A B Present future tense Now let’s read more examples. Something will happen in the future from a present point of view. Into the text 探究课文 Past Future 过去将来时 We use the past future to talk about what will happen in the future from the point of some time in the past. 一般会有一个发生在过去的动作，而过去将来时的动作要以此过去动作为参照点，在这个动作之后，将要发生的动作即可用过去将来时。 Eg. Very few people knew that future avatars would have such a wide variety of forms and uses. (很少有人知道未来的虚拟形象会有如此广泛的形式和用途。) 分析：“knew”已经是一个过去的动作，而 “would have” 这个动作若是以knew为参照物的话，又发生在knew之后，所以用过去将来时。 2. They discovered that they were going to have the power to create new identities. (他们发现他们将有能力创设新的身份。) 分析： “discovered”已经是一个过去的动作，而 “were going to have” 这个动作若是以discovered为参照物的话，又发生在其之后，所以用过去将来时。 Read the sentences. Write P below the underlined parts that refer to the past and PF below the underlined parts that refer to the future in the past. Yet, very few people knew that future avatars would have such a wide variety of forms and uses. 2. When people started creating their own avatars, they discovered that they were going to have the power to create new identities that did not look or act like real selves at all. 3. Many Internet users realised that their avatars would be seen by many people, not just their friends.
