a.Thepopulationof＋某地＋be＋数词(该句型中population前用冠词the);b.某地＋hasapopulationof＋数词＋(people)(该句型中population前用冠词a)。（3）“某地有多少人口”要用“Whatisthepopulationof...?”或“Howlargeisthepopulationof...?”提问。（4）表示人口“多”要用huge或large修饰，表示人口“少”要用small修饰。2.Feelfreetoaskmeanythingontoday’sGreatWalltour.(教材第50页)

feelfree是英语口语中一个常用表达。若有人让你feelfreetodosomething，就是让你无需拘束，只管按照自己的意愿去做某事。e.g.:—CanIuseyourbathroom?我可以用一下你的卫生间吗？—Yes,feelfree.可以，请随意。3.AsfarasIknow,therearenoman-madeobjectsasbigasthis.(教材第50页)asfarasIknow是一个固定的表达方式，还可以说sofarasIknow，意思是“据我所知”。e.g.：AsfarasIknow,Jack’sgottwinsisters.就我所知，杰克有一对孪生姐妹。They’renotcomingtoday,sofarasIknow.他们今天不来了——就我所知是这样的。4.1,025metersdeep1025米深（1）meter（美式英语）用作可数名词，意为“米；公尺”，英式英语拼写为metre。e.g.:Itisabout500metersfrommyhometoschool.从我家到学校大约500米。（2）deep用作形容词，意为“深的；纵深的”。“某物深度”的表达方式为：基数词+表示“度量”的名词+deep。e.g.:Theholeis10metersdeep.这个洞10米深。【拓展】英语中长、宽、高、重量的表达法：（1）可以用“基数词+单位词（meter,foot,inch,kilogram等）+in+名词（length,width,height,weight等）”表示。e.g.:Heissixfeetinheight.他有六英尺高。（2）还可用“基数词+单位词+形容词（long,wide,high等）”表示。e.g.:Theriveris5,200meterslong.这条河5200米长。5.Wow,that'samazing!哇，真令人惊奇！（教材第50页）amazing用作形容词，意为“令人大为惊奇的；令人惊喜（或惊叹）的”。其主语或所修饰的名词通常是事物。动词形式是amaze，意为“使吃惊；使惊奇”。e.g.:Thisisanamazingstory.这是一个令人惊奇的故事。【拓展】amazed用作形容词，意为“（感到）惊异的；吃惊的”。其主语或所修饰的名词通常是人。e.g.:Hewasamazedatthenews.他对这个消息感到很吃惊。一、单项选择。()1.—Howtallheis!—Yes,heis________thananyotherstudentinhisclass.A.tallB.tallerC.tallestD.moretall()2.Wedon’thavemuchhomeworknowandourschoolbagsare________theyusedtobe.A.asheavyasB.notasheavyasC.asheavilyasD.notasheavilyas()3.—Whichcountryhas________population,China,AmericaorJapan?—China,ofcourse.A.biggestB.themostC.thebiggestD.thesmallestBBCExercises()4.—________istheNile?—It’s6,671kilometerslong.A.HowlongB.HowfarC.HowdeepD.Howhigh()5.As________asIcansee,therearenomistakes.A.longB.farC.soonD.quicklyAB二、根据汉语意思完成句子。1.据我所知，
