We think that everyone should use public t________.5. I guess everyone in this city is trying to improve the e_________.【课堂探究】一、现在进行时：概念：表示现阶段或说话时正在进行的动作及行为。
时间状语：now, at this time, these days, etc. 基本结构：am/is/are+doing 否定形式：am/is/are+not+doing. 一般疑问句：把be动词放于句首。
二、used to的意思是“过去经常”，其中的to是不定式符号，不是介词，所以其后接动词原形(不接动名词)。
三、现在完成时：概念：过去发生或已经完成的动作对现在造成的影响或结果，或从过去已经开始，持续到现在的动作或状态。
时间状语：recently, lately, since…for…,in the past few years, etc. 基本结构：have/has + done 否定形式：have/has + not +done.四、被动语态：概念：当主语为动作的承受者时，谓语要用被动语态。
基本机构：“助动词be＋及物动词的过去分词”构成。
含有情态动词的被动语态由“情态动词＋be＋及物动词的过去分词”构成。
助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。
五、情态动词should后接动词原形。
（1）表示“应该，应当” You should help your mother with the housework. 你应该帮你母亲做家务。
（2）表示“可能，该(=will probably) ”He should arrive soon他可能很快就到了。
