1.一般疑问句
以动词be，have或助动词、情态动词开头，以yes或no作回答的问句叫做一般疑问句。回答时可以用完整的句子回答，但大多数情况下只需作简略回答。如：
Is this your pencil 这是你的铅笔吗
Yes, it is. 是的。
Language points
2.no和not
二者都是“不”的意思, 但用法不同。前者可单独使用, 用于回答一般疑问句，反义词为yes; 后者不能单独使用, 要和be动词、助动词等一起构成否定句。
例如：
Is this your pencil 这是你的铅笔吗
No, it isn’t.不, 不是。
It is not my book.这不是我的书。
3.Excuse me，Grace.打扰了，格雷丝。
①excuse me 意为“劳驾，打扰了；对不起”，是说英语国家的人常挂在嘴边的话语，常用于当你要打扰别人，如借东西、问路、插话、中途离开等场合而向对方表示歉意。
如：Excuse me.Is this your ruler？请问，这是你的尺子吗？
②me “我(I的宾格形式)”，通常放在动词后作宾语。
4.No，they're Bob's.不，它们是鲍勃的。
Bob's 在这里是名词所有格形式，意为“……的”。名词所有格表示名词之间的所有关系，常用 's来表示。以后会详细学习，在这里作初步介绍。
【拓展】以s结尾的复数名词，在其后只加'。
如：teachers' office 教师办公室
8.What about...？意为“……怎么样？……好吗？”与how about 可互换使用，常用来询问消息或提出建议。后常接名词、代词或动词的 ing形式。
Thank you for your help，Anna.谢谢你的帮助，安娜。
Thank you for＝Thanks for 意为“为……而感谢”，for是介词，后接名词或动词的 ing形式。
