Meat is healthy but too much meat is not good for children.肉是健康食物,但吃太多的肉对孩子们没有好处。【点拨】but在此作连词,连接两个并列的句子成分,意为“但是”,表转折。如:I like cola very much but it isn’t healthy.我非常喜欢可乐,但它不健康。【延伸】but可作介词,意为“除……之外”;还可作副词,意为“仅仅;只有;才”,固定短语not...but...,指“不是……而是……”。如:①There is no one but me.除我以外,这里没有人。②I finished my homework but half an hour ago.半小时前我才做完作业。2. Eat the right food and be healthy.吃合适的食物,保持健康。【点拨】(1)这是并列连词and连接的两个祈使句。祈使句用来表示命令、请求、劝告或建议。肯定的祈使句中动词一律用原形,如上句中的eat与be。如:①Please be quiet.请安静。②Stop talking, please.请停止讲话。【延伸】祈使句的否定形式是直接在谓语动词前加don’t。如:Don’t be late for class again!请不要再上课迟到了!(2)be healthy意为“保持健康”,其中be是系动词,相当于stay或keep,后接形容词构成系表结构。如:Be/Stay/Keep calm when you are in danger.处于险境时你要保持镇定。3. A bit tired 有点儿累吗?【点拨】(1)此句是个省略句,其完整表达应为Are you a bit tired 。(2)a bit意为“有点儿;稍微”,可用来修饰形容词或副词,此时相当于a little。a bit也可修饰动词。如:①My mother is a bit/little fat.我妈妈有点儿胖。(修饰形容词)②He walks a bit/little fast.他走得有点儿快。(修饰副词)③Can you open the window a bit 你能把窗户稍微打开点儿吗?(修饰动词)【延伸】a bit of意为“一点”,修饰不可数名词,相当于a little。如:There is a bit of/a little milk in the bottle.瓶子里有一点牛奶。4. It is important to remember: eat well, stay healthy, and don’t get fat!记住这句话很重要:吃得好,保持健康,不发胖!【点拨】(1)It is important to do sth.是一个固定句型,表示“做某事很重要”。it作形式主语,真正的主语是后面的动词不定式。如:①It’s important to learn English well.学好英语很重要。②It’s easy to answer this question.回答这个问题很容易。(2)remember为动词,意为“记住;想起”,后可接名词、代词、动词不定式或动名词形式作宾语。如:①Do you remember the story 你记得那个故事吗?②We still remember him.我们仍记得他。【辨析】remember to do sth. 与remember doing sth.remember to do sth. 意为“记住要做某事(此事还未做)” Please remember to close the door when you leave. 你离开时要记得关门。remember doing sth. 意为“记得做过某事(此事已做)” I remember telling you the story. 我记得给你讲过那个故事。(3)well在此作副词,修饰动词eat,意为“好”。【注意】修饰实义动词时,不能用形容词good,而要用副词well。如:①She speaks English very well.她英语讲得很好。②Jim draws quite well.吉姆画画相当好。 展开更多...... 收起↑ 资源预览
