Unit 8 I'll help to clean up the city parks.单元知识小结思维导图知识要点知识要点一:I'll help to clean up the city parks. 我将帮忙清理城市公园。(1) clean up意为“打扫(或清除) 干净”，而clean则含义较单纯，意为“打扫；把……弄干净”。例如：We must clean up the classroom after school.放学后我们必须把教室打扫干净。She often helps her mother clean the house .她经常帮助她妈妈打扫房间。(2) 经常与up连用的短语还有：set up“建立； 创立；开办”cheer up“使高兴起来”think up=come up with“想出”注意:clean up，cheer up，set up，call up，fix up，look up，put up和think up都是由动词和副词构成的动词词组。若代词作宾语则必须放在动词和up之间；若宾语是名词，则名词放在up之前或之后皆可。例如：Please clean up the classroom before going home.回家前请先打扫好教室。When I was ill，several friends sent me flowers to cheer me up.当我生病时，有几个朋友送给我鲜花使我高兴起来。They set up a new hospital nearby .他们在附近建了一所新医院。We must think up a good plan.我们得想出一个好计划。 知识要点二：Yeah，a lot of old people are lonely. 是的，许多老人是孤独的。lonely作形容词，意为“孤独的；寂寞的”【辨析】lonely / aloneHe is alone. 他独自一个人。I was traveling alone in the lonely mountain.I didn't feel lonely though I was alone.我独自走在荒凉的山野里，虽孤身一人，但并不感到寂寞。知识要点三：Some people even stop doing their jobs for a few months to a year to move to another country，like one of the countries in Africa，and help people there.一些人甚至离职几个月到一年去另一个国家，像非洲的一个国家，帮助那儿的人们。(1) 辨析训stop doing与stop to do sth.(2)move此处用作不及物动词,意为“迁移；搬家；离开”move to意为“搬到(某地) ”。例如：She moved to California last year. 去年她移居到了加利福尼亚州。[拓展】①move作不及物动词， 还可意为“移动；运动”。例如：Don't move，or I'll shoot.不许动，否则我就开枪了。②move作及物动词，意为“移动”。例如：I can't move my feet.我的脚动不了了。 (3)one of+复数名词/代词意为“.....之一”。当one of后面接复数名词时， 复数名词前需加定冠词the。此结构作主语时，谓语动词用单数形式。例如：One of us has a travel guide .我们中的一个人有旅游手册。【拓展】one of+the+形容词最高级+复数名词意为“最…之一”。例如：Shanghai is one of the largest cities in the world .上海是世界上最大的城市之一。知识要点四： I take after my mother.我长得像我妈妈。【辨析】take after /look like/be similar to①take after和look like都有“长得像”的意思，一般情况下可以互换使用。look like多用来指外貌；而take after不单指外貌，而且指言行、性格。例如；The girl must be Mary.She looks like her mother.那个女孩一定是玛丽，她像她的妈妈。Jack takes after his father ,for he is always cheerful.杰克像他的父亲，总是很快乐。②be similar to sb./sth.表示“和某人/某物相似”也可以和take after互换使用。similar作形容词，意为“相仿的；相似的”例如：My problems are very similar to yours.我的问题与你的很相似。I am similar to her.我和她相似。知识要点五：.......I was excited about the idea of having a dog.......我对拥有一只狗的主意感到很兴奋。(1)be excited about意为“对…感到兴奋、激动”例如：I was excited about going to the zoo.我对去动物园感到兴奋。(2) excited形容词，意为“激动的;兴奋的” 主要用来修饰人。She is so excited that she can't say a word.她激动得一句话也说不出来。【辨析】excited与excitinglonely adj.孤独的；寂寞的有浓厚的感情色彩aloneadv.&adj.单独地(的)陈述一个客观事实stop doing sth.意为“停止做某事”,停止的是正在做的事，相当于don't do sth.It's time to have a class.Stop laughing!到上课的时间了。不要笑了!stop to do sth.意为“停下来去做某事”，指停下目前的事而去做另一件事。Class is over. The students stop to do eye exercises.下课了。学生们停下来去做眼保健操。excited意为“兴奋的”，指人感到兴奋，是人的感受，常作表语 She's very excited after hearing it.听了这件事后她很激动。exciting意为“令人兴奋的；使人激动的”，指人、事、物本身含有令人兴奋的特征；可作表语或定语He told us an exciting story.他给我们讲了一个使人激动的故事。
