Unit 1 will people have robots?
语法知识点
一、Will 和 be going to 的区 别
be going to与will两者都可表示将要发生的事、将要去 做某事，但它们有如下几点区别：
1. 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.
A. is B. are C. was D. were
2. There ________ two knives in the pencilbox. [03哈尔滨]
A. are B. be C. is D. am
3. There ________ a pair of shoes under the bed. The shoes ________ mine. [04兰州]
[扫描1]
根据句子的时间状语或上下文暗示、衔接等，在 初中阶段be的形式不外乎有这么几种：
①现在时(is / are)、过去时(was / were)、将来时 (will be)、完成时(have / has / had been)；
②可以与情态动词连用，组成there +情态动词 +be的形式，表推测语气；
[扫描2] be的形式受后面靠近它的主语在人称和数
上的制约，必须采取就近原则，与临近的主语 保持一致，必须看清楚there后跟的是可数名 词，还是不可数名词。还必须注意既有可数名 词又有不可数名词的时候，be的形式的临近一 致性。如:There is a bag of rice, two baskets

eg：I myself did the homework last night.昨晚
是我自己做的家庭作业。(作主语同位语，可紧跟主语之后，也可置 于句末)
You can go and ask John himself.你可以去问约翰本人。(作宾语同位语
，紧跟在宾语之后)
【拓展】含反身代词的常见短语：
②表示命令和要求时，语气比较强烈。
eg：You shouldn't be so careless.你不应该这么粗心。 ③表示预测和可能性。
eg：He should be a teacher.他应该是一名老师。
