Do you agree with the writer? Give examples to support your opinion. And number 2, can you give examples of the risks of using avatars? What can you do to prevent such risks? When you are ready, share with your partners. OK, Who wants to share with us? Let's welcome. “(30’’79) Because most people create avatars that have similar features to their own and that look more or less like them and act like them. So I agree with the author. When I surf the Internet, I tend to create an avatar which is similar to myself in reality, even if there are slight differences between me and the avatar I created, the features, mostly with bright colors and happy faces are outgoing and interesting just like me. (31’’72) Using avatars might lead to online frauds. For example, you go to a blind date and discover that the person you meet doesn't look like his/her avatar at all. Worse still, some may even fall for a cute avatar and transfer money to strangers easily. To prevent such things from happening, I tend to chat with people I know in real life online only. Also, I would be very cautious if the online activity involves any transaction behavior.” Thank you for sharing! Good points! Avatars represent us in virtual worlds, so it more or less says something about us including our personalities. Sometimes the avatar is totally different from your real self. That means you want a change for yourself. Anyway, your avatar can show something about you. And it’s true that there are risks. Others may misuse our avatars for something bad or illegal. We can never be cautious enough! 1. When the technology of avatars first appeared in computer games in the 1980s, did people expect it to be widely used and developed?

Let's try to analyse the first sentence. X present future past X X X Past Future It expresses the idea that in the past you thought or predicted that something would happen in the future. 表示从过去某时看将来要发生的动作或存在的状态 As we can see, both “Xs” are in the past. The first X refers to the past simple time. The second X is positioned after the first one, which clearly is a future time for the first X. So it refers to the past future time. It shows that at this particular point in the past, we thought or predicted that something would happen at this point or here, or here or even in the far far future.. Got it? Excellent! Now let's take a look at the forms. would should was/were going to past predictions for the future 过去打算、计划做某事 或客观迹象表明要发生的事情 would 用于所有人称，should 只用在第一人称 表示过去计划或安排将要做某事，如果计划没有实现，不定式用完成时 表示过去正要/即将做某事，不与表示将来的时间状语连用 was/were about to do was/were to do As we can see, both “would” and “was were going to” can express the meaning of“past predictions for the future”. “Would” can express three other meanings, too. Namely, “pure future facts, promises made in the past , past willingnesses for the future”. “was/were going to” can also express another meaning—”past plans for the future”. Are you clear now? Good, now let's do some practice. 一、would 用于所有人称，should 只用在第一人称 She told us that she would not go with us, if it rained. 她告诉我们,如果下雨的话她就不和我们一起去了。 I telephoned him yesterday to ask what I should do next week. 我昨天给他打电话问我下周做什么。 二、was/were going to过去打算、计划做某事或客观迹象表明要发生的事情 I thought it was going to rain because the sky was very dark. 我想是要下雨了,因为天色很暗。 提示："would +动词原形"也可表示过去经常性、习惯性的动作。 When I was small, my mum would read me stories at night. 三、was/were about to do 表示过去正要/即将做某事，不与表示将来的时间状语连用。 When I got there they were about to leave.我到那儿的时候他们正要离开。 提示：Sb. be about to do...when..."句型表示"某人正要做某事,突然……"。 I was about to leave when someone knocked at the door.我正要离开,突然有人敲门。 四、was/were to do 表示过去计划或安排将要做某事 He said he was to finish the work in a week. 五、was/were doing 表示过去将来时，仅限趋向性动词，如go，come，leave，start，take off等。 $$
