Unit 3 Computers

Using apps to protect teens, kids online Most kids have cellphones or tablets (平板) and are texting or using

social media all the time. Experts say that parents should use apps to watch out for their children's online activities. According to a survey, 70 percent of US teens carry cellphones, and Russ Warner, the CEO of Net Nanny, is in the business of protecting kids online. His best advice to parents is to know what is out there and to plan in advance.

“Put a plan into place because kids like to feel protected ， ” Warner said. “They like to feel like Mom or Dad is helping.” According to another study, almost 90 percent of children have seen cyber bullying (网络欺凌) in the last year. However, Warner said only 50

percent of parents talk with kids about avoiding these experiences.

“That means the other half don't and that's a problem，” he said. Warner often speaks to parent groups concerned about keeping their teens safe, “Oftentimes (时常地) if we can't control or we don't

understand something, we avoid it and we can't do that anymore.”

He said parents need to talk to their children about online danger, and then they need to use safety software. Parents should know who is trying to communicate with their children and what they are watching online. Warner added parents also need to understand phone settings (设置).

iPhone settings come with restrictions (限制) that are easy to set. Parents

can enable restrictions with a code that they know, and their child does not. Parents can also set phones to not allow apps to be downloaded without a passcode.开户快乐学习之旅

课文预读

我是谁？

[第 1 段译文]

随着时间的推移我已经被改变了很多。1642 年我在法国诞生时

是一台计算机器。尽管当时我很年轻，但是我能简化一些复杂的数学

题。我发育缓慢，差不多到了两百年之后，查尔斯·巴比奇才把我制

成了一台分析机。在操作员用穿孔卡为我设计程序后，我能够进行逻

辑“思考”，并且能够比任何人更快地算出答案。那时这被当作一次

技术革命，也是我“人工智能”的开始。在 1936 年，我真正的父亲

艾伦·图灵写了一本书，讲述了怎样使我成为一台“通用机器”来解

决任何数学难题。从那时起，我在体积和脑容量方面迅速成长。到 20

世纪 40 年代，我已经长得像一间屋子那么大，我不知道我是否还会

长得更大。但是，这个现实也使得我的设计者很担心。随着时间的推

移，我被做得更小了。自 20 世纪 70 年代以来，我一直被用在办公室

和家庭里，先是用作个人电脑，后来又做成便携式电脑。

[第 2～3 段译文]

这些变化只有随着我的存储能力的不断提高才成为可能。最初是

被存储到电子管中，以后是晶体管上，后来是非常小的芯片上。因此，

我已经完全改变了我的形状。随着我的年龄越来越大，我也变得越来

越小。随着时间的推移，我的记忆能力发展得如此之快，就像一头大

象一样，我从来不会忘记告诉我的任何事情！我的存储容量变得如此

巨大，连我自己都不能相信！但是我总是孤孤单单地站在那里，直到

20 世纪 60 年代初，他们才给了我一个用网络连接的家庭。我能够通

过万维网和其他人分享我的知识。

从 20 世纪 70 年代起，我又被开发出了很多新的用途。我在通信、

金融和贸易领域变得非常重要。我还被放在机器人里面，被用来制作

移动电话，并且用来帮助做医疗手术。我甚至还被放置在航空火箭里

去探测月球和火星。不管怎样，我的目标是给人类提供高质量的生活。

现在我充满了幸福，因为我是人类忠实的朋友并时时给他们提供帮助！

Unit 3 Section Ⅱ

Ⅰ.单句语法填空

1．(重庆高考改编) In my hometown，there is always a harvest supper for the farmers after all

the wheat_has been cut__(cut)．

解析：考查动词的时态和语态。句意：在我的家乡，麦子丰收过后农民会有一个庆祝晚餐。现在完成时表示动作已经完成，才会举行庆祝活动，而且wheat与cut之间构成逻辑上的动宾关系，所以用被动语态。

2．—Is the meeting being held now?

—No.I hear that it_has been put__(put) off till tomorrow.

解析：考查动词的时态和语态。答语句意：我听说会议已推迟到明天了。put off“推迟”，与meeting之间为被动关系。会议现在已被推迟，故用现在完成时的被动语态。

3．All possible means_have been tried__(try) to protect this kind of animals in danger up to

now.

解析：考查时态、语态和主谓一致。由时间状语up to now可知应用现在完成时。另外，主语means与try之间为动宾关系，故用被动语态。means为单复数同形的单词，由其前的all可知此处作复数名词。

4．—Your English is very good.

—I'm still nervous.After all，it is only the second time that I_have met__(meet) foreign

guests.

解析：考查时态。该题考查“It is the＋序数词＋time＋that从句”这一句型中的时态，该句型中that从句的时态用现在完成时。

5．Many of her friends have_been invited__(invite) to her birthday party.
