3. 【辨析】get to/reach/arrive都表示“到达”不同点：get to+地点；reach+地点arrive at+小地点（车站等）；arrive in+大地点（国家等）【解析】①get to与地点副词（here/there/home…）不用介词toE.g. I want to go to Beijing.I got home at 15:00.①arrive是不及物动词，后面若接地点名词则要和in/at连用，接地点副词时则不用介词。
E.g. I arrived home at 15:00. = I got home at 15:00.He arrived in Shanghai yesterday.①reach是及物动词，后面直接接地点名词或副词。
E.g. When will they reach here?6. 辨析take,bring▲take“带走，拿走”，指把东西从说话地带到别的地方。

②remember doing sth.记得已做过某事（已做）E.g. I remember seeing him once.③remember to do sth.记得要去做某事（还没做）E.g. Remember to post the letter for me.→反义词：forget “忘记，忘了”，用法和remember相同。

I had fun in the park last Sunday.13. be in bed“在床上、卧床”（注：in 和bed之间不能用冠词，bed也不用复数）E.g. He is in bed for 10 years.Dave has to be in bed early every night..14.No talking !“禁止交谈！”no后面加上名词或动名词doing表示不要做某事。
与don't +do的用法相似。
E.g. No wet umbrellas! / Don't put wet umbrellas here! 禁止放湿雨伞No food! / Don't eat food here! 禁止吃食物No smoking! / Don't smoke here! 禁止吸烟15. dish名词，意为“碟，盘”，做餐具讲时，常用复数形式，其前常加the。

【辨析】dish＆platedish和plate都是“盘，碟”的意思，它们的区别在于：▲dish可以泛指就餐时所用的餐具，包括盘、碗、碟、杯、刀、叉等，特指较深的盘子。
E.g. Please dry the dishes and put them away.▲plate 指较平的盘子、碟子, 可用来盛汤，也可用来装菜。
E.g. Our host was very generous, heaping a plate of food to us.16. practice①practice 作及物动词，意为“练习，训练”，其后可跟名词、代词或动名词做宾语。
