2、与have gone都表示如今完成时态，说明动作已经发生了，但它们之间的含义是有不同的。1"have been in + 地点名词"或者"have been + 表位置的副词"含义是"在某地呆得过多久"。例如：Mr Zhang has been in this school for ten yearsHe knows everyone here.张先生在这所学校呆了十年。I have been here since I began to workIt"s just like my home.我工作以来一直呆在这里。2&quo

3、t;have been to +地点名词"表示"曾经到某地去过多少次"。例如：Miss Brown has been to China twiceThat"s why she speaks Japanese very well.布朗小姐来过中国两次。Have you ever been here before?你以前到过这儿吗？3"have gone to +地点名词"或"have gone + 表位置的副词"其含义是"到某地去了"人已不在此地，注意：这种构造不用于第一人称，也不用于第二人称，它

4、仅用于第三人称。请看下面一段对话：A: Where"s Tom?B: He"s gone to the shop.A: Has Mary gone there with him?B: No, she hasn"t.2.Businessmen are afraid of newspapers and TV stations.生意人害怕报纸和电台。be afraid of 意思是"害怕"。afraid是形容词，在句中只能作表语，后跟名词或动词的-ing形式指自己不能决定而突然发生的事，与frightened的意思一样。be afraid后也可跟动词

5、不定式表示"害怕做某事"即：be afraid to do sth.。另外，afraid后还可跟that引导的宾语从句，意思是"担忧，恐怕"。例如：1I am afraid of mice.我害怕老鼠。2Don"t be afraid of making mistakes.不要怕犯错误。3I"m afraid to tell her the truth.我不敢告诉她真相。4I am afraid you are ill.恐怕你是病了。5 I"m afraid (that) we may not catch the train

6、.我担忧我们可能赶不上火车。3.As soon as other people hear it, they go out with their rubbish and throw it in.当人们一听到它，他们就出来把垃圾扔进去。as soon as -就，引导时间状语从句，表示主句的动作紧跟从句的动作发生。必须注意 as soon as possibleone can，它表示"尽可能快地"。例： 1He"ll write to me as soon as he gets to Beijing他一到北京就会给我写信。2You should do your wor

8、t"s very important to take care of our environment.5It"s our duty to keep our environment clean and tidy. 保持我们的环境干净整洁是我们的责任。1it在这里是形式主语，真正的主语是"to keep our environment clean and tidy"又如：It"s a pleasant way to help keep our city clean.2keen后面可跟带如今分词的复合构造。如：He kept me waiting f

9、or a long time yesterday他昨天让我等了很长时间。keep后面也可跟带形容词的复合构造。如：You should take more e_ercise to keep you healthy你应该多运动来保持安康。6If everyone makes a contribution to protecting the environment, the world will bee much more beautiful.假如每人都对保护环境做出奉献，那么世界将变得更加美丽。make a contribution to意思是"对做奉献，捐赠"。to是介词后

10、跟名词或动词的-ing形式。例如：lThomas made a great contribution to the world托马斯-爱迪生对世界做出了很大的奉献。2It is our duty to make a contribution to protecting the environment为环境保护做奉献是我们的责任。make是英语中非常活泼的动词之一，和不同的词搭配具有不同的含义。又如：make a face做鬼脸 make a living谋生make a mistake犯错误 make friends with交朋友make fun of开玩笑 make one"s
