Being Left-handed in a Right-handed World

The world is designed for right-handed people, but why does a tenth of the population prefer the left? 71

The answer to it remains a bit of a mystery. Since scientists have noticed left-handedness tends to run in families, it’s assumed that left-handedness has a genetic（基因的）component to it.72 In fact, identical twins, who share the same genes, can sometimes prefer to use different hands. There are also plenty of theories on what else might determine which hand you write with,but many experts believe that it’s kind of random.

Historically, the left side and left-handedness have been considered a negative thing by many cultures.

73 In some areas, the left hand became known as the “unclean” hand. In many religions, the right hand of God is the favored hand. For example, Jesus sits at God’s right side.God’s left hand, however, is the hand of judgment. Various activities and expressions become rude or even signs of bad luck when the left hand becomes involved. In some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a journey. 74 A person giving directions will put left hand behind them and even physically try to point with their right hand if necessary. In some Asian countries, eating with the left hand is considered impolite,

75 People come to realize that left-handedness is natural. People even noticed that many famous people

are left-handed, including Benjamin Franklin, Leonardo Da Vinci, and Charlie Chaplin. Some researchers find out that lefties are more creative and can deal with abstract thinking better. The left-handedness is more easily adaptable to the right-handed world as well. Being left-handed is no longer a sad story now: instead, it is a wonderful gift or maybe it is something you should take pride in.

A. In other words, left-handers are born that way.

B. Left-handedness are used to be regarded as a disability.

C. The unfavorable associations of the use of the left hand among cultures are varied.

D. Why do they prefer to use their left hand rather than their right hand for routine activities?

E. Why do some parents force their left-handed children to become right-handed when writing?

F. In Ghana, pointing, gesturing, giving or receiving items with the left hand is considered rude.

G. Fortunately, nowadays most societies and cultures no longer reject left-handedness like before.

逐题分析

语篇解读：本文为说明文。文章介绍了“左撇子”在人文社会中的处境。

1.解析：本题考察的是并列关系。空格前是why引导的一个疑问句，选项D在句式和话题上保持一致。另外，第二段开头the answer to it, 与上段问句相呼应。因此选D

答案：D

2.解析：本题考察的是解释例证关系。空格前大意为左撇子与遗传基因有关系，而空格处是对这句的解释例证关系，选项A中关键词in other words，因此选A

答案：A

3.解析：本题考察的是同范畴词。空格前大意为：左撇子在历史上被认为是不好的事情。C选项中unfavorable 与negative属于同范畴词。空格后的讲的都是不同文化地区对左撇子的不认同。因此选C

答案：C

4.解析：本题考察的是并列关系。本段主要是不同地区对左撇子的不认同，如：in some areas，in many religions，in some parts of Scotland，in some Asian countries，因此空格处与这些词形成并列关系，另外内容上与空格后保持一致。

答案：F

5.解析：本题考察的是段首主题句。空格位于句首，空格后讲的都是对左撇子态度的改变，通过more creative，gift，take pride in等可以判断。选项G中关键词no longer reject left-handedness，因此可以作为本段主旨句。

答案：G

阅读练习

The average computer user has between 5 and 15 username/password combinations to log in different kinds of accounts. Some demand you use a specific number of symbols and digits, while others require you to change your password every 60 days. The feeling of confusion resulting from memorizing these login information has grown so common that it actually has a name: password fatigue(疲劳).

Having to remember so many different passwords is annoying, but it can also be dangerous. Because it is virtually impossible to remember a unique password for each of these accounts, many people leave handwritten lists of usernames and passwords on or next to their computers.

71 While these practices make it easier to remember login information, they also make it easier for thieves to hack into accounts.

Single Sign-On (SSO) confirmation and password management software can help solve this problem. With SSO, users only need to remember one password to log in to the main system. 72 SSO software is typically used by large companies, schools, or libraries.

73 If a user loses or forgets the password required to log in to SSO software, the user will then lose access to all of the applications linked to the SSO account. Users who rely on password management software face the same problems.

Although most websites or network systems allow users to recover or change lost passwords by providing email addresses or answering a prompt（提示）, this process can waste time and cause further frustration. What is more, recovering a forgotten password is only a temporary solution.74

Some computer scientists have suggested computers rely on biometrics(生物测定学). 75 The use of biometrics raises questions concerning privacy and can also be expensive to practice.

Software engineers and computer security experts are still searching for the cure to password fatigue. Until they find the perfect solution, however, everyone will simply have to rely on the password system currently in place.

A. It does not address the larger problem of password fatigue.

B. These software programs have been built into many major web browsers

C. The problem with password management software makes users feel powerless.

D. The SSO software then automatically logs the user in to other accounts within the system.

E. However, SSO confirmation and password management software also have drawbacks.

F. This is a method of recognizing human users based on unique traits, such as fingerprints, voice, or DNA.

G. Others solve this problem by using the same password for every account or using extremely simple passwords.
