Lets have a hamburger.我们吃个汉堡包。lets=let us, let后面用动词原形即Lets do sth.“让我们干吧。”例如：Lets have a rest.让我们休息一下吧。Lets play games.让我们做游戏吧。注意lets开头的祈使句，其反意疑问句在句末加shall we？表示包括听话人在内的一种建议。如果不表示建议，而是提出一种请求，表示允许，不包括听话人在内时，则let us不缩写成lets，其反意疑问句为will you?Lets play basketball, shall we?我们踢篮球，好吗？（表示建议）Let us see your picture, will you?让我们看看你的图画，可以吗？（表示请求允许）have动词，“吃、喝；有”。例如：Would you have a cup of tea?你要喝杯茶吗？What do you have for breakfast?你早饭吃些什么？2. You are always hungry, Eddie.你总是饿，埃迪。always副词，“一直，总是”，是一个频率副词，常用于一般现在时。例如： She always has lunch at home.她总是在家吃午饭。 The sun always rises in the east.太阳总是从东方升起。 hungry形容词，“饥饿的”，其反义词是full，在句中作表语。例如： Are you hungry?你饿了吗？I always feel hungry after school.放学后我总是觉得饿。3.You never exercise.你从不锻炼。never副词，“从不，永不”，本身具有否定意义，语气比not重，用never表示否定时，不需要加助动词“not”。例如：I never go to school late.我上学从不迟到。She never writes to her father.她从不给她的父亲写信。exercise动词，“锻炼，训练”，在句中作谓语。例如：Mikes sister often exercises her voice in the morning.麦克的姐姐经常在早晨嗓子。He is exercising the boys in swimming. 他正在训练男孩子游泳。名词，“训练、锻炼（单数）；做操；练习、习题（复数）等”。例如：Youd better take more exercise.你最好多锻炼。Eat less and take more exercise, you will be thin.少吃饭，多运动，你会苗条的。Have you finished your Chinese exercises?你的语文作业做完了吗？do morning exercises做早操do eye exercises做眼睛保健操4. I want to be a dancer.我想当一名舞蹈演员。want to be“想成为”，want动词，“想，想要”其后可接名词或动词不定式作宾语，也可宾语接动词不定式，即want sth想某物，want to do sth.想做某事；want to to do sth.“想让某人做某事”。例如：I want some black tea.我想要些红茶。What do you want me to do? 你想要我做什么？ be动词原形，“做，成为”。例如：I want to be a doctor.我想成为一名医生。Dont be late!别迟到！5.Its important for a dancer to be healthy.对一个舞蹈演员来说健康是很重要的。常见的句型是：It is+ adj.+ for/of sb to do sth。例如：It is dangerous for children to swim in the river.孩子在这条河里游泳很危险。It was careless of you to do that.你这么做真粗心。6. Before, I seldom ate fruit and vegetables.以前，我不常吃水果和蔬菜。 seldom副词，“很少，不常、难得”，其反义词是often。通常置于行为动词之前；助动词和be动词之后。是一个表示否定意义的副词。例如：Mrs. Brown seldom goes out.布朗夫人很少外出。Millie is seldom late for school.米莉上学很少迟到。7.I ate a lot of sweet snacks between meals.在两餐之间我吃了许多甜食。between介词，“在（两者之间）”，后面可以跟名词或代词，跟代词时要用宾格。例如：Put the desk between us.把课桌放在我们俩中间。 betweenand“在和之间”，它限于两者之间；如果是三者之间或三者以上，要用介词among。between和and之间可以是两个人，也可以是两个不同的物或两个点（时间、数字、场所）。例如：Peter sat between Mary and Jane.彼得坐在玛丽和简之间。The shop opens between 9 a.m. and 5 p.m.商店在上午九点和下午五点间开门。Mary is sitting among the children.玛丽坐在孩子们之中。8.I know that sweet snacks are not good for me.我知道甜零食对我没有好处。be good for“对有益（有用）”，后接人或事物的名词。例如：Sunshine is good for your plants.你的花草要多晒太阳。Is this kind of food good for me?这种食物对我身体有益吗？This cream is good for bums.这种油膏治烧伤和烫伤很管事儿。Milk is good for children. 类似的固定词组还有：be good at“擅长，善于”, 后接名词，代词或动名词。例如：Kate is good at English.凯特擅长英语。Mike is good at playing football.麦克擅长绘画。be good to“对好（和善、慈爱）”，后接表示人的或要格化的名词。例如：She is good to me.她对我好。9.Now, I always eat an apple for breakfast.现在，我总是早饭吃一个苹果。 eat sth. for breakfast/lunch/supper=have sth. for breakfast/lunch/supper“早饭/午饭/晚饭吃”。例如：I ate some bread for breakfast.=I had some bread for breakfast.早饭我吃的面包。What did you eat for supper?=What did you have for supper?晚饭你吃得什么？10.
