There are two hundred buses at the station.这个车站上有二百辆公共汽车。 拓展hundreds of意为“上百的；数以百计的”，是不确切的数量，此时hundred后面要加-s，词前不能有数词。eg.Hundreds of people come to visit our village every day.每天有上百人来参观我们的村庄。2. every day意为“每天”，为固定搭配。其中，every作形容词，意为“每一；每个”，后面接单数可数名词。eg. I go to school by subway every day.我每天乘地铁去上学。eg. She knows every student of the class.她认识班里所有的学生。辨析：every day与everydaya) every day意为“每天”，当做副词讲，常放在句首或句末，用作时间状语。eg. When do you get up every day?你每天几点起床？b) everyday是形容词，意为“日常的”，后面可直接跟名词，在句中作定语。eg. She wears everyday clothes to work.她着便装上班。3. How far is it from your home to school? 从你家到学校有多远？ “How far is it from A to B?”意为“A地到B地有多远”，是询问两地之间距离的句型。回答常用：“Itsmeters/ kilometers/ miles (away).有米/千米/英里（远）。”或“Its meters/ kilometers/ miles (away) from A to B.从A到B有米/千米/英里（远）。”4. How long does it take you to get to school? 到达学校要花费你多长时间？ （1）how long在此处意为“多久；多长时间”，主要用于询问动作持续的时间.eg.How long does it take you to get here from your home?从你家到这里要花多长时间？About thirty minutes大约三十分钟。（2）take在此处用作及物动词，意为“花费（时间）”。常用句型：It takes sb. some time to do sth.“做某事花费了某人多长时间”。其中，it是
