United States，decided to start （32）anannual event in order to clear up misunderstandings about left-handedness．

Answer 1

分析 列奧納多，瑪麗居里和艾伯特愛(ài)因斯坦有共同之處，他們都是左撇子，世界上百分之13的人口可能是左撇子．

解答 25．may/can   考查情態(tài)動(dòng)詞    根據(jù)前文的estimated可知，這個(gè)數(shù)據(jù)不是非常確定，所以用may/can．
26．throughout 考查介詞  throughout history 縱觀歷史，在整個(gè)歷史上．
27．shown/showed 考查分詞作后置定語(yǔ)，the people與show之間是邏輯上的動(dòng)賓關(guān)系，所以用過(guò)去分詞短語(yǔ)作后置定語(yǔ)．
28．to have found 考查動(dòng)詞用法   claim to have done sth．聲稱做過(guò)某事．
29．some 考查代詞 some…others…是習(xí)慣性的搭配，意思是"一些…另一些…"
30．No matter what 考查讓步狀語(yǔ)從句，no matter what引導(dǎo)讓步狀語(yǔ)從句，句意為"不管背后的原因是什么，這些年來(lái)人們對(duì)左撇子的態(tài)度已經(jīng)變了很多．"
31．specializing 考查分詞，shops與specialize之間是邏輯上的主謂關(guān)系，所以用現(xiàn)在分詞．
32．a(chǎn)n?考查冠詞，此處是泛指一次年度性的活動(dòng)，所以用不定冠詞，annual以元音開(kāi)頭，所以用an．

點(diǎn)評(píng) 缺詞填空，解題時(shí)要抓住文章的脈絡(luò)，一定要讀懂全文，弄清文章要表達(dá)的思想，注意前后句之間的關(guān)系．答題中，一定要認(rèn)真分析，注意詞性，句型的分析，答完后再通讀一遍文章，看看所填單詞是不是語(yǔ)句通順，語(yǔ)意連貫．
