There____ a book and two rulers on the desk. b. There ____ two rulers and a book on the desk. ③ There be 句型有时态的变化 a. 一般现在时：There is/are… b. 一般过去时：There was/were… c. 一般将来时：There will be… / There is/are going to be… ④there be句型的一般将来时 结构为：There will be + 主语+其他。其否定形式是在will 后加not；疑问句形式是把will 提到there前。简略肯定回答：Yes, there will. 简略否定回答：No, there won‘t. a.将没有足够的给人住的空间。________________________ . b.世界上将有更少的动吗? ? 3、自主探究 (1)Do you think there will be robots in people‘s homes？ 此句是一含宾语从句的主从复合句，Do you think…是主句，there will be…是宾语从句。Do you think…?答语一般为：Yes, I think so.或No, I don‘t think so.有时do you think作为插入语，放在特殊疑问词后，该疑问句的其他部分应为陈述语气。 a.你认为十年后你会干什么？________________________________? b.I think:我认为每家都会有个机器人。________________________ c.I don‘t think:我认为将来孩子们不会去上学。_______ （2）fewer, less和more fewer 较少的；更少的，few的比较级，修饰可数名词复数 我朋友比我的苹果少。 __________________________________ .
less 较少的；更少的，little的比较级，修饰不可数名词 我钱包里的钱更少了。 ____________________________________ .
more 更多的，many和much的比较级，可修饰可数名词，也可修饰不可数名词。 瓶子里的水更多了。 ______________________________ . 我们有更多的挑战。 ____________________________________ .
（3）There will be more pollution. in five years. in five years 五年后，提问―in + 时间段‖时用特殊疑问词how soon in 是指以现在时间为起点的―在一段时间以后‖，也可以表示―在将来多少时间之内‖，句中的谓语动词要用一般将来时态。 after常常指以过去时间为起点的―在一段时间之后‖，所以它与过去时态连用。当after指某个特定的未来时刻或日期之后，或指以将来某一时间为起点的若干时间之后时，它可以与将来时态连用。 如：He started on Sunday and arrived in Beijing after three days.他星期天动身，3天之后到达北京。 I‘ll be free after Friday. 我星期五之后有空。
注意： few 和little 表示否定，意为“几乎没有”； a few, a little表示肯定，意为“有一点儿”。 a. 他两天以后回来。__________________________________. b. 我能一小时以内完成作业。______________________________. 4、合作交流:畅想未来 What do you think our city will be like? Discuss in groups and write about it. 至少六条，you can use there will ……….there won‘t be ……….
