Ⅱ.阅读理解

A

Most people watching Jeremy Lin these past two months saw Jeremy Lin，New York Knicks star；but I，watching him，saw someone else.That was my elder brother，Bob，who is athletic and energetic.He could never sit still when he was in second grade；he had to get up every now and then and run around the room.And sure enough，he grew up to be a starting player for an NCAA championship lacrosse (长曲棍球) team.He was a Nike­endorsed marathoner，too，and reached the top of Mt.Everest，unguided，in his 50s.

And yet my family never watched his lacrosse games.We did watch some of his marathons，but that wasn't until he was in his 20s.When Bob was in his glory days，our Shanghainese­born parents were bent on getting him into medical school.There was a loving aspect to it：I can remember my father working through math books with him，lesson by lesson，at the big blackboard in the attic.Bob never did become a doctor，though；and neither did I．It wasn't until my younger sister came along that someone in the family finally wore a white coat.

Bob today could be the fittest 58­year­old on the planet.His doctor estimates his biological age at 35；he's still big mountains in the Himalayas.And，like Jeremy Lin，he's charming.No one sees Bob without leaving with a laugh.He sometimes jokes he could be mayor of his building，and it's true.To know him is to cheer for him.

And yet my parents did not cheer for him.What if my mother had sat on the sidelines with her statistics，like Jeremy Lin's mother？What if my father had played videos of athletes for my brother to watch and imitate？It's hard not to wonder.

And how did Jeremy Lin's parents manage to do these remarkable things？Amy Chua，the tiger mother，recalls her immigrant father beating the kids whenever they mispronounced a Chinese word.How is it that Jeremy Lin's immigrant father in particular，Gie­Ming Lin，encouraged his son to follow such an untraditional path?

A Japanese company has created a “smart” mask (口罩)that aims to improve communication for people wearing face coverings to prevent the spread of COVID­19.

The use of face masks has become the new common practice in parts of the world still struggling to reduce the spread of the coronavirus.However, masks and other kinds of coverings can affect the quality of communication between wearers.The wearable electronic device (设备) called the “c­mask” is meant to fit over other kinds of face masks commonly worn by the public.It's designed to better the exchange of conversation in such conditions.

The c­mask with a built­in microphone has holes in the front to let air in.When turned on, the mask uses Bluetooth technology to connect to a mobile device.An app then helps users do several actions, including turning speech into text, completing telephone calls and making the user's voice louder.The device can also translate a person's voice from Japanese into eight other languages.

Taisuke Ono, head of Donut Robotics, said the company was able to collect money to develop the smart mask through an activity on the Japanese crowdfunding (众筹)service Fundinno.He noted that the effort got $265，000 in just the first 37 minutes.It would usually take three or four months to collect that kind of money.

The company produced a working model of the mask within a month.Ono said the company plans to ship its first 5，000 c­masks to buyers in Japan.He is also looking to sell the devices in China, the United States and Europe and says he has received strong interest in the product.

How can we keep safe personal information on our computers or cell phones？  1 

View emails with a careful eye.

It's best to view all emails with care.Hackers (黑客) can make emails look like real company emails.  2   It's best to search for the original source of the information，and try to find the direct link from the site instead of using the link provided in the email.

Use two­factor authentication (双重认证)．

Two­factor authentication adds a second level of safety to an account.  3   It's a safety option that requires a password as well as an additional piece of information only the user would know.

Update apps and operating systems.

  4   While these updates may appear to only change the way your phone's software looks，they often come with safety improvements.There may be a bug (软件漏洞)．Those bugs are discovered by cell providers or smartphone makers，so it's a good idea to upgrade them.

  5   

It's no surprise that changing your password has always been a basic form of protection.But what we pick as passwords and how we manage them are important.First，passwords should never include your personal information.So stay away from names and birthdates.Ideally，passwords are a combination of lowercase (小写) and uppercase (大写) letters and random characters.It could be a strong，long password that doesn't have any personal information，making it harder to remember.

A．Manage passwords safety.

B．Here are some steps to make it.

C．It can trick readers into clicking on dangerous links.

D．Often users are unwilling to update their mobile devices.

E．Combine your personal information with random figures.

F．Here are some ways to create your online personal passwords.

G．Do it if there's an option for your email，banking site or social media site.

【语篇解读】　本文介绍了一些让你安全地把个人信息保存在电脑或手机上的方法。

2．C　[根据上文：黑客可以使邮件看起来像真正的公司电子邮件。下文：最好是搜索原始的信息来源，并尝试从网站上找到直接链接，而不是使用电子邮件中提供的链接。可知，它可以让读者点击进入危险链接。此处it指的是邮件，故选C。]

3．G　[根据上句：双重认证给账户增添双重保险，再根据空格下句：这是一个需要密码和一个只有用户才知道的信息的安全选项。可知，如果你的电子邮件、银行网站或社交媒体网站有该选项，那就这么做。故选G。]

4．D　[根据本段标题Update apps and operating systems和下文：虽然这些更新可能只会改变手机软件的外观，但它们通常会带来安全方面的改进，可知，通常用户不愿意升级他们的移动设备。故选D。]

5．A　[本空是小标题。根据本段第一句：更改密码一直是一种基本的保护方式，可知本段讲的是关于管理密码的安全，故选A。]
