Ananova — the World’s First Virtual Newscaster

Hello, my name is Ananova and I am the world’s first virtual newscaster. I live in cyberspace. I work in front of a very fine computer system with much information. My job is to scour the web and bring information to you. You can get this information through something like a desktop or a mobile phone.

On April 19, 2000 I read news on the Internet for the first time. My creators spent a year developing me. They studied hundreds of photos of ordinary and famous people’s faces to come up with my unique looks. My green hair makes me look different from real human. Then they worked with digital animation specialists, created my 3D head and body and made me move. The text-to-speech system creates my voice. At the same time the live animation technology matches my mouth movements to my words.

And here I am! You can see and hear me at my website 24 hours a day, 7 days a week. You can e-mail from there as well. I love to know you.

Computer Mouse

Douglas Engelbartinvented a number of information access systems. In 1968 he invented the computer mouse. It helps popularize the use of computers.

The mouse is an important part of a computer. It is a casing with a flat bottom. It has one or a few buttons on the top. On the bottom is a ball and it is a device to detect directions. A cable connects the mouse to a computer. First, the user holds the mouse with one hand, moves it on a surface like a desk. In this way the user controls the cursor on the screen. And then he or she presses one of its buttons and makes a “mouse click”.

Douglas Engelbart finished a lot of design work in the computer world. The mouse was only one of his inventions.

语法要点

I. 句子的分类

句子按结构可分为简单句、并列句和复合句。其具体类别及用法如下表所示:

类别

简单句

并列句

复合句

定义

一个句子只包含一个主谓结构,而句子各个成分都只由单词或短语表示,它就是简单句;有时一个句子有两个(或两个以上)并列的主语或谓语,也仍是简单句。

一个句子包含两个或更多的互不依从的主谓结构,就是并列句。并列的各个部分(即各个主谓结构)称为分句。各个分句用并列连词(如 and, or 等)连接;在上下文紧密联系的情况下也可以不用连词,而以逗号隔开。

一个句子中,有两个或更多的主谓结构,其中有一个(或更多的)主谓结构充当句子的某一(些)成分,如主语、宾语、表语、定语、状语、同位语等,就是复合句。作为一个句子成分的主谓结构称为从句。按照句法作用的不同,从句又分为主语从句、宾语从句、定语从句、状语从句、表语从句等。

举例

My job is to scour the web and bring information to people.(我的工作是搜索网路,再将信息带给人们。)

He is a doctor and works hard. (他是个医生,工作很努力。)

Zhang Lin and I often chat on the net.(张林盒我经常网上聊天。)

My name is Anna and I am a newscaster.(我叫安娜,是新闻播报员。)

Some of them are from the south while others are natives. (他们中有些人来自南方,其他人是本地人。)

They were very tired, but they finish their work on time. (他们很累,但还是按时完成了工作。)

I hope that everyone is happy. (我希望大家开心。)(从句作宾语)

Jack was a shop assistant before he was 20. (20岁以前,杰克是营业员。)(从句作状语)

II. 状语从句

英语中带状语从句的复合句很多。状语从句有的表示时间,有的表示原因、条件等,因此也可以分为时间状语从句、条件状语从句、原因状语从句等。本书所介绍的状语从句如下表所示:

类别

举例

时间状语从句

He took a walk after he had dinner. (他吃了饭后去散步。)

原因状语从句

Because this book is very interesting, children like reading it. (因为这本书很有趣味性,所以孩子们都爱读。)

结果状语从句

He is always busy, so he rarely goes home. (他总是很忙,很少回家。)

条件状语从句

If I meet him, I’ll give him an umbrella. (如果我见到他,就会给他一把伞。)

状语从句通常由从属连词(如 when,because,so,after 等)引起。由这类词引起的主谓结构不能成为独立的句子,只能作状语从句。在使用状语从句时应注意:

1. 状语从句本身结构必须完整,不能没有主语。例如:

He was in Shanghai before he came here.(他来这里以前在上海。)

Come here when you have time.(有空请过来。)

2. 状语从句如在主句前,一般用逗号将它与主句隔开;如在主句的后面,可不必用逗号。例如:

When we got there, it was 9 o’clock. 或 It was 9 o’clock when we got there. (我们到那里时已经9点了。)
