Shop: n.商店；关于shop常用的短语，go shopping:去商店买东西；moment: n.片刻，瞬间；关于moment需要掌握的三个常见短语：at the moment:就在此时，现在；for the moment:当前，目前；in a moment:很快，一会儿；二、短语句型语法1、It is eight O′clock.现在是八点钟此句中需要掌握用英语如何表达时间。

①如何表达时间？在英语中常用的时间表达方式有两种。

一种是顺读法，先说时针所指的数字，后说分针所指的数字。

如9:20的英语表达为：nine twenty; 9:50的英语表达为：nine fifty.另一种是倒读法，就是先说分针所指的数字，再说时针所指的数字。

比如9:20的英语表达为：twenty past nine; 9:50的英语表达为：ten to ten; 9:30的英语表达为：half past nine;在英语中，通常把时钟分成两半，前半小时用past（过），后半小时用to(差)来表达时间。

在表达15分钟及45分钟时，可以用quarter(一刻)，同理，前半小时用past, 后半小时用to.比如9:15:的英语表达式为：a quarter past nine; 9:45的英语表达式为a quarter to ten.②如何询问时间询问时间常见的几种表达方式：What time is it? What is the time?What time is it by your watch?Excuse me, have you got the time?2、they are going to school on foot.他们正步行上学On foot:步行,是方式状语，另外表达用什么方式、凭什么工具经常用by加具体的名词，如：by sea:乘船by ship:乘船by bus:乘公共汽车by bike:骑自行车by air:乘飞机by plain:乘飞机3、课文中重点短语集锦：go to school:去上学on foot:步行stay at home: 呆在家里drink tea:喝茶in the living room:在卧室里in the garden:在花园里do homework:做家庭作业at the moment:此时此刻read newspaper: 读报纸4、重点语法：现在进行时（一）现在进行时是指正在发生的动作或事件，动作发生的时间是“现在”，动作目前的状态是“正在进行中”。

基本结构现在进行时的基本构成是：主语+be（am/is/are）+动词的现在分词形式(v+ing),具体表现如下：第一人称单数I+am+doing+Sth.I am reading a book:我正在看书第一人称复数We+are+doing +Sth.We are playing football now:我们正在踢足球第二人称单(复)数You+are+doing+Sth.You are looking at the blackboard: 你们正在看黑板第三人称单数He（She，it）+is+doing+Sth.She is playing basketball:她正在打篮球第三人称复数They+are+doing +Sth.They are watching TV:他们正在看电视动词现在分词的变化规则①一般情况下，直接在动词后加－ingwork ---- working; sleep ----- sleeping; study ----- studying ②动词以不发音的－e结尾，要去－e加－ingtake ----- taking make ----- making dance ----- dancing come – coming close – closing ride – ridingmove – moving have – having③重读闭音节,且末尾只有一个辅音字母的动词，要双写词尾字母，再加－ingcut ----- cutting put ----- putting begin ------ beginningsit--- sitting get---getting shop---shoppingswim--- swimming run ---running④以ie结尾的动词，把ie变成y再加－ing，常用的有以下三个：lie ----- lying tie ----- tying die ----- dying基本用法①现在进行时表示现在正在进行的动作或发生的事情：I am reading a book:我正在看书She is playing basketball:她正在打篮球They are watching TV:他们正在看电视②现在进行时表示“现阶段内”正在发生的事情，动作不一定正在进行：Tom, are you still working in that factory?汤姆，你还在那家工厂工作吗啊？She is teaching at a night school。

她在夜校教书Do not take the ladder away, your father is using it.别把梯子拿走，你父亲在用呢啊（不一定正在用）句型转换①在现在进行时的状态之下，把肯定句变成一般疑问句，只需要把be提前即可。

My father is reading a newspaper 变成一般疑问句：Is your father reading a newspaper?Yes, he is .No, he is′t②在现在进行时的状态之下，把肯定句变成否定句，只需在be动词之后加not即可，如：I am working→I am not working.He is running→He isn't runningThey are playing football→They aren't playing football.标志词:a t the moment; now；look!；listen!等课后练习（一）It was half-past eight in the morning.
