八年级（下）英语 Unit1-5 知识点 Unit 1?Will people have robots? ★一般将来时表示将要发生的动作或存在的状态。本时态标志词： 1.含tomorrow; next…短语；???? 2.in+段时间；? 3.how soon；4.by+将来时间；???5.祈使句句型中or/and sb. will do? 例Be quick, or you will be late=If you don’t be quick, you will be late6.在时间/条件状语从句中, 如果从句用一般现在时, 主句用将来时（另见Unit 5）? 比较be going to 与will:be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些。 如： He is going to write a letter tonight.?? ?He will write a book one day. 2. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。He is seriously ill. He is going to die. He will be twenty years old. 3. be going to 含有“计划，准备”的意思，而 will 则没有这个意思，如： She is going to lend us her book.???????????? He will be here in half an hour. 4.在条件从句的主句中，一般不用 be going to, 而多用will, 如：If any beasts comes at you, Ill stay with you and help you.　　掌握了它们的这些不同，你就能很好的区分be going to与will了。 There will be fewer trees、more buildings and less pollution in the future.
